The ongoing treatments for the Flora of the Guianas (Guyana, Surinam, and French Guiana) and the monographic study of the tribe Sipaneeae prompted a revision of Neobertiera, discovering the distylous condition of this genus, and three undescribed species, one probably restricted to Guyana, and two probably restricted to French Guiana. Because of these novel observations and the different kinds of inflorescence of the newly described species, a generic description, with yet another amendment, a key to the species, illustrations, and material examined are presented.

Three New Species

The Neotropical water scavenger beetle genus Chasmogenus Sharp, 1882 is a diverse lineage with 34 described species. Here, three new species from the southwestern margin of the Guiana Shield are described using an integrative approach combining adult morphology and molecular data: Chasmogenus clinatus sp. n. (Brazil: Amazonas, Venezuela: Amazonas), C. gironae sp. n. (Venezuela: Amazonas), and C. inpa sp. n. (Brazil: Amazonas). Examination of the male genitalia is essential for confident identifications and thus unassociated females may prove extremely difficult to identify. New distributional records in Brazil for C. acuminatus Smith & Short, 2020 are provided as well as habitus images of newly described species and an updated key to the species from Venezuela, Suriname, Guyana, French Guiana and northern Brazil.

Partial Revision

The genus Robinsonia Grote, 1866 is partially reviewed following a large DNA barcode campaign. In the Robinsonia praphoea Dognin, 1906 group three new species are described: R. simulans sp. n. from French Guiana, up to now confused with R. praphoea itself and then R. decaensi sp. n. and R. maranhensis sp. n. both from the lower Amazon. R. drechseli sp. n. is described from Paraguay and R. inexpectata sp. n., a species close to R. mera (Schaus, 1910) from Costa Rica, is described as new from Peru and Bolivia. Finally the full species status is confirmed for R. flavicorpus Dognin, 1910 which is found to be differentiable from R. marginata Rothschild, 1909. All types are figured along with the male genitalia for most and some female genitalia for all studied species.

A New Species

Background and aims – The genus Anemopaegma (Bignoniaceae) includes around 47 species and has its centre of diversity in Brazil. Here, we describe and illustrate a new species from French Guiana, Anemopaegma kawense, and compare it to the two most similar species, A. foetidum and A. granvillei. We further assess the conservation status of all three species.Material and methods – Morphological descriptions are based on herbarium specimens deposited at BM, BR, CAY, INPA, K, MO, P, SPF, and U, and, in the case of the newly described species, also on field observations. The conservation status assessments follow the IUCN Red List criteria.Key results – Anemopaegma kawense differs from both A. foetidum and A. granvillei by its densely villose twigs, longitudinally plicate leaflets with secondary veins not or hardly prominent below, and tertiary veins impressed below. It is further separated from A. foetidum by the leaflets that are villose below and the calyx that is entirely pubescent outside. On the other hand, A. kawense differs from A. granvillei by the densely lepidote outer surface of the corolla, shorter petiolules, leaflets with midrib impressed above, shorter bracts and bracteoles, inflorescence peduncle exceeding the rachis, and pedicels densely puberulous, not lepidote or only sparsely so at the apex. This species is endemic to the Kaw Mountain in north-eastern French Guiana, where it grows in low stunted forest on laterite; it is assessed as Endangered according to the IUCN criteria. New descriptions are provided for A. granvillei, which is newly reported from Suriname, and for A. foetidum, which is newly reported from French Guiana; these two species are assessed as Endangered and Least Concern, respectively. Lectotypes are designated for A. maguirei, which is here synonymised with A. foetidum, and for A. umbellatum, another synonym of that species. A key to the 12 species of Anemopaegma occurring in the Guianas is presented.

Another three new species of Riccia in section  Pilifer Volk are described from Namaqualand, namely  R. furfuracea, R vitrea and R. namaquensis. There are certainly more undescribed species present in that region, but species from there are often very difficult to distinguish: almost all have hyaline scales, the free-standing dorsal cell pillars need to be examined in living plants and the spore ornamentation is quite variable.

Three New Species

The Syrphidae genus Domodon Reemer, 2013 so far included two species, D. zodiacus Reemer, 2013 and D. peperpotensis Reemer, 2014, both recorded only from Suriname. Additional specimens belonging to this genus have been collected in many other localities in South and Central America. In this paper, the genus is revised and three new species are described: D. caxiuana sp. nov. (northern South America), D. inaculeatus sp. nov. (northern South America), and D. sensibilis sp. nov. (Costa Rica). The distribution of D. peperpotensis is extended to include French Guiana. Photographs of the type material of the new species and illustrations of male genitalia of all species are provided, as well as a key to species.

Three new species of fangblennies are described from Indonesia. Meiacanthus abruptus is described based on two specimens, 31.4–36.6 mm SL, from Komodo Island and color photographs of others from Bali. The combination of a white or yellow body color and a single dark mid-lateral stripe that is bluntly rounded at its terminus on the caudal-fin base distinguishes it from other single striped species. This new species closely resembles the allopatric M. vicinus, which has the mid-lateral stripe extending farther onto the caudal fin and tapering to a point. Meiacanthus erdmanni is described from the only known specimen, 35.8 mm SL, photographed and collected in 65–70 m in Cenderawasih Bay, western New Guinea. One of the deepest known species of Meiacanthus, it has two dark mid-lateral stripes and differs from other doublestriped species in having a series of dark blotches on the base of the dorsal fin and only 24 segmented dorsal-fin rays. Meiacanthus cyanopterus, another deep-water species, is described from seven specimens, 19.8–45.3 mm SL, collected in 40–65 m at three sites in Alor Strait. In life this species has a dorsal fin with a blue-violet stripe bordered above by a wide black stripe. An identification key is provided for all the striped species of Meiacanthus, including at least one additional undescribed species previously confused with M. abditus. Color photographs of other Meiacanthus species and some new distributional records are also given.

The species Depressaria albarracinella Corley, sp. n., Agonopterix carduncelli Corley, sp. n. and Agonopterix pseudoferulae Buchner & Junnilainen, sp. n. and the subspecies Depressaria saharae Gastón & Vives ssp. tabelli Buchner, ssp. n. are described. Depressaria albarracinella was first found in Spain in 1969 and recognised as apparently new but the specimens in NHMUK have remained undescribed. Additional Spanish material has been located in ZMUC and other collections and three specimens have been found from Greece. Agonopterix carduncelli. A single male of an unidentified Agonopterix of the pallorella group was found in Algarve, Portugal in 2010. A search for larvae in March 2011 was successful and one male and one female were reared from Carthamus caeruleus. Additional specimens of the new species have been located in collections from Spain, Greece and Morocco. Agonopterix pseudoferulae. A specimen from Greece with the name Agonopterix ferulae (Zeller, 1847) found in the Klimesch collection in ZSM had forewing markings which suggested that it might be a different species. Further specimens from Italy and Greece have been examined, among them two reared from Elaeoselinum asclepium (Apiaceae). Both genitalia and barcode show that this is an undescribed species. Depressaria saharae Gastón & Vives, 2017 was described very recently (Gastón and Vives 2017) from northern Spain with a brief description, and figures of two males and male genitalia. Here the new species is redescribed, and additional data on distribution and relationships of the new species added. The opportunity is also taken to show that Canary Islands specimens with the same male genitalia should be treated as a new subspecies D. saharae ssp. tabelli Buchner, ssp. n.

Pycnogonid material collected between August 2000 and August 2003 from Taiwanese waters at depths between 100 and 2620 m is described. The thirty-three specimens represent ten species, and include one hitherto undescribed species of each of the genera Nymphon, Colossendeis and Pycnogonum. There are no previously published records of pycnogonids from Taiwan. Nymphon polyglia sp. nov. has multiple cement gland pores on the femur and first tibia, and tarsus and propodus subequal in length. Colossendeis mycterismos sp. nov. has affinities with C. pipetta, but has a tarsus shorter than the propodus. Pycnogonum cranaobyrsa sp. nov. has a slender tapering proboscis, no auxiliary claws and pointed mid-dorsal trunk tubercles, with a pustulate integument and a rounded ocular tubercle. The cement-gland openings of Heterofragilia hirsuta are described.
