third, with apical membrane including all of apical cells. Other external 
characters as in M. retrorsa, n. sp. 
Male pygofer moderately produced with apex rounded, with more than fif- 
teen anteapical macrosetae, with a very short curved undifferentially sclero- 
tized dorsoapical process extending mesally then apically; plates extending 
posteriorly almost as far as posterior pygofer margin, each with a weak con- 
vexity near midlength in lateral view, in ventral view gradually tapered in 
basal half, with uniseriate macrosetae; style extending posteriorly slightly 
farther than apex of connective, without preapical lobe, narrowly rounded 
apically; connective elongate triangular, with a median keel; aedeagus biun-
