Being considered as an endangered species at the national level, the new locality for this gecko constitutes an opportunity for its conservation. Some topics regarding the possible origins of this new population are discussed.

Background. The Gracilariaceae is one of the most diverse and abundant families of marine red algae. Most species in this family exhibit high morphological variability and overlapping of characters. In the Yucatan Peninsula 30 species have been historically recorded, but the phylogenetic identity for many of them is still unknown. Questions: Is the current diversity of the family in the area overestimated? Studied species: Crassiphycus caudatus, C. corneus, C. usneoides, Gracilaria flabelliformis, G. hayi, G. cf isabellana, G. microcarpa, G. occidentalis, G. suzanneae, Gracilariopsis tenuifrons. Study site and dates: Campeche: km 33 carretera Champotón, Bahía Tortuga, Puente Xen Kan III, Punta Xen, Sabancuy, 2017, 2018; Yucatan: Puerto Sisal, Puerto Progreso, Puerto Chicxulub, Puerto Telchac, 2018; Quintana Roo: Playa 88, Xcalacoco, Punta Esmeralda, 2019. Methods. Phylogenetic analysis (with COI-5P and rbcL sequences), supported by DNA species delimitation methods, genetic distances and morphological comparisons, allowed us to molecularly identify the specimens collected. Results. The phylogenetic identity of 10 species of Gracilariaceae was confirmed, two of which are new records for the Mexican Atlantic: G. hayi and G. suzanneae. Conclusion. The study demonstrated that the molecular assessment has proved to be very useful for the diversity evaluation, thus, the future phylogenetic identifies for the rest of morphospecies recorded in the area will allow a better approximation of Gracilariaceae diversity species.

Fifty species of sea lice, members of the family Caligidae, were collected from the marine fishes of Moreton Bay, Queensland, during two workshops held in 2016. Only 21 of these species had previously been reported from Australian waters: of the remaining 29 species, 13 are new to science and another 16 are recorded from Australia for the first time. An illustrated differential diagnosis is presented for well known species; but for new or poorly known species a full description is provided. The 13 new species are: Anuretes amplus sp. nov. and A. amymichaelae sp. nov., both from Diagramma pictum (Thunberg, 1792); Caligus abigailae sp. nov. from Sphyraena obtusata Cuvier, 1829; C. elasmobranchi sp. nov. from Himantura uarnak (Gmelin, 1789), H. toshi Whitley, 1939, Dasyatis fluviorum Ogilby, 1908, Aetobatus ocellatus (Kuhl, 1823) and Pastinachus atrus (Macleay, 1883); C. hyporhamphi sp. nov. from Hyporhamphus quoyi (Valenciennes, 1847); C. nataliae sp. nov. from Herklotsichthys castelnaui (Ogilby, 1897) and Neoarius graeffei (Kner & Steindachner, 1867); C. neoaricolus sp. nov. and C. paranengai sp. nov. both from Neoarius graeffei; C. pseudorhombi sp. nov. from Pseudorhombus arsius (Hamilton, 1822); C. turbidus sp. nov. from Tripodichthys angustifrons (Hollard, 1854); C. upenei sp. nov. from Upeneus tragula Richardson, 1846; Lepeophtheirus robertae sp. nov. from Scarus ghobbhan Forsskål, 1775 and Pupulina keiri sp. nov. from Aetobatus ocellatus. The rare species Caligodes alatus Heegaard, 1945 is redescribed and transferred to the genus Caligus Müller, 1785, but requires a replacement name due to secondary homonymy: Caligus alepicolus nom. nov. is proposed. Similarly, Parapetalus spinosus Byrnes, 1986 is redescribed and transferred to the genus Caligus where it becomes a secondary homonym: the replacement name Caligus seriolicolus nom. nov. is proposed. Five large species-groups within the genus Caligus are recognised here on the basis of suites of morphological character states. They are based around the following species: C. bonito Wilson, 1905, C. confusus Pillai, 1961, C. diaphanus von Nordmann, 1832, C. macarovi Gusev, 1951 and C. productus Dana, 1852. These species-groups can be used to navigate this relatively large genus, but their monophyletic status should not be assumed.

First Time

Amaranthaceae s.s. (Caryophyllales) is a cosmopolitan family well represented in the Yucatan Peninsula Biotic Province (YPBP). The YPBP is a biogeographic area that comprises entirely three Mexican states (Campeche, Quintana Roo, and Yucatan), partially two Mexican states (Chiapas and Tabasco), northern Belize, and northern Guatemala (Petén department). Most of the available checklists of the vascular plants from the Yucatan Peninsula (YP) merely include taxa from the Mexican states of Campeche, Quintana Roo, and Yucatan. A study of the Amaranthaceae diversity in the YPBP in its expanded delimitation is here presented for the first time, on the basis of field surveys and examinations of the specimens kept in the main Mexican herbaria (CICY, ENCB and MEXU). Accepted names, main synonyms, morphological descriptions, phenology, habitat, elevation, ethnobotanical uses, vernacular Spanish and Mayan names, origin status, and digital illustrations are provided for each taxon. Keys of identification are also given. Each taxon was geographically mapped using ArcGIS software. Notes about diversity and distribution analyses were conducted comparing maps of distribution for each taxon considering vegetation types and climatic types characterizing the YPBP. A total of 28 species (with 4 varieties) representing nine genera of Amaranthaceae s.s. (excluding Iresine) ocurring in the YPBP were studied. An estimate of the family diversity in the YPBP is increased here, as records of four new taxa are presented for this region. Results suggest that most of the taxa are natives, aliens, and/or weeds mostly occupying perturbed vegetation types. Only Blutaparon vermiculare, Amaranthus greggii, and A. arenicola show affinity to sand dunes primary vegetation. This new information about the distribution of Amaranthaceae s.s. in the YPBP, considering its invasion and origin status, can help to develop further studies focused on conservative approaching to know more about natural biogeographic regions such as YPBP.

Abstract A new stygobitic isopod from the anchialine systems of the Yucatan Peninsula, Mexico, is described, bringing the total number of anchialine isopods to seven. Curassanthura yucatanensis sp. nov. of the family Leptanthuridae is the first species of the genus to be recorded from a continental site. It can be distinguished from the other known species in the genus by the shape of the head, wider than long, and the number of robust setae (30) on the palmar margin of the propodus of pereopod 1.
