Symplana maurici sp. n.

( Figs 11–31 )

Diagnosis. Head with long apical part (after bend line), twice as long as the part of the head before this line ( Figs 11, 12 , 15, 16 ). Style with long capitulum. Hind margins of male pygofer with large triangular­shaped process below the anal tube. Female sternite VII with sharply concave medially hind margin and large furcating apically fused endogonocoxal lobes ( Figs 29–31 ).

Description. Generally, as mentioned for the genus. Coryphe long, more than five times as long as wide between the eyes, grooved at midline, narrow, slightly narrowing at bend line and apically; anterior margin rounded ( Fig. 16 ). Coryphe and metope joint at very acute angle (in lateral view) ( Fig. 15 ). Pro­ and mesonotum with distinct lateral carinae. Mesonotum three times as long as pronotum medially. Forewing vein sequence: R 3; M 5; CuA 2 ( Fig. 18 ). Hind tibia with six apical spines. Arolium of pretarsus wide, nearly reaching claw apices (in dorsal view).

Coloration ( Figs 11–14 ). Generally light green yellowish. Coryphe with unclear light brown longitudinal stripe medially sometimes invisible. Lateral margins of coryphe before bend line, lateral carinae of pro­ and mesonotum, and longitudinal veins of corium light green – fluorescent. Pro­ and mesonotum between lateral carina light brown. Forewings with brown­reddish claval margins. Leg spine apices black. Claws dark brown.

Male genitalia ( Figs 19–27 ). Anal tube as wide as long (in lateral view), nearly truncate apically (in dorsal view) ( Figs 19, 20 ). Anal column short. Pygofer wide, elongate vertically (in lateral view), with widely concave medially ventral margin (in ventral view) ( Figs 19, 21 ). Hind margins of pygofer with large triangular­shaped process below the anal tube ( Fig. 19 ). Aedeagus strongly curved (in lateral view), with denticles dorso­laterally and with pointed apical bifurcation (in ventral view) ( Figs 22, 23 ). Style with wide plate and long capitulum ( Figs 24, 25 ) and with large and rounded lateral process below the capitulum ( Figs 26, 27 ).

Female genitalia ( Figs 13 , 28–31 ). Sternite VII with sharply concave medially hind margin, fused endogonocoxal lobes furcating apically. Anal tube short.

Total length: males – 8.0–9.0 mm, females – 9.0–10.0 mm.

4th instar larva. It was illustrated by EMELJANOV (1999, Fig. 17 ) as Symplana sp.

Structure. Metope with seven (3 + 4) sensory pits in two rows above the eye and three pits along sublateral carina in front the eye at each side. Median carina of metope reaching metopoclypeal suture only. Rostrum reaching hind coxae. Coryphe long, more than three times as long medially as wide between the eyes. Disc of pronotum with five (4 + 1) pits on each side. Each paranotal lobe of pronotum with a single pit at basal margin. Anterior wing pads of mesothorax each with four (3 +1) pits. Posterior wing pads of methatorax each with two sensory pits. Hind tibia with a single lateral spine above its middle and with six spines apically. Tergites IV–VI each with four (two on each side) pits near to its posterior margins. Tergite VII with four (two on each side) pits near to its posterior margin, one pit in each hind corner dorsally and one pit in each hind corner ventrally (not visible in dorsal view). Tergite VIII with two pits dorsally and one pit ventrally (not visible in dorsal view) in each hind corner. Segment IX with four pits—two dorsal and two ventral ones. Metatarsomeres with two segments, first one with two latero­apical and a single intermediate spines. Body length: 4.0 mm.

Etymology. The species is named in honour of the well­known French botanist Dr. Maurice Schmid (1922–2018), who spent his professional life studying Indo­Chinese vegetation and soils. Our meetings with Maurice in his latest lifetime gave me and my family great pleasure.

Note. The species is swept from bamboo in dry Dipterocarpus forest on a water reservoir bank ( Figs 69, 70 ).

Comparison. It is closely related to S. longicephala Chou, Yuan et Wang, 1994 by furcated apically fused endogonocoxal lobes ( ZHANG et al. 2020, Fig. 39m ).
