Treatment

Macroplea japana ( Jacoby, 1885) .

( Figs 52 View FIGURES 50 – 53 , 54–56 View FIGURES 54 – 59 , 60, 64 View FIGURES 60 – 67 , 68 View FIGURES 68 – 71 , 72–75 View FIGURES 72 – 75 )

Specimens examined. Total 40 specimens: 1 specimen, “Jiangsu, Wuxi, 1951. III.30, Kailing Xia coll.”; 1 specimen, same locality with dating “1951. IX.10 ”; 5 specimens, same locality with dating “1951. XII.7 ”; 6 specimens, same locality with dating “1952. II.4 ”; 24 specimens, same locality with dating “1952. III.20 ”; 2 specimens, “Hebei, Tanghai, 2000.V–VI, by light trap”; 1 male, “Department of Plant Protection, Beijing Agricultural University. Logosun Mountain, Wuchang Town, by light trap. Ruihua Jin coll., 1959. VIII.28 ”.

Distribution. China (Heilongjiang, Hebei, Jiangsu, Hubei), Japan, East Siberia.

Host plant. Unknown.

Biology. The two adults of M. japana from Hebei and one adult from Hubei were collected by light trap, indicating possibility of flight in this species. Light trap records were also found for Neohaemonia species ( Askevold, 1988: 373).

Remarks. Kölsch et al. (2006) recorded M. japana in Heilongjiang, China.

M. japana was treated as a subspecies of M. mutica by workers like Dubieshko (1973) and Kimoto & Takizawa (1994). However, Hayashi & Shiyake (2001) revived its species status after studying the holotype.

In 2006, Medvedev described M. skomorokhovi from Primorskii Territory (Russian Far East). Based on the original description, it differs from M. japana in having round elytral apical sutural angle (see Medvedev, 2006: Fig. 5 View FIGURES 5 – 20 ) (angulate or protruding in M. japana ). However, in a recent personal communication, Dr. Medvedev has informed us that his illustration is not accurate: the sutural angle of M. skomorokhovi is, in fact, angulate. After comparing the types, Dr. Medvedev has opined that M. skomorokhovi is a junior synonym of M. japana , and he will correct the error through a publication later.
