Etymology: This species is named after Aleksandr S. Pushkin.

Diagnosis: The new species superficially resembles G. shakespearei , in which the disc of the forewing is more setose in the apical area (beyond venation) in both sexes. In G. pushkini , the forewing disc has a few long setae behind marginal vein sparsely arranged in about 2 irregular rows, but the apical area is completely bare except for one row of setae along anterior margin. In addition, female clava is more elongate in the new species (relatively more compact in G. shakespearei ). Scape of male antenna is moderately swollen (1.6–2.0 x as long as wide), usually slightly more so than in C. rabelaisi sp. n., but considerably and consistently less swollen than in G. shakespearei . Description: Female (holotype and paratype). Colour of head and mesosoma brown to dark brown, metasoma yellow to orange-yellow, appendages pale to light brown.

Antenna ( Fig. 4 ) with scape slender, 3.8–3.9 x as long as wide; F1 very small, subquadrate; F2 a little longer than wide; first claval segment wider than long, second a little longer than wide, third much longer than wide.

Mesosoma about as long as metasoma, almost smooth. Forewing ( Fig. 5 ) about 4.6 x as long as wide; longest marginal setae about 2.2 x maximal forewing width; disc hyaline and with about 2 irregular rows of setae behind venation, otherwise bare except for rows of setae along margins in the broadest part (beyond venation) and several setae just beyond venation. Hind wing about 12 x as long as wide; disc bare except for a row of setae along posterior margin and a few very short setae along anterior margin.

Ovipositor very short, occupying about 1/3 length of gaster, not exserted; ovipositor length/metatibia length ratio about 0.6:1.

Measurements (n=1, holotype). Body: 695. Antenna: scape: 94; pedicel: 52; F1: 14; F2: 27; clava: 75. Forewing: 409/89; longest marginal seta: 197. Hind wing: 355/30; longest marginal seta: 148. Ovipositor: 91.

Male (paratypes). Body length 578–596. Similar to female in every regard except for normal sexually dimorphic features such as the proportions of antennal segments and the genitalia. Antenna with scape only moderately swollen ( Fig. 6 ), 1.6–2.0 x as long as wide (length/width ratio varies quite considerably among the different specimens). Genitalia typical for the genus and resemble those in G. rabelaisi ( Fig. 3 ).

Holotype: Female on slide, labelled: 1. “ SOUTH KOREA: Suwon-si, Seodun-dong , Seoul National University , 37°N: 126°E, 17.ix.2001, J.-W. Kim ”; 2. “Mounted at UCR/ERM by V. V. Berezovskiy 2004 in Canada balsam UCRC”; 3. (red) “ Goetheana pushkini S. Triapitsyn HOLOTYPE ^”[ UCRC].

Paratypes: JAPAN: Ibaraki Pref. (Honshu Island): Tsukuba , 30.viii.1987, “ex. Pseudodendrothrips mori on Mulberry”, 1^ 4ơ on points and 5ơ on 3 slides (3ơ on the same slide) [ CNCI] . REPUBLIC OF KOREA: same data as the holotype, 1ơ on slide [ UCRC] .

Hosts: Pseudodendrothrips mori (Niwa) . It is quite likely that this new taxon is conspecific with the Goetheana species reared in Fukuoka, Kyushu Island, Japan, from the same thrips host ( Takagi 1988). However, it was identified by Dr J. LaSalle as G. shakespearei (Loomans & van Lenteren 1995) . I haven’t seen the voucher specimens pertaining to Takagi’s (1988) study and therefore am unable to confirm that identification. Comments: The holotype female has one antenna missing; flagellum of the other is mounted detached from the body (under the same coverslip).
