Creberulidia Nielson, 2015: 15

Type-species: Calodia paucita Nielson, 1982: 186 , by original designation.

Description. Moderate sized to large robust species. Length of male 6.00– 10.50 mm. Color relatively dark, mostly fuscous. Head narrower than pronotum. Crown produced beyond anterior margin of eyes. Ocelli small, located near anterior margin of crown; eyes hemispherical, occupying about 2/3 of entire dorsal area of head. Face with frontoclypeus narrow and elongated, surface finely granulose, without median longitudinal carina, lateral margins convex; clypellus long, slightly tumid longitudinally, with apex expanded laterally. Pronotum with tubercular protrusions, median length approximately equal to median length of crown; scutoscutellar sulcus prominent, median length of mesonotum greater than median length of pronotum. Forewings longer than abdomen, with distinct wing veins, 3 ante-apical cells, outer one closed, and 5 apical cells, appendix well developed.

Male genitalia. Aedeagus long to moderately long, narrow, tubular, shaft never inflated or constricted, processes range from few to numerous, very short to moderately long, often setose, sometimes spinose, rarely toothed, rarely in combination, in dorsal view processes often subapical in rows on each lateral margin of shaft, projecting laterally or short to long row on one side of shaft, rare near middle of shaft; pygofer glabrous, usually sparsely setose; pygofer without caudodorsal process, often with small lobe, rarely with caudoventral process, glabrous or sparsely setose; style simple, often with short apophysis; subgenital plate often with apical spine, often in combination with sparse microsetae or not, rarely glabrous.

Remarks. Creberulidia is similar to other Oriental genera of Coelidiini possessing a long, narrow aedeagus but is distinguished from them by the presence of several to numerous processes on the aedeagal shaft. The genus is widely distributed throughout the Oriental region from India eastward across Asia to Japan, the Philippines, and Indonesia.
