Three new species in the leafhopper genus Angustuma (Hemiptera: Cicadellidae: Evacanthinae) from Thailand Author Wang, Yang Author Zhang, Yalin text Zootaxa 2014 3893 4 587 594 journal article 10.11646/zootaxa.3893.4.8 0a404643-b1ad-422a-b274-96c8c472b7bc 1175-5326 227638 F7114368-60C9-4DAC-A718-3148AE31A39E Angustuma basinigra sp. nov. ( Figs 1–10 ) Description. Body length (including forewing): ♂, 5.9–6.2 mm . Dorsum ( Fig. 1 ) yellow to orange, marked with black stripes and patches. Crown ( Figs 1, 3 ) with irregular black patch between ocelli, extending to ocelli. Frontoclypeus ( Fig. 4 ) with median longitudinal carina blackish ochreous, marking enlarged to a small rounded spot at apex, oblique lateral striations distinct. Lorum ( Fig. 4 ) black at base. Pronotum ( Figs 1, 3 ) orange, with narrow black band along posterior margin. Forewing ( Figs 1, 2 ) with broad black stripe along claval suture and Mvein respectively, apex gray. Aedeagal ( Fig. 7 ) ventral apophysis in lateral view approximately triangular, posterior margin slightly concave preapically. Style ( Fig. 9 ) apophysis in ventral view F-shaped. Connective ( Fig. 9 ) stem in ventral view with lateral tooth at middle. Subgenital plate ( Fig. 10 ) elongate, expanded medially, macrosetae irregularly distributed, rows of elongate setae near interior submargin. Type material. Holotype : ♂ ( QSBG ), THAILAND : Chiang Mai Doi Chiangdao NP Headquarter, 19°24.278′N 98°55.311′E , 491 m , Pan trap, 5–6.VIII.2007 , S. Jugsu & A. Watwanich. Paratypes : 2♂♂ ( NWAFU & INHS ), same data as holotype . Remarks. This species is very similar to A. jinghongensis ( Li & Li, 2011 ) externally, but it can be distinguished from the latter by: 1) lorum ( Fig. 4 ) black at base, pale in latter; 2) each forewing ( Figs 1, 2 ) with 2 thick stripes, latter with 4 thin stripes; 3) aedeagal ( Fig. 7 ) ventral apophysis in lateral view smaller than in latter, shape also different. Etymology. The specific epithet, a combination of “basis” meaning basal, and “nigra” meaning black, refers to the lorum being black at base in these insects.
