Capnura Banks, 1900

( Fig. 43 )

Capnura Banks, 1900 — Banks 1900: 245. (original description, type species Capnura venosa Banks, 1900 ); Nelson & Baumann 1987: 3. (stat. rev., revision).

Capnia Pictet, 1841 — Hanson 1946: 229. (synonymy of Capnura Banks, 1900 with Capnia Pictet, 1841 ).

Diagnosis. Male epiproct: B-scl lacking, developed into small to large Ll attached to Ep-scl; Lb-scl large, divided from Ep-scl; Ep-scl entire both ventrally and laterally, caudal setae vestigial or present; I-scl and Ec absent. Male Pp: apical part medium long and tapering; Fp long and narrow, divided from Rp. Male Sg: fused with St 9 but divided from Tg 9, vesicle lacking. Female Sg: incised or pointed, lateral sides with different color than medial part; inner and lateral sclerites absent. Male tergites: Tg 7 (occasionally 6–8) with process. Ventral thoracic sclerites: MPrs and MeFs triangular, MeFsp separated from MePfs. Macropterous wings: forewing A1 beyond a and R1 before r curved.

Species included. 6 valid species from the West Nearctic and 1 from the East Nearctic ( DeWalt et al. 2014); all 7 of these species examined (see Appendix 1).
