Description.
Colour
. Head fuscous except brown anteclypeus, antenna reddish brown, anterior half of pedicel stramineous; pronotum stramineous, anterior pronotal disk mostly brown; scutellum stramineous; clavus except a small spot, anterior half of corium and some obscure spots on apical half of corium whitish, posterior half mostly brown, endocorium posteriorly between inner rows of punctures black (sometimes white and brown areas also obscurely bordered with black); membrane translucent, margin with most parts of veins brown to black; sternum fuscous; legs except preapical brown ring of femora stramineous; abdomen brown, posterior half of connexival segments dorsally and ventrally pale.
Structure
. Similar to
L. puskasi
sp. nov.
(
Fig. 3
) but labium reaching end of mid coxae, segment I attaining base of head. Anterior lobe of pronotum provided with a pair of strong elevations close to transverse impression. Pronotum with slightly elevated impunctate midline between collar and middle part of posterior lobe. Lateral margin of pronotum narrower than diameter of scape. Posterior half of pronotum evenly punctate, punctures separated from each other.
Scutellum with a nearly T-shaped elevated carina with impunctate area on transverse part, midline only slightly elevated, impunctate. Mesosternum with very fine punctures, medially provided with stronger punctures, submedially transversely wrinkled. Metacoxae almost as far apart as mesocoxae.
Measurements

Holotype
(
paratypes
, n = 2), length of labium documented only in
holotype
. Total body length 3.28 (3.14–3.32); head: length 0.55 (0.52–0.56), width 0.80 (0.75–0.80), interocular space 0.50 (0.45–0.51); pronotum: length 0.98 (0.94–0.98), width at base 1.55 (1.46–1.58); scutellum: length 0.68 (0.65–0.70), width 0.76 (0.72–0.78); claval commissure length 0.28 (0.25–0.28); length of antennal segments: scape 0.25 (0.25–0.27), pedicel 0.47 (0.45–0.48), basiflagellum 0.40 (0.38–0.41), distiflagellum 0.50 (0.48–0.52); length of labial segments: I 0.38, II 0.42, III 0.22, IV 0.22.
Differential diagnosis.
Latidrymus elevatus
sp. nov.
differs from the remaining species of
Latidrymus
as well as all other known
Drymini
by having a pair of strong elevations on anterior pronotal lobe (
Fig. 7
). The coloration, especially the continuously dark posterior margin of the membrane, is also diagnostic.
Etymology.
The name of the new species is the Latin adjective
elevatus
(-
a, -um
) meaning elevated or emergent, referring to the pair of conspicuous pronotal elevations.
Collection circumstances.
The specimens from
Luang Prabang
were collected in the remnants of a primary forest, in small wet ravins along brooks (V. Kubáň, pers. comm.). The habitat at
Louang Namtha
is illustrated on
Fig. 13
.
