description: Sinophlaeba laoyinshan sp. nov.
(Figs. 1–10)
Type material. Holotype: male, CHINA: Yunnan: Gejiu, Mt. Laoyinshan, 1560m, 6 May 2005, collected by Chang-cui Guo. Type specimen is deposited in the Faculty of Conservation Biology, Southwest Forestry College.
Diagnosis. The new species is closely related to S. bannaensis Niu et Zheng, 2005 and S. brachyptera sp. nov. as demonstrated by similar general appearance, but has following striking differences listed in Table 1 to distinguish the latter two.
Etymology. Named after its occurrence in the Mt. Laoyinshan (a noun in apposition), Gejiu.
Description. Male. Body small. Head almost as long as pronotum (3.7: 3.6mm), with short carinae and rugulae on surface (Figs. 1–2). Fastigium of vertex remarkably prominent forwards, apical margin rounded, lateral margin somewhat raised, length in front of eyes as long as width or 1.5 times larger than interocular distance. Vertex with a clear median longitudinal carina (Fig. 2). Face strongly oblique in profile. Frontal ridge narrow with longitudinal sulcus throughout; with lateral margins somewhat parallel above median ocellus, gradually broadening below it; lateral facial carinae straight. Gena nearly smooth. Antennae ensiform, 20 segments, backward touching coxa of hind leg; 3rd–11th segments prismatoidal, others laterally compressed nearly. All ocelli small. Eyes long oval, longitudinal diameter 1.7 times as long as horizontal one, and 1.2–1.3 times longer than subocular furrow. Pronotum with anterior margin nearly straight, posterior margin roundly angular; median carina distinct, only intersected by posterior sulcus; lateral carinae parallel; disc with irregular short carinae and rough points between lateral carinae; median and hind transverse sulci distinct; prozona 1.9 times as long as metazona (Fig. 2). Prosternum flat. Mesosternal lobes 1.2 times as wide as long; mesosternal interspace as long as minimum width; lateral lobes of metasterum evidently separate (Fig. 3). Brachypterous, tegmina touching each other in mid dorsal line, nearly reaching posterior margin of 3rd abdominal tergite, faintly longer than wings, apex narrowly rounded. Hind femur laterally compressed; upper carina weakly smooth; lower knee lobes roundly angular. Hind tibia with 11 external and 12 internal spines on dorsal side, external apical spine absent. Hind tarsi with arolium surpassing middle of claw. Tympana opening oval. Supra-anal plate triangular with median area raised, median longitudinal sulcus deep and apically subobsolete (Fig. 5). Cerci narrowly conical, not surpassing beyond apex of supra-anal plate. Subgenital plate short conical, apex obtuse. In dorsal view epiphallus with bridge arch-shaped, rectangular between bridge and lateral plate; anchorae apically further surpassing bridge; lateral plate with posterior projection pointing posteriad (Figs. 6–9).
Coloration. Body yellowish brown, but back of head, disc of pronotum, tegmen, knee of hind femur and hind tibia brown.
Measurements (mm). Length of body: male 18.5; length of pronotum: male 3.6; length of tegmen: male 5.0; length of hind femur: male 10.2.
Distribution. China: Yunnan (Gejiu).
Biology. Unknown.
