Differential diagnosis

Scipopus (Phaeopterina) quetzal sp. nov. resembles the sympatric species S. (Ph.) guatemalensis and S. (Ph.) uniformis sp. nov. in having a brown median stripe on the clypeus, but it differs by the white microtrichose clypeus, the bright orange subapical band on the mid femur and the strongly convex female cervical sclerite.

Etymology

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

Type material examined

Holotype

GUATEMALA • 1 ♀; Baja Vera , Biotopo Quetzal; 15°12′49″ N, 15°12′49″ W; 1690 m a.s.l.; 7–10 May 2009; cloud forest; Malaise trap; debu00334712/MYCRO607-19 sequenced for CO1–5′, CO1–3′, 12S, 28S; UVG (dissected and photographed, Fig. 65A–D ).

Description

LENGTH. 12 mm.

HEAD. Palpus orange, pale microtrichose and setulose, narrow (length 5.0 × height). Clypeus orange, brown medially, width ~1.6 × height, silvery microtrichose on entire surface. Frontal vitta dull, orange, microtrichose. Epicephalon light brown and/or orange, shiny, wide (width ⅔ or more of upper frontal vittal width at inner verticals), clearly delineated from upper frontal vitta. Paracephalon light brown and/ or orange. One lower fronto-orbital seta absent; all other head chaetotaxy well-developed.

THORAX. Scutum black-brown, dark brown microtrichose with a wide, shiny, silvery-blue median sheen. Female cervical sclerite strongly convex. Postpronotal lobe black-brown, sparsely setulose on outer lateral margin. Notopleuron black-brown. Thorax dark black-brown with blue sheen, entirely silvery microtrichose. Legs dark brown, mid femur with subapical bright orange band; fore tarsomere 1 entirely white, mid tarsomere 1 brown, hind leg and tarsomeres unknown. Wing entirely brown infuscate.

FEMALE ABDOMEN. T1 with fine, long, dark brown or black setae. Pleuron pale grey, faded on available specimen but apparently darker grey or brown on P1, P2 and dorsal half of P3–6. Posterior margin of T2 ~1.5× as wide as T1 dorsally. T1+2 ~2.0 × length of T3. Oviscape black-brown, microtrichosity not observed (dissected), ~3.0 × length of T6. Common duct very short, smooth, not delineated form paired duct. Paired duct short (4.0 × length of paired spermathecae), narrow, relatively parallel-sided. Paired spermathecal stems not differentiated from spermathecae. Paired spermathecae elongate, ringed by well-defined striae and ridges. Single spermathecal duct arising from base of paired duct, narrow, ½ the diameter and ¾ the length of paired duct, with small swollen bulb apically. Single spermatheca similar to paired but much smaller.

MALE ABDOMEN. Not observed.

Distribution

Guatemala.
