Luo, Qiang, Yang, Lin & Chen, Xiang-Sheng, 2018, Review of the bamboo-feeding leafhopper genus Neomohunia, with descriptions of two new species from China (Hemiptera, Cicadellidae, Deltocephalinae, Mukariini), ZooKeys 790, pp. 101-113 : 103

Neomohunia longispina sp. n. Figs 1-13, 37-39, 48

Diagnosis.

The salient characteristics of the new species include the pygofer in profile with pair of small unequal spines arising directly from posteroventral margin (Figs 8-9), and the aedeagus with its shaft slightly laterally compressed, with three spinous processes arising from base of long preatrium (Figs 11-13).

Description.

Measurements. Body length (including forewing): male 5.11-5.67 mm (7 specimens); female 5.92-5.98 mm (4 specimens).

Coloration. Crown and pronotum pale yellow to white, with a longitudinal medial bright red band widening from apex of head to base of pronotum (Figs 1, 3). Eyes yellowish brown to brown (Figs 2, 4). Face yellow, anteclypeus, and lorum yellowish white (Figure 5). Mesoscutum and scutellum brown (Figs 1, 3). Forewing orange red to red, clavus with a longitudinal broad brown stripe along lateral margin (Figs 1, 2, 7); brachial cell with a bright red stripe along inner margin (Figs 1, 2, 7); brachial cell at apex, inner anteapical cells near m-cu3, costal margin near middle, outer apical cell near R2+3 with dark brown markings (Figs 1, 2, 7); outer and central anteapical cells with a pellucid spot at apex, inner apical cell slightly brown (Figs 1, 2).

Head and thorax. External features as in generic description with following proportions. Crown slightly shorter medially than width between eyes (0.68:1) (Figs 1, 3); coronal suture shorter than half of length of crown in median line (0.35:1) (Figs 1, 3). Pronotum slightly wider than head including eyes (1.19:1) and about 2 times longer than head (1.85: 1) (Figs 1, 3). Mesoscutum and scutellum together distinctly shorter than pronotum (0.70:1) (Figure 3). Forewing about 3 times longer than widest part (2.75: 1) (Figs 1, 2).

Male genitalia. Pygofer in profile with pair of small unequal spines arising directly from posteroventral margin (Figs 8-9). Aedeagus with shaft slightly laterally compressed, gonopore subapical on dorsal surface; with three spinous processes arising from base of long preatrium, two shorter lateral processes directed obliquely outwards and a longer medial process curving ventrally from base at its articulation with connective then curved dorsally and tapered to acute apex (Figs 11-13).

Female genitalia. Sternite VII (Figure 37) with anterior margin slightly concave; lateral margin slightly expanded at basal 1/3; posterior margin strongly convex and with acute median tooth. Ovipositor as in generic description.

Material examined.

Holotype: ♂, China: Guizhou Province, Xishui County, Sanba Nature Reserve (28°20'N, 106°12'E), 27 September 2017, Bin Yan and Nian Gong (IEGU); paratypes: 4♂♂3♀♀, same data as holotype (IEGU); 2♂♂1♀, same data as holotype (NHMUK).

Host plant.

Bamboo (Figure 48).

Distribution.

China (Guizhou Province).

Remarks.

This species can be distinguished from other species mainly by the unusual position of the aedeagal processes at the base of the preatrium (Figs 11-13).

Etymology.

The name is derived from prefix longi and the Latin word spina, which refers to the long medial process of the aedeagus.
