Atopsyche (Atopsaura) hamata Ross & King 1952

Atopsyche hamata Ross & King 1952 , 202 (Type locality: Brazil, Summit of Mt. Roraima; holotype depository: AMNH; male). Atopsyche (Atopsaura) hamata Ross & King ; Ross 1953, 292, type species of subgenus Atopsyche (Atopsaura) ; Paprocki et al. 2004, 7 (checklist).

Diagnosis. This species belongs to the Atopsyche (Atopsaura) longipennis Group. It is closely similar to A. longipennis in that the filipods are about as long as the parapods and the apicomesal portion of the first article of each inferior appendage is about as long as the second article of the same appendage and completely overlapped by it ( Ross & King 1952). Atopsyche hamata also resembles A. antisuya in the apical portion of the first article and in the second article of an inferior appendage, but differs in that the first article is curved caudoventrad in A. hamata .

Description. Parapods simple, each widest at center, a single small dorsal tooth near apex. Filipods sinuate, about as long as parapods. Inferior appendages each with first article cylindrical, curved and mesal apex prolonged into fingerlike tip; second article as long as, and completely overlapping prolongation of first. Principal lobes (“beaks” of Schmid 1989) of phallic apparatus each bearing short, sclerotized spine on its posteroventral angle and long, petiolate membranous process (endotheca) on its posterodorsal angle, this process more than 1/3rd as long as entire phallotheca, bearing short spine basoventrally resembling and perpendicular to those borne ventrally on principal lobes and smaller spines and setae on apical third of process; aedeagus L-shaped ( Ross & King 1952).

Material examined. None.

Distribution. Brazil (Roraima).
