Anthaxia (Haplanthaxia) mindanaoensis Fisher, 1922 , comb. nov.

( Figs. 3, 6 , 11 )

Anthaxia mindanaoensis Fisher, 1922:13 . Type locality: Philippines, eastern Mindanao island, Davao, 7º04′N 125º36′E.

Anthaxia mindanaoensis: OBENBERGER (1930) : 547 (catalogue).

Anthaxia (Anthaxia) mindanaoensis: BÍLÝ (1990) :138 (taxonomy, key, A. weyersi species-group); NOVAK & BÍLÝ (1991): 4 (taxonomy, key); BÍLÝ (1997): 29, 92 (catalogue); BELLAMY (2008): 1429 (catalogue).

Type specimen studied. HOLOTYPE (by monotypy): ♀ ( USNM, type no. USNM 24671 ), PHILIPPINES: EASTERN MINDANAO: “ Davao [7º04′N 125º36′E] / Mindanao / [C. F.] Baker [leg.] [p] // 8337 [h] // Type No. / 24671 / U.S.N.M. [p+h, red label] // Anthaxia / mindanaoensis / Fisher [h]”.

Further specimens studied. PHILIPPINES: NORTHWESTERN MINDORO: Abra de Ilog [13º26′N 120º44′E], W. Schultze leg. (3 ♂♂ 2 ♀♀, NMPC; 1 ♂ 2 ♀♀, SMTD) ; Mt. Calavite [13º29′N 120º23′E], W. Schultze leg. (4 ♂♂ 3 ♀♀, SMTD).

Diagnosis. Very small (3.0- 3.7 mm), suboval, black-bronze species ( Fig. 3 ); elytra suboval with small, blue-green postscutellar stripe, frons very slightly convex, lateroposterior pronotal depressions very often with golden green tinge; parameres strongly constricted at apical third, median lobe sharply pointed ( Fig. 11 ). Sexual dimorphism nearly absent: the female differs from the male only by somewhat stouter body and by nearly parallel anterior two thirds of elytra which nearly completely cover the abdomen (elytra of male more sphenoidal, not completely covering abdomen) – see Figs. 3, 6 .

Differential diagnosis. Anthaxia (Haplanthaxia) mindanaoensis is similar to A. (Anthaxia) weyersi ( Indonesia: Sumatra, Java) which differs from A. (H.) mindanaoensis only weakly by the characters distinguishing both subgenera (well-expressed only in males), by the elytral epipleura reaching only the apical, rounded part of the elytra, by the lighter colouration, by the more sphenoidal body and by the form of the median lobe, which is slender and more pointed in A. (H.) mindanaoensis .

Remarks. In the female holotype (see Fig. 3 ) the elytra completely cover the abdomen, which was the main reason for attributing this species to the A. (A.) weyersi species-group ( BÍLÝ 1990). As a matter of fact, all members of this species-group are very close to the subgenus Haplanthaxia .

Distribution. Philippines (Mindanao, Mindoro). New for Mindoro.
