The genus Ahermodontus Báguena, 1930 (Coleoptera: Scarabaeidae: Aphodiinae) is currently comprised of three species: A. marini Báguena, 1930 and A. ambrosi (Pardo Alcaide, 1936) from southern Spain and Morocco and A. bischoffi (Všetečka, 1939) from Albania (see e.g., Dellacasa et al. 2001, 2002, 2016). The distribution and bionomy of both of the western Mediterranean Ahermodontus species are relatively well known. Contrastingly, A. bischoffi was described using a single female specimen collected by A. Bischoff in Llogara, Albania in 1934 (Všetečka 1939) and additional specimens remained unknown until now. Geodesist Alfons Bischoff (1890–1942) was a famous Albanian speleologist and insect collector (Horn et al. 1990; Genest & Juberthie 1994; Zhalov 2015). He often made his insect material accessible to specialists on particular insect groups and several species is dedicated to him: for example, the Carabidae (Coleoptera) species Duvalius bischoffi Meschnigg, 1936, Pterostichus bischoffianus Jedlička, 1936, and Zabrus bischoffi Müller, 1936, and the paper wasp Polistes bischoffi Weyrauch, 1937 (Hymenoptera: Vespidae).

Based on morphological and molecular studies of material from caves in three karst regions of Crimea, the small, apparently relictual, Euro-Mediterranean and Macaronesian false scorpion genus Pseudoblothrus Beier, 1931 is shown to contain only one troglobiont species there, P. roszkovskii (Redikorzev, 1918), of which P. ljovuschkini Krumpál, 1984 and Obisium tauricum Lebedev, 1927 are junior subjective synonyms. A detailed redescription of the adults and tritonymph of P. roszkovskii is provided, together with phylogenetic and zoogeographical analyses.

Species in the genus Ameles Burmeister and Pseudoyersinia Kirby (Amelini) are traditionally defined as small-sized, ground-dwelling mantids whose males are distinct for being, respectively, macropterous and brachypterous. However, comparative morphological studies across Amelini confirmed the existence of short-winged males in Ameles, suggesting that this traditional diagnostic concept does not apply to all species. Our analyses of several species from West Mediterranean localities (Canary Islands, Spain, Italy, and Morocco) resulted in the relocation of Pseudoyersinia andreae Galvagni, 1976 to Ameles asAmeles andreae (Galvagni, 1976) (n. comb.) with Ameles insularis Agabiti, Ippolito & Lombardo, 2010 as its new synonym (n. syn.), the clarification of the taxonomic identity of A. gracilis (Brullé, 1838) and A. maroccana Uvarov, 1931, including diagnoses of their males, and the description of Ameles spallanzania obscura (n. ssp.) (from Spain). We also take the opportunity to describe Pseudoyersinia maroccana (n. sp.) (from Morocco) based on museum specimens separating it from Ameles maroccana Uvarov, 1931. We also found that wing length is positively correlated to ocelli size. We discuss this trend from an ecological, evolutionary, and biogeographic perspectives to both facilitate species circumscription and justify the taxonomic modifications herein introduced.

The sauropod of El Oterillo II is a specimen that was excavated from the Castrillo de la Reina Formation (Burgos, Spain), late Barremian–early Aptian, in the 2000s but initially remained undescribed. A tooth and elements of the axial skeleton, and the scapular and pelvic girdle, represent it. It is one of the most complete titanosauriform sauropods from the Early Cretaceous of Europe and presents an opportunity to deepen our understanding of the radiation of this clade in the Early Cretaceous and study the paleobiogeographical relationships of Iberia with Gondwana and with other parts of Laurasia. The late Barremian–early Aptian is the time interval in the Cretaceous with the greatest diversity of sauropod taxa described in Iberia: two titanosauriforms, Tastavinsaurus and Europatitan; and a rebbachisaurid, Demandasaurus. The new sauropod Europatitan eastwoodi n. gen. n. sp. presents a series of autapomorphic characters in the presacral vertebrae and scapula that distinguish it from the other sauropods of the Early Cretaceous of Iberia. Our phylogenetic study locates Europatitan as the basalmost member of the Somphospondyli, clearly differentiated from other clades such as Brachiosauridae and Titanosauria, and distantly related to the contemporaneous Tastavinsaurus. Europatitan could be a representative of a Eurogondwanan fauna like Demandasaurus, the other sauropod described from the Castrillo de la Reina Formation. The presence of a sauropod fauna with marked Gondwananan affinities in the Aptian of Iberia reinforces the idea of faunal exchanges between this continental masses during the Early Cretaceous. Further specimens and more detailed analysis are needed to elucidate if this Aptian fauna is caused by the presence of previously unnoticed Aptian land bridges, or it represents a relict fauna from an earlier dispersal event.

A bizarre latimeriid coelacanth fish from the Middle Triassic of Switzerland shows skeletal features deviating from the uniform anatomy of coelacanths. The new form is closely related to a modern-looking coelacanth found in the same locality and differences between both are attributed to heterochronic evolution. Most of the modified osteological structures in the new coelacanth have their developmental origin in the skull/trunk interface region in the embryo. Change in the expression of developmental patterning genes, specifically the Pax1/9 genes, may explain a rapid evolution at the origin of the new coelacanth. This species broadens the morphological disparity range within the lineage of these ‘living fossils’ and exemplifies a case of rapid heterochronic evolution likely trigged by minor changes in gene expression.

This paper describes and illustrates a new genus and a new species belonging to the family Nesticidae based on morphology and supported by molecular data. The new genus, Kryptonesticus gen. nov., groups eight species spread from Bulgaria and Turkey to Croatia, including Montenegro, Bosnia and Herzegovina and Crete. As a result, seven new combinations are proposed: K. eremita (Simon, 1879)comb. nov., K. arenstorffi(Kulczyński, 1914) comb. nov., K. fagei(Kratochvíl, 1933) comb. nov., K. beroni(Deltshev, 1977) comb. nov., K. beshkovi(Deltshev, 1979) comb. nov., K. henderickxi(Bosselaers, 1998) comb. nov. and K. dimensis (López-Pancorbo, Kunt & Ribera, 2013) comb. nov., all ex Nesticus. Kryptonesticus deelemanae gen. et sp. nov. is described on the basis of both sexes and its phylogenetic relationships with closely related species are discussed based on morphological and molecular data (the cox1, rrn and H3 genes). In addition, the species of this new genus (except for K. eremita) are clear candidates for protection: they have highly restricted ranges and some of them show a high degree of adaptation to the subterranean environment.

Kryptonesticus gen. nov.
Type species
Kryptonesticus deelemanae gen. et sp. nov.
Etymology: The prefix “Krypto”, from Ancient Greek κρυπτός (kruptós “hidden”), alludes to the long time it took to diagnose this evolutionary line.
Distribution:From Bulgaria and Turkey to Croatia, including Montenegro, Bosnia and Herzegovina and Crete. All these species are known only from the type locality, or have small distribution ranges. K. eremita is an exception; this species is linked to human activities and can be found in hangars, cellars and cottages. It has been cited from France and Italy to Bulgaria and Turkey. It is a potentially invasive species, found in an abandoned air-raid tunnel in Auckland, New Zealand (Vink & Dupérré 2011).
Krypyonesticus deelemanae gen. et sp. nov.
Etymology: The specific name is a patronym in honor of Christa Laetitia Deeleman-Reinhold, an important Dutch arachnologist and a dear friend. Her work has vastly raised the knowledge of the cave spider fauna of Dinarides. The species name is in possessive genitive.
Distribution: The new species is endemic to Croatia; it is distributed on Biokovo Mt in central Dalmatia, a coastal region in Croatia. So far it has been recorded in 20 caves scattered through the whole mountain, from the south-west sea side to the north-east continental side, from the 310 to 1640 asl (Fig. 6A). Data on all records of K. deelemanae gen. et sp. nov. are given in Appendix 2. The distribution area of K. deelemanae gen. et sp. nov. is more than 80 km away from that of K. fagei and more than 100 km from that of K. arenstorffi (Fig. 6B).
Natural history: The type locality, Samogorska špilja, is a small cave with two entrances (Fig. 7). On the date of the last collection, 23 Jan. 2016, the air temperature in the cave was 0.5°C with cold air streaming through the cave, mostly near the cave floor. Spiders were found freely walking on the ceiling of the chamber (probably avoiding the cold air flow at the bottom) and on the side walls of the cave. The temperature in other caves where K. deelemanae gen. et sp. nov. is found ranges from 0 to 15°C. Some of those caves are very small and are greatly influenced by outside conditions (like the type locality), while the others are quite big, have a true cave microclimate and harbor diverse types of cave habitats (for example Pretnerova jama, a 254-meter deep pit). No other nesticid species are found in caves on Biokovo Mt.

Marked is the town of Trebinje, near the type locality for K. arenstorffi, and also the towns of Mostar and Jablanica, between which is Čudna jama, a dubious record for K. arenstorffi. Also marked is Cetinjska pećina, the southernmost locality for K. arenstorffi.

Abstract Rhabdodontidae is a successful clade of ornithopod dinosaurs, characteristic of Late Cretaceous continental faunas in Europe. A new rhabdodontid from the late Campanian, of southern France, Matheronodon provincialis gen. et sp. nov., is characterized by the extreme enlargement of both its maxillary and dentary teeth, correlated to a drastic reduction in the number of maxillary teeth (4 per generation in MMS/VBN-02-102). The interalveolar septa on the maxilla are alternately present or resorbed ventrally so as to be able to lodge such enlarged teeth. The rhabdodontid dentition and masticatory apparatus were adapted for producing a strict and powerful shearing action, resembling a pair of scissors. With their relatively simple dentition, contrasting with the sophisticated dental batteries in contemporary hadrosaurids, Matheronodon and other rhabdodontids are tentatively interpreted as specialized consumers of tough plant parts rich in sclerenchyma fibers, such as Sabalites and Pandanites.

Matheronodon provincialis gen. et sp. nov.
Etymology. Matheron: in honor of Philippe Matheron, who was the first to describe dinosaur remains in Provence; odous (Greek): tooth; provincialis (Latin): from Provence (southern France).
Holotype. MMS/VBN-02-102, a right maxilla; housed in the collections of the Musée du Moulin seigneurial (MMS, Velaux, France).
Horizon and locality. ‘Begudian’ (local stage) sandstones, late Campanian, Late Cretaceous6,8. Velaux-La Bastide Neuve, Aix-en-Provence Basin, Bouches-du-Rhône, southern France.
Diagnosis. Rhabdodontid ornithopod characterized by the following autapomorphies: enlargement of both maxillary and dentary teeth (up to 5 cm in mesio-distal length); reduction of maxillary tooth families (4 per generation in MMS/VBN-02-102); interalveolar septa on the maxilla alternately present or resorbed ventrally, so that one functional tooth is lodged in two paired alveoli; shortened rostral process on the maxilla; broad dorsal shelf along the rostral third of the maxilla; more than 25 vertical and parallel ridges on the labial side of the maxillary teeth.
