Type material

Holotype (only known specimen)

ECUADOR • ♂; Loja Province, Parque Nacional Yacuri, Waypoint 170; 4.781387º S, 79.386938º W; 2870 m a.s.l.; 4 Aug. 2016; P. Moret and S. Aguirre leg.; COI voucher PM170-01, BOLD sequence SUM190-18; MNHN.

Diagnostic description

Habitus: Fig. 17 . Wingless. Body length: 12.8 mm. Body entirely black; femora and tibiae nigropiceous, tarsi and palpi reddish brown; antennomeres 1–4 nigropiceous with the base and the apex testaceous, antennomeres 5–11 reddish brown. Elytral microsculpture transverse. Head small, distinctly constricted basally; frons with two broad round depressions close to the anterior supraorbital seta; eyes convex and prominent, genae long, slightly convex; mandibles long, acutely ended. Pronotum cordiform, slightly broader than long; sides feebly arcuate apically, sinuate basally; hind angles rounded; two pairs of lateral setae. Elytra elongate-oval, base very narrow, humeri completely effaced; striae weakly impressed, subpunctate, intervals slightly convex near apex; subapical sinuation obsolete. Third elytral interval without discal setae. Last visible abdominal ventrite of the male with three pairs of setae along its apical margin. Legs slender, fourth metatarsomere with one pair of subapical dorsolateral setae, apical lobes asymmetrical with a big outer lobe and no inner lobe. Male genitalia: Fig. 18 . Median lobe arcuate in its basal half, then straight (in lateral view), apex short and blunt, endophallus with seven denticles in a small, slightly sclerotized subapical structure. Female genitalia: unknown.

Comparisons

This species shares with D. caulatus Moret, 1993 the general form of the body and the absence of setae on the third interval of the elytra, but D. caulatus lacks the anterior supraorbital seta and the posterior pronotal seta, and has a conspicuous foveate elytral pattern.

Habitat

Upper montane forest on the Eastern slope of the Andes , at around 2870 m a.s.l. Collected by pyrethrin insecticide fogging on mossy branches and epiphytes, two meters above ground.

Geographic distribution

Only known from the type locality in Southern Ecuador, in Parque Nacional Yacuri. Probably microendemic.
