( Figs 5A , 6 , 11)

Type material. HOLOTYPE: ♀, KENYA: COAST: Taita Hills, Vuria Forest , 3.41428°S 38.29178°E, 2162 m, 28.xii.2011 – 11.i.2012, Malaise trap, just inside indigenous forest, R. Copeland leg. ( NMKE).

Diagnosis. Female with occipital carina incomplete; forewing crossed by dark transverse band; hind wing hyaline.

Description. Female. Fully winged; length 3.4 mm. Head black, except mandible testaceous and clypeus partly testaceous and brown; antenna testaceous; mesosoma black, except disc and lateral regions of pronotum, including pronotal tubercles, testaceous; petiole black; metasoma brown; legs testaceous-whitish, except clubs of femora brown. Antenna clavate; antennal segments in following proportions: 14: 7: 26: 29: 35: 34: 25: 14: 11: 13. Head dull, granulated and reticulate rugose; occipital carina incomplete, only present behind ocellar triangle and on sides of posterior ocelli, laterally not reaching eyes; POL = 8; OL = 3; OOL = 12; OPL = 2; temple absent; greatest breadth of posterior ocellus about as long as OL. Pronotum dull, crossed by one transverse furrow, granulated and transversely striate; posterior tubercle reaching tegula. Scutum dull, completely granulated and slightly reticulate rugose. Notauli complete, posteriorly separated; minimum distance between notauli slightly longer than POL (9: 8). Scutellum shiny, slightly reticulate rugose. Metanotum shiny, unsculptured. Propodeum reticulate rugose. Forewing with one dark transverse band beneath pterostigma; distal part of stigmal vein longer than proximal part (32: 15). Hindwing hyaline, without brown transverse bands Protarsal segments in following proportions: 23: 3: 7: 24: 37. Segment 3 of protarsus produced into hook. Enlarged claw ( Fig. 5A ) with two subapical teeth and one row of 27 lamellae. Segment 5 of protarsus ( Fig. 5A ) with two rows of approximately 38 lamellae; distal apex with approximately six lamellae. Tibial spurs 1/1/2.

Male. Unknown.

Differential diagnosis. With reference to the characters summarized in the above diagnosis, in the Afrotropical Region the new species is similar to Thaumatodryinus dentatus Benoit, 1954 and T. migratorius Benoit, 1954 . The main differences regard the forewing (crossed by one dark transverse band in T. tuukkaraski ; hyaline in T. dentatus and T. migratorius ) and OPL/OL ratio (OPL <OL in T. tuukkaraski ; OPL = OL in T. migratorius ; OPL> OL in T. dentatus ). In addition, the mesosoma of T. migratorius is completely testaceous-reddish, whereas it is partly black in the other two species.

Etymology. This species is named after Tuukka Rask, the acrobatic goaltender for the Finnish National ice hockey team and the Boston Bruins, whose glove hand is as tenacious as the raptorial fore tarsus of this dryinid species.

Hosts. Unknown.

Distribution. Only known from the type locality.
