Chaetocnema concinnipennis Baly, 1877: 170 . TL: India. TD: BMNH. Lectotype designated here.

Distribution: China (Hainan, Hongkong, Yunnan), Vietnam, Thailand, Malaysia, Singapore, Indonesia, India, Nepal, Sri Lanka; Palearctic Region: Japan; Australian Region: Australia.

Host plants: Oryza sativa Linn. (Poaceae) ( Kulshreshtha and Mishra, 1970; Scherer, 1969; Nair et al., 1976; Batra, 1969), Lagerstroemia indica (Lythraceae) ( Govindan et al., 1986).

Description: Body length 2.00– 2.80 mm, body width 1.50–1.60 mm. Ratio of elytron length (along suture) to width (maximum): 2.20–2.20. Ratio of pronotum width (at base) to length: 1.40–1.45. Ratio of length of elytron to length of pronotum (along middle): 2.50–2.60. Ratio of width of elytra at base to width of pronotum at base (in middle of humeral calli): 1.20–1.25. Ratio of maximum width of elytra to maximum width of pronotum: 1.30–1.40.

Dorsum coppery. Antennomere 1 partially dark brown, 2–5 completely yellow, 6–11 yellow brown to yellow black, apical ones being darkened. Pro- and mesotibia partially brown. Metatibia yellow brown. Pro- and mesofemora light brown. Metafemora brown.

Head hypognathous. Frontal ridge wide and flat. Frontolateral sulcus absent. Suprafrontal sulcus wide and deep with a pit in middle. Ratio of width of frontal ridge to width of antennal socket: 1.90–2.00. Frons evenly covered with relatively short white setae. Vertex flat, situated on same level as orbit. Vertex densely and evenly covered with punctures.

Base of pronotum without short longitudinal impressions. Deep row of large punctures at base of pronotum absent. Pronotal base evenly convex. Area adjacent to mid basal margin of pronotum covered with punctures. Pronotum without shallow antebasal transverse impression. Lateral margins of pronotum slightly convex, converging forward. Anterolateral prothoracic callosity protruding laterally. Posterolateral prothoracic callosity poorly developed. Diameter of pronotal punctures more than distance between punctures.

Elytra with convex lateral sides. Punctures on elytra as large as those on pronotum. Diameter of pronotal punctures larger than distance between them. Scutellar row of elytral punctures confused, arranged in 3–4 semiregular rows. Second to 11th row of punctures extremely closely placed. Humeral callus well developed.

First and second male protarsomeres, length to length ratio: 1.20–1.20. Large lateral denticle on metatibia obtuse. Metatibial serration proximal to large lateral denticle present, obtuse. First male metatarsomere, length to width ratio: 1.20–1.30. First male protarsomere, maximum width to width at base ratio: 1.50–1.60.

In ventral view, aedeagus parallel-sided. Apex of aedeagus in ventral view narrowing abruptly. Ventral surface of apical fourth of aedeagus deeply concave, ventral longitudinal groove of aedeagus well developed, deep, narrowed near basal opening. Apical denticle of aedeagus absent or extremely weak. Minute transverse wrinkles on ventral side of aedeagus well developed. Aedeagus in lateral view evenly and strongly curved. Maximum curvature of aedeagus in lateral view situated medially.

Spermathecal pump much shorter than receptacle. Apex of spermathecal pump flattened. Spermathecal receptacle slightly sinuated. Maximum width of receptacle situated towards middle. Receptacle basally about as wide as apically. Vaginal palpus narrowing from base till middle, thence slightly widening towards apex. Anterior sclerotization of vaginal palpus slightly widening anteriorly. Anterior end of anterior sclerotization broadly rounded. Posterior sclerotization longer than wide. Posterior sclerotization about as wide as anterior.

Remarks: Punctation of dorsum in C. malayana and C. concinnipennis are extremely alike. However, they can be distinguished from each other by the structure of aedeagus. Moreover, in C. concinnipennis , punctures on dorsum are large and extremely closely placed, but in C. birmanica , punctures are smaller and the interspaces are wider.

This species is also close to C. bretinghami , from which it can be distinguished by the closely paced elytral punctures.
