Syntypes (at least 2; Hallerman 1998:211): NMW 13247 (Tiedemann & Häupl 1980:8; Tiedemann et al. 1994:12; photographed in Vetter 2002:93 and 2011:145 and Stuckas et al. 2013:3; sampled genetically by Stuckas et al. 2013 and Kindler et al. 2016) and ZMH 992–993 (photographed in Bour 2013a:37 and Bour & Gerlach 2008:1 [993 only]; listed in Bour 1983:353 as 982–983; repeated by Iverson 1992:67); NMW 13247 erroneously listed as “type” by Broadley (1981b:655) and as lectotype by Bour (1983:353) and Bour & Gerlach (2008:1), who credited Broadley with the lectotype designation. Wallerman (1998:211) recorded only a single ZMH specimen (993); whereas Grünwaldt (1980:17) listed ZMH 982 as P. sinuatus, and 983 and 993 as P. subniger .
