Type material Holotype ECUADOR • ♂ ; Napo Province , Guamaní , Paso de la Virgen , Waypoint 283 ; 0°21′0.6″ S , 78°11′52.4″ W ; 3890 m a.s.l. ; 11 Mar. 2017 ; P. Moret and M. Gobbi leg.; QCAZ . Paratypes (2 ♂♂, 1 ♀ ) ECUADOR • 1 ♂ ; same collection data as for holotype; MNHN • 1 ♂ ; same collection data as for holotype; CPM • 1 ♀ ; same collection data as for holotype; COI voucher in ethanol PM283-01, BOLD sequence SUM239-18; CPM . Diagnostic description Habitus: Fig. 37 . Wingless. Body length: 9.6–10.9 mm , bigger than D. placitus Moret sp. nov. Ventral surface paler, abdominal ventrites entirely reddish-testaceous. Elytral microsculpture slightly less transverse. Head bigger, genae slightly but distinctly convex in dorsal view (flat in D. placitus Moret sp. nov. ); apex of the labrum bisinuate (straight in D. placitus Moret sp. nov. ); mandibles much longer, finely acute at apex (length of the right mandible / width of the frons between the anterior setae = 0.95 in D. piscator Moret sp. nov. , 1.21 in D. placitus Moret sp. nov. ). Third elytral interval with 3–4 setae, fifth interval with 2–4 setae, seventh interval with 0–1 seta; 11–13 umbilicate setae along the lateral margin ( 17–20 in D. placitus Moret sp. nov. ). Male genitalia : Fig. 40 . Apex of the median lobe slightly curved, not strongly bent downwards as in D. placitus Moret sp. nov. , with a rounded tip, not hooked as in D. placitus Moret sp. nov. Habitat Riparian in the upper montane forest with Polylepis , at around 3900 m a.s.l. Under stones at the edge of a small stream. This biotope is 50 m away from that of D. placitus Moret sp. nov. Geographic distribution Microendemic species, restricted to the Guamaní area in the Eastern Cordillera.
