Ants are one of the most successful and widespread organisms in the world. Although ants of the genus Pachycondyla (Hymenoptera: Formicidae: Ponerinae) are predominantly tropical in distribution, Pachycondyla chinensis (Emery) is especially abundant in temperate zones in Asia. Recently, P. chinensis has also become an abundant invasive ant species in the United States. However, it was well-known that the Pachycondyla chinensis species complex remained unresolved. Our molecular and morphological results allow us to distinguish two species in the species complex: the species P. chinensis and the new cryptic species P. nakasujii sp. nov., and these two species are widely and sympatrically distributed and abundant in temperate forests in Japan. Moreover, phylogenetic analysis showed that P. chinensis has been introduced into the United States from Japan. In conclusion, our finding of the new species P. nakasujii suggests that much remains undiscovered even in biologically fascinating and well-studied organisms.

A new species of Triphleps has been received by the Imperial Bureau of Entomology from Mr. E. Ballard, who reports it as attacking the eggs of Heliothis obsoleta, H.S., in Queensland. Although there are already forty-four species of Triphleps described from all parts of the world, this is the first species to be recorded from Australia. Garman & Jewett have previously (1914) reported Triphleps insidiosus, Say, as feeding on the eggs of H. obsoleta, H.S., in the United States.

The genetic characterization of more than 1500 populations belonging to the Daphnia pulex group from the United States and Mexico revealed nine previously unrecognized species. Three of these taxa, showing morphological and genetic affinities, are newly described in this paper and are assigned membership in a new species complex. These species share a unique configuration of P3 sensilla and a triangular ephippial shape which differs from that of other members of the genus Daphnia. All three species are large-bodied forms showing distinctive setulation of the internal margin of the ventral carapace. All these members of the complex appear to be narrow endemics, restricted to temporary ponds in semi-arid areas of the Pacific Northwest.

The crayfish subgenus Procericambarus (genus Orconectes) found in the Eastern Highlands of the United States represents a rich assemblage of stream-dwelling macroinvertebrates. While the taxonomic status and distribution of its members were clarified in a previous study, newly diagnosed characters and newly collected specimens warranted a revision to previous hypotheses of Procericambarus membership in the southeastern United States. Using morphological characters, we describe herein a new species of crayfish occurring in the Tennessee River drainage of northern Alabama and southwestern Tennessee. We also provide a revised key for the identification of members of O. juvenilis Species Complex.

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791
