Diagnosis. Small, navicular species with rather strong sexual dimorphsm (Figs. 4, 5): male slender, nearly triangular, bronze, frons, antennae, anterior tibiae, pro- and mesofemora golden green or blue-green; mesotibiae with very fine, inner, preapical serration, anal ventrite truncate; female much robuster, completely bronze with simple mesotibiae and rounded, medially notched anal ventrite; aedeagus (Fig. 13) slightly spindle-shaped, nearly subcylindrical, dorsal surface and lateral margins of parameres with fine denticulation at posterior half.

Differential diagnosis. See key and the diagnosis of Anthaxia (Haplanthaxia) attenuata .

Remarks. The denticulation of dorsal surface and lateral margins of parameres in Anthaxia (H.) boettcheri and A. (H.) attenuata is quite a unique phenomenon which has not been observed in the genus Anthaxia, yet. The male specimen from Palawan possesses parameres without distinct denticulation but other characters incl. the shape of aedeagus correspond well with A. (H.) boettcheri .

To avoid any confusion in the future, and for the sake of the stability, considering the fact that the number of syntypes of A. (H.) boettcheri is unknown, we hereby designate the wellpreserved male syntype from NMPC as the lectotype (Fig. 2) and the female syntype from SMTD as the paralectotype.

Distribution. Philippines (Luzon, Mindoro, Palawan, Sibuyan). New for Mindoro, Palawan and Sibuyan.
