Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.11; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.86 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.35 × as long as T2–8, approximately cylindrical, ventrolaterally rounded, uniformly, moderately pilose; T1LW 5.97; T1WW 1.29; spiracle on 0.47 of its length, distinctly prominent; median depression absent; lateral and median posterior depressions absent; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 3.12; T2WW 1.56; thyridium much longer than wide, without small circular depression just behind it; T2–8 minutely and very weakly coriarious, densely and uniformly pilose.

Metasoma: mostly blackish; anterior 0.4 dorsally and posterior 0.2 of T1, whitish; S1 whitish; T2–7 with apical, progressively wider, light yellow stripe; S2–6 anteriorly light brown, posteriorly whitish.

Variation. Fore wing 6.0– 7.5 mm. long. Specimen from Sinaloa yellow areas paler (211, 190, 113), with small posterior mark on pronotum and ventral 0.7 of epicnemium pale yellow, only with small black spot near anterior apex of sternaulus.

Comments. The males of M. antennator can be readily differentiated by the apical portion of the flagellum almost entirely white, with only one or two apical flagellomeres being entirely orange or blackish ( Fig. 260 View FIGURES 260–271. 260–261 ). This is a very distinctive character, exclusive of this species among Messatoporus , and apparently, among all Cryptinae . According to Kasparyan and Ruíz (2008), the female of M. antennator is very similar to M. tibiator , from which it can be differentiated by the hind second trochanter black (vs. orange, but sometimes with dorsoposterior blackish mark), posterior margin of mesopleuron black (vs. with distinct yellowish spot dorsally to hypoepimeron), and by having distinct sublateral crests on propodeum (vs. absent or very weak). In fact, only one female of M. antennator is known. It may eventually correspond to an unusual specimen of M. tibiator , particularly because it was collected at the same site of other females of the latter species (see “Distribution” for both species, Figs 278 View FIGURES 272–278. 272–273 , 297 View FIGURES 297–304 ). Also, at least some of the examined species of M. tibiator have distinct sublateral crests on propodeum. They are, thus, intermediaries between the original definition of M. antennator and M. tibiator . In that case, the female of M. antennator would still be unknown.

Biology. Unknown.
