Abstract

A function for distinguishing between the long, intermediate and short-setaed forms of Mononychellus species complex is described. The results show that the dorsal-central body setae, variable D3, with a discriminant correlation coefficient of 0.99, was the most important variable. Five other variables, lengths of dorso-central body setae Dl, D2, laterals LI, L2 and propodosomal P2, which had significant discriminant correlations (0.28 to 0.35) with the function were, however, included in the discriminant function.

Résumé

La fonction décrite permet la distinction des formes à soies longues courtes ou intermédiaires des espèces du complexe Mononychellus. Les résultats prouvent que la soie dorso-médiane (variable D3) est de loin la plus importante, avec un coefficient de correlation discrimante de 0,99. Cinq autres variables-Dl, D2, Latérales Ll et L2 et propodosomale P2-présentant des coefficients de correlation discriminante significatifs (0,28 à 0,35) n'ont néanmoins pas été inclus dans la fonction.
