Iba Schmidt, 1920:49 .

Type-species by monotypy: I. cuneata Schmidt, 1920 .

Parahindoloides Lallemand, 1951:88 , stat.nov. (subgenus). Type-species: P. lumuana Lallemand, 1951 .

Distribution. Southeast Asia.

Diagnosis. Resembling Clastoptera , but lacking transverse carina on crown; head depressed, narrower than pronotum; face broadly sulcate with diamond-shaped median depression ( Fig. 4 A); pronotum obliquely striate either side of longitudinal carina ( Fig. 6 B); antennal ledge with 2 setae in a vertical row before antennal pit, or 3 arranged in a triangle; postpedicel armed with sensilla in narrow hollow behind arista scarcely wider than base of arista, flanked with sharp-edged ridges converging on pit containing coeloconic sensilla (Figs. 24D–E); tegmina with costa with transverse wedge-shaped fold or "cunea” just before anteapical cells, small bulla basad of “cunea” and large bulla across subcostal cells ( Fig. 4 B). Ovipositor with 2nd valvulae 0.6–1.0 mm long, similar to those of Clastoptera , with 1–3 dorsal teeth ( Figs 10 A–C).

Included taxa. Three species, two in the nominate subgenus from the Philippines, and a third species in subgenus Parahindoloides from Borneo.

Remarks. Antennal and genital characters indicate that Iba in the old-world and Clastoptera in the new-world are very closely related. Iba from the Philippine Islands is separated from Parahindoloides from Borneo only by the reduction of one of the lanceolate antennal sensillae (Fig. 24E), and by minor features commonly characteristic of closely allied species (e.g., Tremapterus and Sepullia ), including distinctness of carinae, depth of tegminal pits and size of scutellum ( Maa 1962). Parahindoloides was previously assigned to the Machaerotidae , but this is incorrect ( Maa 1963).

Males are known only from a new species, described below. Those of the previously described species are missing. One male each of the two species in the BPBM were reported by Maa (1962) but their characters were not described or illustrated, and no specimen was found when the collection was visited in 2002 nor when they were again sought by the curator in 2011.
