P. stenophylla with hypodermal marking on anterior side of femur usually like a band, wider than long; scattered short, fine, simple setae on surface of abdominal terga; paracercus with ~ 15 segments (Kaltenbach et al. 2025: figs 132 a, b, 135 d). However, male imagos are clearly different: P. longabranchias sp. nov. has pale brown turbinate eyes (Fig. 26 a, b), whereas P. stenophylla has dull-red turbinate eyes (Kaltenbach et al. 2025: fig. 137 a, d). The eggs of both species are identical (Fig. 28 a – d; Kaltenbach et al. 2025: fig. 138 a).</p><p>Biological aspects.</p><p>The species is known from two watercourses in southern Batanta: Kalijakut (Fig. 29 d (type locality), f) and Tanjung Lampu Rivers at elevations from 182– 420 m.
