Mecynostomella hollowayi Johanson 2003, sp.n.

Description

Mecynostomella hollowayi sp.n.

(Figs 6­11, 36­40, 53)

Material examined: Male holotype: Plateau N Col d'Amos, 13.vii. 1971, 440 m (#46) [J.D. Holloway] (ROM, alcohol). 2 male paratypes: N Mt. Aoupinié, 520 m, Haut Mou, Napoue Areu valley, 30­31.vii.1971 (#62) [J.D.Holloway] (NRM, alcohol). 3 male paratypes: same, except (ROM, alcohol). 1 male paratype: Province Sud, stream at Koghi Mt., 22°10.722'S, 166°30.501'E, 462 m, light trap, 6.xii.2001 [Johanson, Pape, Viklund] (NRM, alcohol).

Etymology: hollowayi, named after J. D. Holloway who collected the species. To be treated as a noun in genitive case.

Diagnosis: The species has a pale area present between the forewing Cu and A, as in sigma. The two species are separated by the longer and slightly ventrally curving lateral branch, and shorter median branch in hollowayi.

Male.

Colors faded. Antennal flagellum with 42 flagellomeres.

Thorax: Pronotum with stout, dark brownish setae not confined to distinct warts.

Wings (Figs 6­11): Forewing length 8.5­10.2 mm (n=5), hind wing length 7.3­9.3 mm (n=5). Forewing pale brownish, with distinct pale area between A and Cu (a in Fig. 6) formed by densely arranged modified sensillae (Fig. 11). Hind wing pale grey. Venation as described for genus.

Genitalia (Figs 36­40): Segment IX, lateral view (Fig. 36), about 2.1x higher than long; anterior part shallowly produced, with rounded, undulating margin; dorsal margin narrowly rounded; in ventral view (Fig. 38), ventral margin with wide hyperbolar, incision. Segment X simple; in dorsal view (Fig. 37), central branch about parallel­sided at distal half; in lateral view (Fig. 36), proximally nearly parallel­sided, tapers distally, dorsal margin slightly bent ventrally at mid­length; lateral margin with few setae on distal half, about 2x longer than high (Fig. 36), apex narrowly rounded in lateral view, slightly incised in dorsal view (Fig. 37). Lateral branch nearly as long as central branch, tubular, slightly curving ventrally along (Fig. 36), slightly converging in dorsal view (Fig. 37); short apical setae present, proximal setae grouped with setae on segment IX. Median branches large, hidden in dorsal view (Fig. 37), with short setae on ventral margin (Fig. 36). Gonocoxite, lateral view (Fig. 36), generally sub­straight, except apex produced dorsad; dorsal margin sigmoid, ventral margin sub­straight (Fig. 36); incised sub­apical part about 0.7x as high as proximal part; sub­straight in ventral view (Fig. 38), oriented posteriad, covered by setae except at proximal part. Phallus simple; phallobasis about three­quarts the height of segment IX (Fig. 39); endotheca produced dorsally from dorsal opening starting midlength on phallus, without spines; in ventral view (Fig. 40), lateral incisions at proximal part located close to posterior margin of anterior opening.

Female unknown.
