Trechepaphiopsis unisetulosa Deuve & Kavanaugh, sp. nov. designated 2016” [yellow label].
TYPE LOCALITY.— China, Yunnan, Fugong County, Shiyueliang Township, 0.2 km w of
Shibali, N27.16650°/E098.77936°, 2537 m,
DERIVATION OF SPECIES NAME.— The species epithet, unisetulosa, is an adjective derived from
the Latin words, unus, meaning one, and setulosus, meaning bearing bristles or setae. The name
refers to the single discal seta found on the elytra of members of this species.
DIAGNOSIS.— Adults of this species (Fig. 29a) can be distinguished from those of all other
species in the region by the following combination of character states: size small to medium (BL
= 3.3 to 3.5 mm), apterous; body color dark reddish brown, dorsum shiny, very slightly iridescent;
eyes small, only slightly projected laterally; tempora convex and sparsely pubescent; pronotum
transverse (ratio Pw/PL = 1.40), with basal angles obtuse and rounded; elytra convex, with medial
three or four stria distinct, finely punctate, more lateral striae more or less effaced; recurrent stria
terminated anteriorly in presumed location of interval 6; only one discal setiferous pore present,
inserted near anterior one-third next to stria 3; preapical seta present, inserted next to stria 2; median
lobe of male aedeagus (Fig. 29b) with apex lobated and broadly rounded; endophallus with a
large, scaly sclerorized area.
DESCRIPTION.— Size small to medium, BL = 3.3 to 3.5 mm. Body color dark reddish brown,
interval 1 of elytra slightly paler, reddish, appendages yellowish brown, palpi paler yellow; dorsum
smooth, pronotum and elytra shiny, very slightly iridescent, head slightly alutaceous from more
deeply impressed isodiametric microsculpture.
Head. Rather broad; eyes small, only slightly projected laterally, their diameter about equal to
length of tempora, the latter convex and sparsely pubescent. Frons convex, with frontal furrows
evenly rounded and deeply impressed, continuous to posterior 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 emarginate. Mentum and submentum not fused. Mentum
with medial tooth broad and apically bifid, less than half the length of the lateral lobes. Submentum
with six setae anteriorly. Gula broad. Genae with a single ventral seta one each side. Antennae
short, with only about 1.5 antennomeres extended posteriorly beyond basal pronotal margin; antennomeres
2 and 4 about equal in length, antennomere 3 slightly longer.
Pronotum. Transverse (ratio Pw/PL = 1.40), with greatest width near anterior one-third, moderately
narrowed posteriorly; lateral margins rounded, slightly more so anteriorly, slightly straighten,
but not at all sinuate, just anterior to basal angles, the latter bluntly obtuse. Disc convex, median
longitudinal impression finely impressed, continuous from posterior side of apical median
swelling to posterior margin; basal foveae shallow, faintly impressed; median basal area well
defined but short and transverse. Lateral borders slender and finely relexed dorsally, lateral grooves
deeply impressed. Single midlateral setae on each side inserted near anterior one-third; single basolateral
seta on each side, inserted at basal angle.
