Type materialHolotype (only known specimen)
ECUADOR • ♂; Loja Province, Parque Nacional Podocarpus, Cajanuma, Waypoint 392; 4°6′58.4″ S, 79°10′18.6″ W; 2850 m a.s.l.; 17 Mar. 2015; P. Moret and C. Ruiz leg.; COI voucher PM392-09, BOLD sequence SUM059-18; MNHN.
Diagnostic descriptionHabitus: Fig. 32. Wingless. Body length: 9.3–9.6 mm. Head, pronotum and elytra brunneopiceous; legs, antennae and mouthparts reddish brown. Elytral microsculpture isodiametric. Head convex, markedly constricted basally, eyes small, not bulging, genae almost flat in dorsal view, as long as the eyes. Pronotum elongate, convex; sides weakly arcuate anterad, almost straight in basal fourth, with a very short sinuation at level of the basal seta, hind angles obtuse and blunt, anterior angles pronounced, broadly rounded; two pairs of lateral setae. Elytra elongate, subparallel; base relatively narrow, shoulders rounded; sides arcuate apically without subapical sinuation; striae entire, well impressed, not punctate; intervals slightly convex. Third elytral interval asetose. Legs rather short, meso- and metatarsomeres 1–3 with a lateral sulcus on each side; fourth metatarsomere with one pair of dorsolateral subapical setae, its apical lobes very short, the outer lobe twice as large as the inner lobe; fifth metatarsomere asetose ventrally. Last visible abdominal ventrite of the male with one pair of setae along its apical margin. Male genitalia: Fig. 33. Median lobe almost straight in its basal half, shortly arcuate before apex; apex slightly reflexed upward, narrow and acute in lateral view; endophallus without sclerotized structure. Female genitalia: unknown.
ComparisonsClosely related to D. moreti Perrault, 1993, but smaller (most specimens of D. moreti range from 10 to 11 mm), the lateral margin of the pronotum narrower, the elytra narrower and less convex, the apex of the aedeagus shorter, more acute, and not bent ventrally as in D. moreti.
HabitatUpper montane forest on the Eastern slope of the Andes, at around 2850 m a.s.l.
Geographic distributionOnly known from the type locality in Southern Ecuador. Probably microendemic.
