2A52E95D2D6B843AF5BC73CDFE479375.taxon	discussion	Remarks. Campylaspis bicurvata sp. nov. is most similar to C. chisamerai Petrescu, 2018 (Australia). Both species share the following features: pseudorostrum long and upturned; siphons relatively long; sides of carapace with two oblique ridges; areas A 1, A 2 (schematized in Fig. 1) well defined; frontal lobe with a transverse row of tubercles; dactylus of pereopod 2 with a digital process. Campylaspis bicurvata sp. nov. can be easily separated from C. chisamerai by having a well-defined A 3 (poorly defined in C. chisamerai) and a long eyelobe (short in C. chisamerai). Differences between Campylaspis bicurvata sp. nov. and C. chisamerai, and other similar species are listed in Table 1. The following morphological features are common to all these species: carapace with welldeveloped upper and lower ridges running obliquely backwards and defining the areas A 1 and A 2 when the anterior vertical ridge is present; posterior vertical ridge absent or poorly developed (except in C. undata); dorsal surface of carapace uneven due to the presence of many tubercles (except in C. exarata, which only has on a blunt prominence on each side of frontal lobe).	en	Duda, Maria Luiza De F., Roccatagliata, Daniel, Lucatelli, Debora, Souza- Filho, Jesser F.

2A52E95D2D6C8430F5BC73D4FEC09415.taxon	etymology	Etymology. After capsa (Latin: box), refers to the shape of the carapace, being dorsal and lateral surfaces quite flat, and the angle between them about 90 degrees.	en	Duda, Maria Luiza De F., Roccatagliata, Daniel, Lucatelli, Debora, Souza- Filho, Jesser F.

2A52E95D2D6C8430F5BC73D4FEC09415.taxon	discussion	Remarks. Campylaspis capsa sp. nov. is most similar to C. valida Jones, 1984 and C. nowrae Petrescu, 2006, in that in all three species the lateral depressed area is barely visible in the dorsal view. In C. capsa sp. nov. and C. valida the lower oblique ridge does not reach the end of the carapace. In turn, C. capsa sp. nov. has three dorsal transverse ridges and C. valida has two. In addition, five other species resemble C. capsa sp. nov., i. e., C. vitrea Calman, 1906; C. bulbosa Jones, 1974; C. ledoyeri Petrescu & Wittmann, 2003; C. alisae Corbera, 2008 and C. microsulcata Gerken, 2012. However, in all these species, (1) the sulci are distinctly visible in dorsal view and (2) the upper oblique ridges are connected with each other across the dorsal surface by a short transverse ridge at posterior third of carapace. This transverse ridge is absent in C. capsa sp. nov. and in C. valida, and apparently is also absent in C. nowrae. Differences between Campylaspis capsa sp. nov. and all the species above mentioned are shown in Table 2.	en	Duda, Maria Luiza De F., Roccatagliata, Daniel, Lucatelli, Debora, Souza- Filho, Jesser F.
