DESCRIPTION.
MALE. Measurements: length: 9.0 mm, width: 4.0 mm.
Body: relatively elongate, slightly bent, sides parallel, broader in middle of elytra; abdomen concave; process at base of prosternum pointed; reddish-brown, elytra with lines of dark brown irregular spots, pygidium and tarsi dark brown; apex of upper lip, apex of mandible and outer part of apex of protibiae blackish; slightly shiny.
Head: broad; clypeus rounded, entirely reflexed, imbricate-punctate; vertex with close, shallow horseshoe-shaped punctures; antennae with 10 antennomeres, with club longer than funicle.
Thorax: pronotum rectangular, wider than long; sides slightly angular in middle part; all margins with complete marginal line; anterior angles slightly projecting and reaching posterior margin of eyes; shallow horseshoe-shaped punctures; small foveola on lateral margins; scutellar shield subobtuse with shallow horseshoe-shaped punctures.
Elytra: longer than wide; epipleura complete; primary costae slightly elevated; striae with shallow horseshoe-shaped punctures; humeral calli slightly marked, apical calli well marked.
Pygidium: triangular with two lateral impressions, apex rounded, marginated along anal plate, slightly projecting postero-ventrally and not surpassing apex of elytra, coriaceous-punctate.
Venter: lateral part of metaventrite with shallow horseshoe-shaped punctures, median part smooth; abdominal ventrites from 2 nd to anal plate shallowly imbricate-punctate.
Legs: protibiae tridentate and relatively slender, inner claw elongate and cleft, slightly shorter than last tarsomere, mesotarsal outer claw cleft; outer claw of metatarsus 2 times longer than inner one and uncleft.
Setation: upper side covered with short, white, squamous decumbent setae, antennae, canthus, inner margin of eyes, anterior angles of pronotum and along margin of anterior part of elytra with long and short isolated yellowish setae; lines of tufts of short, isolated semi-erected white scales alternately with little glabrous and shiny dark brown areas on elytra; tuft of close and erected white scales on top of apical calli; underside with short white, squamous decumbent setae together with sparse, long, erected brownish-yellow setae inserted in setigerous punctures on abdominal ventrites; long, erected, whitish squamous setae on base of labrum and on prosternal process; long and close whitish setae along anterior margin of pronotum; two transversal tufts of well-separated long and erected white squamous setae on disc of pygidium.
Aedeagus: in lateral view, parameres perpendicular to median part, dorsally strongly sinuate next to base, apex ventrally curved; in dorsal view, subtriangular, narrower and angular in middle part, apex slightly sinuate.
FEMALE: unknown.

A. matotokensis View in CoL sp. nov. ( Fig. 15 View Fig )
Aedeagus: in lateral view, parameres perpendicular to median part, dorsally strongly sinuate after base, apex ventrally curved; in dorsal view, subtriangular, narrower and angular in middle part, apex slightly sinuate.
A. vanderberghei Limbourg, 2017 ( Figs 15–16 View Fig View Fig ).
Aedeagus: in lateral view, parameres rather elongate, slightly bisinuate dorsally, apex straight; in dorsal view, triangular with apex strongly sinuate.
