Tiphia perubra Allen 1972

Tiphia (Tiphia) perubra

This species which possesses a strong transverse carina on the first tergum, and lacks a transverse carina on the dorsal pronotum and a groove on the hind basitarsus, runs in the key to the couplet with T. iquitosa. It differs from T. iquitosa in having a much more closely punctate front and dorsal pronotum, and a more sparsely punctate abdomen.

HOLOTYPE.—♀; Peru-Brazil frontier, 14–II–1928, F 6007 (II. Bassler) (AMNH).

FEMALE.—Front to level of lowest ocellus with contiguous punctures separated only by narrow ridges. Cheek with mat of coarse, white hair. Mandible without preapical denticle.

Dorsal pronotum with only trace of transverse carina at humeral angle; punctures everywhere as closely spaced as those of front. Scutum with anteromedian escarpment not connected with notaulices. Mesopleuron broadly shagreened, with coarse punctures of first-degree density; subtegular patch of microsetae as wide as tegula. Hind tibia on inner face strongly ridged. Hind basitarsus without groove. Tegula broadly shagreened; without groove on outer margin. Forewing densely infuscate; stigma separated by more than its length from basal vein; radius with rudimentary spur on first section, but without terminal spur; the area of the first cubital cell is 17.0 times that of the stigma.

Areola of dorsal propodeum with its sides slightly sigmoid and convergent, its length about 3 times apical width. Tergum 1 with double-arced transverse carina, not defining a coarsely sculptured area; preapical band of very small, widely separated punctures, not impressed, poorly defined and about 2 punctures wide. Terga 3 and 4 sparsely and irregularly punctate, with broad impunctate apices which are medially about 6 times diameter of adjacent punctures. Pygidium on basal half; impunctate apex scarcely wrinkled and shagreened almost to its tip.

Length 12.2 mm.

MALE.—Unknown.
