Zhou, Xian, Dietrich, Christopher H., Zhang, Yalin & Huang, Min, 2020, Five new species of the leafhopper genus Limassolla Dlabola (Hemiptera Cicadellidae: Typhlocybinae), Zootaxa 4878 (3), pp. 559-571 : 564-567

Limassolla uncata Huang & Zhang sp. nov.

( Figs 3, 8, 13, 18 , 37–45 )

Body small ( Fig. 3 ). Eyes brown. Frontoclypeal area with 2 patches white ( Fig. 13 ). Crown with 2 oval white patches near anterior margin; longitudinal patch along coronal suture white ( Fig. 8 ). Pronotum with 5 patches white; 2 long patches laterally white. Scutellum with basal triangles and apex orange ( Figs 3, 8 ). Forewing nearly transparent with 2 small brown spots on outer margin of middle part and 3 small brown spots on inner margins at apex; 3 patches on clavus orange ( Figs 3, 18 ).

Abdominal apodemes slightly surpassing posterior margin of 4th abdominal sternite ( Fig. 37 ).

Male genitalia: Pygofer side with ventral process elongate, sinuate and surpassing dorsal margin of lobe; few rigid setae on disc ( Fig. 38 ). Subgenital plate slim with long macroseta at base, a row of fine setae along outer margin subbasally and numerous rigid microsetae scattered on apical half ( Figs 39, 40 ). Paramere with subapical protrusion indistinct and terminal part short ( Figs 41, 43 ). Connective with median anterior lobe prominent, slender ( Figs 42, 43 ). Aedeagus with preatrium well developed; shaft simple, tubular, gradually tapered toward apex, apex with small partial hood extended from left side over gonopore. Gonopore apical ( Figs 44, 45 ).

Specimens examined. Holotype: ♂, China, Guizhou Prov., Mt. Fanjing , 600m, at light, 27.vii. 2001, coll. Qiang Sun. Paratypes: 1♂ & 1♀, same data as holotype .

Measurement. Male, 2.9–3.0mm (including wing).

Etymology. The specific name is derived from the Latin word “uncatus”, referring to aedeagal shaft with a small hood hooked over the gonopore.

Notes. This new species belongs to the Limassolla multipunctata group and resembles L. kunyica sp. nov. in the structure of the aedeagus and pygofer, but differs in lacking lateral ridges on the aedeagal shaft and having a partial hood over the gonopore. Both of two species also resemble L. ishiharai and L. rubrolimbata , but two new species differ in the apex of the shaft irregularly rounded, subgenital plate with long macroseta at base.
