Species group formosanus ( Shiraki, 1911)

Figs 1–10

Type species: Ectatoderus formosanus Shiraki, 1911: 192 ( China: Taiwan).

Diagnosis. Compared with other species groups of Ornebius , this species group is distinguished by the male phallic complex, clockwork-like and the medial valve curved to a spiral in basal part with its base forming an axis in the centre of the spiral ( Fig. 1 ).

Besides the type species, the species group includes O. albalatus , O. polycomus , O. apterus , O. panda , O. yunnanensis , Ornebius lunam sp. n. and Ornebius aurumalas sp. n.

Figures

FIGURE 1. Genitalia of three individuals of O. aurumalas He, Zhang & Ma, sp. n. in lateral view. According to the figures, it is difficult to judge species from the lateral view of genitalia, because there are intra-specific differences between individuals of O. aurumalas.
