Mihályi, F.: Description of two new Fanniinae species from Hungary (Diptera, Muscidae)
Hennigomyia aenigmatica sp. n. rf , ?9 (Figs. l-IO) Male. Head (Fig. 1 -2) black, dusted silvery-gray on frons and facial orbits. Eyes very sparsely haired, in profile covering nearly whole head. Frons at vertex rather broad, varying between 1/4.6 and 1/6 head-breadth, mean 1/5.2. Number of frontal bristles 9-10, upper frontal bristles 2. Antennae black, third segment about 1.6 times as long as wide, 1.5-2 times longer than segment 2. Arista pubescent. Facial orbits and jowls narrow, half as wide as antenna! segment 3. Palpi black, widening at the end. Upper postocular cihation uniserial. Thorax black, seen from above dusted brownish-black, viewed from behind uniformly black, just before scutellum dusted ash-gray. Acrostichals uniformly biserial. Distance of ac rows half of ac — dc distances, behind suture distance growing to 1:1. Two well-developed prealars, frontal one longer, but less than half as long as second noto pleural. Abdomen (Fig. 3) black, gray-dusted on sides, with black marks in middle, widening towards hind-margin on tergits 2 -3, but narrow on third one, with merely a line on fifth. Male genitalia (Figs. 4-6) bulky, strongly developed, with a pair of disciform end-parts, armed with strong falciform black spines, directed posteriorad, discernible without preparation and rendering the species easily recognizable. Wings (Fig. 7) vitreous, veins light and darker brown. Squamae dirty-white, haltères light-brown. Legs completely black. Posteroventral setae of first femur thin, shorter than its diameter, first tibia without bristles before apical ones, rarely a weak anterodorsal present. Second femur with 8-10 anteroventrals and before tip about 6 closely set shorter ones and two rows of posteroventrals of about length of femur diameter ; middle tibia (Fig. 8) thickened in second 2/3 with rather long semi-erect hairs beneath (lacking in first third) and with 2-3 anterodorsals and 2 posterodorsals. Hind Figs. 1-2. Head of Hennigomyia aenigmatica sp. n., male.
