Abstract. Mennerotodus Zhelezko, 1994, is an extinct lamniform shark known to occur in Paleogene strata of the Tethyan region of Asia and Europe. Although only a single species has been named, multiple subspecies have been erected and used as biostratigraphic tools in Asia. The genus has not been reported with confidence outside of the Tethyan region, but we have identified two new species of Mennerotodus from Paleogene deposits of the southeastern United States. Mennerotodus mackayi sp. nov. is described by teeth occurring in the lower Paleocene (Danian Stage) Pine Barren Member of the Clayton Formation of southern Alabama. A middle Eocene (Bartonian) species, Mennerotodus parmleyi sp. nov., is based on material occurring in the Clinchfield Formation in central Georgia. The early Paleocene record could indicate a North American origin for Mennerotodus relatively soon after the K–Pg event, with subsequent radiation to other parts of the world. The genus is likely more widely distributed than is currently known, but teeth can easily be overlooked due to their similarity to other taxa.

Worker Caste

In ants, social parasitism is an umbrella term describing a variety of life-history strategies, where a parasitic species depends entirely on a free-living species, for part of or its entire life-cycle, for either colony founding, survival, and/or reproduction. The highly specialized inquiline social parasites are fully dependent on their hosts for their entire lifecycles. Most inquiline species are tolerant of the host queen in the parasitized colony, forgo producing a worker caste, and invest solely in the production of sexual offspring. In general, inquilines are rare, and their geographic distribution is limited, making it difficult to study them. Inquiline populations appear to be small, cryptic, and they are perhaps ephemeral. Thus, information about their natural history is often fragmentary or non-existent but is necessary for understanding the socially parasitic life history syndrome in more detail. Here, we describe two new species of inquiline social parasites, Nylanderia deyrupisp. nov. and Nylanderia parasiticasp. nov., from the southeastern United States, parasitizing Nylanderia wojciki and Nylanderia faisonensis, respectively. The formicine genus Nylanderia is large and globally distributed, but until the recent description of Nylanderia deceptrix, social parasites were unknown from this genus. In addition to describing the new social parasite species, we summarize the fragmentary information known about their biology, present a key to both the queens and the males of the Nylanderia social parasites, and discuss the morphology of the social parasites in the context of the inquiline syndrome.

Two New Species

Recent surveys to document the poorly known moth fauna of the Bahamas have resulted in the collection of more than 60 morphospecies of Tortricidae. Among these are several Eucosmini, including undescribed representatives of Eucosma and Pelochrista that are similar to several species present in the southeastern United States. Eucosma bahamae, sp.n., a member of the E. refusana group, and Pelochrista wrighti, sp.n., a member of the P. canana group, are described and illustrated.

The moth-fly genus Eurygarka Quate (Diptera: Psychodidae) is revised to include three species. Two new species: E. cyphostylus, n. sp. and E. nelderi, n. sp. from the southeastern United States are described. The adult male and female of E. helicis (Dyar) are redescribed. A key to adult males of the three known species of Eurygarka is provided. The generic placement of Eurygarka is discussed.

AbstractTwenty-one species of echinoid are reported from Paleocene rocks of the eastern United States along the outcrop belt from Texas to New Jersey. Six of these are strictly early Paleocene age (Danian), nine strictly late Paleocene age (Thanetian), five range throughout the Paleocene, and one previously reported Paleocene species (Diplodetus moscovensis) is most likely a Cretaceous species. Two new species are described, Salenia palmyra n. sp., from the Danian Clayton Formation in Alabama and Georgia, and Ova rancoca n. sp., from the Thanetian Vincentown Formation in New Jersey. One new species from the Clayton Formation in Mississippi, Arbaciella? sp., is left in open nomenclature.
