Jaqueline Y. Miller Deborah L. Matthews Andrew D. Warren M. Alma Solis Donald J. Harvey Patricia Gentili-Poole Robert Lehman Thomas C. Emmel Charles V. , Jr. Covell

A biodiversity inventory of the Lepidoptera of Pico Bonito National Park and vicinity, in the Department of Atlantida of northern Honduras, was initiated in 2009 to obtain baseline data. We present a revised checklist of Honduran butterfly species (updated from the initial 1967 lists), as well as the first comprehensive list of Honduran moths. Our updated list includes 550 species of Papilionoidea, 311 Hesperioidea, and 1,441 moth species.

The apterous endemic genus Omphra Dejean (Coleoptera: Carabidae: Helluonini) of the Indian subcontinent: taxonomy with notes on habits and distributional patterns (2012)

Shiju T. Raj Thomas K. Sabu Zhao Danyang

Among the four oriental genera of the tribe Helluonini, Omphra Dejean (Coleoptera: Carabidae), is unique for its endemism to the Indian subcontinent and aptery. High intraspecies variability in morphological characters and limited diagnostic information makes species differentiation of the genus Omphra a complicated task. The present study provides a description of a new species, Omphra drumonti n. sp. from the Western Ghats, redescriptions and a key to the species of Omphra, details of intraspecies variation, discussion of relationships between taxa and distributional patterns of the genus. Based on the distributional patterns in the Indian subcontinent and flightlessness of the genus, inability to cross the physical barrier of the Ganges–Brahmaputra delta between north and peninsular India is indicated as the reason for its absence in the northeastern Indian subcontinent and endemism to the lower Indian subcontinent.

The milliped genus Euryurus Koch, 1847 (Polydesmida: Euryuridae) west of the Mississippi River; occurrence of E. leachii (Gray, 1832) on Crowley’s Ridge, Arkansas (2012)

Rowland M. Shelley Chris T. McAllistor Henry W. Robinson

The milliped genus Euryurus Koch, 1847, and the species, E. leachii (Gray, 1832) (Polydesmida: Euryuridae), are recorded from three sites on the northern part of Crowley’s Ridge (Cross, Lee, and Poinsett counties), Arkansas, where the only prior familial records are of Auturus evides (Bollman, 1887). Coupled with the published locality of E. leachii in Phillips Co., at the southern extremity of the Ridge, the only known occurrences of both the genus and species in Arkansas and west of the Mississippi River are in this physiographic feature. The Arkansas population is geographically peripheral but anatomically intermediate between the two recognized subspecies, E. l. leachii and E. l. fraternus Hoffman, 1978, and we do not assign it to a race. Molecular investigations seem necessary to resolve relationships in the “E. leachii complex.”

Revision der in Europa vorkommenden Arten von Thalictrum subsectio Thalictrum (Ranunculaceae) (2001)

Ralf Hand

Nach den Ergebnissen einer Revision kommen in Europa sieben Arten von Thalictrum subsect. Thalictrum vor: Th. foetidum in der Nominatsippe (daneben eine weitere Subspecies in Ostasien), Th. minus mit sechs Subspecies (zwei weitere Unterarten außerhalb Europas), Th. simplex mit vier Subspecies (zwei weitere Unterarten außerhalb Europas), Th. flavum, Th. speciosissimum mit zwei Subspecies, Th. maritimum sowie Th. lucidum. Die lange Zeit akzeptierte Sippe Th. morisonii ist auch als Subspecies nicht aufrecht zu erhalten. Die Ergebnisse basieren auf Studien am natürlichen Standort der meisten Sippen, der Kultur mehrerer Hundert Pflanzen unter standardisierten Bedingungen sowie der Bearbeitung umfangreichen Herbarmaterials. Durch die Kombination dieser Methoden ließ sich die Variabilität anatomischer und morphologischer Merkmale dokumentieren. Es werden die Ergebnisse von 115 Chromosomenzählungen vorgestellt, die teils bisher bekannte Resultate bestätigen, teils neue Erkenntnisse darstellen, darunter etwa die Existenz von tetraploidem Th. minus auch in Europa, hexaploiden Populationen von Th. simplex und die erstmalige Dokumentation der Chromosomenzahl von Th. maritimum (tetraploid, 2n = 28). Bei Th. simplex deckt sich die morphologische Variabilität teilweise mit der cytologischen Differenzierung, nicht hingegen bei Th. minus. Die Untersuchung blühphänologischer Aspekte erwies sich zumindest bei Th. minus als hilfreich für die taxonomische Gliederung dieser Sippe. Die Bastardierung von Sippen konnte zum zweiten Mal cytologisch untermauert werden. Insgesamt zwingt die sehr große morphologische Plastizität der meisten Sippen in Verbindung mit der ausgeprägten Tendenz zur Bildung geringfügig differenzierter, erbkonstanter Lokalpopulationen zu der Anwendung eines weiten Art- und auch Unterartkonzepts. Bedingt durch die Merkmalsarmut der Subsektion Thalictrum sind die akzeptierten Sippen dennoch in einigen Fällen nur schwer zu trennen. Die Abgrenzung von Varietäten wird nicht für sinnvoll erachtet. Im Rahmen der Revision werden erstmals auch alle verfügbaren infraspezifischen Namen der untersuchten Taxa bis hinab zur Rangstufe der Varietät zusammengestellt (insgesamt rund 1300 Namen) und nomenklatorisch bewertet. Für viele strittige Namen soll durch Typisierung eine Stabilisierung erreicht werden. Aus den Resultaten lassen sich erste Schlüsse zur Phylogenie der Gruppe ziehen. Th. foetidum besitzt besonders durch die abweichende Fruchtstruktur eine Sonderstellung. Europa stellt für die Subsektion, deren Mannigfaltigkeitszentrum in Ostasien liegt, insofern ein sekundäres Entfaltungszentrum dar, als sich aus vornehmlich anemogamen Arten mehrere ausgeprägt entomophile Sippen entwickeln konnten. Da bisherige Konzepte der Gattungsgliederung nur bedingt die tatsächliche Phylogenie widerspiegeln dürften, ist eine endgültige Klärung darüber, ob Thalictrum subsect. Thalictrum monophyletisch ist, nur durch eine Revision aller altweltlichen Taxa zu erzielen.

Chalcosicya maya n. sp, a new Mexican species (Coleoptera: Chrysomelidae: Eumoplinae) and its implications for morphology and biogeography (2012)

R. Wills Flowers

Chalcosicya maya, new species, (Coleoptera: Chrysomelidae: Eumolpinae) is described and the species key of Blake (1951) is modified to accommodate it. This is the first known mainland species of this previously Antillean genus. Sclerotized rods in the apical segment of the ovipositor of Chalcosicya Blake and related genera are shown to be useful systematic characters within the eumolpine tribe Adoxini. Relationships with other genera suggest that Chalcosicya belongs to a clade derived from ancestors with a western Tethyian distribution.

Recognition of Chyrsobothris thoracica guadeloupensis Descarpentries, 1981 at the species level (Coleoptera: Buprestidae) (2012)

Norman E. Woddley Julien Touroult

Evidence is presented that the subspecies Chrysobothris thoracica guadeloupensis Descarpentries, 1981 (Coleoptera: Buprestidae) should be recognized at the species level. Character evidence is provided to separate C. guadeloupensis, new status, from C. thoracica Fabricius, 1798. Both species are illustrated with habitus photographs and images of the male genitalia.

A summary of the endemic beetle genera of the West Indies (Insecta: Coleoptera); bioindicators of the evolutionary richness of this Neotropical archipelago (2012)

Stewart B. Peck Daniel E. Perez-Gelabert

The Caribbean Islands (or the West Indies) are recognized as one of the leading global biodiversity hot spots. This is based on data on species, genus, and family diversity for vascular plants and non-marine vertebrates. This paper presents data on genus level endemicity for the most speciose (but less well publicised) group of terrestrial animals: the beetles, with 205 genera (in 25 families) now recognized as being endemic (restricted) to the West Indies. The predominant families with endemic genera are Cerambycidae (41), Chrysomelidae (28), Curculionidae (26), and Staphylinidae (25). This high level of beetle generic endemicity can be extrapolated to suggest that a total of about 700 genera of all insects could be endemic to the West Indies. This far surpasses the total of 269 endemic genera of all plants and non-marine vertebrates, and reinforces the biodiversity richness of the insect fauna of the West Indies.

Preliminary checklist of the Cerambycidae, Disteniidae, and Vesperidae (Coleoptera) of Peru (2012)

Miguel A. Monné Eugenio H. Nearns Sarah C. Carbonel Carril Ian P. Swift Marcela L. Monné

A preliminary checklist of the Cerambycidae, Disteniidae, and Vesperidae (Coleoptera) of Peru is presented. Within Cerambycidae, we record five subfamilies, 55 tribes, 345 genera and subgenera, and 714 species. Within Disteniidae, we record one tribe, six genera, and 11 species. We also record one subfamily, one tribe, one genus, and two species within Vesperidae. Four new country records are recorded: one species in the tribe Anacolini (Cerambycidae: Prioninae): Cycloprionus flavus Tippmann, 1953; and three species in the tribe Onciderini (Cerambycidae: Lamiinae): Cacostola simplex (Pascoe, 1859); Marensis simplex (Bates, 1865); Trachysomus cavigibba Martins, 1975. In addition, 161 species recorded are known only from Peru.
