( FIGS 44, 71 View Figure 71 , 84 View Figures 77–84 , 100, 130 View Figures 129–137 , 175, 176 View Figures 171–184 )

Comments and diagnosis: Paratetrapedia mexicana is distinguished by female prementum with numerous long curved setae, male S2 with continuous row of setae and posterior margin of S3 widely concave and covered by short plumose hairs, male and female T4–T6 with marginal hair band occupying whole margins, male hind basitarsus with one conspicuous tooth on proximal third of anterior margin and metapostnotum with coarse punctures intermingled amongst fine punctures.


Holotype male: Body length: 7.8; maximum head width: 2.75; fore wing length (including tegula): 8.9. Colour. Integument mostly dark brown; mandible pale yellow with apex black; labrum, clypeus, and supraclypeal area pale yellow; paraocular area with wide yellow stripe; scape pale yellow; pedicel and


flagellomeres pale brown ( Fig. 44). Wing membrane dark brown infumate; apical third of fore wing membrane slightly pale; microtrichia dark brown; veins and pterostigma dark brown. Tibial spurs white; mediotarsus, distitarsus, and claws pale yellow. Pubescence. Mostly dark brown, almost black. Scape with long dark brown hairs on inner face, about 0.01 mm in length. Mesoscutum and scutellum with short dark brown plumose pubescence; metapostnotum with short plumose hairs, about 0.06 mm in length. T4–T6 with marginal band of dense plumose dark brown hairs throughout its margin; margin of S2 with continuous row of simple erect black setae; S3 deeply concave in ‘U’ shape, covered by dense short plumose pubescence ( Fig. 21 View Figures 18–23 ); S4 and S5 typical of genus; S6 with sparse pubescence on disc and two conspicuous rows of stout plumose hairs on margins laterally, apex bordered by short plumose hairs. Pubescence of legs mostly dark brown; mid basitarsus with dense dark brown pubescence. Integument sculpture. Clypeus with dense coarse punctures (1 pd); supraclypeal area with coarse punctures (1 pd), with smooth and shiny integument amongst punctures; frons with sparse coarse punctures (2–3 pd); antennal scrobe completely smooth. Mesoscutum with fine dense punctures (<0.5 pd) intermingled amongst sparse coarse punctures (> 2 pd); metapostnotum with sparse fine punctures (2 pd); transition zone between metapostnotum and propodeum smooth and shiny; mesepisternum with sparse fine punctures (3 pd). Structure. Lamella of pronotal collar acute throughout its length. Disc of scutellum weakly convex, almost flat. Hind basitarsus with acute tooth on anterior margin. Head about 1.17¥ broader than long (2.75: 2.35); ratio of lower to upper interocular distance: 0.87 (1.26: 1.44); clypeus about 1.7¥ broader than long (1.15: 0.65); scape, length 0.6; maximum width 0.2; length of F1–F3: 0.2, 0.17, 0.25; diameter of F2: 0.22.

Paratype female: Body length: 8.7; maximum head width: 2.9; fore wing length (including tegula): 8.5. Colour. Similar to male, except for absence of pale yellow marks on face, with faint yellow mark on lower paraocular area; tarsomeres 2–4 orange yellow. Pubescence. Similar to male; except for conspicuously longer simple setae on lateral portions of scutellum, c. 0.42 mm in length; metapostnotum with short plumose setae, c. 0.16 mm in length; T4–T6 with marginal hair band occupying whole margin. Integument sculpture. Similar to male except for frons with sparse fine punctures (2 pd); metapostnotum with sparse fine punctures (2 pd) intermingled amongst sparse minute punctures (2 pd). Structure. Lamella of pronotal collar with lateral portions conspicuous obtuse. Scutellum disc weakly convex, almost flat. Head about 1.2¥ broader than long (2.9: 2.25); ratio of lower to upper interocular distance: 0.84 (1.37: 1.62); clypeus about 2.1¥ broader than long (1.27: 0.6); scape: length 0.8, maximum width 0.17; length of F1–F3: 0.25, 0.12, 0.17; diameter of F2: 0.22.

Variation: The wing membrane can be completely brown infumate or with apical portion pale infumate.

Etymology: The species name refers to the country of origin, Mexico.

Distribution: Mexico: Jalisco, Morelos ( Fig. 71 View Figure 71 ).
