The scarce fossil record of stomatopod crustaceans is extended with three new species and two new genera described from the Miocene of California. Squilla laingae new species and Angelosquilla altamirensis new genus and species show clear affinities to the Recent family Squillidae. Topangasquilla gravesi new genus and species can be accommodated within the Recent family Lysiosquillidae. These new species occur in the Monterey and Topanga Formations in Los Angeles County. In addition, three other specimens are described from the Miocene Topanga Formation. The preservation of these stomatopods is among the best noted for any fossils of this group. These specimens show characteristic stages of decay that clearly correspond with those noticed in taphonomic experiments with Recent stomatopods.

New fossils referable to the Cancridae Latreille, 1802 extend the known stratigraphic range of the family into the middle Eocene and the geographic range into South America. Each genus within the family has been reevaluated within the context of the new material. A suite of diagnostic characters for each cancrid genus makes it possible to assign both extant and fossil specimens to genera and the two cancrid subfamilies, the Cancrinae Latreille, 1802, and Lobocarcininae Beurlen, 1930, based solely upon dorsal carapace morphology. Cheliped morphology is useful in assigning genera to the family but is significantly less useful at the subfamily and generic level. Each of the four subgenera sensu Nations (1975), Cancer Linnaeus, 1758, Glebocarcinus Nations, 1975, Metacarcinus A. Milne Edwards, 1862, and Romaleon Gistl, 1848, are elevated to full generic status. Additionally, three new genera and three new species accommodate the new, as well as some previously described taxa, and include Anatolikos new genus, Anisospinos berglundi new genus and species, and Notocarcinus sulcatus new genus and species and several new combinations. Recognition of new genera and reassignment of several species within the Cancrinae indicates that that subfamily may have arisen in the southern hemisphere, contrary to the previous interpretation of the subfamily as a primarily North Pacific or Tethyan group. The Lobocarcininae was primarily a Tethyan group.

Thylacocephalans (Euarthropoda, Thylacocephala) are characterized by their “bivalved” carapace and three anterior prehensile appendages. It is still not clear how they used to live, or what their evolutionary history is. This study focuses on new thylacocephalans from the Late Cretaceous Konservat-Lagerstätten of Lebanon, which yielded the youngest representatives of the group. Three new genera and species are described in the Cenomanian sublithographic limestones of Hakel and Hadjoula, and two new genera and one new species are described in the Santonian chalky limestones of Sahel Alma. Among the specimens from Hakel and Hadjoula, Paradollocaris vannieri, Thylacocaris schrami and Globulacaris garassinoi are the first reports of thylacocephalans in the Cenomanian of Lebanon. Paradollocaris and Thylacocaris are assigned to Dollocarididae based upon their large optic notches limited by rostral and antero-ventral processes, their hypertrophied eyes, and their posterior notches with dorsal and ventral spines. Moreover, Thylacocaris presents a very peculiar character: an optic notch with two strong optic spines protecting the eye. Globulocaris is assigned to Protozoeidae based upon its small carapace with a distinct dorsal notch anterior to a strong postero-dorsal spine. Among the specimens from Sahel Alma, Keelicaris deborae is a new form of thylacocephalans in the Santonian of Lebanon. It presents a very unusual keel-shaped carapace with terraces and punctuations, and is assigned to Microcarididae. The new genus Hamaticaris, presenting a very peculiar hooked rostrum, is also erected for Protozoea damesi Roger, 1946 (Roger J. 1946. Invertébrés des couches à poissons du Crétacé supérieur du Liban. Mémoires de la Société géologique de France (Nouvelle série) 51: 5–92). These two species add to the well-known thylacocephalans from Sahel Alma: Pseuderichtus cretaceus Dames, 1886 (Dames W. 1886. Ueber einige Crustaceen aus den Kreideablagerungen des Libanon. Zeitschrift der Deutschen Geologischen Gesellschaft 38: 551–575), Protozoea hilgendorfi Dames, 1886 and Thylacocephalus cymolopos Lange et al., 2001 (Lange S, Hof CHJ, Schram FR, Steeman FA. 2001. New genus and species from the Cretaceous of Lebanon links the Thylacocephala to the Crustacea. Palaeontology 44 (5): 905–912). The occurrence of such diverse fauna of thylacocephalans markedly increases the diversity of the group during the Late Cretaceous. The diversity and abundance of the Sahel Alma thylacocephalans pose also the problem of causes of their disappearance from the fossil record after the Santonian.

In preparation for upcoming studies, several new taxa of Australian Erotylinae (Coleoptera: Erotylidae) need to be described to make names available. New genera and species in Dacnini and Megalodacnini are described. Echinothallis banderbearella, new genus and species (Dacnini); Microdacne, new genus, with four new species (Dacnini), M. gloriousa, M. lamingtonia, M. nardia, M. styxia; and Episcaphula (Tropidoscaphula) megalodacnoides, new species (Megalodacnini). Variation of female terminalia and other characters in several genera are discussed regarding the monophyly and generic diversity of Dacnini.

Abstract. Three new species and one new genus of adherent foraminiferans have been found within bivalve borings in cobbles from the Faringdon Sponge-gravel (Upper Aptian) of south-central England. The new genus and species, Lapillincola faringdonensis is a uniserial textulariine with an initial planispiral coil and a multiple aperture. Lapillincola gen. nov. is a remarkable homeomorph of Arenonina Barnard, which was originally described as an agglutinated form. Arenonina is shown here to actually be calcareous and perforate, and thus a junior synonym of Rectocibicides Cushman & Ponton. Acruliammina parvispira sp. nov. is another uniserial textulariine with an initial coil. Bullopora ramosa sp. nov. is an adherent polymorphinid with a branching, irregular series of adherent chambers. These foraminiferans may have used the bivalve borings as spatial refuges from the abrasive, high energy environment of the Sponge-gravel.

A New Species

Fourteen new species and six new genera of the molluscan class Monoplacophora are described from the Upper Cambrian Potosi and Eminence formations and the Lower Ordovician Gasconade Formation of the Ozark Uplift of Missouri and some new biostratigraphic horizons are introduced. A new superfamily, the Hypseloconellacea nom. trans. Knight, 1956, and a new family, the Shelbyoceridae, are named. The genus Proplina is represented by five new species: P. inflatus, P. suttoni from the Cambrian Potosi Formation, P. arcua from the Cambrian Eminence Formation and P. meramecensis and P. sibeliusi from the Lower Ordovician Gasconade Formation. A new genus and species in the subfamily Proplininae, Ozarkplina meramecensis, is described from the Upper Cambrian Eminence Formation. Four new monoplacophoran genera in the superfamily Hypseloconellacea and their species are described, including: Cambrioconus expansus, Orthoconus striatus, Cornuella parva from the Eminence Formation, and Gasconadeoconus ponderosa, G. waynesvillensis, G. expansus from the Gasconade Formation. A new genus in the new family Shelbyoceridae, Archeoconus missourensis, is described from the Eminence Formation and a new species of Shelbyoceras, S. bigpineyensis, is described from the Gasconade Formation.

Thirteen new species of sponges are described from coral reefs of the Netherlands Antilles and the Colombian Caribbean. Species were collected during quantitative investigations of reef sponges performed by students of the University of Amsterdam in the period between 1984 and 1991. Most of the reported specimens were taken from undersides of coral rubble, crevices or reef caves (sciophilous habitats) and without exception are small encrusting or fistular sponges. The material reported in this paper includes a new genus and species of Placospongiidae, Placospherastra antillensis n. g. n. sp. , the first Caribbean representatives of the genera Triptolemma (Pachastrellidae) and Megaciella (Acarnidae), viz. Triptolemma endolithicum n. sp. and Megaciella incrustans n. sp., a new species of Timeidae, Timea curacaoensis n. sp., a new species of Microcionidae with peculiar colloscleres, Clathria (Thalysias) collosclera n. sp., two new species of Chondropsidae, viz. Batzella fusca n. sp., and Strongylacidon unguiferum n. sp., three new species of Coelosphaeridae, viz. Forcepia (Forcepia) minima n. sp., Forcepia (Forcepia) fistulosa n. sp., and Forcepia (Leptolabis) microlabis n. sp., a new species of Crellidae, Crella (Grayella) beglingerae n. sp., a new species of Hymedesmiidae, Hymedesmia (Hymedesmia) bonairensis n. sp., and a new species of Mycalidae, Mycale (Paresperella) vitellina n. sp. Most species are represented by only small fragments removed from the substrate by scalpel or diving knife, leaving little and often crumbled preserved type material. This study is intended to demonstrate that the small crusts dominating easily accessible shallow water coral rubble habitats in the Caribbean remain understudied.

Felid Species

ABSTRACTA new genus and species of felid, Ginsburgsmilus napakensis, is described from Napak, Uganda. Material from Songhor, Kenya, previously identified as Afrosmilus turkanae by Schmidt-Kittler (1987) is assigned to this species. A new species of Afrosmilus, A. hispanicus, is described from Artesilla, Spain. These new felid species combine sabre-tooth canines of maochairodont type with cheek teeth similar to those of Pseudailurus. Phylogenetically they are close to Afrosmilus turkanae which shows a greater specialisation towards markedly machairodont forms. On the basis of dental features, we propose a close relationship between these two genera (which we group into the new tribe Afrosmilini) and the tribe Barbourofelini (Sansanosmilus and Barbourofelis), the transition between the two being represented in the fossil record by Prosansanosmilus peregrinus Heizmann et al. 1980.

We describe one new tribe, two new genera and three new species of the subfamily Cypridopsinae Kaufmann, 1900 from Brazilian floodplains. Brasilodopsis gen. nov. belongs in the nominal tribe Cypridopsini, and both new species in this new genus were found in both sexual and asexual populations. Brasilodopsis baiabonita gen. et sp. nov. has a wide distribution and was found in three of the four major Brazilian floodplains. Brasilodopsis amazonica gen. et sp. nov. was recorded only from the Amazon floodplain. Brasilodopsis baiabonita gen. et sp. nov. has a subtriangular shape in lateral view, whereas Brasilodopsis amazonica gen. et sp. nov. is more elongated and has more rounded dorsal margins in both valves, as well as more pronounced external valve ornamentation, consisting of rimmed pores in shallow pits. Paranadopsis reducta gen. et sp. nov. was found in asexual populations in the Upper Paraná River floodplain only and differs from other Cypridopsinae in the more elongated carapace, an A1 with strongly reduced chaetotaxy (hence the specific name) and the total absence of caudal rami in females. Because of these strong reductions in valve and limb morphology, Paranadopsini trib. nov. is created within the Cypridopsinae for this intriguing new genus and species.

Two new genera and three species of the Pantheinae are described. The genus Flavala gen. n. (type-species Acronycta flavala Moore, 1867) is separated from Anacronicta Warren, 1909. The new combination Flavala flavala (Moore, 1867) comb. n. is introduced. Two new species, Flavala crypta sp. n. and F. secunda sp. n. are described based on the result of barcoding of mitochondrial DNA. The new genus Xizanga gen. n. (type-species Xizanga mysterica sp.n.) is tentatively placed in Pantheinae.
