description: Bactrocera (Parazeugodacus) conica David and Ramani, sp. nov.
Description: Medium sized (5.9 mm), black species. Frons fulvous with two frontal setae and single orbital seta, ocellar triangle black, ocellus fuscous, outer vertical seta and medial vertical seta present; occiput fuscous with a row of thin, black postocular setae; face fulvous with elongate, black spot in each antennal furrow, gena fulvous with subocular spot and seta. Scape, pedicel fuscous; first flagellomere dark fuscous; combined length of pedicel and first flagellomere as long as the vertical length of face (Fig. 1A). Scutum (2.07 mm long; 1.67 mm wide) predominantly black without lateral and medial postsutural vitta. Yellow markings as follows; postpronotal lobe, notopleuron, narrow anepisternal stripe (as broad as notopleuron, not continued as a small spot on katepisternum), 0.6 of katatergite and 0.9 of anatergite. Scutellum yellow with a broad, medial black patch and two pairs of scutellar setae; mediotergite and subscutellum black. Chaetotaxy; 2 scapular setae, 1 anterior notopleural seta, 1 notopleural seta, 1 anepisternal seta, 1 postsutural supra-alar seta, 1 post-alar seta, 1 intra-alar seta, 1 prescutellar acrostichal seta and 1 scutellar seta. Legs; coxa, trochanter black, all femora with apical ring like fuscous markings, tibia fuscous, tarsal segments fulvous (Fig. 1B,C). Wing (4.20 mm) predominantly hyaline without costal band, pterostigma dark brown, base of cell br hyaline without microtrichia, extension of cell bcu slightly longer than bcu, anal streak lacking (Fig. 1E). Abdomen (2.07 mm long; 2.09 mm wide) oval, wholly black (dark brown in Fig. 1D after processing in KOH) except two hyaline spots on tergite II (Fig. 1D).
Female genitalia: Oviscape black (0.7 mm); spicules on distal end of eversible membrane (0.96 mm) conical (Fig. 1G), Acuelus (Fig. 1F) needle shaped (0.9 mm), length to width ratio, 5.3, aculeus tip acute without distinct preapical setae (Fig. 1G); black, convoluted, mulberry shaped spermathecae (Fig. 1I).
Material examined: Holotype 1♀, INDIA, Karnataka, Chikmagalur, Mudigere, 03.vii.2012, David, K. J. (deposited at NBAIR)
Etymology: The species is named for its conical-shaped spicules on distal end of eversible membrane.
Remarks: Bactrocera conica is similar to B. bipustulata (Bezzi) in possessing hyaline wing without costal band, scutellum with a black medial patch; but it can be differentiated by the presence of separate black spots on the face (Fig. 1A), scutum without lateral postsutural vitta (Fig. 1B), katepisternum without yellow spot (Fig. 1C), femur not predominantly fuscous, abdomen fully black and conical shaped spicules on distal end of eversible membrane (Fig 1H). In contrast, B. bipustulata possess entirely black face (Fig. 1J), scutum with lateral postsutural vitta extending upto postsutural supra-alar seta (Fig. 1K), femur predominantly fuscous, katepisternum with yellow spot (Fig. 1L), abdomen not wholly black (Fig. 1M) and broad spicules with 3-5 projections (Fig. 1P) on distal end of eversible membrane. Since males were not available for the study, it is retained in the genus Bactrocera.
