Diagnosis. Medium sized (5.89̄ 6.02 mm), reddish brown species. Face fulvous with elongate, black spot in each antennal furrow, scutum reddish brown, with broad, yellow lateral postsutural vitta tapering posteriorly and ending at intra-alar seta, medial postsutural vitta lacking, anepisternal stripe reaching midway between anterior notopleural seta and notopleural lobe, continued as small transverse spot on katepisternum, scutellum yellow with narrow, black basal band, mediotergite and subscutellum red-brown. All femora fulvous without fuscous markings, tibia slight fuscous, tarsal segments fulvous. Wing (5.2̄ 5.4 mm) predominantly hyaline, cell bc and c hyaline, narrow costal band from cell sc to wing apex overlapping vein R2+3, expanded slightly towards apex, extension of cell bcu longer than bcu, anal streak present. Abdomen, oval, tergites I+II fulvous with a narrow transverse band on tergite II, tergites IIĪV red-brown except for a narrow transverse band on tergite III and a narrow, medial longitudinal vitta on tergites IIĪV, tergite III with pecten, sternite V of male with a deep posterior emargination.
Male genitalia: Epandrium and surstyli inverted U-shaped (posterior view), epandrium shorter than lateral surstylus, lateral surstylus broad (0.1 mm), posterior lobe of surstylus blunt, curved back, not longer than anterior lobe. Proctiger membraneous, triangular, smaller than epandrium. Medial surstylus longer than lateral surstylus, tapering towards apex with a pair of thick prensisetae. Aedeagus 1.9¯ 2.1 mm long excluding glans (0.38 mm); 0.75 of glans sclerotised with well developed acrophallus, unpatterned praeputium; subapical lobe and basal lobe present.
Material examined. 30♂♂, INDIA, Tripura, Agartala, Attur farm, 10.iii.2016, Sunil Joshi. (NBAIR).
Male parapheromone. Cue lure.
Host plants. Litsea verticillata (Lauraceae) (Liang et al., 1993).
Known distribution. China, Bhutan, Thailand and Northern Veitnam (Drew and Romig, 2013)
Remarks. Bactrocera rubigina is similar to B. blairiae and B. bhutaniae in possessing reddish brown scutum, abdomen and narrow costal band. It can be differentiated from B. blairiae by tapering lateral postsutural vitta and costal band overlapping vein R2+3; from B. bhutaniae by the absence of dark scutal patterns and lateral postsutural vitta tapering posteriorly.
