Another web in the wall: A new Pikelinia Mello-Leitão, 1946 (Araneae, Filistatidae) from Colombia, with notes on its diet and description of the female genitalia of P. fasciata (Banks, 1902)

Abstract

The new synanthropic crevice weaver spider species, from the family Filistatidae, Pikelinia floydmuraria sp. nov. (male and females) is described from the department of Tolima, Colombia. The female internal genitalia of P. fasciata from the Galapagos islands, Ecuador, is described here for the first time.

Additional unidentified species of Pikelinia populations were recorded in the departments of Cauca, Quindío, and Risaralda. Dietary analysis of P. floydmuraria sp. nov. (Tolima) and Pikelinia sp.

(Armenia) revealed a predominance of Hymenoptera (~ 35 % of prey), followed by Diptera and Coleoptera. This study expands known diversity and trophic ecology of Pikelinia genus.
