Two new species of the Plecoptera family Diamphipnoidae are described from Chile. Illustrations of the details of the male genitalia, female genitalia, and eggs are provided for these two new taxa. Diamphipnoa fresiae sp. nov. has the lowest latitudinal distribution of the genus in South America and the male is the smallest known for the family and has also unusual wing venation. Diamphipnopsis oncolensis sp. nov., also a small species is known only from the Parque Oncol, south of Valdivia, Chile. This species is characterized by its distinctive abdominal coloration pattern in both sexes of the adult. Additionally, the large diameter of the eggs and the prominent tubercles of the chorion characterize this new species.

The Australian species of the small heterogastrid genus Parathyginus Scudder, 1957 have been reviewed, resulting in the establishment of the junior subjective synonymy of P. doddi (Distant, 1918) with P. signifer (Walker, 1872), and the description of two new species, P. australis sp. nov. and P. acuminatus sp. nov. A redescription of the genus is provided with emphasis on male and female genitalia characters, along with a key to all included Australian species. Male genitalia, particularly the details of the aedeagus, have been rarely studied in this genus or for that matter the family Heterogastridae particularly due to the difficulty in inflating the inflatable sections. In this study, therefore, an attempt was made to fully inflate and describe the aedeagus of all the species included in this contribution, as well as of Heterogaster urticae (Fabricius, 1775), the type species of the oldest genus Heterogaster Schilling, 1829, of the family Heterogastridae.

Xiphocentron is the most species-rich genus of the pantropical family Xiphocentronidae. Among its five subgenera, Antillotrichia is the most diverse and the only one to occur in South America and Antilles. In the present study, two new species of Xiphocentron (Antillotrichia) are described from southern Atlantic Forest, Brazil. Xiphocentron gwarakeraba sp. nov. is diagnosed by the very elongate inferior appendage not bearing spines and with a simple mesal sclerite; X. muelleri sp. nov. is diagnosed by the inferior appendage with its ventral margin produced posterad and distinctly truncate. New distributional records are provided for X. acqualume, X. jaguare, X. kamakan, and X. maracanan. Additional non-genital diagnostic characters are presented for X. jaguare, and intraspecific morphological variations of forewing fork II (R3 and R4) and male genitalia are described for X. maracanan.

Baetidae is one of the most diverse families of Ephemeroptera. In South America this family now encompasses 27 genera and more than 130 species. The Guyana region is known for its extraordinary diversity and high level of endemism, which is, above all, remarkable at the tops of the isolated flat-topped table mountains – tepuis. Recently various international speleological expeditions to Churí-tepui explored the cave systems of this mountain. Here we describe a new genus of Baetidae recently found during the mentioned expeditions to Churí-tepui and Auyán-tepui. Parakari n. gen. can be distinguish from the other genera of this family, among other characters, in the nymphs by the absence of abdominal gills I, tarsal claws with subapical denticle larger than the others, right mandible with prostheca bifid and pectinate and with incisors positioned in obtuse angle to mola area, lingua with a tuft of setae, segment II of maxillary palpi with a concavity and a hole apically and segment II of labial palpi with a strong distomedial projection. In the adults the hind wings are absent and genitalia with segment II of forceps with a constriction, segment III elongate and long. Two new species are included in this genus; each one was collected at different tepui. A key and illustrations are included.

The genus Frisilia Walker of the world is reviewed, with all of the 31 known species including two new species, F. cornualis sp. nov. and F. nesiotes sp. nov. The genus can be divided into the nesciatella and the anningensis species groups, on basis of the presence or absence of a median process of the juxta in the male genitalia. For all of the known species, we provide photos of adults and their male or female genitalia, all available taxonomic information including original references, type localities, type depositories, sources of available specimens, geographical distributions, and some recently collected data of the species. Frisilia striapunctata Wu is transferred to the genus Homaloxestis Meyrick, due to the normal slender labial palpus of the male and its wing venation. Frisilia drimyba Diakonoff (1967), known from the Philippines, is excluded from the genus Frisilia because of its lanceolate forewing with sharply pointed apex.

Two new species of Oecobiidae are described from Central and South America, representing the first native members of the family recorded south of Mexico. Oecobius eberhardi sp.nov. is described based on male and female specimens collected from two localities in Costa Rica. Platoecobius kooch sp.nov., the second species in the genus, is described from female specimens collected in Southern Argentina. A new diagnosis is proposed for the genus Platoecobius Chamberlin & Ivie, 1935, which now includes one species endemic to the south-eastern USA and another from Argentinean Patagonia.

The genus Vansoniella gen. n. is established to accommodate the species V.chirindensis sp. n., collected in Zimbabwe by Van Son in 1937. The new species differs externally from other African taxa by translucent fore- and hindwings in the male sex. The wing venation is highly derived and the male genitalia are also structurally different from other genera. The genus occupies an isolated position within the family.

In the present paper, Flavina Stål is reviewed and a key to species is provided. Two new species, F. nigrifrons Zhang and Che, sp. nov., and F. nigrifascia Che and Wang, sp. nov., are described and illustrated, and F. hainana (Wang and Wang) is redescribed and illustrated, especially to show its male genitalia. The genus is compared to Fortunia Distant and comments are given on the family placement of the superficially similar genus Mahanorona Distant.

Five species and one undetermined species, belonging to six genera of the Syringophilidae (Acari: Prostigmata), are recorded from Argentina (South America). Two new species are described and figured: Syringophiloidus tarnii sp. n. from the Huet-huet Pteroptochos tarni (Passeriformes: Rhinocryptidae) and Aulobia paraguaiae sp. n. from the Magellan Snipe Gallinago paraguaiae (Charadriiformes: Scolopacidae). Four new host species of the family Syringophilidae are given.

The study of specimens, collected by David Agassiz in several African countries and in Madagascar, together with some specimens collected by Wolfram Mey, enabled not only the confirmation of some country records, but also the description of two new species (Epermenia (Calotripis) larseni and E. (C.) albofasciata), the description of the hitherto unknown female genitalia of Epermenia minuta Gaedike, 2004 and Ochromolopis namibica Gaedike, 2004 and the male genitalia of Ochromolopis xeropa (Meyrick, 1909). Two first records (Africepermenia tanzanica Gaedike, 2004 and Phaulernis montuosa Gaedike, 2013) for Zimbabwe and one for Kenya (Epermenia triacuta Gaedike, 2013) were made. A distribution list showing hitherto known occurrence of the family in the Afrotropics is presented.

During examination of new material of Burmese amber three individuals of Tarachoptera were discovered. The inclusions are sufficiently well preserved and allow identification and description of these rare, fossil insects. The species belong to the family Tarachocelidae and are described as Kinitocelis macroptera spec. nov. (†) and Retortocelis spicipalpia spec. nov. (†). The species and their preservations are described in detail, and photos and line drawings are provided for wing venation, head, mouthparts, and abdomen. The hitherto described species of Tarachoptera are summarized in a checklist.   Taxonomic acts Kinitocelis macroptera Mey & Wichard, spec. nov. – urn:lsid:zoobank.org:act:E0B1624A-C69E-4B53-851F-4368AC21C614Retortocelis spicipalpia Mey & Wichard, spec. nov. – urn:lsid:zoobank.org:act:9778E7E2-EEFE-4DC5-B891-54DF114D525C
