Currently, the genus Chimarra Stephens (Trichoptera: Philopotamidae) is represented in the Oriental Region by 259 species. Of these, 61 species have been described or recorded from Vietnam. In this paper, 9 new species from Vietnam are described and illustrated (Chimarra aculeata, C. carinata, C. corneola, C. insolita, C. mina, C. prominens, C. rostrata, C. undulata, and C. ungula). In addition, 3 new country records are noted (Chimarra areli Malicky and Mey, Chimarra pipake Malicky and Chantaramongkol, and Chimarra suthepensis Chantaramongkol and Malicky), and 1 new species group (minuta Group) is proposed and populated. An additional species group (georgensis “Group”), with 1 new species from Vietnam, but otherwise only known from Africa, is discussed, but not formally defined. A table listing all known Vietnamese species of Chimarra is included, along with discussion of variability in the anal veins of the forewing found within this genus, and its relevance for defining subgenera and species groups.
The diplopod orders Callipodida and Polydesmida, and their respective families Abacionidae and
Xystodesmidae, are initially recorded from South Dakota as is Polydesmidae from North Dakota. Other new records of
indigenous taxa include Abacion Rafinesque, 1820/A. texense (Loomis, 1937) and Pleuroloma/P. flavipes, both by
Rafinesque, 1820, from South Dakota, and Pseudopolydesmus Attems, 1898/P. serratus (Say, 1821) from Alabama,
Connecticut, Delaware, New Hampshire, North Dakota, South Carolina, and the District of Columbia. New records of
Aniulus garius Chamberlin, 1912, A. (Hakiulus) d. diversifrons (Wood, 1867), and Oriulus venustus (Wood, 1864)
(Julida: Parajulidae) are provided for western Minnesota and/or eastern North Dakota. Published records from these
states are summarized, and the introduced taxa, Julidae/Cylindroiulus Verhoeff, 1894/C. caeruleocinctus (Wood, 1864)
and Paradoxosomatidae/Oxidus Cook, 1911/O. gracilis (C. L. Koch, 1847), are newly recorded from the Dakotas. The
distribution of P. serratus, which extends from Maine to South Carolina and the Florida panhandle, west to Texas, and
north to Fargo, North Dakota is described and discussed. This distribution exhibits a prominent southeastern lacuna
which we hypothesize suggests replacement by younger, more successful species, as postulated for a similar distributional
gap in Scytonotus granulatus (Say, 1821).
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.”
With the discovery of Mitocybe auriportae Cook and Loomis, 1928 (Platydesmida: Andrognathidae) in Alameda County (Co.), east of San Francisco Bay, a potential overall distribution in coastal California is projected based on those of partly congruent diplopods. The area extends from northern Mendocino to central Monterey cos. and inland to central Lake, Yolo, and Santa Clara cos.
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.
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.
We provide the first records of six species of biting midges (Diptera: Ceratopogonidae) in the genus
Culicoides Latreille from Mexico: C. baueri Hoffman, C. castillae Fox, C. debilipalpis Lutz, C. iriartei Fox, C. leoni
Barbosa and C. pusilloides Wirth and Blanton. In addition, C. leopoldoi Ortiz is confirmed from Mexico, and new
records are included for 25 other species previously recorded in Mexico: C. arubae Fox and Hoffman, C. blantoni Vargas
and Wirth, C. crepuscularis Malloch, C. daedalus Macfie, C. diabolicus Hoffman, C. foxi Ortiz, C. furens (Poey), C.
gabaldoni Ortiz, C. haematopotus Malloch, C. hylas Macfie, C. insignis Lutz, C. jamaicensis Edwards, C. luteovenus
Root and Hoffman, C. neopulicaris Wirth, C. nigrigenus Wirth and Blanton, C. pampoikilus Macfie, C. panamensis
Barbosa, C. paraensis (Goeldi), C. phlebotomus (Williston), C. poikilonotus Macfie, C. pusillus Lutz, C. stigmalis Wirth,
and all three species in the C. (Monoculicoides) variipennis complex, C. variipennis (Coquillett), C. occidentalis Wirth
and Jones, and C. sonorensis Wirth and Jones.
The mirine plant bug Tropidosteptes forestierae, new species (Hemiptera: Miridae) is described from
Collier County, Florida, where it was found causing serious injury to an extensive ornamental hedge of Florida swampprivet, Forestiera segregata (Jacq.) Krug and Urb. (Oleaceae). Adult male and female, fifth instar, and egg are described. Color images of the adults, nymph, egg, and injury; scanning photomicrographs of selected adult structures; and illustrations of male genitalia are provided. A key to help distinguish the 16 species of Tropidosteptes known to occur in the southeastern United States is given.
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.
