This paper highlights the most unique characteristics of Araceae: their high species diversity, high habit diversity, high rates of endemism, and high rates of new species discovery. Also discussed is the origin of the family in the Early Cretaceous period and its modern-day worldwide distribution, which shows high generic diversity in Asia and high species diversity in South America. The last 40 years have shown dramatic increases in the number of species known for most of the Neotropical genera but with most of the growth coming from Central America. The development of computerized determination keys has led to the realization that many more species are likely to be new to science. This study also recommends future directions and localities or regions where most aroid research should be concentrated.

Abstract Burmese amber continues to provide unique insights into the terrestrial biota inhabiting tropical equatorial forests during mid-Cretaceous time. In contrast to the large amount and great diversity of terrestrial species retrieved so far, aquatic biota constitute rare inclusions. Here we describe the first freshwater snail ever preserved in amber. The new species Galba prima sp. nov. belongs in the family Lymnaeidae, today a diverse and near globally distributed family. Its inclusion in terrestrial amber is probably a result of the amphibious lifestyle typical of modern representatives of the genus. The finding of a freshwater snail on the Burma Terrane, back then an island situated at some 1500 km from mainland Asia, has implications for the dispersal mechanisms of Mesozoic lymnaeids. The Cenomanian species precedes the evolution of waterfowl, which are today considered a main vector for long-distance dispersal. In their absence, we discuss several hypotheses to explain the disjunct occurrence of the new species.

The study was made to assess the species diversity of avians, habitat type, their presence/absence in the different habitats and to produce a distribution map of globally threatened species in Khata Corridor forest of Bardia district. Species discovery curve and richness curve was produced through McKinnon list method in which each list contains 15-species. Habitat type was distinguished by modified DAFOR scale. Riverine sissoo-khair forest, Moist-mixed forest, and Riverine grassland were found to be prominent habitat type in the intensive study area. Distribution map of threatened species was assembled through Arc View 3.2a. Shannon's Index of Diversity (H = 3.114) and species evenness (0.629) indicates the high species diversity of avians in Khata corridor forest. Further study is essential to incorporate remaining part of the forest and to survey winter birds.

Abstract A new species of the cyclopoid copepod genus Paramacrochiron, P. tridentatum, which is parasitic on the rhizostome medusa, Versuriga anadyoneme (Maas, 1903), is described from Vietnam. This is the tenth species within the genus. The new species is distinguishable from other congeners by the combination of the following features: (1) female second maxillipedal segment with 3 acutely pointed processes terminally; (2) female leg 4 endopod as long as or slightly longer than exopod; (3) male maxilliped with a small, acutely pointed process at subterminal corner of the first segment and a row of relatively coarse spinules along the inner margin of the second segment. The present study most probably implies a high species diversity of Paramacrochiron in the tropical and subtropical waters of the Indo-West Pacific region.

A New Species

New taxa of the family Ropalomeridae from Costa Rica are described, and additional records of ropalomerid flies fromMexico and Central America are provided. The new genus and species Acrocephalomyia zumbadoi can be easily distin-guished from all other ropalomerid genera by the following combination of characters: angular forward projection of head,absence of ocelli, flat face, bare arista, long scutum, and scutellum triangular-shaped and dorsally flattened with only onepair of apical bristles with bases approximated. The new species Ropalomera aterrima can be recognized from congenersby remarkable differences of the head, the shape of the scutellum, the absence of scutal vittae, fumose wings, and by theblack coloration of the body, ocellar bristles large, one postpronotal bristle, scutum without pollinose vittae and flat scutellum. Lenkokroeberia chryserea Prado and Kroeberia fuliginosa Lindner are newly confirmed for Costa Rica.

This study reviews the family Macrochelidae in Turkey, with new information about species diversity. Nothrholaspis scutivagus sp. nov., Macrocheles niksarensis sp. nov. and Holostaspella bidentata sp. nov. are described as new species from Turkey. Nothrholaspis scutivagus has a characteristic dorsal shield chaetotaxy, and post-genital platelets that are sometimes fused to the ventri-anal shield. Macrocheles niksarensis has 29 pairs of pilose dorsal shield setae and a machete-like cheliceral dorsal seta. The genus Holostaspella is recorded from Turkey for the first time, on the basis of H. bidentata. Macrocheles peniculatus and M. insignitus are reported from Turkey for the first time. Also, Macrholaspis recki and M. evansi are presented here with some notes on the Turkish specimens.

ABSTRACTResinicium, belonging to Hymenochaetales, Agaricomycetes, is a worldwide genus of corticioid wood-inhabiting fungi. To improve the knowledge of species diversity within the Hymenochaetales, two dozen specimens from Asia-Pacific preliminarily identified to be members of Resinicium sensu lato were carefully studied from morphological and phylogenetic perspectives. From these specimens, a new monotypic genus Skvortzoviella, and five new species, viz. Resinicium austroasianum, R. lateastrocystidium, Skvortzovia dabieshanensis, S. qilianensis and Skvortzoviella lenis are described; moreover, a new basal lineage of Resinicium represented by a Vietnam specimen and three Chinese specimens of S. pinicola are identified. The six newly proposed taxa are morphologically compared with related genera and species, while the family positions of Resinicium, Skvortzovia, and Skvortzoviella within the Hymenochaetales are still ambiguous. In addition, the ancestral geographic origin of Resinicium, even though inconclusive, is now thought to be Asia-Pacific instead of tropical America as previously assumed.

High Species Diversity

AbstractStemming biodiversity loss requires strategic conservation guided by well-articulated and achievable targets, whether they be proactive (e.g., protect diverse places) or reactive (e.g., protect threatened species). Both types of targets can be effective, but there are trade-offs, especially for broadly-distributed ecosystems or taxa, such as migratory species, a group for which conservation has been challenged by limited knowledge of distributions throughout the annual cycle. We combined novel spatiotemporal distribution models with population trend data to first examine focal areas for the conservation of Neotropical migratory birds (n=112 species) during the non-breeding period in the Western Hemisphere based on a proactive approach (highest diversity) versus a reactive approach (strongest declines) to conservation. For the focal areas, we then assessed the extent of recent anthropogenic impact, protected area status and projected future changes in land cover using three shared socioeconomic pathways (Sustainability=SSP1, Business-as-usual=SSP2, Regional nationalism=SSP3). Spatial priorities were strikingly different when targeting areas of high species diversity, emphasizing southern Mexico and northern Central America, versus areas with more severe declines across species, emphasizing the Andean cordilleras of South America. Only a fraction of the non-breeding region (1.4%) met targets for diversity and decline, mostly in southern Central America. Current levels of protection were similar for the two targets. Areas prioritized to conserve high species diversity have experienced less recent anthropogenic impact than areas prioritized for decline but are predicted to experience more rapid land conversion to less suitable open, agricultural landscapes in the next three decades under both an SSP1 and SSP2 scenario. Only the SSP3 scenario projected similar conversion rates for the two targets. Our findings indicate how even within taxa, efficient conservation efforts will depend on the careful consideration of desired targets combined with reliable predictions about the locations and types of land cover change under alternative socioeconomic futures.

The large pantropical millipede genus Stemmiulus, which currently encompasses more than 150 species, i.e. the bulk of the species diversity of the family Stemmiulidae and entire order Stemmiulida, is shown to comprise seven species in Cameroon, including three new ones: S.ongot Nzoko Fiemapong & VandenSpiegel, sp. n., S.uncus Nzoko Fiemapong & VandenSpiegel, sp. n., and S.mbalmayoensis Nzoko Fiemapong & VandenSpiegel, sp. n. In addition, S.beroni Mauriès, 1989, previously known only from the type locality in Nigeria, is recorded from Cameroon for the first time, also being redescribed based on new samples. A key is given to all species of the genus encountered in the country, based on male gonopodal conformation, except for S.camerunensis (Silvestri, 1916), which was described only from female and juvenile material.
