Lamnatibia andina Palacio & Sääksjärvi sp.n.

( Fig. 2 )

Holotype female. Mandibles strongly narrowed; malar space 1.25 times as long as basal mandibular width, with a band of fine coriaceous sculpture extending from eye margin to mandibular base; clypeus large, polished and with scattered setiferous punctures; lower face more or less transverse, about 1.3 times as broad as high (from supraclypeal suture to level of insertion of antenna) and polished; genae rather wide behind eyes; lateral ocellus separated from eye margin by about 1.2 times its own diameter. Occipital carina completely absent. Mesoscutum smooth and polished, with isolated hairs on median lobe centrally; mesopleuron smooth and polished, glabrous, except for ventral part and mesosternum which are densely pubescent; metapleuron smooth and polished. Propodeum fairly evenly rounded, slightly declivous posteriorly, smooth and polished, except for scattered punctures behind the spiracle just above the metapleural carina. Fore wing cu-a opposed to base of Rs & M; base of 1m-cu separated from Cu1a by a distance slightly greater than length of Cu1b. Tergite 1 approximately 1.78 times longer than their maximum width, with a weak longitudinal impression in middle dorsum, lateromedian longitudinal carinae present on anterior 0.2 of segment, and with lateral carina weak but discernible more or less its entire length; tergites 2–4 smooth and polished, with some shagrening centrally.

Head black with clypeus whitish; mandibles whitish with apex blackish; antennae blackish brown at base, becoming darker towards apex. Mesosoma predominantly orange yellow, with most of propodeum black; metapleuron and apex of propodeum whitish. Front and middle legs with coxae and trochanters whitish, femur a little more yellowish with a longitudinal blackish stripe on ventral surface, tibiae yellowish with a brownish staining at base, tarsus brownish black; hind legs with coxa brownish yellow with apex whitish, femur and tibia brownish, tarsus brownish black. Wings hyaline, pterostigma blackish. Metasoma black with white bands, tergites 1 to 6 with apical and lateral bands, tergites 7 and 8 whit white only laterally. Ovipositor brownish, sheaths black.

Variation. The paratype specimens differ basically in the coloration of hind legs; the hind coxa, femur and tibia ranges from yellowish brown to almost black, and the hind coxa sometimes has a dorsal whitish spot. Such variation apparently is not correlated with the geographic distribution of specimens.

Male. Unknown.

Etymology. The specific name refers to the Andean distribution of the species.
