Color. Head and mesosoma black and whitish, metasoma dark brown and whitish. Head: black; clypeus centrally, labrum, palpi basally, dorsal half of supra-clypeal area and orbital band widely interrupted at malar space, whitish (236,223,165); palpi apically, scape and pedicel ventrally, brownish orange; flagellum basally dark brown, blackish towards apex; f8–11 entirely white, f7 mostly white, f12 with small white spot. Mesosoma: black; pronotal collar, dorsal margin of pronotum, scutellar carina, posterior 0.6 of scutellum, axillar carina, postscutellum, tegula, subalar ridge, small central mark on mesopleuron, small spot at ventral margin of mesopleuron, dorsal division of metapleuron, dorso-posterior 0.3 of metapleuron and sublateral marks on propodeum, whitish; all coxae dark brown, hind one with small posterior whitish mark; fore and mid trochanters, femora and tibiae light orange (228,169,066); fore t1 light orange; mid t1 and fore and mid t2–4 dark fuscous, fore and mid t5 blackish; hind first trochanter light orange, second trochanter marked with light orange and dark brown; hind femur, extreme base of tibia, apical 0.75 of tibia, basal 0.4 of t1, ventral mark at t4 and t5, blackish; sub-basal 0.2 of hind tibia, apical 0.6 of t1 and t2–4, white. Metasoma: blackish; T1 whitish, dorsally dark brown at median 0.4; S1 light orange; T2–7 and S2–6 with posterior whitish stripes, T8 with lateral whitish stripe.

Male. Fore wing 8.30–9.63 mm long. Similar to female, except for the following: supra-clypeal area entirely yellowish; antenna with 29–31 flagellomeres; white band at flagellum distinct only dorsally; fore and mid coxae extensively marked with yellowish; fore and mid trochanters and femur yellowish, dorsally with longitudinal brown stripe; fore and mid tibiae whitish, basal 0.6 ventrally with longitudinal brown line; fore t1–4, basal 0.4 of mid t1 and mid t2–4 whitish; yellow mark at hind coxa more extensive; T1 laterally black.

Variation. Fore wing 8.70–10.60 mm long. Antenna sometimes with 29 flagellomeres. Older specimens present less extensive yellow marks, which seems to be due to discoloration of the specimen associated with its long age. This tendency was not observed in any other species, and may complicate species determination. The paratype specimen from Zamora, Ecuador, collected in 1970, lacks the yellow marks on mesopleuron, and has the remaining yellow areas less extensive than the holotype (collected in 1981). The specimen from Banos, Ecuador, collected in 1939, lacks most of yellow areas on head and mesosoma, which are represented only by reddish brown marks. Among the male specimens, these variations also occur. The color differences might represent “real” variation instead of effects due to collecting or age of specimen, but even so they would still be likely intra-specific variation. The species is recognized and defended as discussed below.

Comments. Messatoporus andinus can be recognized by the following combination of characters: mesopleuron with shallow depressions, one posterior to ventral 0.3 of epicnemial carina, covered with oblique and somewhat regular wrinkles, and one represented by a small pit dorsad to sternaulus midlength; scrobe moderately deep and covered with moderately strong wrinkles; metapleuron covered by the same wrinkling of propodeum, however less regular; posterior transverse carina propodeum more or less distinct, forming weak to moderately strong sublateral crests; fore wing crossvein 2Cu about 0.7 × as long as 2cu-a; cell 1+2Rs of moderate size, APH 0.93, crossveins 2r-m and 3r-m distinctly convergent; ovipositor slender, apically slightly depressed, dorsal valve without ridges, ventral valve with eleven teeth.
