TACHINIDAE OF ORIENTAL REGION 55 



7 Parafacial with a row of several very strong downcurved setae on its whole height 



WAGNERIINI (p. 68) 



- Parafacial bare or haired but without strong setae (except in Voria with a very 



strong seta at the upper end near the bottom of the frontal row) ... 8 



8 Fore coxa haired on the whole (or almost the whole) of its inner anterior surface 



(similar to Text-fig. 140) .......... 9 



- Fore coxa bare on most of its inner anterior surface . . . . . . 12 



9 Vein R 1 setulose on nearly all its length and vein i? 1+5 setulose almost as far as or 



beyond r-m. ............ 10 



- Vein i? t bare and vein R i + i with a few hairs or setulae confined to the basal node . 1 1 



10 Arista plumose. Vein Cu 1 with the last section subequal in length to m-cu and the 



latter not unusually oblique, o" frons narrower than that of $ and without 

 proclinate orbital setae ..... THELAIRINI (part) (p. 74) 



- Arista bare. Vein Cu Y with the last section very much longer than m-cu and the 



latter exceptionally oblique (e.g. as Text-fig. 92). o* an d ? frons of equal width 



and both with proclinate orbital setae ..... VORIINI (p. 65) 



11 Eyes haired. Scutellum with four or more pairs of marginal setae. Epistome 



normal. Lower calypter with the upper surface extensively haired or at least 

 with hairs near the outer edge. Head profile typically as Text-fig. 59 



NEMORAEINI (p. 89) 



- Eyes bare. Scutellum with three pairs of marginal setae. Epistome constricted 



to a long narrow strip by approximation of the subfacial regions (Text-fig. 68). 

 Lower calypter bare. Head profile as Text-fig. 40 . MICROPHTHALMIA (p. 77) 



12 Supra-alar region of the scutum with one strong isolated seta, the first sa (pra and 



second sa absent). One or two post ia setae. Pallid luteous or reddish brown 

 forms with sparse stubby parafacial hairing. [Parasites of adult Scarabaeoidea] 



PALPOSTOMATINI (p. 57) 



- Supra-alar region of the scutum with two or three setae of varied size, sometimes 



supernumeraries in addition (pra and second sa nearly always both present even if 

 very small, very rarely both missing as in occasional minthoines). Two or three 

 post ia setae (sometimes very fine). Not such forms. [Not parasites of Scara- 

 baeoidea] ............. 13 



13 Epistome prominent, warped forwards from the face and visible in front of the 



vibrissal insertions when the head seen in profile (but not always strongly so) (e.g. 

 as Text-figs 45, 46, 48, 49) ; vibrissae usually inserted conspicuously above the 

 level of the epistomal margin . . . . . . . . . 14 



- Epistome not prominent, invisible or only just visible in front of the vibrissal 



insertions when the head seen in profile (usually in much the same plane as the 

 face) (e.g. as Text-figs 35, 41, 42, 44) ; vibrissae usually inserted on a level with the 

 epistomal margin ........... 17 



14 Scutellum with two or three pairs of marginal setae. Humeral callus with two or 



three setae (except in Thelairoleskia and occasional specimen of Demoticoides with 



four or five). Eyes usually bare. Three post dc setae . . LESKIINI (p. 91) 



- Scutellum with four or more pairs of marginal setae. Humeral callus with four or 



more differentiated setae (occasional specimen with only three). Eyes haired 

 (except in Paropesia). Three or four post dc setae . . . . . . 15 



15 Abdominal Ti + 2 excavate to its hind margin. Three post ia setae (aberrantly 



only two in some specimens of J anthinomyia but then the anterior one far removed 

 from the transverse suture and much closer to the posterior one). Eyes densely 

 haired (e.g. as Text-fig. 49). Hind tibia with or without pv apical seta. . . 16 



- Abdominal Ti + 2 not excavate to its hind margin. Two post ia setae (subequal 



in size and anterior one as close to or closer to the transverse suture as to the 

 posterior one). Eyes haired or bare. Hind tibia without pv apical seta 



PARERIGONINI (p. 97)
