In the group with a broad male frons and 2 orbital setae, dorsocentrals 2+3, mid femur with 1 posterior preapical seta, but mid tibia with only one posterodorsal seta; prosternum bare; wing with no ventral setulae on node of R4+5 . FIGURES 41–56. Sternite 5; cercal plate and surstyli in dorsal view; epandrium, cercal plate and surstyli in lateral view; aedeagus in lateral view: 41–44 . Limnophora majuscula Emden. 45–48 . Limnophora melanota Emden. 49–52. Limnophora nuda sp. nov . 53–56 . Limnophora numerosa sp. nov . Description. General coloration. Ground-colour dark brown with grey-bluish dusting. Frontal vitta brown dusted; fronto-orbital plate, parafacial, face and gena silvery-white pruinose. Antenna, arista and palpus dark brown. Scutum brown with 2 grey-bluish vittae between acrostichal and dorsocentral rows of setae; postpronotal lobe, notopleuron, pleura and postalar callus light grey dusted with bluish reflexions. Scutellum brown, with a grey median vitta. Anterior spiracle grey-bluish. Wing clear. Calypters white, haltere yellow. Legs dark brown, coxae, trochanters and femora grey-bluish dusted. Abdomen dark brown, tergites 3–5 each with a triangular area of greybluish dust in anterolateral corners, syntergite 1+2 and tergites 3–5 with a narrow grey-bluish median vitta. Male. Body length: 3.6 mm ; wing length: 3.0 mm Head. Eye bare, frons at level of anterior ocellus about one-third of head-width, margins parallel; 2 pairs of inclinate frontal setae and 2 pairs of reclinate orbitals, and with some fine setulae outside the frontal setae; inner vertical seta long and outer one short; ocellar seta moderate. Antenna inserted a little above the mid-level of eye, postpedicel very long, almost reaching mouth-margin, about 4 times the length of pedicel; arista a little enlarged at base, almost bare, the hairs shorter than its basal width. In lateral view, mouth-margin projecting a little beyond level of profrons. Gena deep. Proboscis shining black; palpus filiform. Thorax. Dorsocentrals 2+3; acrostichal setulae in 2 rows, prescutellar pair not differentiated; 2 postpronotals; 1 presutural and 2 postsutural intraalars, posterior pair short; 1 presutural and 1 postsutural supraalar; 2 postalars, the posterior one very long; prealar absent; prosternum bare. Notopleuron with two setae similar in size. Scutellum with one sub-basal pair of setae and one long apical pair, lateral and ventral surfaces bare. Anepisternum with a posterior series of 4 setae, the second and the last longer. Katepisternals 1+2, the lower posterior seta fine. Lower calypter about 1.5 times the length of the upper one. Legs. Fore femur with rows of posterodorsal and posteroventral setae, the posteroventrals more spaced; fore tibia with 1 dorsal preapical and 1 posteroventral apical seta, both short; mid femur with 1 posterodorsal preapical; mid tibia with 1 median posterodorsal and 1 submedian posteroventral setae, one short dorsal preapical, and anteroventral, posteroventral and ventral surfaces with an apical seta, the latter the longest and strongest; hind femur with an anterodorsal row of setae, and 2 anteroventral setae on apical fifth; hind tibia with 1 anterodorsal median seta, 1 anteroventral submedian seta; dorsal preapical seta and ventral apical short. Wing. Veins bare, no ventral setulae on node of vein R4+5 ; veins R4+5 and M parallel at wing-tip; costal spine not differentiated. Abdomen. Tergites 3–5 with medium-sized setae, mostly lateral marginals. Sternite 1 bare. Sternite 5 as in Fig. 49 . Terminalia. Cercal plate and surstylus as in Figs 50–51 . Aedeagal complex as in Fig 52 . Female. Body length: 5.0 mm; wing length: 5.2 mm . Similar to male. Distribution. Republic of South Africa ( KwaZulu-Natal ). Etymology. The specific name is from the Latin “nudus”, meaning “naked”, and refers to absence of setulae on wing vein R4+5 . Remarks. In Emden’s (1951) key the new species runs to L. preapicalis at couplet 5, differing by the general colour of the body and by the bare R4+5 .
