Distribution. Europe, northern Africa ( Algeria), Middle Asia, Siberia, Far East, China and Japan. Distribution in China: Heilongjiang, Hebei, Tianjin, Ningxia, Gansu, Xinjiang, Jiangsu, Hubei, Sichuan, Guizhou ( Fig. 85 View FIGURE 85 ).

Host plants. Ranunculus L. ( Ranunculaceae ), Carex L. ( Cyperaceae ), Brasenia Schreb. (Cabombaceae) , Potamogeton L. ( Potamogetonaceae ), Myriophyllum L. ( Haloragaceae ), Ruppia L. ( Zosteraceae ), Zostera L. ( Zosteraceae ), Sparganium L. ( Sparganiaceae ) ( Bieńkowski & Orlova-Bieńkowskaja, 2004), Vallisneria L. ( Hydrocharitaceae ), Ottelia Pers. (Hydrocharitaceae) and Hippuris L. ( Hippuridaceae ) (recorded in this paper).

Biology. Macroplea is a fully aquatic genus. They live in lentic or lotic water. Both M. appendiculata and M. mutica live in brackish as well as fresh water ( Borowiec, 1984; Kölsch et al., 2006; Saari, 2007; Mende et al., 2010). According to Mende et al. (2010: 101), immobility (cannot swim or fly) is believed to be a specific feature of M. mutica . However, three specimens of M. japana examined in this study were collected by light trap.

Remarks. Identification of species of Macroplea is difficult, despite the genus being less speciose. Many workers have used external morphology, male genitalia, ecological features, and molecular data to delimit species of this genus ( Freude et al., 1966; Daccordi & Ruffo, 1978; Mohr, 1985; Beenen & Winkelman, 1989; Hayashi & Shiyake, 2001; Kölsch et al., 2006). We have followed many of these workers to enhance the reliability of the key. Species of Macroplea can be separated from those of Neohaemonia Székessy in new world by the following characters: 1) vertex with dense pubescence (with a glabrous patch in Neohaemonia ); 2) pronotum with setae at anterior angles (such setae absent in Neohaemonia ); 3) pronotum with distinct anterior and posterior beads (such beads absent in Neohaemonia ); 4) profemur with a short linearly arranged brush of setae basally on posterior surface (such brush of setae absent in Neohaemonia ); 5) endophallus without pELD (pELD present in Neohaemonia ).
