Diagnosis: This is the sole species of Western Hemisphere’s Dilasiathat lacks secondary sexual characters (grouping of copulatory teeth, teeth on the inner margin of foretibiae and on foretrochanters) in male. Description: Measurements, see Table IV. The sole specimen was not measured because it was mounted on a slide. Male:Dorsal view: General coloration dark brown with extreme base of corion, little spot on the inner margin of cuneal fracture, labium and legs, paler. Setae short and suberected dorsally. Head: Smooth, short; eyes large, interocular space 1.5x the width of one eye ( Fig. 73); antennal segment II thick and shorter than head. Thorax: Pronotum small, with lateral margins straight; anterior margins not rounded, posterior margin slightly concave; anterior lobe smooth, posterior lobe rugose. Mesosternum and metasternum not sulcate medially; the latter prolonged posteriorly ( Fig. 75). Foretibiae armed with a few long and thick setae on inner margin; forefemora unarmed, pads vestigial ( Fig. 74). Hemelytra smooth. Abdomen: Hairs on dorsal surface short and restricted to outer margins. Pygophore ( Fig. 76) with characteristic punctures on dorsal, central and subapical areas. Genitalia with left paramere short, slightly sinuate, widened subapically and apically acute ( Fig. 78). Aedeagus armed with two lateral and subapical feather-like structures ( Fig. 77). Female:Unknown. Distribution: Peru. ( Fig. 48) Materialexamined: Holotype PERU: ♂ Cusco, San Martin2, Base Pluspetrol, (at light) II-2006, J. Williams, 72º46’53’’W– 11º46’17’’S, (slide-mounted). MACN. Etymology: The specific name refers to the Peruvian department where this specimen was collected. Discussion. This species is close related to the D. galateaegroup, but differs in the shape of left paramere, by the absence of teeth or spines on the inner margin of the foretibiae, and by the presence of vestigial pads.
