Diagnosis. TL 18–23 mm, elongate, oblong-oval ( Fig. 17A View Fig ). Head, pronotum and elytra dark green to black, lateral part of pronotum reddish-brown, apex of elytra with reddish-brown spots. Ventral surface black; abdominal ventrites III–IV with a yellow spot on each side ( Fig. 17B View Fig ). Dorsal surface smooth. Prosternal process lanceolate, with distinct lateral bead, surface flat, apex pointed; lateral parts of metaventrite tongue-shaped, slender, not reaching lateral margins; metacoxal lines distinct, well impressed, nearly parallel medially, divergent anteriorly, along metacoxal lines with a row of punctures. Forelegs reddish-brown, midlegs and hindlegs reddish-brown to black; protarsomeres 1–3 of male broadly expanded into a palette, with four rows of adhesive setae on their ventral side; male with a single metatarsal claw; female with two metatarsal claws, posterior claw small and sinuate. Medi- an lobe of aedeagus ʻCʼ- shaped in lateral view, strongly curved, broadest at middle, strongly narrowing in apical fifth, apex rounded ( Fig. 17C View Fig ); broad medially in ventral view, apical fifth slender like a tubular spine, apex rounded ( Fig. 17D View Fig ). Parameres moderately broad, strap-like apically ( Fig. 17E View Fig ).

Habitat. This species inhabits not only ponds, wetlands, abandoned paddy fields and ditches of paddy fields with aquatic plants, but also eutrophic waters near grazing land

( MORI & KITAYAMA 1993). Specimens from Shenzhen (Guangdong) were found in in a lowland marsh ( Figs 18D–E View Fig ) and specimens from Lvchun County (Yunnan) were found in terraced fields ( Fig. 18H View Fig ).
