Allodia jaschhofi

description: Allodia jaschhofi Magnussen sp. nov.
(Figs 7, 8)
Diagnostic characters. A. jaschhofi can best be separated from the other species described here, based on the following combination of characters: Length of rm equal to length stem of the posterior fork; the dorsal lobe of gonostylus is similar to A. karkloofensis, which both have a large membranous area on the internal apex of the lobe (Fig. 10); the median lobe is not distinctly separable from the other species; the basal part of the gonostylus is similar to that of A. karkloofensis, but with a small pointed structure present, which is absent in A. karkloofensis (Fig. 9). The female (Fig. 8) can be separated from A. nyeriensis on shape of hypogynal valves (Fig. 2).
Type material. Holotype ♂. South Africa: Central Drakensberg, Cathedral Peak Nature Reserve, Rainbow Gorge (28.9516°S, 29.2183°E, 1500 masl), sweep-net, old growth indigenous forest. 0 4 Des. 2005. TSZD-JKJ- 101654. Leg. M. Jaschhof. (TMU). Paratype 1 ♀, data as for holotype. (TMU).
Measurements. Male: Body length 3.10 mm; wing length 2.6 mm. Female: Body length 3.65 mm; wing length 2.78 mm.
Coloration. Head and clypeus brown. Mouthparts and palpomeres whitish yellow. Antennae brown, with scape, pedicel and first half of first flagellomere whitish yellow. Scutum brown. Lateral sclerites brown. Wings clear without markings. Halteres whitish. Legs whitish. Abdomen brown. Terminalia whitish yellow.
Head. Two ocelli, located close to the eye margin. Head covered with fine trichia, except for row of about 5 short setae near eye margin, above ocellus. Antennae in male about twice as long as thorax, in female slightly longer than thorax (1.22 mm/0.74 mm, respectively). Scape and pedicel with several setae on distal third. Flagellomeres cylindrical, densely clothed with fine trichia. First flagellomere twice as long as scape.
Thorax. Antepronotum with 5 strong setae. Scutum covered with uniform small, pale setae, with strong lateral prealar and postalar setae. Discal bristles absent. Scutellum with 2 strong bristles. Laterotergite with 6 long setae. Other lateral sclerites bare.
Legs. Fore-, mid and hind tibiae with short setae arranged in rows. Mid tibia with 8 anterodorsal and 25 posterodorsal bristles, on distal 3/4 of segment. Hind tibia with 7 anterodorsal and 8 posterodorsal bristles.
Wings. Sc short, ending in R, length of rm equal to length of stem of posterior fork, base of anterior fork distinctly before base of posterior fork. R1 and R5 with setae, absent at basis of veins.
Male terminalia (Fig. 7). Tergite 9 medially divided, each part rounded, covered with minute trichia, with two strong bristles and four small setae. Cerci clothed with fine trichia, with long setae apically; pseudocerci with several long setae medially and apically. Dorsal lobe of gonostylus oblong, apex prominently rounded, with large, round membranous area internally; outer surface with numerous strong setae. Median lobe with slightly curved ventral side, but without heel-shaped posteroventral corner; 8 strong and 3 shorter setae on posterior margin; two small setae on dorsal edge; one long seta on posterior edge, with long distance from ventral margin (less than half of the total distance from basis). Ventral lobe slightly club-shaped, with 5 long and three short setae at apex. Basal part of gonostylus with three structures; dorsal structure small and pointed with 1-2 small setae, middle structure round with one long seta and ventral structure large, rounded with several short setae (Fig. 7C).
Female terminalia (Fig. 8). Tergite 8 short. Cerci two-segmented; first segment oblong, slightly arcuate, fused at basis; second segment egg-shaped, narrower than first segment, with several long setae (Figs 8A, 8B). Gonapophyses fused, membranous, tongue-shaped with small setae around edge. Hypogynal valves elongated, triangular shaped, blunt, slightly curved towards apex; one long seta on tip; labia membranous (Fig. 8C). Etymology. Named after the collector.
Remarks. The specimen has become pale after years of storage in ethanol. Measurements were made on specimen in ethanol.
