Eurygarka sp.

( Figs. 3 A‑3F)

New record for the genus(determined by D. Cordeiro): BRAZIL, Rondônia, Cacaulândia, 200 km SSE of Porto Velho , 22-31.x. 97, 140 masl, 10°18.0′S, 62°52.1′W, col. W.J. Hanson (LACMENT 268194).

Remarks: This female specimen is undoubtfully an Eurygarka for the following characters: eye bridge with four rows of facets, divided by one facet diameter; palp segments two and three slightly swollen; palp segments 1-3 each with transverse, ovoid sensory organ placed mid-length on their lateral surface; first palp segment a little greater than ½ the length of second, distal three palp segments slightly increasing in length; female cerci short; hypovalvae with single median protuberance, digitiform ( Curler & Moulton, 2008).

This is the first record of this genus to Brazil. This is possibly the female of Eurygarka freyrei Jezek et al., 2011 (described from Bolivia), but its morphology is also similar to the male of E. cyphostylus Curler, 2008 (from the USA), so the association is dubious. The characters that link this female to the males of these two species are: distance of eyes, number of facet rows, the shape of frons groups of setae, the shape of palpus, the shape of Sc vein on the wing and infuscation of costal cell.
