7 Genal processes blunt ( Figs 111, 118 ). Body dimensions larger, forewing length> 2.0 mm. Paramere clavate, relatively evenly widening towards apical fifth, with a few bristles on the inner face in the middle near apex ( Fig. 138, 153 ). Female terminalia long,> 1.3 times as long as head width; proctiger at most weakly upturned apically ( Figs 157, 164 ).................... 8

- Genal processes subacute ( Figs 112, 116 ). Body dimensions smaller, forewing length <2.5 mm. Paramere lamellar, suddenly widened near apex, with a group of dense bristles on the inner face along the hind margin near apex ( Figs 140, 148 ). Female terminalia short, <1.3 times as long as head width; proctiger strongly upturned apically ( Figs 158, 162 )................ 9

8 Genal processes 0.7–0.9 times as long as vertex along midline ( Fig. 111 ). Large, antenna> 2.6 mm long, forewing> 2.4 mm long. Sclerotised apex of paramere hook-shaped, forward directed ( Fig. 136 ). Aedeagus with two large subapical spines ( Fig. 139 )......................................................................................... M. adusta

- Genal processes 0.5–0.7 times as long as vertex along midline ( Fig. 118 ). Small, antenna <2.5 mm long, forewing <2.5 mm long. Sclerotised apex of paramere truncate with slightly larger anterior and smaller posterior point ( Fig. 137 ).
