Subgenus Lagodechia Negrobov & Tsurikov, 1996 , stat. nov.

Lagodechia Negrobov & Tsurikov [as Zurikov], 1996: 632. — Grichanov et al. 2011b: 23 (diagnosis).

Diagnosis

Describing a new genus, Negrobov & Tsurikov (1996) listed diagnostic characters that can be found in many Diostracus species (e.g., Saigusa 1984, 1995; Saigusa et al. 1997; Yang et al. 2011). The following characters of generic importance were listed in the original description of Lagodechia , but were not obvious on pictures made by O. Selivanova from type material ( Grichanov et al. 2011a, b): antennal scape has dorsal projection; distance between scutellum and 1 st tergum is 3 times as long as scutellum. Negrobov & Tsurikov (1996) also found important differences in the female oviscapt of Lagodechia spinulifera and Diostracus subalpinus ( Negrobov, 1973) . Unfortunately, D. subalpinus (described from the Baikal Lake environs) is the only Diostracus species with illustrated female genitalia. The status of D. subalpinus and D. spinulifer needs further clarification.
