DEUVE ET AL.: CARABID BEETLE FAUNA OF THE GAOLIGONG MOUNTAINS 427
DIAGNOSIS.— Adults of this species (Fig. 33a) can be distinguished from those of all other
species in the region by the following combination of character states: size large (BL = 4.7 mm),
apterous; body color piceous, sutural and lateral elytral margins slightly paler, reddish; tempora
glabrous; median tooth of mentum apically truncate, almost bifurcate; antennae long; pronotum
slightly narrowed (ratio Pw/PL = 1.28), basal angles small, sharp, rectangular; elytra oblong,
slightly flattened along median suture, striae finely impressed, finely punctate, striae 1 to 2 or 3
more deeply impressed, more lateral striae more or less effaced but still evident, stria 5 not more
deeply impressed at its base; recurrent stria long, deeply impressed, abruptly terminated on interval
7; two discal setiferous pores present, inserted at anterior one-sixth and slightly posterior to
middle, respectively, on interval 3 near stria 3; preapical seta present, inserted 1.5 times as far from
apical elytral margin as from sutural margin.
DESCRIPTION.— Size large, BL = 4.7 mm. Body color dark piceous, head, basal and lateral
pronotal margins, and lateral and sutural margins of elytra more or less reddish, appendages paler
reddish brown, palpi yellowish brown, dorsum smooth, shiny with pronotum and elytra moderately
iridescent, head faintly alutaceous due to moderately impressed isodiametric microsculpture.
Head. Broad, slightly elongate. Eyes slightly convex, their diameter slightly less than twice
length of tempora, the latter short but distinctly convex. Frons convex, with frontal furrows sharply
impressed, not attenuated posterior to eyes. Two pairs of supraorbital setae present, the anterior pair
inserted in slight foveae. Clypeus with four setae. Labrum with six setae, anterior margin distinctly
concave. Right mandible (Fig. 16g) with premolar not fused with retinaculum but closely associated
with the latter, anterior tip of retinaculum enlarged as a distinct tooth and displaced anteriorly.
Mentum and submentum not fused. Mentum with medial tooth apically truncate, about onehalf
the length of the lateral lobes. Submentum with six setae anteriorly. Genae with a single ventral
seta one each side. Antennae moderate in length, with about 2.5 antennomeres extended posteriorly
beyond basal pronotal margin; antennomeres 3 and 4 about equal in length, antennomere 2
slightly shorter.
Pronotum. Slightly narrowed (ratio Pw/PL = 1.28), with greatest width anterior to middle,
only slightly narrowed posteriorly; lateral margins rounded, straightened for a short distance posteriorly,
then slightly sinuate just anterior to basal angles, the latter small, sharp and rectangular;
basal margin with median region slightly and convexly projected posteriorly. Disc convex, with
median longitudinal impression distinct, markedly deepened in median basal area, not extended
anteriorly to apical margin; basal foveae moderate in size and depth; median basal area delimited
laterally by a pair of short, oblique furrows, smooth except for a pair of paramedial longitudinal
foveae. Single midlateral setae on each side inserted anterior to middle; single basolateral seta on
each side, inserted at basal angle.
Elytra. Elongate ovoid, slightly narrowed anteriorly, humeri rounded and only slightly evident.
Disc moderately convex, slightly flattened in sutural area; striae finely impressed, finely punctate,
striae 1 to 2 or 3 more deeply impressed, more lateral striae more or less effaced but still evident,
stria 5 not more deeply impressed at its base. Parascutellar striole present, deeply impressed and
long. Recurrent stria long, deeply impressed, abruptly terminated on interval 7 slightly anterior to
the insertion point of preapical seta. Two discal setiferous pores present, inserted at anterior onesixth
and near middle, respectively, on interval 3 near stria 3. Preapical seta present, inserted 1.5
times as far from apical elytral margin as from sutural margin on interval 3 next to stria 2.
Legs. Short; protibiae with 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.
COMMENTS.— This species appears to be closely related to E.fortipes, but its members can be
