Male. Cephalic setal warts small, oval; interantennal setal warts absent. Maxillary and labial palps with brushes of setae or sensillae on dorsal face; labial palps with distal segment very short, about 1 / 4 the length of segment 2; maxillary palps 2 - segmented, with distal segment slightly longer than proximal segment and slightly shorter than eye diameter.

Segment IX, in lateral view, expanded anteriorly into rounded lobe, anteroventral margin shallowly concave; horizontal lateral apodeme present; dorsal margin nearly straight; inner margin wide, V-shaped in dorsal view and shallowly concave in ventral view; in ventral view, posterior margin forms 2 short, wide lobes. Segment X weakly up-curving, narrowest at apex; with 4 megasetae confined to truncate apex; lateral processes absent. Superior appendage moderately long, club-shaped, oriented posteroventrally. Gonocoxite primary branch uniformly broad in lateral view, weakly sigmoid; secondary branch short, straight, tube-shaped in ventral view, with 2 posteriorly oriented apical setae; gonocoxite basal branch absent; gonocoxite basal plate nearly reaching anterior margin of segment IX in lateral view; anterior part very slender, nearly equally broad along its length; in ventral view, wider than in lateral view, parallel-sided and apically truncate. Phallus apparently with internal processes in addition to phallic sclerite; in lateral view, nearly parallel-shaped and weakly curving ventrally along its length; in ventral view, cigar-shaped; central part nearly 2 x wider than anterior and posterior parts.	en	Johanson, Kjell Arne, Malm, Tobias (2007): Three new Helicopsyche from Laos (Trichoptera: Helicopsychidae).

03C4D450FFA06A102FD1FE1DBF9336DB.taxon	description	Figs. 4, 21 – 30 Helicopsyche pathoumthongi, new species, has forewing R 5 densely covered by blackish rod-shaped setae (Fig. 4). The species is unique in the genitalia by the nearly uniformly wide, sickle-shaped primary branch of the gonocoxite, the presence of a secondary branch of the gonocoxite that is shorter than the width of the dorsal branch, and by the long basal branches that curve slightly mediad and bear 2 distal and 2 median setae. Segment X is club shaped in lateral view, with very slender lateral processes running parallel with the lateral margins. Also H. antikleia has long, slender processes on segment X, but in H. antikleia only the anterior part of the processes are attached to segment X, while in H. pathoumthongi the processes are attached to segment along their length. Male. Cephalic setal warts small, oval; interantennal setal warts absent. Maxillary and labial palps with brushes of sensillae on dorsal face of segments; labial palp distal segment very small, about 1 / 4 as long as 2 nd segment; maxillary palp distal segment slightly longer than basal segment, shorter than eye diameter. Antennal scape length equal to eye diameter. Tibial spurs 1, 2, 4. Forewing brownish grey with characteristic pattern of small, pale spots scattered over wing surface (Fig. 4), and with short, dark setae along R 5, length 4.4 mm; hind wing length 3.3 mm, with 14 hamuli; wing venation as in Fig. 23. Male abdomen and genitalia (Figs. 24 – 30). Sternal process VI short, oriented posteroventrally; in ventral view narrowing towards midlength, apex slightly club-shaped, densely covered by small spines. Segment IX, in lateral view, strongly expanded anteriorly, anteroventral margin nearly straight except concave near posterior corner; with sub-marginal anterior apodeme and horizontal lateral apodeme; dorsal margin nearly straight; inner margin V-shaped in dorsal view and U-shaped in ventral view; posterior margin forms 2 short, wide lobes in ventral view. Segment X straight, narrowest at mid-length; with 9 megasetae confined to clubshaped apex; 1 pair of lateral, tube-shaped processes originating from basal part of segment X, running posteriorly and attached to central segment X forming a ridge, distal-most part separated from segment X. Superior appendage long, tubular, slightly bent upwards and club-shaped at apex. Gonocoxite primary branch nearly uniformly wide in lateral view, forming a half-circle; secondary branch slightly tapering towards apex, slightly curving ventrally in lateral view and medially in ventral view, with 1 basal, 2 median, and 1 apical setae; gonocoxite basal branch short, truncated distally, with few long setae oriented posteriorly; gonocoxite basal plate long, exceeding segment IX in lateral view, anterior part nearly equally broad; in ventral view, anterior part needle-shaped. Phallus without additional sclerites, curved posteriorly at 1 / 3 its length and ventrally at 2 / 3 its length; about equally wide along its length in lateral view; in ventral view, anterior half about as wide as in lateral view; distal half about 3 x broader than anterior part.	en	Johanson, Kjell Arne, Malm, Tobias (2007): Three new Helicopsyche from Laos (Trichoptera: Helicopsychidae).
