Cautires regalis ( Kleine, 1929) , comb. n.

Bulenides regalis Kleine, 1929: 227 .

Type material. Ƥ holotype. [ Bangladesh] Chandkhira, Sylhet, J. L. S. ( BMNH).

Differential diagnosis. C. regalis is the only species from the C. obsoletus groups occurring in Bangladesh. The species differs from remaining species from continental Asia in the completely black pronotum. Although other species have often darker bottom of areolae in the pronotal disc, they have always the brightly coloured ridges and margins. The species is known only in a single female and further material is needed for reliable delineation of this species.

Redescription. Body medium sized, slender, dark brown to black, only elytra reddish brown, with brightly coloured dense pubescence. Head small, partly hidden in pronotum, mat, with dense pubescence, eyes small, mandibles light brown, apical palpomere of maxillary palpi pointed, slightly lighter apically, antennae strongly serrate. Pronotum 1.48 times wider at base than length at midline, frontal margin rounded, projected anteriorly, frontal angles obtuse, rounded, lateral margins straight, posterior angles acutely projected backwards. Median areola slender, directly attached to middle of basal margin, connected with frontal margin by ridge forming one third of pronotal length. Scutellum black, deeply emarginate at apex. Elytra parallelsided, with completely developed primary and secondary longitudinal costae in basal half of length, secondary costae vestigial apically. Male unknown.

Measurements. BL 7.90 mm, PL 1.12 mm, PW 1.92 mm, HW 2.20 mm.

Distribution. Bangladesh, Sylhet.
