Xing, Jichun & Li, Zizhong, 2014, Two new species of the genus Abrus Dai & Zhang, 2002 (Hemiptera, Cicadellidae, Deltocephalinae) from China, ZooKeys 419, pp. 103-109 : 105-106

Taxon classification Animalia Hemiptera Cicadellidae

Abrus expansivus Xing & Li sp. n. Figs 12-22

Description.

External features resemble as Abrus damingshanensis sp. n., but color light yellow and body slightly small.

Male genitalia. Male pygofer side elongate with many macrosetae posteriorly and a few at midventral margin; posterior margin lobe elongate and with a long membranous process at inner apex (Fig. 16). Valve subtriangular with anterior margin concaved and posterior margin strongly produced medially (Fig. 17). Subgenital plate broad and short, outer margin rounded, with many macrosetae on lateral margin (Fig. 18). Aedeagus with broad and flat basal projection from dorsal margin, deeply concave at dorsal margin, the basal projection without processes; aedeagal shaft slightly shorter than basal projection, with a pair of slender apical processes and its length equal to aedeagal shaft, gonopore apical (Figs 19, 20). Connective Y–shaped, stem robust, arms well developed, articulated with the aedeagus (Fig. 21). Style long, broad at base, narrow at middle, apex slightly widening (Fig. 22).

Measurement.

Length (including tegmen): ♂, 8.1 mm.

Type material.

Holotype ♂, China: Guizhou Province, Dushan County, 16 July 2012, coll. Qiongzhang Song (GUGC).

Diagnosis.

This new species is very similar to Abrus brevis Dai & Zhang, 2002 in aedeagal shaft with a pair of long apical appendages, but can be distinguished from the latter by the aedeagal shaft longer than half length of basal projection; aedeagal shaft with apical processes located medially in lateral view and its length equal to aedeagal shaft; the apical process of style wide and flat; and the subgenital plate narrow apically.

Etymology.

The new species name is derived from the Latin word “expansivus”, referring to the apical process of style wide and expand.
