New Caledonia , Mt. Tinchialit , 2020 ft. , 22.viii­ 10.ix.1949 , at light [ L. E. Cheesman ] ( BMNH , mounted on 3 slides) . FIGURES 51­52. Mecynostomella fusca Kimmins, 1953 , male holotype. 51, genitalia, lateral view; 52, phallus, lateral view. Diagnosis: In fusca , the forewings have a dark area densely covered by cone­shaped sensillae as in flinti . The species is easily separated from flinti and congeners by the presence of long lateral branches originating below segment X. The genitalia are unique in the undulated posterior margin of segment IX, a short segment IX, presence of lateral branches below segment X, and apex of segment X that in lateral view is wider than in flinti . Description of the male and female is given in Kimmins (1953: 255­257) . To the original description the following head characters are added: Tentorium ( Fig. 2 ) with long anterior tentorium arms bearing pointed vestigial projections at dorsal margin; tentorial bridge broad, straight, with long, pointed anteromesal protuberance. Maxillary palp ( Fig. 3 ) slightly shorter than labial palp ( Fig. 4 ). Membrane between palp segments densely covered by dark microtrichiae ( Fig. 5 ) also present on the segments. Wings ( Fig. 12 ) with dark area in anal and cubital region made from densely grouped, dark sensillae. Genitalia ( Figs 51­52 ) as in Kimmins (1953) but in lateral view with more setae along posterior margin of segment IX, and gonocoxite with dorsal setae ( Fig. 51 ). Phallus ( Fig. 52 ) similar to that of flinti, except anteriorly narrower and posteriorly wider.
