Color. Head, mesosoma and metasoma black with light yellow marks. Head: black; clypeus, mandible except apex and ventral margin, mouthparts, supra-clypeal area and complete orbital band, light yellow (229, 208, 109); f5–9 entirely white, f4 apically white and f10–15 with dorsal basal white marks. Mesosoma: black; collar, dorsal margin of pronotum (wider at posterior 0.5), subcircular spot on mesoscutum, scutellar carina, scutellum, axillar carinae, postscutellum, tegula, subalar ridge, central mark on mesopleuron, mesosternum except posterior lateral spot, dorsal division of metapleuron, most of metapleural triangle, metapleuron except anterior margin and posterior spot and arc-shaped mark on propodeum, light yellow; fore and mid coxae and first trochanters light yellow, coxae with posterior and apical dark brown marks, trochanters with basal dark brown marks; fore and mid second trochanters, femora, tibiae and tarsi light orange (222, 132, 054), basal mark at second trochanters and both t4–5, blackish; hind coxa light yellow with three longitudinal stripes, anterior one extending on basal 0.5, lateral one reaching coxa apex and posterior one extending on basal 0.8; hind first trochanter light yellow with basal blackish mark; second trochanter and femur light orange, second trochanter with basal black mark; hind tibia bright yellow (235, 208, 064), apically orangish; extreme apex of hind tibia, tibial spurs and basal 0.4 of t1, dark brown; apical 0.6 of t1 and t2–5, whitish. Metasoma: black; anterior 0.5 and posterior 0.2 of T1, light yellow; T1–7 with posterior bright yellow stripes, progressively wider and occupying lateral areas towards apex, T8 only laterally yellow; S1–7 yellow, S2–5 with anterior dark brown areas.

Male. Fore wing 5.69–9.42 mm long. Generally similar to female, except for the following: scape ventrally light orange, scape dorsally and pedicel dark brown; light yellow areas at collar and dorsal margin of pronotum connected; area over notaulus light yellow; fore and mid coxa without posterior black marks; hind second trochanter almost entirely dark brown; apex of hind femur with dark brown mark; basal 0.5 of hind tibia whitish, apical 0.5 blackish.

Variation. Fore wing 6.69–10.39 mm long. Malar space sometimes partially light yellow; antenna with 21–23 flagellomeres; mesoscutum laterally sometimes with longitudinal light yellow dash; mid tarsus sometimes entirely fuscous. White marks at f10–15 stronger and connected at Mexican specimens. Light orange areas sometimes bright orange (213, 110, 052); dark brown marks at hind tibia and tarsus sometimes blackish; median depression on T1 weak to strong.

Comments. Messatoporus compressicornis is part of a group of four very close species, which apparently form a monophyletic group (see Analysis 2). Along with the recovered synapomorphies, species of that group are generally similar in size and color pattern, and share features like flagellum subapically strongly flattened, postscutellum yellow and T7–8 much longer than T5–6. Among these species, M. compressicornis can be differentiated from M. nigriscapus sp. nov. by having hind femur entirely orange (vs. deep yellow, dorsal face black); mandible basally yellow (vs. entirely black); orbital band complete (vs. shortly interrupted at dorsal margin of eye); collar yellow (vs. black); thyridium about as wide as long (vs. much wider than long); and ovipositor dorsal valve with five moderately strong ridges (vs. four). It can be isolated from both M. keraiopetalus sp. nov. and M. depressifrons sp. nov. by the hind femur entirely orange (vs. ventrally black, dorsally deep yellow); fore and mid femora entirely orange (vs. dorsally with strong longitudinal brown stripes); ovipositor dorsal valve with five moderately strong ridges (vs. four); supra-antennal area with slight median carina (vs. median carina indistinct, represented only by a smoother area or depression); and mesosternum medially without transverse wrinkles (vs. with short transverse wrinkles).

Biology. One specimen from Plummers Island, Maryland, was reared from Trypoxillon collinum rubrocinctum ( Crabronidae ). The species is also recorded in the literature attacking Ancistrocerus tuberculocephalus sutterianus Saussure ( Vespidae , Eumeninae). One paratype from Thomasville, Alabama, was collected on a Quercus sp. Many specimens were collected in urban or rural areas, what may indicate that the species can occupy areas with significant anthropogenic disturbance. Dozens of specimens were collected in fruitfly traps or Steiner traps at Florida during the 1952–1971, in Citrus grove and yards with Citrus trees as part of a monitoring programme for medfly. One specimen from Jacksonville was collected on x Citrofortunella mitis ; one specimen in a soybean field; and one specimen on Hibiscus sp. Some specimens were also collected in a green area behind the Doyle Conner Building, Gainesville, Florida Department of Agriculture. In the material from these collecting events, M. compressicornis was by far more common than the sympatric species M. discoidalis .

Distribution. Widely distributed throughout eastern USA and Mexico ( Fig. 313 ). In the USA, it reaches from Connecticut in the north to southern Florida, and west until Missouri. In Mexico it was recorded from several sites on the eastern coast. It was not collected in Texas, which would seem to be a natural transition from southeastern USA to northern Mexico. Specimens of M. discoidalis , however, have been collected at many sites in Texas; the absence of specimens of M. compressicornis may indicate that M. compressicornis is really absent in the extreme south of the USA. Messatoporus compressicornis occurs in sympatry with M. discoidalis in all of its distribution, but it seems not to overlap its distribution with its close Central American species.
