  A new species of the mygalomorph spider genus Euagrus Ausserer (Araneae: Euagridae) from central Mexico and new records of E. gus Coyle from Tlaxcala Abstract  A new species of the spider genus Euagrus Ausserer, 1875 from temperate pine-oak forests in the states of Tlaxcala and Hidalgo, Mexico is described: E. pulque sp. nov. The description of the new species is based on male and female adult specimens. Additionally, Euagrus gus Coyle, 1988 is recorded for the very first time in the state of Tlaxcala. These species have sympatric distributions in La Malinche National Park, Tlaxcala. With this description, the diversity of the genus increases to 23 species, with Mexico harboring the highest diversity with 17 described species.  Valdez-Mondragón, A., Salinas-Velasco, H.

On the taxonomic validity of Indian ground spiders: VI. Genera Ladissa Simon, 1907, Melicymnis Simon, 1885, and Poecilochroa Westring, 1874 (Araneae: Gnaphosidae)

Abstract

Indian species of the genera Ladissa Simon, 1907, Melicymnis Simon, 1885, and Poecilochroa Westring, 1874 are reviewed. The species Ladissa latecingulata Simon, 1907, and Melicymnis bicolor Simon, 1885 are considered as species inquirenda due to the immature stage of the types. The type locality of L. latecingulata is confirmed as in Pakistan, and its record in India is found incorrect. The following new combinations are recognised: Hitobia behni (Thorell, 1891) comb. nov., H. devendrai (Gajbe & Rane, 1985) comb. nov. and H. tikaderi (Patel, 1989) comb. nov. (all ex. Poecilochroa). Images of all the examined type specimens, and supplementary descriptions for P. barmani, H. behni comb. nov. and H. devendrai comb. nov. are presented.
