DERIVATION
OF
SPECIES
NAME
.— The species epithet,
pseudoqiqiensis
, is a combination of the Greek prefix,
ψΕυδής
(translated into Latin as
pseudo-
) meaning false, and the species epithet,
qiqiensis
, in reference to the similarity of the unique
holotype
female of this species to members of
T. qiqiensis
.
DIAGNOSIS
.— Adults of this species (
Fig. 21a
) can be distinguished from those of all other species in the region by the following combination of character states: similar to
T. qiqiensis
in size (BL = 4.0 mm) and most features, except body color paler, more reddish; elytral striae more faintly punctate, almost impunctate toward elytral apex, more deeply impressed on center of disc and not attenuated near apex, recurrent stria less abruptly interrupted by a convexity and nearly continuous anteriorly with stria 7; preapical seta present and inserted on interval 3 next to stria 2 near apical one-fourth of elytra.
DESCRIPTION
.— Size relatively large (BL = 4.0 mm). Body color bright brownish red, shiny, appendages yellowish-tan, palpi pale yellow.
Head. Moderate in size; eyes slightly convex, their diameter about 1.5 times as long as tempora, the latter short, convex and glabrous. Frons not flattened; frontal furrows deep, rounded, not or only slightly attenuated posterior to the eyes. Two pairs of supraorbital setae present, the anteri- or pair inserted in foveae. Clypeus with four setae. Labrum with six setae, anterior margin distinctly concave.
Mentum
and submentum not fused.
Mentum
distinctly concave at middle, with medial tooth broad and apex slightly bifid, about one-half the length of the lateral lobes. Submentum with six setae anteriorly. Gula wide. Genae with a single seta ventrally on each side. Antennae short, with about 2 antennomeres extended posteriorly beyond basal pronotal margin; antennomeres 2 and 4 about equal in length, antennomere 3 slightly longer.
Pronotum. Transverse (ratio PW/PL = 1.45), slightly narrowed posteriorly, greatest width near anterior one-third; lateral margins broadly rounded, not sinuate subbasally, straightened only immediately anterior to basal angles, the latter small and rectangular. Disc convex, smooth and glabrous, median longitudinal impression finely impressed, interrupted slightly posterior to anteri- or margin but extended to basal margin; basal foveae distinct, but shallower and slightly convex at center; median basal area mainly smooth, but with several small foveae anteriorly near the posterior transverse impression. Basal margin rounded and slightly projected medially. Lateral borders of pronotum slender, narrowly reflexed, lateral grooves distinctly impressed. Single midlateral setae on each side inserted near anterior one-third; single basolateral seta on each side, inserted at basal angle.
Elytra. Ovoid and only slightly elongate, humeri not very broad but rounded. Disc convex and smooth. Striae very finely punctate, nearly smooth in apical half, intervals moderately convex; striae 1 to 4 deeply impressed and not attenuated apically, stria 5 to 8 successively more faintly impressed by still evident. Parascutellar striole present, short. Recurrent stria less abruptly interrupted by a convexity and nearly continuous anteriorly with stria 7. Basal setiferous pore present at common origin of striae 1 and 2. Two discal setae present and inserted next to stria 3, one at anterior one-fourth and one near middle of elytra. Preapical seta present and inserted in a discal position on interval 3 next to stria
2 in
forward position at apical one-fourth of elytra. Umbilicate setal series with setae of humeral group equidistance from each other and setae of median group insert- ed slightly posterior to middle.

T. pseudoqiqiensis
in the Gaoligong Shan region. Scale lines a = 0.5mm, b = 100 km.
Legs. Slightly short, protibiae with only a faint longitudinal furrow.
Abdomen. Abdominal ventrites glabrous, except for a single paramedial seta on each side, and ventrite VII of female apically with two pairs of paramedial setae.
HABITAT
DISTRIBUTION
.— The unique
holotype
female of this species was found under a stone in an open area cleared of forest but surrounded by bamboo thickets and scattered
Abies
,
Rhododendron
and
Prunus
species
at an elevation of
3290 m
(
Fig. 42b
).
One specimen
of
Trechus shibalicus
sp. nov.
also was found at the same site.
