Paracladiscus Miyatake, 1965

Paracladiscus Miyatake, 1965: 20 (original description).

Type species. Paracladiscus atricolor Miyatake, 1965 , by original designation.

Diagnosis. Paracladiscus is similar to Diplopherusa , but distinguished by the following characters: head and pronotum covered with deep and large punctures; terminal palpomeres of labial palpi triangular, as long as width of apical margin of terminal palpomeres ( Fig. 22 ); gula with two separate postgular processes, which are not swollen at extremities; anterior plate of metendosternite ( Fig. 23 ) tapered anteriorly; hind tibiae in male ( Fig. 24 ) weakly swollen in middle and apically curved inwardly; phallobasic struts (Figs 52, 54) not developed.

Remark. MIYATAKE (1965) mentioned that the feature of male antennae is significant for the distinction between Paracladiscus and Diplopherusa . However, the herein described species, Paracladiscus choui sp. nov., has ramose antennae like Diplopherusa , therefore this character cannot be considered a distinctive feature for the two genera.
