Paratetrapedia basilaris



( FIGS 63, 68, 93, 128, 163, 164 View Figures 159–170 )

Comments and diagnosis: Paratetrapedia basilaris can be recognized by the translucent hyaline margins of its terga. The male is easily distinguished from the other species of the bicolor group by its unmodified scape, not dilated apically. Additionally, as in P. vogeli , the male S6 has two rows of plumose setae on the lateral margins. Paratetrapedia basilaris differs from P. vogeli by the almost right angled omaulus.

Distribution: Brazil: Amapá, Amazonas, Pará; Guyana; French Guiana ( Fig. 68).


Holotype male: Body length: 7.0; maximum head width: 2.5; fore wing length (including tegula): 7.0. Colour. Integument mostly dark brown. Mandible with basal half pale yellow and apical half black; labrum pale yellow, almost white; clypeus with two yellow stripes on lateral margins, and a thin yellow stripe on lower margin; paraocular stripe very thin (c. 0.8 ¥ F2 diameter), occupying more than half of lower paraocular area; supraclypeal area with yellow spot on disc; frons with thin yellow stripe on mid line; genal area with thin and short yellow stripe on lower portion of ocular margin; scape pale brown, weakly yellow on outer lateral face; pedicel and antennal flagellomeres pale brown. Mesoscutum with two thin pale yellow stripes on disc and lateral margins; disc of scutellum with two yellow spots on lateral portions; axilla pale yellow dorsally. Terga and sterna pale brown; margins of sterna translucent hyaline, with silvery reflections. Wing membrane brown infumate; veins and pterostigma orange yellow; microtrichia dark brown. Tibial spurs white. Pubescence. Pubescence mostly white on paraocular area, mesepisternum and propodeum; remaining body with brownish pubescence. Scape with brown setae on inner face, c. 0.12 mm in length. Mesoscutum and scutellum with very short plumose pubescence, velvet-like. Terga with margins mostly glabrous; T4 mostly glabrous, with few plumose hairs on margin laterally; T5–T6 with margins glabrous; margin of S2 with row of continuous stout simple brown setae; margin of S3 with row of continuous stout simple pale yellow setae; S4 and S5 with pubescence typical of the genus; S6 with row of stout plumose setae on margins laterally, and short plumose hairs on the margin of apex. Integument sculpture. Clypeus and supraclypeal area with dense coarse punctures (<1 pd), intermingled amongst sparse minute punctures (> 3 pd); disc of frons with sparse coarse punctures (3 pd); antennal scrobe with dense fine punctures (1 pd), with one small smooth area. Mesoscutum and scutellum with fine dense punctures (0.5 pd), intermingled amongst coarse and sparser punctures (2 pd); metapostnotum with sparse fine punctures (2–3 pd); mesepisternum with sparse coarse punctures (3 pd), with smooth shiny integument between the punctures. Structure. Lamella of pronotal collar acute throughout its length. Disc of scutellum convex. Upper third of omaulus in acute angle, almost carinate. Head about 1.2¥ broader than long (2.5: 2.0); ratio of lower interocular distance to upper interocular distance: 0.76 (1.0: 1.3); clypeus c. 1.5¥ broader than long (1.0: 0.65); scape: length 0.8, maximum width 0.19; length of F1–3: 0.17, 0.12, 0.19; diameter of F2: 0.17.

Paratype female: Body length: 7.1; maximum head width: 2.6; fore wing length (including tegula): 7.2. Colour. Similar to male, except for yellow stripe on paraocular area slightly faint; genal area completely dark brown. Pubescence. Similar to male, except T4–T6 with marginal hair band of brown hairs throughout its margin. Integument sculpture. Similar to male, except that punctures denser and finer; clypeus and supraclypeal area with dense coarse punctures (<1 pd); disc of frons with dense coarse punctures (<0.5–2 pd), and dense fine on lateral portions (<1 pd). Structure. Similar to male; scutellum weakly convex, almost flat dorsally. Head about 1.2¥ broader than long (2.5: 2.0); ratio of lower interocular distance to upper interocular distance: 0.78 (1.1: 1.4); clypeus about 1.7¥ broader than long (1.1: 0.65); scape: length 0.7, maximum width 0.19; length of F1–F3: 0.16, 0.08, 0.10; diameter of F2: 0.16.

Variation: Two specimens from Manaus ( Brazil, Amazonas) have very faint yellow marks on paraocular area and frons. The colour of these specimens, however, has probably been altered by deterioration. Most examined female specimens have T4 with margins mostly glabrous, with few setae on lateral third, but other apparently better preserved specimens have a complete marginal band.

Etymology: The species name refers to the plesiomorphic characters of this species related to the other species of the bicolour group.
