DEUVE ET AL.: CARABID BEETLE FAUNA OF THE GAOLIGONG MOUNTAINS 365
NOTES ON TYPE MATERIAL.— we have not had an opportunity to study the holotype of this
species, but we have examined a paratype female deposited in IOZ. Features noted below are based
on our examination of that paratype and Uéno’s orginal description.
DIAGNOSIS.— Adults of this species (Fig. 11a), the only known species in this new genus, can
be distinguished from those of all other species in the region by the combination of character states
noted in the generic diagnosis.
HABITAT DISTRIBUTION.— According to Uéno (1997) specimens of the type series were collected
at an elevation of 2430 m in a dense Rhododendron forest by sifting moist leaf litter accumulations
on the ground. He also noted that many specimens of “Trechus asetosus Uéno” (1997)
were also collected in the same litter samples.
GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 11b. This species is
known only from the six female specimens of the type series collected at the type locality, in Tengchong
County, high on the western slope of the southern part of the Gaoligong Shan in Core
Area 6.
OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from the type
locality in the southern part of the Gaoligong Shan, in western Yunnan Province, China.
Genus Queinnectrechus Deuve, 1992
Queinnectrechus Deuve, 1992b:354.
TYPE SPECIES.— Queinnectrechus excentricus Deuve, 1992a
DIAGNOSIS.— Adults of this genus (Figs. 12–14) can be recognized by the following combination
of character states: size moderate (BL = 3.5 to 4.8 mm), apterous, body dark, reddish brown
to piceous, surface micaceous; head with small eyes, mentum and submentum fused; right
mandible tridentate, the premolar tooth distinct but joined with the retinaculum (see Deuve 1992b,
Fig. 23); pronotum cordiform and markedly convex, lateral margination effaced posteriorly, with
two setae (midlateral and basolateral) present on each side; elytra markedly convex, inflated,
slightly tear-shaped, humeri effaced, elytral discal striae absent or vestigial, with two (in most
members) or three (in a few members) discal setae present, aligned on interval 3 near stria 3,
preapical seta absent from most members, in some of these members inserted forward in a subdiscal
position, in very few placed in typical trechine position nearer elytral apex and next to stria 2;
protibiae furrowed; abdominal ventrites IV to VI glabrous except for a single pair of paramedial
setae; endophallus of male aedeagus with two sclerites.
COMMENTS.— Two new genera closely related to Queinnectrechus have recently been
described. Members of Dactylotrechus Belousov and Kabak (2003) are distinguished by the supernumerary
setae present on the external margins of the pronotum and on more lateral areas of the
elytral disc. Members of Puertrechus Belousov and Kabak (2014a) are distinguished by the presence
of a single discal setae subbasally on interval 5. Members of both taxa have a preapical seta
inserted near stria 2, a plesiomorphic feature among trechines. Taxonomic limits and phylogenetic
relationships among the “genera” Stevensius, Kozlovites Jeannel (1935), Queinnectrechus, Dactylotrechus,
Puertrechus, Sinotrechiama Uéno (2000), Uenoites Belousov and Kabak (2016) and
Minutotrechus (describe above) are still poorly resolved. This is why we describe below a new
taxon, Gaoligongtrechus, provisionally with the rank of subgenus. This assignment can be changed
as needed in the future.
GEOGRAPHICAL DISTRIBUTION.— This genus, which currently include 13 described species
(Belousov and Kabak 2003, Casalle and Magrini 2009, Deuve 1992a, and Uéno 1998a and 1998b)
is currently known from the Min Shan region of northern Sichuan Province southwest to western
