Symplanella (Symplanella) breviceps Fennah, 1987

( Figs 1–13 )

Symplanella breviceps Fennah, 1987: 245 , figs 1–9.

Supplementary description. Structure. Coryphe elongate, 1.5 times as long medially as wide between eyes, with obtusely angulate anterior margin and sharply concave posterior margin ( Fig. 1 ). Eyes large, each is as wide as coryphe (in dorsal view). Metope narrow, twice longer than wide between eyes, slightly enlarged above clypeus, with distinct median carina running throughout postclypeus and sublateral carinae not reaching metopoclypeal suture ( Fig. 3 ). Median and sublateral carinae joint at one point at upper margin of metope. Ocelli present. Rostrum with short and thick apical segment. Pronotum with narrow medial part and strongly acutely angulated anterior margin. Paradiscal fields of pronotum not narrow. Paranotal lobes nearly oval. Fore wings long and narrow, not narrowing apically, with a nodal line ( Fig. 2 ). Fore wings with elongate basal cell. Clavus long, 4/5 of whole wing length, reaching abdominal apex. 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 2–4, furcating after nodal line; m-cua 2–3; CuA 1–2; cua-cup 1. Hind wings as long as fore wings. Hind tibia with a single lateral spine medially and with two lateral and four (3 + 1) intermediate spines apically. First metatarsomere 3–4 times as long as second one. First and second metatarsomeres without spines.

Coloration ( Figs 1–3 ). Coryphe, pro- and mesonotum with wide red stripe medially. Metope pale, sometimes reddish between eyes. Pro- and mesonotum red laterally. Clypeus, fore and middle coxae, femora, apices of third tarsomeres, and claws dark brown to black. Pedicel with black spot. Fore and hind wings slightly opaque. Males with reddish veins of fore wings up to nodal line and black laterally abdominal sternites. Tips of leg spines black. Females with reddish abdominal tergites.

Male terminalia ( Figs 4–11 ). Abdominal sternite II with wide and short apodemes each bearing three spine-shaped processes on inner margins ( Fig. 11 ). Anal tube short, with deeply concave hind margin (in dorsal view) ( Fig. 6 ). Anal column wide. Pygofer elongate vertically, with weak processes of concaved hind margins below anal tube; lower margin without processes ( Figs 4, 5 ). Penis fused with connective, wide and flattened laterally, bottleshaped ventrally, with a short tubular apex ( Figs 7, 8 ). Gonopore apical. Style with long and narrow caudo-dorsal angle of the plate and long neck, with large capitulum and finger-shaped apical part ( Figs 9, 10 ).

Female terminalia ( Figs 12, 13 ). Hind margin of sternite VII widely concave, with endogonocoxal lobes fused in shape of large rounded sclerotization well visible behind its margin ( Fig. 13 , GxL). Anal tube short and wide, with widely concave hind margin (in ventral view) ( Fig. 12 ). Gonoplacs shortly triangular.

Total length. Males and females—5.0 mm (from apex of coryphe to the apices of fore wings).
