segments laterally with moderately abundant, fine, 

 long pile; no bristles present. The male terminalia 

 are swollen and exceptionally large, but not rotate. 

 The epandrium is undivided, with large flat, triangular 

 dorsal plate, the ventral element large, bulbous and 

 swollen. Female unknown. 



Distribution: Neotropical: Annamyia maren Prit- 

 chard (1941).

Hodophylax James, Anier. Mus. Novltates, no. 596, p. 1, 1933. 

 Type of genus : Hodophylax aridus James, 1933, by original 

 designation. 



Small, quite stout flies of sparse, short, appressed 

 pile and stout legs. Anterior tibia with a weak, 

 curved, spinous bristle. Pulvilli absent; empodium 

 reduced. Length 7 mm. 



Head, lateral aspect: The face in profile is quite 

 short, slightly more jirominent below. The eyes are 

 distinctly narrower on the upper half without reces- 

 sion, either anteriorly or posteriorly. The occiput is 

 prominent on the lower half of the head, obliterated 

 near the bottom of the eye and gradually reduced in 

 thickness on the upper portion of the head. Occipital 

 bristles begin at the middle of the head and consist of 

 7 or 8 pairs of weak, short bristles ; occipital pile quite 

 scanty, chiefly restricted to the lower half of the occi- 

 put with only a few hairs on the upper portion, except 

 immediately behind the ocelli where they are more 

 numerous. The proboscis is extremely short and does 

 not project beyond the face. It is chiefly directed for- 

 ward and only slightly oblique. It is rather strongly 

 compressed laterally, robust, with bluntly rounded 

 apex; it bears some fine pile apically and on the ven- 

 tral margin of the outer half; the basal half is without 

 pile. Palpus small, short, of two segments. First seg- 

 ment excavated, second somewhat swollen, not porate, 

 but with a few fine hairs. 



The antenna is attached just above the middle of the 

 head ; it is moderately long and slender, first two seg- 

 ments of nearly equal length, second slightly wider 

 apically. The third segment is a little more than twice 

 as long as the first two segments combined, slightly 

 less wide than the first segment; it is cylindrical, of 

 uniform width to the middle then very slightly nar- 

 rowed to the apex. The third segment bears a single, 

 rather long microsegment which carries a minute apical 

 spine, and is held in a slightly oblique position. First 

 segment with 1 single stiff hair dorsally and 2 vent- 

 rally ; second segment with 2 minute setae dorsally and 

 with 1 quite long, moderately stout bristle ventrally 

 which is considerably longer than the first 2 segments 

 combined. 



Head, anterior aspect: The face below the antenna 

 is two-sevenths the head width and very slightly di- 

 vergent below. Subepistomal area is moderately large 

 but distinctly horizontal, shallowly concave and bare. 



Face densely micropubescent with a few scattered, 

 curled hairs laterally and beneath the antenna. On 

 the lower margin transversely are 8 to 10 pairs of 

 rather short, stout, pale bristles. Front slightly diver- 

 gent, the vertex scarcely convergent. The front bears 

 along the eye margin a few stiff, curled hairs and a 

 few in the middle of each side and is otherwise densely 

 micropubescent. Vertex only slightly excavated, the 

 ocellarium large but low, the ocelli large, the tubercle 

 bearing 1 to 2 pairs of slender bristles, and with 1 or 

 2 stiff hairs behind the ocelli. The eyes are strongly 

 flattened in front, the mediocentral facets greatly 

 enlarged. 



Thorax : The whole thorax except for the posterior 

 sternopleuron, the lower pteropleuron and the middle 

 of the postalar region is densely appressed micropu- 

 bescent. Pile of thorax moderately long, but quite flat 

 appressed. Acrostical and dorsocentral bristles weakly 

 differentiated with 4 somewhat longer, stouter pairs of 

 bristles posteriorly. Humerus pubescent only. There 

 are stout but rather short bristles present as follows: 



2 notopleural, 3 to 4 supraalar, 2 postalar, 2 pairs on 

 the scutellum. Scutellar disc shallowly convex, 

 densely pubescent, without pile. Propleuron with stiff, 

 coarse, bristly pile. Anterior collar with long pile 

 only. The upper posterior section laterally has a dense, 

 appressed mat of posteriorly directed, long, bristly 

 hair. Upper anterior mesopleuron with stiff, ap- 

 without pile. Metapleuron with a vertical band of 

 nearly 20 long, rather stiff bristles. Metanotal slopes 

 pressed, bristly setae. Pteropleuron and hypopleuron 

 micropubescent only. Metastemal slopes with fine 

 pile. Metastemum bare, postmetacoxal area mem- 

 branous. Tegula pubescent only. Prosternum 

 dissociated. 



Legs: The legs are stout, the pile is rather long, 

 coarse, flat appressed, almost bristly setate in appear- 

 ance. Pile is almost wholly absent on the medial and 

 ventral surfaces of the hind femur, the ventral and 

 anterior surfaces of the other femora. Hind femur 

 with 2 short, weak, dorsoapical and 7 short, weak dor- 

 solateral bristles. Hind tibia unusually stout and 

 bearing longer, stouter bristles, 7 dorsal, 4 dorsolateral 

 which are quite short, 4 lateral with an additional 

 lateral row lower down containing 4 or 5 bristles, and 

 a ventrolateral row of 4 longer bristles. Apex with 1 

 dorsolateral, 2 lateral, 5 ventral bristles. Middle fe- 

 mur with 2 weak bristles dorsally at the apex, 1 lat- 

 erally and 1 slightly stouter bristle lateral and sub- 

 apical. Middle tibia has 5 anterior, 3 minute dorsal, 

 8 longer, stout, oblique, posterior bristles, and 3 long, 

 ventral bristles. Anterior femur with 2 small, weak 

 bristles posteroapically ; the tibia with 4 short, weak, 

 dorsal bristles, 6 short anterior, 7 longer posterior, and 



3 still longer posteroventral bristles. The anterior tibia 

 has a weak, strongly curved, apical spine. Tarsi end in 

 long, slender claws which are gently arched, curved 

 and sharp. Pulvilli absent; anterior empodium weak 

 and reduced to a third of the length of the claw ; pos- 

 terior empodium two-thirds of the length of the claw.
