Differential diagnosis
Scipopus (Scipopus) cartaboensis resembles Scipopus (Scipopus) nitidus sp. nov. in having a shiny epicephalon and shiny, bare patches on the orbital plate, but differs in the blue vitta on the scutum, the orange clypeus and epicephalon, and the short female T1+2 (~1.6× length of T3).

Description
LENGTH. 11–15 mm.
HEAD. Palpus orange, pale brown microtrichose and setulose on entire surface, narrow (length 4.5× height). Clypeus orange or light brown, width ~2.0× height, bare medially, white microtrichose in posterolateral corners. Frontal vitta dull, orange, microtrichose. Orbital plate orange with anterior, shiny, orange or light brown bare patches (Fig. 11C). Epicephalon orange or light brown, shiny, silvery microtrichose, narrow (width less than ⅔ of frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. Paracephalon light brown or orange, slightly convex on outer portions. All head chaetotaxy well-developed.
THORAX. Scutum black-brown, black-brown microtrichose, with median blue sheen. Female cervical sclerite with slight anterior convex bump, otherwise relatively flat. Postpronotal lobe black-brown, pale microtrichose on ventral margin, setulose on outer margin. Notopleuron black-brown with pale microtrichosity outlining anterior notopleural seta and on ventral margin. Pleuron black-brown with the following microtrichosity: entirely white proepisternum and proepimeron, white on anteroventral ½ of anepisternum and posterodorsal corner, with ventral corner and remainder brown, almost entirely white on katepisternum, with median brown spot and dorsal patch (Fig. 11F), or white anteriorly and posteriorly (Fig. 11G), white on margins of katatergite. Legs black-brown; first fore and hind tarsomere dark brown with slight ventral golden fringe.
ABDOMEN (J+ ♀). Tergites black-brown. T1 with fine, long, white setae. Pleuron almost entirely dark brown or black, ventral ¼ of P2–6 pale grey (Fig. 11G).
FEMALE ABDOMEN. T1+2 ~1.6 × length of T3. Oviscape black-brown, white microtrichose on anterior ⅓, ~1.5–2.0 × length of T6. Combined spermathecal ducts short; common duct very short, almost absent. Paired spermathecal duct short (6.0–7.0 × length of paired spermathecae), narrow and curved basally, wider distally. Paired spermathecal stems same length as spermathecae, with rounded tubercles. Paired spermathecae narrower basally, wider apically, approximately teardrop-shaped. Single spermathecal duct arising from basal ¹/10 of paired duct, very narrow, less than ½ diameter and length of paired duct. Single spermatheca not clearly delineated, inornate, ending bluntly.
MALE ABDOMEN. T1+2 ~1.9× length of T3. Genital fork small, ~2.2× length of T6, with arms converging, nearly touching, inner basal process straight, ~½ length of arm. Epandrium of only available male broken, long setose posteroventrally. Basiphallus small, crescent-shaped. Basal distiphallus ~2.0 × length of phallic bulb. Phallic bulb short and small, length ≈ height, with upper chamber with posterior projection and lower chamber. Distal distiphallus broken off in only available male specimen, but apparently narrow. Phallapodeme not observed.
Remarks
A female of Scipopus (Scipopus) cartaboensis was photographed as it was ovipositing in rotting wood in Novo Airão, Brazil (Fig. 12A) and another individual was photographed in Presidente Figueriedo, Brazil, with an attached pseudoscorpion (Fig. 12B). The pseudoscorpion is not associated with the pinned specimen.
Distribution
Ecuador to Suriname (Steyskal 1968), French Guiana (new record).
