PARATETRAPEDIA HYALINATA SP. NOV.

( FIGS 66 , 77 , 87, 118, 151, 152 )

Comments and diagnosis: Paratetrapedia hyalinata is very similar to P. lugubris with regard to body size, colour, and shape. Paratetrapedia hyalinata possesses an omaular carina over less than upper half of mesepisternum, and the same pattern of pubescence as on sterna of P. lugubris . Paratetrapedia hyalinata differs from P. lugubris mainly by T4–T6 of males and females with marginal band of plumose hairs throughout the entire margin, and fore wing membrane dark brown with apical portion white infumate. The holotype is partially damaged, with margins of fore wings slightly torn, and most of pubescence of head and mesosoma absent.

Description

Holotype male: Body length: 10.5; maximum head width: 3.2; fore wing length (including tegula): 9.9. Colour. Integument mostly black. Mandible with one yellow spot on base; labrum and clypeus with yellow marks on lateral margins; scape reddish brown, with basal portion yellow; pedicel and flagellomeres reddish brown; genal area with one thin yellow stripe on lower portion. Wing membrane mostly dark brown infumate; fore wing membrane with apical third white infumate; veins and pterostigma dark brown; microtrichia dark brown. Tibial spurs dark brown. Pubescence. (pubescence of head and mesosoma mostly absent). Pubescence mostly dark brown. T4–T6 with dense marginal band of plumose hairs on entire margin; S2 with continuous row of simple setae; margin of S3 glabrous on mid portion, with long plumose hairs laterally. Legs with pubescence mostly black, with few sparse white plumose hairs on the distal half of the hind tibia. Integument sculpture. Clypeus with sparse coarse punctures (1–2 pd) intermingled amongst sparse minute punctures (> 2 pd); supraclypeal area with central portion mostly smooth, with some coarse punctures laterally (1–2 pd); disc of frons with heterogeneous punctures, with sparse coarse punctures (2 pd) intermingled amongst fine sparse punctures (1–3 pd); antennal scrobe with dense fine punctures (<1 pd). Mesoscutum and scutellum with dense fine punctures (1 pd), intermingled amongst sparse coarse punctures (> 1 pd); metapostnotum with heterogeneous punctures, contiguous coarse punctures (<0.5 pd) intermingled amongst dense fine punctures (1 pd); metapostnotum with fine lamellas adjacent to margin of metanotum; mesepisternum with dense coarse punctures laterally (0.5–2 pd). Structure. Lamella of pronotal collar acute throughout its length with lateral portions diverging from mesoscutum. Scutellum strongly biconvex, mid line sulcate. Hind basitarsus with acute tooth on anterior margin. Head about 1.18¥ broader than long (2.7: 3.2); ratio of lower to upper interocular distances: 0.8 (1.4: 1.8); clypeus about 1.5¥ broader than long (1.45: 0.95); scape: length 0.91; maximum width 0.25; length F1–F3: 0.23, 0.16, 0.25; diameter of F2: 0.21.

Paratype female: Body length: 11.1; maximum head width: 3.8; wing length (including tegula): 10.5. Colour. Similar to male, except for absence of yellow marks on terga and sterna. Pubescence. Mostly dark brown, except margins of sterna with pubescence pale white; mesoscutum and scutellum with very short dark brown pubescence; scutellum with one erect setae laterally (c. 0.14 mm in length); T4–T6 with marginal hair band throughout margin. Legs pubescence mostly black, except hind basitarsus with pubescence mostly white. Integument sculpture. Punctuation denser and finer than on males; clypeus and supraclypeal area with dense coarse punctures (0.5–2 pd); frons with dense fine punctures (0.5–1 pd), with few sparse coarse punctures on disc; mesoscutum and scutellum with dense minute punctures (0.5–1 pd), intermingled amongst sparse coarse punctures (0.5–3 pd); metapostnotum with dense to contiguous minute punctures (<0.5 pd), intermingled amongst coarse punctures on central portion (0.5– 2 pd). Mesepisternum laterally with dense coarse punctures (0.5–1 pd), intermingled amongst fine punctures (0.5–2 pd). Vertical surface of T1 with microsculpture of dense minute punctures; disc of T2–T6 with microsculpture of fine lines forming minute circles; marginal zone of terga with microsculpture of fine reticulated lines. Structure. Similar to male, except that scutellum weakly biconvex. Head about 1.3¥ broader than long (3.8: 2.9); ratio of lower to upper interocular distances: 0.88 (1.95: 2.2); clypeus about 1.8¥ broader than long (1.75: 0.95); scape: length 1.1, maximum width 0.25; length of F1–F3: 0.32, 0.17, 0.22; diameter of F2: 0.27.

Etymology: The species name refers to the milky hyaline apex of the fore wing membrane.
