Diagnosis.
Females with median septum narrower than in
M. transversa
sp. nov.
, having only a small or no pit at the anterior end of median septum, rims around copulatory openings forming a larger circle (
Figs 13, 17–18, 20
), lateral loops of internal duct system extending posteriorly to receptacula (
Figs 14–16
). From the present material the colour pattern of
M. minuscula
comb. nov.
seems to be more distinct than in
M. transversa
sp. nov.
(
Figs 29–30
).
