Symplanella (Bambunella) cattiensis sp. nov.

( Figs 14–32 )

Description. Structure. Coryphe wide, 1.3 times as wide between the eyes as long medially, with convex anterior margin, deeply concave posterior margin, and lateral margin weakly convex ( Figs 14 , 18 ). Eyes large, each is 0.7 as wide as coryphe (in dorsal view) ( Fig. 18 ). Metope 1.5 times as long medially as wide between eyes, slightly enlarged above clypeus, with median carina running from its upper margin to basal part of anteclypeus and with sublaleral carinae running from its upper margin, but not reaching metopoclypeal suture ( Fig. 16 ). Median and sublateral carinae not joint at upper margin of metope. Metopoclypeal suture weak, slightly convex. Rostrum reaching hind coxae, with very short not narrowing apically third segment. Pronotum with acutely angulated anterior margin and deeply concave posterior margin, without carinae. Pronotum slightly shorter than coryphe medially. Paradiscal fields of pronotum not narrow. Paranotal lobes of pronotum elongate. Mesonotum large, nearly 2.5 times as long as pronotum, without carinae. Fore wings with elongate basal cell. Clavus long, 4/5 of whole wing length, reaching abdominal apex ( Figs 15 , 19 ). Clavus closed, Pcu + A 1 running to CuP before claval apex. Radius and median running by short common stem from the basal cell. Forewing vein sequence: R 3, firstly furcating before nodal line; r-m 2; M 3–4, furcating after nodal line; m-cua 2–3; CuA 2–3, furcating after nodal line; cua-cup 1–2 ( Figs 19, 20 ). Hind wings as long as fore wings. Hind tibia with a single lateral spine below its middle and with six spines apically. First metatarsomere nearly three times longer than second one, both without spines.

Coloration. General coloration brownish light yellow ( Figs 14, 15 ). Coryphe, pro- and mesonotum with red median line ( Fig. 14 ). Upper half of metope between eyes light brown to brown. Lower half of metope and postclypeus and anteclypeus frontally dark brown to black ( Fig. 16 ). Ocelli surrounded by red. Pedicel with large black spot outside and with small brown to dark brown spot on inner side. Male paranotal lobes of pronotum and episternae and epimerae sometimes reddish. Fore and hind wings slightly opaque, with light brown veins. Hind coxae with black hind margins. Claws dark brown. Tips of leg spines black. Abdominal sternites with dark brown to black stripes anteriorly and laterally, including the lateral furrows ( Fig. 17 , lf). Abdominal tergites with wide dark brown lateral stripes. Male abdominal sternites and pygofer sometimes greenish. Female sternite VII sometimes reddish yellow.

Male terminalia ( Figs 21–30 ). Abdominal sternite II with wide and short apodemes ( Fig. 22 ). Pygofer elongate vertically, with vertical lobe-shaped processes on concaved hind margins below anal tube; posterior margins sharply concave; lower margin widely concave below styles ( Figs 23, 24 ). Anal tube large, protruding downwards (in lateral view), elongate, with obtusely angulate apex (in dorsal view) ( Figs 24, 25 ). Anal column wide. Penis massive, with aedeagal shaft strongly curved, U-shaped ( Fig. 28 , ash). Aedeagal shaft narrowing apically ( Fig. 29 ). Gonopore apical. Penis with pair of large processes ventrally ( Figs 27, 28 , vpp). Penis fused with connective which is fused with styles ( Figs 26, 27 , s). Style rounded, without processes ( Figs 27, 30 ).

Female terminalia ( Figs 17 , 31, 32 ). Sternite VII with very weak concavity of hind margin ( Fig. 31 ). Endogonocoxal lobes fused in shape of large conical sclerotization well visible behind hind margin of sternite VII ( Figs 31, 32 , GxL).

Total length (from apex of coryphe to the apices of fore wings). Males—5.5–6.0 mm. Females—6.0–6.2 mm.
