( Figures 1–8 ) urn:lsid:zoobank.org:act: 0709E585-C164-44A0-8CD7-BBB6F25F670E Description: Male A medium-sized fly, (total body length – 6.5 mm ), reddish-brown to black species. Head ( Fig. 1 ): Face 1.44 mm high and 1.88 mm wide, frons 0.73 mm high and 0.58 mm wide, face entirely fulvous with the oral margin 0.56 mm high and 0.93 mm wide with elongate facial oval spots of 0.34 mm high and 0.16 mm wide, frons with three frontal setae and two orbital setae, bases of all setae black, ocellar triangle black, ocellus fuscous, outer vertical seta and medial vertical seta well developed; prominent fuscous markings on gena connected to eye margin, occiput black except posterior margin of eye and vertex, postocular setae thin, lunule fuscous; antennal segments dark fuscous on outer side, arista not plumose, combined length of antennal segments viz., scape ( 0.35 mm ), pedicel ( 0.32 mm ) and flagellomere ( 0.83 mm ) almost equal to the vertical length ( 1.44 mm ) of face. Thorax ( Figs 2, 3 ): Scutum reddish brown to black ( 2.36 mm high and 2.05 mm wide) with lanceolate markings; lateral postsutural vitta narrow ( 0.12 mm ) obscured beyond postsutural supra-alar seta, ending at or before intra-alar setae and medial postsutural vittae absent. Yellow markings as follows, notopleuron, postpronotal lobe, narrow mesopleural (anepisternal) stripe ( 0.81mm high and 0.36 mm wide), almost equal to notopleuron, continued as yellow transverse spot on katepisternum, 0.5 of katatergite and anatergite. Scutellum yellow ( 0.48 mm long, 1.1 mm wide) with a narrow ( 0.05 mm ) black basal band, subscutellum black with 0.64 mm high and 1.2 mm wide and with thin medial reddish-brown line. Chaetotaxy: 2 scapular setae; 1 anterior notopleural seta; 1 posterior notopleural seta; 1 mesopleural seta; 1 post sutural supra-alar seta; 1 prescutellar setae; 1 post-alar seta; 1 intra-alar seta; 1 apical scutellar setae. Legs ( Fig. 3 ): Coxa, trochanter, tibia of fore and hind legs, 0.4 of tibia of mid legs, tarsus and pretarsus of mid legs are fuscous; remainder fulvous. Wing ( Fig. 5 ): ( 5.12 mm ) predominantly hyaline, cell bc and c colourless, narrow costal band from cell sc to wing apex confluent with vein R 2+3 , extension of cell cup longer than cup, anal streak present. Abdomen ( Fig. 4 ): Abdomen oval ( 3.23 mm long; 2.41 mm wide) predominantly red-brown to black except fulvous band on tergites II transversely, pecten on tergite III and a brown medial patch gradually expanding over tergites III-V, with dense white hair over the medial region, and two large spots on tergite V, sternite I, II and V are fuscous and II and III are fulvous, sternite V of male with a deep posterior emargination. Male genitalia ( Figs 6, 7, 8 , 41 , 45 , 49 ): Epandrium and surstyli inverted U-shaped in outline (posterior view), strongly sclerotised, epandrium quadrate, as long as wide ( 0.28 mm high; 0.26 mm wide) equal to length of lateral surstylus ( 0.27 mm ), lateral surstylus broad ( 0.1 mm ), posterior lobe of lateral surstylus, pointed, curved back ( 0.11 mm ), not longer than anterior lobe ( 0.25 mm ); proctiger membraneous ( 0.06 mm ), dome shaped and smaller than epandrium, medial surstylus as long as lateral surstylus tapering towards apex with a pair of thick prensisetae. Phallus elongate ( 2.63 mm ) with well-developed glans ( 0.43 mm ) ( Figs 8 , 49 ); 0.75 of glans sclerotised with unpatterned praeputium; subapical lobe and basal lobe present. Attractant: Methyl eugenol. Host plant: Not known. Material examined: Holotype , 1♂ , INDIA , Karnataka , Chikkamagaluru , Ettinabhuja , 14.x.2023 , Abhishek , V . (NIM). Etymology: This species is named after the type locality of the species and is a noun in apposition (Ettinabhuja). Diagnosis: Bactrocera ( Bactrocera ) ettinabhuja sp. nov. is similar to Bactrocera ( Bactrocera ) paraosbeckiae Drew in possessing reddish brown scutum ( Figs 2 , 18 ) and elongate ( 0.27 mm ) lateral surstylus ( Figs 6 , 22 , 41, 43 ) but can be differentiated by black subscutellum ( Fig. 53 ); lateral vitta narrow ( 0.12 mm ) obscured beyond postsutural supra-alar seta, ending at or before intra-alar setae ( Fig. 2 ); narrow costal band confluent with R 2+3 ( Fig. 5 ); ceromata reddish brown ( 0.33 mm high, 0.62 mm wide) ( Figs 4 , 57 ); abdominal sternites I, II and V fuscous, II and III fulvous and males are attracted to Methyl eugenol. In contrast, B. paraosbeckiae possess black subscutellum with medial brown patch posteriorly ( Fig. 56 ); lateral vitta tapering posteriorly ( 0.13 mm ) ending at intra-alar seta ( Fig. 18 ); costal band overlapping vein R 2+3 ( Fig. 21 ); ceromata predominantly fuscous ( 0.37 mm high, 0.56 mm wide) ( Figs 20 , 59 ); abdominal sternites I, III, IV and V fuscous, II fulvous and males are attracted to cuelure.
