Etymology.
From the Latin flagellum (whip) and seta (bristle) referring to the delicate whip-like setae and setulae covering the scutum of the males.
Diagnosis.
Males can easily be distinguished from other species by their femora, pleura and scutum having some setae differentiated as delicate whip-like setulae, in combination with apically globular frontal and orbital setae. The female has the ovipositor with an atypical tergite 6, which is a fused, broad plate with a basal emargination, compared to the typical and, up to now, considered synapomorphic, slender paired plates of other Coenosia .
Description.
Male. Holotype ♂ measurements (mm): body length: 4.72; head: 0.92; thorax: 1.80; abdomen: 2.00; wing: 4.52; ratios (length/width): frontal plate 3.25.
Head ( Fig. 7 View Figures 7–10 ): Dichoptic. Eyes bare and somewhat reduced taking up ca. 45% of lateral head surface. Antennal scape bare; pedicel with dorsal suture along its length, with one strong setula and one weak setula on the dorsal inner surface; postpedicel not reaching past bottom third of eye, ca. 2 × length of pedicel. Arista located dorsally on postpedicel, bare. Palpus apically dilated ( Fig. 11 View Figures 11–14 ), dark brown in colour with apical gold-white hairs. Gena wide with dark marking apically, face projecting forwards. Mentum dark brown, glossy. Head grey-dusted throughout, with exception of silver-white-dusted frontal plate (black ground colour) and fronto-orbital plates. One pair of ocellar setae, 2 × length of ♀ ocellar setae. One pair of exceptionally long, inclinate, apically globular orbital setae, situated on a glossy, raised, tubercle; two pairs of inclinate apically globular frontal setae; analogous middle pair of three pairs of frontal setae found in ♀ reduced to same length and appearance as interstitial setulae. One pair of divergent post-ocellar setae, less than ½ the length of ocellar setae.
