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 View FIGURES 65–77 ). Connective short with lateral arms widely separated ( Fig. 73 View FIGURES 65–77 ). Paramere slender with four sensory pores on caudal part ( Fig. 74 View FIGURES 65–77 ). 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 View FIGURES 65–77 ).

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 View FIGURES 65–77 ).
