Diagnosis

Among the yellowish species, A. wanati sp. nov. can be easily identified by the bicolored antennae, with antennomeres 1–4 yellow and 5–11 brown and by the blackish maxillary and labial palpi, distinctly darker than other mouth parts.

Etymology

Male patronym. Named after Dr. Marek Wanat (University of Wroclaw, Poland), one of its collectors.

Description of the holotype (³)

Body moderately elongate and convex ( Fig. 3A View Fig ); LB = 2.66 mm; maximum pronotal width at base (WP = 0.98 mm); maximum elytral width at basal third (WE = 1.33 mm). Dorsum yellowish, non-metallic, with suture and lateral margin of elytra darkened. Frons and vertex microreticulate, with small punctures distinctly impressed; head grooves distinctly impressed, not continued to postantennal region; genae and frontal carina short; maxillary and labial palpi blackish, distinctly darker than other mouth parts; third and fourth maxillary palpomeres flat; antennae clearly longer than half of body length ( LAN = 1.93 mm; LAN/LB = 0.72); antennomeres 1–4 yellow, 5–11 brown; LA: 100:59:59:6 5:100:88:100:91:88:85:115. Pronotum trapezoidal, clearly transverse (LP = 0.53 mm; WP/LP = 1.86), laterally straight ( Fig. 5E View Fig ); anterior angles weakly prominent; antebasal transverse sulcus moderately impressed, slightly sinuate, with distinct punctures on basal side; lateral fovea small; pronotal surface finely microreticulate, with small, shallow punctuation. Elytra moderately elongate (LE = 2.03 mm; WE/LE = 0.65), laterally slightly arcuate; punctuation quite small but clearly larger and more strongly impressed than on pronotum; interstriae very finely microreticulate and sparsely micropunctuate. Legs yellow, with third to fifth tarsomeres darkened; first pro- and mesotarsomeres slightly dilated; adhesive setae present on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter light brown; last abdominal ventrite laterally incised, without special preapical impressions. Median lobe of aedeagus (LAED = 1.08 mm; LE/LAED = 1.88) ( Fig. 10B View Fig ) in ventral view laterally straight, apically widely and regularly rounded; ventral surface with deep median groove, variable in length; in lateral view, median lobe distinctly curved, sinuate at apical third; dorsal ligula short, from apical third to sub-apical part of median lobe of aedeagus, wide, slightly tapered toward apex.
