Chilocorus mikado Lewis 1896: 32 (original description); Kurisaki 1921: 39; Mader 1955: 738; Kamiya 1959: 101 (male genitalia figured); Kamiya 1966: 77 (key to scale and mite feeding Coccinellidae of Japan and the Ryukyus); Sasaji 1971:

225, pl. 10 (dorsal habitus, male genitalia figured); Osaka Natural History Museum 2012 (online key to Coccinellidae of

Osaka Prefecture). Chilocorus micado: Korschefsky 1932: 240 (catalogue) (typo). Phaenochilus mikado: Sasaji 2005: 64 (morphological details figured); Shiyake 2009: 14–36 (key to Coccinellidae of Japan). Chilocorus nigritus: Lewis 1873: 56 , not Fabricius 1798, nomen nudum; Crotch 1874: 184 (in part).

Type material: Unique syntype, sex unknown ( BMNH). Type locality: “ Nagasaki.”

Remarks: This melanic species can be distinguished from P. flaviceps by the male genitalia which have a more blunt triangular projection at the apex of the basal lobe and digitiform parameres ( Fig. 8). It differs from P. ruficollis in having the median part of the pronotum black or deep piceous ( Fig. 2) as opposed to reddish ( Fig. 6).

According to the Japanese Red Data Retrieval System (2012), the species is known from Nagasaki Prefecture, Island of Kyushu , and Nara and Kyoto Prefectures, Island of Honshu in Japan .

This species was originally confused with Chilocorus nigritus F. by Crotch (1874) who applied that name to a male specimen from Nagasaki in the collection of G. Lewis. Lewis (1873) published Crotch’s determination one year prior, listing it in a note as “ Chilocorus nigritus, Crotch (sp. n.).” Subsequently ( Lewis 1896) published the full description under the new name Chilocorus mikado Lewis.
