Postclypeus moderately swollen, mostly ochraceous, with paired brown oblique fasciae just anterior to frontoclypeal suture and a long “ Y ” - like brown median fascia ventrally, with 10–11 wide transverse grooves on each side. Anteclypeus ochraceous along median carina and brown laterally. Gena ochraceous, with oblique black fascia in anterior part. Lorum black in about posterior half and ochraceous in about anterior half. Rostrum ochraceous with blackish apical part, reaching middle of sternite II.

Variation.

All male or female types without evident variation.

Field observations.

A living male of the new species is shown in Fig. 6 A, B View Figure 6 and its habitat in Huboliao National Nature Reserve is shown in Fig. 6 C, D View Figure 6 . According to the collectors’ recollection, during the collecting trip in late October, this cicada was abundant in the reserve, but the individuals were difficult to capture. They were in the canopy and not attracted to light traps at night, so the collectors had to climb up the trees to capture them.

Distribution.

China (Fujian) (Fig. 7 View Figure 7 ).

Differential diagnosis.

The new species well resembles its only congener C. duffelsi from Vietnam in general appearance, but it is not difficult to distinguish them using the following key.

Additionally, although many species in Cicadinae exhibit morphological variations in markings and operculum length, they still have certain reference characteristics:

In C. duffelsi , pronotal collar with three paired large spots ( Pham and Constant 2017: figs 2 A; 3 A); mesonotum with median fascia moderately tapering anteriorly and weakly so posteriorly, lateral fasciae relatively slender, accessory spots absent ( Pham and Constant 2017: figs 2 A; 3 A); opercula reaching posterior margin of sternite VI ( Pham and Constant 2017: figs 2 B; 3 B). In C. huboliao sp. nov., pronotal collar with two paired large spots (Fig. 1 A View Figure 1 ); mesonotum with median fascia strongly tapering anteriorly and moderately so posteriorly, lateral fasciae relatively wide, small accessory spots lateral to accessory fasciae (Fig. 1 A View Figure 1 ); opercula extending beyond posterior margin of sternite VI (Fig. 1 B View Figure 1 ).
