Meng, Rui, Wang, Yinglun & Qin, Daozheng, 2016, Four new species of the genus Mongoliana Distant (Hemiptera: Fulgoromorpha: Issidae) from southern China, Zootaxa 4061 (2), pp. 101-118 : 107-109

Mongoliana albimaculata sp. nov.

( Figs 21–23 & 45–50 )

Diagnosis. This species is similar to M. lanceolata ( Figs 71 & 72 ), but differs from the latter in tegmina and male genitalia (features of M. lanceolata in parentheses): tegmina pale flavovirens with five white blotches (tegmina fuscescent with a pale linear macula near middle of inner margin); anal tube in dorsal view with apical margin convex medially (apical margin concave medially); lateral lobes of phallobase with five denticles caudodorsally, aedeagus with pair of processes, crenated caudoventrally (lateral lobes of phallobase without denticles, aedeagus with paired processes smooth caudoventrally).

Description. Male length (N=1) (including tegmina): 4.1 mm, length of tegmina: 3.5 mm; female length (N=1) (including tegmina): 4.6 mm, length of tegmina: 4.1 mm.

Coloration. Body yellow green. Vertex, frons and pronotum fusco-piceous. Vertex with fulvous spots. Frons yellow at apex, with numerous tubercles. Frontoclypeal suture and clypeus black except a transverse yellow fasciae at base of clypeus. Mesonotum and rostrum fuscous. Pronotum with light tubercles. Mesonotum scattered with pale tubercles or granules, white at apex. Tegmina yellow green, with five small white maculae, the largest one at middle of posterior margin. Hind wings light brown, veins fulvous. Fore leg black, pro-femur and tibia dark yellow at base and apex; median leg dark yellow with black longitudinal stripes and maculae; hind leg dark yellow, postfemur black. Abdomen dark brown ( Figs 21–23 ).

Head and thorax. Vertex with anterior margin moderately straight, approximately 2.1 times wider at base than long in midline ( Fig. 21 ). Frons rugous and granulose, median length almost equal to maximum width, about 1.9 times wider at widest part than at upper margin ( Fig. 22 ). Frontoclypeal suture straight ( Fig. 22 ). Pronotum coarse, with six large tubercles laterally and numerous small pustules ( Fig. 21 ). Mesonotum large and rugose, pustules numerous, median carina weak; about 2.1 wider at widest part than long in midline ( Fig. 21 ). Hind wings translucent, about 0.8 times length of tegmina, veins ScP+R (2), MP (4), CuA (2), CuP (1), Pcu (1); ScP+R furcate before wing middle and shortly branched in apical half of the wing, with three transverse veinlets between ScP+R and costal margin, and with secondary veins forming quadrangular cells, median posterior furcates in apical part, cubitus anterior furcates beyond middle, and shortly branched at apical part of wing ( Fig. 45 ). Metatibiotarsal formula 2+6/7/2.

Male terminalia. Anal tube subtriangular, apical margin sinuate in dorsal view, angularly convex medially, laterocaudal angles slightly projected ( Fig. 47 ). Anal column situated in the middle of anal tube ( Fig. 47 ). Pygofer in lateral view with posterior margin roundly convex submedially, slightly concave in basal 2 / 5 ( Fig. 46 ). Aedeagus with a pair of long hooks from middle, reaching to the base of aedeagus; lateral lobes of phallobase distinctly sclerotized and sword-shaped, with five teeth on dorsal margin near apex; ventral lobe narrow in ventral view, apical margin slightly convex ( Figs 49 & 50 ). Genital style with hind margin obviously concave ( Fig. 46 ). Capitulum of style short and acute at apex, with a large lateral tooth ( Fig. 48 ).

Material examined. Holotype: male, China, Guizhou Province, Wuyanqiao, Libo County, Maolan National Nature Reserve, 28 July 2012, coll. Lifang Zheng ( NWAFU). Paratype: 1 female, same data as holotype ( NWAFU).

Etymology. The specific epithet is derived from the Latin words “ albus ” and “ macula ”, referring to the white maculae of the tegmina.

Distribution. China (Guizhou) ( Fig. 81 ).
