Abstract

A conchological revision is given of the Enidae of Pakistan and India, mainly based on material collected in Pakistan by Kurt Auffenberg and others (stored in the Florida Museum of Natural History) and on historical shell material collected by British explorers in former British India (as stored in The Natural History Museum, London and the University Museum of Zoology, Cambridge). In total, 39 species are described and figured; of these 39 species the identity of only two remains unknown because no material was available (Bulimus eous Reeve, 1850 and Buliminus (Petraeus) stoliczkanus G. Nevill, 1878), and 10 are new to science. For the preoccupied name Coccoderma von Möllendorff, 1901 the new name Coccogranula gen. nov. is introduced. Coccogranula panos, previously known from Sri Lanka only, is reported for the first time in India (Salem Hills). From India, 19 species are reported, including one new species: Pseudonapaeus huttonianus spec. nov. From Pakistan, also 19 species are reported, of which 8 species turned out to be new: Mirus bensoni spec. nov., Pseudonapaeus dominoides spec. nov., P. chitralensis spec. nov., P. ziczac spec. nov., P. preecei spec. nov., P. ziaratensis spec. nov., P. theobaldianus spec. nov. and Geminula abletti spec. nov. The taxon Bulimus segregatus Reeve, 1849 is assigned to Turanena Lindholm, 1922; it is the first report for this genus in India. Zebrina (Subzebrinus) drangiana Jaeckel, 1956, recorded for the first time from Pakistan, is assigned to the genus Triangustoma Schileyko, 1984, being the second species of this previously monotypic genus. A few scattered samples from Afghanistan are discussed belonging to nine species; one of them is described as new (Pseudonapaeus dubius spec. nov.). Part of the Afghanistan Enidae samples reported by Likharev & Starobogatov (1967, Trudy Zool. Inst. Akad. Nauk SSSR, 42) and stored in St. Petersburg in the Zoological Institute of Russian Academy of Sciences are now figured. It turned out that some of their determinations (Subzebrina eremita, S. potaninianus, S. sogdianus and S. rufistrigatus) need to be reconsidered: they likely belong to four undescribed species.

Two new species of Hecuba Schumacher, 1817 (Bivalvia: Donacidae)

Author: J.G.M. (Han) Raven
Basteria, 88 (1): 1-5

Abstract

In addition to the three extant species of Hecuba Schumacher, 1817 discussed in Raven & Dekker (2022, Basteria, 86 (2): 96-113) a fourth extant species occurs in eastern Sumatra, Indonesia, herein described as Hecuba parva spec. nov. A fossil from the Miocene of India is herein described as H. mukerjeei spec. nov. The type species of Hecuba is corrected to Venus scortum Linnaeus, 1758. A correction is made regarding the reference to Rumphius in Raven & Dekker (2022).

The families Streptaxidae and Diapheridae (Gastropoda, Pulmonata) in Bhutan, with notes on some species occurring in Nepal and North-east India

Authors: Edmund Gittenberger, Pema Leda, Sherub Sherub, Choki Gyeltshen
Basteria, 85 (1): 73-81

Abstract

The sister-families Streptaxidae and Diapheridae are reported from eastern Bhutan, with two and four species, respectively. The occurrence of the streptaxid Perrottetia theobaldi marks the northwestern limit of the genus Perrottetia. Gulella (Huttonella) bicolor is a widespread invasive species that might have its native range in Asia. Two of the four Sinoennea species that are reported from Bhutan, viz. Sinoennea bhucylindrica Gittenberger & Leda and Sinoennea nimai Gittenberger & Gyeltshen, are regarded as new to science. Perrottetia theobaldi, Sinoennea vara and maybe S. latens support the biogeographical link across the Brahmaputra between eastern Bhutan and the Khasi Hills in the Meghalaya state of India. Notes on three Sinoennea species occurring in the eastern Himalayan foothills, but not known from Bhutan, are added.
