description: 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).
