Murányi, Dávid, Gamboa, Maribet & Orci, Kirill Márk, 2014, Zwicknia gen. n., a new genus for the Capnia bifrons species group, with descriptions of three new species based on morphology, drumming signals and molecular genetics, and a synopsis of the West Palaearctic and Nearctic genera of Capniidae (Plecoptera), Zootaxa 3812 (1), pp. 1-82 : 22-24

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.
