Taharana Nielson 1982

Type-species. Coelidia sparsa Stål 1854: 254

Description. The genus Taharana is delimited to species possessing a long, narrow, tubular aedeagal shaft which is glabrous except for a longitudinal patch of very fine teeth on the dorsoapical margin. In lateral view, the apex is abruptly curved dorsally at an angle about 45° whereas in related genera the apex is not so curved. The style is very small with a short, digitate apophysis. The pygofer caudodorsal and caudoventral processes vary in configuration. Thirty one species, including 21 new species comprise the genus which is widespread, primarily in the Oriental region.

Intraspecific variation. Variation in specific features of the male genitalia is often recognized among large population of a single species. Coelidiine species, until recently, were rarely collected in large numbers. Flight traps have produced numerous specimens of individual species, known and unknown. Among exemplars, variation is often recognized which may represent several species depending on interpretation of the data. However, a case presented herein is held in abeyance because several forms evident in populations of Taharana serrata Nielson were too close to call. Nine different morphological variations of the caudoventral and caudodorsal processes of the pygofer were recognized in a population of 68 males representing 9 different locations in Thailand. These features are among several that separate several Taharana species ( Table 2).
