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.
剑角蟋属是泛热带剑角蟋科中物种最丰富的属。在其五个亚属中，安的列斯剑角蟋亚属最为多样，且是唯一分布于南美洲和安的列斯群岛的亚属。在本研究中，从巴西南部大西洋森林描述了剑角蟋属（安的列斯剑角蟋亚属）的两个新物种。新物种瓜拉凯拉巴剑角蟋（Xiphocentron gwarakeraba sp. nov.）的诊断特征为下附肢非常细长，无刺且具单一的中腹骨片；穆勒剑角蟋（X. muelleri sp. nov.）的诊断特征为下附肢腹缘向后延伸且明显截形。提供了阿夸卢梅剑角蟋（X. acqualume）、雅瓜雷剑角蟋（X. jaguare）、卡马坎剑角蟋（X. kamakan）和马拉卡南剑角蟋（X. maracanan）的新分布记录。还给出了雅瓜雷剑角蟋的其他非生殖器诊断特征，并描述了马拉卡南剑角蟋前翅叉Ⅱ（R3和R4）和雄性生殖器的种内形态变异。
