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).

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).

, 1 Ƌ, Aksakovo (C.W. Plant) (

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.
