Minutotrechus minutus ( Uéno, 1997)

( Figs. 11 , 46–48 )

Stevensius minutus Uéno, 1997:182 . Holotype, a female, in NMST. Type locality: China, Yunnan, Gaoligong

Shan, Tengchong County, Dabei , 2430 m. Minutotrechus minutus (Uéno) NEW COMBINATION .

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 .
