Última Scanning electron microscopy of acrothoracican cypris larvae (Crustacea, Thecostraca, Cirripedia, Acrothoracica, Lithoglyptidae) Naturalis Kolbasov, Gregory A.; Høeg, Jens T.; Elfimov, Alexei S.. Scanning electron microscopy was used to provide a full morphological description of cypris morphology in the acrothoracican species Lithoglyptes milis and L. habei (Lithoglyptidae). Special attention was given to lattice organs, antennules, thorax, thoracopods, abdomen, and furcal rami. Cypris larvae of the Acrothoracica share some putative plesiomorphic features with the cypris-like ascothoracid larvae of the non-cirripede taxon Ascothoracida. The most notable are traces of abdominal segmentation and carapace lattice organs without pore fields. Acrothoracican cyprids also share numerous synapomorphies with those of the Thoracica and the Rhizocephala. This list includes a four-segmented antennule with a triangular first segment of two sclerites set at an...

Ano: 1999 URL: http://www.repository.naturalis.nl/record/534290 Larval development of Notolopas brasiliensis Miers, 1886 (Brachyura: Majoidea: Pisidae) described from laboratory reared material and a reappraisal of the characters of Pisidae Pap. Avulsos de Zool. (São Paulo) Santana,William; Marques,Fernando P.L.; Fransozo,Adilson; Bertini,Giovana. The complete larval stages of Notolopas brasiliensis are described from laboratory reared material, with emphasis on the external morphological features of Majoidea, and compare the morphology of N. brasiliensis with other genera of Pisidae. Larval development of N. brasiliensis consists of two zoeal stages and one megalopa. The duration mean of each zoeal stage was 4.2 ± 1.0 days for Zoea I and 3.8 ± 0.7 days for Zoea II, the megalopa instar appearing 8.1 ± 0.4 days after hatching. The characters previously used to define larval forms of Pisidae are either symplesiomorphic or potentially highly homoplastic. As well, was observed that there are no common sets of larval characters that would define Pisidae nowadays. However, was showed that only a...
