Location of Types. – Holotype ( T. 152257) and 5 paratypes ( T. 152258 – T. 152262) in QM; 10 paratypes in BMNH; 10 paratypes in ANIC; 41 paratypes in QDPI.

Diagnosis. – A medium sized species; face fulvous with a pair of medium sized oval dark fuscous to black spots; postpronotal lobe and notopleuron yellow; scutum black; two lateral postsutural vittae present; medial postsutural vitta absent; mesopleural stripe reaching almost to anterior npl. seta dorsally; scutellum yellow; wing with a narrow fuscous costal band confluent with R 2+3, broad fuscous cubital streak, cells bc and c with a pale fuscous tint, microtrichia in outer 1 / 2 of cell c; all abdominal terga bright orange-brown with fuscous to dark fuscous oval shining spots on tergum V.

Description. – Female.

Head. – Vertical length 1.7 mm. Frons length 1.6 times breadth; fulvous except red-brown anterocentrally, dark fuscous around orbital setae and dark fuscous to black on anteromedial hump; latter with a large number of small dark hairs; orbital setae black: 1 s.or.; 2 i.or.; lunule red-brown. Face fulvous with a pair of medium sized oval dark fuscous to black spots; length 0.49 mm. Genae red-brown, large dark fuscous subocular spot; dark seta present. Occipital row redbrown, fulvous along eye margins, 4–5 dark setae present. Antennae with segments 1 and 2 red-brown, segment 3 redbrown with dark fuscous on apex and outer surface; length of segments: 0.17 mm, 0.29 mm, 0.84 mm ..

Thorax. – Scutum black with red-brown below and behind lateral postsutural vitta, around mesonotal suture, between notopleuron and postpronotal lobe, inside postpronotal lobe and along anterior margin. Pleural area red-brown except pale fuscous along anterior margin of mesopleural stripe. Yellow markings as follows: postpronotal lobe; notopleuron; mesopleural stripe of medium width reaching almost to anterior npl. seta dorsally, continuing to katepisternum as a transverse spot, anterior margin straight; anatergite (posterior apex red-brown); anterior ¾ katatergite (remainder redbrown); two broad parallel sided lateral postsutural vittae reaching to ia. setae. Postnotum red-brown. Scutellum yellow except for a narrow black basal band. Setae: sc. 2; prsc. 2; ia. 1; p.sa. 1; a.sa. 1; mpl. 1; npl. 2; scp. 4.

Legs. – All segments fulvous except apical fore segments of all tarsi fuscous and hind tibiae pale fuscous; mid tibiae each with an apical black spur.

Wings. – Length 6.0 mm; cells bc and c with a pale fulvous tint; microtrichia in outer one half of cell c only; remainder of wings colourless except fuscous cell sc, narrow fuscous costal band confluent with R 2+3 and remaining of uniform width but very narrow till apex of wing, broad fuscous cubital streak; no dense aggregation of microtrichia around A 1 +CuA 2; supernumerary lobe weak.

Abdomen. – Oval; terga free; no pecten on tergum III. Tergum I and sterna I and II wider than long. All terga bright orange-brown except fuscous to dark fuscous oval shining spots on tergum V. Basal segment of ovipositor dark fuscous, dorsoventrally flattened and tapering posteriorly in dorsal view; ratio of length of oviscape to length of tergum V, 0.8:1; apex of aculeus needle-shaped.

Male. – As for female except dense aggregation of microtrichia around A 1 +CuA 2; supernumerary lobe of medium development; pecten present on abdominal tergum III.

Attractant. – Cue lure.

Distribution. – Morobe Province, Papua New Guinea.

Hosts. – This species has been reared from the genus Uvaria (family Annonaceae ).

Etymology. – The name uvariae refers to the plant genus Uvaria , the endemic rainforest host plant.

Remarks. – Bactrocera uvariae new species possesses the typical musae complex characters of black scutellum, orange-brown abdominal terga and wings with a narrow costal band. It is similar to some specimens of B. bancroftii and B. parabancroftii new species in having a pale tint in cells bc and c, and entirely yellow scutellum and the costal band just overlapping R 2+3 but is unique in having fuscous to dark fuscous shining spots on abdominal tergum V and a dark fuscous basal segment of the ovipositor.
