[Botany • 2025] Nepenthes higaonon (Nepenthaceae) • A New Species of Pitcher Plant from the northern Mindanao, Philippines


Nepenthes higaonon  Lagunday & V.B. Amoroso, 

in Lagunday, Baul, Ansihagan et Amoroso, 2025. 
 
Abstract
Nepenthes higaonon (section Alatae) is described as a new species from the gravel substrates of northern Mindanao, Philippines. It is morphologically similar to N. viridis from which differs in having a non-decurrent leaf-to-stem attachment (vs. slightly decurrent in N. viridis), rounded leaf apex (vs. acute), 3 longitudinal veins on each side of the midrib (vs. 1–2), monomorphic pitchers (vs. dimorphic) aerial pitchers cylindrical upper 1/3rd (vs. infundibular upper 1/3rd), aerial pitcher lid flattened, ovate, angled up to 90° completely exposing the opening (vs. domed, oval to cordate, angled up to ca. 60 ° covering the opening), aerial pitcher peristome anterior with shallow depression (vs. often raised), inflorescence 1-flowered (vs. 2-flowered), and by its climbing stems up to ca. 10 m (vs. up to ca. 4 m). The species described is assessed herein as Critically Endangered according to IUCN criteria, facing threats of poaching, shifting cultivation, without legislative protection and calls for immediate conservation efforts.

[Botany • 2025] Pitcairnia zapoteca (Bromeliaceae: Pitcairnioideae) • A New Species with nocturnal anthesis from Oaxaca, Mexico

 

Pitcairnia zapoteca I. Ramírez, G. Carnevali & K. Romero,   

in Ramírez-Morillo, Carnevali, Romero-Soler, Pinzón, Tamayo-Cen, Flores et Martínez, 2025. 

Abstract
Background: Pitcairnia is the third largest bromeliad genus in Mexico with 57 species and ca. 82.5 % endemism, and is characterized mostly by zygomorphic, ornithophilous flowers of diurnal anthesis in several hues of red, orange, or yellow, whereas white or green flowers are uncommon. Moreover, there are just a few species with nocturnal anthesis in Megamexico. One of them is documented and discussed here.

Questions: Is the Pitcairnia with campanulate, fragrant flowers of nocturnal anthesis from Oaxaca different from other species with similar characters native to Mexico and the Neotropics and what is its conservation status?

Studied species: Pitcairnia abundans, P. lokischmidtiae, P. zapoteca.
Study site and dates: Oaxaca, Mexico, 2016-2024.

Methods: Live plants, herbarium material, protologues, and high-resolution images of herbarium specimens, both of the new taxon and of morphologically similar taxa, were studied and compared against each other. The conservation status of the new species was assessed using the IUCN criteria.

Results: Pitcairnia zapoteca is similar but different at the species level from P. lokischmidtiae from Jalisco; both share campanulate flowers of nocturnal anthesis and a musky or frutal fragances. The conservation status of the new taxon is assessed as DD.

Conclusions: Pitcairnia zapoteca is a new species, only known from the type locality in the state of Oaxaca and only one of three Mexican species with campanulate, white, yellowish or greenish flowers of nocturnal anthesis. The assessment the true conservation status of the new taxon requires detailed exploration of the SE portion of Oaxaca.

Keywords: actinomorphic flowers, endemic species, nocturnal anthesis

(Based on I. Ramírez & G. Carnevali 2459 (Holotype: CICY)).

Pitcairnia zapoteca I. Ramírez, G. Carnevali & K. Romero, sp. nov. 

Diagnosis. This new species resembles Pitcairnia lokischmidtiae. However, P. zapoteca differs by the fewer leaves per rosette (10-15 vs. (16-)18-25 in P. lokischmidtiae), shorter leaves (40-60 vs. 80-100 cm), which are also narrower (1.3-1.5 vs.  ca.  4.5  cm  wide),  and  deciduous  (vs. persistent); it also features shorter inflorescences (70-80 vs.  120  cm), larger floral bracts (1.5-2 vs. ca. 1 cm), sepals tinged dull brown-red (vs. totally green), pale-yellowish petals with distal, dull red brown tinges (vs. greenish white), the stigma surpassing the petals when the flower withers (vs.included), and ovary superior (vs. almost completely superior).

Etymology. The name zapoteca honors the Zapotecan people, an ethnic group that have traditionally inhabited the type locality area.

Bulbophyllum abuniorum Saputra & Schuit.,

in Saputra, Schuiteman, Ulimpa, Fitrah Darwis, Junial, Nuburi et Santoso, 2025. 

Abstract
A new species of Bulbophyllum from section LepidorhizaB. abuniorum Saputra & Schuit., is described based on specimens from the Bird’s Head Peninsula, New Guinea. A detailed morphological description and diagnosis, information on distribution and ecology, and a preliminary conservation assessment are provided. A key to the species of Bulbophyllum section Lepidorhiza in New Guinea is also presented.

Keywords: Abun Tribe, Pegunungan Tambrauw, West Papua, endemic, indentification key



Bulbophyllum abuniorum Saputra & Schuit., sp. nov.

Diagnosis: Bulbophyllum abuniorum is similar to Bulbophyllum levyae Garay, Hamer & Siegerist (1995:176) especially in the shape of sepals and petals, the relatively long lip, and in the several simultaneously opening flowers (flowers usually opening one at a time in other species of sect. Lepidorhiza), but differs in having a slightly clawed lip at the base (vs. not clawed in B. levyae), densely irregular conical-subulate teeth all over the adaxial surface of the lip (vs. lip with papillae in the middle, smooth elsewhere), margin of lip laciniate basally, strongly serrate centrally, and crenate apically (vs. margin entire throughout).

[Ichthyology • 2025] Homatula gelao • A New nemacheiline Species of loach (Cypriniformes: Nemacheilidae) from the upper Yangtze River basin in Guizhou Province, southwestern China


Homatula gelao Xiao,

in G.-B. Xiao, Guo, Cao, Lin, WeXi Deng, Q.-Q. Xiao, Zhou, Zhang et Fang, 2025. 
仡佬荷马条鳅  ||  DOI: doi.org/10.3897/zse.101.141973 

 Abstract
Homatula gelao, a new species, is here described from the Wu-Jiang of the Yangtze River basin in Guizhou province, southwestern China. This new species belongs to the elongate-bodied group of Homatula defined by having a complete lateral line, sparsely scales hidden in skin on the predorsal body, and a slender body with a uniform depth. It, along with H. variegata, is distinguished from all other species of this group in having a broadly rounded caudal fin and a small number of scales sparsely scattered over the predorsal body. Both differ in body coloration, striped pattern on the predorsal body, and caudal-peduncle length. The validity of the new species is corroborated by distinct genetic distance divergence with closely related congeneric species and its monophyly recovered in a mtDNA COI gene-based phylogenetic analysis. It is separated from other Homatula species by a minimum of 8.2% Kimura 2-parameter distance in the COI gene.

Key Words: Homatula gelao, new species, morphological comparison, taxonomy, Yangtze River basin

Lateral (A), dorsal (B), and ventral (C) views of Homatula gelao, holotype, ZVTC 20200601, 127.6 mm SL, caught from Furong-Jiang, a tributary flowing into Wu-Jiang of the Yangtze River basin, at Huaiping Village, Daozhen Gelao and Miao Autonomous County, Guizhou Province, P. R. China.

 Homatula gelao Xiao, sp. nov.

Diagnosis: A member of the elongate-bodied group of Homatula defined by having a slender body with a uniform depth (9.2%–14.4% of SL), a complete lateral line, and a scarcely scaled or scaleless predorsal body. H. gelao resembles H. variegata in the presence of a broadly rounded (vs. truncate or obliquely truncate) caudal fin and scales sparsely scattered on the predorsal body (vs. predorsal body unscaled or sparsely scaled on the dorsum and flank), which distinguishes both from all other species of this group (H. berezowskii, H. guanheensis, H. laxiclathra, H. longidorsalis, H. oxygnathra, and H. tigris). It differs from H. variegata in possessing a body coloration of 17–18 brown vertical bars narrower than interspaces, particularly on the Caudal peduncle flank (vs. dense, undulating vertical bars slightly wider or equal to interspaces); a thick brown-black stripe running along dorsal midline from behind head to dorsal fin origin; and symmetrical black vertical bars on sides of body (vs. light brown spots on the dorsum and irregular markings on the sides of the body); and a longer (vs. equal) distance from the origin of the anal fin to the origin of the pelvic fin than the distance from the origin of the anal fin to the base of the caudal fin.

Sampling locality of Homatula gelao in the Huaixi-He, tributary to the Furong-Jiang in Huaiping Village, Jiucheng Town, Daozhen Gelao and Miao Autonomous County, Zunyi City, Guizhou Province, P. R. China; 2 June 2020, photographed by Guibang Xiao.

Red arrow indicates the natural habitat state of H. gelao. White square indicates the inhabitant situation of H. gelao.

Etymology: The specific epithet is named after Gelao (in Chinese spelling) nationality. The type specimens of the new species were collected from the Huaixi-He in Daozhen Gelao Autonomous County, northern Guizhou Province. The Chinese common name for H. gelao is suggested as “仡佬荷马条鳅”.

[Botany • 2021] Miconia waimiri-atroari (Melastomataceae: Miconieae) • A New Species from the Brazilian Amazon Forest


  Miconia waimiri-atroari  Meirelles & Caddah,

in Meirelles, Sartor, Chagas et Caddah, 2021.
 
Abstract
Miconia waimiri-atroari is presented here as a new species from the Brazilian Amazon Forest. This new species has discolorous leaf blades, inflorescences with scorpioid branches, and petals and antesepalous stamen connectives with glandular trichomes. It has been misidentified as Miconia argyrophylla, another species from the Amazon Forest that has this same set of characters. However, the new species has cylindrical young branches (vs. quadrangular in M. argyrophylla), stellate trichomes on leaf abaxial surface (vs. arachnoid), stamens with yellow filaments that turn red in old flowers (vs. stamens with white filaments that only turn pale in old flowers), and style with glandular trichomes (vs. glabrous). At the moment, the species is only known from a small area north of Manaus, state of Amazonas, Brazil. Morphological description, illustrations, general comments and comparison to other similar species are also provided.

Miconia waimiri-atroari sp. nov. 

Etymology:—The new species is named after the indigenous people of Waimiri-Atroari, whose territory is located near the BR-174, between Manaus (Amazonas) and Boa Vista (Roraima), where the species occurs. During the construction of the BR-174, mainly in the 1960’ and 1970’s, these people have suffered a massive genocide by the military government of that time, and lost part of their land to farmers, squatters and the state (Sousa et al. 2020).Besides the BR-174, the Balbina Dam and mining companies have also explored the land of the Waimiri-Atroari, contributing to population decrease from 3000 in 1972 to 350 people in 1983 (Damasio 2019). The epithet is a name in apposition.

[PaleoIchthyology • 2024] Miaojiaaspis dichotomus • A New Genus of galeaspids (Eugaleaspiformes: Tujiaaspidae) from the early Silurian Chongqing Lagerstätte, China

 

Miaojiaaspis dichotomus 
Chen, Li, Zhou, Shan, Y.-A. Zhu, Wang, Wei & M. Zhu, 2024


 
The early Silurian Chongqing Lagerstätte (middle Telychian) yields exceptionally preserved articulated jawless and jawed fishes. Here, we describe a new eugaleaspiform (Galeaspida, jawless stem-Gnathostomata), Miaojiaaspis dichotomus gen. et sp. nov., from the Chongqing Lagerstätte in Xiushan, Chongqing, China. The new form resembles Tujiaaspis vividus in the short medial dorsal canal, and the presence of the branching ends of the lateral transverse canal. They differ in that T. vividus has highly developed subordinate branches of the sensory canals that form a reticulate sensory canal system, and the median dorsal opening is more elongated. Our phylogenetic analysis recovers M. dichotomus and T. vividus as a monophyletic clade (Tujiaaspidae fam. nov.), which is supported by two synapomorphies: the short medial dorsal canal, and the branching ends of the lateral transverse canal. Tujiaaspidae forms a trichotomy with Shuyuidae and a clade comprising Anjiaspis, Sinogaleaspidae, Yongdongaspidae, and the ‘eugaleaspid cluster’. The sensory canal patterns in galeaspids are compared to show the transformation sequence of the sensory canal system in Eugaleaspiformes.

Family Tujiaaspidae fam. nov.
Type genus Tujiaaspis Gai et al., 2022.

Referred genus Miaojiaaspis gen. nov.
Differential diagnosis Tujiaaspidae differs from other families of Eugaleaspiformes in the short medial dorsal canal, and the branching ends of the lateral transverse canal.

Remarks Our phylogenetic analysis shows that M. dichotomus and T. vividus form a monophyletic clade supported by two synapomorphies.


Genus Miaojiaaspis gen. nov.
Type species Miaojiaaspis dichotomus sp. nov.

Etymology From Miaojia, Pinyin for the Miao People, a minority ethnic group in China, which is one of the two main autonomous minority ethnic groups in Xiushan County, Chongqing, and aspis (Gr.), shield.

Differential diagnosis M. dichotomus differs from T. vividus in a more subtriangular headshield, no highly developed subordinate branches of sensory canals and a shorter median dorsal opening.

Holotype An incomplete headshield with the trunk articulated, CIGMR V0125a, b (Figs. 2–3).
Referred specimens 8 complete headshields, CIGMR V0126–V0129, IVPP V28714–V28717 (Fig. 4).


Etymology From dichotomus (Latin), referring to the dichotomous ends of the lateral transverse canals.

Diagnosis Small-sized eugaleaspiform fish with a subtriangular headshield. Spine-shaped cornual and inner cornual processes caudo-laterally or caudally oriented. Longitudinal oval-like median dorsal opening. Pineal opening positioned behind the posterior margin of the orbits. Funnel-shaped supraorbital canals. Short medial dorsal canal.

[Ichthyology • 2024] Hypancistrus parkateje • A New Species of Hypancistrus Isbrücker & Nijssen 1991 (Siluriformes: Loricariidae) from the rapids of the middle Rio Tocantins

 

Hypancistrus parkateje
 Araújo, Ferreira, Monteiro & Wosiacki, 2024 


Abstract
The Hypancistrus genus is recognized in the Río Orinoco basin and Rio Xingu in the Guiana and Brazilian Shields, respectively. Some of its species are important in ornamental fishing. Despite this significance, many other undescribed species are still awaiting to be named. Here we describe a new species of Hypancistrus found on bedrock in the Rio Tocantins, representing an extension of the distribution of the genus. Also, a multigene phylogeny is presented to evaluate the taxonomic position of this species concerning congeners. The new species differs from all congeners by (1) hypertrophied odontodes on cheeks reaching beyond the cleithrum, (2) a supraoccipital crest conspicuously elevated, (3) a supraorbital crest slightly convex, (4) oblique bars on the anterior part of the body, (5) a dark E-shaped mark on the snout, (6) three oblique dark bars on the anterior part of the body and horizontal vermicular bars from the pectoral girdle to the posterior insertion of the dorsal fin, (7) a thin light gray bar on the posterior of the head extending across the branchial opening, (8) a tan background color, (9) a developed suspensorium with a diminished appendix in the metapterygoid, and (10) a dentary plate robust significantly fused with the angulo-articular bone. The molecular phylogenetic results show the new species forming a group with Hypancistrus zebra (Brazilian Shield—Rio Xingu) as a clade, a sister group of a monophyletic group consisting of all congeners from the Río Orinoco.

[Ichthyology • 2023] Lasiancistrus wiwa • Phylogenetic Revision of Whisker-cheeked Suckermouth Catfishes (Siluriformes: Loricariidae: Lasiancistrus) from east of the Andes: Five Species where once there were Two


Lasiancistrus wiwa
Poveda-Cuellar, Conde-Saldaña, Villa-Navarro, Lujan & Santos, 2024

 
Abstract
We integrated large sample sizes, morphometric and molecular data, and phylogenetic and species delimitation analyses to test the 17-year-old hypothesis that only two species of whisker-cheeked suckermouth catfishes (genus Lasiancistrus) occur in river drainages west of the Andes Mountains. Our results reject this hypothesis, demonstrating that, in addition to the previously recognized Lasiancistrus guacharote from Lake Maracaibo, a Lasiancistrus clade from west of the Sierra de Perijá contains at least four allopatric, genetically differentiated and morphologically distinct lineages. One of these lineages had no previous name associated with it and is described here as the new species Lasiancistrus wiwa. Phylogenetic relationships and geographical distributions of all five trans-Andean lineages are concordant with watershed boundaries and major mountain ranges that form these boundaries, with the following five freshwater basins or regions each containing a single species: Lake Maracaibo (L. guacharote), Rancheria River basin (L. wiwa), Upper and Middle Magdalena River and lower Cauca River basins (Lasiancistrus volcanensis), Upper Cauca River basin (Lasiancistrus caucanus) and Pacific Coastal watersheds between central Colombia and central Panama (Lasiancistrus mayoloi). Evolutionary relationships among these lineages suggest that Andean uplift-mediated vicariance contributed significantly to the cladogenesis and allopatric distributions of these fishes.

Here we describe the distinctive new species Gasteruption mamburrumurl sp. nov. from Leliyn (Edith Falls), Nitmiluk National Park, Northern Territory, Australia and document a host association with the native resin bee, Megachile micrerythrura Cockerell, 1910 (Megachilidae: Apoidea). The common name for the species is the "Mam-Burrumurl wasp".

Gasteruption mamburrumurl sp. nov.

Diagnosis. Gasteruption mamburrumurl sp. nov. is a distinctive species that is easily distinguished from other described Australian species based on the combination of body colouration; head and metasoma black, mesosoma reddish-brown, metatibia without cream patch, and areolate-rugulose sculpturing on the mesoscutum.

Distribution. The species is known only from the holotype locality at Leliyn (Edith falls), Nitmiluk National Park, Northern Territory, Australia. 

Etymology. In collaboration with First Nations elders and custodians of the Country in which this species was discovered, the species epithet mamburrumurl is derived from the Jawoyn language, combining the words mam meaning 'ghost' and burrumurl meaning 'wasp.' This name describes the distinctive floating searching flight pattern exhibited by these wasps. Hence, this species is commonly referred to as the “Mam-Burrumurl wasp”.

Abstract
The Torres Strait Islands lie between Cape York Peninsula, north-east Australia, and the southern coast of Papua New Guinea. The vertebrate fauna of these islands is a relatively depauperate mix of Australian and New Guinean species, with only two endemic species described to date. Here we describe a new species of Nactus gecko discovered during a targeted survey of Dauan Island in the northern Torres Strait. Nactus simakal sp. nov. is a genetically (ND2 mtDNA) and morphologically highly distinct species, with a banded pattern and a slender, elongate form. It is saxicoline, living on deeply piled boulder habitat, and is likely to be restricted to Dauan Island. Nactus simakal sp. nov. is currently known from a very small area and further surveys, and assessment of current and potential threats, are required to assess the conservation status of this species. Nactus simakal sp. nov. is similar in general appearance to N. galgajuga (Ingram, 1978), which is restricted to boulder-pile habitat 750 km to the south in mainland north-east Queensland but is readily distinguished from that species morphologically and genetically.

Diagnosis. A slender, elongate Nactus gecko with strongly banded pattern and prominently keeled subcaudal scales.
 
Etymology. The species name ‘simakal’ is in reference to Simakal Pad, the local language name for Mt Cornwallis (the mountain that dominates Dauan Island). The local language name was provided by Laurie Elisala, Torenzo Elisala, Abi Mooka, Tenny Elisala, and Thomas Mooka.
