Abstract Stenamara mia is a new genus and species of a rare pycnodontiform fish from the Barremian, early Cretaceous, lacustrine beds of Las Hoyas, province of Cuenca, Spain. It was previously considered Eomesodon sp., but a number of characters clearly separates it from the genus Eomesodon: lack of prognathism; absence of nuchal plates; presence of a parietal process and of only two rows of teeth in the prearticular; and peltate pattern of ossification and distribution of scales, that is, scales are present only before the level of the unpaired fins, and are complete only in the ventralmost abdominal area. The unique combination of these and other characters, plus the following autopomorphies, diagnoses the new taxon: presence of a strongly curved dorsal prominence that results in an ovoid shape of the contour of the body; body deeper than long, with maximum body height near 125% of standard length; and narrow, high cloaca formed by only two differentiated scales, the posterior one considerably longer than the anterior one. Stenamara mia nov. gen. nov. sp. is considered a primitive Pycnodontidae, pending a cladistic analysis to determine precisely its phylogenetic relationships.

Melaniphax suffusculus gen. et sp. nov. is described from Costa Rica, representing the 57th delphacid species recorded from the country to date. The new genus is superficially similar to Caenodelphax Fennah in general appearance in that the body is uniformly colored with the wings infuscated. Distinctive features of the new taxon include simple, forceps-like gonostyli, a broadly compressed aedeagus with large serrate lateral flanges, and the anal tube bearing a pair of short, stout, truncate, caudally-directed processes on the ventro-caudal margin and slender, elongate processes from the antero-ventral margin.

Aenigmachanna gollum, new genus and species, is described from Kerala, South India. It is the first subterranean species of the family Channidae. It has numerous derived and unique characters, separating it from both the Asian Channa Scopoli and the African Parachanna Teugels & Daget. Uniquely among channids, A. gollum has a very slender (maximum body depth only 11.1–11.3% SL), eel-like body (head length 20.8–21.6% SL), large mouth (jaw length 60.4–61.1 % HL), 43–44 anal-fin rays, 83–85 scales in a lateral series, an unusual colour pattern and it lacks pored lateral-line scales on the body and body buoyancy. In addition, it is distinguished by its DNA barcode sequence, which is 15.8–24.2% divergent from other species of the family Channidae. Morphological modifications usually associated with a subterranean life, such as reduction of eyes and enhancement of non-visual senses (taste, smell, mechanosensory systems) are absent in A. gollum. However, it shares with subterranean fishes a slight reduction of its pigmentation in comparison to epigean channids.

Only one species of Tanaidacea, Expina typica, has been hitherto reported as an endosymbiont; it was recovered from the body cavity of deep-sea holothurians. During a survey of the deepsea benthic community in the Florida Straits off the Bahamas, Terebellatanais floridanus, a new genus and species of a tanaidomorphan tanaidacean was recovered at a depth of 545 m from the oral cavity of the terebellid polychaete Biremis blandi. Terebellatanais gen. nov. is tentatively assigned to the family Mirandotanaidae, as it appears to have affinities with Mirandotanais and Pooreotanais but also with Expina. It is distinguished from these genera by a unique combination of characters, including four antennular and antennal articles, a naked endite of the maxillipedal basis, hook-like chelipeds, the armature of the pereopods, and characters of the mouthparts. Most of the specimens of T. floridanus examined are mancas, but some were distinctly larger and with a different development of the last pereopod, thus suggesting that at least two manca stages are represented. The occurrence of the new genus and species within the oral cavity of B. blandi, its peculiar morphology, and the absence of fully grown adults, suggest that T. floridanus may be a symbiont of Biremis blandi at least during part of its development. Whether this relationship is commensal or parasitic remains to be determined.

New Synonymy

A new genus of Entiminae, an endogean weevil of the tribe Otiorhynchini, Giavarhynchus Bellò, Osella & Ruzzier, gen. n., and its type species Giavarhynchus amicorum Bellò, Osella & Ruzzier, sp. n. are described. The new taxon is readily distinguished from all other members of the tribe due to the unique combination of lack of eyes, elongate rostrum with a ventral transverse furrow and excised lateral margins located at apical third, punctation of pronotum of two distinct sizes arranged in a distinctive pattern, interval 7 of elytra protruding from base of pronotum and crenulate basally, metafemora bearing a spine-like tooth much larger than that of pro- and mesofemora, female tibiae granulate on inner margin, bisinuous mesotibiae. The following synonymy is proposed: Nematocerus Reiche, 1849 (= Cyrtozemia Pascoe, 1872, syn. n.; = Holcorhinosoma Voss, 1939, syn. n.). New combinations are: Nematocerus cognatus (Marshall, 1916), comb. n.; Nematocerus dispar (Pascoe, 1872), comb. n.; Nematocerus pilipes (Morimoto, 2015), comb. n., all from Cyrtozemia; Nematocerus subtuberculatus (Voss, 1939), comb. n. from Holcorhinosoma. New tribal placement is: Pseudocratopus Hustache, 1921 from Otiorhynchini to Peritelini. New subgeneric placement is that of Otiorhynchus deceptorius Białooki, Germann & Pelletier, 2017 and of Otiorhynchus incisirostris Białooki, Germann & Pelletier, 2017 from Otiorhynchus (Lixorrhynchus) Reitter, 1914 to Otiorhynchus (Aranihus) Reitter, 1912.

The fossil fauna of turtles from the Santana Formation, Araripe Basin, Early Cretaceous from Northeastern Brazil, includes, to exception of the Santanachelys gaffneyi (Cryptodira, Protostegidae), only pelurodiran taxa. A new genus and species, Caririemys violetae gen. et sp. nov. (Pleurodira, Pelomedusoides), from the Romualdo Member, upper section of the Santana Formation, is described here. Caririemys is based on one specimen consisting of a carapace, several vertebrae, a right femur and a right pelvis. Caririemys differs of the other pleurodirans from the Santana Formation by the following combination of characters: oval and moderately domed carapace; complete neural series reaching the suprapygal; and neural plate 8 shows an extensive contact with costal 7 and 8. This new taxon enhances the turtle diversity of the Santana Formation, which is presently the most diverse deposit of Mesozoic Testudines in the country.

A new characiform is herein described from the Eocene-Oligocene sediments exposed in the Aiuruoca basin, in southern Minas Gerais State, Brazil. Recently, two other characid species were described for this same fossil level: †Paleotetra aiuruoca and †Paleotetra entrecorregos. The holotype of this new characiform is represented by an articulated specimen preserved as part and counterpart, in which the most anterior part of the head is missing, including the jaws. Despite the lack of the diagnostic characters from the snout, a unique combination of characters allows its differentiation from other Neotropical characiforms, raising a new genus and species: †Bryconetes enigmaticus. Among these characters are: the presence of a supraorbital, dentary with inflated pentacuspidate teeth arranged in a single row, infraorbital 3 expanded and ornamented with punctuations and grooves, a large anal fin with iii+22-23 rays, and the caudal fin with 11 ventral procurrent rays of which the anteriormost are fused in laminar bones. A phylogenetic analysis using morphological data was performed and recovered †Bryconetes enigmaticus as a stem group to characiforms lacking a supraorbital. Based on the results of this analysis, a discussion of the potential relationships of the new taxon with other characiforms is presented.

The new genus and its type species Armasius iberianus, a remarkable cladonotine tetrigid, are described based on a single individual collected from Monte Iberia, Guantánamo Province, in eastern Cuba. Armasius is characterized for having a large pronotum flattened on top to a thin crest that is uniformly elevated only about half the body height, the pronotum covers the whole abdomen, narrowing posteriorly, and turning upwards at its posterior end. A character not yet seen in any other Antillean Cladonotinae is that the posterior angles of the lateral lobes of the pronotum project laterally, flattening to form a horizontal triangular spine.
