Limnobaris albosparsa Reitter, 1910 View in CoL

Limnobaris albosparsa Reitter, 1910: 203. Holotype, sex not determined, Ussuri, Russia (HNHM).

Calyptopygus albosparsus : Zherikhin 1997: 3.


Small size (2.7-3.2 mm) and scattered, squamiform, appressed setae on the elytron make Limnobaris albosparsa a distinctive species around the Eastern Sea (Sea of Japan). The aedeagus is identical to that of the more southern Limnobaris tibialis except for its somewhat wider base (Fig. 10 vs. Yoshihara and Morimoto 1994: 451), and the two species usually have a sharply pointed tooth on the ventral edge of the male protibia (Fig. 5). However, they are allopatric (Fig. 13) and Limnobaris tibialis has erect rather than appressed setae on the elytron. Other small species, like Limnobaris basalis , Limnobaris elliptica and Limnobaris martensi , have a blunt male protibial tooth and lack scattered squamiform setae on the elytron.


The species has been reported from Japan (Honshu), Russia (Khabarovsk and Primorsky krajs) and South Korea ( Reitter 1910, Egorov 1976, Yoshihara and Morimoto 1994, Hong et al. 2000, 2011, Legalov 2009). It may occur also in the Chinese provinces Heilongjiang and Jilin (Fig. 13).


Nojima (in Yoshihara and Morimoto 1994) found specimens on Carex dickinsii Franch. and Savat. in Yoshikawa, Japan. Most known collecting dates fall between the middle of May and the end of June. Three specimens were collected in August and September (ZIN, data below) and indicate that the new generation emerges in the same year and overwinters in the adult stage.
