PARATETRAPEDIA ATLANTICA SP. NOV.

( FIGS 76 , 110, 145 , 195, 196)

Comments and diagnosis: Paratetrapedia atlantica is very similar to the species with dark brown integument of the flavipennis group. It differs from these species by pubescence on posterolateral margin of scutellum composed of dark brown plumose hairs and mesoscutum completely black with faint yellow stripes on disc. The female is also distinct by T1 with minute punctures (mainly on vertical surface), and transition zone between metapostnotum and propodeum with minute punctures. The male of P. atlantica is distinct from P. albopilosa by T5 with completely glabrous margin.

Description

Holotype male: Body length: 8.1; maximum head width: 2.6; fore wing length (including tegula): 8.1. Colour. Integument mostly dark brown; mandible yellow with apex black; labrum black, weakly yellow; clypeus with two weak faint yellow spots on lateral margins; lower paraocular area with thin faint yellow stripe, occupying more than lower half of paraocular area; scape, pedicel, and flagellomeres reddish brown. Central portion of metanotum weakly orange yellow. Wing membrane brown infumate with dark microtrichia dispersed; veins and pterostigma orange yellow. Tibial spurs white. Pubescence. Mostly dark brown, except paraocular areas, mesepisternum, and propodeum with white pubescence. Mesoscutum and scutellum with dense plumose pale brown pubescence; posterolateral margin of scutellum with long plumose dark brown hairs; metapostnotum with plumose hairs, about 0.12 mm in length; T4 with few brown plumose hairs on less than one third of margin laterally; T5–T6 with margin glabrous; S2 with two short rows of simple erect setae on mid portion of margin; S3 of male with deeply concave area in ‘U’ shape covered by dense short plumose pubescence; S6 with two rows of plumose hairs on margin laterally and short plumose hairs on margin of apex. Integument sculpture. Clypeus and supraclypeal area with shallow coarse punctures (0.5–2 pd), intermingled amongst sparse minute punctures (> 2 pd); frons with coarse punctures, mostly sparse (2 pd), intermingled amongst minute punctures on upper portion; antennal scrobe with dense minute punctures (<0.5 pd). Mesoscutum and scutellum with minute punctures (<0.5 pd), intermingled amongst sparse coarse punctures (2 pd); metapostnotum with dense minute punctures on lateral portions (<0.5 pd), and coarser punctures on disc (0.5 pd); mesepisternum with coarse sparse punctures (> 3 pd), with few dense punctures on omaular area (0.5–1 pd). Structure. Lamella of pronotal collar obtuse laterally and weakly divergent. Scutellum disc strongly convex. Head about 1.2¥ broader than long (2.65: 2.1); ratio of lower to upper interocular distance: 0.78 (1.1: 1.4); clypeus about 1.7¥ broader than long (1.1: 0.65); scape: length 0.65, maximum width 0.17; length of F1–F3: 0.2, 0.15, 0.18; diameter of F2: 0.18.

Paratype female: Body length: 8.0; maximum head width: 2.65; fore wing length (including tegula): 8.0. Colour. Similar to male, except for paraocular area and frons without yellow marks. Pubescence. Similar to male, except for T5–T6 with marginal band throughout margin. Integument sculpture. Similar to male except for clypeus and supraclypeal area with dense coarse punctures (0.5–1 pd); disc of frons with dense coarse punctures (<0.5–2 pd); coarse punctures on disc of frons almost with same diameter; lateral portions of frons and antennal scrobe with dense fine punctures (<0.5 pd). Structure. Lamella of pronotal collar with lateral portions conspicuously obtuse. Scutellum disc weakly convex. Head about 1.2¥ broader than long (2.65: 2.15); ratio of lower interocular distance to upper interocular distance: 0.86 (1.25: 1.45); clypeus about 1.8¥ broader than long (1.1: 0.6); scape: length 0.75, maximum width 0.2; length of F1–F3: 0.22, 0.12, 0.17; diameter of F2: 0.25.

Variation: Most specimens have the only a very faint yellow stripe on paraocular area, clypeus completely brown with narrow yellow stripes on margins laterally, and genal area completely brown. Colour of terga of P. atlantica can vary between pale brown to dark brown, almost black. One male specimen has a completely smooth frons.

Etymology: The species name refers to the Atlantic Forest.

Distribution: Brazil: Espírito Santo, Rio de Janeiro, São Paulo ( Fig. 76 ).
