Manota subferrata sp. n.

Figs 10 A, B, C

Male. Colour. Head brown, face and clypeus paler brown. Antenna brown, scapus and pedicellus paler brown. Mouthparts pale yellowish. Thorax brown, posterior part especially on the dorsal side more or less extensively and intensively darker brown. Legs pale yellowish, trochanters 2 and 3 more or less infuscated, hind femur infuscated on basal third, especially on dorsal and ventral sides. Wing unicolorous greyish- or yellowish-brown; haltere yellowish-brown with dark brown knob. Abdomen brown, sternites 3–4 paler. All the setosity yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 10 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 5–6 apically expanded curved sensilla; palpomere 4 with parasegment. Number of strong postocular setae 11. Thorax. Anepisternum setose, with 46–61 setae, anterior basalare non-setose, preepisternum 2 setose, with 21–27 setae, laterotergite non-setose, episternum 3 setose, with 16–21 setae. Wing. Length 1.7–2.1 mm. Hypopygium, Figs 10 B, C: Sternite 9 about half of the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin membraneous, transverse, anterior margin deeply incised, the setae similar to the shorter ventral setae of gonocoxa. Ventral mesial margin of gonocoxa slightly sigmoid, the setae at the margin conspicuously stronger than the more lateral setae. Parastylar lobe slightly oblique and sickle-shaped, narrowing anteriad, with two setae anteriorly. Paraapodemal lobe distinct, well exposed in ventral view. Dorsal mesial margin of gonocoxa simple, apically roundly angular with setae at the margin. Laterad from the latter with a long apico-lateral lobe bearing numerous apicomesial setae and a few basomesial setae. Two juxtagonostylar setae present, both of them slender megasetae which are subequal in size and sigmoid, and arise from a common basal body which is about one-third of the length of the setae. Gonostylus simple, elongate, both apico- and baso-mesially produced lobe-like, the ventral side nearly completely moderately long setose, the dorsal side with similar setae but at middle and basally largely non-setose, at the baso-mesial lobe-like angle with a group of three conspicuously long setae. Aedeagus subtriangular, with lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the level of the base of gonostylus, ventrally with ca. 10 setae in a mesial longitudinal zone on each half. Cerci mesially separate. Female unknown.

Discussion. M. subferrata is similar to M. ferrata , known from Selangor, Malaysia. The two species are distinguished e.g. by following characters: 1) in M. subferrata the setae of sternite 9 are subequal, whilst in M ferrata there are 3–4 setae on the posterior part which are conspicuously stronger than the others, equalling the difference between the setae on sternite nine and those at the ventral mesial margin of gonocoxa in Fig. 10 B; 2) in M. subferrata the baso-mesial angle of gonostylus forms a heel-like lobe, whilst in M. ferrata it is rounded; 3) in M. subferrata the long setae on the latter structure do not greatly differ in thickness from the other nearby setae, whilst in M. ferrata they are twice as thick; and 4) in M. subferrata the setae apico-dorsally on the gonostylus do not differ much from the other nearby setae, whilst in M. ferrata there are ca 10 setae which are conspicuously strong.

Etymology. The name is derived from Latin sub-, somewhat, and the name of Manota ferrata and refers to the close similarity of the two species.
