Dimension : Female, RV, n = 3, length 0.749 –0.915 mm , height 0.402 –0.554 mm ; LV, n = 4, length 0.723 –0.869 mm , height 0.426 –0.519 mm . Description : In dorsal view, RV overlapping LV anteriorly, ventrally and dorsally ( Fig. 17A ). In lateral view, carapace sub-elliptical. Surface of valves mostly smooth, but LV with area of small pits near anterior margin ( Fig. 17B ). Greatest height at mid-length. Calcified inner lamella anteriorly wide. Marginal denticles present along anterior and postero-ventral margins of LV ( Fig. 17D ). Marginal sockets present on anterior and postero-ventral part of RV ( Fig. 17C ). Natatory setae on A2 long, exceeding tips of terminal claws. Terminal segment of Mx palp spatulalike, and one tooth-bristle on third endite smooth, other with denticles ( Fig. 18A ). L6 five-segmented, only d1 seta present on basal segment ( Fig. 18C ). Claw Gp on UR approximately 3/4 length of claw Ga ; Seta Sp slightly shorter than claw Gp ; Seta Sa shorter than 1/2 length of claw Ga ( Fig. 18B ). UR attachment simple, and ventral branch well-developed. Distribution : This species has been found in Malaysia , the Philippines ( Victor & Fernando 1981d ), India ( Victor & Fernando 1979b ; Patil & Talmale 2005 ; Karuthapandi et al. 2014 ) and provinces in China : Taiwan ( Klie 1938b ) and Sichuan ( Huang 1986 ).
