9. Phaenochilus ruficollis Weise 1885

Chilocorus ruficollis Weise 1885: 230–231 (original description).

Phaenochilus ruficollis (Weise) : 1895: 136.

Chilocorus celebensis Korschefsky, 1934: 108 (original description); 1938: 40 (synonymy). Type material: C. ruficollis , 2 syntypes, sex unknown (MNHB). Type locality: “ Celebes: Minahassa.” C. celebensis , holotype, sex unknown (MNHB); paratype, female (USNM) (examined). Type locality: “Ahua–Bach, S.O. Celebes.”

Remarks: This melanic species differs from P. mikado and P. flaviceps in the larger body size (TL=4.2–5.0 mm) and the pronotal coloration which is entirely reddish ferrugineus ( Fig. 6). The male genitalia are unknown.

Recuenco-Adorada (2008) included P. celebensis in a paper on Philippine Chilocorini , but apparently misidentified the species. In this work, the redescription and habitus illustration of P. ruficollis were based on specimens from Luzon and Mindanao measuring 2.59–2.72 mm, with an ocherous colored head, pronotum, and elytron. These characteristics, along with the broadly explanate elytral margin shown in the habitus illustration, and the exact shape of some of the other morphological details given, suggest slightly small individuals of P. metasternalis .
