FIGS 23-26. Female copulatory papilla in lateral and dorsal views. 23-24, M. bruneonervus . 25-26, M. rufidulus . Dotted areas represent membranous parts. Scale bar = 1 mm.

DESCRIPTION.— Species close in shape, size and coloration

to M. neoplumus , M. flavomaculatus and M. caledonicus .

Head: general coloration dark reddish brown; black

coloration of vertex more extended than in M. caledonicus (Fig.

6) posteriorly and laterally reaching cheek and surrounding

white line posterior to eye; face dark reddish brown, with a

dark stripe on fastigium and frons and two yellow spots below

each eye. Pronotum more slender than in M. caledonicus ,

uniformly dark reddish brown as in M. caledonicus .

Male FW venation (Fig. 9): no stridulatory apparatus.

Dorsal field greyish brown, pubescent, with 10 longitudinal

veins thinner than in M. caledonicus . Bases of 1A-4A thick

and yellow, bases of 1A-3A fused by a yellow sclerotization;

1A with yellow parts along its length; transversal veins

between 1A and CuA yellow. CuA brown basally then

yellow; MP yellow basally, then brown; MA and R brown.

Intermedia area brown with yellow sclerotization in anterior

fourth; transversal veins thick and yellow. Lateral field

grey brown, longitudinal veins bifurcating from R brown

basally then yellow. Legs. FI-II dark reddish brown, FIII

yellowish brown, knee reddish brown; tibiae whitish,

as in a variation of M. caledonicus ( Desutter-Grandcolas

1997b). Subgenital plate yellow brown with a median

dark stripe.

Male genitalia: very close to above species but differing by

relative sizes of components. Pseudepiphallus longer than

in M. caledonicus , anterior margin, folded dorsally narrower

than rest of sclerite (wider in other species); rami parallel;

apex of pseudepiphallus raised dorsally larger than in M.

caledonicus, as in M. neoplumus (Otte et al. 1987) . Ectophallic

fold thinner and longer than in M. caledonicus , reaching apical

part of pseudepiphallus, posteriorly to parameres, but not

to apex as in M. flavomaculatus . Lateral arms of endophallic

endophallic apodeme large, curved dorsally.

MEASUREMENTS. — Holotype male. PronL: 3.0 mm; PronW: 2.3 mm; FIIIL: 11.0 mm; FIIIW: 2.4 mm; TIIIL: 10.5 mm; FWL: 15.8 mm; FWW: 3.3 mm.
