Diagnosis.
Length
1.2–1.5 mm
, 2.4–2.6 × as long as wide. Frons flattened, smooth, shiny and impunctate on lower central half, sharply granulated above, with scant, short setae; eyes separated above by 3 × their width; antennal club glabrous and shiny on basal three-fourth, with one procurved suture near apical margin. Pronotal asperities on anterior half mainly separated, subcontiguous at summit; vestiture hairlike. Elytral striae not impressed, interstriae with spatulate and partly truncated setae spaced by their length, strial setae minute. Protibiae with three lateral and apical denticles. Ventral setae several times longer than elytral setae.

lectotype (14, 17, 20).
Remarks.
Additional specimens to the
holotype
were collected in the Uluguru mountains in
Tanzania
, and
Congo
west of the Ruwenzori, both between 1700 and
2300 m
altitude. The record from
Congo
is a new country record. The type locality in the Usambara mountains is situated at
1500 m
altitude.
Schedl (1977)
reported this species, subsequent to his original description, as
Dendrochilus setifer
and the type is also located together with
Dendrochilus
(
sensu
Schedl) in the NHMW collection. This species is very similar to
A. jasminae
but is clearly differentiated by the sharp granules on the upper frons. A more complete sampling of males and females from
A. mikaniae
,
A. jasminae
and
A. setifera
is needed to confirm species status for this complex.
