Kubá&amp;ncaron;, pers. comm.). <b>Type material.</b> HOLOTYPE: 1 J, ‘LAOS, Louang Namtha pr., / 21°09’ N 101°19’ E, / Namtha → Muang Sing, / 5-31. V. 1997, 900– 1200 m, / Vít Kubá&amp;ncaron; leg. // Vít Kubá&amp;ncaron; expedition / „Laos 1997” / Moravian Museum Brno / Czech Republic (MMBC). PARATYPE: <b>LAOS: KHAMMOUANE PROVINCE:</b> 1 J, ‘LAOS, 24.-29. IV. 2001 / 18°07’ N 104°29’ E / Khammouan pr. / Ban Khoun Ngeun / ca. 200m V. Kubá&amp;ncaron; lgt.’ [exactly 18°08′45″N 104°27′20″E, 180 m a.s.l., V. Kubá&amp;ncaron;, pers. comm.] (MMBC). <b>Description.</b> <i>Colour.</i> Nearly unicolorous reddish brown, head, anterior disk of pronotum and sternum (except metepisternum) slightly darker than the rest of body, distiflagellum fuscous; basal part of posterior half of pronotum between the punctures whitish; basal part of scutellum brown; clavus and anterior part of corium indistinctly paler than the rest, second 2/5 of costal margin and three tiny, indistinct spots on apical half of corium pale; membrane translucent, small spots (streaks on veins and triangular spots on margin at end of veins) fuscous; legs stramineous; abdomen reddish brown, posterior third of connexival segments dorsally and ventrally pale. <i>Structure</i> as in <i>L. puskasi</i> sp. nov. but anterior half of pronotum widest at transversal furrow (slightly narrower in medial portion of anterior pronotal lobe) (Fig. 5). No elevations on anterior half of pronotum; pronotal midline insignificant; basal quarter of pronotum sparsely punctate with large impunctate areas; lateral margin finely serrate. Mesosternum with very fine punctures only, medially not transversely wrinkled. Labium reaching end of mid coxae, segment I reaching base of head. Abdomen very finely and rather sparsely punctate, not wrinkled, shiny. Paramere slender with short sensory lobe (Fig. 12). <i>Measurements</i> (in mm). Holotype (paratype), length of labium provided only for holotype. Body length 2.95 (2.82); head: length 0.45 (0.42), width 0.72 (0.70), interocular space 0.42 (0.42); pronotum: length 0.85 (0.82), width at base 1.42 (1.39); scutellum: length 0.65 (0.62), width 0.72 (0.70); claval commissure length 0.22 (0.24); length of antennal segments: scape 0.22 (0.22), pedicel 0.38 (0.38), basiflagellum 0.40 (0.38), distiflagellum 0.51 (0.50); length of labial segments: I 0.35, II 0.46, III 0.22, IV 0.26. <b>Differential diagnosis.</b> <i>Latidrymus flavus</i> sp. nov. is the only species in the genus which has a rather unicolorous corium (without dark spot and basal half of it not paler than apical half). This is also the only species of the genus characterised by large impunctate areas on basal part of pronotum and where the pronotum is continuously tapering anteriad. The fine serration of the lateral margin of the anterior lobe of pronotum is the strongest in this species. It is different from <i>L. elevatus</i> sp. nov. and <i>L. zetteli</i> sp. nov. in lacking elevations on anterior half of pronotum and in insignificant pronotal midline. <b>Etymology.</b> The name of the new species is the Latin adjective <i>flavus</i> (<i>-a, -um</i>), meaning yellow, referring to the coloration of its body. <b>Collection circumstances.</b> The specimens from Luang Namtha were collected in remnants of a primary forest, in small wet ravines along brooks (Fig. 13). Specimens from Ban Khoun Ngeun were collected in remnants of a (probably primary) lowland forest, near a large river (V. Kubá&amp;ncaron;, pers. comm.). <b>Distribution.</b> Northern and central Laos (Luang Namtha and Khammouane Provinces, respectively) (Fig. 13).
