Figs 9 A–D
Male. Colour. Head pale brown, frons, vertex and dorsal part of occiput darker brown. Antenna brown, scapus and pedicellus slightly paler brown. Mouthparts pale yellowish. Thorax rather unicolorous brown. Legs pale yellowish, apex of coxa 2, base of coxa 3, trochanters 2 and 3 obscurely infuscated, base and apical third of femur 3 more strongly infuscated, especially the apical part which is almost as dark as thoracic dorsum. Wing unicolorous greyish-brown; haltere yellowish-brown with dark brown knob. Abdomen brown, all the sternites appearing paler. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 9 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment. Number of strong postocular setae 10–11. Thorax. Anepisternum setose, with 30–39 setae, anterior basalare setose, with 3–7 setae, preepisternum 2 setose, with 17 setae, laterotergite non-setose, episternum 3 setose, with 5 setae. Wing. Length 2.1–2.2 mm. Hypopygium, Figs 9 B–D: Sternite 9 about half of the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin with a deep medial notch continuing anteriad as a medial furrow dividing the sternite into two halves, anterior margin deeply incised, the setae long, similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, convex. Parastylar lobe large, with numerous setae at margin. Paraapodemal lobe distinct, well exposed in ventral view. Dorsal mesial margin of gonocoxa simple, subapically with a small setose lobe; with a plate-like lobe at the apical part of the dorsal mesial margin, placed on a more ventral level and bearing a curved row of ca. 10 strong pointed setae on its ventral side. Two juxtagonostylar setae present, both rather unmodified megasetae which are widely separated and arise from a low common basal body. Gonostylus simple, elongate-oval, both ventral and dorsal sides with moderately long unmodified setae, at the apical half of the mesial margin with a row of 5 strong setae differing from the other setosity. Aedeagus elongate-subtriangular, with weak lateral shoulders, the apical part straight, not curved ventrad. Hypoproct posteriorly extending to the middle of gonostylus, with ca. 15 setae on each half, three of the setae at posterior margin conspicuously strong. Cerci mesially separate.
Female unknown.
Discussion. M. seducta resembles M. clavulosa from which it is distinguished e.g. by the following characters: 1) the hypoproct has posteriorly a transverse row of three strong setae plus one weaker one, whilst in M. clavulosa there is only one strong and one weak seta; 2) the mesial setae on the hypoproct are very long and fine, whilst in M. clavulosa they are short and claw-like; 3) the ventral plate-like lobe at the apical part of the dorsal mesial margin of gonocoxa has on its ventral side a row of ca. 10 strong sharp setae, whilst in M. clavulosa the number of setae is ca. 5 and they are very strong and blunt; 4) the strong setae at the mesial margin of the gonostylus are much longer than in M. clavulosa and they are all about equal in length, not decreasing in length towards the apex of gonostylus as in M. clavulosa. M. seducta and M. clavulosa resemble M. chi, M. planilobata and M. subseducta, from which they differ e.g. by lacking a crescent-shaped large lobe on the hypoproct. All the mentioned species resemble M. mirifica, M. submirifica and M. aconcinna but differ by the symmetrical apex of the aedeagus.
Etymology. The name is from Latin, seducta, apart, and refers to the widely separated halves of sternite 9.
