Hemerobiidae from Deceit Island: the Southernmost Neuroptera in the Americas

ABSTRACT The Neuropteran fauna on the most meridional part of South America is relatively scarce. Two families, Hemerobiidae and Coniopterigydae, have been recorded so far. Accordingly, only a few species have reached the south of Tierra del Fuego. Currently, the southernmost records of these species, Hemerobius chilensis Nakahara, 1965 and Megalomus flinti (Nakahara, 1965), are from Puerto Williams, Navarino Island (54°56′S 67°37′W), which makes them the southernmost distributed neuropterans in the continent. Here we provide the first records for two Neuroptera species, Hemerobius nekoi Monserrat, 1996 and Megalomus flinti; from Deceit Island, a remote subantarctic island within the Cape Horn archipelago (55°51′41″S 67°08′31″W). The records provided makes these species the southernmost recorded lacewings in the continent; extending the known distribution of neuropterans in South America nearly 110km towards the south.

A review of the genus Microcrambus Błeszyński, 1963 (Lepidoptera, Pyraloidea, Crambinae) in Colombia, with descriptions of two new species / El género Microcrambus Błeszyński, 1963 (Lepidoptera, Pyraloidea, Crambinae) en Colombia, con descripciones de dos especies nuevas

ABSTRACT Although consisting of 53 described species, the New World genus Microcrambus Błeszyński contains many more undescribed species. This study aims to bring a small contribution to the knowledge on the diversity of Microcrambus based on the fauna of Colombia. A literature review of the known fauna of the country was performed and specimens were collected at light in 2018. Five species are recorded for the first time from Colombia, including two new species (M. arevaloi Landry and M. leticiensis Landry) from Leticia, Amazonas Department, described based on morphological and molecular data. The habitus of both sexes, as well as the genitalia are illustrated for the new species. The male genitalia of one Colombian specimen of Microcrambus elpenor Błeszyński are also illustrated as they were found to differ slightly with the drawing provided in the original description. A list of the eight species found to presently represent the known fauna of Microcrambus in Colombia is given, along with comments on their known distribution, including new country records.

RESUMEN Aunque ya consta de 53 especies, el género del Nuevo Mundo Microcrambus Błeszyński contiene muchas más especies sin describir. Este estudio tiene como objetivo realizar una pequeña contribución al conocimiento sobre la diversidad de Microcrambus, basado en la fauna de Colombia. Se realizó una revisión de la literatura de la fauna conocida del país y se recolectaron especímenes con trampas de luz, en 2018. Se registran cinco especies por primera vez para Colombia, incluidas dos nuevas (M. arevaloi Landry y M. leticiensis Landry), de Leticia, Departamento de Amazonas, descritas con base a datos morfológicos y moleculares. El habitus de ambos sexos, así como los genitales, se ilustran para las nuevas especies. También, se ilustran los genitales masculinos de un espécimen colombiano de Microcrambus elpenor Błeszyński, ya que se halló que difieren ligeramente con el dibujo proporcionado en la descripción original. Se proporciona una lista de las ocho especies que, actualmente, representan la fauna conocida de Microcrambus en Colombia, junto con comentarios sobre sus distribuciones conocidas, incluidos nuevos registros para países.

Veliidae (Insecta: Heteroptera: Gerromorpha) from Colombia: Description of a new species and of the male of Euvelia meta Molano, Moreira & Morales, 2016

Abstract Stridulivelia (Aenictovelia) chocoana sp. nov. (Heteroptera: Veliidae: Veliinae) is described based on specimens from the Colombian department of Chocó. The new species is diagnosed by pronotal humeral angles, body length, male hind trochanter and paramere shape. Furthermore, we describe and illustrate the previously unknown male of Euvelia meta Molano, Moreira & Morales, 2016 (Heteroptera: Veliidae: Microveliinae) and its range is extended to Amazonas and Vichada departments.

Mycale alagoana sp.nov. and two new formal records of Porifera (Demospongiae, Poecilosclerida) from the shallow-water reefs of Alagoas (Brazil) / Mycale alagoana sp.nov. e dois novos registros formais de Porifera (Demospongiae, Poecilosclerida) dos recifes rasos de Alagoas, Brasil

The Porifera occurring at Alagoas State reefs (north-eastern Brazil) are still little-known, with few species listed and even fewer formally described. From a total of 48 species recorded from the state, only eight belong to the Poecilosclerida, including those (re)described in this study. Here we describe a new species, Mycale (Mycale) alagoana sp.nov., and redescribe two species: Lissodendoryx (Lissodendoryx) isodictyalis (Carter, 1882) and Mycale (Naviculina) diversisigmata Van Soest, 1984, both first formal redescriptions from the Southwestern Atlantic. Additionally, Mycale (Aegogropila) escarlatei Hajdu et al., 1995 is here reported from Alagoas for the first time, in discussing the difficulties inherent to recognition in the field of small crustose Mycalids with neatly reticulated surfaces.

Os poríferos dos recifes do Estado de Alagoas (nordeste do Brasil) são ainda pouco conhecidos, com poucas espécies formalmente descritas. Dentre as 48 espécies de Demospongiae registradas para o estado, apenas oito pertencem à Ordem Poecilosclerida, incluindo o material (re)descrito aqui. No presente estudo se descreve uma espécie nova Mycale (Mycale) alagoana sp.nov., e duas espécies são redescritas: Lissodendoryx (Lissodendoryx) isodictyalis (Carter, 1882) e Mycale (Naviculina) diversisigmata Van Soest, 1984, ambas, primeiras redescrições formais para para o Sudoeste do Atlântico. Adicionalmente, Mycale (Aegogropila) escarlatei Hajdu et al., 1995 é registrada aqui para Alagoas pela primeira vez, na discussão das dificuldades inerentes ao reconhecimento em campo de pequenos Mycalídeos incrustantes com superfícies claramente reticuladas.

Scorpion fauna of the island of Fernando de Noronha, Brazil: first record of Tityus stigmurus (Thorell 1877) (Arachnida, Buthidae) / Escorpiofauna da ilha de Fernando de Noronha, Brasil: primeiro registro de Tityus stigmurus (Thorell, 1877) (Arachnida, Buthidae)

A survey of the scorpion fauna of the Island of Fernando de Noronha, Pernambuco (Brazil), was carried out in October 2005. Methods included active collecting and pitfall traps in several areas of the island under different degrees of human-caused alteration. Forty four scorpions, belonging to two species were collected: Isometrus maculatus (DeGeer, 1778), previously listed for the Island, and Tityus stigmurus (Thorell, 1877), here recorded for the first time. This species was probably introduced via cargo shipments from the continent and offers risk to the local population due to the gravity of the accidents.

Foi conduzido um levantamento sobre a escorpiofauna de Fernando de Noronha, Pernambuco (Brasil), em outubro de 2005. Os métodos incluíram coleta ativa e armadilhas de queda em várias regiões da ilha, sob diferentes graus de alteração antrópica. Foram coletados 44 escorpiões de duas espécies: Isometrus maculatus (DeGeer, 1778), previamente listada para a ilha, e Tityus stigmurus (Thorell, 1877), registrada pela primeira vez. Trata-se de uma espécie provavelmente introduzida através do tráfego de material do continente, e que oferece risco à população local, devido à gravidade dos acidentes.
