Diagnosis.
Male. General colour shining black, including face, gena, thorax and abdomen; antennae reddish brown; frons rather dark reddish brown. Haltere with white stem and shining black knob. Two orbitals. Anterior dorsocentral seta half as long as posterior dorsocentral, the latter slightly shorter than scutellum length. Lateral scutellar seta subequal to scutellum length, lateral scutellar seta 0.8 times as long as apical scutellar. Legs shining black except for trochanters, apical parts of femora, basal and apical parts of tibiae, mid and hind tarsi reddish brown, and fore tarsus dark brown. Mid tibia: proximal anterodorsal seta longer than distal anterodorsal, distal dorsal seta slightly longer than width of mid tibia, apical sixth of tibia with a row of short ventral setae terminating in short ventroapical seta, which is slightly shorter than width of mid tibia. Mid femur with a row of posteroventral setae. Wing and veins reddish brown, Cs2 brownish black in basal half. Sternite 6 (
Fig. 82
) with two black, haltereshaped lobes. Abdomen heavily sclerotized.

Comments.
Based on possible synapomorphies: sternites 5 of male with a row of comb-like spines and long spine-like setae on posterior margin, sternite 6 with a pair of posterior processes, gonostylus with 3 spines,
M. guestphalica
(

M. intercepta

,
M. ismayi
Roháček, 1983
,
M. vixa
Marshall
, 1985
and
M. obtusispina
Su, 2013
could belong to
M. guestphalica
species group (called incorrectly
M. v-atrum
group by
Roháček &
Marshall
, 1988
because true
M. v-atrum
was later synonymized with
M. splendens
belonging to
M. dissimilicosta
group), in which
M. intercepta
,
M. ismayi
and
M. obtusispina
seem to be more closely related based on orange antennae as proposed by
Marshall
(1985)
, but relationships among them are not clear. We think that
M. intercepta
and
M. obtusispina
could be sister species according to sternite 6 of male with relatively long, apically blunt lobes, cerci of male not distinctly separated and postgonite relatively straight.
