Ephemeroporus barroisi ( Richard, 1894)

Specimen examined. Six parthenogenic female ( UST-ZRC 0126,0131 - Lake Danao, Camotes Is., Cebu; 0127–0129- Lake Mainit, Agusan Del Norte;0128- Lake Paoay , Ilocos Norte) .

Description. Relocated from the genus Chydorus , this species is easily identified by its serrated labrum with four teeth ( Frey, 1982). Its body is globular to subglobular like other chydorids. It has short blunt rostrum in comparison with C. sphaericus . Its ocellus is large but slightly smaller than the eye. The post abdomen is ciliated along its entire length. It is found only in the tropics. It is relatively well distributed in the Philippines with specimens found from Luzon to Mindanao ( Figs. 9 , 10 ).

Distribution. Ilocos Norte: Lake Paoay; Cagayan: A dam in Binag, Lake Nalbuan, Lake Calig, Camarines Sur: Lake Baao; Cebu: Lake Danao; Negros Oriental: Lake Kabalin-

an: Agusan Del Norte: Lake Mainit ; South Cotabato: Lake Lahit, Lake Siloton ( Fig. 7 )

Remarks. Possibly well distributed in the tropics and sub tropics with specimens reported in Syria, Iran, India, Sri Lanka, Australia, Nicaragua and North America. It is considered as a species complex that can be separated into several species. Fairly common in littoral zones and sometimes present in low numbers in the limnetic and lotic habitats.
