Metasoma: T1 pale yellow, dorsally orange at median 0.3; S1 orange; anterior margin of T2 dark brown, anterior 0.75 orange, posterior 0.25 pale yellow; S2 pale yellow; T3–6 basally blackish, medially dark orange, posterior 0.4 yellow; S3–5 dark brown, with narrow posterior pale yellow stripe; T7–8 and S6 pale yellow.

Male. Unknown.

Variation. Antenna sometimes with 28 flagellomeres; posterior part of pronotum sometimes marked with orange and blackish; subalar ridge bright to pale yellow; mesosternum sometimes dark orange; hind coxa sometimes with blackish spot; median mark on T1 sometimes pale orange; T2 sometimes anteriorly blackish; propodeum with an orange area between black and yellow areas; anterior area of propodeum sometimes partially orange; mesosternum just ventral to sternaulus either black or with small yellow areas.

Comments. Messatoporus versicolor is one of the most distinctive species of Messatoporus , both in general morphology and color patterns. It shows structural similarities to M. advenus sp. nov., from which it can be readily isolated by the body extensively marked with orange, pale yellow and black (vs. almost entirely orange). Messatoporus versicolor have the pronotum and mesopleuron mostly pale yellow, mesosternum and anterior area of propodeum black and T3–7 black with posterior pale yellow stripes; all of those areas are mostly or entirely orange in M. advenus . The two species can be additionally isolated by the posterior transverse carina complete and forming distinct sublateral crests in M. versicolor (vs. medially interrupted and forming very weak crests in M. advenus ).

Biology. Unknown.

Etymology. From the Latin versicolor , meaning “of various colors”; in reference to its intricate color pattern.

Material examined. 4 ♀. Holotype ♀ from Colombia, Boyacá, SFF Iguaque , 2820 m, 17.III–1.IV.2000, Malaise trap, PReina. Pinned. Extreme tip of both fore wings ripped; otherwise in good shape.
