Tang, Jiu & Zhang, Yalin, 2021, Review of the leafhopper genus Hatigoria Distant with one new species (Hemiptera: Cicadellidae: Hylicinae), Zootaxa 5005 (3), pp. 358-366 : 362-366

Hatigoria longistylia n. sp.

( Fig. 3 )

Length: ♂ 16.2–16.6 mm.

External morphology. Body ( Fig. 3A–D ) usually yellow brown. Crown ( Fig. 3C ) more than 3.0x longer than wide; anterior process slightly curved dorsad with margins parallel in lateral view, with lateral ridge simple and legible, unbranched; ocelli not very outstanding, median longitudinal carina strong but absent near base, apical half slightly recurved upward and sword-shaped in lateral view. Face ( Fig. 3D ) with clypeal sulcus slightly arcuate, anteclypeus base with one transverse carina, one indistinct median longitudinal carina below transverse carina, apex hardly surpassing lower margin of gena and feebly truncate, antennal ridges moderately developed and declinate. Pronotum ( Fig. 3A ) with dorsal surface mainly covered with black setae and lateral surface covered with lightcolored setae, anterior margin somewhat arcuate, depressed anterolaterally, lateral margins not ridged and a little concave, obviously longer than anterior margin. Exposed part of mesonotum ( Fig. 3A ) about as long as scutellum, scutellum slightly swollen distad of scutoscutellar sulcus. Abdomen with irregular yellow patches on 4th to 6th or even 7th tergites laterally. Hind femur macrosetal formula 2+1+0, with ca. 10, 11–12 and 14–18 setae in rows AD, PD, AV respectively; tarsomere I without row of plantar setae, pecten with 11 platellae.

Male genitalia. Pygofer ( Figs. 3E–G ) with dorsal outer margins somewhat convex; subgenital plate ( Fig. 3J ) nearly as long as pygofer, outer margins moderately evenly convex, apex somewhat round and nearly as broad as base; ventral appendages about as long as subgenital plate, with basal 1/2 part very broad, terminal 1/2 part slender and strongly curved mesad, with elongate spine on posterior corner; lateral margins of connective ( Fig. 3H ) slightly vertically expanded into keeled process and touching each other medially in dorsal view, apex of vertical process broader than rest and apically acute and backward curved; style about 3.0x longer than connective, apophysis with base broad and terminus tapering, surpassing apex of connective, with about six setae at apex; aedeagal shaft ( Figs. 3I, K ) tubular, with a few tiny transverse wrinkles on dorsal surface, gonopore at apex.

Material examined. Holotype ♂: Vientiane Prov., Laos, 15.V.1966, Light trap ( BPBM) ; Paratype 1♂: Daluo Town , Yunnan Province, China, 7.V.2009, Lei Zhang ( NWAFU) .

Distribution. China, Laos.

Etymology. This new species epithet is from Latin, “ longistylia ” referring to its elongate head process and long branch of the ventral pygofer appendage.

Notes. This species resembles Hatigoria praeiens in external morphology but may be distinguished by the following characteristics: 1) head process longer and only slightly curved upward (process of H. praeiens shorter and obviously curved upward); 2) aedeagal shaft tubular with few tiny wrinkles on dorsal surface (shaft of H. praeiens with base sunken and numerous transverse wrinkles on dorsal surface); and 3) subgenital plate apex somewhat round and broad (plate apex of H. praeiens moderately acute and narrow).
