Differential diagnosis

Scipopus (Parascipopus) fenestratus resembles S. (Pa.) nigriscapus sp. nov. in having a mostly orange body, but it differs by the three well-defined subapical hyaline spots on the wing, the absence of an apical scutellar seta, and the black distal and basal bands on the femora.

Etymology

The species name, from the Latin noun for ‘window’, refers to the subapical well-defined, window-like hyaline spots on the wing.

Description

LENGTH. 13–15 mm.

HEAD. Antenna orange. Palpus orange, pale orange microtrichose and sparsely black setulose on entire surface, broad (length 3.1× height). Clypeus orange, width ~2.4× height, silvery microtrichose on entire surface. Frontal vitta entirely dull, orange, microtrichose, tapered posteriorly but posterior apex expanded. Orbital plate dull, orange, microtrichose, clearly delineated. Epicephalon orange, shiny, white-microtrichose, wide (width>⅔ of frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. Paracephalon orange or light brown. One lower fronto-orbital seta, upper fronto-orbital seta absent or present, outer vertical seta absent, all other head chaetotaxy well-developed.

THORAX. Scutum orange, microtrichose. Female cervical sclerite convex. Postpronotal lobe orange, orange setulose anteriorly and on outer margin. Notopleuron orange. Pleuron orange, uniformly white microtrichose. Tibiae dark brown or black, fore femur orange on basal ¾, dark brown or black apically, mid and hind femora pale brown or orange basally and preapically, darker brown or black medially, black apically. First fore tarsomere yellow, hind tarsomere 1 dark brown or black with ventral golden fringe. Wing brown infuscate on r 1, distal ½ and apex; with three hyaline window-like spots in m 1, r 2+3, r

3+4 ( Fig. 37A ).

ABDOMEN (J+ ♀). Tergites orange or brown, black setulose. T1 with long, fine, yellow or orange setae. Pleuron yellow or pale orange, microtrichose, dark orange or brown on P1, dorsal half of P2–6 dark orange ( Fig. 37B ).

FEMALE ABDOMEN. T1+2 ~2.2× length of T3. Oviscape orange and/or brown, white microtrichose on anterior ½, ~4.0–5.0 × length of T6. Combined spermathecal duct length short; common duct ½ of entire duct length. Paired spermathecal duct very short (1.0–2.0 × length of paired spermathecae), very swollen medially, less swollen apically. Paired spermathecal stems inornate, bulbous and wrinkled, longer than spermathecae. Paired spermathecae spherical, with apical indentation (collapsed in Fig. 36A ). Single spermathecal duct arising from base of paired duct, narrow, ½ the diameter and ≈ length to paired duct. Single spermatheca swollen distally, inornate.

MALE ABDOMEN. T1+2 ~3.0× length of T3. T6 short, genital fork 2.3 × as long as T6, arms converging, inner basal process angled inwards, ¹/5 the length of arm. Epandrium elongate, length ~2.0× height, short setose on posteroventral margin. Basiphallus small, crescent-shaped. Basal distiphallus long (~½ epandrial length), ending in small, short (length ≈ height) single-chambered phallic bulb, with narrow anterior projections. Distal distiphallus narrow, long (≈ length to epandrium), with apex slightly expanded and tube-like. Phallapodeme broad and expanded apically. Hypandrium expanded anteriorly.

Distribution

Costa Rica.
