Differential diagnosis

Scipopus (Scipopus) calocephalus resembles S. (S.) cartaboensis in having a dark first fore tarsomere, a shiny epicephalon that is clearly delineated from the upper frontal vitta, and similar median vitta on the scutum, but differs in the entirely dull, microtrichose orbital plate.

Description

LENGTH. 12–17 mm.

HEAD. Palpus dark brown, pale brown microtrichose and setulose on entire surface, denser on ventral edge, narrow (length 5.7× height). Clypeus light brown to black-brown, width ~2.0 × height, white microtrichose in posterolateral corners. Frontal vitta and orbital plate dull orange, microtrichose. Epicephalon orange or dark brown, shiny, bare anteriorly, white microtrichose posteriorly, narrow (width less than ⅔ of upper frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. Paracephalon light to dark brown, slightly convex on posterolateral portions. All head chaetotaxy well-developed.

THORAX. Scutum black-brown, microtrichose, with anteromedian pale brown vitta flanked by blue sheen. Female cervical sclerite convex. Postpronotal lobe black-brown, some setulae on anterior outer margin. Notopleuron black-brown with pale ventral line of microtrichosity. Pleuron black-brown with the following microtrichosity: entirely white on proepisternum, white with brown median stripe on proepimeron, anteroventral ½ and small posterior spot white on anepisternum, with ventral corner and remainder brown, mostly white on katepisternum with brown posterodorsal margin and ventral brown stripe ( Fig. 10G ) or completely white ventrally on katepisternum ( Fig. 10F ), white anteriorly on katatergite. Legs black, fore and hind first tarsomere dark brown with ventral golden fringe. Wing uniformly brown infuscate.

ABDOMEN (J+ ♀). T1 with fine, long, white setae. Pleuron pale grey to light brown, P1, dorsal half of P2–6 dark brown.

FEMALE ABDOMEN. T1+2 approximately twice the length of T3. Oviscape dark brown basally, black apically, sparse black setulose, white-microtrichose on anterior ⅓, ~2.0–3.0× length of T6. Combined spermathecal ducts long and narrow; common duct ¹/5 –⅓ of entire duct length. Paired spermathecal duct short (~6.0–8.0× length of paired spermathecae), narrow, parallel-sided, swollen apically. Paired spermathecal stems of same length or longer than spermathecae with sparse, spiked tubercles. Paired spermathecae approximately spherical or ovoid, striate. Single spermathecal duct arising from basal ¹/10 of paired duct, narrow, ½ the diameter and length of paired duct, swollen apically. Single spermatheca elongate, with sparse, spiked tubercles.

MALE ABDOMEN. T1+2>2× length of T3. Genital fork with arms converging, nearly touching, inner basal process slightly curved outwards, ~½ the length of arms. Epandrium length 2.0× height, rounded posteriorly, densely short setose on posteroventral margin. Basiphallus small, crescent-shaped. Basal distiphallus short (~2.0 × phallic bulb). Phallic bulb short, length ≈ height, approximately round, with upper chamber with small, round, posterior projection and lower chamber. Distal distiphallus long and slender (1.5–2.0× length of epandrium). Phallapodeme apically expanded and broad.

Remarks

Bigot (1886) described Scipopus calocephalus as having a white first fore tarsomere, which is an error as the type specimens very clearly have a dark brown first fore tarsomere. The type of Scipopus frit is apparently identical to that of S. (S.) calocephalus .

Distribution

Mexico to Panama, Venezuela and Colombia ( Steyskal 1968).
