TACHINIDAE OF ORIENTAL REGION 129 



Key to Oriental Genera of STURMIINI 



Head with two or three pairs of reclinate orbital setae ..... 2 



Head with one pair of reclinate orbital setae (strong and isolated, but $. sometimes 



with a smaller erect seta ventrad and mesad of the true reclinate orbital) . . 19 



Eyes densely haired (hairing conspicuous and usually long) ..... 3 



Eyes bare or almost so (some very short sparse inconspicuous hairs occasionally 



present) ............. 8 



Parafacials completely haired STURMIOPSIS Townsend 



Parafacials bare (at most a very few minute hairs present adjacent to the lowest 



frontal setae) ............ 4 



Basal node of /? 4 f5 with at least two or three small setulae. Facial ridges normal, 

 obviously raised in relation to the plane of the face; either bare or with strong 

 downcurved setae ........... 5 



Basal node of /? 44 5 with one very lon^ strong curved setula. Facial ridges unusually 

 wide and flat ventrally, very little raised in relation to the face; bearing some 

 very fine hairs on the lower half close to the para facial (inconspicuous in 9)- 

 [o* abdomen almost entirely silver-white pollinose on the dorsum] 



ISOCHAETINA Mesnil 



Facial ndges with very strong downcurved setae on most of their height, the 

 ridges widely visible in profile. Scutellum with erect spiniform vestiture near 

 the apex TAKANOMYIA Mesnil 



Facial ridges bare (except for the usual small setulae near the \ ibrissae), not visible 



in profile. Scutellum without such spiniform vestiture ..... 6 



Two or three sternopleural setae. Apical scutellar setae horizontal or almost so. 



Second aristal segment not elongate ........ 7 



Four sternopleural setae. Apical scutellar setae directed almost straight upwards. 

 Second aristal segment obviously elongate (2'5-4-o times as lon<^ as broad) 



PARADRINO Mesnil 



Mid tibia with one or two ad setae. Intermediate abdominal tergites usually with 

 small erect discal setae differentiated from the hairing. Hairing of the eyes 

 long. Prescutum and scutum bright yellow pollinose (almost uniformly so or 

 with bold black vittae), scutellum either uniformly black or with black basal 

 half and yellow-pollinose apical half . . . CALOZENILLIA Townsend 



Mid tibia with at least three ad setae. Intermediate abdominal tergites without 

 discal setae. Hairing of the eyes moderately dense but short (much shorter 

 than normal in hairy-eyed forms). Dorsum of thorax without conspicuously 

 contrasting black and yellow appearance .... EUHYGIA Mesnil 



Mid tibia with two or more ad setae ........ 9 



Mid tibia with one ad seta .......... 14 



Two or three sternopleural setae. Mid tibia with at least three ad setae clearly 



differentiated ............ 10 



Four sternopleural setae (2 + 2). Mid tibia with two ad setae . . . . 13 



Presternum bare. Facial ridges with strong downcurved setae on most of their 



height BLEPHARELLA Macquart 



Presternum haired or setulose. Facial ridges bare or at most with small weak 



setulae confined to the lower two-fifths or less . . . . . . 11 



Antennal axis about level with the eye-middle. Parafacial narrowing towards the 

 lower end and less than twice as wide as third antennal segment. Head seen 

 from in front with the facial ridges appearing strongly bowed apart; in profile 

 the ridge only narrowly visible. Epistome visible in profile and distinctly warped 

 forwards from the face .......... 12 



Antennal axis obviously above the level of the eye-middle. Parafacial not narrowing 

 towards the lower end (sometimes even widening) and more than twice as wide
