Moinodaphnia macleayi King, 1853

Specimen examined. Two specimens were examined and stored in UST-ZRC with reference number 0082 and 0133 collected from Lake Calig and a temporary pool in Asibanglan, Pinukpuk, Kalinga.

Description. The body length ranges in 0.9–1.3 mm. The head is sub-triangular in shape. The large eye fills the tip of the head with an ocellus present below the eye and is located above the origin point of the antennules ( Fig. 21D ). Supraocular depression is not present in Moinodaphnia macleayi . The antennules are long and thin, lack the vertical row of long hairs, and are ornamented only with horizontal rows of short setae. The distal end of the antennule has nine sensory papillae. One segment of the second antennae, the basiopod has two sensory setae which originate from the distal end of the rami ( Fig. 12B ). One of the four swimming seta has been reduced in size for genus Moina but remains its longer size in Moinodapnia. The valves of the carapace joined together in the mid-line of the body axis and have a row of small setae. The postabdomen is similar to the genus Moina containing 10–11 feathered teeth and one long bident tooth on the lateral side with pattern of fine setae in the dorsal margin. ( Fig. 21C ).The claw lacks a pecten but with a row of fine short hairs.

Distribution. Cagayan: Lake Calig; Kalinga: Temporary pool in Asibanglan, Pinukpuk ( Fig. 18 ).

Remarks. Moinodaphnia has a different distribution and habitat from that of Moina . It prefers to be in small temporary ponds, small lakes, swamps and pools. The species lives near the mud or in the weeds where it filters the water surrounding the weeds. It is distributed throughout the humid tropics specifically in Africa, Australia, South America, Caribbean Islands, Philippines and India ( Fernando, 2002).
