Olcotomaspis Lallemand, redefined.

Olcotomaspis Lallemand, 1949: 29 .

Hyalotomaspis Lallemand, 1949: 30 (subgenus, stat.nov.)

Diagnosis. Resembling the old-world Phymatostetha but with antennal sensillae not flattened and quite different male genitalia (compare to figures of Phymatostetha in Metcalf & Horton 1934).

Description. Subgenital plates separate to (but not beyond) base as in Tomaspisina, but with low, spiculate basal lobe; theca strongly laterally compressed, rcurved, tip truncate, with spiculate anterior angle and long pair of erect processes prominently toothed on outer edge (Carvalho & Webb 2005, figs 186–187).

Included taxa: Hyalotomaspis Lallemand is an autapomorph, a single species with the tegminal venation prominent on hyaline wings but having all the other characteristic features of the type-species of Olcotomaspis including the characteristic orange pattern on the notum (compare Fig. 7 A to fig. 557 in Carvalho & Webb 2005). Three species belong to this genus: Olcotomaspis versicolor (Lallemand) and two new combinations from Tomaspis: clarissa Jacobi (type-species of Hyalotomaspis) and Tomaspis laterinotata Fowler, known only from the female holotype. The antennal sensilla of the latter could not be ascertained as the postpedicels on both sides of the head are appressed to the gena (Fig. 17 C).
