Paratetrapedia (Paratetrapedia) duckei ; Rasmussen & Ascher, 2008: 45.

Comments and diagnosis: Paratetrapedia duckei is most clearly distinguished by lamella of pronotal collar with lateral portions low and obtuse in dorsal view ( Fig. 20 View Figures 18–23 ), conspicuously acute only on mid third, and male S3 not deeply concave in ‘U’ shape ( Fig. 29 View Figures 24–29 ). The male has the same pattern of pubescence on terga and sterna found in P. flavipennis , with two small rows of erect setae on mid portion of S2, and S3 mostly glabrous with only a row of simple setae slightly interrupted in mid portion ( Figs 28, 29 View Figures 24–29 ). This species is very similar structurally to P. flavipennis , differing only in the pattern of colour on mesoscutum, wings, and genal area, and smaller body size. Paratetrapedia duckei has the disc of mesoscutum dark brown and lateral portions orange yellow, and two thin yellow stripes on disc and lateral margins ( Figs 55, 56); genal area dark brown with thin yellow stripe. Paratetrapedia duckei exhibits considerable variation in colour pattern with dark forms in the western portion of its distribution and pale forms in the eastern portion.

Redescription: Male (redescription of holotype of Chalepogenus xanthaspis Cockerell ). Body length: 8.7; maximum head width: 2.6; fore wing length (including tegula): 8.7. Colour. Integument bicoloured (brown and yellow), mostly yellow; paraocular area with wide yellow stripe obtuse on upper portion; frons, upper paraocular area and vertex with dark brown integument; frons with yellow stripe on mid line (width about 0.5–1.25 ¥ F2 diameter); genal area dark brown with thin yellow stripe along ocular margin (width about 0.6 ¥ F2 diameter); scape yellow; pedicel and flagellomeres orange yellow. Mesoscutum with two thin yellow stripes on disc and lateral margins, slightly enlarged on mid portion ( Fig. 56); mesoscutum with disc reddish brown and lateral portions orange yellow; axilla brown; wing membrane yellow infumate with microtrichia yellow; fore wing dark brown on apical third because of dense brown microtrichia; veins and pterostigma orange yellow; hind basitarsus weakly dark brown; tibial spurs pale yellow. Terga orange yellow, with marginal zone dark brown. Pubescence. Mostly yellow, except marginal hair bands of T2–T4 and hind basitarsus with pubescence dark brown. Scutellum with long erect simple setae about 0.12–0.19 mm in length; metapostnotum with short plumose hairs, c. 0.12 mm in length. T4 with marginal hair band almost complete on whole margin, shortly interrupted on mid portion; T5–T6 with marginal band of plumose pale yellow hairs throughout its margin; S2 with two short rows of setae on mid portion; S3 with row of short simple setae, slightly interrupted on mid portion; S6 with two rows of stout plumose setae on margins laterally and short plumose hairs on margin of apex. Integument sculpture. Clypeus with sparse coarse punctures (0.5–2 pd), intermingled amongst sparse minute punctures (2 pd); supraclypeal area with disc mostly smooth and lateral portions with dense coarse punctures (0.5–1 pd); disc of frons mostly with sparse coarse punctures (<0.5–2 pd); antennal scrobe with fine dense punctures (0.5 pd). Mesoscutum with fine dense punctures (<0.5 pd) intermingled amongst sparse coarser punctures (2 pd); metapostnotum with dense minute punctures on lateral portions (1 pd), and coarser punctures on disc (0.5–1 pd); transition zone between metapostnotum and propodeum with smooth and shiny surface; mesepisternum mostly with sparse coarse punctures (2 pd). Structure. Pronotal collar with lamella obtuse and low on third lateral portions, and central third of lamella acute in dorsal view. Scutellum disc convex. Head about 1.15¥ broader than long (2.6: 2.3); ratio of lower interocular distance to upper interocular distance: 0.9 (1.2: 1.4); clypeus about 1.5¥ broader than long (1.16: 0.73); scape: length 0.72, maximum width 0.21; length of F1–F3: 0.7: 0.23: 0.16: 0.23; diameter of F2: 0.26.

Variation: Besides the variation in body colour mentioned above, specimens from the western portion of the distribution ( Brazil: Rondônia, Mato Grosso; Peru) have pubescence of hind leg mostly dark brown and yellow stripe on genal area interrupted on mid third, whereas most specimens from the northern and eastern portions ( Brazil: Amapá, Amazonas, Manaus , Pará ; Guyana, French Guiana) have pubescence of hind leg orange yellow and yellow stripe on genal area entire along eye margin. In addition, some females from Amapá and Pará have microsculpture of minute punctures on T1 , and one specimen from Rondônia has this microsculpture on T2 T3 .

Distribution: Bolivia; Brazil: Acre, Amapá, Amazonas, Mato Grosso, Pará, Rondônia; French Guiana; Guyana; Peru; Suriname ( Fig. 74 View Figure 74 ).

Comments and diagnosis: Paratetrapedia flavipennis differs from the remaining species in the group mainly by male S3 not deeply concave in ‘U’ shape ( Fig. 29 View Figures 24–29 ), and lamella of pronotal collar with lateral portions more obtuse and lower than in the remaining species ( Fig. 20 View Figures 18–23 ). Paratetrapedia flavipennis is structurally identical to P. duckei , but differs mainly by mesoscutum and genal area completely orange yellow and larger body size (> 9.0 mm in length).

Redescription: Holotype (female). Body length: 9.8; maximum head width: 3.0; fore wing length (including tegula): 8.7. Colour. Integument mostly orange yellow. Paraocular area with wide yellow stripe with upper portion obtuse; mandibles, labrum, and clypeus yellow; frons, upper paraocular area, and vertex reddish brown; frons with thin yellow stripe on mid line; scape yellow, pedicel and flagellomeres orange yellow; genal area completely orange yellow. Mesoscutum completely orange yellow, with two thin yellow stripes weakly faint on disc. Wings with membrane yellow infumate; apical portion of fore wing membrane dark because of dark brown microtrichia; veins and pterostigma orange yellow. Tibial spurs pale white. Margins of terga weakly dark brown. Pubescence. Mostly orange yellow. Scutellum with long simple erect setae, about 0.12–0.26 mm in length; metanotum with short plumose hairs, about 0.10 mm in length; metapostnotum with dense short plumose hairs, c. 0.08 mm in length. T4–T6 with marginal band of short simple hairs throughout margin. Row of setae on sternal margins sinuated in ‘V’ shape on mid portion (as in Fig. 32 View Figures 30–33 ). Integument sculpture. Clypeus and supraclypeal area with dense coarse punctures (<0.5 pd); disc of frons with dense coarse punctures on mid portion (<0.5–2 pd). Mesoscutum with dense fine punctures (<0.5 pd), intermingled amongst sparse coarser punctures (1–3 pd); lateral portions of metapostnotum with dense fine punctures (0.5–1 pd), with few coarser punctures on disc. Mesepisternum laterally with sparse coarse punctures (2 pd), omaular area with denser punctures (0.5–1 pd). Structure. Lamella of pronotal collar obtuse throughout its length. Scutellum disc almost flat. Head about 1.2¥ broader than long (3.0: 2.5); ratio of lower to upper interocular distance: 0.87 (1.4: 1.6); clypeus about 1.6¥ broader than long (1.27: 0.77); scape: length, 0.8, maximum width, 0.2; length of F1–F3: 0.26, 0.17, 0.17; F2 diameter: 0.2.

Variation: The holotype of P. flavipennis has fore wing membrane yellow infumate with one thin band of dark brown microtrichia on posterior margin; width of band of microtrichia about 1.0 ¥ F2 diameter. Only one specimen from Tefé (Amazonas) has the same pattern of microtrichia on fore wing of the holotype. The remaining specimens examined have a broader band of microtrichia dark brown on apical portion of fore wing (c. 3 ¥ F2 diameter) .

Distribution: Brazil: Amazonas; Peru ( Fig. 74 View Figure 74 ).

Type material: Tetrapedia flavipennis Smith ; holotype female (BMNH), ‘Type\ H.T.’ ‘B.M. Type\ Hym.\ 17.B.884\ Tetrapedia \ flavipennis \ (Type) Sm.’ ‘58\ h\\ Ega’.
