PABT 1 



of the lower half of face and of these at least 4 elements 

 may be situated along the sides of the epistoma; upper 

 face with 12 to 15 fine hairs, only moderately long. 

 In others the mystax may consist of long, quite stiff 

 hairs, relatively slender and the whole face, except 

 narrowly along the lateral margin with comparatively 

 abundant, long, fine pile. Front moderately long and 

 also as wide as the upper face ; it bears a tuft of fine 

 pile laterally below the ocelli. The ocellarium is rather 

 large but not very high, its sides vertical; it bears 

 large ocelli and 3 pairs of comparatively long, pale, 

 stout bristles; there are 1 pair between, 1 pair in front, 

 and another pair behind the posterior ocelli. 



Thorax : The mesonotum has a single row of sparse, 

 long, curled, brownish white acrostical elements with 

 a single row of extremely long, unusually stout, brown- 

 ish yellow, backwardly curved, dorsocentral bristles; 

 the anterior apex of the row may have an extra bristle. 

 All the lateral bristles are quite stout, long, brownish 

 yellow, and consist of 3 humeral, 3 notopleural, 2 

 supraalar, 1 postalar, and 2 pairs of bristles on the 

 scutellar margin. The dorsocentral bristles begin op- 

 posite the humerus, and in front of the suture are 3 

 pairs of exceptionally long, strong bristles which are 

 translucent yellowish white. The scutellum is rather 

 strongly flattened but the margin slightly convex, the 

 whole disc micropubescent. Humerus with long pile; 

 propleuron without bristles, the pile long and fine; 

 mesopleuron, pteropleuron, and hypopleuron apilose. 

 The stemopleuron has only 2 or 3 hairs anteriorly. 

 Whole thorax minutely appressed pubescent, meta- 

 pleuron with a single vertical row of 5 or 6 bristles. 

 Metanotal slopes without pile. Lateral metasternum 

 for the most of its length with numerous, fine hairs; 

 ventral metasternum narrow, chitinized, isolated, with 

 a few long, fine hairs. First sternite apilose; post- 

 metacoxal area membranous and pollinose; lateral 

 metastemum micropubescent only. Tegula pubescent 

 only. 



Legs : The femur moderately stout, with dense, short, 

 flat appressed yellow pile and with 3 stout, brownish, 

 dorsolateral bristles; it also has a pair of longer, stout, 

 dorsal subapical bristles. Hind tibia with moderately 

 long, very stout, greyish brown to yellowish brown, 

 slightly oblique bristles. It has 2 lateral bristles on 

 the basal half, 3 posteroventral bristles situated at the 

 middle, and 2 on the outer fourth, also 4 dorsal bristles. 

 Middle femur with a stout, anterior bristle on the basal 

 third and a dorsoapical pair and a weak lateral apical 

 bristle. Middle tibia with 2 moderate, rather long, 

 dorsal and 2 or 3 shorter, dorsal bristles, besides 5 quite 

 long, oblique, stout, dorsal bristles and a double, ventral 

 row of shorter, divergent bristles. Anterior femur 

 with only 1 bristle at the apex posteriorly. Anterior 

 tibia with brownish yellow bristles, 4 rather short, stout, 

 dorsal, 4 posterodorsal, 4 posterior, and 4 ventral. 

 Apex with a conspicuous, strongly curved, stout, 

 posteroventral, black spine; basitarsus not modified. 

 Anterior basitarsus with 1 long posterobasal, 2 long 

 posteroapical, and 1 quite long posteroventral brown- 



ish yellow bristle. Claws long, but little curved, ex- 

 cept near the apex, and moderately sharp. Pulvilli 

 large; empodium long and strongly stiffened near the 

 base. 



Wings : The wings are slightly narrowed. Marginal 

 cell widely open ; the second submarginal cell relatively 

 narrow at the wing margin. All posterior cells are 

 widely open and the medial crossvein is barely longer 

 than the upper section of the anterior intercalary vein. 

 The middle end vein of the second basal cell is reduced 

 in length and the anal cell is closed and stalked. Alula 

 small and ambient vein complete. 



Abdomen : The basal tergite is as wide as the mesono- 

 tum but narrowed a little posteriorly; remainder of 

 abdomen with nearly parallel sides, robust but strongly 

 cylindroid ; the abdomen is convex but slightly flattened 

 across the middles of the first 2 or 3 tergites. First 

 tergite a little more than half as long as the second; 

 laterally it bears a cluster of 6 or 7 moderately long, 

 rather stout, yellow bristles. All other abdominal 

 pile comparatively short, flat appressed, fine and yel- 

 lowish. Males with seven tergites, the last two reduced, 

 the seventh from a fifth to a sixth as long as the pre- 

 ceding tergite, and the sixth only two-thirds as long 

 as the fifth ; second tergite a little constricted dorsally 

 and narrowly along the base but not laterally. Females 

 with eight tergites of gradually decreasing length ; the 

 eighth is one-third the length of the seventh. Female 

 terminalia quite short, in profile but little evident, with 

 on either side a row of blunt, brownish spines. 



Distribution. Palaearctic: Paraplxainartania syriaca 

 Schiner (1867).

Annamyia Pritchard, Proc. Ent. Soc. "Washington, vol. 43, p. 

 131, 1941. Type of genus : Annamyia maren Pritchard, 

 1941, by original designation. 



These flies are of medium size and related to 

 Aphamartania Schiner and characterized by the plane 

 face, which is moderately but gradually produced below 

 with strong bristles composing the mystax. The ante- 

 rior tarsus is unusually long, twice as long as the ante- 

 rior tibia. These characters together with the diver- 

 gent face also separate the genus from Par aphamar- 

 tania Engel. All three genera in the males have an 

 enlarged terminalia with swollen bulbous hypandrium. 

 Length 13 mm. 



Head, lateral aspect: The face is moderately pro- 

 duced on the lower part and rises gently from the base 

 of the antenna, with the surface nearly plane; it is 

 slightly recessive on the lowest sixth, just above the 

 epistoma. The eye is high and only shallowly convex 

 anteriorly and posteriorly, its length a little greater 

 upon the ventral half. The occiput is not strongly 

 developed but is thicker below ; it follows the curvature 

 of the eye and is quite reduced dorsally. The pile of 

 the occiput is coarse and only moderately abundant
