A New Species

The skittering frog genus Euphlyctis is known to have a distribution range from Arabian Peninsula to Bangladesh through India and Sri Lanka. Although species descriptions were initiated about two centuries ago in the genus with a small number of species described, taxonomic identities and genetic information for many species are still incomplete / inaccurate. Here, we report the systematic status of this group, discuss a series of taxonomic issues, and describe a new species. Based on morphological characters and colour patterns, and their reciprocal monophyly in the molecular tree, two morphological groups, ‘cyanophlyctis group’ and ‘hexadactylus group’ are established within the genus Euphlyctis. We discuss the genetic identity for E. cyanophlyctis, described 220 years ago from the Indian subcontinent, from the surroundings of its type locality. E. mudigere is proposed as a junior synonym of E. cyanophlyctis as it was described from populations here considered to originate from the general distribution area of the latter taxon, and without substantial genetic divergence from other populations here attributed to E. cyanophlyctis. The potential of resurrection of Euphlyctis seistanica due to distinct genetic population in Iran is discussed; this lineage appears to be genetically rather similar to E. kalasgramensis, and the species distinctness of these two lineages requires further study. The validity of E. kalasgramensis is also discussed in the context of the historically earlier nomina, Rana bengalensis and Rana leschenaultii due to distribution range overlaps. The prospects of establishing either Rana cyanophlictis variety fulvus or Rana cyanophlictis variety flavens from Sri Lanka are also mentioned. Based on a comparative account, we report the discovery of a new species of skittering frog Euphlyctis kerala sp. nov. which has a restricted distribution in the western coastal plains of India, south of the Palghat gap.

A New Species

Our integrated evidence indicates morphological and genetic polymorphisms in Allium cyathophorum and thus the need for a taxonomic revision. First, A. cyathophorum var. farreri is reinstated as A. farreri. Second, a cryptic allotetraploid population geographically confined to the intermediate zone between A. cyathophorum and A. farreri is described here as a new species named A. tetraploideum. Morphological characters that differentiate these three species from each other, as well as information on their distribution range and habitat, are provided.

The paper describes a new frog of the genus Nannophrys from Sri Lanka. The new species is distinguished from all other Nannophrys species by the following combination of morphological characters; distal subarticular tubercle and penultimate subarticular tubercles of 4th toe are well separated (vs. these two tubercles close in all other species of the genus). Supernumerary tubercle absent or smaller than penultimate subarticular tubercle on 4th toe. A hard sharp narrow symphysial knob and close pair of sharp apophyses on anterior edge of mandible and symphysial knob lower than two apophyses (vs. all other species with a blunt wider symphysial knob and wider pair of apophyes on anterior edge of mandible, and symphysial knob of same height or higher than two apophyses. Palmar tubercles comparatively smaller, inner palmar tubercle separated from outer palmar tubercle (vs. other relatives possess palmar tubercles comparatively large, inner palmar tubercle connected with outer palmar tubercle). Ecological and distributional notes for the new species are given.

A New Species

Spathacanthus is a Mesoamerican genus that occurs in tropical and temperate regions from southern Mexico to Costa Rica; its taxonomy has not been updated for two decades. In view of the fact that a new species has been discovered and that the interspecific affinities in this genus have not been addressed to date, the present study aims to revise the genus Spathacanthus. Specimens of plants of this genus collected from across the distribution range and deposited in herbaria and digital databases were reviewed. In parallel, a cladistic analysis was carried out, based on morphological characters in order to examine relationships between species. Four species of Spathacanthus were recognised: one endemic to Costa Rica, another micro-endemic to Veracruz in Mexico, one more restricted to the forests of Mexico and Guatemala and the last one more widely distributed. Reflecting the previously limited knowledge of the group, many of the specimens that we studied had been misidentified. A key to differentiate these species is provided, supplemented with photographs, drawings and other illustrations, morphological descriptions, synonymy and ecological data. Results, presented here, extend the distribution range of some taxa and a distribution map is presented. The cladistic analysis recovered the genus as monophyletic, showing that S. hoffmannii and S. hahnianus are sister taxa and S. magdalenae was found to be more closely related to S. parviflorus. These plants are vulnerable to degradation and habitat loss.

A New Species

Background and Aims: In Mexico, Coulteria is a morphologically diverse genus, having many endemic species in the country. Despite its diversity, species delimitation and circumscription are not fully documented. Botanical explorations in central Mexico during the last 25 years have resulted in the discovery of several new legume taxa in the Río Balsas Depression. A new species of Coulteria from the Western Río Balsas Depression is here described and illustrated.Methods: During fieldwork, morphological studies and electron microscopy analysis of the already species described of Coulteria, we detected a new species in the Infiernillo area of Guerrero and Michoacán, Mexico. For the new species, we estimated its conservation status based on extent of occurrence (EOO) and its area of occupancy (AOO) using the GeoCAT software, applying the categories and criteria of the IUCN Red List.Key results: Coulteria delgadoana, a new species of Caesalpinioideae endemic to the seasonally dry forest of Guerrero and Michoacán (Western Río Balsas Depression), Mexico, is described and illustrated based on morphological evidence. Coulteria delgadoana has long male inflorescences up to 15 cm long, small flowers, leaves with glabrous leaflets and prominent reticulate venation, and a glabrous chestnut brown fruit with purplish tints. Based on IUCN criteria, we suggest an Endangered (EN) category of the species.Conclusions: Morphological characters of the new species C. delgadoana, suggest that it is similar to C. glabra, a species from Colima and Jalisco. The long size of the male inflorescence has not been observed in other Coulteria species. Coulteria delgadoana shares its distribution area with C. lewisii in Infiernillo.

A New Species

The supraspecific taxonomy of the coastal carabid Bembidion (‘Cillenus’) complex is controversial because a single ‘synapomorphy,’ a large head with long mandibles, may be the result of functional convergence. This study examined the phylogeny of B. (‘Cillenus’) complex based on morphological characters to revise the complicated taxonomy of this group. All type species of the genera concerned were included, and membranous parts of the genitalia (male endophallus and female vagina and spermatheca) were examined for the first time. Because all species are treated under the genus Bembidion Latreille (s. l.), Bembidion umi nom. nov. is proposed as a new name for Sakagutia marina Uéno. In the resultant tree, reciprocal monophyly of most traditional taxa was not supported, whereas a monophyletic group of the following seven species was relatively well supported: B. seticorne Lindroth, B. yokohamae (Bates), B. sumaoi Morita, B. aestuarii (Uéno & Habu), B. tokunoshimanum (Nakane), B. tsutsuii (Uéno), and B. yakushimanum sp. nov. Based on these results, the subgenus Desarmatocillenus Netolitzky (type species: B. yokohamae) was redefined, and two subgenera were synonymised with it: Novicillenus Uéno & Habu (type species: B. aestuarii) syn. nov., and Corallicillenus Uéno (type species: B. tsutsuii) syn. nov.. Bembidion (Desarmatocillenus) yakushimanum sp. nov. is described from Japan.
