Broteria 9: 150, 151. Original description. Trichacis meridionalis ( Brues) 1910 . Masner 1965 . Comb. n. in: Psyche 1: 303. Diagnosis. Trichacis meridionalis ( Brues 1910 ) has: antennal scape, pedicel and leg including coxa except tips of hind femur and tibia reddish or ferruginous; vertex and occiput smooth and shining, separated by “a distinct raised line” [= hyperoccipital carina]; ocelli in triangle, lateral ones slightly nearer to eye margin than to median ocellus [= OOL <LOL]; T1 as wide as long. The type was collected in Brazil . Lectotype and paralectotype females were deposited at the Museum of Comparative Zoology, Harvard University, USA . Of the 27 Neotropical species (including those described in this paper), only Trichacis proximata n. sp. and T. acarinata n. sp. have also a smooth vertex. T. acarinata differs from T. meridionalis and T. proximata by hyperoccipital carina absent and T1 longer than wide. T. proximata differs from T. meridionalis by OOL> LOL and T1 shorter than wide.
