Wang, Xiu-Dan, Dietrich, Christopher H. & Zhang, Ya-Lin, 2018, Four new species of tribe Coelidiini (Hemiptera: Cicadellidae: Coelidiinae) from the Afrotropical Region, Zootaxa 4415 (3), pp. 591-600 : 595

Brasura piscinura sp. nov.

( Figs 2, 4, 6 , 22–28 )

Description. Measurements. Male body length 10.05 mm; head width 2.61 mm; crown length×width: 0.88× 1.06 mm; eye width 0.89 mm; frontoclypeus length 2.18 mm; clypellus length 1.01 mm; pronotum length×width 1.05× 3.11 mm; mesonotum+scutellum length 1.63 mm. Female unknown.

Crown light brown with a pair of darker maculae mesad of posteromedial eye corners ( Fig. 2 ). Pronotum and mesonotum piceous with light brown granules; scutellum brown ( Fig. 2 ). Elytra fuscous with light brown spots along veins, surface densely covered with numerous tiny pale spots ( Figs 2, 6 ). Ratio of crown, pronotum and mesonotum midline is about 1:1.19:1.85.

Male genitalia. Pygofer without processes, broad and swollen caudodorsally ( Fig. 23 ). Segment X broad, lateral margins conveX ( Fig. 22 ). Aedeagus moderately narrow with few short spines subbasally; distal half of shaft eXpanded, with row of numerous setiform spines on each side, strongly constricted subapically with apical section recurved to left; apeX widened and concave distally with serrated margin; gonopore lateral at midlength of shaft ( Figs 24–25 ). Dorsal connective stick-like ( Fig. 25 ). Style very short, attenuated distally with blunt apeX ( Fig. 26 ). Connective asymmetrical with triangular base, anterior arms long and curved, apeX recurved ( Fig. 27 ). Subgenital plate slender, outer margin slightly conveX, rounded apically with fine spines ( Fig. 28 ).

Material examined. Holotype: male, Republic of the Congo: Department Pool , 3°06.020′S 15°31.440′E, 330m, 26 Aug. 2008, coll. M. Braet and M. Sharkey.

Etymology. The new species name is a Latin word, meaning fish tail, referring to the shape of the apeX of the aedeagus.

Remarks. This species resembles B. peditata Nielson but differs in having a dense row of spines on both sides of the aedeagal shaft and the apeX of the aedeagus fish tail shaped.
