Specimens studied. Holotype male. COLOMBIA. Huila, La Plata, Belén, Meremberg Natural Reserve , Meremberg Foundation Trail, 2º13’14.8”N: 76º07’41.0”W, 2418 m. 14.X.2018. R. González. On tree trunk . Paratypes: 2 males, same data as the holotype . 2 females, National Natural Park Los Guácharos, 1° 36’ 45.9’’N: 76° 06’ 15.4’’ W. 1882 m. 31.VII.2016. R. González. On tree trunk .

Etymology. This species is dedicated to Svanhild Büch, heir of the Meremberg Natural Reserve.

Remarks. This species is unique in the genus, in being the only species with macropterous and brachypterous females. The male phallosome shows similarities with that of Gojaoides spiculata Casasola González & García Aldrete.
