Hatigoria zhangi sp. nov.

Figs 5A, B , 9A , 12A , 13D–F , 15B , 17A–H

Diagnosis. Uniformly dark brown or brown. Anterior projection of crown forming obtuse angle with rest of crown in lateral view. Pronotum 1.4× as wide as long medially, posteriorly almost 2× as wide as anteriorly behind eyes. Mesonotum longer than pronotum but shorter than crown, not gibbous. Male pygofer ventral process with inner fork 2.5× as long as outer fork. Aedeagal shaft dorsal surface with a few transverse rugae near basal region.

Description. Uniformly brown to dark brown. Crown 4.5× as long as interocular distance, anterior projection, in lateral view, of uniform width, sword-like disposed at an obtuse angle to rest of crown. Pronotum with depression on either side of median line in anterior half, disc transversely rugose punctate, 1.4 × as wide as long medially, posteriorly almost 2× as wide as anteriorly behind eyes. Mesonotum 1.4× longer than pronotum but shorter (0.7× as long as crown) than crown, not gibbous.

Male genitalia. Pygofer elongate more than 2× as long as height in lateral view, ventral process bifid apically, with inner fork 2.5× as long as inner fork, curved mesally then anteriorly, overlapping with its counterpart medially. Subgenital plate elongate, each narrowed apically, more than 3× as long as greatest width. Style with anterior part 2× as long as apophysis, apophysis long reaching apex of connective. Connective more or less X-shaped, posterior end wider than anterior end. Aedeagus as in H. praeiens but shaft with a fewer transverse rugae on dorsal surface proximally, in dorsal view and slightly narrowed distally, gonopore apical.

Measurements. Male 16.6–16.7 mm long, 1.9 mm wide across eyes and 3.3 mm wide across posterolateral angles of pronotum.

Material examined. HOLOTYPE ♁, INDIA: Arunachal Pradesh: Khonsa , 26.99290 N 25.50140 E, 11.vii.2018, host: grasses, Sweep net, Stuti ( UASB) . Paratype 1♁, data as in holotype ( NPC) .

Etymology. The species is named in honour of Dr. Yalin Zhang, Northwest A&F University, Yangling, China, for his invaluable contributions to the taxonomy of the Oriental Auchenorrhyncha.

Remarks. H. zhangi is very similar to H. longistyla Tang & Zhang from Laos in having a similarly shaped ventral pygofer process and aedeagal shaft. However, the new species differs in the shape of the crown in lateral view, the anteriorly directed inner fork of the ventral pygofer process (mesally directed in H. longistyla ), the shape of the lateral margin of the style apophysis (straight in H. zhangi but concavely excavated in H. longistyla ) and different curvature and proportions of the aedeagus. The subgenital plates in H. zhangi are apically narrowed with less convex outer margin whereas in H. longistyla they are widened distally with convex lateral margins.
