Diagnosis. The shape of the tenth abdominal tergite of H. kondiu sp. nov. being divided into two long apical lobes with obtuse tip resembles the situation in H. wau sp. nov. and differs from that of H. simbai sp. nov., while the shape of the male cerci is similar to those in H. simbai but markedly different from those in H. wau . It differs from both by the shape of the cerci that have the disc shaped projection running around the tip of the cercus while in H. wau and in H. simbai it projects only from the dorsal surface. The internal process of the male cerci is similar in H. kondiu and H. simbai , but in H. kondiu the short acute apical lobes are shorter than in H. simbai . The titillators of H. kondiu also resemble more those in H. simbai than the strongly modified shape in H. wau . The titillators of H. kondiu and H. simbai are of similar basic shape, but in H. kondiu the apical area of the distal branches is completely separated from the more basal area while in H. simbai it is still connected to but moveable against that area. The female of H. kondiu has the subgenital plate of similar general outline as in H. simbai ; it differs by the margins of the subgenital plate being angular and the stout basal and lateral areas being thicker and wider and the compressed and thin central area narrower than in H. simbai .

Description. Coloration of face uniformly pale, of general color or laterally indistinctly darkened; antennal scrobae partly black or of same color as face; mandibles pale, only the in situ hidden tips black ( Fig. 4E View FIGURE 4 ). Tegmen yellowish semi-transparent with dark cells especially in anterior area; radius in more than basal half brown ( Fig. 20B View FIGURE 20 ). Coloration of abdominal tergites varies between specimens from light yellowish brown to dark brown or almost black. Femora with the following number of spines on ventral margins: (1) a 5–8, p 5–8; (2) a 5–8, p 2–4; (3) a 10–13, p 10–14 (n=5).

Male. Stridulatory file on underside of left tegmen diagonal length 1.35–1.56 mm, with 82–93 teeth that are at both ends very narrow (19–30 apical, 9–14 basal teeth); in central 1 mm of file with 49–52 teeth, of which largest 21.5–22.0 teeth in central 0,5 mm ( Figs 19E–F View FIGURE 19 ). Tenth abdominal tergite in less than basal half with sub-parallel, down-curved lateral areas, afterward with approaching lateral margins and deeply incised from apical margin forming a pair of triangular lobes with obtuse tips; bottom of apical incision obtusely rounded ( Figs 9D–E View FIGURE 9 ). Epiproct roughly triangular with medial furrow and rounded angles. Cercus rounded elongate, in apical area curved mediad into a process with flattened dorsal surface and slightly approaching margins; the process terminates into two short cones with acute tips, ventro-apical cone little longer than dorso-proximal cone; at end of cercus stem with a semidisc-shaped projection around dorsal and apical margins with slightly concave internal and convex external surface ( Figs 9D–E View FIGURE 9 ). Subgenital plate in lateral view curved throughout; in basal area elevated and provided with an oval swelling that in situ can be hidden from ninth tergite, afterward with dorsal rim and a lateral furrow in little more than basal half; ventral surface from base with a large triangular and membranous incision; lateral margins little swollen and with a shallow medial furrow; in about apical third deep roundly incised and upcurved, lateral margins little approaching towards tip; styli short, inserted at underside of the narrow apical branches of the subgenital plate ( Fig. 11I View FIGURE 11 ). Titillators at very base shortly curved distad, otherwise in basal area subfused and parallel, at end becoming darker and divide into proximal and distal branches; proximal branches curved proximad and ventrad and end into rounded tips that are covered by a common hyaline membrane; distal branches curved dorso-distad and end into obtuse tips; on ventro-apical side of these obtuse tips with a pair of broad, flattened and markedly curved dark sclerites that are connected to the titillator stem only by membrane and end into a compressed, nearly disc shaped apex with serrulate margin ( Fig. 16D–I View FIGURE 16 ). A pair of large, elongate, three-edged lateral sclerites with wavy margins is also present.

Female. Subgenital plate at base with long dorso-lateral projections with wide obtuse end; hind margin of these projections from about mid-length widened into an oblique connection with the lateral rims of ventral surface; ventral surface with basal margin little concave, followed behind by an indistinctly outlined, transverse oval groove; stiffened lateral margins long, running parallel to each other and are narrowed toward subacute tips; about half of the area between the stout margins connected by a thin and little caved-in membranous surface ( Figs 6G–H View FIGURE 6 , 7D View FIGURE 7 ). Ovipositor little shorter than body; behind basal constriction dorsal margin convex, markedly but not very strongly elevated in middle and narrowing again towards sub-obtuse tip. ( Figs 2E View FIGURE 2 ).

Etymology. The new species is named after the type locality, noun in apposition.
