Body colour variable, from brunneous to brownish black; femora brownish; rest of the legs, antennae and mouthparts reddish brown. Elytral microsculpture variable, mostly isodiametric in the middle part of the intervals, oblong near the striae. Head broad, weakly constricted basally, eyes moderately bulging, genae flat. Pronotum transverse, sides slightly arcuate anterad, weakly sinuate posterad; hind angles obtuse; two pairs of lateral setae. Elytra ovoid, slightly convex; striae entire, well impressed, relatively broad; intervals variable, flat to slightly Figs 19–24. Dyscolus spp., habitus (19–21) and aedeagus, median lobe in lateral view (22–24). 19 . D. rugitarsis Moret sp. nov. , male holotype (QACZ). 20 . D. sulcipedis Moret sp. nov. , male holotype (QACZ). 21 . D. marini Moret sp. nov. , female paratype. 22 . D. rugitarsis Moret sp. nov. 23 . D. sulcipedis Moret sp. nov. 24. D. marini Moret sp. nov. convex. Third elytral interval with 2–3 setae (two specimens lack the anterior seta on one elytron only). Last visible abdominal ventrite with one pair (♂) or two pairs ( ♀ ) of setae along its apical margin. Legs: tarsi rugose dorsally, metatarsomeres 1–4 bisulcate, fourth metatarsomere with one pair of dorsolateral subapical setae, apical lobes moderately long, the external lobe two times longer than the inner lobe; fifth metatarsomere broadened and dorsally depressed in basal half, ventrally asetose. Male genitalia : Fig. 22 . Median lobe arcuate, apex relatively large, very thin in lateral view, endophallus with one subapical sclerotized structure. Female genitalia : unstudied. Comparisons Dyscolus rugitarsis Moret sp. nov. is closely related, within the D. marini Moret sp. nov. clade, to D. moretianus which inhabits the western part of the Loja Province in the Parque Podocarpus, 70 km northwest from the type locality of this new species. Dyscolus rugitarsis Moret sp. nov. differs from the latter by the blunter hind angles of the pronotum, the presence of at least one seta in the basal half of the third elytral interval (third interval asetose in D. moretianus ), slightly longer antennae and tarsi, and a markedly longer external lobe at the apex of the fourth metatarsomere. For comparison with D. sulcipedis Moret sp. nov. , see below (p. 27). Habitat Upper montane forest, at around 3200–3250 m a.s.l. Active at the beginning of the night on the surface of the leaf litter. Geographic distribution Only known from the type locality in Southern Ecuador , in Parque Nacional Yacuri. Probably microendemic.
