M.B. Lara and A. Bashkuev 2020 | If one would follow the formal criteria introduced by Novokshonov (1997a), such as the number of branches in radial and medial sectors, Potrerillopanorpa gen. nov. could be placed in the subfamily
Agetopanorpinae Carpenter, 1930 of Permochoristidae. On the other hand, pectinately branched RS1 + 2 (notwithstanding the fork on RS4) evidences for its affinity with the Permian–Triassic family Parachoristidae Handlirsch, 1937 or Triassic–Cretaceous Orthophlebiidae Handlirsch, 1906, which are considered basal members of the crown-group Mecoptera – the Panorpoidea (sensu Novokshonov, 2002; or Panorpomorpha sensu Willmann, 1989, regardless of the position of Raptipedia). Both these families lack precise diagnoses, being highly heterogeneous and apparently paraphyletic (Willmann 1989; Soszyńska- Maj et al. 2016; Soszyńska-Maj et al. 2018). According to Novokshonov (1997a; 2001), the distinction between Parachoristidae and Orthophlebiidae (s.l.) is ill-defined and can be summarized as follows: wings of Parachoristidae usually (not always) are characterized by 1) rather expanded costal and subcostal spaces (vs. more or less narrow in Orthophlebiidae); 2) Sc with long oblique branch Sc2 (vs. Sc2 short if present); 3) M has more branches (5 – 8), often with additional terminal forks (in Orthophlebiidae, M with 5 veins, less often with 6, never with additional terminal forks); 4) well-developed cubito-median Y-vein with distinct M5 (the upper arm of Y-vein) (the Y-vein is not or ill-developed in Orthophlebiidae and M5 usually is short and crossvein-like, often weakly sclerotized). In the subfamily Neoparachoristinae, however, CuA and M fused for some distance and Y-vein is not developed at all. Each of these characters is quite variably developed in Parachoristidae and partially overlapping with Orthophlebiidae. |
