Camptocercus cf. uncinatus Smirnov, 1971

Specimen examined. One parthenogenic female (UST-ZRC 0139-Dam in Binag, Cagayan).

Description. First described by Smirnov in 1971, it has a worldwide distribution and is almost exclusively littoral as most chydorids are. It has an oval body with several feathered setae in its ventral margin. It has a very small ocellus situated near its rostrum. It has long antennules almost reaching the apex of the rostrum. Its labrum has an irregular convex anterior margin and a few spines and setules on its ventral margin. It has a very narrow distinct post abdomen with 14–16 anal denticles. A single specimen was observed in a local reservoir in Cagayan province ( Fig. 15).

Distribution. Cagayan: A dam in the town of Binag ( Fig. 7 ).

Remarks. A widely distributed species, found in Romania, southwest Siberia, Israel, Iraq, Ethiopia, Egypt, Mexico, and Guatemala. Common in littoral zones of lakes and small streams with thick macrophyte vegetation.
