Head transverse, with a wide base, ratio of its length (from posterior margin of head to anterior margin of clypeus) to maximum width about 23:33. Neck constriction prominent. Eyes large, convex, occupying almost entire lateral side of head; temples almost indistinct, the head has the largest width in the eye area ( Fig. 1 View Figs 1–3 ). Head surface with clearly, rather finely and dense punctation. Diameter of punctures is about 1.5 times smaller than the eye facet. Distances between punctures significantly smaller than their diameter, interspaces smooth, shining ( Fig. 1 View Figs 1–3 ). Antennae long, with lengths of all antennal segments noticeably or significantly longer than their width ( Fig. 1 View Figs 1–3 ).
Pronotum heart-shaped, reaches its greatest width after about 2/3 of the length measured from the base, then narrowed ( Fig. 1 View Figs 1–3 ). Ratio of pronotum length to its maximum width is about 28:36. Surface of pronotum with clearly, rather finely and dense punctation. Diameter of punctures about 1.5 times smaller than the eye facet. Distances between punctures are significantly smaller than their diameter, interspaces smooth, shining ( Fig. 1 View Figs 1–3 ). Base of pronotal disc with distinct horseshoe-shaped depression ( Fig. 1 View Figs 1–3 ); central part of disc with 2 symmetrical distinct weakly developed oval depressions.
Ratio of length of elytra to their combined width about 46:54. Elytra with clearly, rather finely and dense punctation. Diameter of punctures dots is approximately equal to eye facet. Distances between punctures significantly smaller than their diameter, interspaces smooth, shining ( Fig. 1 View Figs 1–3 ).
Abdomen with fine and sparse punctation, shining.
Aedeagus of characteristic structure, with a peculiar form of paramers ( Figs 4–5 View Figs 4–12 ).
Female. Sexual dimorphism is absent, female morphologically similar to male. Spermatheca of characteristic structure ( Fig. 6 View Figs 4–12 ).
COMPARATIVE REMARKS. The species is distinguished by its small size, clear puncturation of the body surface and light coloring of the apex of the elytra. Reliably different in the structure of the aedeagus, especially in the form of parameres ( Figs 4–5 View Figs 4–12 ).
DISTRIBUTION. Philippines ( Fig. 13 View Figs 13–14 ).
ETYMOLOGY. From Latin “coronatus ” (crowned); the name refers to the structure of parameres.
