Manota inermis sp. n.

Figs. 8 A–E

Male. Colour. Head brown, face somewhat paler. Antenna brown. Clypeus brown, mouthparts pale yellowish. Thorax brown. Legs yellowish, hind leg darker than the others, its tibia pale brown; coxae 2 and 3 at extreme base, trochanters 2 and 3, femur 2 at basal and apical fourth and femur 3 on basal fourth and apical third infuscated. Wing pale yellowish brown; haltere pale brown with darker brown knob. Abdomen brown, sternites paler than tergites. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Antennal flagellomere 4, Fig. 8 A. 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 11–13. Thorax. Anepisternum setose, with 69–84 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose; episternum 3 setose, with ca. 20 setae. Legs. Mid and hind tibial organs absent. 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 2.4 mm. Hypopygium. Figs. 8 B–E: Sternite 9 laterally free from gonocoxa except anteriorly, the free lateral margin oblique, posterior margin transverse, not reaching the middle of gonocoxa, anterior margin rather shallowly incised, the setae weaker than the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, continuing as the mesial margin of long posterolateral lobe; the ventral setae of gonocoxa unmodified, mesially on the posterolateral lobe a row of conspicuous slightly stronger curved setae. Parastylar lobe large, non-setose. Dorsal mesial margin of gonocoxa simple; at this margin on the posterior half there is a small lobe bearing an aggregation of setae. Number of juxtagonostylar setae two; the ventral one is a flattened, sabre-like megaseta, the dorsal one is geniculate with an expanded membranous basal part, both megasetae are arising from a common basal body which is a little shorter than the megasetae. There are no additional prominent setae dorsally on the gonocoxa, of which setosity is otherwise similar to that on the ventral side. Gonostylus very elongate oval, with unmodified setosity on mesial and apical parts but with non-setose lateral part. Aedeagus broadly subtriangular, without lateral shoulders, with straight sides, the apex curved ventrad. Hypoproct extending posteriorly to level of middle of gonostyli, the number of unusual long ventral setae (sternite 10) ca. 30 on each half. Cerci mesially fused.

Female. Unknown.

Discussion. The non-setose anterior basalare and laterotergite, the large non-setose parastylar lobe, the presence of lateral margin on sternite 9 and the lack of any stronger setae or megasetae at the dorsal mesial margin of the gonocoxa – in addition to the juxtagonostylar setae – group Manota inermis together with M. multisetosa Jaschhof & Hippa and M. tapantiensis Jaschhof & Hippa. However , these species are otherwise dissimilar including numerous details of the male terminalia. Manota inermis differs from both by having a long posterolateral lobe on the gonocoxa which is ventroapically armed with a row of conspicuous curved setae and by having unusually long setae ventrally on the hypoproct (cf. Figs. 8 D, E, Jaschhof & Hippa 2005: figs 5 and 6).

Etymology. The name is Latin, inermis , unarmed, referring to the lack of megasetae anteriorly at the dorsal mesial margin of the gonocoxa.
