Diceraeus pulchricornis Walker, 1867: 250 (syn. by Rolston, 1976 ). Dichelops pulchricornis ; Distant, 1900: 431 ; Kirkaldy, 1909: 68 . Diagnosis Medium size (12.4). Humeral angles produced in a cylindrical spine, laterad directed. Male. Pygophore rectangular, almost as long as wide. Marginal process of dorsal rim triangular. Dorsal expansion of hypandrium narrow, apex obtuse. Apex of paramere enlarged, with apical and medial spines. Vesica in a narrow tube, slightly wider than ductus seminis. Female. Gonocoxites 8 quandrangular; posterior third of sutural margins divergent. Width at base of gonocoxites 9 nearly 2 times the width at apex. Posterior angle of laterotergites 8 strongly acute. Posterior angle of laterotergites 9 obtuse. Capsula seminalis processes: two reaching the posterior annular flange, one almost reaching the anterior annular flange. Distribution Brazil (DF new record, RJ, SP, SC, RS). Phylogenetic considerations Chloropepla vigens is the sister species of C. luteipennis , sharing the humeral angle produced into spine ( 10 ). Both species are extremely similar and the identification can be difficult.
