Most Late Cretaceous Phoenicopsis leaves lack preserved cuticle and so have been determined as Phoenicopsis ex gr. angustifolia, P. ex gr. speciosa or Phoenicopsis sp. using only macromorphology. We studied the epidermal characters of leaves from the Santonian-Campanian Emuneret Formation of the Enmy-vaam River Basin in Chukotka, Northeastern Russia. Based on this study, here we describe a new species, P. chukotkensis sp. nov., revealing unique morphological and epidermal features. It possesses stomata arranged in bands on one leaf surface and in rows on another and hence belongs to the subgenus Windwardia. This is the first find of the subgenus Windwardia in the Late Cretaceous. Analysis of the Cretaceous Phoenicopsis distribution reveals that remains of Phoenicopsis leaves are not numerous in the Western Hemisphere, where it is known only in the Albian of Western Canada and Albian-Cenomanian of Northern Alaska. In the Eastern Hemisphere, Phoenicopsis occurrences are sporadic in the Lower Cretaceous of western Eurasia, where bundles of Phoenicopsis leaves have been found in England, West Spitsbergen, Franz Josef Land, the Middle Urals and Western Kazakhstan. Abundant Early Cretaceous remains of Phoenicopsis have been reported in Eastern and Northeastern Asia. In the Upper Cretaceous of the Eastern Hemisphere, Phoenicopsis is known only in Northeastern Russia and the Russian Far East. Most likely, plants with Phoenicopsis foliage retreated from the south due to the late Albian aridization across Central Asia. They persisted in cooler and wetter conditions of higher palaeolatitudes where the palaeoclimate was similar to a modern humid temperate one. (C) 2020 Elsevier Ltd. All rights reserved.

The Einasleigh Uplands biolegion of central north Queensland, Australia, harbours a unique suite of reptiles that have begun to receive significant attention in the last 20 years. This has resulted in a number of new reptile species being described, and recognition that others await description. We describe a new species of Lucasium Wermuth, 1965 from the western Einasleigh Uplands. Lucasium iris sp. nov. is genetically distinct and morphologically diagnosable from all congeners by its large size, long and narrow tail, nares in contact with rostral scale, homogeneous body scales, distinct vertebral stripe. and paired, enlarged, apical subdigital lamellae. It is known from low rocky hills in a localised area of the Gregory Range, has the most restricted known distribution of any Lucasium, and is the only Lucasium endemic to Queensland. The new species appears most closely related to L. steindachneri (Boulenger, 1885), based on mitochondrial DNA sequences, but has a colour-pattern more similar to L. immaculatum Storr, 1988. All three of these species occur in the Einasleigh Uplands, but only L. steindachneri is known to occur in sympatry with L. iris sp. nov. In addition to the description of the new species, we present records of Lucasium immaculatum from the Einasleigh Uplands, which represent a significant known range extension.
