Resumo: The population structure of Phalloceros caudimaculatus was studied in a brook (sites A and B) existing in the CEDETEG - Guarapuava/PR. Fourteen length classes of 3 mm amplitude were defined for P. caudimaculatus. The widest length amplitude and the average and maximum sizes were observed in females. Females were significantly more predominant in the whole sample and more frequent in all length classes. The sexual proportion data, showed that the number of females was superior to that of males throughout most of the year. Young occurrence peaks were registered in November and March. Pregnant females were present from March to April, from July to August and in January, characterizing the reproductive season. At sampling site A, a higher occurrence of pregnant females and young was observed.
