Protanypodinae : genera

The subfamily Protanypodinae comprises two basically northern (boreal) genera.The concept was treated previously as a tribe of Diamesinae until raised by Semenchenko et al. (2024), based on molecular and morphological evidence. The key derives from Makarchenko & Endo (2009).

1 Head capsule with dense short simple setae; postoccipital margin on each side with long ventrolateral, posteriorly-directed projections ( Fig. 13C ). Mandible with 5 small inner teeth; seta interna absent ( Fig. 13C ). Broad central mentum without teeth, with 2 pairs of unusual-shaped lateral teeth ( Fig. 13G )......................................... Protanypus Kieffer [lentic, L (subfossil), oriental China (Yunnan, 3000–4000 m.). Holarctic, inc. China, Japan]

1’ Head capsule with many pale, long, simple or terminally split setae; postoccipital margin without or with only short projections ( Fig. 13D ). Mandible with 4 subequal mid-length teeth ( Fig. 13D ), small seta interna present. Mentum with single wedge-shaped median tooth and 3 pairs of lateral teeth ( Fig. 13H )................................. Linevitshia Makarchenko [lotic, L. prima Makarchenko , ♂, oriental China (Zhejiang); L, Shaanxi (Mt. Qinling), Sichuan, Yunnan (Mt. Laojun); Palaearctic, inc. China, Japan]
