Diagnosis.
The new species resembles
M. adisi
in colour and size. Besides the distinctly different shape of the apical parts of the central lobe of aedeagus, the inner endophallus is differently structured in the two species. In
M. huggerti
the elytra are less coarsely and densely punctate than in
M. adisi
. The distance between punctures of
M. huggerti
is more or less half as wide as the diameter of the punctures (
Fig. 5
D), whereas it is smaller in
M. adisi
, in particular adjacent to the suture (
Fig. 5
A).
Description
.
Body length
2.1 mm
.
Body colour
dark brown, legs and antennae yellow.
Head
0.25 mm
long,
0.37 mm
wide; eyes prominent, more than twice as long as temples, setiferous punctation dense and distinct, setae pointing posteriorly, distance between punctures on average half as wide as diameter of punctures, a wide midline without punctures; distinct reticulate microsculpture, surface with subdued gloss.
Antennae
with 2nd antennomere globular, 3rd antennomere conical, but not longer than 2nd, 4th antennomere more or less quadrate, the following antennomeres wider than long and increasing in width, 10th antennomere nearly 3 times as wide as long (
Fig. 4
B).
Pronotum
:
0.37 mm
long,
0.43 mm
wide; sides in front of posterior emargination more or less parallel, punctures larger and deeper than on head, distance between punctures less than half as wide as diameter of punctures, a wide midline without punctures, setae pointing to the middle, reticulate microsculpture denser and deeper than on head, surface with subdued gloss.
Elytra
0.50 mm
long,
0.47 mm
wide; with large and deep punctures, punctation as dense as on pronotum, but less distinct owing to the deep and dense reticulate microsculpture, surface matt, setae pointing to the middle.
Abdomen
with much finer setiferous punctation than on pronotum and elytra, barely visible in the distinct reticulate microsculpture, surface matt.
Mesotibia
of male widest near the middle, weakly narrowed towards apex, at inner side with a comb of short setae, posterior side densely covered with setiferous punctures (
Fig. 4
C).
Aedeagus
with short straight apex and short paramera (
Fig. 4
D).
Etymology.
The specific name is derived from the collector’s name, L. Huggert.
