TACHINIDAE OF ORIENTAL REGION 35 



because examination of the holotype of Euthera burtti van Emden from Tanzania 

 shows that this nominal species is synonymous with E. mannii. (I have compared 

 the holotype of burtti with reliably named specimens of mannii from Greece and 

 can find no characters that justify the separation of burtti as a valid species: it is 

 accordingly placed herein as a new synonym.) 



The Euthera specimen from Ceylon that Townsend mentioned, judging from the 

 features that he cited, probably belongs to E. tuckeri Bezzi. Until now this species 

 has been recorded only from Africa (van Emden, 1960) and Pakistan (Anwar 

 Cheeta et al., 1973) but probably occurs more extensively. 



Shield-bugs of the family Pentatomidae (Hemiptera) are the hosts of Euthera 

 species but the host-relations are very poorly known and specimens of Euthera 

 are rare in museum collections. The paucity of material makes it difficult yet to 

 judge the extent of the geographical range of Euthera species, but it looks probable 

 that each species has a much wider distribution than has been thought. Probably 

 some species occur widely in different zoogeographical regions because of their 

 association with wide-ranging host species. The pentatomid Eysarcoris inconspicuus 

 Herrich-Schaffer for example, which is parasitized by E. tuckeri in Pakistan, occurs 

 in the Oriental Region, in southern Europe and in Africa, and may well prove to 

 be attacked by the same tachinid in Africa (at present there are no host records 

 for any African species of Euthera) . 



Host records for the area covered by the present work are those of Narayanan & 

 Ghai (1961), who recorded E. mannii from the New Delhi area of northern India 

 as parasitizing Halys dentatus Fabricius, and Anwar Cheeta et al. (1973), who 

 recorded E. tuckeri as a parasite of various pentatomids in Pakistan (see parasite- 

 host list, p. 289). (Some reared specimens of tuckeri from Eysarcoris inconspicuus 

 and Acrosternum graminea Fabricius in Pakistan are in the BMNH collection.)

 appearing slightly polished only on the sharp anterior edge. Wing with petiole

Note on the Unplaced Genus CYLINDROMYIELLA Malloch 



The genus Cylindromyiella Malloch is known only from the holotype specimen 

 of its type-species, C. bakeri Malloch, from the Philippines, and its relationships 

 with other Tachinidae are very obscure. Some of the features of the genus are
