hospitalis Fraser, 1920 by having in the female a genital complex that is at least half the length of the cephalothoracic shield (including frontal plates) and with small, rounded posterolateral lobes, a 1-segmented abdomen that is less than one-quarter the length of the genital complex, a maxillule with two large tines on the dentiform process, a maxilliped without a myxal process, a pair of non-bifid tines on the sternal
furca, the spine on the first exopodal segment of leg 3 inserted distally on the basal swelling, a 3-segmented leg 4 exopod, and the inner lobe of leg 5 not protruding beyond the posterior margin of the genital complex.
straminea presenta dos autapomorfias: 6(3) membrana de la
furca subromboidal; 7(3) angulo de 100[grados] de inclinacion dei cuerpo de la
furca respecto dei tallo de la
furca; constituyen Ias autapomorfias que sustentan la especie.
Female: cibarium with about 12 horizontal small triangular teeth, one row of about 6 large vertical teeth and other row below of about four less differentiated teeth; arch complete but less visible at middle; spermathecae spherical smooth, without differentiated wide neck at the union with the individual spermathecal duct; individual spermathecal ducts as long as the
furca stem and nearly inexistent common duct (Ibanez-Bernal 2002).
lividus on the Brazilian coast from other grapsid species on the basis of three characteristics: (a) telson
furca with minute outer seta-like spines (type A); (b) fourth abdominal segment with minute medio-lateral process; and (c) fourth abdominal segment not laterally expanded.
In Cassidinae larvae, the
furca and shield are obvious defensive attributes positioned at the periphery.
