Freshwater Environments

Two neogastropod species occur in brackish intervals in the Pebas Formation (late Middle to early Late Miocene) of Peru and Colombia in western Amazonia. Purpura woodwardi Roxo, 1924, is assigned to Melongena Schumacher, 1817 (Melongenidae), and ?Nassarius reductus (Nassariidae) is recognized as a new species. These gastropods are among the very few marine invaders in the otherwise freshwater Pebas fauna. The small number of marine to freshwater transitions among South American molluscs contrasts with the situation among South American fishes and southeast Asian molluscs. It may be related to seasonal fluctuations in water level and anoxia in present-day South American freshwater environments, as well as to predation and productivity.

A New Species

A new species of the termite genus <em>Gyatermes</em> Engel &amp; Gross (Archotermopsidae) is described and figured from a beautifully preserved forewing in late Neogene sediments of Nagano Prefecture, central Japan.  The approximately 27-mm long forewing of <em><strong>Gyatermes naganoensis</strong></em> Engel &amp; Tanaka, new species, is preserved in Late Miocene (late Messinian) mudstone of the Ogawa Formation (<em>ca</em>. 6 Ma), and is distinguished from its slightly older and larger congener <em>G. styriensis</em> Engel &amp; Gross, from the early Tortonian of Styria, Austria.  Comments are provided regarding the paleoclimatic implications of a giant termite in the Miocene fauna of Nagano.

A New Species

A new tribe of the Conocephalinae, Armadillagraeciini Rentz, Su, Ueshima is described to include three known Australiangenera: Armadillagraecia, Kapalgagraecia and Lichenagraecia gen. nov. Lichenagraecia gen. nov. is the eastern repre-sentative of the tribe, the others from the Northern Territory, northern Western Australia and western Queensland. Threenew genera in the tribe Agraeciini are described from the rainforests of north-eastern Queensland, Australia. Ingrischa-graecia gen. nov. is known from a single species, I. iterika sp. nov. Emeraldagraecia gen. nov. is known from two spe-cies, E. munggarifrons and E. windsorana spp. nov. Miniagraecia gen. nov. is described from two species: M. milyali andM. goorijupa spp. nov. In the Listroscelidinae; Requenini, a new species of the previously monotypic genus Xingbaoia,X. irvineorum sp. nov. is described from two localities in peril from repeated prescribed burning. Distribution maps, keys, measurements, song patterns and cytological observations are provided for most species.

A New Species

A new species of the Pliocene–Pleistocene flat-headed peccary, Platygonus pollenae, has been recovered latest Hemphillian (latest Miocene) localities from Nebraska, Kansas, Colorado, and Texas. It can be distinguished from other tayassuids by its distally rounded wing-like zygomatic process, and its subzygodont cheek teeth. In contrast to more derived species of Platygonus, it is much smaller in size, its molars are relatively more bunodont, the talon and talonid cusps are retained on the premolars of most individuals, and the mandibular symphysis lacks a median keel on the chin. In these characters, it is the earliest and the most primitive species of Platygonus known. It is more primitive than the typical Blancan species, or any of the species from the Pleistocene, and demonstrates the origin of this important Pleistocene mammal in the latest Miocene.
