PARATETRAPEDIA ALBOPILOSA SP. NOV.

( FIGS 76 , 112, 143 , 203, 204)

Comments and diagnosis: Paratetrapedia albopilosa is very similar to P. atlantica and P. albilabris . It differs from both P. atlantica and P. albilabris by frons weakly convex and area of transition between metapostnotum and scutellum smooth, and from P. atlantica by white plumose pubescence on posterolateral portions of scutellum (as in P. albilabris , Fig. 65). The male is distinct by large yellow marks on frons, labrum completely yellow, paraocular area with large yellow stripe and genal area with thin yellow stripe on lower third. The male of P. albopilosa also differs from P. albilabris by hind basitarsus without an acute tooth on anterior margin.

Description

Holotype male: Body length: 6.8; maximum head width: 2.5; fore wing length (including tegula): 7.3. Colour. Integument mostly dark brown; terga and sterna pale brown, almost yellow; mandible yellow with apex black; labrum pale yellow; clypeus with two pale yellow spots on lateral margins; supraclypeal area weakly pale yellow; paraocular area with yellow stripe; disc of frons with thin yellow stripe on mid

·

line, weak; genal area with small yellow stripe on lower third; scape, pedicel, and flagellomeres reddish brown. Mesoscutum with two thin yellow stripes very faint on disc. Fore wing membrane brown infumate because of dark brown microtrichia; veins and pterostigma yellow. Tibial spurs white. Pubescence. Genal area, mesepisternum, propodeum, and sterna with pubescence mostly white; remaining body with pubescence brown. Mesoscutum and scutellum with dense plumose pale brown pubescence; posterolateral portions of scutellum with dense pale brown pubescence; metapostnotum with short plumose hairs, about 0.08 mm in length. T4–T6 with margins mostly glabrous; S2 with two short rows of simple erect setae on mid portion; S3 deeply concave in ‘U’ shape, covered by dense short plumose pubescence; S4 and S5 typical of the genus; S6 with two rows of stout plumose hairs on margins laterally, and short plumose hairs on margin of apex. Integument sculpture. Clypeus with shallow coarse punctures (0.5–2 pd), intermingled amongst sparse minute punctures (2 pd); supraclypeal area with dense coarse punctures on lateral portions (<1 pd), and sparse coarse punctures on disc (> 2 pd); frons with heterogeneous punctures: coarse punctures mostly sparse (2 pd), intermingled amongst sparse minute on upper portion of disc; integument amongst punctures smooth and shiny; antennal scrobe with dense minute punctures (<0.5 pd). Mesoscutum and scutellum with dense minute punctures (<1 pd), intermingled amongst sparse coarser punctures (2 pd); metapostnotum with dense fine punctures on disc (0.5 pd) and dense minute punctures on lateral margins (<0.5 pd); transition area between metapostnotum and propodeum with smooth and shiny area; mesepisternum with coarse punctures, mostly sparse (> 3 pd), with some denser punctures on omaular area (0.5–1 pd). Structure. Lamella of pronotal collar with lateral portions obtuse. Scutellum conspicuously convex. Head about 1.2¥ broader than long (2.5: 2.1); ratio of lower to upper interocular distance: 0.8 (1.05: 1.3); clypeus about 1.5¥ broader than long (1.0: 0.65); scape: length 0.82, maximum width 0.8; length of F1–F3: 1.8, 0.14, 0.2; diameter of F2: 0.16.

Paratype female: Body length: 8.2; maximum head width: 2.7; fore wing length (including tegula): 7.6. Colour. Similar to male, except yellow marks on frons faint; pedicel and flagellomeres weakly orange yellow; metasoma pale yellow ventrally. Pubescence. Similar to male, except for T5–T6 with marginal band of simple setae occupying whole margins. Integument sculpture. Similar to male, but denser; clypeus with dense coarse punctures (0.5 pd), intermingled amongst sparse minute punctures (> 2 pd); supraclypeal area with dense coarse punctures (0.5 pd); disc of frons with dense coarse punctures intermingled amongst fine punctures (<0.5 pd); antennal scrobe with dense minute punctures (<0.5 pd), with small smooth area above the antennal socket. Metapostnotum with dense minute punctures on lateral portions (1 pd), and coarser punctures on disc (1–2 pd); transition zone between metapostnotum and propodeum with small smooth and shiny area; mesepisternum with sparse coarse punctures (2 pd), and some dense punctures on omaular area (0.5 pd). Structure. Similar to male; lamella of pronotal collar with lateral portions obtuse; scutellum disc convex, almost flat. Head about 1.2¥ broader than long (2.7: 2.2); ratio of lower to upper interocular distance: 0.85 (0.12: 0.14); clypeus about 2.1¥ broader than long (1.2: 0.5); scape: length 0.75, maximum width 0.2; length of F1–F3: 0.18, 0.12, 0.2; diameter of F2: 0.2.

Variation: Most males have T5 with margins completely glabrous, but a few specimens have short marginal band occupying less than one third of the margin laterally. The colour of sterna and terga can vary from pale brown, almost yellow, to dark brown.

Etymology: The species name refers to white pubescence on posterolateral portion of scutellum.
