Homalotylus albifrons ( Ishii, 1925)

Anisotylus albifrons Ishii, 1925: 28 .

Homalotylus albifrons (Ishii) : TRJAPITZIN (1989): 361 (new combination).

Type material examined. LECTOTYPE: J (here designated), (No. 5), Nagasaki, ex Scymnus sp. feeding on Pseudococcus sp. on Citrus , 7.ix.1922, T. Ishii lgt. ( NIAES).

Additional material examined. 1 ♀, Matsuyama, 22.ix.1959, ex Pseudoscymnus hareja, T. Tachikawa lgt. & det. (labelled as allotype); 1 ♀ (on slide), 27.ix.1959, ex P. hareja, T. Tachikawa lgt. & det. ( ELKU) .

Distribution. Japan: Kyushu, Shikoku ( TACHIKAWA 1963a). Endemic.

Comments. The lectotype is missing its head and the overall body colouration has faded to orange-yellow probably due to storage in alcohol or similar medium in a glass tube. We have mounted the remains of the lectotype on a card. Examination of the non-type material in Tachikawa’s collection shows that the head is mostly brown, but yellow between the toruli and anterior ocellus. F 1 is dark brown with the remaining funicle segments white, the tegula is brown in the apical half with the basal half white and the mid femur is dusky-yellow. The colour of the head, tegula and mid femur is not included in Ishii’s original description of the species.
