Planche 1 Issued from : E. Suarez-Morales, A. Bello-Smith & S. Palma in Zool. Anz., 2006, 245. [p.103, Table 1]. Structural characteristics. Morphological characters for comparative morphology of the species assigned to the genus Monstrillopsis by different authorities. See : M. dubioides, M. fosshageni, M. reticulata, M. sarsi, Cymbasoma gracilis, M. ferrari, M. dubia, M. angustipes, Monstrillopsis sp.
Key for the identification of the currently known species of Monstrillopsis (female only) after Suarez-Morales & al. (2006, p.105): 1 - Outer lobe of P5 without distal elongation; last antennular segment less than 45% of A1 length; body length less than 3 mm. .... 2. 2 - 5th pedigerous somite with lateral margins straight; genital somite not expanded proximally; A1 representing more than 30% of total body length; 5 caudal setae.
For Suarez-Morale & al. (2006, p.104), this species from the Black Sea represents an enigmatic form. The female has most of the characters of the genus (sensu Sars, 1921) except the most important: the presence of 4 caudal setae. The authors have proposed to retain this species as an aberrant form of Monstrillopsis until new confirmation.
