DEUVE ET AL.: CARABID BEETLE FAUNA OF THE GAOLIGONG MOUNTAINS 387
derived from the name of the township in which the type locality is located, Shiyueliang. This is
the current name for the former Lishadi township.
DIAGNOSIS.— Adults of this species (Fig. 18a) can be distinguished from those of all other
species in the region by the following combination of character states: size relatively large (BL =
4.0 to 4.2 mm), apterous; body color reddish-brown; head slightly elongate; tempora glabrous;
pronotum moderately transverse (ratio Pw/PL = 1.42); elytra with striae not or faintly punctate,
recurrent stria continuous anteriorly with stria 5, two discal setae present and inserted next to stria
3, preapical seta present and inserted next to stria 2 in forward position near apical one-fourth of
elytra; median lobe of male aedeagus with apex thin and faintly reflexed dorsally in lateral view
(Fig. 18b), endophallus with only a single, small thin elongate sclerite.
DESCRIPTION.— Size relatively large, BL = 4.0 to 4.2 mm. Body color reddish-brown, shiny,
appendages slightly paler. Body surface smooth, head capsule finely alutaceous.
Head. Moderate in size, slightly elongate and thick; eyes small and moderately convex, their
diameter about 1.5 times as long as tempora, the latter short, moderately convex and glabrous.
Frons slightly flattened; frontal furrows deep, rounded, slightly attenuated posterior to the eyes.
Two pairs of supraorbital setae present, the anterior pair inserted in foveae. Clypeus with four setae.
Labrum with six setae, anterior margin distinctly concave. Mandibles short; right mandible tridentate
with middle tooth closer to basal tooth (premolar) than to distal tooth. Mentum and submentum
not fully fused but nearly so, suture between them only faintly impressed. Mentum with medial
tooth apically truncate, less than one-half the length of the lateral lobes. Submentum with six
setae anteriorly, swollen anteriorly. Gula wide. Genae with a single seta ventrally on each side.
Antennae short, with less than two antennomeres extended posteriorly beyond basal pronotal margin;
antennomeres 3 and 4 slightly longer than antennomere 2.
Pronotum. Moderately transverse (ratio Pw/PL = 1.42), narrowed posteriorly, greatest width
near anterior one-third; lateral margins markedly rounded, straightened only just anterior to small,
rectangular and sharp basal angles. Disc convex, smooth and glabrous, median longitudinal
impression deeply impressed, interrupted anteriorly a short distance from anterior margin; basal
foveae distinct; median basal area with several faint, irregular, punctiform depressions, delimited
laterally by oblique furrows. Lateral borders of pronotum moderately slender, regular, slightly
reflexed, lateral grooves deeply impressed. Single midlateral setae on each side inserted at anterior
one-third; single basolateral seta on each side, inserted slightly anterior to apex of basal angle.
Elytra. Ovoid, humeri distinct but rounded. Disc convex and smooth. Striae not or only faintly
punctate, striae 1 to 5 deeply impressed, striae 6 to 8 very faintly impressed but evident. Parascutellar
striole present. Recurrent stria continuous anteriorly with stria 5. 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 on
interval 3 next to stria 2 in forward position near apical one-fourth of elytra.
Umbilicate setal series with setae of humeral group equidistance from each other and setae of
median group inserted slightly posterior to middle.
Legs. Short, protibiae with longitudinal furrow. Male protarsomeres 1 and 2 dilated and apicomedially
toothed.
Abdomen. Abdominal ventrites glabrous, except for a single paramedial seta on each side, and
ventrite VII of males apically with one pair of paramedial setae, of females with two pairs.
Male aedeagus. Median lobe (Fig. 18b) moderately broad basally with sagittal aileron present
and moderate in size; shaft gradually narrowed toward apex; apical lamella short, rectilinear,
extremely thin and slightly recurved dorsally in lateral view; endophallus with a single thin and
elongate sclerite.
