Bactrocera (Parazeugodacus) conica David and Ramani View in CoL , 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 View FIGURE 1 ). 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 View FIGURE 1 ). 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 View FIGURE 1 ). Abdomen (2.07 mm long; 2.09 mm wide) oval, wholly black (dark brown in Fig. 1D View FIGURE 1 after processing in KOH) except two hyaline spots on tergite II ( Fig. 1D View FIGURE 1 ).
Female genitalia: Oviscape black (0.7 mm); spicules on distal end of eversible membrane (0.96 mm) conical ( Fig. 1G View FIGURE 1 ), Acuelus ( Fig. 1F View FIGURE 1 ) needle shaped (0.9 mm), length to width ratio, 5.3, aculeus tip acute without distinct preapical setae ( Fig. 1G View FIGURE 1 ); black, convoluted, mulberry shaped spermathecae ( Fig. 1I View FIGURE 1 ).
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 View FIGURE 1 ), scutum without lateral postsutural vitta ( Fig. 1B View FIGURE 1 ), katepisternum without yellow spot ( Fig. 1C View FIGURE 1 ), femur not predominantly fuscous, abdomen fully black and conical shaped spicules on distal end of eversible membrane ( Fig 1H View FIGURE 1 ). In contrast, B. bipustulata possess entirely black face ( Fig. 1J View FIGURE 1 ), scutum with lateral postsutural vitta extending upto postsutural supra-alar seta ( Fig. 1K View FIGURE 1 ), femur predominantly fuscous, katepisternum with yellow spot ( Fig. 1L View FIGURE 1 ), abdomen not wholly black ( Fig. 1M View FIGURE 1 ) and broad spicules with 3-5 projections ( Fig. 1P View FIGURE 1 ) on distal end of eversible membrane. Since males were not available for the study, it is retained in the genus Bactrocera .
