Context – The species of Psychotria subgen. Heteropsychotria have recently been transferred to Palicourea, following the results of molecular studies showing that they form a monophyletic group with the latter. This paper presents a conspectus of Palicourea sect. Potaroenses (formerly Psychotria subgen. Heteropsychotria sect. Potaroenses), discusses the characters of the section, and provides a key to the species. A new species recently collected in French Guiana is described and illustrated, and one new combination is included.Methods – This paper is based on direct study of herbarium material from BR, CAY, F, K, L, NY, U and US, and additional type specimens from F, K, MO, P, RB, and VEN were consulted online. Two of the species, including the new one, have also been studied in the field. Common practices of herbarium taxonomy have been applied.Results – Palicourea sect. Potaroenses is characterized by the capitate inflorescences surrounded by an involucre of 4–20 elliptic, yellow to red bracts, the leaves with lateral veins strongly ascending and almost reaching the margin, the long tubular calyx, the unusually long corolla tube for the genus, and the peculiar stipules, consisting of an internal sheath and two interpetiolar pieces connate to the sheath by their central part. The section includes eight species: Palicourea aetantha (Sandwith) Delprete & J.H.Kirkbr., P. fanshawei (Standl.) Delprete & J.H.Kirkbr., P. formosissima (Steyerm.) Delprete & O.Lachenaud, P. phaneroneura (Standl.) Borhidi, P. potaroensis (Sandwith) Delprete & J.H.Kirkbr., P. psittacina (Steyerm.) Delprete & J.H.Kirkbr., P. spectabilis (Steyerm.) Borhidi, and the new species P. aurantiosplendens O.Lachenaud & Delprete. The latter is most similar to P. psittacina, from which it can be separated by the dense patent indumentum of the stems, calyx lobes, and inner side of the bracts, and the smaller size of the latter; it also resembles P. spectabilis and P. formosissima, but differs in having the stipules with four lobes on each side (vs. two), the bracts nearly glabrous outside (vs. densely hirsute on both sides) and the calyx lobes much more pubescent than the tube (vs. the calyx uniformly hairy). It is only known from a small area on the upper Sinnamary River, north-central French Guiana, and is evaluated as Endangered (EN D1) according to IUCN criteria.

Snakes of the genus Cerberus Cuvier, 1829 occupy a unique, widespread coastal distribution and have a salt-tolerant physiology that allows members of the genus to move across a wide range of salinities from full salt water to freshwater. Cerberus nomenclature is revised based upon morphology and builds on previous molecular studies. Three species have been recognized by recent workers, here we recognize five species: the South Asian C. rynchops (Schneider 1799); the Southeast Asian-Philippine C. schneiderii (Schlegel 1837), a new combination; the freshwater Philippine endemic C. microlepis Boulenger 1896; the Australopapuan C. australis (Gray 1842); and a new species from Micronesia. We also select a lectotype for Homalopsis schneiderii Schlegel based upon a figure published in 1837 and restrict the type locality for this species to Timor. Evidence is also presented for a population of Cerberus australis in Indonesia, west of Weber’s Line.

Pothea carpinteroi sp. nov. (Hemiptera: Heteroptera: Reduviidae: Ectrichodiinae) is described based on two male specimens from Mexico. Pothea aeneonitens Stål, 1864 and P. lugens (Fabricius, 1803) are recorded from French Guiana for the first time. Taxonomical notes on these latter two species and P. haematogaster Breddin, 1903 and P. sanguiniventris Miller, 1956 are also presented. A lectotype is designated for P. lugens. Pothea centralis Walker, 1873, treated as a junior synonym of P. lugens by previous authors, is regarded as a potentially valid species. Color variation in the sternites of males and females of P. frontalis (Lepeletier & Serville, 1825) are recorded for the first time. Photographs of the type specimens of P. aeneonitens, P. bivittata Champion, 1899, P. centralis, P. frontalis, P. haematogaster, P. halffteri Carpintero, 1980, P. lugens, P. maculata Champion, 1899, P. reyesi Carpintero, 1980, P. sanguiniventris and P. venatrix Hussey, 1953, are presented.

AbstractMichaelshaffera gen. n. is comprised of two species, M. maidoa (Schaus), new combination, the type species, described from French Guiana, and a new species, M. beckeri, here described from South America. The assignment of taxa to the Pyraloidea is based primarily on characters of the tympanal organs and immature stages. Michaelshaffera lacks a tympanal organ and the immatures are unknown. The rationale for the placement of this genus in the Pyraloidea and lower hierarchical ranks is discussed based on other morphological characters.

In a recent revision of Neobertiera, three new species were described and the distylous condition of this genus was reported for the first time. In the present paper, a new species, N. montedouradensis, from the state of Pará, Amazon Basin, is described, which represents a significant range extension and the first record of this genus for Brazil. This new species is unique within the genus by having hypanthia and fruits with trichomes conspicuously tuberculate at base. In addition, a new combination is proposed for a species from French Guiana recently named N. glomerata. A correction regarding the corolla size of N. pakaraimensis is included. In view of these taxonomic novelties, a key to the five species of Neobertiera is provided.

A new species of Myloplus Gill is described from Eastern Tumucumaque Mountain Range, drainages of the Oyapock and Araguari rivers between Brazil and French Guiana. The new species is diagnosed by having comparatively large scales on the flanks, resulting in lower counts when compared with congeners, i.e., 59 to 70 total perforated scales on lateral line, 31 to 35 longitudinal scales above lateral line, 24 to 29 longitudinal scales below lateral line, and 22 to 26 circumpeduncular scale rows. The new species most closely resembles Myloplus rubripinnis by sharing with this species a general rounded shape, a similar color pattern, and a high number of rays, i.e., 23 to 25 branched dorsal-fin rays and 35 to 38 branched anal-fin rays in the new species (vs. 24 to 25 and 32 to 40, respectively, in M. rubripinnis). After reviewing the available type-specimens of all Myloplus species, M. rubripinnis is re-diagnosed as having higher counts of branched dorsal-fin rays and anal-fin rays combined to tiny scales on flanks, i.e., 85 to 89 total perforated scales on lateral line, 38 to 45 longitudinal scales above lateral line, 33 to 42 longitudinal scales below lateral line, and 30 to 39 circumpeduncular scale rows.

AbstractA new nematode species Dichelyne (Cucullanellus) sciaenidicola sp. nov. is described based on specimens collected from the Whitemouth croaker Micropogonias furnieri (Desmarest) and the Argentine croaker Umbrina canosai Berg, from coastal waters of Argentina and Brazil. These nematodes were firstly identified as D. (C.) elongatus (Törnquist, 1931), a commonly reported species from M. furnieri in South American Atlantic waters. However, other species of Dichelyne have so far been reported from this host in the same area, namely D. (C.) rodriguesi (Pinto, Fábio et Noronha, 1970), D. (C.) amaruincai (Freitas, Vicente et Ibañez, 1969) and D. (Dichelyne) micropogonii Pereira et Costa, 1996. A careful re-examination of these parasites, as well as of type specimens of all species reported from M. furnieri, revealed that these nematodes represented a new species. The new species is distinguished from most of its congeners by having papillae 5–7 and 9 forming a subventral line close to cloaca, this feature is shared with other 6 species [D. (C.) dichelyneformis (Szidat, 1950), D. (C.) fraseri (Baylis, 1929), D. (C.) abbreviatus (Rudolphi, 1819), D. (C.) adriaticus (Törnquist, 1931), D. (C.) minutus (Rudolphi, 1819) and D. (C.) mariajuliae Alarcos, Timi, Etchegoin et Sardella, 2006)], which are readily distinguished by their body size, spicules length, distribution patterns of other papillae and position of the excretory pore and deirids. Also, D. (C.) elongatus from Umbrina canariensis (Valenciennes) from West Africa is established as a new species Dichelyne (Cucullanellus) yvonnecampanae sp. nov.; D. (C.) amaruincai from Pacific waters is considered as a valid species, D. (D.) micropogonii is regarded as species inquirendae and D. (C.) rodriguesi is identified as Cucullanus sp.
