A new genus and species of basal cyclostome Braconidae is described and figured from a male preserved in mid-Cretaceous amber from northern Myanmar.  <strong><em>Rhetinorhyssalus morticinus</em></strong> Engel, new genus and species, is interesting for its combination of primitive features such as a minute apical costal cell and anal stubs in the forewing, while lacking 2Cu in the hind wing, a putatively derived trait.  As such, the genus may represent a lineage diverging from the braconid stem subsequent to many protorhyssalines, while remaining basal relative to generalized cyclostome groups such as Rhyssalinae.  In addition, the Late Cretaceous <em>Diospilus allani</em> Brues, in Campanian Canadian amber, is transferred to <strong><em>Diorhyssalus</em></strong> Engel, new genus, and its similarity to <em>Rhetinorhyssalus</em> is discussed.  This transfer results in the new combination, <em>Diorhyssalus allani</em> (Brues).  Both genera are tentatively considered as subfamily <em>incertae sedis</em>.

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.

The Family

The family Nomoclastidae is revised and, based on a cladistic analysis, Callcosma Roewer, 1932 is transferred to the family from Cranaidae. The monotypic genus Napostygnus Roewer, 1929, hitherto considered incertae sedis, is also assigned to Nomoclastidae. Zygopachylus Chamberlin, 1925 and Poassa Roewer, 1943 are synonymised under Quindina Roewer, 1914, consequently creating the new combinations Quindina limbata (Roewer, 1914) and Quindina albomarginis (Chamberlin, 1925). The new combination Quindina marginata (Roewer, 1963), comb. nov. is proposed, as the type-species of Deriacrus, D. simoni Roewer, 1932, is not congeneric with Deriacrus marginatus Roewer, 1963 and has the synapomorphies of Quindina, such as a row of large rounded tubercles on the lateral margin and enlarged tubercles on the dorsal scutum. A new genus and species are proposed, Kichua rheimsae, sp. nov., from Ecuador (type locality: Ecuador, Napo, Cantón Quijos, Parroquira Cozanga, Yanayacu Research Station). In addition, seven new species are herein described: Callcosma abrapatricia, sp. nov. (type locality: Peru, Moyobamba, Abra Patricia Private Conservation Area); Callcosma cofan, sp. nov. (type locality: Ecuador, Sucumbíos, Cabanas Cuyabeno); Callcosma barasana, sp. nov. (type locality: Colombia, Vaupés, Tararira, Estacción Biológica da Caparu); Quindina albiocularia, sp. nov. (type locality: Panama, Coclé, Valle de Antón); Quindina burbayar, sp. nov. (type locality: Panama, Reserva Natural Privada Burbayar); Quindina kuna, sp. nov. (type locality: Panama, Darién, Chucantí); and Quindina morae, sp. nov. (type locality: Panama, Gamboa, Sendero del Oleoducto).

A new genus and species of Sisyridae, Stictosisyrapennyi gen. et sp. n., is described from the Late Cretaceous (earliest Cenomanian/late Albian) Myanmar amber. It can be easily distinguished from other sisyrids genera by the configuration of wing venation such as forewing with four ra-rp crossveins, M forked distal to the separation of RP1, CuA pectinate and CuP simple; hind wing 1r-m long and sinuous. Besides, the newly documented spongillaflies bore distinct, irregularly distributed spots on the forewings.

The tribe Melikertini (Apinae: Corbiculata) is an extinct group of highly eusocial bees presently known only from early to late Eocene deposits of Eurasia. Among melikertine diversity are a suite of species peculiar for their rather dramatic morphological specializations, at least in relation to modern corbiculate Apinae. Here we document two new species of Melikertini and utilize standard X-ray as well as propagation phase contrast synchrotron computed microtomography to further explore these and previously known species, revealing finer details not previously observable from melikertines. Accordingly, some species placed in the genera Melikertes Engel and Succinapis Engel are reëvaluated. Three new genera are characterized, as well as some further facial modifications not previously known for the tribe. New taxa and taxonomic changes presented are: Aethemelikertes emunctorii Engel, new genus and species; Haidomelikertes uraeus Engel, new genus and species; H. proboscidea (Engel), new combination; Amelikertotes Engel, new genus; Amelikertotes clypeata (Engel), new combination. Additionally, new records and taxonomic notes on other Baltic amber and Eocene bees are appended, with the following nomenclatural changes established: Palaeomacropis Michez & Nel is recognized as a megachiline rather than a melittid, and is transferred to Megachilinae where it is a new junior synonym of Ctenoplectrella Cockerell (new synonymy); Ctenoplectrella eocenica (Michez & Nel), new combination; a key is provided to species of Ctenoplectrella; Thaumastobombina Engel, new subtribe in Electrapini; Thnetobombus Engel, new subgenus in Protobombus Cockerell; Mesomelissa Engel, new subgenus in Electrapis Cockerell; Electrapis (Euglossopteryx) biesmeijeri (De Meulemeester et al.), new combination.  A list of Eocene bees is appended.

A new genus and species of janiroidean Asellota, Xenosella coxospinosa, is described from the mid-bathyal slope off the coast of south-eastern Australia. Following a comparison of the new species to several families of broadly similar body shape, with emphasis on monotypic Pleurocopidae, a new family, Xenosellidae, is proposed for the new species. In the course of comparing relevant taxa, the current placements of Prethura Kensley in the Santiidae and Salvatiella Müller in the Munnidae are rejected. The two genera are considered to be incertae sedis within the Asellota superfamily Janiroidea pending further studies.

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.

The genus Candobrasilopsis gen. nov. is here described, with C. rochai gen. nov. sp. nov. as type species, from the alluvial valley of the Upper Paraná River. The enigmatic Candonopsis brasiliensis Sars, 1901 is here redescribed and transferred to this new genus, the new combination being Candobrasilopsis brasiliensis (Sars, 1901). The new candonid genus belongs to the tribe Candonopsini, because of the absence of the proximal seta on the caudal ramus. It is closely related to Latinopsis Karanovic & Datry, 2009, because of the relatively short terminal segment of the mandibular palp (length less than 1.5 times the basal width, while this segment is longer than three times the basal width in Candonopsis) and the large and stout b-seta on the T1. However, it differs markedly from Latinopsis in the size and shape of the calcified inner lamellae of both valves and in the type of hemipenis. We also discuss the doubtful allocation of several other genera to the Candonopsini, raise Abcandonopsis Karanovic, 2004 to generic status and reassess the uncertain position of Candonopsis anisitsi Daday, 1905 within Latinopsis.
