Abstract

Two new species of Diploexochus are described. Diploexochus spinatus sp. nov. from Lapa do Honorato cave, located in the municipality of Iuiu, and Diploexochus obscurus sp. nov. from Água Escura I cave, located in the municipality of Carinhanha, both in the southwest of Bahia State, northeastern Brazil. Both species are likely to occur in caves due to anthropogenic impacts in the surrounding area (such as deforestation) and/or looking for the stable microclimatic conditions found in the subterranean realm. Additionally, D. echinatus is recorded in a cave in the municipality of Rurópolis, Pará State, northern Brazil. These represent the first records of the genus for subterranean environments.

Abstract

We propose the re-establishment of Dyckia tomentosa, after rediscovering its populations, the synonymization of Dyckia polyclada, and Dyckia magnifica as a new species from southern Brazil that is morphologically related to D. tomentosa. Descriptions of external morphology, leaf anatomy and pollen morphology, and comments on species distributions and habitats are provided. The informal species complex in which D. magnifica and D. tomentosa are placed is morphologically re-circumscribed and proposed here as the “Dyckia selloa complex”.

Abstract

A new form of small antelope is described from the Lower Pleistocene of the Taurida Cave in the Crimea. A new genus and species Tavridia gromovi is identified from a fragment of the skull roof with a horn core and the lower jaw. This small antelope differed from all known forms in the morphological features of the horn cores and the dental system. Based on the combination of characters, it is assigned to the tribe Antilopini (Eurasia and Africa, Middle Miocene to Recent). The discovery of T. gromovi in the Crimea testifies to the significant diversity of this group of antelopes in the middle of the Early Pleistocene.

Abstract

Fritillaria ecerii Balos & Eker sp. nova (Liliaceae) is described from the province of Mardin, SE Anatolia, Turkey. It is morphologically similar to F. melananthera in having a striped perigone, to F. caucasica and F. baskilensis in having a long style, and to F. assyriaca in having the same number of leaves. However, it clearly differs from F. melananthera and F. assyriaca mainly by its smooth style, longer filaments and more numerous bracts, and from F. caucasica and F. baskilensis mainly by its striped perigone and more numerous bracts. Diagnostic characteristics, a description, images, and a conservation assessment are provided.

[Ichthyology • 2023] Glyptothorax irroratus • A New Species of rheophilic catfish (Siluriformes: Sisoridae) from the Mekong River drainage

Glyptothorax irroratus

Ng a& Kottelat, 2023 

DOI: doi.org/10.1080/00222933.2023.2186278 

 

ABSTRACT

Glyptothorax irroratus, a new species of sisorid catfish from the Mekong River drainage in Laos and China, is described. It differs from its Indochinese congeners in having both large and small tubercles arranged irregularly on the lateral surfaces of the body and by combinations of colour pattern, morphometry (with particular regards to the eye, body depth, adipose fin and caudal peduncle) and thoracic adhesive apparatus morphology.

 

KEYWORDS: Sisoroidea, Sisorinae, Bagariini, Mekong River

Glyptothorax irroratus sp. nov.

Etymology: The Latin adjective irroratus (-us, -a, -um) means covered with dew; in zoology used to mean besprinkled with drops or particles. This is used in allusion to the irregular tuberculation on the sides of the body and caudal peduncle.

[Botany • 2023] Vincetoxicum sangyojarniae (Apocynaceae: Asclepiodoideae) • Molecular Phylogenetic and Morphological Analyses support Recognition of A New Species of Vincetoxicum from eastern Thailand

 DOI: doi.org/10.1007/s00606-023-01866-y 

Abstract

An unknown Vincetoxicum species has recently been discovered in eastern Thailand. It is a twiner that resembles in its morphology Vincetoxicum flexuosum s.l., a variable taxon widely occurring from tropical Asia to Australia. Morphological examination showed that despite similarities in growth habit, leaf shape, gross appearance of inflorescence structure and flower colour, these two elements exhibit substantial differences in both vegetative and floral characters that clearly distinguish one from the other, particularly shape of the flower bud and indumentum on the corolla lobes. In addition, we also evaluated phylogenetic relationships based on DNA sequence data for ITS, trnT-L, trnL and trnL-F markers of this new Vincetoxicum sp. with congeners (including, inter alia, new sequences of the two varieties recognized in Thailand of V. flexuosum s.l., i.e. var. flexuosum and var. tenue). The analyses demonstrated that the new Vincetoxicum sp. is not closely related to the taxa recognized in V. flexuosum s.l. Instead, it was retrieved as sister to a clade containing the African taxa, Vincetoxicum caffrum, Vincetoxicum lycioides and Vincetoxicum fleckii. Therefore, integrated analyses of morphology and molecular phylogeny revealed the new Vincetoxicum sp. to be a well-defined species clearly distinct from V. flexuosum s.l., as well as from all other known congeners. The morphological similarity between the new Vincetoxicum sp. and V. flexuosum s.l. likely resulted from convergence, leading to various taxonomic complications. We here describe it as a new species, Vincetoxicum sangyojarniae, sp. nov., and provide a detailed description, illustration and photographs. Moreover, as phylogenetic relationships revealed that V. flexuosum s.l. is not monophyletic in its actual circumscription, a taxonomic reconsideration of this taxon is suggested.

[Botany • 2023] Cedrela angusticarpa (Meliaceae) • A New Species and a new record for Cedrela in Ecuador: morphological, molecular, and distribution evidence

Cedrela angusticarpa W. Palacios,

in Palacios, Torres, Quintana, Asadobay, Iglesias, Quillupangui, ... et Rivas-Torres, 2023. 

 DOI: doi.org/10.11646/phytotaxa.595.2.1 

 

Abstract

A new Cedrela (Meliaceae) species, Cedrela angusticarpa, is described through a combination of taxonomic, morphological, and molecular analyses. Cedrela kuelapensis, originally described as an endemic species of northern Peru, is also reported here as a new record for Ecuador. Cedrela angusticarpa has oblong or oblong-lanceolate glabrous leaflets, rounded at the base. Inflorescences are up to 70 cm long, and flowers present a cupuliform calyx with five regular teeth. Fruits are narrowly obovoid capsules. Through molecular analyses using nine microsatellite loci, it is evident that samples from C. angusticarpa form their own genetic cluster when compared to the most morphologically similar species, C. odorata, suggesting that they belong to a new separate species. Additionally, here we report that C. angusticarpa has a very narrow geographic range, recorded between 550 and 1300 m in elevation, and restricted to the relatively small areas of northwestern Ecuador. Climatic niche modelling techniques were used as a proxy for assessing potential distributions and habitat loss percentages for both C. angusticarpa and C. kuelapensis. Finally, IUCN Red List categories and criteria were applied to assess the conservation status of both Cedrela species analyzed here.

Cedrela angusticarpa W. Palacios, sp. nov.  

Diagnosis:— Cedrela angusticarpa is related to C. odorata. The distinctive characteristics of these species are: a) leaflets oblong to oblong-lanceolate, base obtuse or rounded, (8–)9–15 × (4–)5–6 (–7) cm in C. angusticarpa vs leaflets oblong, oblong-falcate, base usually strongly asymmetric and rounded on one side, acute or obtuse on the other, 7–14 × 2.5–4 cm in C. odorata; b) inflorescence a robust-erect panicle, 40–70 cm long in C .angusticarpa vs a curved panicle, 15–40 cm long in C. odorata; c) calyx with five teeth in C. angusticarpa vs calyx 2–3-lobed in C. odorata; d) fruits narrowly obovoid, 1.3–1.8 cm in diameter, base acute, sometimes slightly 5-angled when dry in C. angusticarpa vs fruits oblong or ellipsoid, 1.8–2.6 cm in diameter, base rounded or obtuse in C. odorata.

Etymology:—The specific epithet refers to the narrow fruits recorded in this taxon, although the length is equivalent to that of other species.

Lepanthes carrizosana is most similar to Lepanthes darioi Luer & R.Escobar. It can be distinguished by having a pubescent, obovate, bilaminate lip with cuneate connectives (vs. narrowly ovate lip and oblong connectives), and a small appendix with a pair of minute apical lobes that come from a slightly short pubescent, concave base (vs. broadly triangular appendix held directly below the stigma).

Eponymy: The name of the new species honors Julio Carrizosa Umaña, a scientist, environmentalist and thinker with a great vision of the connection between environmental institutionalism and strategies aimed at sustainable development in Colombia. He was the Director of the Institute of Environmental Studies of the National University of Colombia from 1993 to 1998. He currently coordinates the Natural Parks Committee of the Colombian Academy of Exact, Physical, and Natural Sciences. He has been designated a full member of the Colombian Society of Engineers, a full member of the Geographical Society of Colombia, vice president of the Colombian Society of Ecology in 1978, an honorary member of the Cartographic Society of Colombia and the Association of Fisheries Researchers, president of the Environment Committee of the Pan-American Institute of Geography and History between 1973 and 1976, and corresponding member of the Ecuadorian Institute of Natural Resources.

Abstract

A new species, Proaegeria murzini sp. n., is described and illustrated from a series of males and a female collected in the vicinities of Kindia, Guinea. The new species is well distinguished from the closest relative, Proaegeria vouauxi Le Cerf, 1916, by the colouration of the abdomen and the details of the structure of the hindwing. The study of the genital structures of both the male and the female of the new species unequivocally determines the systematic position of this genus in the tribe Sesiini.

Abstract

Most marine shrimp species of the family Palaemonidae are characterized by symbiotic associations with hosts that belong to a wide range of invertebrate phyla. One clade of related endosymbiotic species has evolved to live inside the branchial chambers of ascidians and the mantle cavities of bivalve molluscs. The phylogeny of this clade (comprising 15 bivalve-associated species in the genera Anchistus, Neoanchistus, and Paranchistus, and three species of ascidian-associated species in the genus Dasella) is the topic of the present study, which is based on both morphological and molecular data. A concatenated phylogeny reconstruction was built by using the markers coi and 16S. With the help of a total evidence approach (with a scored morphological datamatrix), species could be added for which no molecular data were available. An ancestral character state analysis was performed to detect host switches. In contrast to another endosymbiotic clade, the ancestral host state was found to be slightly in favour of bivalves. The phylogenetic relevance of morphological features is discussed with a focus on a tympanal organ located in the major chelipeds of some bivalve-associated shrimp species. This little-known anatomical structure is illustrated by sem and µCT scans. Its possible function is discussed. In the phylogeny reconstructions, both Anchistus and Paranchistus were found to be polyphyletic. They were reclassified to obtain a more natural classification: Anchistus custoides and Anchistus custos were transferred to the resurrected genus Ensiger. Paranchistus liui, P. nobilii, P. pycnodontae, and P. spondylis were transferred to Polkamenes gen. nov. Anchistus pectinis and P. ornatus were transferred to Tympanicheles gen. nov. Per genus, a key to the species is provided.

Polkamenes pycnodontae (Bruce, 1978) RMNH.CRUS.D.48261, from Hyotissa hyotis (L., 1758)

 Genus Polkamenes gen. nov.

Etymology. ‘Polkamenes’: named after the characteristic blue-, red-, and orange-dotted pattern seen on the species’ carapace, abdomen, and appendages ‘Polka dots’ (English, in combination with the common palaemonid suffix ‘-menes’; see e.g., Ancylomenes Okuno & Bruce, 2010, Laomenes Clark, 1919, Periclimenes). Gender: masculine.

recognize four species: Polkamenes liui (Li, Bruce & Manning, 2004); Polkamenes nobilii (Holthuis, 1952); Polkamenes pycnodontae (Bruce, 1978); and Polkamenes spondylis (Suzuki, 1971).

Distribution. Shiraiso, Manazura-Machi, Kanagawa Prefecture, Japan, (cf. Suzuki, 1971, Hayashi, 2005, 2006); South China Sea (Li et al., 2004).

  Tympanicheles ornatus (Holthuis, 1952), RMNH.CRUS.D.42794, from Atrina vexillum (Born, 1778) 

Genus Tympanicheles gen. nov.

Etymology. ‘Tympanicheles’: named after the ‘drum-like’ veil on the species’ major chela. Built from ‘Tympani-’, a suffix for drum in Latin (‘Tympanum’), and ‘-cheles’ for claws in Latin. Gender: masculine.

 

  recognize two species: Tympanicheles ornatus (Holthuis, 1952), and Tympanicheles pectinis (Kemp, 1925).
