Type material. Holotype: female ( SNHCD), “Pannay Capiz Jamindan coll. W . Schultze \ ♀ \ Callilanguria humeridens HK 1939 Typus \ Museum fur Tierkunde Dresden ( MTD)” . Paratypes: 1 female and 2 males ( SNHCD), with the same data as the holotype .

Diagnosis. This new species resembles C. luzonica by the body size and color but can be distinguished easily by having a protrusion on each elytral humerus in both sexes.

Description. Body length: 20.1–25.3 mm. Head black, pronotum red, legs black, and elytra dark green with metallic luster. Head large, finely punctured; eyes finely faceted; club composed of the last four antennomeres. Clypeus much broader than long. The left mandible of the female longer than the right, acute at apex. In the male, mandibles large but symmetric. Pronotum longer than broad, finely punctured; from dorsal view, lateral pronotal carina invisible at middle; basal margin of pronotum black; basal fovea of pronotum distinct, slightly extended; punctation near the base of pronotum a little coarser than that in the middle. Elytra long, tapering from base to apex; with a distinct tubercle near each elytral shoulder; apex of elytra truncated, with small denticles; sutural and outer angles acute, a little produced.

Etymology. This species is named after Dr. Karl M. Heller due to his contribution to the genus Callilanguria .

Distribution. Philippines: Jamindan.

Remarks. The holotype has a red label with a handwritten name “ Callilanguria humeridens ” by Karl M. Heller, but we could not find it in the Zoological Record nor in any publication. Therefore, we are treating it as an unpublished manuscript name. There are four specimens deposited in SNHCD, including the holotype and three paratypes. Unfortunately, they are more or less damaged by pests and not amenable to dissection.
