Ophion tournieri Vollenhoven, 1879: 61 , pl. 39; syn. nov. Henicospilus rossicus Kokujev, 1907: 170 ; lectotype Ƌ, ZIN, photos examined; syn. nov. Enicospilus contributus Shestakov, 1926: 256 ; syn. nov. Enicospilus repentinus – misidentification ( Gauld 1973 ). Status As described in the “Taxonomy of British Enicospilus ” section above, the lectotype male of Ophion merdarius is a specimen of the species usually called E. tournieri . The (probably non-British) female paralectotype is a specimen of Enicospilus adustus (i.e., the usual interpretation of the name), so the choice of lectotype was unfortunate. We have not examined type material of Ophion tournieri or Enicospilus contributus as these types cannot be located; instead we have followed the synonymies (under tournieri ) of Aubert (1962 , 1964 ) and Viktorov (1957) . The type of E. contributus should be in ZIN but could not be located (A. Khalaim, pers. comm.). The whereabouts of the type male of O. tournieri is a mystery; Townes et al. (1965) report the type depository as the Muséum national d’Histoire naturelle, Paris, but it cannot be found there (A. Touret-Alby, pers. comm.) and it seems unlikely when most of the Vollenhoven’s types were deposited in Dutch collections. There is also no trace of a type in Naturalis, Leiden (F. Bakker, pers. comm.), which includes the former Amsterdam collections. The type locality of Switzerland makes it likely that O. tournieri is a synonym of E. merdarius rather than E. cruciator , described from Turkmenistan and apparently more of a species of hot, dry climates (judging by published records and the collections of BMNH). Fig. 12. Enicospilus inflexus ( Ratzeburg, 1844 ) , ♀, Tredinnick Stack, England, BMNH(E) 962205, habitus. Scale bar = 10 mm. Restricted to a few coastal sites in England and Scotland . Only reared from Agrotis ripae (Hübner, 1823) (Noctuidae) (7 rearings), which inhabits the strandlines of sandy beaches and is very localised. The apparent host specificity of E. merdarius may be a result of the restricted noctuid fauna in its habitat. Gauld (1973) recorded E. repentinus as a British species but, based on his description of the species as being coastal, and the lack of true E. repentinus in the BMNH collections until recently, it seems he was describing E. merdarius ; in fact, Sperring (1952) had already published on E. tournieri as a British species, with a host record (specimens in BMNH and BENHS).

SCOTLAND : 1 Ƌ, St Cyrus NNR ( VC 91), ex A. ripae em. Jul. 1993 (A.J. Halstead) ( NMS ). Additional material in NMS BULGARIA : 6 ♀♀ , 1 Ƌ, Aksakovo (C.W. Plant) ( NMS ). The lectotype Ƌ was supposedly collected in Netley, Shropshire ( Fitton 1984 ), but this locality has been ascribed to most of the British material sent by F.W. Hope to J.L.C. Gravenhorst and seems very unlikely to be the actual collection locality for this sand dune inhabitant: entomologists of that period seemed often to name their home town, presumably to identify specimens as theirs, on what might otherwise be taken as data labels (which were, to say the least, unfashionable at the time). Remarks Most similar in the British fauna to E. repentinus but larger (52–58 flagellar segments, n = 10, modal value 52) and with distinct differences in fore wing sclerites and venation; also the propodeum has rather different sculpture, with the rugosity more raised and thus making it less shiny than in E. repentinus . Unlike in E. repentinus , there are some rather vaguely defined pale yellow patches on the mesosoma ( Fig. 13A ). The non-British Enicospilus cruciator is similar and the two species may well be confused in collections. Judging by Viktorov’s (1957) key and photographs of a female and male of the type series, E. cruciator differs from E. merdarius in the longer, less narrowed temples (in dorsal view of the head) and the larger ocellar-ocular gap.
