Phanerotoma bilinea Lyle, 1924: 101; Zettel, 1987: 364; van Achterberg, 1990: 24-25 (redescription, lectotype designation).

Bracotritoma bilinea ; Shenefelt, 1973: 909.

Phanerotoma gregori Snoflák, 1951: 13; Shenefelt, 1973: 916 (synonymised by Zettel (1987)).

Type material.

Holotype ♀ of P. gregori (MMB); lectotype ♀ of P. bilinea (NHMUK; collected from a Quercus tree).

Additional material.

Yemen (Ar Rujum, Malaise trap; Sana’a, Malaise, light and pitfall traps; Al Kadan, light trap; Ta’izz, light trap; 12 km NW of Manakhah, Malaise trap).

Diagnosis.

Hypopygium of ♀ with spine-like, long and acute narrow triangular protuberance (Figs 40 , 47 ); fourth sternite of ♀ enlarged; inner tooth of mandible 0.4 × apical tooth (Fig. 49 ); vein r of fore wing 0.2-0.4 × as long as vein 3-SR; apical half of hind tibia with large dark brown patch laterally; medially third tergite 1.0-1.2 × longer than second tergite, tergite dark brown medially, rounded laterally and moderately concave medio-posteriorly in dorsal view (Fig. 46 ); ovipositor sheath narrow and only apically with some erect setae. Similar to P. maculata (Wollaston, 1858) from Madeira; but P. bilinea has the third metasomal tergite 1.0-1.2 × as long as the second tergite medially (1.4-1.7 × longer than second tergite in P. maculata ) and its apical half distinctly sculptured and slightly shiny (at least partly smooth and distinctly shiny), middle tibia pale yellow (surroundings of blister dark brown) and vein 2-SR distinctly curved (straight).

Variations.

(Yemen). Length of fore wing of ♀ 2.3-3.0 mm, of ♂ 2.1-2.7 mm; parastigma and vein 1-M of fore wing yellowish, brown to rather dark brown; third metasomal tergite 1.0-1.2 × as long as the second tergite medially; third and fourth antennal segments in ventral view distinctly darker than scapus and only very rarely similar brownish; apical half of hind tibia yellowish ventrally and outer side largely dark brown (but apically yellowish brown).

Biology.

Parasitoid of Argyrotaenia ljungiana (Thunberg, 1797) ( Tortricidae ) and Prays citri (Milliere, 1873) ( Yponomeutidae ).

Distribution.

Austria; Azerbaijan; Belgium; Czech Republic; France; Germany; Greece; Hungary; Japan; Korea; Moldova; Netherlands; Poland; Romania; Russia (including Far East Russia); Slovakia; Spain; Switzerland; Ukraine; United Kingdom; Serbia; *Yemen.
