The aim of the present study is to update the checklist of vascular plants endemic to Mongolia using previous checklists, publications, herbarium collections, and field observations. The revised checklist includes 102 endemic taxa (95 species, five subspecies, and two nothospecies) from 43 genera and 19 families. The majority of endemic taxa were distributed in western and central Mongolia, and high endemic species richness was identified in four phytogeographical regions, namely Mongolian Altai, Khangai, Dzungarian Gobi, and Gobi Altai, which harbor 49, 27, 20, and 16 endemic taxa, respectively. For each endemic taxon, we compiled information about growth form, conservation status (if already assessed), phytogeographical distribution, and voucher specimens. Data on each taxon’s type specimen were also collected, and the majority of the type specimens were accessioned at the LE (58 taxa), MW (20 taxa), and UBA (7 taxa) herbaria.

Liopropoma aragai Randall & Taylor 1988 is redescribed based on the holotype and non-type specimens from Japan and Taiwan. Diagnostic characters of the species and the status of Taiwanese specimens previously referred to L. aragai are reassessed. Liopropoma lemniscatum Randall & Taylor 1988, previously recorded only from the Pacific coast of Japan and the Ryukyu Archipelago, and L. lunulatum (Guichenot 1863), previously known from Okinawa Island (Japan), Guam, Réunion, Rarotonga and Tahiti, are redescribed, both being confirmed for the first time by voucher specimens from Taiwanese waters. A detailed description of each species and a key to Taiwan Liopropoma Gill 1861 is provided.

The results of a systematic survey of monogeneans collected from the gills of the African carp, Labeo coubie (Cyprinidae) from the Gambia River basins in the Niokolo-Koba National Park, Senegal, are presented. The following 11 previously described species belonging to Dactylogyrus and Dogielius (Dactylogyridae) are reported: Dactylogyrus retroversus Guégan, Lambert & Euzet, 1988, Dactylogyrus titus Guégan, Lambert & Euzet, 1988, Dactylogyrus falcilocus Guégan, Lambert & Euzet, 1988, Dactylogyrus decaspirus Guégan, Lambert & Euzet, 1988, Dactylogyrus oligospirophallus Paperna, 1973, Dactylogyrus jaculus Guégan, Lambert & Euzet, 1988, Dogielius anthocolpos Guégan, Lambert & Euzet, 1989, Dogielius clavipenis Guégan, Lambert & Euzet, 1989, Dogielius harpagatus Guégan, Lambert & Euzet, 1989, Dogielius complicitus Guégan, Lambert & Euzet, 1989, and Dogielius flagellatus Guégan, Lambert & Euzet, 1989. Three new species of Dactylogyrus with 2 haptoral bars are described as follows: Dactylogyrus yassensis n. sp., Dactylogyrus dembae n. sp., and Dactylogyrus leonis n. sp. The sclerotized structures of type and voucher specimens of Dactylogyrus cyclocirrus Paperna, 1973, Dactylogyrus omega Guégan & Lambert, 1991, and Dactylogyrus cf labeous Paperna, 1979 are illustrated for comparative purposes. The type specimens indicate that D. cyclocirrus is based on specimens of two different species, among which the lectotype is designated from the syntypes collected from Labeo cylindricus. Dactylogyrus cyclocirrus of Guégan et al. (1988) and D. cf labeous Paperna, 1979 are considered senior subjective synonyms of D. yassensis n. sp. and D. dembae n. sp., respectively.

Locality Information

The Sierra de Famatina System is one of the main areas of endemism within the Southern Cone, as well as one of the main diversity hotspots of Argentina. We present here the first checklist for Sierra de Famatina, which includes 909 taxa (species, subspecies, varieties and forms) of vascular plants from 77 families and 358 genera. Sixty-eight are new records for La Rioja province and 28 are endemic species. Voucher specimens, locality information and distribution are given for each taxon, and a brief analysis of the diversity, phytogeography of the flora and the type specimens is presented. Illustrations of the important endemics and type specimens from Sierra de Famatina are provided. Our results emphasize the necessity to give high priority to the Sierra de Famatina region in terms of the conservation of its flora.

On the taxonomy and distribution of Varanus salvator andamanensis Deraniyagala, 1944 (Reptilia: Varanidae), including a redescription of the type specimens and a discussion about its allopatric co-occurrence with V. s. macromaculatus on the Nicobar Islands

We provide a detailed redescription of the two original type specimens of the little-known, endemic Andaman water monitor, Varanus salvator andamanensis Deraniyagala, 1944. Examination of further voucher specimens allows for an expanded morphological diagnosis of this island taxon and comparison with other currently recognized subspecies of the wide-spread Southeast Asian water monitor. Based on the specimens examined, V. s andamanensis is characterized by a homogenous black dorsal background colour, with five to seven, more or less distinctive transverse rows of small spots or ocelli, light yellowish dots arranged sporadically between transverse spot/ocelli rows on the body, light yellowish coloured spots distributed sporadically throughout both forelimbs and hind limbs; 17–18 prominent rows of light spots continuing from base of tail to its tip dorsally with sporadically arranged dots on lateral sides of tail; and higher scale counts in transverse dorsal scale rows. Based on photographic evidence and examination of museum specimens, V. s. andamanensis inhabits both the Andaman and southern Nicobar Islands, which politically belong to the Republic of India. In addition, we confirm the presence of V. s. macromaculatus in the northern and central Nicobar Islands, thus providing evidence for the allopatric co-occurrence of two different water monitor subspecies in these remote archipelagos.

Cryptantha pterocarya (Boraginaceae), the winged nut popcorn flower, is distinguished in part by nutlets with marginal, typically lobed wings. Four varieties of this species have been accepted in recent treatments: vars. cycloptera, pterocarya, purpusii, and stenoloba. We tested the taxonomic discreteness, degree of variation, and geographic range of these varieties of C. pterocarya by examining material from numerous voucher specimens. We quantified differences among specimens by measuring or calculating twenty features of the corolla and fruit, the latter focusing on mature (fruiting) calyx and nutlet characteristics. Type specimens of all four varieties were examined and quantified, and all specimens were georeferenced and mapped. From our observations and measurements, we recognize two new morphological forms in the complex, termed the “pseudocycloptera” form and the “truncata” form. The “pseudocycloptera” form is similar to var. pterocarya but is homomorphic, with all four nutlets winged. The “truncata” form is similar to var. cycloptera, but is heteromorphic, with the odd nutlet having a reduced basal wing (somewhat truncate in shape) and having a slightly reduced gynobase stipe. We conclude that C. p. var. pterocarya, var. purpusii, and var. stenoloba should continue to be recognized as taxa at that rank. The “pseudocycloptera” form, although generally morphologically discrete in nutlet heteromophism, shows some intergradation, even within a specimen, of the typical form of C. p. var. pterocarya and exhibits no clear geographic discontinuity; it should thus be recognized as a homomorphic form of that taxon, which we formally name forma pseudocycloptera. Variety purpusii should continue to be recognized at that rank given its variation in nutlet wing morphology but with continuity in geographic range. Variety stenoloba should also continue to be recognized at this rank given its distinctive calyx and nutlet body size and shape, but having a quite limited geographic range. We conclude that what has been most commonly recognized as C. pterocarya var. cycloptera should be resurrected to the rank of species, as C. cycloptera, because of the distinctiveness of this taxon in three, discrete morphological characters, one of which (gynobase stipe) was previously undescribed. The “truncata” form, which shows some intergradation with C. cycloptera and lacks geographic discontinuity, should be recognized as a heteromorphic form of C. cycloptera, which we formally name forma truncata. A revised key is proposed to better accommodate the identity of these taxa and forms. We hope that future molecular studies will elucidate the phylogenetic relationships, character evolution, and geographic history of this interesting taxonomic complex.

Abstract The genus Pacifastacus contains two subgenera, Pacifastacus and Hobbsastacus, the latter of which contains the following four extant species, Pacifastacus (H.) gambelii (Girard, 1852), P. (H.) nigrescens (Stimpson, 1857), Pacifastacus (H.) fortis (Faxon, 1914), and P. (H.) connectens (Faxon, 1914), and one fossil representative, P. (H.) chenoderma. Pacifastacus (H.) fortis and P. (H.) connectens were re-examined on the basis of the type specimens and additional materials collected from California (P. fortis) and Idaho, as well as Oregon (P. (H.) connectens), USA. Lectotypes of P. connectens and P. fortis were designated, and subsequently the two species were re-described and illustrated with their full synonymies. Brief diagnoses of P. (H.) gambelii (Girard, 1852) and P. (H.) nigrescens are also provided. Detailed distributions of these species are presented based on data from voucher specimens. Following new findings in this study, the generic diagnoses of the genus Pacifastacus and the subgenus Hobbsastacus were updated.

Rollo Howard Beck (1870–1950) was a professional bird collector who spent most of his career on expeditions to the Channel Islands off southern California, the Galápagos Islands, South America, the South Pacific, and the Caribbean. Some of the expeditions lasted as long as ten years during which time he and his wife, Ida, were often working in primitive conditions on sailing vessels or camps set up on shore. Throughout these expeditions, Beck collected specimens for the California Academy of Sciences, the Museum of Vertebrate Zoology at Berkeley (California), the American Museum of Natural History, and the Walter Rothschild Museum at Tring, England. Beck was one of the premier collectors of his time and his contributions were recognized by having 17 taxa named becki in his honor. Of these taxa, Beck collected 15 of the type specimens.
