Taxonomic Changes

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.

Roman Poetry

In his very valuable study of generic patterns in ancient poetry Francis Cairns assigns Propertius 2.28, [Tib.] 3.10 (4.4), and (tentatively) Ovid Am. 2.13 to the genre Soteria, that is works of congratulation and thanksgiving on the recovery from illness (or rescue from danger) of a friend, and he sees the resemblances between the poems as due to the elegists’ attempts to produce ‘dramatized’ examples of the genre, with the situation developing from the girl's illness at the beginning of the poem to her recovery at the end (Francis Cairns, Generic Composition in Greek and Roman Poetry (Edinburgh, 1972), pp.153–7). Cairns's arguments and interpretation of the poems should, I feel, be scrutinized carefully, especially since his classification of the poems has been accepted recently without demur by at least one scholar (Jennifer Moore-Blunt ‘Catullus XXXI and Ancient Generic Composition’, Eranos 72 (1974), 118 and n.50).

The Status

New specimens and a re-examination of their holotypes have clarified the status of five species of the extinct cicadomorphan family Hylicellidae from the Late Triassic (Norian) Mount Crosby Formation of south-eastern Queensland. All were found to be conspecific, resulting in the following synonymies: Mesothymbris Evans, 1956 (= Triassoscytina Evans, 1956, syn. nov. = (in part) Triassoscytinopsis Evans, 1956, syn. nov.), Mesothymbris perkinsi Evans, 1956 (= Mesothymbris woodwardi Evans, 1956, syn. nov. = Triassoscytina incompleta Evans, 1956, syn. nov. = Triassoscytinopsis stenulata Evans, 1956, syn. nov. = Triassoscytinopsis aberrans Evans, 1956, syn. nov.). The Hylicellidae is still poorly defined as is its generic composition. Mesothymbris, however, is clearly distinct from the other Mount Crosby hylicellids, Hylicella Evans, 1956, and Triassocotis, Evans, 1956, in the quite distal primary fork of R, the angled RA at the point of separation of RA1 with RA2 directed towards the apex of the tegmen, the upright RA1, the shape of the intra-medial cell, and CuA just distal to the basal cell strongly curved and very closely approximating the claval suture. The new synonymies further clarify the composition of the cicadomorphan fauna of the Mount Crosby Formation, which as a result of this and other recent revisions, now comprises 16 nominal species in the Dysmorphoptilidae, Hylicellidae and Mesojabloniidae, as well as three species incertae sedis. In the presence of Dysmorphoptilidae and Hylicellidae, the Mount Crosby cicadomorphan fauna is similar to that of the younger Late Triassic Blackstone Formation at nearby Denmark Hill and Dinmore. It differs significantly, however, in the absence, after 90 years of collecting of 100s of specimens, of any representatives of the Dunstaniidae, Mesogereonidae, or Tettigarctidae, families so characteristic of the Denmark Hill/Dinmore fauna. Whether this difference is biogeographical, ecological, or simply as a result of differential preservation is unknown.

The cephalopods from Union y Progreso represent the first fossil assemblage described from the Parras Shale in Coahuila, Mexico.Pseudoschloenbachia(Pseudoschloenbachia) aff.P. (P.)mexicana(Renz, 1936),P. (P.)mexicana(Renz, 1936),Baculites haresiReeside, 1927, andMenabites(Delawarella)vanuxemi(Morton, 1830) have a geographically restricted occurrence.Didymocerasjuv. sp.,Menuitesjuv. sp.,Polyptychocerasjuv. sp.,Pseudoxybeloceras(Parasolenoceras)juv. sp., andScaphitessp. ex gr.S. hippocrepis(DeKay, 1828) are represented by juveniles and could not be determined to species level.Desmophyllites diphylloides(Forbes, 1846) is the only long-ranging, cosmopolitan species described from this assemblage. Three new species are described:Eutrephoceras irritilasin. sp.,Hypophylloceras(Neophylloceras)arturoin. sp., andTetragonites silencioensisn. sp. The morphotypeBaculitesn. sp. is also inferred to be distinct. The faunal composition of this assemblage indicates a late early Campanian age. This assemblage shows a high degree of endemism. The causes for this endemism are currently unknown and difficult to assess. Nevertheless, the generic composition of the Union y Progreso ammonite assemblage suggests a short-term early Campanian endemic event.

Tertiary Period

The plant bug fauna of China is highly diverse and relatively poorly documented, with almost 900 currently known species, about a half of which had been revealed during the last two decades (Qi et al. 2003, 2007, Konstantinov & Namyatova 2008, 2009, Konstantinov et al. 2013). Future studies would almost certainly reveal many new species from the region. However, the present day distributions of Chinese plant bugs apparently reflect significant climate change since the Tertiary Period, and are largely influenced by influx of species from other regions. Particularly, the plant bug fauna of the Northwestern China is most similar to the faunas of Central Asia and Mongolia, having almost identical generic composition and sharing many common species (Kerzhner & Josifov 1999). This paper provides seven new synonymies of Miridae originally known from Central Asia and Mongolia and recently described as new from the Northern China.

First Time

The taxonomic richness of the marine Nematoda in coastal habitats of Brazil and similarities in generic composition among them are analysed. A complete faunal list is presented, containing 11 orders, 59 families, 294 genera and 231 species, among which 1 family, 10 genera and 87 species were discovered for the first time in Brazil. Seven habitats were considered (sandy beaches, estuaries, phytal, oceanic islands, beach rocks, salt works and artificial substrates): sandy beaches had the greatest generic richness (241), followed by estuaries (142) and the phytal environment (126). Taxonomic composition was similar to that of other coastal habitats sampled worldwide, with Chromadoridae and Xyalidae the most representative families. The three major habitats (beaches, rocky shores and estuaries), showed statistically significant differences in faunas. Estuaries were the most uniform in composition.
