Ageniella Banks, 1912 is a paraphyletic group exclusive to the Nearctic and Neotropical regions. The genus has a remarkable morphological diversity among species and strong sexual dimorphism, hampering taxonomic studies of it. Herein, we add two new species to the Neotropical fauna of Ageniella: A. caerulea sp. nov. belonging to the subgenus Ameragenia and A. ruschi sp. nov. belonging to the subgenus Priophanes; both species are described and illustrated. A brief discussion of subgeneric characters and an updated taxonomic key to the species of Ageniella known from Brazil are provided.

Seventeen species of the family Gryllidae were reviewed and a Modicogryllus sindhensis is described herein as new. Four species, namely Acheta hispanicus Rambur, 1838, Gryllus septentrionalis F. Walker, 1869, Callogryllus saeedi Saeed, 2000, and Miogryllus itaquiensis Orsini & Zefa, 2017 are recorded as new country and state records. Differences between similar species and a taxonomic key to the species of Sindh are provided.

Phanera ferruginea (Roxb.) Benth. is reported as a naturalised species for the Flora of Singapore. This species of climbing legume is represented by Phanera ferruginea var. griffithiana (Benth.) Bandyop., Ghoshal & M.K.Pathak in Singapore. The status of the species in Singapore, which is known only from Bukit Timah Nature Reserve, has hitherto not been fully investigated. We provide a description of the species from Bukit Timah, a comprehensive account of its origin through literature records and herbarium specimens, along with a taxonomic key and field characters for the Phanera species of Singapore.

Casparya, one of the most species-rich sections of Begonia in the Neotropics with 44 species, is distributed from Costa Rica to Peru, with the highest diversity in the Colombian Andes. The section is morphologically well-differentiated and can be distinguished from other Andean cane-like begonias by the 3-horned fruit and multifid or un-divided styles. Here we describe eight taxonomic novelties for Casparya from Colombia, five species and three varieties, descriptions include illustrations, distribution maps, taxonomic comments, and assessments of conservation status. The five species described here are: Begonia diegoi, Begonia galeanoi, Begonia mamapachensis, Begonia perijaensis, and Begonia vinagrera; and the three new varieties are: Begonia kalbreyerii var. orquidensis, Begonia silverstonei var. brevipetiolata, and Begonia vinagrera var. pomecensis. We also present a taxonomic key for the 32 species of Casparya so far known from Colombia.

The new species Biancaea scabrida, currently only known from Peninsular Malaysia, is described and illustrated. The new species most resembles B. parviflora and B. oppositifolia in its inflorescence, but can be distinguished from both species by its sepals which have short stiff scabrid hairs, and its pistil which has stiff and hispid hairs. It also has alternately arranged leaves and inflorescence branches, a lack of a persistent suborbicular stipule, few pinnae per rachis (2–6 pairs) and relatively fewer leaflets per pinna ((3–)5–9 pairs). A provisional IUCN conservation assessment and a taxonomic key to Biancaea is also provided here.

A preliminary study of the genus Rosulabryum J.R. Spence in Chile is presented, with brief species descriptions, notes on ecology and distributions, and a taxonomic key. The following 12 species are confirmed with vouchered specimens; Rosulabryum andicola (Hook.) Ochyra, Rosulabryum billarderii (Schwägr.) J.R. Spence, Rosulabryum campylothecium (Taylor) J.R. Spence, Rosulabryum capillare (Hedw.) J.R. Spence, Rosulabryum coloratum (Müll. Hal.) J.R. Spence, Rosulabryum densifolium (Brid.) Ochyra, Rosulabryum longidens (Thér.) J.R. Spence, Rosulabryum macrophyllum (Cardot & Broth.) Ochyra, Rosulabryum perlimbatum (Cardot) Ochyra, Rosulabryum puconense (Herzog & Thér.) J.R. Spence, Rosulabryum rubens (Mitt.) J.R. Spence, and Rosulabryum torquescens (Bruch ex De Not.) J.R. Spence. Rosulabryum canariense (Brid.) Ochyra is tentatively excluded as the Chilean material can be referred to R. coloratum. Similarly, Rosulabryum viridescens (Welw. & Duby) Ochyra is tentatively excluded since the Chilean plants do not match the African type, but instead appear to be atypical plants of R. campylothecium.

Although Colombia is perceived as one of the most diverse countries in reptiles, the distribution of many microteiid lizards of the Alopoglossidae and Gymnophthalmidae families is still poorly known. This is particularly true for those species in the cis-Andean regions, in part due to the remoteness or socio-political issues within some of these territories. In order to elucidate the diversity and distribution of the cis-Andean microteiids in Colombia, in this study we present a review based on the examination of specimens deposited in the reptile collection at Instituto de Investigación Alexander von Humboldt, one of the most important Colombian biological collections, and data from the literature. We reported a total of 29 taxa, in which three are new records for Colombia and three are range extensions. Two species were assigned to species complex because their morphological determination was non-conclusive, and three were identified just to genus, since they may correspond to more than one entity or be currently non-described. We found that nine species are distributed in both the Amazonia and Orinoquia regions, nine are currently only present in the Amazonia and seven are in the Orinoquia. Based on our data, we highlight the importance of using local museums to increase the taxonomic and geographic data coverage, we discuss the taxonomic difficulties for some taxa, as well as the potential for future research and their constraints. Finally, we present a taxonomic key for the identification of the microteiids present in the Orinoquia and Amazonia regions of Colombia.
