Disepholcia caerulea Butler, 1889 

Trisuloides caerulea Butler, 1889  , Illustrations of Typical Specimens of Lepidoptera Heterocera  in the Collection of the British Museum 7: 5, 35, pl. 128, fig. 3, (TL: India, Himachal Pradesh, Dharmsala [ST: BMNH, London) = coerulea auct, nec, Butler, 1889; = caerula  auct., nec, Butler, 1889.

Material eamined. 28 specimens from Nepal, Myanmar, Thailand, Vietnam, and China (collections AB, AP, GB, ZFMK, ZSM, NEFU).

Diagnosis. ( Fig. 39View FIGURES 39 – 44). Disepholcia caerulea  has a similar ground plan of forewing coloration and pattern as Trisuloides  ; externally it differs from Trisuloides  by its larger size (wingspan 70–75 mm) and by having blackbrown with blue metallic hindwings, without yellow medial part and terminal band as in Trisuloides  . The male genitalia of D. caerulea  ( Fig. 42View FIGURES 39 – 44) is generally similar to Trisuloides  , but differs by shape of editum, which is more strongly sclerotised than in Trisuloides  , seen as a long, finger-like extension and by the shape of harpe which is strongly sclerotised, finger-like, positioned transversally and slightly arched basally. The aedeagus of D. caerulea  is long, relatively thin, with sclerotised carina; vesica simple, tubular. The female genitalia of D. caerulea  ( Fig. 70View FIGURES 67 – 71) differ by the presence of extremely large, strongly sclerotised antrum which is almost equal to corpus bursae in length, very short ductus bursae and presence of a postvaginal plate with two lateral extensions and small central bifurcate extension.

Distribution and biology. The genus occurs in North India, Nepal, Myanmar, Thailand, Vietnam, Malaysia, Indonesia, South and South-East China, including Taiwan Island.
