Olios

Olios argelasius, copyright Ferran Turmo Gort.

Belongs within: Sparassidae.

The genus Olios has long been used for a poorly defined assemblage of smaller huntsman spiders; the description given below refers to a more restricted grouping, but many species of uncertain affinities remain in the genus (Jäger & Kunz 2005).

Characters (from Jäger & Kunz 2005): Eye field relatively wide, eyes subequal; chelicerae with one or two anterior teeth, three to six distinctly separated posterior teeth, anterior and posterior teeth of similar size, cheliceral furrow without denticles; male embolus with characteristic distal coil, the latter often with appendage at base, tegular apophysis often present; female epigyne usually with longitudinal slit, slit rarely absent with only small part of median septum visible in posterior half of epigyne, anterior part of internal duct system membranous or little sclerotised.
