( Figs 13, 16, 19 )

Dendrochilus mikaniae Schedl, 1957 (original spelling)

Type material. Holotype, female: Congo, Kivu, Mt. Kahuzi [GIS: -2.30, 28.71], 2240 m ( RMCA) . Paratypes (6): same data as HT ( NHMW) .

Diagnosis. Length 1.5 mm, 2.4 × as long as wide. Female frons with fine recumbent setae directed inwards, antennal scapus with small tuft of dorsal setae, club glabrous on basal two-thirds, with distinct procurved suture an apical third; eyes separated above by 2.5 × their width. Pronotum with asperities separated except contiguous on summit; vestiture on pronotum hair- and bristle-like from anterior to posterior margins. Elytral interstria with densely set, bristle-like setae, slightly confused near elytral apex; strial setae minute, mainly on declivity; protibia with one lateral and two apical denticles.

Remarks. This species was recently included as a synonym of A. jasminiae but can be distinguished by the more densely set and lightly confused interstrial setae on the declivity, and the finer setae on posterior half of the pronotum. Genetic data are needed to confirm morphological divergence between the two putatively synonymous species ( Jordal 2021b).
