Abstract
Holo- and paratypes of the root-knot nematodes Meloidogyne mayaguensis Rammah & Hirschmann, 1988 and Meloidogyne enterolobii Yang & Eisenback, 1983 were morphometrically and morphologically compared. All observed female, male and second-stage juvenile morphometrical and morphological characters are identical for the two studied species. Additionally, contradictions between the original species descriptions were unravelled.The present study of holo- and paratypes confirms the taxonomical status of Meloidogyne mayaguensis as a junior synonym for Meloidogyne enterolobii.
Highlights
In 1983 Yang and Eisenback described the root-knot nematode Meloidogyne enterolobii from roots of pacara earpod trees (Enterolobium contortisiliquum (Vell.) Morong), on Hainan Island in China
The authors reported (1996) on M. enterolobii: “M. enterolobii from China has been described as having the same esterase phenotype as M. mayaguensis
Taxonomical not strictly necessary, we present a morphological and morphometrical comparison between the holo- and paratype slides of M. mayaguensis and M. enterolobii
Summary
In 1983 Yang and Eisenback described the root-knot nematode Meloidogyne enterolobii from roots of pacara earpod trees (Enterolobium contortisiliquum (Vell.) Morong), on Hainan Island in China. Are in good condition and includes female holotypes, male allotypes, perineal patterns and second-stage juvenile paratypes. The important morphological characters, like female stylet knob and perineal pattern shape do not differ between the species, as can already be observed by comparing the original illustrations between M. mayaguensis and M. enterolobii (see original descriptions respectively Fig. 2 A–D & Fig. 3 A–D).
