ABSTRACT Hyphessobrycon itaparicensis was originally described from a small stream in the Itaparica coastal island, Bahia State, Brazil, and has been sampled in several coastal rivers draining Bahia and Sergipe States. Broad examination of type material and recently collected specimens resulted in the redescription provided herein. The presence of one humeral blotch, absence of pseudotympanum, and conservation aspects of H. itaparicensis are briefly discussed. Data obtained from the original description, paratypes and topotypes of H. sergipanus showed broad overlap with H. itaparicensis and absence of morphological diagnostic features supporting the recognition of H. sergipanus as a valid species. Thus, H. sergipanus is considered as junior synonym of H. itaparicensis. We emphasize the need of examining large population samples and type material of similar congeners to avoid improper propositions of new specific names.

Late Osagean to Meramecian Platycrinites and Eucladocrinus from Illinois, Iowa, and Missouri are redescribed and redefined from study of type material. Three of the oldest species were incorrectly synonymized with P. sarae, and this correction leads to a realignment of species systematics within Platycrinites. Accordingly, six species of Platycrinites and one species of Eucladocrinus are considered valid in the Keokuk Limestone through St. Louis Limestone of the stratotype area. Valid species include Platycrinites saffordi (Hall), P. sarae (Hall), P. georgii (Hall), P. pumilus (Hall), P. brevinodus (Hall), P. niotensis (Meek and Worthen), and Eucladocrinus millebrachiatus Wahsmuth and Springer. Nomenclatoral changes include the following: 1) P. sarae is redescribed and all junior synonyms are removed; 2) P. georgii is a valid senior synonym of P. bonoensis (White), P. aeternalis (Miller), P. boonvillensis (Miller), and P. cauducus; 3) P. pentagonus (Miller) is a junior synonym of P. niotensis; 4) P. pumilus is a valid senior synonym of P. prattenanus (Meek and Worthen), and P. monroensis (Worthen); 5) P. bloomfieldensis (Miller) is designated as a nomen dubium; and 6) Eucladocrinus millebrachiatus immaturus is a junior synonym of E. millebrachiatus.The evoluton of new species in Platycrinites was by a combination of cladogenesis and possibly anagenesis. Platycrinites sarae evolved from P. saffordi possibly through anagenesis, P. pumilus evolved from P. niotensis through cladogenesis, and P. hemisphaericus evolved through cladogenesis from P. brevinodus, although P. hemisphaericus does not occur in the geographic area of this study.

A checklist of all described species of Philonthina, a subtribe of the staphylinid tribe Staphylinini, known to occur in Central and South America (CASA) is presented. Included for each species, and for synonyms known from CASA, is a reference to the original description, type locality and type depository, and for each species the known distribution within and outside CASA. Type material was sought in the main European and American collections where it is deposited (BMNH, MNHUB, IRSNB and FMNH) and is summarized for all indigenous CASA species, with lectotypes designated for 16 names and confirmation of holotypes and prior designation of lectotypes when necessary. Based on recent phylogenetic work in Philonthina and our revision of types of CASA species of Philonthus Stephens, 1829 and Belonuchus Nordmann, 1837, some taxonomic changes are proposed. Thirty-one species of Philonthus are transferred to Belonuchus (16), Gabrius Stephens 1829 (14), and Bisnius Stephens 1829 (one) resulting in the following new combinations: B. abnormalis (Sharp 1885), B. celatus (Sharp 1885), B. corticalis (Sharp 1885), B. extremus (Sharp 1885), B. infimus (Sharp 1885), B. iteratus (Sharp 1887), B. latecinctus (Sharp 1885), B. lucilius (Sharp 1885), B. muticus (Sharp 1876), B. optatus (Sharp 1885), B. platypterus (Sharp 1885), B. rufiventris (Sharp 1887), B. rufocaudus (Sharp 1885), B. rufopygus (Sharp 1885), B. serraticornis (Sharp 1876), B. supernus (Herman 2001), G. approximans (Sharp 1885), G. armatipes (Sharp 1885), G. atricolor (Sharp 1885), G. championi (Sharp 1885), G. dampfi (Bernhauer 1929), G. elegans (Sharp 1885), G. forsterianus (Scheerpeltz 1960), G. misellus (Sharp 1885), G. nugax (Sharp 1885), G. ovaticeps (Sharp 1885), G. peruvianus (Bernhauer 1916), G. planulatus (Sharp 1885), G. rusticus (Sharp 1885), G. serpens (Sharp 1885) and Bi. subaeneipennis (Bernhauer 1916). Endeius nitidipennis Solier 1849 is transferred to Gabrius, resulting in the following new combination, G. nitidipennis (Solier 1849). Leptopeltus carchiensis Chani-Posse & Asenjo 2013 is proposed as junior synonym of Philonthus divisus Sharp 1891, which is transferred to Leptopeltus Bernhauer 1906 resulting in a new combination: Leptopeltus divisus (Sharp 1891). Belonuchus penetrans Silvestri 1946 is transferred to Pridonius Blackwelder 1952 as a new combination. Lectotypes are designated for Atopocentrum mirabile Bernhauer 1906, Philonthus armatipes Sharp 1885, Ph. atricolor Sharp 1885, Ph. championi Sharp 1885, Ph. misellus Sharp 1885, Ph. planulatus Sharp 1885, Ph. rusticus Sharp 1885, Ph. serpens Sharp 1885, Ph. abnormalis Sharp 1885, Ph. celatus Sharp 1885, Ph. infimus Sharp 1885, Ph. latecinctus Sharp 1885, Ph. muticus Sharp 1876, Ph. platypterus Sharp 1885, Ph. rufocaudus Sharp 1885 and Ph. rufopygus Sharp 1885. Of the 543 currently known species of Philonthina reported from CASA, at least 14 are believed to be adventive from elsewhere, 56 may occur naturally elsewhere, and 473 (87%) are evidently endemic to this region. Of the 31 genera represented by these described species, 20 (65%) are endemic to CASA. One genus, Gabronthus Tottenham 1955, is adventive. However, the actual philonthine fauna of CASA will undoubtedly be much larger, and the generic composition highly modified, when the fauna is fully explored and studied within a phylogenetical framework.

Three species of wing-reduced Sciaridae, obtained from pitfall trap material collected from Nothofagus forests in Victoria, Australia, were examined. The females, which were all very similar, do not belong to any of the wing-reduced sciarid genera known to us so far. They instead appear to be females of the genus Austrosciara Schmitz & Mjöberg, 1924, according to the original description and illustration, and one of the species appears to be conspecific with Austrosciara termitophila Schmitz & Mjöberg. The shape of the male hypopygium, as well as the tibial organ of this species in both sexes show typical features of species previously classified as Ctenosciara Tuomikoski, 1960. The genus Ctenosciara Tuomikoski, 1960 n. syn. has therefore to be considered a junior synonym of Austrosciara Schmitz & Mjöberg. A further species described as Austrosciara pedibusa sp. n., based on female specimens, is typically characterized by a deep sensory pit on the basal segment of the palpus. The female of a third species, listed as Austrosciara sp., is illustrated as well.

The widespread Ophioderma hendleri sp. nov., from the Eastern Tropical Pacific (Mexico to Colombia) is distinguished from its congeners by having radial shields covered by granules, naked adoral shields, up to 11 arm spines, and by its brown and beige coloration. Ophioderma hendleri sp. nov. belongs to the group of species with naked adoral shields (i.e., O. pentacanthum H.L. Clark, 1917, O. variegatum Lütken, 1856), and it has frequently been misidentified as O. panamense Lütken, 1859 or O. variegatum. Therefore, the main aim of the present work was to describe Ophioderma hendleri sp. nov. and differentiate it from its congeners. The original description of O. panamense was incomplete; thus, we provide a redescription. Due to the confusion in previous designations of its type material, we designate a lectotype and paralectotype of O. variegatum. Finally, we expand the distribution range of O. pentacanthum to Cocos Island, Costa Rica. With this work, the total number of valid species of Ophioderma Müller & Troschel, 1840 in the world increases to 33 and in the Eastern Pacific to nine species.

ActinocrinitesMiller from the Mississippian stratotype region of Illinois, Iowa, and Missouri are redescribed and redefined based upon study of the type material and morphometric analyses.Actinocrinites pernodosus, A. lowei, A. jugosus, A. gibsoni, andA. probolosn. sp. are recognized as valid species that occur in these strata. A combination of both metric and qualitative characters must be used to differentiate these species.Actinocrinitesis known from the Montrose Chert Member of the Keokuk Limestone, the Keokuk Limestone, and the lower part of the Warsaw Formation, all late Osagean, in the stratotype region. In addition,Actinocrinites pernodosusandA. loweiare reported from the early Meramecian upper part of the Warsaw Formation, which is the first Meramecian occurrence ofActinocrinitesin the stratotype region.Actinocrinites probolosn. sp. was ancestral toA. lowei, and the latter was probably ancestral toA. pernodosus.Nomenclatural and systematic acts include the following: 1)Actinocrinites lowei(Hall, 1858) is the senior synonym ofActinocrinus brontesHall, 1860,Actinocrinites lobatus(Hall, 1860), andA. unicarinatus(Hall, 1860); 2)Actinocrinites jugosus(Hall, 1860) is the senior synonym ofA. augustatusMiller and Gurley, 1894; and 3) the concept applied incorrectly toA. lobatusby Wachsmuth and Springer (1897) represents a distinct species,Actinocrinites probolosn. sp.

The type material of Xiphophorus heckelii Weyenbergh, 1874 and X. obscurus Weyenbergh, 1877 has apparently been re-examined for the first time. Xiphophorus heckelii is confirmed as a junior synonym of Jenynsia multidentata (Jenyns, 1842). Xiphophorus obscurus is recognized as a senior synonym of Jenynsia pygogramma Boulenger, 1902, which is placed in synonymy. A lectotype and paralectotypes are designated for Jenynsia obscura (Weyenbergh, 1877).

Borradaile (1915) established Falciger Borradaile, 1915, as a subgenus of Periclimenes Costa, 1844, for nine species described by him as new to science: Periclimenes (Falciger) nilandensis Borradaile, 1915; P. (F.) affinis Borradaile, 1915; P. (F.) dubius Borradaile, 1915; P. (F.) compressus Borradaile, 1915; P. (F.) brocketti Borradaile, 1915; P. (F.) pottsi Borradaile, 1915; P. (F.) suvadivensis Borradaile, 1915; P. (F.) seychellensis Borradaile, 1915; and P. (F.) kolumadulensis Borradaile, 1915. Two years later, Borradaile (1917) increased the number of species in the subgenus up to 27, and designated Periclimenes petitthouarsi var. spinifera De Man, 1902, now considered to be Periclimenella spinifera (De Man, 1902), as the type species of the subgenus. Subsequently, Holthuis (1955) designated P. (F.) nilandensis as the type species because Periclimenes petitthouarsi var. spinifera was not included in the original description of Falciger by Borradaile (1915) (see ICZN 1999: Article 67.2). Earlier, Clark (1919) had proposed a replacement generic name Cuapetes Clark, 1919 for Borradaile’s Falciger, since the latter name is a junior homonym of Falciger Say, 1824 (Insecta: Coleoptera), Falciger Bucholz, 1869 (Arachnida: Arachnoidea), and Falciger Trouessart and Mégnin, 1883 (Arachnida: Arachnoidea) (see Holthuis 1993). Following current nomenclatorial rules, the type species of Cuapetes must thus be regarded to be P. (F.) nilandensis (see ICZN 1999: Article 67.8). Until now, shrimp taxonomists have always considered Cuapetes as a junior synonym of Periclimenes sensu lato (see Holthuis 1993; Chace and Bruce 1993), but a situation is herein corrected.

Although Acrossocheilus kreyenbergii has been treated as a valid species since its original description, the type locality and identity of this species have hitherto remained uncertain. It is shown in this study that its precise location of ‘Tinghsiang’ or ‘Pinghsiang,’ the type locality of Gymnostoma kreyenbergii Regan, is the present Pingxiang City, Jiangxi Province, in the Gan Jiang, a tributary flowing to the Boyang Lake system, or in the Yangtze River drainage. Observation of the type specimens of this species and further comparison with those of other barred congeners reveal that G. kreyenbergii is in fact a senior synonym of Barbus cinctus Lin.

Agnostus acadicus Hartt (in Dawson, 1868) was the first agnostoid trilobite to be described from Middle Cambrian strata in North America. It was later designated the type species of Acadagnostus Kobayashi, 1939. The original description of A. acadicus was based on two specimens, a cephalon and a pygidium, which are illustrated for the first time with photographs. These are interpreted to represent separate species, each belonging to a different genus. The holotype cephalon is reassigned as Peronopsis acadica, which is judged to be a subjective senior synonym of Agnostus fallax Linnarsson, 1869, and several other species-group taxa. Consequently, Acadagnostus is suppressed as a subjective junior synonym of Peronopsis. Agnostus fallax is the type species of Axagnostus Laurie, 1990, which also is suppressed as a subjective junior synonym of Peronopsis. The pygidium on which the original description of A. acadicus was based is reassigned to Hypagnostus parvifrons (Linnarsson, 1869).Peronopsis acadica, as emended, is a common, cosmopolitan agnostoid in open-marine lithofacies. It has an observed stratigraphic range from the Ptychagnostus praecurrens Interval-zone to the Ptychagnostus punctuosus Interval-zone.
