TACHINIDAE OF ORIENTAL REGION 127 



but the hosts were then unknown and it now appears more appropriate to associate 

 it with the anacamptomyiines (Crosskey, 1973ft : 91). The typical genus of the 

 group, Anacamptomyia Bischof, occurs in the Ethiopian Region and in Australia, 

 and will very probably be found at some time in the Oriental area: it is therefore 

 included in the key that follows.

Mid tibia with one ad seta. Propleural seta absent. Parafrontals clearly separated 

 by a well developed interfrontal area. Antennae not unusually small, antennal 

 axis above mid-eye level .......... 2 



Mid tibia with two strong ad setae. Propleural seta present. Parafrontals meeting 

 or almost so in mid line of the frons, interfrontal area obliterated. Antennae 

 very small, antennal axis below mid-eye level . . KORALLIOMYIA Mesnil 



Facial ridges bare (except for usual small setulae immediately above vibrissae).

Tribe STURMIINI 



The tribe Sturmiini as here recognized corresponds almost exactly to Mesnil's 

 (i949«-i952a) Sturmiina and to the sense of the tribe formulated in an earlier paper 

 (Crosskey, 1967ft), but it is likely that specialists will in future adopt the course 

 currently being formulated by Herting of assigning the various sturmiine genera 

 to a redefined Goniini and a redefined Eryciini. For the present it remains useful 

 to treat the Sturmiini as a separate tribe for practical purposes, particularly while 

 the rich fauna of the Oriental and Ethiopian Regions remains so little known and 

 studied. 



Most of the genera occurring in the Oriental Region are widespread throughout 

 the Old World tropics and subtropics, and when a genus appears to be confined 

 to one particular Old World zoogeographical region it is usually only the result 

 of the great difficulties that exist in trying to define the genera of Sturmiini in a 

 satisfactory way. Some of the genera currently recognized (such as Pales and 

 Palexorista) are moderately distinctive, but others (such as Sisyropa) contain rather 

 heterogeneous collections of species and may be quite unnatural. The value of 

 certain morphological characteristics for the reliable diagnosis of natural genera 

 needs thorough investigation, for it seems at present that in some parts of the tribe 

 it would be possible to 'shake up' the characters presently used for generic definition 

 in different combinations and get equally convincing (or unconvincing) genera. 

 In particular it would be of interest to know whether the presence of a single reclinate 

 orbital seta (in contrast to more than one pair) is really of such significance as it 

 appears. Mesnil (1949a : ioi, key couplet 12) used this character to differentiate 

 two major groups of genera, and this course has been followed by Crosskey (1967ft : 

 40) and in the present work, but there is no doubt that use of this character does 

 split apart some forms that on the whole facies appear so alike that they ought
