Paratypes (a total of 5): 3 males and 2 females (in CAS, IOZ, MNHN) labeled: same as holotype,
except first label “CASENT 1001920” to “CASENT 1001922” and “CASENT 1001924” to
“CASENT 1001925”, respectively. All paratypes also bear the following label: “PARATYPE

TYPE LOCALITY.— China, Yunnan, Gaoligong Shan, Lushui County, Pianma Township, 9.3
km ESE of Pianma, 25.99363°/ 98.66651°, 2460-2470 m.
DERIVATION OF SPECIES NAME.— The species epithet, uniporosa, is an adjective derived from
the Latin words, unus, meaning one, and porus, meaning pore or hole. The name refers to the single
discal setiferous pore found on the elytra of members of this species.
DIAGNOSIS.— Adults of this species (Fig. 28a) can be distinguished from those of all other
species in the region by the following combination of character states: size medium (BL = 3.3 to
3.5 mm), apterous; body color light brown, slightly iridescent; eyes small; tempora distinctly convex,
sparsely pubescent; pronotum transverse (ratio Pw/PL = 1.34), with basal angles obtuse and
rounded; elytra convex, with stria 1 deeply impressed and finely punctate, other striae more faintly
impressed and lateral striae effaced; recurrent stria terminated anteriorly in presumed location of
interval 6; only one discal setiferous pore present, inserted at anterior one-third next to stria 3;
preapical seta present, inserted next to stria 3; median lobe of male aedeagus (Fig. 28b) with apex
slender but bluntly rounded and slightly recurved dorsally, endophallus with a faintly sclerotized
scaly area.
DESCRIPTION.— Size medium BL = 3.3 to 3.5 mm. Body color light brown, appendages concolorous,
except palpi paler, dorsum shiny, slightly iridescent.
Head. Moderate in size, short; eyes small, not projected, their diameter about equal to length
of tempora but their convexity less than that of tempora, the latter markedly convex, inflated and
sparsely pubescent. Frontal furrows thin and linear, deeply impressed, arcuate, continuous posteriorly
to hind margins of tempora. Two pairs of supraorbital setae present, the anterior pair inserted
in foveae. Clypeus with four setae. Labrum with six setae, anterior margin distinctly concave or
emarginate. Mandibles short and slender, right mandible as in Fig. 16f. Mentum and submentum
not fused. Mentum with medial tooth apically truncate, about one-half the length of the lateral
lobes. Submentum with six setae anteriorly. Antennae rather short, not quite extended posteriorly
to basal one-fourth of the elytra, only 2.5 antennomeres extended posteriorly beyond basal pronotal
margin; antennomeres 2 and 3 about equal in length, antennomere 4 slightly shorter.
Pronotum. Distinctly transverse (ratio Pw/PL = 1.34), with greatest width near anterior onethird,
only slightly narrowed posteriorly; lateral margins rounded, slightly more so anteriorly,
slightly straighten just anterior to basal angles, the latter obtuse and rounded. Disc smooth and convex,
median longitudinal impression finely impressed, but continuous between anterior and posterior
margins; basal foveae shallow, faintly impressed; median basal area reduced, faintly delimited,
slightly punctate in some specimens. Basal margin nearly rectilinear. Lateral pronotal borders
moderately slender, regular, narrowly and regularly reflexed, lateral grooves narrow but distinctly
impressed. Single midlateral setae on each side inserted near anterior one-third; single basolateral
seta on each side, inserted at basal angle.
