  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.

TETRAGNATHID SPIDERS FROM SRI LANKA: DESCRIPTION OF TWO NEW SPECIES (ARANEAE: TETRAGNATHIDAE)


Abstract  
Recent collecting in Sri Lanka has revealed a rich native tetragnathid spider fauna with several new species. In this paper, I describe two new, endemic, species, namely Leucauge rubromaculata sp. nov. and Glenognatha dubiosa sp. nov. from the Sabaragamuwa, Western and North Western Provinces. Leucauge rubromaculata sp. nov. can be separated from all known species of Leucauge of Sri Lanka by its smaller body size, oval abdomen, and presence of two large silver guanine patches anterior and posterior to the spinnerets. Glenognatha dubiosa sp. nov. is similar to G. dentata (Zhu & Wen, 1978), but can be separated from it by having a serrated embolus. Furthermore, G. dubiosa sp. nov. can be separated from all known species of Glenognatha Simon, 1887 by the serrated tip of the conductor. This species constitutes the first record of Glenognatha from Sri Lanka. Finally, Leucauge lamperti Strand, 1907 is considered as nomen dubium.
