Laena kurbatovi
n. sp.
(
Fig. 8
)
Holotype
(Ψ): N
Burma
,
Chin
Prov., Saw,
900–1500 m
,
27.–28.II.1996
, leg. S. Kurbatov,
HNHM
.
Etymology:
Dedicated to Sergej A. Kurbatov (Moscow), collector of the
holotype
.
Diagnosis:
Separated from the single known species from
Burma
(
Laena bicolor
Schuster, 1926
) by the smaller body size (5.0 mm in
Laena bicolor
), lack of prominent eyes (prominent in
Laena bicolor
), distinctly bordered lateral margin of the pronotum (unbordered in
Laena bicolor
), the distinct row of punctures on the elytral intervals (smooth in
Laena bicolor
), and several setiferous pores on elytral interval 9 (a single toothlike setiferous pore on interval
9 in
bicolor
). Because of these distinct differences, I decided to describe this species from a quite remote area as new even without having a male available (the aedeagus of
Laena bicolor
thus unknown).
Laena kurbatovi
n. sp.
is quite similar to
Laena vietnamica
Masumoto, 1995
from northern
Vietnam
and
Laena champasaka
n. sp.
from southern
Laos
, but can be separated by differently shaped pronotum and different dorsal punctation and setation (compare
Figs 1, 8
,
15
). See also under
Laena khaolaka
n. sp.
from southern
Thailand
with slightly armed femora (
Fig. 6
).
Description:
Body length 3.7 mm. Eyes not prominent. Pronotum (
Fig. 8
) with large punctures, distance between 1–4 diameters, most punctures bearing long erect seta; surface flat, shining; lateral margin distinctly bordered, somewhat crenulate; propleura with similar punctation, setation to disc. Elytra (
Fig. 8
) with complete rows of punctures without striae, punctures equal in size to pronotal punctures most bearing long, erect seta; intervals with a row of distinct punctures each bearing erect seta of similar length, anterior of interval 9 with several setiferous pores so that the shoulder looks dentate; all intervals distinctly convex, shining. Femora without distinct tooth or other modification. Sexual dimorphism unknown. Aedeagus unknown, only female available.
