Iberia has one of the richest bee faunas in the world, and the genus Andrena is no exception with around 200 species known from the Peninsula. The fauna of Andrena was largely revised in the 1970s, but since then, it has received little attention. Molecular investigation of the taxonomically challenging subgenus Taeniandrena has revealed that the situation is more complicated than previously thought with several cryptic and overlooked species. From the species allied to Andrena (T. ) gelriae van der Vecht, 1927, Andrena (T. ) gredana Warncke, 1975 stat. nov. from Spain and Portugal is raised to species status, and Andrena (T. ) levante Wood & Praz sp. nov. from southeastern Spain is newly described. Furthermore, Andrena (T. ) benoisti Wood & Praz sp. nov. is described, having previously been referred to as Andrena (T. ) wilkella beaumonti Benoist, 1961. Andrena (T. ) beaumonti stat. rev. is itself distinct and restricted to the High Atlas Mountains of Morocco. Outside of the subgenus Taeniandrena, Andrena (Euandrena) fortipunctata Wood sp. nov. and Andrena (Charitandrena) hattorfiana nigricauda Wood subsp. nov. are described from Spain, and Andrena (Notandrena) juliana Wood sp. nov. is described from Spain and Portugal. The male of Andrena (Lepidandrena) baetica Wood, 2020 is also described. Andrena (Euandrena) impressa Warncke, 1967 stat. nov. is raised to species status, displaying a West Mediterranean distribution. Finally, a further two species of Andrena are newly recorded for Spain, Andrena laurivora Warncke, 1974 and Andrena confinis Stoeckhert, 1930. Altogether, these findings reinforce the fact that our understanding of the taxonomy and distribution of Andrena in southern Europe remains incomplete.

The Carrizal Formation, exposed in the Marayes-El Carrizal Basin (western Argentina), has been the focus of palaeobotanical studies since the late 1800s. The recent finding of well-preserved palyno­logical assemblages provides the first detailed studies about its palynofloras. In this paper, the 63 taxa identified in the unit are illustrated and discussed, as well as their stratigraphic distribution in equivalent palynological assemblages of Argentina. Some spore species are revised: Uvaesporites hammenii (Herbst) Césari, comb. nov., Retusotriletes wielandii (Jain) Césari, comb. nov. and Lundbladispora stellae (Herbst) Césari, comb. nov. The recognition of Cadargasporites baculatus de Jersey & Paten emend. Reiser & Williams, Craterisporites rotundus de Jersey, Enzonalasporites vigens Leschik, ­Leptolepidites argenteaeformis (Bolkhovitina) Morbey, Protodiploxypinus americus Dunay & Fisher and Rugulatisporites permixtus Playford, among others, appears to be useful for local and intercontinental correlations. A Carnian age is proposed for the palynofloras.

A New Species

This paper certifies the presence of the family Opilioacaridae in the Iberian Peninsula. It is represented by a new species of the Order Opilioacarida, Opilioacarus baeticus, from three localities, plus a photographic record, from southern and southeastern Spain. O. baeticus is described based on adult of both sexes and female tritonymphal instar. A key to genera of the family Opilioacaridae and species of the genus Opilioacarus is given.

abstract The siliciclastic beds outcropping around the village of Kuhlan, northwest Yemen were originally designated the Kohlan Series. Later the sandstone part of the sequence was renamed the Kuhlan Formation by the Yemeni Stratigraphic Commission. The lower part of the Kuhlan Formation (Unit A) yielded diverse and well-preserved palynological assemblages. Their quantitative character and the presence of Anapiculatisporites concinnus, Brevitriletes cornutus, B. parmatus, Deusilities tentus, Dibolisporites disfacies, Microbaculispora tentula, Spelaeotriletes triangulus and Verrucosisporites andersonii, suggests a confident correlation to the 2165A to 2141A biozones of southern Oman, and to Arabian OSPZ2, indicating a Late Carboniferous age for the unit rather than the Late Triassic to Early Jurassic age given on the geological map of western Yemen. The date for the lower Kuhlan Formation indicates that the underlying Akbra Formation, which was previously dated as possibly Early Permian, and Late Carboniferous to Early Permian in age respectively, is probably not younger than the 2165A Biozone and therefore likely to be equivalent to the lower parts of the Al Khlata Formation of Oman.
