Mictacea, a New Order of Crustacea Peracarida

Journal of Crustacean Biology, 1985
ABSTRACT A new order, Mictacea, is proposed within the superorder Peracarida for Hirsutia bathyalis Sanders, Hessler, and Garner and Mictocaris halope Bowman and Iliffe. The new order is characterized by a unique combination of characters, most of which are not unique to the Mictacea, but are found in at least one other peracaridan order.

Evolutionary morphology of the circulatory system in Peracarida (Malacostraca; Crustacea)

Cladistics, 2010
AbstractWe demonstrate that by formulating guidelines for evolutionary morphology the transparency, reproducibility, and intersubject testability of evolutionary hypotheses based on morphological data can be enhanced. The five main steps in our concept of evolutionary morphology are (i) taxon sampling, (ii) structural analysis, (iii) character ...
