Diagnostic description
Habitus: Fig.20 View Figs 19–24 .Wingless.Body length: 10.6–11.5mm.Body colour variable,from brunneous to brownish black; femora and tibiae brownish; tarsi, antennae and mouthparts reddish brown. Elytral microsculpture transverse, weakly impressed. Head moderately broad, constricted basally, eyes moderately bulging, genae flat. Pronotum subcordiform, transverse, sides arcuate anterad, markedly sinuate posterad; hind angles slightly obtuse or almost right angled; two pairs of lateral setae. Elytra elongate-ovoid, slightly convex; striae entire, well impressed; intervals variable, flat to slightly convex in basal half, convex at apex. Third elytral interval with three setae. Last visible abdominal ventrite with two pairs (♂) or four pairs (♀) of setae along its apical margin. Legs: tarsi smooth dorsally, metatarsomeres 1–3 bisulcate, fourth metatarsomere with one pair of dorsolateral subapical setae, apical lobes moderately long, the external lobe 1.5 times longer than the inner lobe; fifth metatarsomere convex dorsally, asetose ventrally. Male genitalia: Fig. 23 View Figs 19–24 . Median lobe weakly arcuate, apex short, acute, endophallus without sclerotized structure. Female genitalia: unstudied.
Comparisons
Dyscolus sulcipedis Moret sp. nov. belongs to the marini clade along with D. marini Moret sp. nov., D. ruizi Moret sp. nov., D. arborarius Moret sp. nov., D. moretianus and D. rugitarsis Moret sp. nov. Based on external morphology (not on molecular data), its closest relative is D. rugitarsis Moret sp. nov., from which it differs mainly in the following characters: elytral microsculpture transverse, weakly impressed (coarser and mostly isodiametric in D. rugitarsis Moret sp. nov.); head slightly narrower; latero-posterior sinuation of the pronotum deeper; last visible abdominal ventrite with two pairs (♂) or four pairs (♀) of apical setae (one and two pairs in D. rugitarsis Moret sp. nov.); tarsi not rugose; fifth metatarsomere plesiomorphic, not broadened and dorsally depressed.
Habitat
Upper montane forest, at around 3240 m a.s.l. Active at the beginning of the night on the surface of the leaf litter and on tree trunks 2 m above ground.
Geographic distribution
Only known from the type locality in Southern Ecuador, in Parque Nacional Yacuri. Probably microendemic.
