Niranjana, G. N., Meshram, Naresh M. & Nikoshe, Akash Prakash, 2020, Four new species of the genus Pseudosubhimalus (Hemiptera: Cicadellidae) from the Indian subcontinent, Zootaxa 4894 (2), pp. 269-277 : 270-272

1. Pseudosubhimalus asymmetricus sp. nov. Meshram & Niranjana

( Figs. 1-2, 9, 13 & 17-22 )

Male: Brown, crown pronotum and scutellum marked with irregular dark brown spots. Face black with irregular paired transverse yellow stripes. Compound eyes pale yellow with reddish tinge, ocelli orange. Forewings dark brown; veins pale, irregularly bordered with dark brown ( Fig. 2 ). Head including eyes 1.1x width of pronotum ( Fig. 13 ), in dorsal view obliquely rounded in front, crown length 0.35x width across eyes; face length 0.87x width of face. Ocelli near anterior margin of crown, distance between eye and ocellus equal to diameter of ocellus ( Fig. 9 ). Pronotum 0.5x as long as width and 0.8x length of scutellum ( Fig. 13 ).

Male Genitalia: Pygofer 1.5x longer than broad ( Fig. 17 ), with long setae on posterior half, dorsal and ventral posterior margin without serrations. Valve triangular ( Fig. 18 ), subgenital plate longer than wide, gradually narrowed posteriorly, lateral margin with 9-10 uniseriate macrosetae, apex with long hair like setae ( Fig. 18 ). Style ( Fig. 19 ) broad at base with well-developed preapical lobe, apophysis long, slender, with blunt apex, 1/3 rd of total style length. Connective V-shaped ( Fig. 22 ); stem narrowed, 0.8x length of arms. Aedeagus, in lateral view ( Fig. 20 ), broadly C-shaped, shaft uniformly broad throughout its length, apex minutely serrated acute, sinuate and moderately broad at base. In dorsal view acuminate apically with two asymmetrical subapical processes ( Fig. 21 ). Gonopore subapical at base of processes.

Measurement (mm): Total Length: 7.1; Crown Length: 0.5; Width of Head: 1.9; Width of Pronotum: 2.4.

Etymology: Species name asymmetricus alludes to asymmetrical subapical processes on aedeagus.

Type material: Holotype: 1³ INDIA: Himachal Pradesh, Dalang maidan, (32.1297° N, 77.1241° E and 3300 MSL) 23.ix.2016, sweep net Coll., Niranjana ( NPC).

Remarks: This species is closely associated with P. trilobata, Meshram & Niranjana (2019) in certain characters but differs in having, aedeagus C-shaped, shaft uniformly broad throughout its length, with serrated acute apex; subapical processes asymmetrical.
