Paracapnia Hanson, 1946
(Fig. 45)
Paracapnia Hanson, 1946 — Hanson 1946: 225. (original description, type species Paracapnia curvata Hanson, 1946 = Chloroperla opis Newman, 1839); Zhiltzova 2003: 385. (revision of the Palaearctic species); Stark & Baumann 2004: 97. (revision of the Nearctic species).
Diagnosis. Male epiproct: B-scl vestigial or large, divided from Ep-scl; Lb-scl large, hardly divided from Ep-scl; Ep-scl entire both ventrally and laterally, caudal setae absent; I-scl absent, Ec present. Male Pp: apical part long and narrow; Fp short or medium long and wide, divided from Rp. Male Sg: fused with St 9 and Tg 9, vesicle absent. Female Sg: rounded, entire; inner and lateral sclerites absent. Male tergites: process lacking. Ventral thoracic sclerites: MPrs triangular or elliptical, MeFs transverse or triangular, MeFsp fused with or separated from MePfs; MeFsa reduced or distinct. Macropterous wings: forewing A1 beyond a straight, R1 before r curved.
Species included. 1 valid species from the East Nearctic, 1 from the Transnearctic, 5 from the West Nearctic and 4 from the East Palaearctic (DeWalt et al. 2014); 7 of these species examined (see Appendix 1).
Remarks. Several species presently placed in this genus are different from the type species, in both the thoracic ventral sclerites and the male terminalia (Tables 1, 3–4). Paracapnia boris Stark & Baumann, 2004, P. humbolta Baumann & Lee, 2007 and P. baumanni Kondratieff & Lee, 2010 differences of the ventral sclerites were already noted in their original descriptions. In addition, these species differ also with having a large basal sclerite of the epiproct (instead of vestigial) and a longer fusion plate.
