Differential diagnosis

Scipopus (Parascipopus) otisi sp. nov. resembles S. (Pa.) savegre sp. nov. and S. (Pa.) manifestus in having a mostly black or dark brown body, but differs in having a highly contrasting, basally yellow femur.

Etymology

The name is a patronym honoring Gard Otis, a fellow field entomologist, long-time colleague of the second author, and professor, mentor, and colleague to the first author at the University of Guelph.

Description

LENGTH. 11–13 mm.

HEAD. Antenna black. Palpus dark brown, pale brown microtrichose and setulose on entire surface, denser on ventral edge and apex, narrow (length 4.5× height). Clypeus dark brown or black, width ~2.0× height, silvery microtrichose on entire surface. Frontal vitta dark brown or black, microtrichose, posterior apex tapered to a sharp point. ( Fig. 43D ). Orbital plate dark brown or black, shiny, bare, clearly delineated ( Fig. 43A ). Epicephalon dark brown or black, shiny, bare, wide (width>⅔ of frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. Paracephalon dark brown or black. All head chaetotaxy normally well-developed but one or both outer vertical setae absent in two specimens.

THORAX. Scutum dark brown or black with a silvery blue sheen medially, brown microtrichose. Female cervical sclerite convex. Postpronotal lobe dark brown or black, setulose on outer lateral margin. Notopleuron dark brown or black. Pleuron dark brown or black, entirely silvery microtrichose; microtrichosity denser anteriorly and posteriorly, forming posterior transverse band only seen at some angles. Legs mostly dark brown or black, fore femur yellow on basal ¼, mid and hind femora yellow on basal ½ to ¾. Fore tarsomere 1 almost entirely white, hind tarsomere 1 dark brown or black with ventral golden fringe. Wing mostly hyaline, very slightly brown infuscate on apex. Apical scutellar seta absent.

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

FEMALE ABDOMEN. Pleuron pale grey, microtrichose, dark grey or black on dorsal half of P1–6 (not evident in Fig. 43F as specimen is discoloured). T1+2 ~2.4 × length of T3. Oviscape dark brown or black, white microtrichose on anterior ⅓, ~4.0 × length of T6. Combined spermathecal duct length short; common duct ½ of entire duct length. Paired spermathecal duct short (4.0 × length of paired spermathecae), narrow and curved basally, wider medially and distally. Paired spermathecal stems slightly sinuate and curved, slightly bulbous, longer than spermathecae. Paired spermathecae ovoid, with apical indentation. Single spermathecal duct arising from base of common duct,> ½ diameter and length of paired duct, slightly swollen apically. One or two elongate, distally wider “single” spermathecae.

MALE ABDOMEN. Pleuron pale grey, microtrichose, P1, 3–6 light grey, pleural sac dark grey or black. T1+2 ~2.7 × length of T3. T6 short, genital fork dark brown, 2.0× as long as T6, arms converging, inner basal process slightly converging, ½ the length of arm. Epandrium elongate, length ~2.0 × height, short setose on posteroventral margin. Basiphallus small, frame-like. Basal distiphallus short (> ½ epandrial length), ending in small, approximately round, short, phallic bulb with rounded posterior projection and rounded lower chamber. Distal distiphallus narrow, long (≈ in length to epandrium), apex very slightly expanded. Phallapodeme very broad and expanded apically. Anterior hypandrium expanded and broad.

Remarks

Species of Scipopus s. lat. normally lack presutural dorsocentral seta, but one specimen of S. (Pa.) otisi sp. nov. has two pairs of short presutural dorsocentral setae. One specimen has only a single outer vertical seta, and another is missing both outer verticals.

Distribution

Costa Rica.
