Type material. ZIN: Holotype Ƥ: “Shaowu, Fukien, China, 10: XI.1945. M.Chao”, “from Psyllidae on firmian” (in Russian), “ Holotypus Dilyta longinqua V. Belizin det.” (red), “ Holotype Dilyta longinqua sp. n. Paretas-Martínez & Pujade-Villar” (red); paratypes 2Ƥ 23: same locality data than the holotype, “ Paratypus Dilyta aleevae m V. Belizin det.” (red), “ Paratype Dilyta longinqua sp. n. Paretas-Martínez & Pujade-Villar” (red).

Diagnosis. Similar to D. japonica n. sp., D. sinica n. sp. and D. subclavata in having distal area of metasoma punctate. Differs from these in proportions of antennal segments (see key). Differs from D. aleevae n. sp. and D. rathmanae these having distal area of metasoma smooth without punctures.

Description. Length: Female: 1.4–1.5 mm. Male: 1.3–1.8 mm.

Colour. Head, mesosoma and metasoma dark brown. Antennae and legs yellow or dark yellow with the apical part of antennae slightly brown.

Antennae (figs. 3D, 4D): Female. F1 subequal to pedicel or slightly longer, F2 shorter than F3, F3 shorter than F4, F4 shorter than F5, F1 subequal to F5; F6–F11 wider than previous segments, antenna slightly clavate from F6; sensilla beginning on F6. Male. F1 subequal to pedicel and slightly arched, F2 shorter than F1 and F3, F3 subequal to F1; F3–F12 wider than previous segments, antenna slightly clavate from F3; sensilla beginning on F3.

Metasoma: Distal half with a punctate area.

Etymology. We want to respect the specific name handwritten by V. Belizin, which was never published. We do not know its derivation.

Biology. According to the holotype label, the host is a Psyllidae on the plant Firmiana simplex (Sterculiaceae) (L.f.).
