Type species.

Henryognathus thomasi , new species.

Diagnosis.

Recognized by the elongate ovoid body, the moderately prognathous head, the pale tibiae with contrasting dark spots at the bases of the dark spines (Fig. 1A, B), the tarsal claws of moderate length, broad at base, bent medially, with a small, flaplike pulvillus just proximad of bend in claw, and the structure of the male genitalia, with elongate, slender, curving apical endosomal spines, the ventral spine conspicuously bifurcating at a point significantly proximal to the secondary gonopore (Fig. 2A). Body form, head shape, and tibial coloration similar to most Plagiognathus species, but proximal bifurcation of “ventral” strap of endosoma unlike the condition seen in Plagiognathus , as are the longer, more slender, curving apical spines ( Schuh 2001: figs 20-33).

Description.

Size moderate (Table 1). COLORATION (Fig. 1A, B): Pale in known species.

Surface and vestiture: Dorsum weakly granular, smooth, weakly shining. Vestiture of dorsum composed of reclining pale, golden-shining, simple setae.

Structure: Hemelytra sloping laterally, corial margins very weakly convex; frons tumid, clypeus visible from above. Tarsal claws similar to those in Plagiognathus (Schuh, 2001: figs 37C, 38D), of moderate length, broad at base, bent medially, with a small, flaplike pulvillus just proximad of bend in claw.

Genitalia (Fig. 2): Endosoma strongly twisted and bent medially, basal portion of moderate and uniform width; apical spines long, slender; ventral spine conspicuously bifurcating at a point significantly proximal to the secondary gonopore; endosoma with a broad rectangular flange proximal to secondary gonopore; secondary gonopore moderately large and strongly sclerotized, with a projecting sclerite proximally.

Phallotheca: L-shaped, with a broad posterolateral opening on distal portion. Left paramere short, anterior process with a strong subapical seta; right paramere elongate, parallel sided over most of length, with a fingerlike apex.

Female: Very similar in shape and proportions to male (Fig. 1B). Coloration as in male. Female genitalia: Not examined.

Etymology.

A combination of Henry (Thomas J. Henry) and -gnathus, from the Greek gnathos, jaw, in reference to the similarity with species of Plagiognathus .

Discussion.

Henryognathus falls within the diagnosis of Plagiognathus Fieber, as rendered by Schuh (2001), with the exception of the structure of the male genitalia.
