Diagnosis.

Holotype male. Labrum partly concealed by mandibles (Fig. 85); clypeus nearly twice as wide as tall, protruding in profile, ventral margin truncate to very weakly concave. Mandible with basal lobe, apically nearly parallel-sided. Malar space distinct, malar sulcus not evident except as a small impression adjacent eye. Antenna with 26 flagellomeres. Pronotum dorsally not readily visible in holotype. Disc of mesoscutum nearly bare, with a sparse row of setae between notauli and transscutal articulation; midpit completely absent; notauli weak, present as very short, unsculptured grooves on anterior declivity, not extending posteriorly onto disc of mesoscutum; supra-marginal carina between base of notaulus and tegula absent. Scuto-scutellar sulcus relatively narrow (Figs 86, 87), crenulate throughout. Precoxal sulcus indistinct, short, broad, very shallow, completely unsculptured. Propodeum granular rugose, without median carina anteriorly, moderately setose. Fore wing stigma long, curled in holotype, but appears to be very gradually tapered distally; r1 equal to or slightly longer than stigma width; second submarginal cell long, distinctly narrowing distally; m-cu widely antefurcal (Fig. 63, 65); 2CUb arising about middle of hind margin of first subdiscal cell, 2cu-a absent, first subdiscal cell broadly open at posterior-distal corner. Hind coxa smooth; hind femur very long, slender, weakly bilobed. T1 (Figs 63, 65, 86, 87) completely striate, the striae curving medially from basal-lateral area adjacent dorsal tendon attachment, completely obscuring dorsal and lateral carinae; dorsope and laterope absent; T1 spiracle indistinct, situated posteriad midlength of T1; T1 nearly parallel-sided, 2.1 × longer than apical width; S1 appears fused to T1; S1 0.5 × length of T1.

Remarks. This species is very similar to Tubiformopius tubibasis , but differs in having a little more of the labrum exposed between the apex of the clypeus and the tightly closed mandibles. The hind coxae are yellow in Tubiformopius tubigaster and distinctly infumate in Tubiformopius tubibasis . Both species were described from Ecuador.
