Paratetrapedia chocoensis



( FIGS 57, 75 View Figure 75 , 109, 139 View Figures 138–146 , 201, 202)

Comments and diagnosis: Paratetrapedia chocoensis differs from P. atlantica , P. rufa , P. albilabris , P. andina , and P. albopilosa by the bicoloured integument (dark brown and yellow), by male T5 with band of dense plumose hairs extending throughout its entire margin, and yellow infumate wing membrane. Paratetrapedia chocoensis is very similar to P. flaveola , differing by having the lamella of pronotal collar with lateral portions diverging of margins of mesoscutum, yellow infumate wing membrane, completely orange yellow terga, yellow stripe on paraocular area weakly sinuous with upper portion obtuse, and smaller body size.


Holotype male: Body length: 6.5; maximum head width: 2.3; fore wing length (including tegula): 6.3. Colour. Integument mostly yellow. Mandible yellow with apex black; labrum, clypeus, and supraclypeal area yellow; yellow stripe on paraocular area on more than half of lower portion, and weakly sinuous and obtuse on upper portion; frons dark brown with thin short yellow stripe on mid line; genal area yellow; scape orange yellow; pedicel and flagellomeres reddish brown. Mesoscutum black with two thin yellow stripes on disc and lateral margins; scutellum and metanotum yellow; lateral area of metanotum yellow; axilla brown laterally; metapostnotum orange yellow, slightly dark; mesepisternum with anterior surface reddish brown and lateral surface yellow. Terga completely orange yellow. Wing membrane yellow infumate, with microtrichia yellow; fore wing membrane with apical third dark by brown microtrichia; veins and pterostigma orange yellow. Legs yellow; hind basitarsus brown; tibial spurs white. Pubescence. Mostly orange yellow, except hind basitarsus with dark brown pubescence. Scape with long pale yellow setae on inner face, about 0.2 mm in length; mesoscutum and scutellum with dense yellow short plumose pubescence; scutellum with long erect simple setae, about 0.16 mm in length; metapostnotum with short plumose hairs, about 0.1 mm in length. T4–T6 with marginal band of plumose yellow hairs throughout its margin; S2 with two short rows on mid portion of margin; S3 of male deeply concave in ‘U’ shape, covered by dense short plumose pubescence; S6 with two rows of stout plumose hairs on margins laterally, and short plumose hairs on margin of apex. Integument sculpture. Clypeus and supraclypeal area with coarse punctures (1–2 pd), intermingled amongst sparse minute punctures (> 2 pd); disc of frons with coarse punctures (2 pd), and minute punctures on lateral portions (1 pd). Mesoscutum and scutellum with fine dense punctures (<0.5 pd); metapostnotum with fine punctures, mostly sparse (1–2 pd); mesepisternum with dense coarse punctures laterally (0.5–1 pd). Structure. Lamella of pronotal collar with lateral portions weakly obtuse. Scutellum disc weakly convex, almost flat. Head about 1.2¥ broader than long (2.4: 1.8); ratio of lower interocular distance to upper interocular distance: 0.81 (1.1: 1.35); clypeus about 1.75¥ broader than long (1.05: 0.6); scape: length 0.6, width 0.2; length of F1–F3: 0.17, 0.12, 0.17; diameter of F2: 0.2.

Paratype female: Body length: 6.6; maximum head width: 2.5; fore wing length (including tegula): 7.0. Colour. Similar to male; wing membrane yellow infumate, darker than in female. Pubescence. Similar to male; scutellum with erect simple setae, about 0.2 mm in length; marginal bands on tergal margin, similar to male, except for T4–T6 with marginal hair band of simple orange yellow hairs occupying whole margin. Integument sculpture. Similar to male; clypeus with dense coarse punctures (<0.5 pd); supraclypeal area with dense coarse punctures intermingled amongst minute sparse punctures (> 2 pd); frons with sparse coarse punctures on disc and dense fine punctures on lateral portions (<0.5 pd); metapostnotum with dense minute punctures (1 pd) on lateral portions, with coarser punctures on disc. Structure. Lamella of pronotal collar with lateral portions obtuse. Disc of scutellum almost flat, and profile slightly truncated. Head about 1.2¥ broader than long (2.5: 2.0); ratio of lower to upper interocular distance: 0.81 (1.2: 1.4); clypeus about two times broader than long (1.1: 0.55); scape: length, 0.7, maximum width, 0.2; length of F1–F3: 0.22, 0.2, 0.17; diameter of F2: 0.2.

Variation: Most male specimens have marginal hair band on T4 incomplete, occupying less than one-third of margin laterally, but a few specimens have one isolated band on the mid portion of margin. Males and females can have the colour of mesepisternum, propodeum, and metapostnotum completely yellow or reddish brown. Three specimens from Ecuador have wing membrane pale brown infumate, leg pubescence completely yellow, metapostnotum and ventral portion of mesepisternum reddish brown. The specimen from Colombia, collected in the Chocó region, has the same colour pattern as the holotype, except for the hind basitarsus with mostly yellow pubescence and a few sparse long dark brown setae .

Etymology: The species name refers to the Choco region.

Distribution: Colombia; Costa Rica; Ecuador; Panama ( Fig. 75 View Figure 75 ).
