We report a new locality record for Pristimantis palmeri, an endemic species to Colombia associated to forest and weeds in open areas of Choco, Risaralda, Quindío, Valle del Cauca, and Cauca (900 – 2,400 m.a.s.l.). This report expands its geographical distribution in 177 km toward south and suggests the existence of a discontinuous distribution in the western slope of the Central Cordillera of Colombia.

Endemic Flora

For the purpose of the present study we considered as Italian endemics those specific and subspecific taxa occurring in Italy that are not found elsewhere with the exception of Corsica (France) and Malta. This study presents an updated list of the endemic taxa in the Italian flora, including their geographical distribution at regional level. Italy is characterized by 1371 endemic species and subspecies (18.9% of the total vascular flora): three taxa belong to Lycopodiidae, one to Polypodiidae, two to Pinidae and 1365 to Magnoliidae (three paleoherbs, 221 monocots and 1144 eudicots). The endemic flora belongs to 29 orders, 67 families and 304 genera. Sicily, Sardinia, Calabria and Abruzzo are the four regions richest in endemics. About 58% of endemics are confined to a single administrative region. The most represented orders, families and genera are: Asterales, Caryophyllales and Asparagales, Asteraceae, Plumbaginaceae and Caryophyllaceae, Limonium, Centaurea and Hieracium, respectively. The phytogeographic isolation of Sardinia and Sicily and the separation of peninsular Italy from Northern Italy is confirmed. The relative isolation of Puglia with respect the remaining southern Italian pensinsular regions is also confirmed. Alpine region endemics (from northern Italy) are underrepresented.

Island Group

The four islands of the Tristan da Cunha-Gough Island group are very isolated. They contain a unique fauna and flora. Knowledge of these is very incomplete in important respects. Such knowledge could not only help towards understanding the origins of the geographical distribution of plants and animals, it could also throw valuable light on the factors governing colonization of isolated regions. But it is not only the unique biota which is of scientific interest in these islands. We have here a natural ecological balance between the endemic species of an impoverished and therefore simple fauna and flora. Such islands could thus allow us to study with comparative ease the factors which control ecological stability; a study of the great importance to mankind today. Moreover, fortunately there have now been found in these islands evidence of datable remains of the geologically recent biota, so that there is a reasonable chance that we shall one day be able to trace the ecological evolution in time.

<p class="Pa1"><strong>Background</strong>: Floristic knowledge of Northwestern (NW) Mexico was mainly carried out by American botanists until the first half of XX century.</p><p class="Pa1"><strong>Question</strong>: Do the ancient and recent botanical explorations carried out in the study area, are already enough to document in a conclusive way both the floristic and structural composition?</p><p class="Pa1"><strong>Methods</strong>: The authors are botanists and managers of the herbaria included in the floristic compilation (BCMEX, HCIB, SD, and USON), each herbarium has been devoted to document the flora of the states of NW Mexico in the last three decades. The floristic information was obtained mainly of the herbaria databases (around 110,000 entries), historic bibliographic information and recent collects from the same authors. The databases consulted are composed by 27,117 collect sites.</p><p class="Pa1"><strong>Results</strong>: The final database obtained consists of 5,865 taxa at the species level and intraspecific categories. By state, Sonora is the most biodiverse with 3,762 taxa, Baja California has 2,583 and Baja California Sur has 2,070. The Mexican NW is relatively poor in total number of species, but the number of endemic taxa is high. Within this region there are 941 endemic species, where 294, 391, and 79 correspond to the states of Baja California, Baja California Sur, and Sonora, respectively; in addition, there are 177 endemic species shared among these three states. The NW region also has 18 endemic genera, included in 10 families.</p><strong>Conclusions</strong>: As result of this review, there is excellent floristic knowledge background for NW Mexico, but there are still geographic areas still inaccessible, which includes all kind of topography, that explored could increase the total flora and endemism rate. Presently, the climate change put into risk the species survival, and hence it is a priority that conservation programs be established especially in terms of endemic species, since many of them have a restricted geographical distribution.

Recent exploration on the mountains of Northern Mindanao, Philippines resulted in the recollection of Etlingera pubimarginata, an enigmatic endemic species recollected after a lapse of over a century. An amended taxonomic description with colour photographs as well as comparative morphology to its allied species, geographical distribution, and conservation status are provided.

A taxonomic list of recorded Symphypleona from Mexico is presented. Data also includes a nomenclatorial update, distribution per political entity and habitat preferences. It is indicated that 28 genera and 73 species are currently distributed in 23 of the 32 states of Mexico. Quintana Roo represents the most diverse state (27 species) followed by Jalisco and Hidalgo (20 spp.). Reviews consulted indicate that eleven endemic species have been recorded so far from Mexico. According to the literature, one-third of the collected specimens across Mexico from leaf litter have yielded Symphypleona. The three most diverse genera recorded are, Sminthurides with 9 species, Sminthurinus and Sminthurus with 7 species each.

Valle Del Cauca

The beetle families Carabidae and Cicindelidae, with about 40 000 species worldwide, play an increasing role in biodiversity conservation and ecological studies in Colombia, which makes a faunistic update all the more necessary. We present and analyze a checklist of the species so far described or registered from Colombia until 2020, based on published studies, and their distribution data at the department level. Carabidae are represented by 625 species and Cicindelidae by 100. Magdalena, Cundinamarca and Valle del Cauca are the departments with the highest record numbers of Carabidae, while Cicindelidae are most frequently cited from Valle del Cauca, Antioquia and Meta. The greater sampling effort in these regions is likely due to the accessibility of their natural areas from the main towns. The geographical distribution of Cicindelidae is better documented, with only 17 % of the species without mention of specific localities within the country, against 40 % in Carabidae. Hyper-diverse regions, such as the Chocó and the Amazon, are underrepresented. The number of species currently recorded is therefore estimated to be much lower than true diversity for both families.

A new, narrowly endemic species from the Andean western slopes of central Peru, Chusquea limensis (Poaceae, Bambusoideae, Bambuseae), is described and illustrated. Identification keys and a comparative table based on vegetative and reproductive characters, including morphologically similar species such as C. huantensis, C. inamoena, C. scandens and C. tarmensis, as well as habitat and geographical distribution notes, are included. Additionally, anatomical and micromorphological characters of the culm and foliage leaf blades of the new species are presented, as a valuable tool for the identification of sterile specimens.

Cladoceran Species

An updated checklist of cladoceran orders Ctenopoda and Anomopoda from inland aquatic habitats in Venezuela is provided, containing a total of 112 species grouped into 39 genera. Recorded cladoceran species of Venezuela represent 30% of the world’s described 370 species of Ctenopoda and Anomopoda. The most representative genera are Alona, Diaphanosoma, Moina, Macrothrix, and Chydorus with 19, 10, 7, 6, and 5 species, respectively. Most records (45%) are Neotropical and about 4% are endemic species. Some aspects related to geographical distribution and species richness in the Venezuelan hydrographic basins are briefly discussed.
