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.

A new genus of Naucoridae inhabiting a waterfall in Tamil Nadu state in southern India is described. Pogonocaudina Sites and Zettel NEW GENUS is diagnosed by a dense fringe of long hairs around the perimeter of the posterior abdominal segments, and by both males and females with a single segmented front tarsus with two pretarsal claws. Despite the lack of sexual dimorphism in the forelegs, this new genus is a member of the subfamily Laccocorinae, an assignment based on other characters consistent with this subfamily. Character states of this genus are compared with those of other Asian genera of Laccocorinae. The genus Diaphorocoris is reviewed and two new species are described here: Diaphorocoris arunachalami Sites and Zettel NEW SPECIES and D. kiliyur Sites and Zettel NEW SPECIES. Three species of Diaphorocoris are now known from southern India, and with one other species from Sri Lanka, a total of four species are now known in the genus. A taxonomic key is provided to distinguish all known waterfall-inhabiting Naucoridae in southern India and Sri Lanka.

We present an overview of the morphological diversity and geographical distribution of the anostracan genus Dendrocephalus Daday, 1908, and describe two new species: D. aranai sp. nov. from Jequitinhonha in the state of Minas Gerais and D. xikrini sp. nov. from the Carajás Mountains (Serra dos Carajás) in the state of Pará. These species have important similarities to D. goiasensis Rabet & Thiéry, 1996 and D. thieryi Rabet, 2006, respectively, but differ from them and each other through a combination of characters that are essentially unique to the endopods, and frontal appendage branch 2A and branch 2D. We also partly redescribe D. carajaensis Rogers, Gomes & Vieira, 2012, which shows a particular intra-populational variability in branch 2A and 2D III of the frontal appendage, a type of polymorphism that was also recently observed in D. orientalis Rabet & Thiéry, 1996 and which must now be taken into account in taxonomy. In terms of the distribution of species of Dendrocephalus in Brazil, we suggest that several other species are probably present in the Amazonian, Cerrado and Pantanal Biomes, which remain largely unexplored. A new taxonomic key for the identification of males of the Brazilian species is provided.

Elongationa gen. nov., a new leafhopper genus (Hemiptera: Cicadellidae: Ledrinae) with one new species, E. hyalina sp. nov., is described and illustrated in detail. A checklist and key to species in the genus Midoria are provided including a new species, Midoria curvidentata sp. nov., described in this paper.

Taxonomic revisions are the most reliable pathway in unfolding new species to the world. During such a revision of the genus Lagenandra in Sri Lankan, we came across two new species: Lagenandra kalugalensis and Lagenandra srilankensis from the Wet Zone of Sri Lanka. The two new species were studied in detail and compared with the morphology of the other species described in the genus, and based on field collected data conservation assessments were performed. A detailed description for the two new species and an updated taxonomic key to the Sri Lankan Lagenandra is presented here for easy identification. Recognizing two new endemic members enhances the number of Sri Lankan species of Lagenandra to eleven and global to nineteen. According to the IUCN red data category guidelines, L. kalugalensis qualifies for Critically Endangered category under Criterion B1ab (ii,iii,v) + B2ab (ii,iii,v) while L. srilankensis qualifies for Critically Endangered category under B1ab (iii, iv) + C2 (a) (i, ii). Hence, immediate conservation measures are imperative.

Two taxa of Amomum (Zingiberaceae), Amomum erythranthum and Amomum ampliflorum, from Putao, Kachin State of Northern Myanmar are described and illustrated as new to science. Amomum erythranthum is morphologically similar to A. subulatum and A. nimkeyense in having similar yellow flowers, but can be distinguished by its reddish floral tube, red anther connective, red and pubescent fruit. Amomum ampliflorum is similar to A. maximum, A. dealbatum and A. odontocarpum in white flower, but differs in its longer inflorescence and much larger flower. Two species, Amomum pauciflorum and Wurfbainia microcarpum are recorded for the flora of Myanmar for the first time. Data on ecology, phenology, distribution, conservation status, similarities to the related taxa, as well as colour photographs and line drawings of the type, and voucher specimens are provided for all reported taxa.

The genus Trichogorgia (Cnidaria: Octocorallia) is composed of mesophotic gorgonians, and has been traditionally included in the Family Chrysogorgiidae. The family is polyphyletic and in need of generic morphological reassessments. Herein, two new species of that genus are described, based on material deposited in the National Museum of Natural History—Smithsonian Institution. Additionally, we provide a taxonomic key to all species of Trichogorgia, also briefly discussing important characters of the group and closely related taxa.

A new genus and two new species of Sminthurinae are described. Keratosminthurus tapigu gen. nov. sp. nov. and K. calamitosus sp. nov. show a combination of features that redefines the subfamily Sminthurinae, such as a pair of sminthuroid chaetae, unguis without cavity, nine apical chaetae on tibiotarsus, 11 or more anterior dental chaetae, fourth antennal segment clearly subdivided into many (18 or more) subsegments, and asymmetric apex of mucro. The new genus also presents a striking sexual dimorphism, with modifications on male apical organ of antennal segment III, spines on the clypeus and special organs on the interocular area.

The aim of this study is to analyse the Nephtyidae from the Gulf of California. Previous studies about the family Nephtyidae from the continental shelf of the Gulf include 21 species of which seven have been synonymized by several authors, so that at present only 14 species are recognized. In this study, 1763 specimens of Nephtyidae from the continental shelf of the Gulf of California were examined. Eight species were identified, from which Aglaophamus longicirrata sp. nov. and Aglaophamus foliosa sp. nov. are newly described. Aglaophamus longicirrata sp. nov. is characterized by the presence of very long dorsal cirri in median parapodia and by having 16 rows of subterminal papillae with 3–7 papillae per row, and a pair of middorsal papillae on the proboscis. Aglaophamus foliosa sp. nov. is characterized by foliaceous long dorsal cirri; the proboscis bears 16 rows of subterminal papillae and an irregular number of papillae per row, from 5 to 15. A taxonomic key is presented for the species of Nephtyidae recorded from the continental shelf of the Gulf of California, including the two new species of Aglaophamus.
