A New Species

Purgatorius titusi, represented by 51 teeth and jaw fragments, is described from the lower Paleocene Bear Formation of the Crazy Mountains Basin in south-central Montana. Several synapomorphies, including a weak postprotocingulum and mesial inflection of molar trigonids, are indicative of the taxon's “plesiadapiform” affinities. Other features, such as wider stylar shelf and a less squared lingual outline on upper molars, are more primitive than those of Purgatorius unio, heretofore the earliest occurring species of well-represented primatomorphs.

AbstractThe Careless Creek Quarry (CCQ) is a multitaxic bonebed in the Campanian Judith River Formation of south-central Montana (USA) that produced a diverse assemblage of vertebrates, including several dinosaurian clades. We describe the morphology of the CCQ hadrosaurid material and reevaluate its taxonomic affinities. Our osteological comparative observations, coupled with maximum parsimony phylogenetic analyses, indicate that the majority of the hadrosaurid material is referable to kritosaurin saurolophines. Only an ischium is unambiguously referable to Lambeosaurinae. Most of the kritosaurin specimens likely represent a taxon that forms a polytomy with species of Gryposaurus and Rhinorex condrupus Gates and Sheetz, 2015. This form may represent individuals of either G. latidens Horner, 1992 or G. notabilis Lambe, 1914, or a new species cogeneric or not with Gryposaurus. The juvenile material exemplifies several patterns of mandibular and appendicular osteological variation previously observed in other hadrosaurids. However, it also shows some departures from the common trends, supporting the fact that not all skeletal growth changes can be generalized to all hadrosaurids.

Stratigraphic Range

Mixodectidae (Mammalia, Archonta) are an unusual, poorly known family of dermopteran-like mammals that have been discovered at several North American localities of primarily early Paleocene age. Among the three or four recognized mixodectid genera, Eudaemonema Simpson is perhaps one of the least understood, being known from only a few localities of late Torrejonian and earliest Tiffanian age. This paper reports on a new species of Eudaemonema from the late Paleocene of Alberta, Canada, that significantly extends the geographic and stratigraphic ranges of the genus. Eudaemonema webbi sp. nov. is known from middle and late Tiffanian localities in central and south central Alberta, and it represents the youngest and northernmost species of Eudaemonema so far discovered. E. webbi differs from the genotypic species E. cuspidata in being larger and in having a suite of dental characters (e.g., molariform posterior premolars, enlarged molar protocone and hypocone, development of a second grinding platform on the lower molars) that suggests an increased emphasis on grinding during mastication. E. webbi possesses several dental features (e.g., broad, shelf-like molar paraconid–paracristid, lingually shifted molar hypoconulid) that resemble those of cynocephalids (Mammalia, Dermoptera), with these resemblances interpreted herein as convergent. The occurrence of E. webbi at Gao Mine extends the stratigraphic range of Eudaemonema into the late Tiffanian (Ti5) and represents the youngest known record of Mixodectidae.

A New Species

Pycreus rubidomontanus is described as a new species. It is relatively widespread in tropical West Africa where it had been confused up to present with P. atrorubidus, a very rare endemic species from Zambia in south-central Africa that probably is known only from the type gathering. Differences between these and other similar species are discussed and the new species is copiously illustrated.

A New Species

A new species of the genus Colias Fabricius from the Arequipa region of Peru, C. misti Kir’yanov sp. nov., stat. nov., is established by raising it from the subspecies rank, C. lesbia misti Kir’yanov 2017. This taxonomic act is justified after detailed comparison of C. misti with representatives of phenotypically similar other South American Colias, including the subspecies of C. lesbia. The newly presented taxa are diagnosed by adult morphology, bionomics, and male genitalia. The diagnosis of a new subspecies Colias misti ccota Kir’yanov ssp. nov., discovered in the World’s deepest canyon Cotahuasi (Peru), is based on different and stable characters in phenotypes, genitalia, and bionomics of C. misti ccota and C. misti misti. Both subspecies of C. misti are endemic to the Western slopes of the Andes. It is also demonstrated that the shape of the male aedeagus is diagnostic for a reliable identification of the South American Colias.

Additional specimens of three newly described Chilean species of Trophon s.l. Monfort, 1810 have been dredged recently off south-central Chile, and we here list the new data and illustrate the radulae. Another species, Trophon wilhelmensis Ramírez-Bohme, 1981, is combined with Coronium Simone, 1996. Pagodula concepcionensis n. sp. is described and another species remains unidentified. A type species is designated for Pagodula Monterosato, 1884. Part of the new material comes from an area of methane seepage located northwest of the Bay of Concepción, from 726 to 930 m depth. Many drilled valves of two species of chemosymbiotic clams (Calyptogena gallardoi Sellanes & Krylova, 2005 and Thyasira methanophila Oliver & Sellanes, 2005) were also obtained at the seep site. We assume that this holes document attacks of this trophonines to the clams.

The genus Microlithosia Daniel, 1954 is a member of the subtribe Lithosiina, tribe Lithosiini of the subfamily Arctiinae and family Erebidae. It was described as a monotypic genus for its type species, M. shaowuica Daniel, 1954 from SE China (Fujian, Shaowu).Recently, the genus was reviewed by Dubatolov & Kishida (2012) with the inclusion of four species: M. shaowuica Daniel,1954 (from its type locality, and additionally from South Central China (Hunan)), M. nanlingica Dubatolov, Kishida & Wang, 2012 from South-East China (Guangdong), M. umbripuncta (de Joannis 1928) from North Vietnam and Thailand (Chiang Mai, Chanthaburi, Nakhon Nayok, Nakhon Ratchasima, Kanchanaburi, Chumphon, Phitsanulok), and M. decreta (Butler 1877) from Borneo and Thailand (Nakhon Ratchasima). Later on, Bucsek (2012, 2014) described two new species, M. pseudodecreta Bucsek, 2012 and M. johara Bucsek, 2014 both from Peninsular Malaysia. Kirti and Singh (2016) subsequently added a further species, M. champhaiensis Singh & Kirti, from India (Mizoram, Champhai). So at present, Microlithosia comprises seven species, with single from India.
