Trechus thorongiensis Schmidt, 1994

( Fig. 12 )

Catalogue: Trechus thorongiensis Schmidt, 1994: 131 . Locus typicus: Central Nepal, Manang Distr., E-slope of Thorung La pass north of Annapurna Massif, altitude 4900–5200 m.

Type material: Holotype male, with label data “NEPAL-HIMALAYA, Annapurna Mts., 1993, leg. Schmidt”, “Thorong Pass, 8. VI., N Manang, E slope, 4900–5200 m ”, “ HOLOTYPUS Trechus thorongiensis des. J. Schmidt 1993” ( SMTD).

Paratypes: 126 specimen (males, females), with same label data as holotype ( BMNH, CCAS, CBALL, CBQ, CGITZ, CKAB, CLOR, CVT, CSCHM, CWR, NHMB, NME, SMTD, ZSM) .

Identification: See key above.

Relationships: According to derived aedeagal internal sac features T. thorongiensis Schmidt, 1994 is doubtless the sister species of T. eutrechoides (see above).

Distribution: Fig. 98 . Tibetan Himalaya of Manang Distr., Central Nepal. Hitherto only found on the eastern slope of the Thorung La pass, Muktinath Himal, north of Annapurna Massif.

Habitat: Higher alpine zone; vertical distribution approximately 4900–5000 m. On ascent to Thorung La pass the species was found along small humid depressions. The type locality is now completely built over by a complex of lodges for trekking tourists called ‘High Camp’ on the way to Thorung La pass.
