Description

See Graham (1991).

Diagnosis

Scape, femora, mid and hind tibiae, and wing veins dark brown to black; female gaster 1.4-1.6 × as long as wide and with Gt7 transverse.

Distribution

Ireland, The Netherlands, United Kingdom ( Graham 1991), Sweden ( Hedqvist 2003) and France (new record).

Ecology

Host

Unknown.

Additional material examined

Type material: lectotypes ♀ of C. sinope (type no. 5.1935), C. hippis (type no. 5.1934), C. agathocles (type no. 5.1936), C. rapo (type no. 5.1937), all in NHM. Additional material: France, 3♀ (G). Sweden, Skåne & Öland, 3♀ (MZLU).

Remarks

In the barcoded nontype material analysed, there are three groups (ACM5794, ADP1347 and ACT4395), each represented by a single female specimen. The barcode strongly indicates that these are three different species, but they are not possible to separate by their morphology. Morphologically, all three specimens agree well with the type of T. sinope . Since we do not have any molecular information from the types of, and under, this species, it is not possible to identify these "barcode species" better than to T. sinope , even though they probably represent different species. Therefore, we conclude that T. sinope is an aggregate of morphologically-inseparable species.
