RESUMO
Spelaeobochica mahnerti sp. n., found in a limestone cave located in the municipality of Monjolos (Minas Gerais state, Southeastern Brazil), is described. It differs from congeneric species mainly by the rallum with 3 apically dentate blades, the position of the trichobothrium ib in the far distal half of the hand dorsum (near the base of fixed finger), the smooth subterminal setae, and by the arolia that are a little longer than the claws. A key to the species of Spelaeobochica is provided, as well as information on the habitat and threats for this new species. We further discuss troglomorphic traits in Brazilian species of Bochicidae.

Typhloroncus guatemalensis sp. n., found in Gruta de Lanquín, a limestone cave located in the municipality of Lanquín (Alta Verapaz, Guatemala), is described. It can be distinguished from the congeneric species mainly by the presence of lanceolate ventrodistal telotarsal setae on all legs; by the chelal teeth, which exhibit a varied morphology; by the number of trichobothria (30â32); and by its measurements. Typhloroncus guatemalensis sp. n. represents the first record for the genus in Guatemala and is considered to be troglobitic.

Spelaeobochica goliath sp. n., found in a limestone cave located in the municipality of Ibiracatu (Minas Gerais, Brazil), is described. It can be distinguished from the other species of the genus mainly by the slight angular shape of the anterior margin of the carapace, distal position of the trichobothrium est relative to st on the movable finger, isb in a position much nearer to level of sb than to that of esb, and by its pedipalpal measurements and proportions. It shares many morphological features with S. iuiu.
