Concavocorona supercilia, Wang, Yang & Zhang, Yalin, 2014

Wang, Yang & Zhang, Yalin, 2014, Concavocorona, a new genus of the leafhopper subfamily Evacanthinae (Hemiptera: Cicadellidae), with description of a new species, Zootaxa 3794 (4), pp. 587-592 : 591

Concavocorona supercilia sp. n.

( Figs 1–10 , 21)

Description. Body length (including forewing): ♂, 8.1–8.3 mm; ♀, 8.5–8.6 mm. The transverse beige patch ( Fig. 4 ) on frontoclypeus large, taking up more than 1/3 area of frontoclypeus, and enclosing a pair of blackish ochreous browlike spots anterad of eyes.

Ventral process of pygofer ( Figs 8, 9 ) silghtly sinuate. Aedeagal ( Fig. 6 ) ventral process in lateral view approximately triangular. Style ( Fig. 7 ), the apodeme apex straight in ventral view, the apophysis is of uniform width and only near apex abruptly narrows to slender pointed process. Other characteristics as shown in Figs 1–10 , 21.

Type material. THAILAND: Holotype ♂ ( QSBG), Chiang Mai Doi Phahompok NP Doi phaluang, 1149 m, malaise trap, 07–14. II. 2008, Seeson. K. Paratypes: 1♀ ( NWAFU), same data as holotype; 1♂ ( NWAFU), same data as holotype except collected on 21–28. II. 2008; 1♀ ( UIUC), ChiangMai Doi Phahompok NP Doi kewom 1/ montane forest, 2174m, malaise trap, 07–14. II. 2008, Seeson. K.

Remarks. This species is very similar to C. abbreviata (Jacobi) , n. comb. externally, but it can be distinguished from the latter by: 1) body larger; 2) anterior margin of crown less sharp ( Figs 3 , 13 ); 3) transverse beige patch ( Fig. 4 ) on frontoclypeus large and enclosing pair of blackish ochreous browlike spots ( Fig. 14 ); 4) apophysis of style of uniform width and only near apex abruptly narrowed to slender pointed process ( Fig. 7 ); 5) style apodeme apex straight in ventral view ( Fig. 7 ); 6) aedeagal ventral process approximately triangular in lateral view ( Fig. 6 ).

The specimens examined were previously preserved in alcohol and subsequently point mounted, which may account for some of the differences in coloration noted between this species and C. abbreviata .

Etymology. The specific name refers to the browlike spots of these insects.
