It is most similar to <i>H. curvata</i> <b>sp. nov.</b> that lives at the Mamberamo River. <i>H. pallida</i> <b>sp. nov.</b> differs from the latter by the shape of the male cerci that have the apical area on internal side excavated and merging at end into a compressed but wide internal process that terminates into two acute tips while in <i>H. curvata</i> the male cerci have a compressed triangular internal process from sub-apical area that terminates into a single acute tip. The male titillators are similar in both species but in <i>H. pallida</i> they have the apical area narrow oval and the narrow, curved end longer, while in <i>H. curvata</i> the apical area at ventral margin is semi-circularly projecting and the narrowly curved end shorter. The female subgenital plate of <i>H. pallida</i> has the lateral margins strongly upcurved and the apical margin truncate with a pair of up-bent acute spine-like projections. This resembles the situation in <i>H. pedala</i> <b>sp. nov.</b> However, in the latter species, the apical margin is also upcurved and the apical spine-like projections are markedly stouter and shorter. There is some variation in the shape of the female subgenital plate, documented in Figs 5H–L. <b>Description.</b> Coloration of face uniformly pale, of general color; mandibles black, in some specimens with little distinct light spots in baso-external and apical areas. Femora with the following number of spines on ventral margins: (1) a 4–8, p 7–8; (2) a 6–8, p 3–4; (3) a 11–16, p 14–19 (n=9). Male. Stridulatory file of holotype on underside of left tegmen 2.33 mm long, with a distinct step in distal area; with 72 teeth, of which 8 narrow teeth at base, 38 in main part of file, 6 at step, 12 clearly separated at end, and 8 of decreasing size at end (Fig. 17C). Stridulatory file (4 other specimens): 2.35–2.57 mm long with 67–79 teeth (mean 74 teeth), of which in curved narrow basal area 9–11 teeth at 0.31–0.35 mm, in middle of file with 32–34 large teeth at 1.40–1.51 mm, at step with 4–7 teeth at 0.13–0.19 mm, and in narrow apical area with 21–28 teeth at 0.39–0.64 mm (Fig. 18B). Tenth abdominal tergite transverse, in midline furrowed, from apical margin with a narrow and deep incision with setose margins, lateral margins roughly parallel (Fig. 17A). Supra-anal plate narrow, elongate, little widening toward subtruncate or slightly concave apical margin, which carries at both apical angles a small tubercle. Cerci in about basal half roughly cylindrical with slightly flattened internal surface; afterward with an obtuse dorsal carina that outlines the strongly excavated internal surface and is curved onto proximal margin of the wide apical internal process; the process divides in apical area into a proximal, narrow cylindrical and a distal, at base flattened branch, both with an acute spine at tip; the end of the cercus stem forms a short obtuse bump that hardly projects behind apical margin of the internal process (Figs 8F). Subgenital plate at base with a roughly triangular membranous area; in about basal two thirds wide with convex dorsal lateral margins that are approaching posteriorly into the nearly parallel-sided apical area; apical margin little triangularly incised followed by a short narrow slit in middle, lateral margins in apical area forming obtuse rounded carinae which are at end little project behind disc (Fig. 11B); on dorsal side of subgenital plate with a small disc shaped elevation around the projecting area of the rounded carinae; styli short (Fig. 8G–H). Titillators moderately widened at base and shortly curved ventro-apicad, afterward ascending and simply band-shaped, in little more than apical half curved ventro-apicad and in roughly apical third widened to a long-oval plate that is at end little narrowed and in-curved, with obtuse tip; phallus also with a pair of elongate lateral sclerites and a pair of small rounded sclerites on top of the titillators (Figs 13A–F, 17B). Female. Subgenital plate wide at base with converging lateral margins and elevated disc; disc in basal half provided with a narrow medial carina in midline; surface of disc in dried specimens slightly concave; apical margin of disc truncate, straight, and provided at both lateral angles with a rather long, obliquely up-bent spine-like process with subacute tip (Figs 5H–L). Ovipositor about one and a half time as long as body; behind basal constriction straight with dorsal valves in basal half faintly convex (Fig. 1D). Measurements (3 males, 7 females).—Body w/wings: male 42–47, female 48–53; body w/o wings: male 30–37, female 39–43; pronotum: male 8.8–9.5, female 9–10; tegmen: male 31.5–34, female 36–39; hind femur: male 22.5– 25.0, female 25–28; antenna: male 90–110, female 95–130; ovipositor length: female 57–67; ovipositor height: female 2.5–2.7 mm. <b>Etymology.</b> The new species is named for its uniform pale coloration, from Latin <i>pallidus, pallida</i> = pale.
