Bhatiahamus, Lu, Lin & Zhang, Yalin, 2014

Lu, Lin & Zhang, Yalin, 2014, A new leafhopper genus Bhatiahamus (Hemiptera: Cicadellidae: Deltocephalinae) from China with description of a new species and a new combination, Zootaxa 3835 (3), pp. 371-375 : 371-372

Genus Bhatiahamus gen. nov.

Type species: Bhatiahamus flabellata ( Shang & Shen), 2006

Description. Body yellowish brown. Fore margin of head with 1–2 dark brown bands between eyes. Pronotum with brown irrorations. Forewing hyaline smoky brown with a brown spot at apex of claval veins. Head slightly broader than pronotum with a few transverse carinae or striations on anterior margin. Vertex short, slightly longer medially than next to eyes; transversely depressed subapically. Ocelli situated on fore margin and a little distant from eyes, with a transverse ridge between ocelli. Face broader than length; antenna longer than half body length, located at front top corner of eye; antennal pit deep and expanded onto frontoclypeus; frontoclypeus with median area slightly swollen; anteclypeus narrowed medially with base broader than apex; lora large. Pronotum with sides short. Scutellum about same length as pronotum. Front femur with anteroventral (AV1) setae long, intercalary (IC) row with about 13 setae; AM1 seta large, situated near apex; AV setae absent. Fore tibia with setal formula 1+4. Hind femur apical setal formula 2+2+1. Forewing with three subapical cells and the first subapical cell open; clavus with crossvein between inner claval vein and claval suture.

Male genitalia with pygofer side broad basally, tapering to rounded or acute apex, with numerous distal macrosetae. Xth segment with well developed apical process on each side. Subgenital plate long with digitate apex; with short fine setae ventrally and along lateral margin, without macrosetae. Style with apical process short, produced laterally rostriform, with fine sculpture; lateral lobe slight to prominent; outer basal arm robust, inner basal arm short. Connective short, H-shaped with stem shorter than arms. Additional sclerite articulated between connective and aedeagus. Aedeagus with lobed area of dorsal apodeme well developed; shaft simple, cylindrical, evenly curved dorsally or sinuate in lateral view, with pair of apical processes or triangular shaped process on each side apically; gonopore subapical on ventral surface.

Distribution. China (Henan, Guangxi, Sichuan, Yunnan).

Etymology. The genus name refers to the hooked anal tube and overall similarity to the genus Bhatia .

Remarks. The genus is similar to Bhatia Distant based on the additional sclerite articulated between the connective and aedeagus ( Figs. 1 M, 2K) but can be distinguished by the character of the anal hook. Bhatiahamus resembles Roxasellana Zhang in the shape of the dorsoatrium of the aedeagus but differs in the characteristics of the connective and the additional sclerite ( Fig. 2 K). Bhatiahamus is also similar to the genus Isaca Walker in having an anal tube process, but can differs in having a pair of anal hooks in the former ( Figs. 1 F, 2L), rather than a single process as in the latter.
