( Figs. 35 , 56 )

Catalogue: Trechus hodeberti Deuve, 1997: 141 . Locus typicus: Tibet, Largeh La, 5200 m (= Largen La or Lhachen La Pass north of Damzhung).

Type material: Not studied. Species identification is based on original description compared to additional material from locus typicus. T. hodeberti is characterized by highly complicated features of male genitalia which are figured in the original description and which allow an unambiguous diagnosis.

Additional material: CHINA: South Central Tibet: 2 males, 5 females, S Lhachen La, N Damzhung, 5150–5250 m, 30°38’20.2N 91°05’55.6E, 14.VII.07 ( CSCHM) .

Identification: See key above.

Relationships: See chapter Relationships of T. bastropi sp. n., below.

Distribution: Fig. 99 . Currently only known from the type locality, the Lhachen La pass of the central Nyainqentanglha Shan Massif, approximately 12 km northeast of Damzhung.

Habitat: Higher alpine zone; vertical distribution approximately 5100–5300 m. The specimens of the additional material were found under big stones on humid, gently inclined slopes.
