Hishimonus adi, Singaravel & Singaravel, 2020

Singaravel, M. & Singaravel, M., 2020, A new species of the genus Hishimonus Ishihara, 1953 (Hemiptera: Cicadellidae Deltocephalinae) with a new record from India, Zootaxa 4750 (1), pp. 131-137 : 134-135

Hishimonus adi sp. nov.

(Figs 1-9)

Head and pronotum yellow with green tinge (Fig. 1). Scutellum light brown with black mottling. Vertex with two small light brown spots near apex and median line running halfway from the posterior margin to apex. Pronotum greenish brown, mottled with dark brown patches. Face pale yellow with transverse brown striations (Fig. 3). Forewings creamy white with pale brown spots between veins, distal half of apical cells more darkly mottled; median spot well defined with discontinuous dark brown border on the anterior half margin (Figs 1–2).

FIGS 1–10. Hishimonus adi . sp. nov.1.Habitus dorsal; 2. Habitus lateral; 3. Face; 4. Pygofer; 5. Subgenital plate; 6. Aedeagus lateral; 7. Aedeagus dorsal; 8. Style; 9. Connective

Male genitalia: Pygofer (Fig. 4) in lateral view longer than wide, posterior margin conically rounded, macrosetae confined to posterior lobe. Valve wider than long (Fig. 5). Subgenital plates rounded at base, terminal fingerlike process about 3.4 times shorter than total length, long hairlike setae along lateral margin, terminal process with short microsetae (Fig. 5). Style approximately 3.9x as long as wide at base; preapical lobe prominent with few hair like setae, apophysis digitate, 1/3 rd of the total length (Fig. 8). Stem of connective (Fig. 9) as long as arms.Aedeagus with shaft in lateral view (Fig. 6) broad basally, narrowed apically, with lobe like median process; two shafts in posterior view (Fig. 7) widely splayed, broad in middle, narrower at base and apex, with subapical lamellate expansion along lateral margin, gonopore apical.

Measurements. Male 3.633mm long, 1.19mm wide across eyes.

Type material. HOLOTYPE ♂, India: Arunachal Pradesh: Pasighat 173m, 28°04ʹ31ʺN 95°19ʹ19ʺE, 3.vii.2018, at light, Stuti & Tahseen R. Hashmi ( NPC).

Etymology. This new species name, a noun, is the name of the group of indigenous “ Adi” people inhabiting the type locality.

Remarks. Hishimonus adi sp. nov. closely resembles H. phycitis (Distant) and H. diffractus Dai, Fletcher & Zhang but differs in having the aedeagal shaft: with lobe like median process in lateral view which is absent (in H. phycitis ) or sharp thorn like on inner margin (in H. diffractus ), with subapical lateral lamellate expansion rather than apical lamellation (in H. phycitis ) or no lamellation (in H. diffractus ) and with apical gonopore opening whereas opens subapically on posterior surface in the later two species.
