Dai, Wu, Fletcher, Murray J. & Zhang, Yalin, 2013, First records of the genus Hishimonus Ishihara from Thailand (Hemiptera: Cicadellidae: Deltocephalinae: Opsiini) including description of three new species, Zootaxa 3670 (3), pp. 301-316 : 311

Hishimonus pallidus sp.nov.

( Figs. 2 B, 2E, 7A–F)

Holotype, male, Chaiyaphum Tat Tone NP, forest fire protection station, 16o0.809’N 102o1.335’E, 195m, malaise trap 3–9.vi.2006, Tawit Jaruphan & Orawan Budsawong, T2534 ( QSBG).

Description. Evenly pale yellow with slightly darker mottling. Vertex with transverse furrow behind apex with bears two brown elongate spots. Tegmen evenly testaceous with scattered darker minute speckling, becoming darker and more dense apically.

Male genitalia. Subgenital plates broad triangular, tapering to narrow apical fingerlike process, with long hair setae along outer margins in addition to uniseriate stout marginal macrosetae. Paramere with apical process slightly truncate. Aedeagus in posterior view with shafts broadly divergent, curved slightly upwards with lateral process fused laterally to shaft almost to level with gonopore than separated into elongate pointed processes extending dorsally to acute apex, slightly incurved over free portion. Shaft extended beyond gonopore to form narrow apical processes slightly exceeding apex of lateral process. Aedeagus in lateral view slightly broader at one third length than at base, then narrowing to apex, apical process of aedeagal shaft curved anteriorly, lateral process almost straight.

Etymology. The species name reflects the pallid colouring of this species.

Comments. This is the only species so far recorded in Thailand in which the dorsal brown patch on the hind margin of the forewing appears to be lacking although the paucity of available material is insufficient to confirm this. It is distinctive in the juxtaposition of the apical aedeagal process with the apex of the lateral process on each shaft. It shows close similarity with H. dividens Knight from Sri Lanka.
