Zheng, Yan, Chen, Jun & Wang, Xiaoli, 2016, A new genus and species of Tettigarctidae from the Mesozoic of northeastern China (Insecta, Hemiptera, Cicadoidea), ZooKeys 632, pp. 47-55 : 49

Taxon classification Animalia Hemiptera Tettigarctidae

Maculaprosbole gen. n.

Type species.

Maculaprosbole zhengi new species, designated herein (Fig. 1). No other species are currently included in the genus.

Etymology.

The generic name is a composition of the Latin “macula”, meaning spots and stripes, and the suffix of the genus of Cicadoprosbole Becker-Migdisova, 1947.

Diagnosis.

Forewing large-sized, relatively wide and with oblique apical margin. Wing membrane with distinct color patterns. Clavus and costal area long. Nodal line at the middle of wing. Nodus distinct. RA with three branches; crossvein ir halfway from nodal line to wing tip; vein RP single and extended upward along the nodal line; vein M four-branched; M1+2 branched beyond M3+4; M1+2 fork into M1 and M2 with a right angle, and M1 fused with RP for a distance, then nearly parallel to M2; crossvein r-m absent; crossvein m nearly straight, almost perpendicular to M2; vein CuA strongly downward along nodal line, branching into CuA1 and CuA2 just after nodal line; vein CuP almost straight, ending at about 2/5 of wing.

Remarks.

The new genus undoubtedly belongs to the family Tettigarctidae based on the following diagnostic characteristics of the forewing: nodal line clearly visible; vein RA three-branched; intercostal area widest beyond nodal line; vein RP single and strongly bowed; vein M four-branched. The stem of M is shorter than ScP+R. Maculaprosbole gen. n. is assigned to the subfamily Cicadoprosbolinae based on the forewing features: costal area broad, basal cell narrow; clavus arched; branch CuA2 long, sinuous and near S-shaped. This genus is most similar in coloration pattern of forewing (such as dark or light speckles, longitudinal stripes) with Sanmai Chen, Zhang & Wang B 2016, but differs from Sanmai in the transverse coloration mainly focusing on the postnodal area. Maculaprosbole shares some features in forewing venation with that of Hirtaprosbole Liu, Li & Yao, 2015: nodal line at middle of forewing, RA three-branched; stem ScP+R longer than stem M; CuP straight; cell a6 nearly quadrate; cell a8 subequal to cell a10 in length. However, it differs from Hirtaprosbole in the following characters: stem ScP+RA separated at the nodal line, ScP ending beyond the middle of anterior margin M1 fused with RP for a distance and crossvein r-m absent (vs. r-m is located between M1 and RP); apical CuA section strongly curved, running along nodal line for a distance (vs. CuA slightly sigmoidal, not along nodal line).
