description: <i>Orthopsyche anulmika</i> Oláh &amp; Johanson, new species Fig. 275–278 This species is close to <i>O. mcfarlanei</i> Oláh &amp; Johanson, but easily distinguished in lateral view by the gradually narrowing harpagones which in ventral view curve mesad. In <i>O. mcfarlanei</i> the harpagones are parallelsided along their length in lateral view, and straight in ventral view. Other differences are the deeper intersegmental depression and the smaller sclerotized endothecal process, as well as the half as broad endophallus in <i>O. anulmika</i> compared to in <i>O. mcfarlanei</i>. Male. Large, brightly yellow animal with ochraceous forewing membrane; body light brownish, eyes ebony black; legs fulvous. Maxillary palp formula is I-II-III-IV-V. Dorsum of head with 9 almost indiscernible setal warts, not clearly visible due to their bright yellow colour. Swollen setal wart present on proepisternum. Pretarsal claws symmetrical, without laterally flanked setal bundle. Spur formula 244. Wings. Venation typical for the genus, except median cell on hind wings closed. Forewing pterostigma enlarged, corneous. Sc meeting R immediately before C. Crossvein r tangential with crossvein s. Hind wing Sc meeting R apically of crossvein r by length equal to length of crossvein r. Crossvein r basally of s by distance equal to length of crossvein r. Crossvein m present. Fork 1 present. Forewing length 14.5 mm. Male genitalia. Abdominal segment IX fused annularly, narrow (Fig. 275). Median keel triangular in dorsal view (Fig. 276); narrowing apically, with granulose dorsal and lateral surfaces; triangular keel representing entire dorsum of segment IX, shifted posterad. Sternum shortening abruptly (Fig. 275). In lateral view, anterior margin bow-shaped, arciform; upper half shifted gradually; lower, smaller part shifted more abruptly; middle part rounded, like a drawn bow (Fig. 275). Apical lobe on posterolateral margins well developed, nearly triangular (Fig. 275); located immediately above basis of gonocoxites. Antecosta well developed on each side, widening before margins; each with external groove of antecostal suture. Posterior row of spines continuous (Fig. 275). Intersegmental depression between dorsum of segments IX and X deep, obtusely angled, widely V-shaped. Segment X forming compact quadrangular body with setose processes in lateral and dorsal view (Fig. 275, 276). Setose areas (superior, or preanal appendages) rounded, with light background, located apicoventrally. Apicoventral setose lobes curving posteromesad, with dorsal hump. Dorsum of segment X dominated by central, setose ridge; triangular in lateral view (Fig. 275), representing pair of fused apicodorsal setose processes visible in dorsal aspect (Fig. 276). In lateral view, obliquely directed dorsad. Transverse suture located in bottom on each side of intersegmental depression, wide. Longitudinal sutures present. Coxopodites with slightly S-shaped dorsal margin; distal half dilating (Fig. 275); nearly straight in ventral view (Fig. 277). Harpagones less than half as long as coxopodites, gradually narrowing distad till apical one-third (Fig. 275), slightly curving mesad with slightly clavate apex in ventral view (Fig. 277). Phallotheca almost parallel-sided, cylindrical, without basally section (Fig. 278); anterior ventrad curving part obtusely angled around 150 o. Dorsum of phallotheca concave; in lateral view slightly depressed at mid-length. Chitinized, endothecal process small, nearly reniform, less than half as wide as end of phallotheca; completely covering narrow, well sclerotized, phallotremal sclerites, located obliquely vertical. Ventral endothecal process circular, well sclerotized, without spine brush. <b>Male</b> <b>holotype</b>: <b>NEW CALEDONIA:</b> Province Nord, Mt.
