Key to the Philippine species of Anthaxia

1. Elytra parallel for anterior two thirds; elytral margins straight, or only slightly emarginate posteriad humeri; abdominal segments completely covered by elytra. .............................. ...................... subgenus Anthaxia Eschscholtz, 1829 (does not occur in the Philippines)

– Elytra more or less sphenoidal, tapering posteriorly; elytral margins distinctly, very often deeply emarginate posteriad humeri; lateral portions of abdominal segments usually not covered by elytra, well-visible in dorsal view (more distinct in males) (subgenus Haplanthaxia Reitter, 1911 ). ....................................................................................................... 2

2. Elytral epipleura reaching only apical rounded part of elytra; head narrower than anterior pronotal margin; median lobe of aedeagus with lateral serration. ................................... 3

– Elytral epipleura reaching middle of apical rounded part of elytra (but not reaching elytral suture); head wider than anterior pronotal margin; median lobe of aedeagus without lateral serration. .......................................................................................................................... 5

3. Frons convex, microsculptured; lateral pronotal margins subparallel, maximum pronotal width at midlength; elytra subparallel at anterior two thirds; anal ventrite of female rounded apically; aedeagus as in Fig. 12 ; 3.6–3.9 mm; Figs. 8, 9 . Luzon, Negros, Sibuyan. .......... ........................................................................................... A. (H.) philippinensis sp. nov.

– Frons flat with feeble medial groove, without microsculpture; lateral pronotal margins rounded, maximum pronotal width at posterior third or at midlength; elytra tapering from humeri to apex; anal ventrite of female notched apically. ............................................... 4

4. Pronotum distinctly wider than elytra, maximum pronotal width at midlength; parameres with fine dorsal denticulation at posterior half, aedeagus as in Fig. 14 ; 4.0 mm; Fig. 1 . Negros. ............................................................................. A. (H.) attenuata Fisher, 1922

– Pronotum as wide as elytra across humeri, maximum pronotal width at posterior third; parameres with dorsal and lateral denticulation at posterior half; aedeagus as in Fig. 13 ; 3.3–5.1 mm; Figs. 2, 4, 5 . Luzon, Mindoro , Palawan, Sibuyan. ........................................ .................................................................................. A. (H.) boettcheri Obenberger, 1928

5. Pronotal and elytral sculpture very fine; frons flat; lateroposterior pronotal depressions and postscutellar portion of suture with very weak green lustre; frons of male black; male meso- and metatibiae not modified; aedeagus as in Fig. 11 ; 3.0– 3.7 mm; Figs. 3, 6 . Mindanao, Mindoro. .................................................................. A. (H.) mindanaoensis Fisher, 1922

– Pronotal and elytral sculpture rough; frons slightly depressed; lateroposterior pronotal depressions and circumscutellar portion of elytra golden green; frons of male golden green; male mesotibiae with deep, inner, preapical emargination ( Fig. 7 ), metatibiae with inner, apical spine ( Fig. 7 ); aedeagus as in Fig. 10 ; 3.6 mm; Fig. 7 . Palawan. ............................ ........................................................................................... A. (H.) palawanensis sp. nov.
