Eurhadina (Singhardina) flatilis Zhang et Huang View in CoL sp. nov.

( Figs 39–51 View FIGURES 39–51 )

Body creamy. Face sordid white ( Fig. 42 View FIGURES 39–51 ). Central part of crown brownish with four orange patches. Pronotum with two pairs of round patches symmetrically anteriorly, central pair patches orange and lateral pair patches yellowish; yellowish pale fascia posteriorly; basal triangles yellowish; scutellum with two small dark brownish patches laterally and two yellowish marks on sides of scutellum ( Figs 39, 41 View FIGURES 39–51 ). Forewing pale white, with one oblique strip at basal part of corium area; posterior margin of clavus with one semi-cycle yellowish pale patch centrally and a brown spot distally; ochre oblique strip along claval furrow; brochosome area with a brownish patch on costal margin and one oblique strip along distal margin; one oblique strip on ScP+RA; a brown spot on apical 1/3 of RP; 1st apical cell and its adjoining area covered with irregular brownish patches ( Figs 39, 40 View FIGURES 39–51 ).

Male genitalia: Upper lobe of pygofer side strongly pigmented and serrated distally; lower lobe with several rigid microsetae and fine microsetae distally ( Figs 43, 44 View FIGURES 39–51 ). Subgenital plate with one long macroseta near basal 1/3; several short microsetae extend from basal part to subapex and two rigid microsetae on apex ( Figs 45, 46 View FIGURES 39–51 ). Connective broad with lateral arms widely separated ( Fig. 47 View FIGURES 39–51 ). Paramere broaden subapically with four sensory pores on caudal part ( Fig. 48 View FIGURES 39–51 ). Aedeagal shaft slim and straight with two pairs of slim and unbranched apical appendages; dorsal appendages with a short protrusion near apical 1/3 and adjacent to ventral appendages basally ( Figs 46–51 View FIGURES 39–51 ).

Specimens examined. Holotype: ♂, China, Yunnan Prov., Sanchahe , 7 June 1991, coll. Rungang Tian . Paratypes: 35 ♂, same data as holotype ; 1 ♂, China, Yunnan Prov., Mengyang, 7 June 1991, coll. Rungang Tian and Yinglun Wang.

Measurement. Length of male 3.38–3.63 mm (including wing).

Etymology. The specific epithet is derived from the Latin word “ flatilis ” referring to paramere broaden subapically on the caudal part.

Remarks. This new species resembles E. (S.) hema in male genitalia, but differs in having the aedeagal shaft with dorsal appendages twice as long as the ventral appendages ( Figs 46–51 View FIGURES 39–51 ), while in the E (S.) hema , the dorsal and ventral appendages of the aedeagal shaft are nearly equal in length.
