DIAGNOSIS. — Brujita n. gen. can be recognized from other Karosinae harvestmen by the following combination of characters: wide dorsal lobe at the frontal margin of prosoma, slightly elevated and rounded, no eyes; movable finger of chelicera with a basal blunt tooth; penis with MS A, B, C and D very long and with only a pair of small MS E in the middle flimsy lamina. Mictlana is the most similar genus to Brujita n. gen. , but the new genus can be differentiated from it by the absence of two dorsal lobes on prosoma, Brujita n. gen. having only the anterior one; and by the penis morphology, which in Mictlana is spear-shaped, with two pairs of short MS C and A respectively, and four pairs of small MS E (Cruz-López & Francke 2015: fig. 55A-C), whereas the penis of Brujita n. gen. is spoon-shaped, with two and four pairs of long MS C and A + B respectively and with only a pair of small MS E. ETYMOLOGY. — Brujita means ‘little witch’ in Spanish, feminine name taken from the song Brujita , written by the Spanish compositor and singer Nacho Vegas, gender feminine.
