Stock S.P. auteur aut IRD Caicedo A.M. auteur aut IRD Calatayud Paul-André auteur aut IRD text journalArticle eng text/pdf born digital access Rhabditis (Oscheius) colombiana n. sp. is described as a necromenic associate of the burrower bug Cyrtomenus bergi (Hemiptera: Cydnidae) collected in the Cauca Valley, Colombia. The new species resembles others of the insectivora-group, viz, Rhabditis (O.) insectivora Korner, 1954 and Rhabditis (O.) lucianii Maupas, 1919, in a number of morphological and life history traits, but can be separated by a combination of morphological and morphometric characters. The most distinctive morphological features that separate R. (O.) colombiana n. sp. from these two Rhabditis species are the total size of both males and females, which are much shorter and slimmer in the new species; the size of the male spicules and the values of ratios b and c. Additionally, molecular data (18S rDNA sequences) and phylogenetic analyses demonstrated the distinctiveness of this species when compared to a number of other Rhabditis (Oscheius) species. specialized description morphology molecular morphometrics taxonomy 076 7 3 363-373 2005 1388-5545 https://www.documentation.ird.fr/hor/fdi:010036726 10.1163/156854105774355590 1388-5545 [F B010036726] https://www.documentation.ird.fr/hor/fdi:010036726 https://www.documentation.ird.fr/intranet/publi/2023-03/010036726.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2006-03-29 2023-11-29 fdi:010036726 fre
