Bactrocera yoshimotoi

description: New record of Bactrocera (Zeugodacus) yoshimotoi (Hardy) from Himachal Pradesh (Figures 8–9)
Diagnosis: A medium-sized (5.3± 0.063 mm) species (Figure 8) included in the scutellaris group by Drew and Romig (2013) and Hancock and Drew (2018b). It was adequately described by Drew and Romig (2013) except for male postabdominal characters noted below.
Male genitalia: Epandrium and lateral surstylus of similar length; epandrium elongate-oval in posterior view (Figure 9A). Proctiger quadrate, setose and smaller than epandrium. Posterior lobe of surstylus longer than anterior lobe and medial surstylus as long as lateral surstylus. Aedeagus 2.32 mm long with 0.34 mm long glans. Glans with patterned narrow praeputium, covered normally by vesica. Subapical lobe capitate in shape (Figure 9B).
Female genitalia: Aculeus short (0.5 mm) and tapering at both ends. Aculeus tip trilobed with three preapical setae. Eversible membrane 0.88 mm long and oviscapt 1 mm long. Oviscapt black but reddish fulvous at posterior end. Spicules on distal eversible membrane with 3–4 broad projections (Figure 10).
Material examined: 1 ♀ & 17 ♂, Cuelure, INDIA, Himachal Pradesh, Solan, Nauni, 30°51’24”N 77°10’17”. 20.vii.2020, Maneesh. Voucher specimens deposited in High Altitude Regional Centre, Zoological Survey of India, Solan, Himachal Pradesh, India and Department of Entomology, Dr. Yashwant Singh Parmar University of horticulture and Forestry Nauni, Solan, Himachal Pradesh, India.
Male parapheromone: Cue lure.
Host plants: Not recorded but likely to be flowers of Cucurbitaceae.
Remarks: This species is similar in appearance to B. caudata (Fabricius) and B. tau (Walker), both also present in northern India, but can be separated from B. caudata by oval facial spots rather than a transverse black band above the oral margin, from B. tau by the narrow apical expansion of the costal band and from both by the single pair of scutellar setae, the basal pair being absent.
Bactrocera luteicinctuta Ito, described from Nepal (Ito 2011), falls within the range of variation noted for B. yoshimotoi discussed by Drew and Romig (2013) and shows no specific characters to enable separation. Doorenweerd et al. (2018) and Hancock and Drew (2018b) treated them as probable synonyms and we here formally place B. luteicinctuta Ito, 2011, as a new synonym of B. yoshimotoi (Hardy, 1973). The holotype of luteicinctuta and the specimen recorded above remain the only known females. Bactrocera yoshimotoi is now known from Vietnam, Thailand, Bhutan, Nepal and Northern India (Himachal Pradesh).
