Zhou, Juan, Zhang, Yalin & Huang, Min, 2021, First records of the Oriental Eurhadina (Singhardina) robusta species group from China with descriptions of five new species (Hemiptera: Cicadellidae: Typhlocybinae), Zootaxa 5061 (3), pp. 510-522 : 519

Eurhadina (Singhardina) furca Zhang et Huang sp. nov.

( Figs 65–77 )

Body form and color patterns very similar to E. (S.) dissimilis sp. nov., but somewhat shorter.

Male genitalia: Upper lobe of pygofer side tuberculated and serrated with several rigid microsetae distally, disc of lower lobe with several fine microsetae ( Figs 69, 70 ). Subgenital plate with one long macroseta near basal 1/3; three short macrosetae longitudinally near apical 1/3; several fine microsetae near subapex and one rigid microseta on apex ( Figs 71, 72 ). Connective short with lateral arms widely separated ( Fig. 73 ). Paramere slender with four sensory pores on caudal part ( Fig. 74 ). Aedeagus with developed dorsoatrium; aedeagal shaft slim and slightly curved in lateral view with two pairs of slim and curved apical appendages; dorsal and ventral appendages arched towards outside and ventral appendages below dorsal ones basally in dorsal view; ventral appendages with a short protrusion near basal 1/3 and dorsal appendages bifurcate apically ( Figs 75–77 ).

Specimens examined. Holotype: ♂, China, Yunnan Prov., Yaoqu , 3 June 2009, coll. Wei Cui. Paratypes: 28 ♂, China, Yunnan Prov., Yaoqu , 5 September 2010, coll. Juan Han.

Measurement. Length of male 3.13–3.36 mm (including wing).

Etymology. The specific epithet is derived from the Latin word “ furca ” referring to aedeagal shaft with dorsal appendages bifurcate apically that is unique in this species group.

Remarks. This new species resembles E. (S.) dissimilis sp. nov. in external characters, but differs in having the dorsal appendages of the aedeagal shaft apically bifurcated and ventral appendages with only a short protrusion near the basal 1/3 ( Figs 75–77 ).
