Coelophora saucia (Mulsant)

( Figs 73 , 74 )

Lemnia saucia Mulsant, 1850: 380 (Lectotype, UCCC; Type locality: Nepal).— Gordon 1987: 18; Ren et al. 2009: 208; Yu 2010: 73.

Coelophora saucia: Poorani 2002a: 329 .

Coelophora swinhoeii Crotch, 1874: 149 (Lectotype, UCCC).—Synonymized by Iablokoff-Khnzorian 1982: 249; Gordon 1987: 18 (lectotype designation).

Lemnia melanota Mulsant, 1850: 381 (Lectotype female, HEC, OMNH; Type locality: India).—Synonymized and lectotype designated by Booth & Pope 1989: 359.

Diagnosis. Length: 5.80–6.80 mm; width: 4.50–6.00 mm. Form ( Fig. 73a ) circular, dorsum strongly convex and glabrous. Head black. Pronotum black except lateral one-third areas white in live specimens and yellowish in dead specimens, occasionally medially paler with only a posterior transverse black macula. Elytra shiny black, with two large, transverse blood red maculae in middle ( Fig. 74c, d ), sometimes elytra only partially black with anterior and anterolateral areas reddish, with discal reddish spots reduced in size ( Fig. 74e, f ) or almost completely black. Abdominal postcoxal line ( Fig. 73b ) incomplete; ventrite 5 posteriorly broadly emarginate and ventrite 6 slightly more deeply but narrowly emarginate in male ( Fig. 73b ), medially produced and arcuate, respectively, in female ( Fig. 73c ). Male genitalia ( Fig. 73d–g ) and spermatheca ( Fig. 73h ) as illustrated.

This species is similar in general appearance and coloration to C. biplagiata , from which it can be differentiated by the pronotal marking which extends along the lateral margin up to the middle and the genitalia.

Immature stages. Larva ( Fig. 74a, b ) as illustrated.

Distribution. India: Widely distributed (Arunachal Pradesh, Assam, Karnataka, Kerala, Manipur, Meghalaya, Nagaland, Sikkim, Tamil Nadu, Tripura, West Bengal); Nepal; Myanmar; Thailand; China; The Philippines; Korea; Japan.

Prey / associated habitat. Aphidophagous on several commonly found aphids including Aphis gossypii , A. craccivora , and A. fabae (label data). Associated with whiteflies on coconut (label data).

Devi (1989) recorded it as a predator of Aphis kurosawai , Cavariella salicicola , Ceratovacuna lanigera , Cervaphis rappardi indica , Lipaphis pseudobrassicae (as L. erysimi ), and Toxoptera citricida (Aphididae) in association with various host plants in northeastern India ( Solanum sp. , Salix sp. , Cucumis sativus , Vicia faba , Ageratum conyzoides , Brassica napus , Colocasia antiquorum , Gynura angulosa , Mangifera indica , Saccharum officinalis , Artemisia vulgaris , and Cajanus cajan ).

Notes. As mentioned earlier, references to C. biplagiata from India most probably apply to C. saucia , as it is more commonly distributed, particularly in northeastern states. Illustrations of the habitus, life stages and the genitalia are given by Ren et al. (2009) and Yu (2010).
