Diagnosis.
This species, and both
M. kavanaughi
and
M. sedlaceki
, are characterized by the third antennomeres with the apical half bearing fine short setae in addition to the larger apical ring setae.
Mecyclothorax kubor
and some individuals of
M. kavanaughi
also exhibit five dorsal elytral setae in the third interval, although
M. kavanaughi
beetles possess setose fifth elytral intervals, whereas that interval is glabrous in
M. kubor
.
Mecyclothorax sedlaceki
differs from both through the presence of only two dorsal elytral setae in the third interval.
Mecyclothorax kubor
is also characterized by the presence of a parascutellar seta, whereas this seta is lacking in individuals of
M. sedlaceki
and variably present or absent among individuals of
M. kavanaughi
. Body length is
4.4 mm
(
Baehr 2008
).
Distribution and Habitat.
The unique
holotype
of this species was collected at
3,590 m
elevation on Mt. Kinkain in the Kubor Range,
Western Highlands Province
(
Fig. 32
). The specimen was collected by W. Vink, a botanist at the National Herbarium, University of Leiden, during the herbarium’ s 1963 Kubor Range Expedition (Steenis- Kruseman 1973). At
3,600 m
elevation on Mt. Kinkain, the vegetation on less peaty substrates is natural alpine grassland dominated by tussock grasses of the genera
Deschampsia
Palisot de Beauvois
,
Poa
L., and
Festuca
L., while on more poorly drained, peaty soils, a low heath-like formation occurs that includes, among others, cushionforming species of
Potentilla
L.,
Astelia
Banks and Solander
, and
Gentiana
L. (
Hitchcock 1964
).
