Type species.

Parawroughtonilla hirsuta Maruyama, sp. n.

Etymology.

A combination of the Greek para-, meaning near, and Wroughtonilla Wasmann, 1899, a closely related genus. Gender, feminine.

Diagnosis.

This genus is rather similar to Togpelenys Kistner, 1989 in body shape and punctation of body surface, but may easily be distinguished from it by the smaller eyes, and the abdomen being densely covered with setae.

Description.

Body (Fig. 3) elongate, slightly flattened; surface of fore body strongly rugose, shining.

Head (Fig. 3) transverse, depressed above, widest at eyes that are large, less than 1/2 as long as head; clypeus truncate apically. Labrum weakly emarginate antero-medially, with 2 setae and 4 long setulae along anterior margin, with sparse pseudopores around lateral areas. Mandibles (Figs 6, 7) almost symmetric, gently curved, each apex acutely pointed; inner margin of left mandible (Fig. 6) with a small notch. Mentum (Fig. 8) trapezoidal, with several thick setae, with sparse pseudopores. Labium (Fig. 9) broad; prementum with a setal pore, in which seta is rather long, and 2 real pores in its inner side, with several pseudopores around real pores and base of medial seta; apodeme without median projection, with lateral projection short, curved apically; ligula long, each lobe with 2 large setula; labial palpus with segment I long and apically dilated; segment II 2/3 as long as I; segment III thin, narrowed apically, slightly shorter than II.

Pronotum (Fig. 3) slightly convex, with a broad longitudinal groove medially; sides weakly margined, i.e., superior marginal line somewhat obscured by rugose punctures continuing from disc. Mesocoxal cavity well margined; process of metaventrite narrow, pointed at apex.

Elytra (Fig. 3) apically widened, laterally with a pair of carinae that are not clear, with large rugose punctures.

Legs (Fig. 3) very long, thin; femora slightly narrowed apically; tibiae somewhat widened from around middle to basal 1/3, their bases constricted; tibiae somewhat thin.

Abdomen (Fig. 3) rather expanded, widest around segment IV; surface densely punctured, shining. Median lobe of aedeagus (Fig. 12) with apical lobe covered by exposed inner sac which is fused with apical margin of aedeagus and well sclerotized. Paramere with apical lobe slightly widened apically, somewhat constricted around middle.
