Differential diagnosis

Scipopus (Parascipopus) monteverde sp. nov. resembles S. (Pa.) tico sp. nov. in having an orange frontal vitta and a primarily dark brown or black body with a blue sheen, but it differs in having evenly dark brown or black femora, a darkly infuscate wing, and a dark brown or black first fore tarsomere.

Etymology

The name is a noun in apposition inspired by the type locality.

Description

LENGTH. 10–13 mm.

HEAD. Antenna orange. Palpus dark brown, apically light brown and pointed, pale microtrichose and setulose, narrow (length 4.1 × height). Clypeus dark brown or black, width ~2.1× height, silvery microtrichose on entire surface. Frontal vitta dull, orange, microtrichose, posterior apex strongly tapered to a point ( Fig. 41D ). Orbital plate orange, shiny, bare, clearly delineated. Epicephalon black or dark brown, shiny, bare, wide (width>⅔ of upper frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. Paracephalon dark brown or black. Upper fronto-orbital seta and one of the usual two lower fronto-orbital setae absent, all other head chaetotaxy well-developed.

THORAX. Scutum black, brown microtrichose, with a wide, shiny, blue indistinct sheen medially. Female cervical sclerite slightly convex. Postpronotal lobe black, setulose anteriorly. Notopleuron black with blue sheen at some angles. Pleuron black with blue sheen, entirely covered in silvery microtrichosity, denser on posterior katepisternum, forming silvery transverse band only seen at some angles ( Fig. 41F ). Legs black, mid and hind femora sometimes slightly paler basally; fore and hind first tarsomere black with ventral golden fringe. Wing slightly brown infuscate. Apical scutellar seta absent.

ABDOMEN (J+ ♀). T1 with fine, long, white setae.

FEMALE ABDOMEN. Pleuron mostly dark brown or black, ventral half of P1–3 grey ( Fig. 41G ). T1+2 ~2.2 × length of T3. Oviscape black, setulose, white microtrichose on anteroventral and lateral ⅓, dorsomedian ¹/6; ~3.0× length of T6. Common duct very short, ⅛ of entire duct length. Paired spermathecal duct long (7.0 × length of paired spermathecae), mostly parallel-sided, wider basally, swollen apically. Paired spermathecal stems separated into very short, narrow basal section and long, swollen, distal section; sparse tubercles at base of paired spermathecae. Paired spermathecae cup-like, with apical indentation. Single spermathecal duct arising from basal ¹/6 of common duct, narrow, ½ diameter of base of paired duct, <½ the length of paired duct, slightly swollen apically. Single spermatheca teardrop-shaped, elongate.

MALE ABDOMEN. Pleuron pale grey or off-white, dark brown or black on P1, dorsal ¾ of pleural sac and dorsal half of P2–6. T1+2 ~2.6× length of T3. Genital fork 2.0× as long as T6, arms converging; inner basal process angled inwards, ¹/6 the length of arm. Epandrium elongate (length ~2.0× height), long setose on posteroventral margin. Basiphallus small, projecting posteriorly, crescent-shaped. Basal distiphallus long (> ½ epandrial length), partially ending in large, long (length 2.0× height), approximately ovoid phallic bulb. Distal distiphallus wide, long (≈ length to epandrium, diameter slightly greater than basal distiphallus). Phallapodeme apically expanded and broad (not visible in Fig. 41E ). Anterior hypandrium expanded.

Remarks

A female S. (Pa.) monteverde sp. nov. was photographed ovipositing in mossy substrate in Monteverde, Costa Rica ( Fig. 41G ).

Distribution

Costa Rica.
