Records from Korea : Gyeongsangbuk Province – “ Woolastookia spatulata “ Kim and Chung (1996) , “ W. concava “ Kim and Chung (1996) ; Gangwon Province – “ W. concava “ Kim and Chung (1996) . Remarks : Kim and Chung (1996) described W. concava from the type locality of W. spatulata Kim & Chung, 1996 , a species synonymized by Semenchenko (2010) with W. elongata . They stated that W. concava differs in the ventrally concave shape of IV­L­6. However, as mentioned by Semenchenko (2010) this character may not be suitable for species discrimination, and W. concava should be considered as a further junior synonym of W. elongata . She showed that, if the IV­L is placed in lightly lateral position, its tarsus seems to be narrower and concave ventrally (see Fig. 7C ). Habitat : Rhitrobiont. Distribution : Korea , Far East of Russia .
