Diagnosis. This species is characterised by the four distinct dark-brown bands on the dorsum of the head and its vertex dark brown; and by the genitalia stouter than the congeners and with the ventral process of the pseudepiphallic paramere short, slightly curved inwards and not surpassing its pseudepiphallic lophi; and the ectophallic fold very slender with the anterior and posterior margins straight and converging.
Etymology. The species name refers to the species being found to inhabit the highlands “among the clouds” in Sabah; nimbus = cloud in Latin.
Description. Smaller and lighter in colouration than the preceding species, yellow brown in general ( Figs 1C, 1D View FIGURE 1 ). Head dorsum yellow brown, with four distinct dark-brown bands and vertex dark brown ( Fig. 2B View FIGURE 2 ). Face rounded ( Fig. 2D View FIGURE 2 ). Antennae inserted at level midpoint of eye in anterior view ( Fig. 2D View FIGURE 2 ). Vertex sloping anteriorly ( Fig. 2F View FIGURE 2 ) Eyes projected anteriorly, slightly taller than wide ( Fig. 2F View FIGURE 2 ); median ocellus transverse, smaller than lateral ocelli; lateral ocelli oblong, whitish ( Fig. 2D View FIGURE 2 ). Maxillary palpi brown; with apical segment elongated-triangular, distinctly longer than subapical and third segments; with subapical segment cylindrical and expanded slightly distally, somewhat similar length as apical and third segments; third segment cylindrical ( Fig. 2F View FIGURE 2 ). Pronotal disc brown about 1.7 times as wide as long, widening posteriorly (posterior margin about 1.6 times as wide as anterior margin); anterior margin of disc broadly concave; posterior margin of disc slightly convex ( Fig. 2B View FIGURE 2 ). Pronotal lateral lobe 1.1 times as long as high ( Fig. 2F View FIGURE 2 ). TI slightly swollen; with inner and outer tympana open and having oval tympanal membrane; legs generally pale brown.
Male. FW yellow brown and slenderer; about 3.1 times as long as broad ( Fig. 2H View FIGURE 2 ); covering abdomen. Venation ( Fig. 2H View FIGURE 2 ): 1A vein transverse, faintly sinusoidal; diagonal substraight, with two distinct and one shorter less-distinct oblique veins in harp area; posterior two oblique veins faintly curved and parallel, join at base near 1A, anterior most vein distinctly shorter and running nearly perpendicular to 1A. Mirror about 1.4 times as long as wide, dividing vein strongly curved at basal end. Lateral field around 10 branches on Sc ( Fig. 1D View FIGURE 1 ). Apical field 0.14 times as long as FWL ( Fig. 2H View FIGURE 2 ). Hind wings clearly surpassing FWs but not cerci.
♁ genitalia ( Figs 3D–F View FIGURE 3 ). Pseudepiphallus [epiphallus] typical of genus, stouter than preceding species. Posterior end of pseudepiphallus [epiphallus] produced into two stout tongued-shaped pseudepiphallic lophi [posterolateral epiphallic lobe] with apices obtuse; between these lophi triangularly emarginated. These lophi, in profile, flattened and having fine setae on dorsal surface. Pseudepiphallic paramere [ectoparamere] with ventral process short, slightly curved inwards and not surpassing pseudepiphallic lophi; with external margin more sclerotized. In profile, ventral process pointing slightly ventrad. Dorsal process of pseudepiphallic paramere weakly sclerotized and not surpassing pseudepiphallic lophi; apices acute. Ectophallic fold [rachis] in profile very slender and tapering into very acute apex, with anterior and posterior margins straight and converging.
Measurements (3♁, in mm). See Table 1 View TABLE 1 .
