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 : 23-24

Megaselia haddadi n. sp.

( Figs 140–151 )

Material examined. Holotype male, West Azerbaijan province, Khoy city, Evogli region, 38°42.436’N, 45°12.246’E, 968 m, Malaise trap, 26.ix.2013, S. Khaghaninia (63, CUMZ—13-90) . Paratype: 1 male, locality data as the holotype ( ICHMM) .

Description. Male. Whole fly as Fig. 140 . Frons as Fig. 141 , without microtrichia except at edges ( Fig. 142 ). Cheek with 2 bristles and jowl with 2 that are longer and more robust. Antennae, palps and proboscis as Fig. 143 , the postpedicels being without SPS vesicles. Mesopleuron bare and with 2 notopleural bristles and no cleft in front of these. Scutellum with an anterior pair of small hairs and a posterior pair of bristles.Abdominal tergites brown and venter gray with fine hairs on segments 3–6. Hypopygium as Figs 144–148 , with at least hypandrial lobe (L in Fig. 147 ) but no right lobe. Legs yellow. Fore tarsus with posterodorsal hair palisade on segments 1–4 and 5 a little longer than 4 ( Fig. 149 ). Dorsal hair palisade of mid tibia extends about 0.73 times its length. Hairs below basal half of hind femur clearly longer than those of anteroventral row of outer half ( Fig. 150 ). Hind tibia with a dozen well differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings ( Fig. 151 ) 1.48 mm long. Costal index 0.44. Costal ratios 4.22: 2.04: 1. Costal cilia (of section 3) 0.09 mm long. Vein 3 hair 0.07 mm long. 2 unequal axillary bristles, the outermost being 0.10 mm long. Sc not reaching R1. Haltere knob yellow.

Recognition. In the key to the Megaselia males of the British Isles ( Disney 1989) it runs to couplet 224 lead 2 M. hayleyensis Disney, which was subsequently synonymised with M. quadriseta (Schmitz) , which had been described from the female only ( Buck & Disney 2001). However, M. quadriseta has a longer costal index and costal cilia, front tarsi with posterodorsal hair palisades on all five segments and the postpedicels with SPS vesicles. The subsequently described M. citrinella Buck runs to this couplet but it has an orange thorax, and also has a longer costal index and costal cilia. In Borgmeier’s (1966) to Nearctic Group VII it runs to couplet 12, but its costal index is too short. The subsequently described M. creasoni Hartop, Brown & Disney (2015) runs to the same couplet, but it has 3 notopleural bristles and the bristles at the tip of the proctor are clearly longer and more robust than those on cerci. It fails to fit any species from the rest of the world.

Etymology. Named after Professor Karim Haddad Irani-nejad. (Retired professor of Department of Plant Protection, Tabriz, Iran).
