Description.

Small fly (male 2.37-2.94 mm; female 3.0-3.39 mm) with grey pollinose body, yellow legs, and reticulate wing pattern. Head longer than high, frons with two frontal setae, two orbital setae (posterior orbital seta white), postocellar, postvertical seta white, lateral vertical seta white, medial vertical seta black, ocellar seta black and longer than frontal and orbital seta. Scutum grey pollinose with postpronotal lobe and notopleuron pale yellow and well-developed chaetotaxy, posterior notopleural seta black. Scutellum with two scutellar setae. Legs with fulvous black patches on mid and hind femur. Wing with reticulate pattern; pterostigma black without any hyaline spot or marking; apex of cell r4+5 with a hyaline spot. Abdomen grey pollinose; tergites 3-5 with a pair of quadrate, submedian, black markings.

Male postabdomen: Epandrium elongate, without clear delineation between epandrium and surstylus; lateral surstylar flange lacking; proctiger hyaline, shorter than epandrium. Epandrium and surstyli circular in outline in posterior view; medial surstylus with well-developed prensisetae. Phallus 1.05 mm long, with well sclerotised glans (0.25 mm) (Fig. 44 ).

Female postabdomen: Oviscape black (0.81 mm); eversible membrane (0.57 mm) with spicules on distal and proximal end inverted conical; distal spicules smaller compared with proximals; aculeus pointed (0.65 mm), without preapical indentions; spermatheca oval, with striations.

DNA barcode.

GenBank accession number MT019889 (1♀, INDIA: Karnataka, Bangalore, Attur, 29.v.2019, K. Sachin.)

Third instar larva (Figs 48-50 ).

Larva short (3.08 mm), elongate, fusiform, creamy white. Mouthhook pointed, with a well-developed preapical tooth as long as the apical mouthhook; ventral apodeme broader than mouthook; mandibular neck not prominent; dorsal apodeme dagger-shaped, pointed posteriorly; labial sclerite elongate; hypopharyngeal sclerite 2-2.5 × longer than broad; hypopharyngeal bridge pointed posteriorly; parastomal bar reaching beyond the middle of hypopharyngeal sclerite; ventral bridge of hypopharyngeal sclerite not prominent; anterior sclerite not prominent; dorsal cornua divided apically; ventral cornua with two branches. Anterior spiracle weakly sclerotised, with four tubules. Posterior spiracle with spiracular slits oval, slightly longer than wide, devoid of transverse striations; spiracles separated by a distance as equal to length of each slit; dorsal, ventral, and lateral spiracular bundle absent in specimen examined.

Host plants recorded during the study: flowers of Bidens pilosa L. and Cosmos sulphureus Cav. ( Asteraceae ).

Remarks.

This species occurs commonly from southern Europe to Africa, Asia, and Australia, and has been introduced into Hawaii ( Norrbom et al. 1999). Bezzi (1913), Hancock and McGuire (2002), Agarwal and Sueyoshi (2005), and David and Ramani (2011) recorded it from various locations in India, where it is widespread. Leg colour in many populations is variable ( Hardy and Drew 1996); in India, the femora are generally yellow with a black basal patch on mid and hind femora. Vestigial apical scutellar setae have been observed in some Australian populations ( Hardy and Drew 1996), but Indian specimens lack the apical pair.
