Four species of mole crickets (Orthoptera: Gryllotalpidae) are known from the West Indies: Neocurtilla hexadactyla (Perty), Scapteriscus abbreviatus Scudder, S. didactylus (Latreille), and S. imitatus Nickle and Castner. All are adventive (not native). We document their distributions in West Indian islands/countries by use of records from the literature and examination of specimens. Scapteriscus abbreviatus has been suggested to have arrived in, and been transported about the West Indies in ship ballast (immigration). Based on records of arrival in various parts of the West Indies and the species’ inability to fly, this suggestion seems reasonable. Scapteriscus imitatus pparently was released in Puerto Rico as a result of mistaken identification (introduction – arriving with assistance from humans – although inadvertent), and has not expanded its range in the West Indies. Although the principal mode of dispersal for the other two species also has been suggested to be ship ballast, we present an alternative based on flight which would seem at least equally as plausible. We suggest that S. didactylus could have dispersed by flight from South America through the Lesser Antilles; likewise N. hexadactyla probably from the Yucatan Peninsula to Cuba, and from South America northward through the Lesser Antilles, in at least some localities assisted by wind. Our zoogeographical alternative, if correct, means that the natural range expansions of these latter two species began very long ago and without human assistance – they were not introduced recently to the West Indies.
A newly discovered population of Xystocheir brachymacris Shelley, 1996 (Polydesmida: Xystodesmidae: Xystocheirini), in Placer County (Co.), California, exhibits an unusual grayish-black color dorsally with mottled, ovoid patches at paranotal bases; it cons titutes northern generic and specifi c range extensions of ~28.4 km (17.6 mi). The gonopods differ from those in the El Dorado Co. population in having shorter/acuminate prefemoral processes and blade-like, rather than spatulate, processes “B” that angle away from the solenomere instead of overhanging it. Additionally, a strong distomedial prefemoral lobe, absent from the El Dorado population, arises from the stem in Placer Co. males. Authorship of Xystocheirini is properly attributed to Hoffman, 1980.
Pinnaspis chamaecyparidis Takagi, Pinnaspis hikosana Takagi and Pinnaspis uniloba (Kuwana), occurring on Chamaecyparis obtusa Endl., Styrax japonica S. et Z. and Cleyera japonica Thunb. are newly documented in the Korean fauna of armored scales (Diaspididae). The characters of these species are here redescribed with illustrative photographs and information on distribution and hosts along with a dichotomous key to the species of Pinnaspis for correct species identifi cation. In addition, the paper discusses the current status of Pinnaspis buxi (Bouché) and Pinnaspis strachani (Cooley) which are known as native armored scale insects of Korea by analyzing information on the result of the survey.
The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. It comprises a total of 1191 species, distributed among 3 superclasses, 4 classes, 42 orders, 212 families and 617 genera. If considering only the EEZ and present territorial waters, this list represents an increase of 230 species (27.8%) and of 238 species (29.0%), when compared to the information available in FishBase (2012) and in the last checklist of marine and estuarine fishes of Portugal (1993), respectively. The order Perciformes shows the highest diversity, with 54 families, 162 genera and 299 species. Stomiidae (80 species), Myctophidae (71 species) and Macrouridae (37 species) are the richest families. From the listed species, 734 are present off mainland Portugal, 857 off the Azores and 766 off Madeira. Within the limits of the examined area, three species are reported for the first time in mainland Portugal and twenty-nine records are identified as doubtful. A total of 133 species have been recorded from the extended Portuguese continental shelf (2 off mainland Portugal, 117 off the Azores and 14 off Madeira), two of which are common to the Azores and Madeira extensions. Biogeographically, the Atlantic group is the most important (548 species – 46.01%), followed by the Lusitanian group (256 species – 21.49%), the African group (71 species – 5.96%), the Boreal group (34 species – 2.85%), the Mediterranean group (31 species – 2.60%), the Macaronesian group (21 species – 1.76%), the Atlantic/African group (19 species – 1.60%) and the Mediterranean/African and the Arctic groups, each with only 1 species (0.08%). Regarding the preferences for vertical habitat, the demersal fishes are the most important group (305 species – 25.61%), followed by the mesopelagic group (228 species – 19.14%), the bathypelagic group (164 species – 13.77%), the benthopelagic group (147 species – 12.34%), the bathydemersal group (115 species – 9.66%), the reef-associated group (88 species – 7.39%), the pelagic group (74 species – 6.21%), the epipelagic group (58 species – 4.87%) and 1 species (0.08%) of the benthic group. The oceanic habitat is the best represented group comprising 446 species (37.45%), followed by the shelf group (199 species – 16.71%), the slope group (164 species – 13.77%), the inner shelf group (89 species – 7.47%), the coastal group (70 species – 5.88%), the outer shelf group (29 species – 2.43%) and the oceanic/shelf group (7 species – 0.59%).
Tynommatidae, n. stat., elevated from Tynommatinae, is established as a schizopetalidean family encompassing the western North American callipodidans previously assigned to the Mediterranean Schizopetalidae. It is considered a valid taxon despite somewhat anatomically dissimilar subfamilies, and Colactidinae, Texophoninae, Diactidinae, and Aspidiophoninae constitute tribal elevations and additional new statuses. With a subbasal telopodal prefemoral process, Diactis hedini, n. sp., requires rediagnoses of all three diactidine genera, Diactis Loomis, 1937, and Florea and Caliactis, both by Shelley, 1996, and suggests that telopodal branches ‘B’ in congeners and Florea represent distal relocations of the process along the stem. Similarities in the sizes and shapes of the pleurotergal carinae suggest a sister-group relationship with the other, and partly sympatric, New World family, Abacionidae, which is supported by gonopodal similarities between Colactidinae and Abacion Rafi nesque, 1820. The Western Interior Seaway of the Cretaceous Period, Mesozoic Era, ~141–66 million years ago, appears to have fueled divergence by isolating “proto-abacionid stock” in “Appalachia,” the Eastern North American land mass, which has subsequently spread well into previously inundated areas. The allopatric position of Texophoninae, on the Gulf Coast of south Texas around 1,136 km (710 mi) east of the most proximate familial records, is attributed to this waterway, which eradicated faunal linkages with “proto-Tynommatidae” in “Laramidia,” the Western North American land mass. Texophoninae probably survived the Cretaceous on insular refugia; however, it is rarely encountered anymore and seems destined for imminent extinction. Representatives of the east-Asian families, Caspiopetalidae, Paracortinidae, and Sinocallipodidae, also possess demarcated pleurotergal crests and, implausible though it seems, may share ancestry with the North American taxa vis-à-vis the “Asiamerica” and or “Boreotropic” concepts.
Examination of the type series of Schizotus gibbifrons Lewis 1887 and Pyrochroa higoniae Lewis 1895, together with examination of the historical Lewis collection of Pseudopyrochroa japonica (Heyden 1879), provide hints as to the conspecifi city of these binomials. This evidence, together with concurrent collection events spanning more than 100 years and general anatomy suggests Pseudopyrochroa japonica (Heyden 1879) and Pseudopyrochroa gibbifrons (Lewis 1887) are conspecifi c. Schizotus gibbifrons Lewis is proposed as a new junior synonym of Pyrochroa japonica Heyden, where it joins the established synonym, Pyrochroa higoniae Lewis (1895). Schizotus theresae Pic 1911 is also proposed as a new junior synonym of Pyrochroa basalis Pic 1906, where it joins a long list of synonyms. Complete synonymies are presented for both species.
Two new species of pselaphine staphylinids in the genus Batrisodes are described: B. (Declivodes) dorothae Ferro and Carlton from Feliciana Preserve, Louisiana; and B. (Babnormodes) spretoides Ferro and Carlton from Great Smoky Mountains National Park, Tennessee. They differ from all other described Batrisodes species in secondary male characters, especially details of the frontal region of the head. These two species bring the total diversity of the genus in North America to 88 species. Specimens were imaged using light microscopy, scanning electron microscopy, and X-ray microtomography (micro-CT) techniques. Utility of multiple imaging techniques, especially micro-CT, is discussed.
Two new species and a new genus of Cerambycidae are described from South America: Cotyclytus arriagadai sp. nov., from Bolivia; and Lembu dieguezi, gen. nov., sp. nov., from Paraguay. Orthomegas irroratus (Lameere, 1915) is redescribed, based on the second and third known specimens, and its distribution is expanded to include Ecuador. The male of Jamesia fuscofasciata Dillon and Dillon, 1952 is described and illustrated for the fi rst time, and the distribution of the species is expanded to Peru. Thirty-two new country records (twelve for Paraguay, fi fteen for Peru, two for Ecuador, three for Bolivia) and one new province record (Argentina) are presented.
