Synonyms
Chilocorus maculatus Slipinski and Giorgi, 2006: 270.
Diagnosis
The piceous pronotum with only anterior angles yellowish, the 4 yellow well defined elytral maculae and the piceous thoracic sternites distinguish this species from the other Australian Chilocorus.
Description
Length 3.7-3.9 mm. Head entirely yellowish. Pronotum blackish with anterior angles yellowish; elytra predominantly piceous, each elytron with 2 large, somewhat rounded yellowish maculae, an antero-lateral one touching the lateral and anterior margin; a posterior one on apical fourth touching the lateral margin and suture. Head flat between eyes, polished between punctures; punctation somewhat obsolete, present only in the clypeal lateral extension. Eyes dorsally separated by approximately the width of an eye; inner ocular margin strongly diverging apically. Clypeus not projecting forward; slightly emarginate. Antennomere 8 long, about as long as 6th and 7th combined. Terminal maxillary palpomere with sides nearly parallel; terminal labial palpomere slender, about 3 times longer than basal width, about as long as preceding segment. Pronotal surface polished between punctures; punctation smaller than eye facets, shallow and sparse, approximately 2 diameters apart, obsolete on anterior angles; lateral border rounded; bordering line absent at base; prosternum short, slightly shorter than prosternal process widest width; hypomeral foveae absent. Elytral surface polished between punctures; punctation stronger in than on pronotum, slightly deeper and denser, about as large as to larger than eye facets, much larger at lateral margin, forming a irregular row across margin; epipleura foveae conspicuous. Abdomen with ventrite 6 very short, rounded at apex; surface of ventrite 1 polished between postcoxal lines.
Male
Tegmen relatively long, about 3/4 the abdomen length; penis guide symmetrical, slightly shorter than parameres; parameres densely setose at apex, the setae short; strut about as long as tegmen.
Female
Abdominal ventrites 5th and 6th broadly rounded.
