The Wharton Lab

Opius (Utetes) tubulatus Fischer, 1979: 294-296. Holotype female in AEIC.
Lorenzopius tubulatus: Van Achterberg and Salvo 1997: 192, key to species of Lorenzopius; Wharton et al. (2012): 62-64 (review of Lorenzopius).

Head with labrum partly exposed (Fig. 4); clypeus (Fig. 4) tall, slightly broader than high, flat or nearly so, not protruding from face in lateral view, ventral margin truncate; mandible without basal tooth or lobe, weakly narrowing apically; malar space distinct, malar sulcus deep, weakly curved; antenna long but broken in holotype (Fig. 1). Mesosoma with pronope absent; notauli narrow, deeply impressed at base, extending as shallow crenulate grooves about half length of mesoscutum, curving laterally at base to form marginal carina extending to tegula, marginal carina crenulate on medial side, midpit present (Fig. 5); scuto-scutellar sulcus rectangular, crenulate (Fig. 5); precoxal sulcus (Fig. 2) deep, long, crenulate throughout, extending dorsally to at least midpoint of pronotum; propodeum (Fig. 6) rugulose to granular rugose posteriorly, anterior transverse arms and median carina of a wide areola distinct anteriorly. Fore wing (Fig. 1) stigma discrete distally, nearly parallel-sided, slightly broader at r1, r1 arising distinctly basad midpoint of stigma and longer than width of stigma; m-cu postfurcal, entering extreme based of second submarginal cell; second submarginal cell weakly but distinctly narrowing distally; 2CUb arising slightly above middle of posterior margin of 1st subdiscal cell. Hind femur (Fig. 1) broadening distally, neither slender nor bilobed, predominantly dark brown, yellow ventrally and on basal 0.2. Metasoma with T1 exceptionally long and narrow (Fig. 6) about 4.2 x longer than apical width, roughly parallel-sided; T1 weakly strigose, mostly smooth (Fig 3), dorsal-lateral carina very short, weak, lateral carina longer but very weak, difficult to see; spiracle at apical 0.6; S1 extending nearly full length of T1 and fused to T1; dorsope and laterope absent; T2+3 mostly yellow, remainder of metasoma dorsally dark brown.
This species is readily distinguished from other Lorenzopius by the dark hind femur and the longer, narrower T1, which is about 3 x longer than wide in other known species.

Known only from the holotype collected at Portete de Tarqui, Ecuador (2900-3300 m).

Images were taken by Lauren Ward. We are grateful to David Wahl of the American Entomological Institute (AEIC) for extended 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.
