Abstract

A new species of Discocriconemella and the male of Discocriconemella degrissei are described from Minas Gerais state of Brazil. Discocriconemella mineira n. sp. differs from D. discolabia by having a longer stylet (61-71 vs. 35-47 [mu]m) and fewer body annuli (78-88 vs. 155-174), and from D. inarata by the longer stylet (61-71 vs. 51-61 {mu]m) and shorter body length (253-342 vs. 354-486 [mu]m). It differs from D. persae by having a shorter stylet, fewer body annuli, and a shorter post vulval body portion (Rv = 6-7 vs. 14-20). Discocriconemella mineira can be separated from D. degrissei by the head disc which is round in D. mineira and quadrilobate in D. degrissei. Males of D. degrissei resemble those of D. retroversa. Key words: Criconematidae, morphology, SEM, taxonomy.
