Type material Holotype ECUADOR • ♀ ; Zamora-Chinchipe Province , Parque Nacional Podocarpus , Estación El Colibrí ; 3°59′16.1″ S , 79°5′39.0″ W ; 2110 m a.s.l. ; 18 Mar. 2015 ; P. Moret and C. Ruiz leg.; by night 19.30– 21 pm; on the ground; QCAZ . Paratype ECUADOR • 1 ♀ ; same collection data as for holotype; COI voucher PM402-03, BOLD sequence SUM188-18; CPM . Diagnostic description Habitus: Fig. 29 . Wingless. Body length: 10.6 mm ( paratype ) to 11.3 mm ( holotype ). Head and pronotum black, elytra nigropiceous; legs, antennae and mouthparts brownish to reddish brown. Dorsal integuments shiny, elytral microsculpture transverse. Head relatively small, elongate, eyes prominent, genae long, almost flat. Pronotum cordiform; sides markedly sinuate basally, hind angles obtuse and sharp; laterobasal impressions deep, lateral margins reflexed; two pairs of lateral setae. Elytra oval, convex; striae entire, shallowly impressed, distinctly punctate; intervals flat; preapical sinuation weakly marked. Third elytral interval without discal setae. Last visible abdominal ventrite with two pairs of setae along its apical margin. Legs moderately slender, all tarsi densely pubescent ventrally; metatarsomeres 1–3 bisulcate; external lobe of the fourth metatarsomere 2.5 times longer than inner lobe; fifth metatarsomere asetose ventrally. Male unknown. Female genitalia : unstudied. Comparisons This species belongs to the same clade as D. ravidus Moret sp. nov. Both have the same general aspect and share the character of an asetose third interval, but in D. crespoae Moret sp. nov. the dorsal surface is shiny with a transverse microsculpture on the elytra, the elytra are more convex, the hind angles of Figs 29–31. 29. Dyscolus crespoae Moret sp. nov. , habitus of the female holotype (QACZ). 30– 31 . D. ravidus Moret sp. nov. 30 . Habitus of the male holotype (QACZ). 31 . Aedeagus, median lobe in lateral view. the pronotum more obtuse, the ventral pubescence of the tarsi denser, the apical lobes of the fourth metatarsomere more asymmetrical. Habitat Montane forest on the Eastern slope of the Andes , at around 2100 m a.s.l. Active at the beginning of the night (7.30–9 pm) on the surface of the leaf litter above ground. Geographic distribution Only known from the type locality in Southern Ecuador , in the Parque Nacional Podocarpus. Probably microendemic.
