Figs. 15 A–C
Male. Colour. Head brown, face yellowish brown. Antenna pale brown. Clypeus yellow, mouthparts pale yellowish. Thorax pale brown, medial part of scutum and scutellum at least seemingly darker brownish. Legs (femur, tibia and tarsus 3 lost) yellowish, base of trochanters 3 infuscated. Wing pale brown; haltere pale brown, the knob dark brown. Abdominal tergites pale brown, sternites paler yellowish. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4 seen in ventral view in slide, apparently similar to Fig. 7 A (M. depilis). Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.3 times longer than palpomere 4. Number of strong postocular setae ca. 10 (exact number not countable in the slide). Thorax. Anepisternum setose, with ca. 43 setae; anterior basalare nonsetose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with 15 setae. Legs. Mid tibial organ absent; hind tibiae lost in the single specimen. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 not extending to the level of the tip of R1; wing length 1.4 mm. Hypopygium. Figs. 15 A–C: Sternite 9 laterally fused with gonocoxa, the posterior margin convex, not extending to the middle of gonocoxa, anterior margin deeply incised, the setae few, similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa convex, the ventral setae of gonocoxa unmodified; posterolateral part not drawn into a remarkable lobe. Parastylar lobe membranous, covered by the mesial margin of gonocoxa, with one seta. No paraapodemal lobe identifiable. Dorsal mesial margin of gonocoxa slightly lobe-like bulging mesiad, on posterior part with a row of 4 strong setae of which the posteriormost 2 are flat and dilated. Number of juxtagonostylar setae two, the ventral one is a rather unmodified megaseta, the dorsal one is flattened and dilated with two fine apices, both megasetae arising from a common basal body which is as long as the more dorsal megasetae. Anteriorly from the juxtagonostylar megasetae there is a curved lobe with ca. 5 fine apical setae and in a more anterior position a strong megaseta. Gonostylus bilobed, with flat, subquadrangular basal part and a narrow transverse apicodorsal part, the former with several setae at mesial margin, the latter with one apical seta. Aedeagus broadly subtriangular, the lateral sides slightly concave, with a pair of rounded membranous lobes ventrally near the apex, the apex straight, not curved ventrad. Hypoproct extending posteriorly to the base of gonostyli, the number of ventral setae (sternite 10) ca. 15 on each half. Cerci mesially separate.
Female. Unknown.
Discussion. Manota pisinna shares with M. mexicapan two characters not found in other Neotropical Manota species: 1) at the dorsal mesial margin of the gonocoxa, at the level of the juxtagonostylar megasetae, there is a row of 4 setae of which the posteriormost two are flattened and dilated, and 2) the apex of the aedeagus is straight, not curved ventrad. They differ from each other as follows: in M. pisinna the laterotergite is non-setose (in M. mexicapan setose), gonostylus is about as long as broad and has a long transverse apicodorsal setigerous lobe (ca. 3 times longer than broad with an inconspicuous lobe at the middle of the lateral margin in M. mexicapan), anteriorly from the juxtagonostylar megasetae there is a curved lobe with 5 fine setae at apex (with 3 megasetae in M. mexicapan) and anteriorly from this lobe there is a long oblique megaseta which is ca. twice as long as the setae on the lobe mentioned earlier (short, only half the length of the megasetae on the lobe in M. mexicapan).
Etymology. The name is Latin, pisinna, small, referring to the small size of the fly.
