extended posteriorly to near basal margin, but not as close anteriorly to apical margin; basal foveae
small vaguely delimited; median basal area smooth, delimited laterally by short but deep and
oblique furrows; basal margin nearly straight, slightly sinuate. Lateral explanation moderately narrow
and slightly reflexed, widened posteriorly but not flattened. Midlateral pair of setae inserted
anterior to middle and basolateral pair inserted at hind angles.
Elytra. Moderately wide, elytral silhouette subovoid, humeri distinct but rounded, disc convex.
All discal striae evident and finely punctate, striae 1 to 4 moderately impressed, striae 5 to 8 more
faintly impressed, partially effaced, parascutellar striole rather long, recurrent stria deeply
impressed but abruptly terminated anteriorly, not connected with discal stria 5, intervals slightly
convex. Parascutellar setiferous pore present at base at common origin of discal striae 1 and 2. Two
discal seta (anterior and middle setae) present in stria 3, the anterior seta inserted within basal onesixth
of elytra, the middle seta inserted near elytral middle. Preapical seta also present, inserted on
interval 2 near stria 2, closer to sutural elytral margin than to apex. Umbilicate setal series with
setae of humeral group equidistant for each other and those of median group both inserted posterior
to middle of elytra.
Legs. Slender, moderately long. Protibiae furrowed, without anteroapical pubescence. Male
protarsi with tarsomeres 1 and 2 dilated and apicomedially toothed.
Abdomen. Ventrites each with a pair of paramedial setae, ventrite VII of males with a single
pair of paramedial apical setae, of females with two pairs.
Male aedeagus. Median lobe (Fig. 7b) long and slender, endophallus with a spoon-shaped sclerite.
COMMENTS.— Males of this species are most similar to those of A.wuyipeng in features of the
aedeagus; but they are smaller, their pronota distinctly narrower, more slender, and with much narrower
lateral margination, and the recurrent stria does not connect anteriorly with stria 5 as it does
in A.wuyipeng members.
HABITAT DISTRIBUTION.— The holotype specimen of this species was found under a stone on
moist substrate along a roadcut through an agricultural area formed in a large clearcut in what had
been mixed broadleaf evergreen and conifer forest at an elevation somewhere between 2300 and
2530 m (Fig. 36a). The paratype specimen was collected under stones on the shaded bank of the
Qiqi River just above the Forestry station at Qiqi at an elevation of 2000 m (Fig. 35b). Members
of no other Agonotrechus or other trechine species have been found syntopic with those of
A.fugongensis.
GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 7c. we examined a total
of 2 specimens (1 male and 1 female) from Fugong and Gongshan Counties, respectively (see Type
material above for exact collection data).
Specimens of this species were collected only in the northern half of the study area (Core
Areas 2 and 3) and only on the eastern side of the mountain range. This distribution pattern may
be an artifact of inadequate sampling on the western slope of the mountain range in the north, much
of which is in Myanmar. The geographical range of this species overlaps that of A.wuyipeng, but
members of the latter species appear to occupy slightly higher elevations in the same general areas.
OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from the
northern half of the Gaoligong Shan in western Yunnan Province, China.
