PTEROMALIDAE OF N.W. EUROPE 75 



SCUTELLISTA Motschulsky 



Scutellista Motschulsky, 1859 : 172, 177. Type-species : 5. cyanea Motschulsky, by monotypy. 



Aspidocoris Costa, 1863 : 25. Type-species : A. cyaneus Costa, by monotypy. 



Enargopelte Forster, 1878 : 62-63. Type-species : E. obscura Forster, by monotypy. 



Scutellista Motschulsky ; Ashmead, 1904 : 325, 326. 



Enargopelte [sic] Forster ; Ashmead, 1904 : 326. 



Scutellista Motschulsky ; Schmiedeknecht, 1909 : 304, 305. 



Enargopelte Forster ; Schmiedeknecht, 1909 : 304, 305-306. 



Scutellista Motschulsky ; Kurdjumov, 1912 : 331-332. 



Enargopelte Forster ; Masi, 1931 : 443-452. 



Scutellista Motschulsky ; Masi, 1931 : 456-459. 



Enargopelte Forster ; Kryger, 1943 : 78-81. 



Scutellista Motschulsky ; Nikol'skaya, 1952 : 234. 



Scutellista Motschulsky ; Peck, 1963 : 633-636. 



Scutellista Motschulsky ; Peck et al., 1964 : 32. 



I do not think that the differences between the species of Scutellista and Enargo- 

 pelte are great enough for these two entities to be regarded as distinct genera, 

 although they are treated as such by Peck et al. (1964 : 32). The two have more 

 recently been united by Boucek (1966 : 35). The European species need revision ; 

 but not having seen their types I am unable to do so. 



Provisional key to European species 

 (Females) 



This key is partly adapted from Masi's key to Enargopelte (1931 : 445). 



1 Fore wing with a subtriangular bare area about in the middle of its hind 



margin ; postmarginal vein distinctly shorter than the stigmal vein. 

 Scutellum about 2-5 times as long as the mesoscutum, overlapping about 

 half of the gaster. Length 1-5 to 4 mm. Antennal flagellum yellow 

 (Scutellista Mots., s.str.) .... cyanea Motschulsky (p. 76) 



- Fore wing wholly pilose except for a narrow line below the cubital vein ; 



postmarginal vein usually almost as long as the stigmal vein. Scutellum at 

 most twice as long as the mesoscutum, usually overlapping less than half 

 the gaster. Length 1 to 1 -8 mm. Antennal flagellum yellowish, brown, or 

 black (Enargopelte Forster) ......... 2 



2 (1) Antenna with first funicular segment as long as the second and about 1 -5 times 



as long as broad ; clava nearly as long as the whole funicle. Fore wing 

 with marginal vein about three times as long as the stigmal vein. Antennal 

 flagellum yellowish with the clava slightly darker above 



hispanica (Masi) (p. 77) 



- Antenna with first funicular segment slightly shorter than the second, quad- 



rate to slightly transverse ; clava not or only slightly longer than the three 

 preceding funicular segments together. Fore wing with marginal vein 

 about twice as long as the stigmal vein. Antennal flagellum usually brown 

 to black, sometimes paler proximally ....... 3 



3 (2) Vertex and upper part of frons with numerous distinct piliferous punctures 



amongst the reticulation. Length about 1 mm. obscura (Forster) (p. 76) 



- Vertex and frons with indistinct, weakly-impressed piliferous punctures 



amongst the reticulation. Length 1-5 to i-8 mm. or (f. minor) about 



1 mm. ........ nigra (Mercet) (p. 77)
