Wang, Yang & Zhang, Yalin, 2014, Three new species in the leafhopper genus Angustuma (Hemiptera: Cicadellidae: Evacanthinae) from Thailand, Zootaxa 3893 (4), pp. 587-594 : 593

Angustuma flavimacula sp. nov.

( Figs 21–31 )

Description. Body length (including forewing): ♂, 7.2 mm; ♀, 7.9 mm. Dorsum ( Fig. 21 ) blackish ochreous, marked with off-white and yellow spots. Crown ( Figs 21, 23 ) with four irregular off-white spots on lateral, anterior and posterior margin. Face ( Fig. 24 ) with median longitudinal carina blackish ochreous, gradually narrowing from apex to base, with pair of narrow blackish ochreous maculae just mesad of eyes. Lorum ( Fig. 4 ) blackish ochreous. Gena ( Fig. 24 ) with blackish ochreous stripes on the middle portion. Pronotum ( Figs 21, 23 ) blackish ochreous, marked with off-white on middle lateral margin. Forewing ( Figs 21, 22 ) with large yellow spots on clavus and lateral margin respectively.

Aedeagal ( Fig. 28 ) ventral apophysis in lateral view finlike, apex pointed. Style ( Fig. 29 ) apophysis in ventral view elongate and acuminate. Connective ( Fig. 27 ) stem broadened near apex with pair of short retrorse preapical spines. Subgenital plate ( Fig. 30 ) knifelike, broad in middle portion, macrosetae in single row through most of length, row of elongate setae near interior submargin.

Female and male ( Fig. 25 ) are slightly dimorphic in coloration and shape of marks. Female seventh sternite ( Fig. 31 ) longer than the sixth sternite, posterior margin well produced laterally and almost flat medially.

Type material. Holotype: ♂ ( QSBG), THAILAND: Chiang Mai Doi Phahompok NP Doi phaluang, 20°1.06′N 99°9.581′E, 1449 m, Malaise trap, 20–27.VII.2007, Wongchai P. Paratype: 1♀ ( NWAFU), same data as holotype.

Remarks. This species is easy distinguished from other species of Angustuma Xing & Li, 2013 by the dorsal coloration and marks. Its male genitalia are very similar to those of Angustuma nigricarina ( Li, 1986) , but the shapes of the aedeagal shaft and ventral apophysis ( Fig. 28 ) in lateral view are different.

Etymology. The specific epithet, a combination of “flavus”, meaning yellow, and “macula”, meaning spot, refers to the forewing having a large yellow spot on the lateral margin.
