Hiatusorus , gen. nov.

Type species. Taharana schonhorsti Nielson 1982: 69

Description. Moderately large, slender to robust species. Length male 6.00-7.20 mm., female 7.50-9.00 mm. General habitus as in Taharana ; aedeagus long, narrow, tubular, with short to long narrow, longitudinal dorsal excavation, often bounded by narrow linear dorsal flange or with longitudinal dorsal row of spicules within distal 1/3 of shaft, patch of subapical to apical teeth on dorsal margin; pygofer often with very long caudodorsal process, rarely with long caudoventral process, glabrous or sparsely setose apically; style with moderately long apophysis; subgenital plate frequently spinate apically, accompanied with sparse microsetae or apex sometimes setose without apical spine.

Etymology. The name is a combination of the Latin root hiatus [= opening or slit] and the arbitrary suffix - orus. The gender is masculine.

Remarks. Hiatusorus belongs to the narrow, tubular aedeagus group and can be distinguished by the longitudinal incurvation on the dorsal margin of the aedeagus, with processes limited to the presence or absence of spicules within distal 1/3 of shaft and small, subapical to apical teeth on the dorsal margin. All species except 3 new species are new combinations originally assigned to the genus Taharana . Twenty species are recognized from India to Malaysia.
