Bílý, Svatopluk, 2017, A new species-group of the genus Anthaxia (Haplanthaxia) from south-eastern Asia, with descriptions of two new species (Coleoptera: Buprestidae: Anthaxiini), Acta Entomologica Musei Nationalis Pragae 57 (1), pp. 145-152 : 147

Anthaxia (Haplanthaxia) phobos species-group

The Anthaxia (H.) phobos sp. nov. species-group differs from other currently defined species-groups of Haplanthaxia by the following set of characters:

– rather strongly, regularly convex frons;

– frontoclypeus not separated from frons by depression or transverse groove;

– relatively short antennae reaching posterior third of lateral pronotal margins when laid alongside;

– vertex narrow, 0.9 – 1.0 times as wide as width of eye;

– anterior pronotal margin deeply bisinuate;

– pronotal sculpture homogeneous consisting of small, dense, regular, rounded or slightly polygonal cells with well-developed central grains;

– lateroposterior pronotal depressions usually wide;

– elytra only very weakly wedge-shaped almost subparallel ( Figs. 1–2, 4–5 );

– basal, transverse elytral groove very wide, reaching scutellum;

– only the apex of elytra with very fine, lateral serrations;

– scutellum almost 1.5 times as long as wide;

– legs relatively short, male meso- and metatibiae straight, unmodified;

– third and fourth tarsomeres pale, distinctly widened;

– anal ventrite of both sexes of the same shape, only with very fine lateral serrations; – aedeagus spindle-shaped, apical portion of parameres narrow, apically obliquely truncate, somewhat bent outwards ( Figs 3, 6 );

– median lobe with sparse, fine, dorsolateral serrations.

The species-group can be simply attributed to the subgenus Haplanthaxia due to the general body-shape, morphology of the elytral margins and the form of the elytral epipleura at subhumeral part. The species-group is defined by the complete set of the above mentioned characters since each of them separately can be found also in other species-groups and not only in the subgenus Haplanthaxia .
