Macrolycus atronotatus Pic, 1939

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

Macrolycus atronotatus Pic, 1939: 165; Kleine, 1942: 21; Kazantsev, 1993: 50; 2001: 100; Li et al., 2012: 48.

Material examined.

China • 1♂ (IZAS); Sichuan, Emei Mt. ; 2100-3100 m; 25.VI.1955; X. C. Yang leg.

Descriptive notes.

Male (Fig. 3A ). Antennae (Fig. 5A ) flabellate, overlapping two-thirds the length of the elytra when inclined. Antennomere II transverse; III-XI lamellate, lamella of antennomere III 1.2 times as long as joint itself, and lamella of VIII longest, 3.9 times longer than joint itself. - Aedeagus: median lobe nearly in a horizontal line between basal and apical parts on dorsal side in lateral view (Figs 4C , 8A ); almost parallel-sided at basal part in dorsal (Fig. 4A ) and ventral (Figs 4B , 8B ) views, subapical part inflated laterally not dorsally (Fig. 4C ), ventral cavity narrowly fusiform, apical part gradually narrowed distad, with a deep U-shaped notch at apex (Fig. 4C ).

Distribution.

China (Sichuan, Shaanxi).

Remarks.

The type locality is “Chansi” ( Pic 1939), which is inaccurate. Additionally, there is no additional record from Shaanxi in later studies ( Kleine 1942; Kazantsev 1993, 2001; Li et al. 2012). Thus, only the records from Sichuan are present in the distribution map herein.

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.
