Xiphocentron is the most species-rich genus of the pantropical family Xiphocentronidae. Among its five subgenera, Antillotrichia is the most diverse and the only one to occur in South America and Antilles. In the present study, two new species of Xiphocentron (Antillotrichia) are described from southern Atlantic Forest, Brazil. Xiphocentron gwarakeraba sp. nov. is diagnosed by the very elongate inferior appendage not bearing spines and with a simple mesal sclerite; X. muelleri sp. nov. is diagnosed by the inferior appendage with its ventral margin produced posterad and distinctly truncate. New distributional records are provided for X. acqualume, X. jaguare, X. kamakan, and X. maracanan. Additional non-genital diagnostic characters are presented for X. jaguare, and intraspecific morphological variations of forewing fork II (R3 and R4) and male genitalia are described for X. maracanan.

Three new species of Polycentropodidae (Insecta: Trichoptera) from the Northeast Region of Brazil are diagnosed, described, and illustrated. Polycentropus brevicornutus n. sp. of the Polycentropus gertschi Group can be diagnosed mainly by its much reduced, almost vestigial intermediate appendages, and by the inferior appendages, which are deltoid and very linear in lateral aspect. The two new species of Polyplectropus are P. anchorus n. sp. and P. auriplicatus n. sp. in the P. annulicornis and P. bredini Groups, respectively. Polyplectropus anchorus n. sp. is very similar to P. annulicornis Ulmer 1905, but can be distinguished from its congener mainly by the endothecal spines without setae and with their apices directed dorsolaterad. Polyplectropus auriplicatus n. sp. resembles P. brasilensis but can be distinguished mainly by the shorter and deltoid intermediate appendages, the straighter dorsolateral processes of the preanal appendages, and the inferior appendages each with its mesoventral branch more developed and rounded.

Two new species of Chimarra (Chimarrita) are described and illustrated, Chimarra (Chimarrita) mesodontasp. n. and Chimarra (Chimarrita) anticheirasp. n. from the Chimarra (Chimarrita) rosalesi and Chimarra (Chimarrita) simpliciforma species groups, respectively. The morphological variation of Chimarra (Curgia) morio is also illustrated. Chimarra (Otarrha) odonta and Chimarra (Chimarrita) kontilos are reported to occur in the northeast region of Brazil for the first time. An updated key is provided for males and females of the all species in the subgenus Chimarrita.

Two new species of Xiphocentron (Trichoptera: Xiphocentronidae) from Northeastern Brazil are diagnosed, described, and illustrated. Xiphocentron (Antillotrichia) kamakan n. sp. has inferior appendages each with a shape discontinuity (twist) between the first and second articles of inferior appendage, similar to that found in X. (Antillotrichia) rhamnes Schmid 1982, X. (Antillotrichia) serestus Schmid 1982, and X. (Antillotrichia) mnesteus Schmid 1982; however, it can be distinguished from these species by each inferior appendage having two darkly sclerotized spinulous regions ventrally on the basomesal and midmesal margins. Xiphocentron (Antillotrichia) maiteae n. sp. can be differentiated from all other congeners by having the basoventral margin of each inferior appendage strongly produced posterad. A key to males of Brazilian species of Xiphocentron is provided.
