Revisiting the Andean butterfly Eryphanis zolvizora group (Lepidoptera, Nymphalidae) : one or several species?

Eryphanis zolvizora (Hewitson, 1877) is a rare Andean endemic butterfly, described from Bolivia, which has been historically classified either as a unique species, or as part of a group of three allopatric species from Bolivia, Ecuador and Colombia. In this paper, the group is revised using more than 200 specimens housed in 35 European and North and South American public and private collections. For the first time, the presence of the group in Western Ecuador and Venezuela is confirmed, and important data on Peruvian populations are provided. In some populations, individual variations of genitalia are observed. Nevertheless, male genitalia allow the distinction of four geographical groups. Considering also habitus characters, eight taxa are distinguished and considered to be subspecies, of which five are new: Eryphanis zolvizora inca ssp. nov., Eryphanis zolvizora chachapoya ssp. nov., Eryphanis zolvizora casagrande ssp. nov., Eryphanis zolvizora reyi ssp. nov., and Eryphanis zolvizora isabelae ssp. nov. In the present state of knowledge, these taxa are allopatric, except for a possible geographic overlap in central Peru, where data are insufficient to prove sympatry. The “several subspecies vs. several species” dilemma is discussed, considering its impact for conservation action and policies

New Species of Sminthuridae from North America (Collembola: Symphypleona)

(excerpt) This account is the result of efforts by Drs. Kenneth Christiansen and Peter Bellinger to amass and examine the major collections of North American Collembola. Their work will culminate in a descriptive monograph on the Collembola-fauna of North America. The author agreed to describe part of the new species of Sminthuridae extracted from those collections. The analysis of specimens justifies erection of 17 species new to science

Description of a New Species of Slave-making Ant in the \u3ci\u3eFormica Sanguinea\u3c/i\u3e Group (Hymenoptera: Formicidae)

The new species, Formica gynocrates, is described and illustrated from all the castes. This slave-making species is a member of the sanguinea group and is most similar to F. pergandei. The type locality is the E. S. George Reserve, Livingston County, Michigan. Specimens were also examined from North Dakota, Wyoming, and Colorado. A key is provided for the separation of the described North American members of the sanguinea group. The most commonly associated slave species is F. vinculans Wheeler, a member of the neogagates group. It is our opinion that F. vinculans is a valid species and not a synonym of F. neogagates, as has been previously supposed

Perlodidae (Plecoptera) of Wisconsin

The family Perlodidae is one of the most abundant and widespread in the order Plecoptera. These stoneflies occur in a wide variety of clean-water habitats and as indicator organisms have potential for assessing water quality. Studies of this family in Wisconsin prior to 1965 were limited to occasional collections reported by Needham and Claassen (1925) and Frison (1935, 1937, 1942). In 1965 and 1966 a survey of the Wisconsin River and its tributaries yielded nymphs of 11 species of Isoperla (W. Hisenhoff, unpublished report), and later, nymphs and adults of 9 species were found in the Pine-Popple River (Hilsenhoff and Narf 1972). Between 1966 and 1971 additional Perlodidae were collected throughout the state by several persons, many of them by Arvin Krueger while surveying the mayfly fauna of Wisconsin (Krueger 1969)

Ichneumonid wasps from Madagascar. VI. The genus Pristomerus (Hymenoptera: Ichneumonidae: Cremastinae)

Pristomerus species of Madagascar are revised. We report 15 species, of which 12 are newly described: P. guinness sp. nov., P. hansoni sp. nov., P. kelikely sp. nov., P. keyka sp. nov., P. moramora sp. nov., P. melissa sp. nov., P. patator sp. nov., P. ranomafana sp. nov., P. roberti sp. nov., P. vahaza sp. nov., P. veloma sp. nov. and P. yago sp. nov. Pristomerus albescens (Morley) and P. cunctator Tosquinet are newly recorded from Madagascar and new host and/or distribution records are provided for this species. A dichotomous key to all species is provided. The zoogeographical relation of the Malagasy fauna of Pristomerus with respect to mainland Africa is discussed: only three of the 15 species are reported to occur outside of Madagascar, suggesting a high level of endemism in Madagascar which was not unexpected

Five new species of the genera Heerz Marsh, Lissopsius Marsh and Ondigus Braet, Barbalho and van Achterberg (Braconidae, Doryctinae) from the Chamela-Cuixmala biosphere reserve in Jalisco, Mexico

Five new species belonging to the poorly known Neotropical doryctine parasitoid wasps genera Heerz Marsh (H. ecmahla sp. n. and H. macrophthalma sp. n.), Lissopsius Marsh (L. pacificus sp. n. and L. jalisciensis sp. n.) and Ondigus Braet, Barbalho & van Achterberg (O. cuixmalensis sp. n.) are described from the Chamela-Cuixmala Biosphere reserve in Jalisco, Mexico. Keys to the described species of the above three genera are provided. The phylogenetic placement of the examined taxa is investigated based on mitochondrial (COI) and nuclear (28S, 2nd and 3rd domain regions) DNA sequence data.Fil: Zaldivar Riverón, Alejandro.

Limnological study of Zealand Pond, White Mountains, New Hampshire

Zealand Pond, New Hampshire, was chosen as the site of a remote lake study. Data were collected between July 18 and August 29,1997. Zealand Pond had a relatively high pH (6.3-6.9) and alkalinity (2.3- 3.1 mg CaCO3 /liter), considering its small size and elevation (752 m). The lake was not thermally stratified, presumably due to its shallow depth and exposure to wind. Zealand Pond had a diverse zooplankton community, with two calanoid copepod species (Hesperodiaptomus wilsonae and Leptodiaptomus ashlandi), two cyclopoid copepods (Mesocyclops edax and Ectocyclops phaleratus), six cladoceran species (Daphnia ambigua, Daphnia pulex, Ceriodaphnia reticulata, Bosmina longirostris, Alona costata, and Polyphemus pediculus), and two rotifer species (Keratella taurocephala and Conochilus sp.). Densities of zooplankton ranged from 57.6 (Hesperodiaptomus) to 0.04 (Alona) animals per liter. Zooplankton species were documented with photographs and key identifying features. Low densities of fish were also present in the lake. Features of Zealand Pond are compared to other high altitude lakes
