Tubiformopius tubibasis (Fischer)

Taxonomic History / Nomenclature
Opius (Opius) tubibasis Fischer, 1978: 163-165. Holotype female in AEIC.
Opius (Opius) tubibasis: Yu et al. 2005, 2012 (electronic catalogs).
Tubiformopius tubibasis: Wharton et al. (2012): 76-77.
Van Achterberg and Salvo (1997) suggested the possibility that tubibasis might belong in Lorenzopius despite the absence of a midpit on the mesoscutum. The subsequently described Tubiformopius is a better fit because tubibasis is nearly identical to the type species of Tubiformopius, Tubiformopius tubigaster, especially with respect to critical features of mesosomal sculpture and fore wing venation in addition to the shape of the mandible.
Diagnosis and Relationships
Holotype female. Labrum completely concealed by mandibles (Fig. 3); clypeus tall, narrow, weakly protruding in profile, ventral margin truncate. Mandible with weak basal lobe, apically nearly parallel-sided. Malar space distinct, malar sulcus not evident except as a small impression adjacent eye. Antenna with 24 flagellomeres. Pronotum dorsally not readily visible in holotype. Disc of mesoscutum nearly bare, with a very sparse row of setae between notauli and transscutal articulation; midpit absent or nearly so, with faint indication of a depression when viewed in certain angles; notauli weak, present as short, weakly sculptured 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 as in O. tubigaster, crenulate throughout. Precoxal sulcus barely visible as a short, broad, very shallow, completely unsculptured indentation. Propodeum granular rugose, without median carina anteriorly, moderately setose. Fore wing (Fig. 1) with stigma long, curled in holotype, but very gradually tapered distally; r1 equal to or slightly longer than stigma width; second submarginal cell long, distinctly narrowing distally; m-cu widely antefurcal; 2CUb arising slightly below 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 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 at 0.65 length of T1; T1 parallel-sided, 2.5 x longer than apical width; S1 appears fused to T1; S1 0.6 x length of T1.

We are grateful to David Wahl of the American Entomological Institute for loan of the holotype. Matt Yoder provided considerable assistance with databasing issues, and our use of PURLs (http://purl.oclc.org) in this regard follows the example of their use in publications by Norm Johnson.
