Dendrochilus Schedl, 1963

Dendrochilus Schedl 1957: 79 unavailable (synonym by Alonso-Zarazaga & Lyal 2009)

Type species: Dendrochilus strombosiopsis Schedl, 1957 (original designation)

Diagnosis, female. Small, elongated species, 2.5−3.0 × as long as wide. Funiculus 5-segmented, scapus at least as long as the funiculus, dilated apically, with a fine tuft of setae along its dorsal side; antennal club elongated, corneous on both sides, shiny and suture-free. Last ventrite elongated, bottleneck-shaped, cylindrical. Proventriculus with crop spines attached on a tubercle, apical plate with median suture wide open, apical spines reduced, closing teeth compact and serrated, masticatory teeth entirely dentated. Male. Similar to female except slightly smaller, scapus narrow, with few setae. Pronotum with two closely set tubercles along the anterior margin. Posterolateral areas of the elytra with sharp interstrial granules. Last ventrite lightly truncated, not cylindrical. Aedeagus with apophyses two times longer than penis, tegmen possibly absent or reduced and located along the apophyses, flagellum long and coiled in its unreleased stage, spiculum gastrale almost as long as aedeagus.

Remarks. Distinguished from other similar genera as described in the key to Afrotropical genera ( Jordal 2021), primarily on the glossy antennal club and the elongated apical ventrite in females. This genus was originally placed with some hesitation in Ipini by Schedl (1957), indicating also a possible relationship to Ernoporini. The type species for the genus was first designated by Schedl in 1963.

In the revision of Afrotropical Micracidini , it was clear that most species of Dendrochilus belong to Afromicracis Schedl, 1959 , but also one was transferred to Xylocleptes Ferrari, 1867 and one to Acanthotomicus Blandford, 1894 ( Table 1 ). It is clear from phylogenetic and morphological analyses that members of this genus form the sister group to Afromicracis (see Jordal 2021).
