Pseudosymplanella (Nelobamba) kubani sp. nov.

( Figs 33–51 )

Description. Structure. Eyes large, each is 0.6 as wide as coryphe (in dorsal view) ( Figs 33 , 37 ). Coryphe almost square, 1.3 times as wide between eyes as long at midline, with convex anterior margin, deeply concave posterior margin, and lateral margins nearly straight.. Coryphe with short median carina developed only basally ( Fig. 37 ). Metope as wide between eyes as long medially, enlarged above clypeus, with median and sublateral carinae running from its upper margin separately ( Fig. 35 ). Median carina running throughout postclypeus; sublateral carinae not reaching metopoclypeal suture. Metopoclypeal suture strongly convex. Rostrum reaching hind coxae, 3 rd segment short and wide. Metope and coryphe joint at acute angle in lateral view ( Fig. 34 ). Pronotum with convex anterior margin and deeply concave posterior margin, without carinae. Paradiscal fields of pronotum not narrow. Paranotal lobes of pronotum elongately oval. Mesonotum twice longer than pronotum medially, without carinae. Fore wings long and narrow, with narrowly rounded apices, surpassing beyond abdominal apex at 1/5 of its length; without nodal line. Clavus long, 2/3 of whole wing length, reaching abdominal apex. Clavus opened, Pcu + A 1 running to its apex. Basal cell long and narrow. R and M running by one short stem from the basal cell ( Fig. 38 ). Forewing vein sequence: R 2, furcating apically; r-m 2; M 3–5, furcating apically; m-cua 2; CuA 1–2; cua-cup 1 ( Figs 38, 39 ). Hind tibia with a single lateral spine medially and two lateral and four (3 + 1) intermediate spines apically. First metatarsomere nearly three times as long as second one. First and second metatarsomeres without spines. Hind margin of arolium of pretarsus surpassing beyond claw apices in dorsal view.

Coloration. General coloration straw-yellow ( Figs 33–36 ). Metope whitish above clypeus ( Fig. 35 ). Postclypeus light brown basally, sometimes with brown stripes. Pedicel with a large black spot. Ocelli surrounded by red. Fore and hind wings slightly opaque. Claws and tips of leg spine black.

Male terminalia ( Figs 40–49 ). Abdominal sternite II with long and narrow apodemes each bearing spine-shaped process on its inner side ( Fig. 49 ). Pygofer wide; hind margins concave below anal tube, with long undulating filiform processes ( Fig. 40 ). Lower margin of pygofer weakly convex medially ( Fig. 41 ). Anal tube large (in lateral view), slightly longer than wide medially (in dorsal view), with pair of short processes ventro-apically ( Figs 40, 42, 43 ). Anal column long, 1/3 of anal tube length. Penis fused with connective, with tubular-shaped and curved aedeagal shaft (in lateral view) ( Fig. 44 ). Aedeagal shaft wide, with denticles laterally below apex (in ventral view) ( Fig. 45 ). Gonopore apical ( Figs 44–46 ). Style with wide plate and wide capitulum bearing denticles ( Fig. 47 ). Styles fused medially with a large elongate lobe between them ( Fig. 48 , ls).

Female terminalia ( Figs 36 , 50, 51 ). Hind margin of female sternite VII sharply concave medially, with angularly protruding margins of this concavity ( Figs 36 , 51 ). Endogonocoxal lobes fused in shape of large sclerotizaton, with a median carina ( Fig. 51 , GxL). Anal tube short, cylindrical, weakly concave apically (in ventral view) ( Fig. 50 ). Gonoplacs shortly triangular.

Total length (from apex of coryphe to the apices of forewings). Males—4.5 mm. Females—5.0 mm.
