Dipropus warneri new species

( Fig. 9–10 , 17 )

Description. As for D. pericu , except length 8.1–11.4 mm, width 2.3–3.4 mm. Integument testaceocastaneous.

Head with ocular index 67. Antenna moderately long, reaching to metafemoral angle of elytra, antennomere 8 reaching apex of hind angle, antennomeres 2–3, 7, 11 length ratio 1.0:3.5, 3.6, 5.8.

Pronotum slightly wider (1.1x) than long; trapezoidal; lateral margin strongly carinate at hind angle, sinuate at midlength; integumental punctures coarse, umbilicate, approximate, becoming slightly sparser, separate by 0.2x own diameter on posterior declivity. Hind angles strongly divergent at base, slightly incurved apically; with strong dorsal carina near lateral margin.

Elytra with intervals shallowly convex throughout, becoming obscurely corrugated apically; apices conjointly rounded to subtruncate.

Metaleg with tibia 1.2x length of femur, tarsus 0.8x length of tibia; tarsomere length ratio 1.00:0.47:0.21:0.21:0.74.

Aedeagus as in Fig. 12 ; basal piece 0.63 of total length, paramere 0.42 of total length, paramere apex 0.29 of paramere length.

Female: As for male, except body form subparallel; pronotum length 0.82–0.85x width; antenna short, antennomere 10 reaching apex of hind angle, antennomere 2–4, 11 length ratio 1.0:2.2:2.0, 3.0; metatarsomere length ratio 1.0:0.44:0.22:0.11:0.77; ventrite 5 with punctures small, simple, evenly distributed.
