PARATETRAPEDIA RUFA SP. NOV.
Comments and diagnosis: Paratetrapedia rufa is very similar structurally to P. atlantica , differing mainly by its orange yellow integument and mostly smooth female T1. Females of P. rufa can be confused with those of P. testacea because of their orange yellow integument, but the former has an obtuse lamella on the pronotal collar and metapostnotum mostly with densely fine punctures (1 pd).
Holotype male: Body length: 8.7; maximum head width: 2.5; fore wing length (including tegula): 8.5. Colour. Integument mostly orange yellow; face with yellow marks weakly conspicuous ( Fig. 50). Mesoscutum with two thin yellow stripes on disc and lateral margins; disc of mesoscutum dark brown and lateral portions orange yellow ( Fig. 62); axilla dark brown laterally. Wing membrane orange yellow infumate, with brown microtrichia; veins and pterostigma orange yellow. Tibial spurs pale yellow. Pubescence. Mostly orange yellow. Legs with orange yellow pubescence. Scape with brown short setae on inner face, about 0.2 mm in length. Mesoscutum and scutellum with pale yellow plumose hairs; scutellum with long erect simple setae, about 0.2 mm in length; metapostnotum with dense short plumose hairs, about 0.14 mm in length. Margins of T4–T6 completely glabrous, with few setae on margin laterally; S2 with two small rows of simple setae on posterior margin; S3 of male with deeply concave area in ‘U’ shape covered by dense short plumose pubescence; S4 and S5 typical of genus; S6 with two rows of stout plumose hairs on margin laterally, and short plumose hairs on margin of apex. Integument sculpture. Clypeus with dense coarse punctures (1 pd) intermingled amongst dense minute punctures (1 pd); supraclypeal area with dense coarse punctures (<0.5 pd) intermingled amongst minute punctures (1–2 pd); disc of frons with dense coarse punctures (<0.5 pd), and dense fine punctures on lateral portions and antennal scrobe (<0.5 pd). Mesoscutum and scutellum with dense fine punctures (<0.5 pd); metapostnotum with dense fine punctures (1 pd), and minute punctures on lateral margins (1 pd); mesepisternum with dense coarse punctures, mostly sparse (2 pd). Structure. Lamella of pronotal collar with lateral portions obtuse. Scutellum disc convex, weakly concave on mid line. Head about 1.2¥ broader than long (2.5: 2.1); ratio of lower to upper interocular distance: 0.82 (1.15: 1.4); clypeus about 1.7¥ broader than long (0.57: 0.32); scape: length 0.65, maximum width 0.22; length of F1–F3: 0.17, 0.15, 0.2; diameter of F2: 0.2.
Paratype female: Body length: 7.4; maximum head width: 2.6; fore wing length (including tegula): 7.4. Colour. Similar to male, except for disc of mesoscutum pale orange. Pubescence. Similar to male, except for inner surface of scape with short simple yellow setae, about 0.04 mm in length; mesoscutum and scutellum with short pale yellow plumose pubescence; scutellum with long erect simple setae, about 0.2 mm in length; metapostnotum with dense short plumose pubescence, about 0.08 mm in length. T5–T6 with marginal hair band distributed throughout its margin. Integument sculpture. Similar to male, except for clypeus with dense coarse punctures (0.5–1 pd); supraclypeal area with dense coarse punctures (<0.5 pd); disc of frons with dense coarse punctures (<0.5 pd); lateral portions of frons and antennal scrobe with dense fine punctures (0.5 pd); mesoscutum and scutellum with dense fine punctures (0.5 pd) intermingled amongst coarser and sparser punctures (1–4 pd); metapostnotum mostly with dense minute punctures (0.5–1 pd), with some coarser punctures on disc; mesepisternum mostly with sparse coarse punctures (1–3 pd). Structure. Lamella of pronotal collar with lateral portions obtuse. Scutellum disc weakly convex, almost flat. Head about 1.2¥ broader than long (2.9: 2.1); ratio of lower to upper interocular distance 0.85 (1.4: 1.2); clypeus about two times broader than long (1.2: 0.6); scape: length 0.7; maximum width 0.2; length of F1–F3: 0.17, 0.12, 0.17; diameter of F2: 0.2.
Etymology: The species name refers to the red orange colour of the integument.
Distribution: Bolivia; Brazil: Pará ( Fig. 76 View Figure 76 ).

Porter, C. Calmbacher’; BRAZIL: 1 female, ‘ DZUP \ 022524’ ‘ Coleção \ Campos Seabra’ ‘ Rio Acará \ Pará BRAZIL \ 24-VIII-1954 \ N. Cerqueira’, 2 females ( DZUP), idem except ‘022528’, ‘022525’.

1916); Rasmussen & Ascher (2008): 22.
Comments and diagnosis: Paratetrapedia albilabris is very similar to P. albopilosa , both having the posterolateral portions of the scutellum with numerous white plumose hairs ( Fig. 65). The female differs from P. albopilosa by T1 with dense minute punctures on vertical surface, and the male by lack of yellow marks on face, except for a thin yellow stripe on mid line of disc of frons; mandible, labrum, clypeus, and genal area completely dark brown in the male of P. albilabris . Male and female have T4 with only a short band of simple hairs, occupying less than one third of margin laterally; female T5–T6 with marginal band throughout its margin, and completely glabrous in males.
Distribution: Mexico; Costa Rica ( Fig. 76 View Figure 76 ).
Type material: Tetrapedia albilabris Friese , holotype male (ZMB), ‘ Costa Rica \ San Jose’ ‘ Tetrapedia \ albilabris \ M 1915 Friese det. 1915 Fr.’ ‘Type’ ‘Zool. Mus.\ Berlin’. The row of hairs on mid portion of S2 margin is slightly deformed in the holotype.
