Parawroughtonilla hirsuta Maruyama, sp. n.

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

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.

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.

Leptogenys borneensis.

This species is similar to Togpelenys gigantea in general appearance, but distinguished from it by the smaller body, the dense setation on the body surface and the presence of a superior marginal line of the pronotal hypomeron. This species is found together with Leptogenonia roslii in the same host colony, and can be easily distinguished from it by the larger body and the longer and denser setation on the body surface.

Body (Fig. 3) color reddish brown, but head and elytra slightly darker. Head (Fig. 3) moderately covered with long erect setae; surface somewhat rugose. Antennae (Fig. 3) long; all segments longer than wide; segments III-X almost twice as long as wide; segment XI elongate. Pronotum (Fig. 3) longer than wide (width/length = 0.86), subparallel-sided, with anterior margin rounded, with posterolateral corners angled, produced laterally; surface moderately covered with long erect setae, which are poorly differentiated from macrosetae. Elytra (Fig. 3) moderately covered with long erect setae. Abdomen (Fig. 3) with sternites moderately covered with long erect setae, with tergite VIII (Fig. 10) rounded apically, with 9 macrosetae; sternite VIII (Fig. 11) rounded apically; tergite IX with 4 macrosetae; tergite X with 5 macrosetae postero-laterally.

Male: sternite VIII (Fig. 11) with around 18 macrosetae. Median lobe of aedeagus (Fig. 12) with short parameral crest; apical lobe curved near apex.

Female: sternite VIII with 14–16 macrosetae. Spermatheca (Figs 13–14) with basal part slightly dilated apically, twice curved near base and apex; apical part short.

Leptogenonia roslii Maruyama, sp. n.

A combination of the host ant genus name Leptogenys and “-nia” that is the end of a lomechusine genus name Myrmedonia Erichson, 1837, in the same manner as Aenictonia Wasmann, 1900 which is associated with Aenictus ants.

This genus is similar to Maschwitzia Kistner, 1989 in body shape and punctation of body surface, but may easily be distinguished from it by the smaller body, the head with post-ocular ridges (Fig. 5: arrow), the temples being convex and the shorter legs. The head capsule structure is similar to those of Aenictonia and Anommatochara Wasmann, 1915 but is distinguished from those genera by the elytra without a pair of medial carinae.

Body (Fig. 4) elongate, flattened; surface of fore body rugose, matte.

Head (Figs 4, 5) transverse, depressed above, with post-ocular ridges (Fig. 5: arrow), widest at temples that are quite convex; occiput convex, with a pair of small tubercules; eyes large, less than 1/4 as long as head; clypeus truncate apically. Labrum weakly emarginate antero-medially, with 3 setae and 3 long setulae along anterior margin, sparsely with pseudopores around lateral areas. Mandibles (Figs 15–16) almost symmetric, gently curved, each apex acutely pointed; inner margin of right mandible (Fig. 16) with a small notch. Mentum (Fig. 17) trapezoidal, with several thick setae, very sparsely with pseudopores. Labium (Fig. 18) broad; prementum with a setal pore, in which seta is very long, and 2 real pores in its outer side, with several pseudopores around base of medial seta; apodeme without median projection, with lateral projection short, curved apically; ligula long, each lobe with 3 large setula; labial palpus with segment I long and apically dilated; segment II 4/3 as long as I, with membranous notch; segment III thin, narrowed apically, slightly as long as II.

Pronotum (Fig. 4) slightly convex, with a broad longitudinal groove medially, its lateral lines convex as a pair of carinae, sides well margined and elevated, depressed along margins. Mesocoxal cavity well margined; process of metaventrite narrow, rounded at apex.

Elytra (Fig. 4) apically widened, laterally with a pair of carinae; postero-inner margin of elytron obliquely truncate.

Legs (Fig. 4) moderate in length; femora slightly narrowed apically near apex; tibiae somewhat widened from around middle to basal 1/3, their bases constricted; tarsi somewhat thin.

Abdomen (Fig. 4) slightly expanded, widest around segment IV, well convex above; surface densely punctured, matte; segments II-IV emarginated posteromedially; segments III and IV with a pair of large depressions around base, . Median lobe of aedeagus (Fig. 22) 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.

Leptogenys borneensis.

This species is similar to the members of the genus Maschwitzia but is easily distinguished from them by the smaller body and the shorter legs. This species is found together with Parawroughtonilla hirsuta in the same host colony, but it can be easily distinguished by the smaller body and the shorter and sparser setation on the body surface, especially by elytra lacking any setae.

Body (Fig. 4) color pale reddish-brown, but head, pronotal lateral margins, elytra and abdominal segments V-VI darker. Head (Figs 4–5) moderately covered with short recumbent setae; surface somewhat rugose. Antennae (Fig. 3) long; all segments longer than wide; segments III-X almost 1.5 times as long as wide; segment XI conical. Pronotum (Fig. 4) longer than wide (width/length = 0.88–0.91), with anterior margin truncate, constricted around basal 1/3, with posterolateral corners rounded, produced laterally; surface without setae. Elytra (Fig. 4) with surface moderately covered with short recumbent setae. Abdomen (Fig. 4) with sternites moderately covered with long recumbent setae, with tergites moderately covered with very short recumbent setae; tergite VIII (Figs 19, 21) with 7 macrosetae; sternite VIII (Fig. 20) rounded apically, with 8 macrosetae; tergite IX with 4 macrosetae; tergite X with 4 macrosetae postero-laterally.

Male: tergite VIII rounded apically. Median lobe of aedeagus (Fig. 22) with short parameral crest; apical lobe curved near apex.

Female: tergite VIII slightly truncate apically. Spermatheca (Fig. 23) with basal part almost straight but slightly curved at apex; apical part large, 1/2 as long as basal part.
