I describe a new species of blindsnake of the genus Ramphotyphlops Fitzinger, 1843, from Woodlark Island, off the southeastern tip of New Guinea. The new species is a member of the R. flaviventer (Peters, 1864) group and is characterized by a unique combination of number of longitudinal scale rows, details of the shape of the rostral scale, color pattern, and shape of the tail spine. The nearest related species (R. depressus Peters, 1880) in this group occurs 380 km to the northeast from the new species, and the remaining species of the group lie no closer than 2570 km distant. The new species seems most similar morphologically to relatives from far western New Guinea, but this could be due to homoplasy or plesiomorphy. The species seems common in the widespread mature secondary forest that occurs across the island, but non-traditional land tenure and repeated outside proposals to deforest much of the island pose a continuing series of threats to this and other endemic species on Woodlark.

A new species of New Guinea Worm-Eating Snake (Serpentes, Elapidae, Toxicocalamus Boulenger, 1896) from Western Highlands Province, Papua New Guinea
We describe a new species of New Guinea Worm-Eating Snake (Elapidae: Toxicocalamus ) from a specimen in the reptile collection of the Papua New Guinea National Museum and Art Gallery. Toxicocalamus longhagen sp. nov. can be easily distinguished from other species of this genus by the presence of paired subcaudals, a preocular scale unfused from the prefrontal scale, a prefrontal distinct from the internasal scale that contacts the supralabials, a single large posterior temporal and two postocular scales. The new taxon is currently known only from one specimen, which was collected from Mt. Hagen Town in Western Highlands Province, Papua New Guinea in 1967. The new species was originally identified as T. loriae , but the unique head scalation and postfrontal bone morphology revealed through micro-computed tomography scanning easily distinguish the new species from T. loriae sensu stricto . This is the first species of this genus described from Western Highlands Province.

A new species of Cyne (Loranthaceae) from Bucas Grande and Dinagat Islands, Philippines is described and named C. barcelonae in honor of the Filipina botanist Julie F. Barcelona. Phylogenetic analysis using the complete nuclear ribosomal DNA cistron confirms it is sister to C. banahaensis, the only species among the six in the genus with complete descriptions of floral morphology. The species is similar to the rare C. perfoliata of Papua New Guinea by having connate-perfoliate upper leaves but differs from others in the genus by possessing palmate leaf venation, inflorescences lacking an operculum, light green corollas, and stamens with filaments. No type material for Cyne quadriangula exists, thus this taxon is only known from the original protologue. It was rediscovered on Bucas Grande Island and that collection was described and used as the neotype for the species. A revised description of the genus and key to the seven species is provided.more » « less

null (Ed.)Abstract Institutions to regulate marriage and sexual mores are nearly universal across human societies to assure production and reproduction and weave the fabric of society. The stakeholders are many. What happens when marital traditions break down in times of rapid change? Taking a long-term perspective, we will first look at developments in marital institutions that occurred after the arrival of the sweet potato (ca. 400 BP) among the Enga of Papua New Guinea. Next, we will document changes in recent marital practices of 402 Enga women collected in 2007. With data from 270 public forums in customary courts applying restorative justice between 2008 and 2019, we will consider (a) the impact of the breakdown of marital institutions and (b) responses to adapt norms to new practices. In the absence of regulation by ‘traditional’ institutions, individuals pursue their own interests and passions with negative outcomes for families and communities. Communities, non-governmental organisations, churches and government throughout Papua New Guinea are seeking to adapt norms to new conditions. We consider both norm change resulting from community action via customary courts and what communities strive to preserve. Cultural institutions and accompanying norms are important factors in assuring production and reproduction; however, they can instill attitudes that inhibit adaptation.more » « less

Melanesian blindsnakes of the genus Gerrhopilus have been little collected or researched. I examined specimens assigned in museums to Gerrhopilus inornatus and found considerable morphological diversity among them that indicates the presence of multiple species. I redescribe G. inornatus (Boulenger) based on the holotype and one additional specimen, and I describe six new species among specimens currently subsumed under that name from Papua New Guinea: Gerrhopilus flavinotatus sp. nov., Gerrhopilus lorealis sp. nov., Gerrhopilus papuanorum sp. nov., Gerrhopilus polyadenus sp. nov., Gerrhopilus slapcinskyi sp. nov., and Gerrhopilus wallachi sp. nov. Each species is currently known from only 1–3 specimens, and all but two are known only from single localities. In addition to traditional information on scale counts, habitus, and color patterns, I found the numbers and distributions of epidermal glands among the head shields to be especially useful for discriminating among species. The number of recognized Melanesian Gerrhopilus has increased tremendously in recent years, but the region has been poorly sampled for these snakes, and it is to be expected that additional species will be identified at such time as surveys can more effectively target these cryptic snakes.more » « less

Abstract New Guinea and surrounding islands are home to some of the richest assemblages of insular biodiversity in the world. The key geological drivers of species richness in this region are largely considered to be mountain uplift and development of offshore archipelagos—some of which have accreted onto New Guinea—with the role of mountain uplift and elevational gradients receiving more attention than the role of isolation on islands. Here, we examine the distribution of lineage richness and body-size diversity in a radiation of Melanesian lizards that is almost entirely absent from montane habitats but closely associated with islands—the geckos of the genusNactus. Our data indicate that eastern New Guinea—centred on the East Papuan Composite Terrane (EPCT)—shows particularly high levels of endemism and body-size diversity and is also inferred to be a source area for multiple independent colonisations elsewhere in New Guinea, the Pacific and Australia. TwoNactuslineages in Australia have closest relatives occurring to the north of New Guinea’s Central Cordillera, suggesting dispersal through this area in the mid-Miocene, possibly via seaways that would have isolated the islands to the east and west of the proto-Papuan region. Syntopic species tend to differ in body length; however, at a phylogenetic scale, this trait appears to be conservative, with small-sized and large-sized species clustered into separate lineages. These data suggest that species richness in MelanesianNactusis in part explained by morphological diversification enabling the presence of sympatric communities to exist, but to a greater extent by multiple instances of dispersal and extensive allopatric and parapatric speciation, especially in and around the islands of the EPCT.more » « less
