Type material.
Holotype: Ecuador • ♂; Pichincha, Bellavista Cloud Forest Reserve and Lodge, small stream ; 00.01212°S, 078.68958°W; 13 July 2017; el. 2614 m; Andrea Tapia leg.; pan trap; in alcohol; UMSP 000560013 View Materials ; UMSP GoogleMaps . Paratypes: Ecuador • 1 ♂ and 1 ♀; same collection data as for holotype; 15 July 2017; in alcohol; UMSP 000560011 View Materials ; MECN GoogleMaps .
Diagnosis.
Rhyacopsyche bellavista , new species, is most similar to R. rhamphisa Wasmund & Holzenthal, 2007 ; both species have a slender inferior appendage that curves dorsad and terminates in a strongly sclerotized apex that points mesally. The inferior appendage curves much more strongly in R. bellavista than it does in R. rhamphisa . The general appearance of tergum X in R. bellavista , large and bearing apical spines and spicules apically, can also be used to diagnose R. bellavista .
Description.
Adult (male: n = 2, female: n = 1). Forewing length 3.8–3.9 mm (male); 3.9 mm (female). Head unmodified, with 3 ocelli; antennae unmodified. Tibial spurs 1, 3, 4. Specimens brown in alcohol. Sternum VII with short mesoventral point. Male genitalia. Abdominal segment IX setose, anterolateral margin rounded, posterolateral margin short, straight; dorsolateral lobe of segment IX large, straight, directed slightly dorsad, bearing dark, peg-like setae, in dorsal view deeply and broadly divided, slender (Fig. 2 A, B View Figure 2 ). Tergum X membranous, partially retracted inside segment IX; apex large, extending past both dorsolateral lobe of segment IX and inferior appendage, with spines and spicules apically; in dorsal view, slender (Fig. 2 A, B View Figure 2 ). Intermediate appendage not apparent. Inferior appendage broadest basally, simple, elongate, slender, curving strongly dorsad; apex strongly sclerotized, pointed, bent mesad (Fig. 2 A, C View Figure 2 ). Phallus basally tubular, elongate, apex membranous; central tubule pointed; lateral process not apparent (Fig. 2 D View Figure 2 ).
Etymology.
Named for the reserve where the type specimens were collected.
Distribution.
