Loxopus venezuelanus Santos et Aguiar , sp. nov. (Figures 4D, 6D, 8H)

Female

Fore wing 4.70 mm. Head. CWH 1.79; CWW 1.79. MLW 1.53; MWW 0.53; MSM 0.58. Median line on supra-antennal area faint. Mesosoma . Pronotum distinctly striate on ventral 0.5 and posterior margin of collar, elsewhere coriarious. Scutellar carina in lateral view distinct on about 0.3 of scutellum. Subalar ridge moderately wide, elliptic; epicnemial carina restricted to ventral 0.7 of mesopleuron, somewhat uniformly arched. Transverse furrow at base of propodeum with distinct striae. Metapleuron coriarious; juxtacoxal carina present, short and delicate; pleural carina distinct, delicate, covered by wrinkles. Fourth tarsomeres lateral lobe 3.3 × as long as mesal lobe. Anterior margin of propodeum medially approximately straight; SWL 1.63; posterior transverse carina complete, medially distinctly arched, sublaterally forming distinct crests. Fore wing vein 1-Rs + M approximately straight; crossvein 1m-cu uniformly curved, slightly shorter than 1-Rs + M; crossvein 1cu-a arising opposite base of 1M + 13Rs; veins 2cu-a and 2-Cu aligned, continuous; bulla of crossvein 2m-cu placed ventrally; APH 0.48; AWH 1.05. Hind wing vein 2-1A entirely absent; HW1C 1.50. Metasoma. T1LW 2.00; T1WW 2.21; T1 ventrolaterally approximately cylindrical; laterally before spiracle and dorsally coriarious, elsewhere smooth; dorsolateral carina complete but delicate; ventrolateral carina distinct, stronger apically. T2LW 0.81; T2WW 2.14; T2–8 coriarious, mostly sparsely pilose, T3–8 with distinct pilosity laterally, pilosity on T6–8 also distinct dorsally. OST 0.62; ovipositor straight; dorsal valve without nodus, preapical notch indistinct, ventral valve tip with 10 oblique ridges ( Figure 6D ).

Colour. Head brown and light yellow, mesosoma mostly ferruginous, metasoma dark brown and whitish. Head: brown; mandible except apex, palpi, clypeus, malar space, supra-clypeal area and complete orbital band, light yellow (228,209,117); scape light orange (207,129,052); supra-clypeal area with lateral brownish marks; pedicel and flagellum light brown, pedicel with dorsal light yellow spot [antenna broken at basal third, white band not visible]. Mesosoma : ferruginous (148,073,025); propleuron, collar, tegula, subalar ridge, small mark on dorsal division of metapleuron, metapleuron near hind coxa and small transverse marks over propodeal crests, light yellow (225,212,122). Legs mostly fuscous (175,113,050); fore and mid coxae and all trochanters, whitish; hind coxa whitish laterally with broad brown mark, anteriorly to the mark ferruginous, posteriorly whitish; hind trochantellus, base and apex of femur with brownish marks; all t5 blackish. Wings hyaline, fore wing with brownish spot covering apical portions of cells 2 + 3M and 1 + 2R. Metasoma: T1 mostly ferruginous, dorsally brownish at subapical portion, apically light yellow; S1 ferruginous; T2 brown, T3 whitish, anteriorly with large brown spot; T4–6 blackish, T7–8 dorsally whitish, laterally dark brown; S2–4 whitish, S2 with lateral brown mark; S5– 6 brown. Ovipositor reddish orange, its sheaths brown.

Male

Unknown.

Comments

Similar to L. duckei , from which it can be differentiated by the orbital band complete (versus widely interrupted and dorsal portion of gena); subalar ridge moderately wide, elliptic (versus narrow, dash-like), and bright yellow (versus ferruginous or whitish); transverse furrow at base of propodeum with distinct striae (versus almost indistinct); juxtacoxal carina present (versus absent); and T1 anteriorly orange (versus blackish).

Etymology

Latinized form of ‘of Venezuela’; in reference to its type locality in Venezuela .

Material examined

Holotype ♀ from VENEZUELA, San Esteban , nr. Puerto Cabello, 20 January 1940, P.J. Anduze ( AEIC). Apical two thirds of both antennae and right hind leg apicad of trochanter missing; otherwise in good shape.

Distribution

Venezuela ( Figure 8H).
