Khameneh, Roya Namaki, Khaghaninia, Samad, Disney, R. Henry L. & Maleki-Ravasan, Naseh, 2019, Twenty one new species of Megaselia Rondani (Diptera: Phoridae) from Iran, Zootaxa 4711 (1), pp. 1-50 : 47-49

Megaselia zarghanii n. sp.

( Figs 283–296 )

Material examined. Holotype male, West Azerbaijan province, Mahabad city, Ghalate-shah region, 36°46.01’N, 45°22.37’E, 1605 m, grassland, 19.VI.2017, S. Khaghaninia (40, CUMZ—13-96) . Paratypes: 2 males, locality data as the holotype ( ICHMM) .

Description. Male. Whole fly as Fig. 283 . Frons as Fig. 284 , with microtrichia restricted to edges ( Fig. 285 ). Cheek with 5 bristles and jowl with 2 that are longer and more robust. Postpedicels, which lack SPS vesicles, palps and proboscis as Fig. 286 , the labella with only a few short spinules below. Thorax brown. Two notopleural bristles, with no cleft in front of these, and mesopleuron with short hairs ( Fig. 287 ). Scutellum with 4 bristles and a pair of hairs ( Fig. 288 ). Abdominal tergites brown with numerous fine hairs, with are a little longer at rear of T6 ( Fig. 289 ). Venter brown, and with hairs on segments 3–6. Hypopygium as Figs 289–292 , the hypandrium having a left lobe only but the bristle each side longer than usual ( Figs 291 & 292 ). Legs brown. Fore tarsus with posterodorsal hair palisade on segments 1–4 and 5 clearly longer than 4 ( Fig. 293 ) and basitarsis with rows of small spinules ( Fig. 294 ). Dorsal hair palisade of mid tibia extends about 0.63 times its length. Hairs below basal half of hind femur longer than those of anteroventral row of outer half ( Fig. 295 ). Hind tibia with 13–15 moderately differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings ( Fig. 296 ) 1.69 mm long. Costal index 0.44. Costal ratios 3.82: x1.47: 1. Costal cilia (of section 3) 0.12 mm long. No vein 3 hair. 4 axillary bristles, the outermost being 0.13 mm long. Sc not reaching R1. Haltere brown.

Recognition. In the key to the Megaselia males of the British Isles ( Disney 1989) it runs to couplet 72 lead 1 M. simulans (Wood), but the brown legs and haltere rule out this species. In the key of Schmitz (1956) to Abteilung I it runs couplets 14 or 18 but its costa and costal cilia are too short. In Borgmeier’s (1964) key to Nearctic species Group I it runs to couplet 13, lead 1 M. fenestrata (Malloch), but its palps are yellow and legs are yellowish.

Etymology. Named after Dr. Ebrahim Zarghani (Former Ph.D. student of Prof. Khaghaninia).
