Differential diagnosis

Scipopus (Phaeopterina) noturgidus sp. nov. resembles S. (Ph.) turgidus sp. nov., S. (Ph.) argentum sp. nov. and S. (Ph.) zeta in having a brown first fore tarsomere and brown infuscate wing, but differs by the short anterior face of the clypeus (width 2.0× height), the brown first hind tarsomere, the black-brown scutum and the absent postocellar seta. The female terminalia of S. (Ph.) noturgidus are nearly identical to those of S. (Ph.) heteropus , but S. (Ph.) noturgidus differs externally by the orange epicephalon and paracephalon, and the relatively uniform dark brown or black legs.

Etymology

This species was named by adding a prefix to the superficially similar S. (Phaeopterina) turgidus sp. nov.

Paratype

COLOMBIA • 1 ♀; same collection data as for holotype; debu01089021/MYCRO604-19 sequenced for CO1–5′; IAVH (dissected and photographed, Fig. 64C ) .

Description

LENGTH. 15 mm.

HEAD. Palpus orange, pale microtrichose and black setulose, narrow (length 4.5 × height), apex pointed. Clypeus orange, width ~2.5× height, silvery microtrichose on entire surface. Frontal vitta dull, orange, microtrichose. Epicephalon orange and/or light brown, shiny, bare, wide (width ⅔ or more of upper frontal vittal width at inner verticals), clearly delineated from upper frontal vitta. Anterior lower fronto-orbital seta and postocellar seta absent, all other head chaetotaxy well-developed.

THORAX. Scutum black-brown with a wide, silvery blue median sheen. Female cervical sclerite relatively flat. Postpronotal lobe black-brown, some setulae on outer lateral margin. Notopleuron black-brown with indistinct pale microtrichosity surrounding anterior notopleural seta and on ventral margin. Thorax black-brown with blue sheen, entirely silvery microtrichose. Legs dark brown, mid and hind femur light brown basally, gradually fading to dark brown apically. Fore and hind tarsomere 1 dark brown with ventral golden fringe. Wing entirely brown infuscate.

FEMALE ABDOMEN. T1 with fine, long, white setae. Pleuron pale grey, dorsal half of P2 dark brown, dorsal half of P3–5 dark grey ( Fig. 64C ). T1+2 ~2.0× length of T3; posterior margin of T2 ~1.3× as wide as T1. Oviscape dark brown, black setulose, white microtrichose on anterior ⅓, ~2.5× length of T6. Spermathecal complex with two paired ducts arising separately from bursa copulatrix, each duct narrow, parallel-sided with apical bulb-like swelling. Paired spermathecal stems elongate, slightly sinuate, longer than spermathecae. Paired spermathecae elongate, nearly almond-shaped; one pair with flat, invaginated apices, the other pair with pointed projections arising from apical invaginations. Both spermathecal ducts and all four spermathecae similar in size and shape.

MALE ABDOMEN. Not observed.

Distribution

Colombia.
