Differential diagnosis

Scipopus (Scipopus) souzalopesi closely resembles S. (S.) erythrocephalus in having a dull, orange epicephalon, shiny, bare anterior patches on the orbital plate and a dark first fore tarsomere. Scipopus (S.) souzalopesi differs in the distinct pattern of pale microtrichose spots on the scutum, the long (3.0– 4.0× as long as T6) oviscape, and the small (~2.3 × length of T6) genital fork.

Description

LENGTH. 9–15 mm.

HEAD. Palpus orange, pale brown microtrichose, black setulose, narrow (length 4.3 × height). Clypeus orange or light brown, width ~2.0× height, bare medially, white microtrichose in posterolateral corners. Frontal vitta dull, orange, microtrichose, orbital plate anteriorly bare, shiny, orange or light brown. Epicephalon dull, orange, microtrichose, not clearly delineated from upper frontal vitta. Paracephalon orange or light brown, slightly convex on posterolateral portions. All head chaetotaxy well-developed (missing in specimen from Fig. 31 ).

THORAX. Scutum black-brown, dark brown microtrichose with indistinct pale brown median vitta flanked by blue sheen; distinct pale brown microtrichosity above anterior postpronotal lobe, indistinct pale spots anterior and posterior to transverse suture, pair of small pale brown spots on most median points of transverse suture ( Fig. 31C ). Female cervical sclerite relatively flat. Postpronotal lobe dark brown, several short setulae on outer margin. Notopleuron dark brown with pale microtrichose spots. Thorax dark brown or black with the following microtrichosity: entirely white on proepisternum and proepimeron, white on anteroventral ½ and posteromedian margin of anepisternum ( Fig. 31E ), otherwise brown, mostly white on katepisternum, with brown spots ventrally, posterodosally and medially, white with brown median spot on katatergite. Legs black-brown with blue sheen. First fore and hind tarsomere brown with ventral golden fringe. Wing uniformly brown infuscate.

FEMALE ABDOMEN. T1 with fine, long, white setae. T1+2 ~2.0 × length of T3. Pleuron grey microtrichose, P1, dorsal half of P2–3 and P6, entirety of P4–5 dark brown. Oviscape black, sparsely setulose, pale brown microtrichose on ventral ⅓, ~3.0–4.0× length of T6. Combined spermathecal ducts short and narrow; common duct just under ½ of entire duct length. Paired spermathecal duct narrow, short (≈ to spermathecal length, although spermathecae are longer in this species), parallel-sided, apex very swollen. Paired spermathecal stems very short, almost absent. Paired spermathecae narrow, elongate, curved apically with numerous reflexed tubercles. Single spermathecal duct arising from basal ⅛ of paired duct, narrow, ½ diameter and ⅔ length of paired duct, swollen apically. Single spermatheca finger-like and elongate, with sparse tubercles.

MALE ABDOMEN (from Albuquerque 1972b). T1+2 approximately twice the length of T3. Genital fork ~2.3× length of T6, arms converging, inner basal process straight, ¹/5 the length of arm. Epandrium elongate (length>2.0× height), rounded posteriorly, sparsely short setose on posteroventral margin. Basiphallus small, crescent-shaped. Basal distiphallus short (~3.0× phallic bulb length), broad, ending in short (length ≈ height), small phallic bulb with upper and lower chamber. Distal distiphallus long, expanded apically, ~2.0 × length of epandrium. Phallapodeme slender, not apically expanded.

Distribution

Brazil, Colombia (new record), Ecuador (new record), Peru (new record).
