88 R. W. CROSSKEY 



A species (apparently undescribed) of the genus represented by a specimen in BMNH 

 from east Tibet has a head profile similar to that of certain minthoines in which 

 the face is longer and the gena deeper than usual, and has the fore tarsi very notice- 

 ably enlarged (though less obviously flattened than in minthoines generally). 

 Placement of Austrophasiopsis in Minthoini, it must be emphasized, is a very 

 tentative measure and could well prove quite inapposite when clearer evidence of 

 affinity (e.g. from host relations) becomes available. 



The minthoines parasitize Lepidoptera belonging to families such as the Oeco- 

 phoridae, Pyralidae and Tineidae, but there are very few host records and none 

 from the Oriental Region (to the best of my knowledge). 



Key to Oriental Genera of MINTHOINI 



Wing with cell R b closed and long-petiolate (the petiole at least twice as long as r-m) . 2 



Wing with cell R 5 open or just closed at the margin (no petiole) .... 3 



Palpi absent or minute and papilliform. Setae of body and legs very weakly 

 differentiated or completely undeveloped (vestiture therefore largely or wholly 

 hair-like). Abdomen rotund, usually unicolorous orange. Costa with its entire 

 vestiture hair-like and the costal spine undifferentiated. Calyptrae broad, their 

 inner margins close to the scutellum . . AUSTROPHASIOPSIS Townsend 



Palpi present, long and slender. Setae of body and legs strong (i.e. a normal 

 minthoine chaetotaxy fully developed). Abdomen subfusiform, black or bicolorous 

 black and reddish yellow. Costa with the usual spiniform setulae as well as hairs 

 along its length and the costal spine very strong. Calyptrae small and rounded, 

 widely diverging from the scutellum . . DOLICHOPODOMINTHO Townsend 



Two post dc setae (widely separated). <£ abdomen with a slender tail-like apex 

 formed by the attenuation of T5. Posteroventral declivity of the thorax com- 

 pletely sclerotized. Basal node of f? 4 _,. 5 bare. Apical scutellar setae, when present, 

 very fine and diverging . . . . . . DOLICHOCOXYS Townsend 



Three post dc setae. <$ abdomen without a tail-like prolongation of T5. Postero- 

 ventral declivity of the thorax membranous medially. Basal node of R i+5 with 

 at least one small setula. Apical scutellar setae, when present, of varied size but 

 crossed ............. 4 



Facial length much greater than the frontal length (Text-fig. 41), the antennae 

 correspondingly elongate (third segment 5-6 times as long as second segment and 

 very nearly reaching the epistome). Facial ridge sparsely setose or setulose on 

 lower half or third. Prescutum without fully differentiated prst acr setae. Arista 

 almost bare. Scutellum with very strong apical setae that are larger than the 

 rather weak basal setae. $ fore tarsus strongly laterally compressed and with the 

 last segment exceptionally enlarged (equal in length to the three preceding segments 

 together, Text-fig. 146). Prosternum bare or with one or two small downwardly 

 directed setulae on each side. Basal node of i? 4+5 with one rather strong setula 



MELANASOMYIA Malloch 



Facial length less than or at most subequal to the frontal length (Text-figs 42 & 43), 

 the antennae of corresponding medium size (third segment not more than four times 

 as long as second segment and often falling short of the epistome). Facial ridges 

 bare except for the usual small setulae immediately above the vibrissae. Prescutum 

 with one pair of prst acr setae. Arista plumose or pubescent. Scutellum with or 

 without apical setae, if present of varied size. $ fore tarsus of varied form but 

 last segment only as long as the penultimate segment. Prosternum bare. Basal 

 node of /? 4+5 with one or a few minute hair-like setulae ..... 5
