Allochotes choui Murakami & Yamasako, 2012: 48 .

Type materials. Holotype: ♂ (EUMJ), “Pingtung TAIWAN / Dahanshan (1,500m)/ Chunri Township/ 30~ 31. III. 2012 / N. OHBAYASHI leg.” [locality name also written by Chinese character]. Paratypes: 1♂ (EUMJ), same data as holotype; 2♂♂ (EUMJ), same locality as holotype, 11–12. IV. 2012, N. Ohbayashi leg.; 3♀♀ (EUMJ), same data, J. Yamasako leg.

Type locality. Mt. Dahan-shan, Chunrih Township, Pingtung County, Taiwan.

Diagnosis. This species is easily separated from the other Taiwanese congeners by the following characteristics: elytra black, dully shining, with large milky white markings; antennomeres 3 to 11, subsutural area of elytra, tibiae and tarsi black; pterothoraces in ventral view yellowish orange. This species is very similar to A. yichei , but also distinguished by the following structures in addition to the above external features: pygidial struts curved outward distally, spicular fork with depigmented spicular lobes; fully inflated phallus nearly orthogonal or acute to the tegmen; phallobasic apodeme short, stout; phallic plates thin.

Additional description. Male (n = 4, Fig. 2 A): Antennomeres 4 to 6 weakly serrate, gradually shortened toward apical segments; 7th to 10th serrate; 7th and 8th as wide as long; 9th and 10th wider than long.

Aedeagus in fully inflated condition ( Fig. 6 G) orthogonally or acutely curved at the base of CM in lateral view; CM swollen cylindrically, slightly dilated basally; phallus cylindrically swollen in basal half, thence tapered apically. Phallic ventral membrane ( Fig. 6 H) with a linear median sclerite.

Female (n = 3): Pygidium ( Fig. 7 E) trapezoidal; pygidial struts stout, short. Eighth sternite ( Fig. 7 F) with apical margin incised at middle.

Distribution. Taiwan (Pingtung).
