( Fig. 42 )

Mesocapnia Raušer, 1968 — Raušer 1968: 337. (original description, type species Mesocapnia silvatica Raušer, 1968 ); Zhiltzova 2003: 375. (revision of the Palaearctic species).

Capnia projecta species complex sensu Baumann & Gaufin 1970 — Baumann & Gaufin 1970: 435. (revision of the Nearctic species).

Diagnosis. Male epiproct: B-scl small, fused with or divided from Ep-scl; Lb-scl small, fused with Ep-scl; Ep-scl entire both ventrally and laterally, caudal setae present; I-scl and Ec absent. Male Pp: apical part long and narrow; Fp long and medium wide, divided from Rp. Male Sg: fused with St 9 and Tg 9, vesicle absent. Female Sg: rounded or pointed, entire; small lateral sclerites present. Male tergites: process lacking. Ventral thoracic sclerites: MPrs elliptical or triangular, MeFs triangular, MeFsp separated from MePfs; PFs and PBs separated or weakly fused. Macropterous wings: forewing A1 beyond a and R1 before r curved.

Species included. 3 valid species from the East Palaearctic, 1 from the Transpalaearctic and the West Nearctic, 14 from the West Nearctic and 1 from the East Nearctic ( DeWalt et al. 2014, Zhiltzova 2003); 13 of the species examined (see Appendix 1).
