Source: Epiproct And Dorsal Process Structure In The Allocapnia Forbesi Frison, Allocapnia Pygmaea (Burmeister), And Allocapnia Rickeri Frison Species Groups (Plecoptera: Capniidae), And Inclusion Of Allocapnia Minima (Newport) In A New Species Group

Male epiproct. Apical segment of upper limb ca. 210 µm long, bearing a pair of basolateral ear-like projections and a dense median patch of wave-like spikes (Figs. 19 - 22). Median spike patch ca. 200 µm long and separated along entire length by narrow groove (Fig. 20), ear-like projections without spikes. Apical segment ca. 161 µm wide across ear-like projections and narrowed to ca. 47 µm at apex. Basal segment of upper limb ca. 344 µm long and ca. 78 µm wide at mid-length; apical third of basal segment bearing a sparse patch of setae; median field of basal half with wide groove (Fig. 19). Lower limb ca. 172 µm wide proximal to apical spoon. Male tergal process. Prominent raised structures on abdominal terga 7 and 8 (Figs. 22 - 24). Process of tergum 7 conical, apex without scale-like structures (Fig. 23); process of tergum 8 thin in lateral aspect (Fig. 22), dorsal surface truncate, or slightly concave, and bearing a pair of dorsolateral patches of scale-like structures (Fig. 24). Width of tergum 8 process ca. 100 µm.
