Spilomalus quadrinota (Walker) Graham, 1956 : 88-89, ?• 



Type material. Lectotype $ designated by Graham (1956 : 89) ; the species 

 was redescribed in the same paper (ibid. : 88-89). 



Britain: rare, apparently associated with sandy habitats, particularly on the 

 coast. It has also been recorded from Sardinia (Secretariat, etc., 1966 : 121, 125) 

 but I have not seen the specimens. Imagines July-Sept. 



Biology. The specimens recorded from Sardinia were reared from Auletobius 

 politus Serv. (Col., Curculionidae).

This is probably a valid species. The female differs from that of quadrinota in 

 having the antennal flagellum more slender, proximally not stouter than the 

 pedicellus ; pronotum, mesoscutum, and scutellum more finely reticulate and more 

 matt, possibly also with more numerous hairs ; fore wing extensively yellowish 

 infumate, with the spots more or less joined.

Spintherus is very close to Habrocytus Thomson and Pteromalus Swederus. It 

 differs from Habrocytus chiefly in having 4 teeth in both mandibles. The long 

 hypopygium, extending distinctly beyond the middle of the gaster, of female 

 Spintherus distinguishes them from all female Habrocytus except those of platyphilus 

 and crassicornis ; those species, however, have a large reticulate propodeal nucha 

 and distinct, plicae, whereas the nucha of Spintherus is very short and weakly 

 sculptured, and the plicae are distinct only posteriorly. Spintherus differs from 

 Pteromalus in its propodeal characters (short, weakly sculptured nucha, indistinct 

 plicae, and smaller spiracles) and in the longer hypopygium of the female.
