Figures 3C , 4G-I , 5C , 8A, B

Macrolycus dotatus Kleine, 1925: 328; 1933: 5; Nakane, 1967: 73; Li et al., 2012: 49.

Material examined.

China • 1♂ (IZAS); Yunnan, Simao ; 13.IV.1955; Y. Z. Zi leg. ; 1♀ (IZAS); same locality; 13.IV.1955; Y. Z. Zi leg.

Descriptive notes.

Male (Fig. 3C ). Antennae (Fig. 5C ) flabellate, overlapping two-thirds the length of the elytra when inclined. Antennomere II transverse; III-XI lamellate, antennomere III with lamella nearly as long as joint, and lamella of IX longest, 5.0 times longer than joint itself. - Aedeagus: median lobe moderately curved near middle in lateral view, at an angle of ca. 150° between basal and apical parts of dorsal side, distinctly arcuate at base part, subapical part moderately inflated dorsally (Figs 4I , 8A ); nearly straight at basal part in ventral view, subapical part strongly inflated laterally (Figs 4H , 8B ), with a fusiform ventral-cavity (Fig. 4H ); apical part gradually narrowed distad, with a deep V-shaped notch at apex (Fig. 4G ).

Distribution.

China (Hainan, Guangxi, Guangdong, Yunnan), Vietnam, Laos.

Remarks.

In the latest work ( Li et al. 2012), this species was not illustrated. Here, we provide illustrations of the male habitus, antenna and aedeagus to make it better known.

Figure 8. Differences in the shape of the median lobe of the Macrolycus dotatus species group in relative warps computed from the dataset in lateral (A) and ventral (B) views, plotted against one another to indicate positions of the relationships among the species. The shape changes of different species implied by variation along the first two relative warp axes. Shape changes are shown as deformation of the GLS reference, using tps configurations. The reference configurations (situated at the origin) shown in lateral (a) and dorsal (b) views, those at the left, right, top and bottom are indicated by arrows, and each species is represented by a different color.
