Genus Pseudosymplanella Che, Zhang et Webb, 2009

Pseudosymplanella Che, Zhang et Webb, 2009: 50 . Type species: Pseudosymplanella nigrifasciata Che, Zhang et Webb, 2009 , by original designation.

Diagnosis. Coryphe and metope wide. Fore wings not narrowing or weakly narrowing apically, with long clavus and without nodal line. Abdominal sternites IV–VI each with deep lateral furrows, apparently separating sternites and pleurites, not reaching its hind margins. Hind margins of male pygofer with long filiform processes below anal tube. Penis tubuar, strongly curved (in lateral view), without processes basally.

Composition and distribution. Three species known from southern China, northern Laos, and northern Thailand.

Key to the subgenera and species of Pseudosymplanella

1. Metope, except light carinae and band above clypeus, postclypeus, pronotum, mesonotum, and fore wings up to nodal line brown to dark brown or black ( Che et al. 2009, figs 1–3). Style narrow, hook-shaped apically ( Che et al. 2009, figs 18, 19). Hind margin of female sternite VII notched medially, endogonocoxal lobes not fused............................................................................ Pseudosymplanella s. str. ( P. nigrifasciata Che, Zhang et Webb, 2009 )

- Generally green or straw-yellow, except pedicel with a black spot and postclypeus sometimes brown ( Fig. 35 ). Style wide, not curved apically ( Figs 47, 48 ). Hind margin of female sternite VII sharply concave medially, endogonocoxal lobes fused in shape of large sclerotizaton ( Figs 36 , 51 , GxL). Nelobamba subgen. nov.............................................. 2

2. Postclypeus dark brown to black basally ( Gong et al. 2023, fig. 6). Styles medially not fused ( Gong et al. 2023, figs 12, 14). Lower margin of male pygofer deeply concave (in caudal view) ( Gong et al. 2023, fig. 12). Hind margin of female sternite VII with rounded margins of medial concavity ( Gong et al. 2023, figs 17, 19). Males—5.1 mm, females—6.0–6.2 mm............................................................................... P. maxima Gong, Chen et Yang, 2023

- Postclypeus straw-yellow or light brown, with brown stripes ( Fig. 35 ). Styles fused medially with a large elongate lobe between them ( Fig. 48 , ls). Lower margin of male pygofer weaky convex (in caudal view) ( Fig. 41 ). Hind margin of female sternite VII with triangularly protruding margins of medial concavity ( Fig. 51 ). Males—4.5 mm, females—5.0 mm.... P. kubani sp. nov.
