Etymology:
Named after Lake Kenyir, in whose vicinity the
types
were collected.
Diagnosis:
The species can be recognized by the lack of prominent eyes, distinctly crenulate lateral margins of the pronotum, rows of elytral punctures without setation, distinctly convex elytral intervals, distinctly crenulate lateral intervals in the humeral region, and aedeagus with joint subquadrate parameres.
Laena kenyirica
n. sp.
runs in the key of the Malaysian species (
Schawaller 1995
) to the species
Laena gentingica
Schawaller, 1995
and
Laena brinchangensis
Schawaller, 1995
; both with a smaller body size, distinctly prominent eyes, a different shape of the pronotum, a different dorsal punctation and setation, and a different shape of the aedeagus with joint triangular parameres.
Laena kenyirica
n. sp.
differs from the syntopic
Laena schulzi
n. sp.
by the bigger body size, by a different shape of pronotum and elytra, by distinct dorsal setation and by a different shape of the aedeagus.
Description:
Body length 3.8–4.8 mm. Eyes not prominent. Pronotum (
Fig. 5
) with large punctures, distance between 0.5–3 diameters, most punctures bearing long erect seta; surface flat, shining; lateral margin distinctly bordered, crenulate; propleura with similar punctation but without setation. Elytra (
Fig. 5
) with complete rows of punctures without striae, punctures equal in size to pronotal punctures, without setae; intervals with row of fine punctures each bearing long, erect seta; all intervals convex, shining, external intervals near humeral region serrate by punctures; interval
7 in
the humeral region with indistinct setiferous pore, interval 9 with 4 indistinct setiferous pores. Femora in both sexes without distinct tooth or other modification. Tibiae in males without distinct sexual character. Aedeagus see
Fig. 19
.
Remarks:
Laena kenyirica
n. sp.
(and the syntopic
Laena schulzi
n. sp.
, see below) populates lowland forest in the northeastern part of the Malayan Peninsula, thus living disjunctly from the
type
localities of all the other known Malaysian species in the central mountain ranges above
1000 m
. This different distributional and biological patterns might be considered as further arguments for the specific validity.
