Cheumatopsyche barakambra Oláh & Johanson , new species

Fig. 291–294

This dark brownish animal has short apicoventral setose lobes and triangular dorsocaudal, smooth plate, and belongs to the C. capitella species cluster ( Martynov 1934). Cheumatopsyche barakambra , new species, has triangular apical lobe and shifted to mid-height of segment IX; continuous fused rim-like dorsolateral spiny lobes, not separated and triangular; a mesocaudal plate on segment X being bifid triangular, smooth; and slen- der, sinuate harpagones.

Male. Body dark brown, with dense brown pubescence, mainly on legs. Maxillary palp formula I-(III, IV)-II-V, segment V as long as sum of segments I–IV. Head dorsum dark brown, with 9 dark brown warts. Swollen setal wart absent on proepisternum. Setal surface present on precoxale. Pretarsal claws asymmetrical, laterally flanked by setal bundle. Mid- and hind-leg claws asymmetrical.

Wings. Forewing membrane evenly brown, with slightly darker veins and few small, faintly scattered maculae, nearly invisible in dry animal. Forewing crossveins m-cu and cu almost tangential in oblique line. Cu2 and A1 running separately before costa. Hind wing Sc and R meeting about at crossvein r. Fork 1 absent. Forewing length 7.0 mm.

Male genitalia. Abdominal segment IX fused annularly ( Fig. 291); tergum half as long as sternum. Anterior margins of segment IX regularly bow-shaped; dorsally sinuate in lateral aspect ( Fig. 291). Apical lobe on posterolateral margins triangular, locted at mid-height of segment IX ( Fig. 291). Spine row on posterior margins of segment IX intermittent and heterogeneous. Spines on dorsolateral spiny lobes 3 times longer than spines on apical lobes; in dorsal view, dorsolateral spiny lobes fusing into continuous rim-like plate with tiny mesoapical triangular ( Fig. 292). Intersegmental step between segments IX and X absent. Segment X quadrangular in lateral and dorsal view ( Fig. 291, 292); quadrangular shape in dorsal view emphasized by presence of straight apicoventral setose lobes; segment X trilobed in dorsal aspect. Dorsal interlobular gap wide, partially filled by bifid, triangular, smooth mesocaudal lobes. Suture system well developed on both sides, broad, transverse, crossing segment X obliquely, reaching mid-length at dorsal margin. Longitudinal sutures broad, apparently forming continuation of apicoventral setose lobe on each side, crossing transverse sutures forming a X. Smooth mesocaudal plate forming bifid, triangular lobe. Apicoventral setose lobes short, parallel-sided in lateral and dorsal view ( Fig. 291, 292), curving dorsad; in dorsal view ( Fig. 292) straight, obliquely cut, slightly producing laterad at apices. Lateral setose areas (superior or preanal appendages) form- ing small, elevated, elongated setal warts, located centrally on distal half on both sides, surrounded by transverse and longitudinal sutures. Coxopodites strongly exceeding apex of segment X, forming double sinuate, slightly S-shaped rod, slightly dilating at apex; curving mesad near apices ( Fig. 293). Harpagones weakly curving posterodorsad ( Fig. 291, 293). Phallotheca shallow ( Fig. 294), with weakly developed, ventrad curving anterior part; horizontal section with straight dorsal margin, ventral margin slightly concave, small constriction present at mid-length. Endophallus long, running through entire phallotheca, ending in narrow tube at gonopore. Chitinized endothecal process triangular, ovoid, curving ventrad; phallotremal sclerites vertical in lateral view. Vestigial, membranous, ventral endothecal lobes visible but weak.
