All paratypes also bear the following label: “PARATYPE Perileptus pusilloides Deuve & Liang,
sp. nov. designated 2016” [yellow label].
TYPE LOCALITY.— China, Yunnan, Tengchong County, Hehua Township, 5.4 km S of Hehua
at Dengman village along Daying Jiang, N24.92346°/E98.38612°, 1105 m.
ETYMOLOGY.— The species epithet, pusilloides, is a combination of the species epithet,
pusillus, and the Greek suffix, –ειδής (transliterated into Latin as –oides), meaning resembling, in
reference to the similarity of members of this species to those of T.pusillus Jeannel (1923).
DIAGNOSIS.— Adults of this species (Fig. 6a) can be distinguished from those of all other
species in the region by the following combination of character states: size very small (BL = 2.3
mm), fully-winged; body color light yellowish brown, elytra concolorous throughout; microsculpture
of elytra irregularly isodiametric and moderately impressed; dorsal pubescence dense and
rather short; pronotum slightly transverse (ratio Pw/PL = 1.32) only slightly convex, with lateral
margins moderately rounded in anterior half, straightened just anterior to basal angles, the latter
acute and sharp but small, median basal area rugulose; elytra alutaceous, distinctly flattened, striae
finely punctate.
DESCRIPTION.— Size very small, BL = 2.3 mm. Color of dorsum pale yellowish brown, head
and pronotum slightly pale reddish in some specimens, appendages pale yellow, antennomeres 3 to
11 slightly darker yellowish brown; dorsal surface covered with dense but short pubescence.
Head. Relatively large, with eyes large and convex. Tempora very short. Frons flattened, nearly
smooth, shiny but finely punctate; frontal furrows arcuate and deeply impressed to posterior
margin of tempora; two pairs of supraorbital setae present and distinctly longer than setae of pubescence.
Labrum broad with apical margin distinctly emarginate or concave. Mandibles small, slender.
Mentum deeply concave, with median tooth broad and truncate. Submentum with a transverse
row of ten setae anteriorly. Gula broad. Antennae of moderate length, antennomeres 2 and 3 of
equal length.
Pronotum. Slightly transverse (ratio Pw/PL = 1.32) and flattened, widest at anterior onefourth,
with lateral margins markedly rounded anteriorly, less so posteriorly, briefly and deeply sinuate
just anterior to basal angles, the latter acute and sharp but small; basal margin projected posteriorly
as a short, truncate lobe medial to lateral sinuations. Disc moderately punctate, flattened
medially and slightly convex laterally; median basal area rugulose, only faintly defined anteriorly;
median longitudinal impression distinct throughout, narrow anteriorly, widened toward base. Lateral
margination slender throughout, slightly reflexed dorsally. One lateral seta (at anterior onefifth)
and one basolateral seta (on basal angle) present on each side.
Elytra. Alutaceous, moderately elongate, with humeri very distinct, rectangular but broadly
rounded; elytral disc flattened, only moderately convex laterally; lateral margination slender and
slightly reflexed dorsally; basal margin terminated medially at the origin of stria 5; striae 1 to 4 or
5 dinstinctly impressed and moderately punctate, striae 5 or 6 to 8 effaced. Recurrent stria absent.
Umbilicate setal series with setae of humeral group equidistance from each other, those of the
median group inserted posterior to middle.
Legs. Short. Male protarsomeres 1 and 2 dilated and apicomedially toothed.
Venter. Ventral surface of head and thoracic pleurae, prosternum, metasternum, metepisterna
and abdominal ventrites punctate. Pubescence denser on abdominal ventrites than on thoracic venter.
