Alisotrichia coclensis does not fit well into any of the species groups outlined by Olah and Flint (2012) , but we tentatively assign it to the orophila group based on the lateral process of abdominal segment VIII bearing a pair of apical spines. The number of these spines varied among the specimens we examined. In some cases there are two on each side, in others there are three on a side, and some have two on one side and three on the other. The new species is most similar to A. cainguas Angrisano and Sganga from Argentina , but differs in lacking a ventromesal process from segment VII and in the antennae having both the scape and the flagellum greatly dilated. Description. Length 1.6–1.8 mm , 18 antennal segments, scape enlarged, pedicel elongate and covered with spatulate hairs, flagellum flattened and expanded, and color brown (in alcohol). Male genitalia. Abdominal segment VII annular, lacking a ventromesal process. Segment VIII expanded into posteromesal process, which bears 2-3 elongate spines, dorsolaterally with a short process bearing elongate thickened seta; in ventral view, the spines originate from lateral lobes; in dorsal view, segment VIII is produced anteriorly into a pair of finger-like processes, each bearing an elongate, thickened seta. Segment IX divided posteriorly, dorsal portion narrow and elongate, ventral portion rectanguloid, with a thin coiled process from upper surface, which curves downward distally, anteriorly narrowing to an elongate apodeme; in dorsal view rectanguloid, bilobed apically, laterally with elongate spines. Segment X a thin lobe in lateral view, dorsally short, rounded apically. Phallus tubular, narrowing at midlength, posterior margins rounded and lightly sclerotized, ejaculatory duct narrow protruding distally as small lobe. Female and larva. Unknown. Type material. Holotype male.
