Tetragnathid spiders from Sri Lanka: description of two new species (Araneae: Tetragnathidae)

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.
