Mesabolivar huberi Machado et al., 2007a: 56 , figs 1–11 (♂♀, Brazil: Santa Catarina).

Type material. BRAZIL: Santa Catarina: ♂ holotype, 1♂ 2♀ paratypes, IBSP (62438–62441), Blumenau, Parque Natural Municipal Nascentes do Ribeirão Garcia (27°01’– 27°06’S, 49°04’– 49°10’W, 290–910 m a.s.l.), 23.i.2005 (holotype) and 18.iv.2004 (paratypes) (R.C. Francisco), not examined (according to Machado 2011, the types have been lost in the Butantan fire of May 2010) .

New records. BRAZIL: Santa Catarina: 3♂ 1♀, ZFMK (Ar 19206), Serra do Itajaí National Park (27.065°S, 49.098°W), 3a Vargem Trail, ~ 450 m a.s.l., 16.x.2014 (B.A. Huber, L.S. Carvalho) ; 2♀ in pure ethanol, ZFMK (Br 14-156), same data but 15.x.2014 . 1♀ in pure ethanol, ZFMK (Br 14-149), Serra do Itajaí National Park (27.058°S, 49.084°W), Chuva Trail, 300 m a.s.l., 15.x.2014 (B.A. Huber, L.S. Carvalho).

Description (amendments; see Machado et al. 2007a). Tibia 1 in three newly examined males: 4.4, 4.8, 4.9; in three females: 3.3, 3.4, 3.5. Male leg femora 3 slightly wider than others (diameters femora 1–4 in one male: 0.15, 0.15, 0.17, 0.14). Male eye measures: distance PME-PME 80 µm, diameter PME 100 µm, distance PME-ALE 80 µm, distance AME-AME 30 µm, diameter AME 25 µm. Epigynal processes in newly examined females variable but slightly shorter than shown in Machado et al. (2007a: fig. 10).

Natural history. The spiders were found in the same microhabitat as M. itajai , but apparently only within the ground, not in the leaf litter. When disturbed, they did not vibrate nor run away but just remained still.

Distribution. Known from type locality in Santa Catarina ( Brazil) only ( Fig. 738 ) (the new records above are within the range of coordinates given for the type specimens).
