Tetrastichus murcia (Walker, 1839)

Cirrospilus Walker 1839c:177. Lectotype ♂ in NHM, designated by Graham 1961:39, examined (Fig. 11). Combined to Tetrastichus by Walker 1848:146 and to Aprostocetus by Graham 1961:39 and back to Tetrastichus by Graham 1991:261.

Tetrastichus trichops Thomson 1878:282. Lectotype ♀ in MZLU, designated by Graham 1961:39, examined. Synonymised with T. murcia by Graham 1991:261.

Description

See Graham (1991).

Diagnosis

Female gaster with ovipositor sheaths projecting distinctly beyond apex of Gt7, length of projecting part about equal to length of hind basitarsus; setae on eyes very long, 0.8 × OD; distance between posterior ocelli relatively short, POL/OOL= 1.5-1.6.

Distribution

France, Germany, Sweden, United Kingdom ( Graham 1991), and Russia (new record).

Ecology

Host

Sargus ( Geosargus ) sp. ( Diptera : Stratiomyiidae ), endoparasitoid emerging from pupa ( Domenichini 1966). Larvae of Sargus develop in decaying matter, some in ulcers of elm trees, i.e. saprophagous ( Johannsen 1922).

Material examined

Type material: lectotypes ♂ of C. murcia (type no. 5.1944) and ♀ of T. trichops (type no. 4869:1). Additional material (4♀): France 2♀ (GD), Russia 1♀ (MZLU), Sweden 1♀ (SMTP).
