Redescription.

Female. Head. Head smooth with long sparse hairs, in dorsal view longer than wide (19: 15), in lateral view slightly longer than high (19: 18); distinctly nasiform, antennal shelf sharply projecting, anteriorly with small medial projection, and lateral subtriangular projections; upper third of face with a median longitudinal carina, POL:OOL=3:7; eye moderately small, with sparse long hairs, distinctly shorter than postgena (3: 5); eye height much shorter than malar space (15: 22); postgenal cushion well developed; mandibles elongate, beak-like projecting, with serrated tips; antenna much shorter than body length (3: 5), gradually expanded 6-segmented clava; antennal segments a1-12 respectively in following proportions (length: width): 34: 5; 9: 4; 9: 3; 8: 3; 10: 3; 10: 4; 9: 4; 9: 5; 9: 5; 8: 6; 7: 6; 10: 5.

Mesosoma. Mesosoma in dorsal view equal to width of head and much shorter than long (7: 3); cervix long and smooth; pronotum and propleura with dense cushions; mesoscutum smooth, notauli, parapsidal impressions and humeral sulci completely absent; anterior scutellar pit small and deep with longitudinal carinae at bottom, much smaller than remaining scutellar disc (6: 11); scutellar disc rectangular, without lateral and posterior pits; dorsellum with 3 keels, and the median keel distinctly raised; mesosoma in lateral view clearly longer than high (10: 7); lateral part of pronotum smooth; mesopleuron smooth, with sparse hairs, without sternaulus; metapleuron with long dense hairs; median propodeal keel moderately raised, not sharply pointed, not exceeding level of mesoscutum; nucha clearly visible in dorsal view.

Wing. Fore wing with subcostal, marginal and stigmal veins tubular, stigmal vein very short, pointed.

Metasoma. Petiole covered with dense hairs, in dorsal view elongate (10: 20); second tergite (T2) without hairs and median basal notch.

Colour. Body dark brown to blackish brown; antenna yellowish brown with A8-A12 dark brown; legs yellowish brown; tegulae yellowish brown, hyaline; wings hyaline with brown hairs, veins yellowish brown.

Measurements. Head length 0.43 mm, width 0.34 mm; mesosoma length 0.79 mm, width 0.34 mm; metasoma length 1.15 mm; fore wing length 2.63 mm; total body length 2.10-2.37 mm.

Male. Body length 1.80-2.84 mm. Differs from female as follows: Antenna 14-segmented, about 1.6 times the length of the body; flagellum elongate-knotted, with long hairs arranged in a whorl on each node, A8 with a comb of short fine hairs; antennal segments a1-12 respectively in following proportions (length: width): 34: 7; 8: 5; 18: 5; 26: 5; 29: 5; 28: 5; 26: 5; 29: 6; 29: 4; 26: 4; 25: 4; 24: 4; 23: 4; 30: 3; anterior scutellar pit usually almost smooth, some males have the anterior scutellar pit almost smooth to weak or strong longitudinal carinae at bottom.

Variations.

The female of the type specimen has the antenna brown with the apical four segments blackish brown, but South Korean and Japanese female specimens have antenna brown with apical five segments dark brown.

Host.

Unknown.

Distribution.

South Korea (new record), Japan (new record), China (Guangdong, Hainan, Yunan), India (Kerala).

Nomenclature.

Just as for the genus Alareka name above the nomenclatural history of the specific epithet Trichopria keralensis is confused: firstly it was published as a nomen nudum by Rajmohana and Narendran (1999); it was first made available by Rajmohana and Narendran (2000b) but with the multiple original spellings Trichopria keralensis and Alareka keralaensis - the stated etymology is that it was based on the collection locality Kerala, but this does not help as both spellings can be derived from this place name, Alareka keralaensis however appears to be an error since it is used only once. This unsatisfactory situation is resolved as follows; as one of the original authors, Rajmohana (2006) may be considered first reviser ( ICZN 1999, Art. 24.2.4) since she used the spelling Trichopria keralensis , this becomes the correct original spelling, and Alareka keralaensis becomes incorrect and unavailable ( ICZN 1999, Art. 24.2.3).
