Scorpions of Ethiopia. Part IV. Genus \u3cem\u3eUroplectes\u3c/em\u3e Peters, 1861(Scorpiones: Buthidae)

All data about the distribution of Uroplectes fischeri (Karsch, 1879) in Ethiopia and Somalia are summarized. U. fischeri is fully illustrated with color photos of habitus and locality. Uroplectoides abyssinicus Lourenço, 1998 is discussed and synonymized with U. fischeri. Genus Uroplectoides Lourenço, 1998 is synonymized with Uroplectes Peters, 1861. Hemispermatophore of U. fischeri was extracted and illustrated for the first time. In addition to morphological analysis we also describe the karyotype of male U. fischeri from Ethiopia (2n=28)

Scorpions of Sri Lanka (Arachnida: Scorpiones). Part III. \u3cem\u3eHeterometrus yaleensis\u3c/em\u3e sp. n. (Scorpionidae)

Heterometrus yaleensis sp. n. from Sri Lanka, Southern Province, Yale National Park is described and compared with other species of the genus. The presence of a unique dorsointernal carina on the pedipalp chela distinguishes H. yaleensis sp. n. from all other Heterometrus species. Additional information is provided on the taxonomy and distribution of the genus Heterometrus in Sri Lanka, fully complemented with color photos of specimens of both sexes of the new species, as well as of their habitat. In addition to external morphology and hemispermatophore, we also describe the karyotype of H. yaleensis sp. n. (2n=99)

Scorpions of Sri Lanka (Scorpiones: Buthidae, Chaerilidae, Scorpionidae) with description of four new species of the genera \u3cem\u3eCharmus\u3c/em\u3e Karsch, 1879 and \u3cem\u3eReddyanus\u3c/em\u3e Vachon, 1972, stat. n.

Data about all 18 known scorpion species of Sri Lanka are summarized. All previously known species were newly collected and four new species discovered during a scorpiological expedition in 2015. Information is provided about their taxonomy, distribution, ecology, and reproductive biology, fully complemented with color photos of live and preserved specimens, as well as their habitat. Subgenus Isometrus (Reddyanus) Vachon, 1972 is elevated to genus level, Reddyanus stat. n., supported by new characters of setation on leg tarsomere II and hemi-spermatophore morphology. Charmus saradieli sp. n., Reddyanus ceylonensis sp. n., R. jayarathnei sp. n., and R. ranawanai sp. n. are described, compared with other species and fully illustrated. Heterometrus serratus (Pocock, 1900) is restored and differentiated from H. indus (Geer, 1778). Charmus minor Lourenço, 2002 is synonymized with Charmus laneus Karsch, 1879; Isometrus garyi Lourenço et Huber, 2002 is synonymized with Reddyanus loebli (Vachon, 1982) comb. n., and Heterometrus spinifer solitarius Couzijn, 1981 is synonymized with Heterometrus indus (Geer, 1778). A key and distribution maps for all 18 Sri Lankan scorpion species are presented. Hemispermatophores of Buthoscorpio sarasinorum (Karsch, 1892), Charmus laneus Karsch, 1879, Isometrus thwaitesi Pocock, 1897, Lychas srilankensis Lourenço, 1997, Reddyanus basilicus (Karsch, 1879) comb. n., R. ceylonensis sp. n., R. loebli comb. n. and Heterometrus gravimanus (Pocock, 1894) are illustrated and described for the first time. In additional to morphological analysis, we also describe the karyotype of Buthoscorpio sarasinorum (2n=14); Charmus laneus (2n=9); Isometrus thwaitesi (2n=8); Lychas srilankensis (2n=16); Reddyanus basilicus comb. n. (2n=15–16); R. ceylonensis sp. n. (2n=16); and R. loebli comb. n. (2n=17). The significance of cytogenetics and hemispermatophore morphology in buthid taxonomy are discussed
