Diagnosis
The species is immediately recognized by the following combination of characters:
(1) cephalic process yellow and inflated apically (Fig. 4 D–E).
(2) abdomen red ventrally (Fig. 4B).
(3) tegmina mainly white on disc and with 3 black spots in costal area before nodal line (Fig. 4A).
Etymology
The species was dedicated to its collector, Kenji Watanabe.

Measurements and ratios
TL: ♂ (n=1): 3.9 cm; LPr: 1.0 cm; TL: ♀ (n=2): 4.3 cm (4.0–4.6); LPr: 1.1 cm (1.0–1.2); LTg/BTg = 2.31; BF/BPrH = 2.53; LPr/LF = 2.82; LPr/BPrH = 2.55.
Male genitalia
Pygofer higher than long, with posterior margin sinuate in lateral view (Fig. 8A). Anal tube slightly elongate, 1.1 times as long as broad in dorsal view, broader at 4/5 of total length (Fig. 8C); lateral margins slightly sinuate and apical margin strongly concave in dorsal view (Fig. 8C). Gonostyli (Fig. 8A) elongate, 1.77 times as long as high in lateral view; dorsal margin regularly and broadly rounded and posterior margin slightly projecting posteriorly in middle in lateral view (Fig. 8A).
Biology
The species was recorded on Triadica sebifera (L.) Small (Euphorbiaceae) by Kato (1928), and on the same tree and Sapium discolor Muell. -Arg. (Euphorbiaceae) by Yen & Yang (2015). Those data were confirmed by multiple observations in the field; freshly laid eggs were observed at the end of July, nymphs in February and June (pers. comm. S. Chen, Dec. 2015)
Distribution
Taiwan.
Remarks
This species was mentioned from China by Chou et al. (1985) and Nagai & Porion (1996). However, no specimen of P. watanabei could be found either in the collections of NWAFU, where Chou and co-authors worked (pers. comm. D. Qin, Jun. 2016), in the collections of IZCAS (pers. comm. Z.S. Song, Jun. 2016), or in the collections of MHNL, and there are also no photographic records available supporting the presence of the species on the continent. Hence, the species is removed from the list of Chinese Fulgoridae and is regarded as endemic in Taiwan.
Like in P. clavatus, this species shows specimens with posterior wings entirely white and others with the apical third black.
