Genus Goetheana Girault, 1920

Goetheana Girault, 1920 a: 97 . Type species: Goetheana shakespearei Girault, 1920 a , by monotypy.

Dasyscapus Gahan, 1927: 26 , 27. Type species: Dasyscapus parvipennis Gahan, 1927 , by monotypy. Synonymised under Goetheana by Girault 1930: 4.

Goetheana Girault : Boucek 1988: 734, 735; Schauff 1991: 54; Loomans & van Lenteren 1995: 137–146, 197.

Diagnosis: Body size very small (less than 0.8 mm); complete and straight suture present across vertex just behind posterior ocelli; mandible reduced (without teeth); antennal flagellum (in both sexes) with 2 funicle segments (F1 much smaller than F2, the latter superficially appears to be a part of clava), clava 3-segmented, usually with an apical spicula; scape of male antenna notably swollen in the majority of described species; notauli very narrow but distinct in slide-mounted specimens; midlobe of mesoscutum without setae; forewing recurved along posterior margin, nearly parallel-sided below marginal vein, length of marginal setae exceeds width of forewing; petiole much wider than long; ovipositor very short; male genitalia compact and reduced, lacking digiti or a separate aedeagus ( Fig. 3 ).

Biology: Larval parasitoids of various Thripidae (Terebrantia) .

Comments: This distinctive entedonine genus was originally described by Girault (1920 a) in Mymaridae , apparently due to its peculiar forewing. Because females of the species in this genus are quite similar to each other (although details of forewing chaetotaxy, such as the number and position of rows of setae, may be diagnostic) and no females are known for G. rabelaisi sp. n., the key below differentiates their males only.
