description: Cheumatopsyche pali Oláh & Johanson, new species   
Fig. 20–23  
 The shape of segment IX and the extremely elongated preanal appendages of this species makes it clearly related to C. vala Malicky. Cheumatopsyche pali is separated from C. vala in the shape of both the coxopodites and harpagones; in addition, segment IX is shorter and not so rounded anteriorly.   
Male. Body and wings brown with brown pubescence. Maxillary palp segment I shortest, segment II longer, segments III and IV equally long, segment V as long as segments I–IV together. Head dorsum dark brownish, with 7 visible, slightly paler warts. Swollen setal wart on proepisternum absent. Male protarsal claws asymmetrical, laterally flanked by setal bundle. Forewing length 7.8 mm, hind wing length 5.8 mm. Distance between forewing crossvein m-cu1 and cu shorter than length of crossvein m-cu, or crossveins tangent. Hind wing fork I absent.  
Male genitalia. Abdominal segment IX fused annularly; tergum and sternum short (Fig. 20); anterolateral margins of segment IX almost uniformly convex in lateral view, with upper halfs slightly flatter (Fig. 20); apical lobe on posterolateral margins well developed, located above base of coxopodites; spine row on posterolateral margins of segment IX interrupted below tergal corners, well developed on apical lobes. Margin of intersegmental depression between segment IX and segment X right-angled (Fig. 20). Segment X nearly quadrangular in lateral view (Fig. 20), clearly bilobed in dorsal view (Fig. 21); apex of setaless mesocaudal lobe narrow, bluntly triangular in dorsal view (Fig. 21), apicoventral setal lobes each forming almost straight, finger-like processes in lateral and dorsal view; preanal appendages forming long setose lobes, broad in dorsal view, slender in lateral view. Transverse and longitudinal sutures present. Coxopodites exceeding beyond apex of segment X; in lateral view, straight, with dilating apices (Fig. 20); in ventral view (Fig. 22), slightly curving mesad near apices. Harpagones slender, curving dorsad and mesad, base wide. Phallotheca (Fig. 23) with straight dorsum, except slightly concave near apex; sclerotised endothecal process ovoid, phallotremal sclerites tall in lateral view.
