Treatment

63. Neoperla muyukae n. sp.

( Figs. 362–364 View FIGURES 362–364 )

Type Material. Republic of Cameroon, 1 ♀, holotyp e, Muyuka [4°43’18’’N, 9°38’27’’E; 305m], Victoria Div., Brit Cameroons,VI-25-49 B.Malkin at light (slide Z19.20, SMNS) GoogleMaps .

Habitus. ♀ 13.3 mm. Pale, yellowish, a light brown mark between the ocelli, flagellum distally brownish.

Male. Not known; compare Neoperla sp. Afr_A.

Female ( Fig. 362 View FIGURES 362–364 ). S8 caudally projecting, parabolic, with three large brown spots around a pale anchor-mark. Pilosity on the paired anterior spots is denser and shorter than on the rest of sternite, the anchor mark and the caudal spot are bare. Vagina calyx-shaped, the dorsal side with numerous fine, pale spicules in transverse rows. Spicules extend into the short wide base of the SSt which is distally completely scaly. The SSt is long and slender and of uniform diameter.

Egg ( Figs. 363–364 View FIGURES 362–364 ). Oval and widest at midlength. No visible eclosion line, anchor pole without collar.Anchor mushroom-shaped, the anchor cavity is wide and funnel-shaped. The roughly 30 striae with slight left hand spin reach to near the punctate top of the operculum ( Fig. 363 View FIGURES 362–364 ). Costae are wide, flat, impunctate, sulci are narrow slots, the two lines of micropunctures hardly diverge around the micropyles ( Fig. 364 View FIGURES 362–364 ).

DNA. No data.

Note. By female S8 (but not by the eggs) N. muyukae n. sp. seems to be a close relative of N. conradti . Males of the two species may also be similar but we know none resembling N. conradti . A quite different male initially tentatively associated with N. muyukae n. sp. is described below as Neoperla sp. Afr_A.
