Théry) collection of A. kamieserrima sp. nov. was not collected in Northern Cape Province, close the Kamieskroon, but in ‘Natal’ (nowadays Kwazulu-Natal Province). The specimen is somewhat vaguely labelled and, we are not able to confirm or disprove locality. More probably, we think that this old specimen is mislabelled. Nevertheless, the specimen shares all features of A. kamieserrima, including the terminalia, hence it is included to the type series]. All paratypes bear printed red label: ‘ PARATYPUS / Anthaxia (s.str.) / kamieserrima sp. nov. / M. Obořil & P. Baňař det. 2015’.

Diagnosis. Medium sized species (6.8 to 8.1 mm total body length), flat, parallel-sided, blackish, some parts (clypeus, antennae, abdominal ventrites) bronze (males) to greenish tinge (females), always conspicuously shiny.

Description. Measurements (in mm); male holotype first, (female allotype in brackets): Total body length— 6.85 (7.56); maximum width across eyes—1.93 (2.07); dorsal minimum interocular distance—0.60 (0.67); pronotum length—1.64 (1.82); pronotum maximum width—2.60 (2.84); elytron length—4.42 (5.22); elytron maximum width—1.38 (1.51).

Vestiture. Body sparsely covered with short whitish setae, which are denser and longer on dorsum of head, lateral parts of thorax and lateral parts of abdominal ventrites. Pronotum and elytra asetose.

Structure. Head slightly narrower than anterior margin of pronotum (Fig. 18), eyes reniform, not exceeding outline of head. Ocular index 0.9 in males, 0.95 in females. Frons flat. Clypeus broadly heart-shaped. Sculpture of head consists of fine, irregularly ovoid cells, each with a short white seta. Antennae (Fig. 14) slightly shorter than head and pronotum together, scape three times longer than wide, pedicel of the same length as width. Third antennomere narrowest, three times longer than wide, slightly widening apically. Fourth antennomere about 1.5 times longer than wide, strongly widening apically, antennomeres 5 to 10 subtrapezoidal, the same length as width, antennomere 11 subrhomboidal, about 1.5 times longer than wide. Pronotum flat, widest in the anterior third (Figs. 7, 16, 18), ratio of its width to length 1.58 in males, 1.56 in females. Anterior margin of pronotum inconspicuously sinuate. Latero-posterior depressions wide, deep (Fig. 18). Third, unpaired impression situated in the mid-line of pronotum, beginning as shallow drop-like impression in the anterior third of pronotal length, continuing posteriorly, forming shallow groove terminating close to posterior margin. Surface of pronotum bare, without vestiture, with shallow sculpture (Fig. 18), cells more elongate in the latero-posterior impressions. Posterior angles of pronotum rectangular. Thorax ventrally roughly convex, all surfaces coarsely sculptured, with whitish setae. Prosternal process narrowly triangular, pointed apically. Scutellum pentagonal, finely reticulate. Elytra robust and wide (Figs. 7, 20), widest proximally, humeral callosities slightly developed, not projecting beyond the outline of elytron. Laterall margin s-shaped, in distal third finely denticulate. Ratio of length to width of elytron 3.20 in males, 3.45 in females. Elytra proximally with raised area between humeral callosities and apex of scutellum (Fig. 20) passing mesally to shallow impression in proximal third of elytra length. Humeral callosity and its surroundings conspicuously rugate, rest of elytra finely sculptured. Most lateral parts of abdominal ventrites conspicuously visible from above. Legs. Hind tibia straight, with three or four teeth apically on its inner margin (Fig. 26) in males, without teeth in females. Abdomen ventrally strongly convex and wide, shiny bronze in males (Fig. 8), with greenish tinge in females. Anal ventrite (Fig. 28, 30) very short in both sexes, with concave basal margin, roughly denticulate apically. Male terminalia: Aedeagus (Fig. 23) short and wide, ratio of its length to maximum width 4.51. Paramere widest in the middle of its length, narrowing apically. Median lobe robust, widest in proximal third (Fig. 24).

Etymology. Species name is composition of the type locality name Kamieskroon (kamies -) and part of the species name of the closely related species Anthaxia aterrima (- errima).

Distribution. Republic of South Africa, Northern Cape Province (see Discussion).

Differential diagnosis. A. kamieserrima sp. nov. differs from the similar and probably closely related species A. aterrima by more robust and wider body shape (Figs. 7, 8, 20) (slender in A. aterrima — Figs. 5, 6, 19); laterally irregularly rounded pronotum, with two conspicuous latero-posterior impressions (Figs. 7, 16, 18) (pronotum regularly rounded with inconspicuous impressions in A. aterrima — Figs. 5, 15, 17); bronze antenna, with very long antennomere 3, much longer than antennomere 4 (Fig. 14) (antenna black, antennomeres 3 and 4 subequal in length in A. aterrima — Fig. 13); male hind tibia with three or four teeth apically on its inner margin—Fig. 26) (male hind tibia with ten to twelve teeth apically on its inner margin A. aterrima — Fig. 25); anal ventrite short with convex basal margin in both sexes (Figs. 28, 30) (anal ventrite longer with straight basal margin in A. aterrima — Figs. 27, 29) and short and robust aedeagus with different shape of parameres and median lobe to that of A. aterrima (Figs. 21–24).
