MOKRZECKIA Mokrzecki 



Mokrzeckia Mokrzecki, 1933 : 143. Type-species: Pteromalus pini Hartig, 1838, by monotypy. 



Mokrzeckia Morawski, 1934 : 18-20. 



Beierina Delucchi, 1958 : 271. Type-species : Pteromalus pini Hartig by orginal designation. 



Mokrzeckia Mokrzecki ; Boucek, 1961 : 74. 



Mokrzeckia Mokrzecki ; Peck et al., 1964 : 46. 



As Boucek (1961) has pointed out, the original diagnosis of Mokrzeckia was very 

 imperfect ; hence, as it was published after 1931, it may not be valid according to 

 the International Code of Zoological Nomenclature. This question can only be 

 decided by the International Commission ; meanwhile the name Mokrzeckia is 

 provisionally accepted. The genus Beirina was synonymized with it by Boucek 

 (1961).

 (Females) 



1 Anterior margin of clypeus (Text-fig. 355) deeply emarginate with a notch in the 

 middle of the emargination. Legs, including at least the fore coxae partly, yellow- 

 testaceous. Antenna with combined length of pedicellus and flagellum slightly 

 less than breadth of head ; flagellum testaceous or brownish, stout ; proximal 

 segments of funicle quadrate or very slightly longer than broad. Fore wing with 

 marginal vein 1-7 to 1-9 times as long as the stigmal vein ; basal cell, on upperside 

 of wing, with some hairs scattered over its upper half. Mesoscutum about twice as 

 broad as long, extremely finely reticulate. Median area of propodeum (Text-fig. 

 356) delicately reticulate, moderately shiny. Hind tibia with two spurs, but the 

 second is weak, hardly half as long as the first . . . pini (Hartig) (p. 478) 



- Anterior margin of clypeus shallowly emarginate. Coxae black with a metallic tinge ; 

 femora extensively infuscate. Antenna with combined length of pedicellus and 

 flagellum slightly greater than breadth of head ; flagellum (Text-fig. 357) fuscous, 

 more slender ; funicular segments slightly longer than broad, or at most the sixth 

 quadrate. Fore wing with marginal vein 1 -55 times as long as the stigmal vein ; 

 basal cell bare or virtually so. Mesoscutum hardly 1-7 times as broad as long, its 

 disc moderately coarsely reticulate. Median area of propodeum more strongly 

 reticulate, duller. Hind tibia with one spur .... obscura sp. n. (p. 479)
