Diagnostic description
Habitus: Fig. 5 View Figs 3–6. 3–4 . Wingless. Body length: 10.2–12.2 mm. Shiny, piceous black with a faint metallic lustre on the elytra, varying from dark green to copper or pink; legs dark brown, antennae and mouthparts reddish brown to brownish. Elytral microsculpture transverse, shallowly impressed. Head broad, convex, eyes bulging, mandibles long and acute. Pronotum convex, rounded, much narrower at base than at apex, not sinuate, hind angles very obtuse, almost rounded; two pairs of lateral setae. Elytra elongate, convex, base narrow, humeri effaced; striae shallowly impressed, finely punctate, intervals flat to subconvex; third interval with three setae, except one male paratype that bears five setae on each side; subapical sinuation deep; apical extension triangular, recurved dorsally, more or less acute at apex. Last visible abdominal ventrite with one pair (♂) or two pairs (♀) of setae along its apical margin. Legs moderately slender; fourth metatarsomere without subapical dorsolateral setae, apical lobes parallel, the outer lobe 1.9 times longer than the inner lobe. Male genitalia: Fig. 6 View Figs 3–6. 3–4 . Median lobe swollen in its middle part, abruptly bent ventrally in distal fourth; apical blade long and sinuate in lateral view; endophallus without sclerotized structure. Female genitalia: unstudied.
Comparisons
Metallic coloration and apically subspinose elytra separate D. giselae Moret sp. nov. from all the species (previously placed in the subgenus Hydrodyscolus ) which share the derived character of a dorsally asetose fourth metatarsomere.
Habitat
Riparian in the montane forest on the Western slope of the Andes , at around 1800–2000 m a.s.l.
Geographic distribution
Southern end of the Chocó biogeographic region in northwestern Ecuador. Only known from the type locality, probably microendemic.
