Planche 2 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. chilensis, M. dubioides, M. fosshageni, reticulata, dubia, Cymbasoma gracilis, M. ferrari, M. zernovi, M; angustipes, Monstrillopsis sp.
For Suarez-Morales & al. (2006, p.104), the inclusion in this genus seems to be correct: 4 caudal setae, well developed eyes, absence of P5, 3 postgenital somites, and a proximal hyaline lobulated process on the distal antennular segment After Lee J. & al. (2016, p.421), male genitalia with a relatively short median shaft with its posterolateral corners extended as elongate lappets belong subgroup ''Type II'' (Suarez-Morales & McKinnon, 2014).
