Re-description of Protonemura auberti View in CoL
Morphological diagnosis. A medium-sized Protonemura species. Body length of males 5–7 mm, females 7–9 mm. Males and females macropterous. General color light reddish-brown; head dark; antennae and legs light brown-colored. Forewings smoky brown. Cervical gills short, without pre-apical constriction ( Fig. 9 View FIGURES 9–12 ). Sclerotized base of the median lobe of the paraprocts of adult males piriform; sclerotized stem arising like a tapering extension from the inner upper edge of the sclerotized median lobe ( Figs. 5–7 View FIGURES 5–8 ).
Males ( Figs. 1–8 View FIGURES 1–4 View FIGURES 5–8 ). Tergites 8 and 7 with several rows of strong spines on each side of posterior margin, medially interrupted; tergite 6 with two to four smaller spines in one row on each side ( Fig. 4 View FIGURES 1–4 ). Hypoproct terminated by a finger-shaped expansion ( Fig. 6 View FIGURES 5–8 ). Ventral vesicle ovoid-shaped ( Figs. 5, 6 View FIGURES 5–8 ). Inner lobe of paraprocts hidden by hypoproct. In ventral and lateral view, sclerotized base of median lobe of the paraprocts reniform or piriform ( Figs. 5–7 View FIGURES 5–8 ). Sclerotized stem arising like a tapering extension from the inner posterior edge of the sclerotized median lobe ( Figs. 5–7 View FIGURES 5–8 ). Sclerotized stem thick at its base, progressively thinning out at its apex ( Figs. 5–7 View FIGURES 5–8 ). Sclerotized stem long and regularly curved, largely extending over the membranous field ( Figs. 5–7 View FIGURES 5–8 ), and with one or two, rarely three, apical spines ( Fig. 1 View FIGURES 1–4 ). Membranous field often with a dark thorn. Outer lobe sclerite (OLS) with a large median part ( Fig. 8 View FIGURES 5–8 ) from which three branches originate: a narrow basal branch turning around the cercus (= OLS1; Fig. 8 View FIGURES 5–8 ; cf. Fig. 7 View FIGURES 5–8 ), a second, short and thick branch (= OLS2; Fig. 8 View FIGURES 5–8 ) located between the cercus and the membranous field of the median lobe, and finally a short and small, sometimes invisible without the cercus removed, sclerite that arises from the second branch (= OLS3; Fig. 8 View FIGURES 5–8 ; Kis 1974, fig. 99C). Epiproct with a median widening in lateral view ( Figs. 1, 2 View FIGURES 1–4 ). Tip of epiproct short and strongly bent upwards, with a wide gap between the tip and the upper median part of the epiproct ( Figs. 1, 2 View FIGURES 1–4 ; Illies 1955, fig. 29C). Tip of epiproct with a small, transparent, globulous extension, flanked by two short and thick dark thorns on each side, visible only by transparency through the cuticle ( Fig. 2 View FIGURES 1–4 ). Tip of epiproct with a dark oval-shaped sclerite, in dorsal view ( Fig. 3 View FIGURES 1–4 ). Ventral sclerite of the epiproct with a median bulge bearing a row of spines pointing backward and not extending beyond the tip of the ventral sclerite.
Females ( Figs. 10–12 View FIGURES 9–12 ). Pregenital plate of sternite 7 brightened, triangle-shaped, with posterior margin not extending over sternite 8 ( Figs. 10, 12 View FIGURES 9–12 ). Subgenital plate wide, with a ribbon-shaped sclerotized band, slightly bulging out in its median part and blunt at its edges ( Figs. 10, 12 View FIGURES 9–12 ). Vaginal lobes of the subgenital plate large and bulbiform, partly covering sternite 9 and extending nearly to the edge of sternite 8 ( Figs. 10, 12 View FIGURES 9–12 ). Vaginal lobes medially separated by a deep V-shaped notch ( Figs. 10, 12 View FIGURES 9–12 ). In lateral view, genital plate slightly bent downwards, and vaginal lobes protruding ventrally ( Fig. 11 View FIGURES 9–12 ).
