Material examined. – BHUTAN: 1 male, Phuentsholing , 13 May.2000, coll. S. Thapa ; 1 male (2 Oct.2000), 1 male (16 Oct.2000), Tsirang; 1 male (9 Nov.2004) , 1 male (16 Nov.2004) , Gelephu, Purana Bastey , coll. Maha Prasard & Karma Namgyel ; 2 males (2 Nov.2004), 1 male (23 Nov.2004), Purana Bastey , coll. Karma Namgyel & Maha Prasard. All specimens attracted to cue lure. Specimens in NPPC and QDPI .

Diagnosis. – Face fulvous with a pair of small irregularly oval black spots; scutum dark red-brown without distinct dark patterns, postpronotal lobes yellow except posterodorsal corners fuscous, notopleura yellow, mesopleural stripe narrow equal in width to notopleuron dorsally, lateral and medial postsutural vittae absent, a narrow yellow triangle running along anterior margin of mesonotal suture with base on notopleuron; setae: sc. 2; prsc. absent; ia. 1; p.sa. 1; a.sa. 1; mpl. 1; npl. 2; scp. 4; scutellum yellow except for broad redbrown basal band; legs with fore femora dark red-brown to fuscous, mid femora dark red-brown to fuscous except fulvous on basal 1/4, hind femora dark fuscous, fore and mid tibiae dark red-brown to fuscous, hind tibiae dark fuscous, fore tarsi with all segments dark red-brown, mid and hind tarsi with basal segment fulvous and apical four segments redbrown; wings with cells bc and c fuscous, dense microtrichia over all of cell c and most of cell bc, a broad dark fuscous costal band overlapping R 4+5 for its entire length and sometimes becoming darker at apex, cubital streak indistinct but a broad pale fuscous area generally over cell cup and across wing margin towards cell dm, supernumerary lobe weak; abdominal terga III-V generally dark fuscous to black with a paler band often across posterior margin of tergum III, large orange-brown spots posterocentrally on terga IV and V with the spot on tergum V often expanded anteriorly into a medial longitudinal orange-brown band, oval shining spots on tergum V red-brown to dark fuscous.

Attractant. – Cue lure.

Distribution. – Widespread across the region from southern Asia to southeast Asia (see Drew et al., 1998).

Hosts. – Wild species in the Family Cucurbitaceae (see Drew et al., 1998).

Remarks. – This species has a widespread distribution across southern Asia and southeast Asia and has been regularly misidentified with numerous synonyms being described (see notes above). It has been adequately described and illustrated by Drew et al. (1998) and is best distinguished by the combination of the following characters – red-brown scutum, cells bc and c fuscous, costal band overlapping R 4+5, face fulvous with a pair of black spots, anatergite fuscous, katatergite yellow, postpronotal lobes mostly yellow, mesopleural stripe narrow (slightly wider than notopleuron dorsally). It has minor pest status.
