The present study reports the occurrence of several specimens of the African caridean shrimp Lysmata uncicornis Holthuis and Maurin, 1952 in the NE Atlantic coast (Gulf of Cadiz, Spain and the Algarve, Portugal). Lysmata uncicornis is a poorly studied species that has been originally described from the Atlantic waters of Morocco, where it was first collected inside the port of Casablanca in a rocky bottom at 4-5 m depth. While no scientific publication has previously reported this species outside the waters of Morocco, several specimens have been collected in the coastal waters of the Gulf of Cadiz and the Algarve. This species may be able to expand successfully northward along European waters, probably favoured by global warming. It is possible that this expansion may also be enhanced through the marine aquarium trade. Recently, Lysmata arvoredensis Giraldes, Macedo, Brandão, Baeza and Freire, 2018 a new species of shrimp from the south coast of Brazil was described. However, morphological and genetic comparisons revealed no differences between L. uncicornis and L. arvoredensis. Therefore, L. arvoredensis should be considered as a junior synonym of L. uncicornis. While L. uncicornis may well be an amphi-Atlantic species, such as L. grabhami (Gordon 1935), for now, the introduction of L. uncicornis in Brazilian waters cannot be ruled out.

Abstract.A new species of Nycteliini from Chile is described, Callyntra cortesi nov. sp. Description of adults, photographies of morphologic characters, and a distribution map for the Callyntra species here mentioned are provided. Additionally, we discuss the morphological affinities of C. cortesi with related species.

Slow-release delivery systems are needed to ensure long-term sustained treatments for retinal diseases such as age-related macular degeneration and diabetic retinopathy, which are currently treated with anti-angiogenic agents that require frequent intraocular injections. These can cause serious co-morbidities for the patients and are far from providing the adequate drug/protein release rates and required pharmacokinetics to sustain prolonged efficacy. This review focuses on the use of hydrogels, particularly on temperature-responsive hydrogels as delivery vehicles for the intravitreal injection of retinal therapies, their advantages and disadvantages for intraocular administration, and the current advances in their use to treat retinal diseases.
