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 : 24-26

Megaselia hejazii n. sp.

( Figs 152–164 )

Materrial examined. Holotype male, West Azerbaijan province, Khoy city, Pere region, 38°36.722’ N, 44°53.336’ E, 1323 m, grassland, 9.VII.2011, S. Khaghaninia (49, CUMZ—13-98) . Paratype: 1 male, locality data as the holotype ( ICHMM) .

Description. Male. Whole fly as Fig. 152 . Frons as Fig. 153 , with dense but very fine microtrichia largely restricted to the edges ( Fig. 154 ). Cheek with 5 bristles and jowl with 2 that are longer and more robust. Postpedicels, without SPS vesicles, palps and proboscis as Fig. 155 , the labella with lacking short spinules below. Thorax brown. 3 notopleural bristles and no cleft in front of these. Mesopleuron with hairs. Scutellum with an anterior pair of small hairs and a posterior pair of bristles. Abdominal tergites and venter gray with hairs on segments 5 and 6 only ( Fig. 156 ). Hypopygium as Figs 157–160 ). Legs brown to yellowish brown. Fore tarsus with posterodorsal hair palisade on segments 1–4 and 5 longer than 4 and basitarsus with at least one row of small spinules ( Figs 161–163 ). Dorsal hair palisade of mid tibia extends about 0.60 times its length. Hairs below basal half of hind femur at most ass long as those of the anteroventral row of outer half. Hind tibia with a dozen weakly differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings ( Fig. 164 ) 1.13 mm long. Costal index 0.38. Costal ratios 5.00: 1.14: 1. Costal cilia (of section 3) 0.09 mm long. Vein 3 hair 0.02 mm long. 2 axillary bristles, the outermost being 0.09 mm long. Sc not reaching R1. Haltere knob whitish yellow.

Recognition. In the key to the Megaselia males of the British Isles ( Disney 1989) it runs to couplet 71, where the choice depends on the number of rows of small spinules on the front basitarsus. As it seems to be a single row one proceeds to couplet 92. If one takes the alternative then one proceeds to couplet 86 lead 1 M. involuta (Wood), but its haltere knob is brown and its coatal index is about 0.44. From couplet 92 on proceeds to couplet 139 where the hypopygia are clearly different. 5 omitted or subsequently described species run to the same couplet, but all have the haltere knob brown and/or the costal index exceeding 0.45. In the Schmitz & Delage’s (1974) to Abteilung V it runs to couplet 5 where neither option applies. In Borgmeier’s (1964) key to Nearctic group V it runs to couplet 1 lead 1 M. semicrocea Borgmeier, but its epandrium has small hairs only.

Etymology. Named after Professor Mir Jalil Hejazi. (Professor of Department of Plant Protection, Tabriz, Iran).
