Yu, Xiaofei & Yang, Maofa, 2014, Four new species of Alebroides Matsumura (Hemiptera: Cicadellidae: Typhlocybinae) from China, Zootaxa 3780 (2), pp. 248-262 : 249

A. chiasmaticus Yu & Yang , sp. nov.

( Figs 14–25 )

Type material. Holotype, ♂, Mt. Daming, Guangxi, 14–17. May. 2011, coll. Xiaofei Yu. Paratype, ♂, Mt. Daming, Guangxi, 14–17. May. 2011, coll. Rong Huang.

Length: ♂ 4.6mm.

Crown yellowish ( Fig 14 ). Coronal suture brownish, not reaching apex of crown ( Fig 14 ). Face yellowish ( Fig 15 ). Pronotum semitransparent posteriorly ( Fig 14 ). Scutellum yellowish except apically dark ( Fig 14 ). Forewing hoary, semitransparent; hindwing hyaline ( Fig 14 ). Abdomen yellowish. Legs hoary except claws brownish.

Male ventral abdominal apodemes not reaching third segment. Male pygofer triangular, apical margin with setae; ventral pygofer appendage distinctly exceeding pygofer, thick, straight, pubescent, apex acuminate; dorsal bridge less than 1/3 length of pygofer, lateral lobes poorly developed ( Figs 17, 18, 19 ). Subgenital plates tapering, with 2 rows of 21 macrosetae, 3 rows of ca.45 feeble microsetae, ca.18 marginal setae and 6 basal group macrosetae ( Fig 20 ). Paramere elongate, apex falcate, subapex with setae, with slight swelling 3/4 of distance from base ( Fig 21 ). Aedeagus expanded from base to 2/3 length in ventral view, distal 1/3 abruptly narrower, with two long crossed falcate processes arising from preatrium ( Figs 22, 23 ). Anal tube process elongate, apex branched as in fig 24. Connective lamellate, approximately as long as wide, without distinct posterior emargination ( Fig 25 ).

Etymology. The new species name alludes to aedeagal process crossed in ventral view, the Latin word “ chiasmaticus ” means crossed.

Remarks. The new speices is similar to A. sohii Thapa , but differs in having the aedeagal basal process branched, sinuate in lateral view and crossed in ventral view ( Figs 22, 23 ), the shaft unexpanded in lateral view ( Fig 23 ) and the male pygofer appendage pubescent ( Figs 18, 19 ).
