Genus Lagnus L. Koch, 1879

Description. Medium sized spiders. Chelicera with two promarginal teeth and one fissident retromarginal tooth of multiple cusps. Legs, especially in males, extremely elongate and spiny, with first tibia having more than seven pairs of ventral macrosetae and first metatarsus having more than five pairs of ventral macrosetae. Male palp elongate; embolus slender and coiled for about half a circle; proximal tegular lobe and ventral tibial bump absent; retrolateral sperm duct loop wide. Epigynal window present with a median septum. Vulva with relatively short copulatory duct and only one pair of spermathecae. Lagnus can be easily distinguished from other euophryine genera by the elongate, slender and spiny legs especially in male, and the elongate male plap.

Remarks. Two species have been recorded from Fiji ( Platnick 2012). Another new species from Philippines is described here.
