Etymology: The specific epithet is the present participle of the Latin verb eminere (to stand out) and alludes to the prominent crista apicalis of the aedeagus.

Description: Body length 2.3–2.6 mm; length of forebody 1.1–1.2 mm. Coloration: head brown to darkbrown; pronotum pale-reddish to dark-reddish; elytra yellowish with a relatively small medio-lateral spot; abdomen distinctly bicoloured, with segments III–IV and the anterior margin of segment V reddish and the remainder blackish-brown to black; legs yellowish; antennae brown with the basal 3–4 antennomeres reddish.

Head approximately 1.15 times as broad as long, without appreciable sexual dimorphism; punctation moderately dense and fine. Eyes much longer than postocular region in dorsal view. Antennae approximately 0.8 mm long; antennomere IV approximately as long as broad or weakly transverse; antennomeres V–X of gradually increasing width and increasingly transverse, X approximately 1.5 times as broad as long.

Pronotum approximately 1.15 times as broad as long and approximately as broad as head, with or without very indistinct sexual dimorphism.

Elytra approximately as long as, or slightly longer than, pronotum; punctation dense and very fine. Hind wings fully developed.

Abdomen slightly narrower than elytra; punctation distinct, denser in anterior than in posterior portions of tergites; posterior margin of tergite VIII ( Figs 84, 89 ) strongly convex in the middle, postero-laterally with a cluster of long thin setae; marginal setae thin and moderately long.

♂: pronotum on average with more distinct punctation than in female, sometimes weakly impressed in posteromedian portion; posterior margin of sternite VIII ( Fig. 85 ) strongly convex, marginal setae moderately long, thin, and evenly spaced; median lobe of aedeagus ( Figs 86–88 ) approximately 0.25 mm long; ventral process sinuate in lateral view, broad and apically of broadly triangular shape in ventral view; crista apicalis prominent in lateral view.

♀: posterior margin of sternite VIII ( Fig. 90 ) broadly convex.

Comparative notes: Anaulacaspis eminens is distinguished from other small species of similar coloration ( A. persica and allied species) only by the shape of the abdominal tergite VIII and by the morphology of the median lobe of the aedeagus, from the sympatric A. persica also by the paler coloration of the abdominal segments III–IV.

Distribution and natural history: The type specimens were collected in several localities in Hormozgan and Kerman provinces, South Iran, and in Afghanistan ( Map 3 ). The altitudes range from 850 to 3360 m. The specimens were collected partly on the banks of rivers, partly from under stones on stony slopes.
