[Details of M. transversa male are taken from Jäger (2006)]

1a. Male............................................................................................... 2

1b. Female............................................................................................. 4

2a. Embolic apophysis separating distally from the embolus ( Fig. 5C ), conductor without disto-retrolateral extension, cymbial spur not hook-like ( Fig. 5E )............................................................................ 3

2b. Embolic apophysis separating medially from the embolus ( Fig. 2C ), conductor with disto-retrolateral extension, cymbial spur hook-like ( Fig. 2E )..................................................................... M. sanctor sp. nov.

3a. Embolus with a distal, oblique twist ( Figs 5B–C ), conductor wide, RTA short with three terminal branches and directed at 2- o’clock position in ventral view ( Figs 5C–D )...................................................... M. minuscula

3b. Embolus without distal, oblique twist, conductor strongly reduced, RTA long and directed at 1-o’clock position in ventral view......................................................................................... M. transversa

4a. Epigynal field oval, median septum without distinct anterior pit, median part of the internal duct system appears as paired, longitudinal tubes........................................................................................ 5

4b. Epigynal field roundish, median septum with distinct anterior pit ( Fig. 8A ), rims around the copulatory opening forming a narrow circle, anterior 2/3rd of median part of the internal duct system appears as a median, broad, longitudinal plate ( Fig. 8B )............................................................................................. M. transversa

5a. Median part of the internal duct system visible only at the posterior part of the median line ( Fig. 3B ), median septum with triangular posterior pit, rims around copulatory openings forming a small circle ( Fig. 3A )............... M. sanctor sp. nov.

5b. Median part of the internal duct system visible along the entire length of the median line ( Fig. 6B ), median septum with rectangular posterior pit, rims around copulatory openings forming a large circle ( Fig. 6A )...................... M. minuscula
