What is Bolshecapnia sasquatchi Ricker? Plus a new species of Bolshecapnia from Montana (Plecoptera: Capniidae).
Richard W. Baumann and David S. Potter
Illiesia 2007 3(15):157-162 (12 November 2007)
ABSTRACT
The name Bolshecapnia sasquatchi was found to include 2 different species. The name bearing, original species, occurs in British Columbia and Washington and a previously undescribed species, B. missiona, occurs in Montana. Bolshecapnia sasquatchi was only known in the male adult stage, but the female is herein described. Bolshecapnia missiona is described in the male, female and larval stages. SEM photos of the male and female terminalia are given for both species and a diagnosis is provided that separates these 2 species in the male and female adult stages. Distribution records are given for both species.

Taiwanese species of Cryptoperla (Plecoptera: Peltoperlidae).
Bill P. Stark and Ignac Sivec
Illiesia 2007 3(14):150-156 (17 September 2007)
ABSTRACT
The Taiwanese species of Cryptoperla are reviewed and three species are given formal recognition. Records are given for Cryptoperla formosana (Okamoto), a previously recognized species and a new name, C. klapaleki is proposed for C. formosana (Klapálek). The latter species is redescribed from the holotype and from fresh material, and a new species C. uchidai is also proposed. Unassociated females for one species are described under an informal designation.

The Winter Stoneflies (Plecoptera: Capniidae) of Mississippi.
Tina M. Nations, Bill P. Stark and Matthew B. Hicks
Illiesia 2007 3(9):70-94 (20 August 2007)
ABSTRACT
The Mississippi winter stonefly fauna includes seven Allocapnia species [A. aurora Ricker, A. granulata (Claassen), A. mystica Frison, A. polemistis Ross & Ricker, A. rickeri Frison, A. starki Kondratieff & Kirchner and A. virginiana Frison] and Nemocapnia carolina Banks; Allocapnia recta (Claassen), previously recorded from the state, is deleted from the list and all records for this species are assigned to A. starki. The male epiproct and 8th tergal process of the Mississippi Capniidae were examined with scanning electron microscopy, and the female subgenital plates were also studied to determine if these could be reliably separated. A brief description is given for female genital segments of A. polemistis.

The life cycle and nymphal feeding of Capnioneura petitpierreae Aubert, 1961 (Plecoptera, Capniidae).
Daniel Navarro-Martínez, Manuel J. López-Rodríguez & J. Manuel Tierno de Figueroa
Illiesia 2007 3(8):65-69 (17 July 2007)
ABSTRACT
The life cycle and nymphal feeding of Capnioneura petitpierreae Aubert in a temporary stream in the Southern Iberian Peninsula was studied. This collector-gatherer species had a univoltine life cycle with fast growth. In fact, nymphs are only present during five months, from November to March, showing remarkable size variation in all months. The life cycle is compared with that of other Plecoptera from temporary streams and with other species of Capniidae.

Studies of Indonesian Perlidae (Plecoptera), with descriptions of three new species.
Bill P. Stark and Ignac Sivec
Illiesia 2007 3(7):53-64 (11 July 2007)
ABSTRACT
Records are presented for sixteen perlid stoneflies in Indonesia including three previously unrecognized species from Kalimantan. Most records are from the islands of Sumatra, Java or Borneo, but also included are records of Neoperla nymphs from Irian Jaya Province on the island of New Guinea. Tetropina larvata Klapálek is placed as a synonym of T. fulgescens (Enderlein) and egg descriptions based on scanning electron micrographs are provided for several species.

Cosumnoperla sequoia, a new species of stonefly from the Sierra Nevada, California (Plecoptera: Perlodidae: Isoperlinae).
Richard L. Bottorff
Illiesia 2007 3(6):46-52 (26 June 2007)
ABSTRACT
A new stonefly species, Cosumnoperla sequoia, is named from an intermittent stream in the southern Sierra Nevada, California. The adult male and female, mature larva, and egg are described, illustrated, and compared with Cosumnoperla hypocrena Szczytko and Bottorff. The adult males of C. sequoia most clearly differ from C. hypocrena by their unique 10th tergal process and swollen spinule patches on tergum 8 and 9. Adult females are distinguished by their elongated and shallowly notched subgenital plate, while larvae possess distinctive medial sclerites on ventral thoracic segments. Both species are apparently restricted to intermittent streams in the Sierra Nevada, California.

New species of and keys to South American Gripopterygidae (Plecoptera).
Ian D. McLellan and Peter Zwick
Illiesia 2007 3(4):20-42 (26 June 2007)
ABSTRACT
Uncicauda pirata new genus and species and Alfonsoperla flinti new genus and species are described. The larvae of the following named species are either described for the first time (1st) or corrected (cd) descriptions given: Antarctoperla altera (1st), Aubertoperla illiesi (cd), Aubertoperla kuscheli (cd), Claudioperla tigrina (cd), Limnoperla jaffueli (cd), Rhithroperla rossi (cd), Teutoperla spp. (1st). We also describe larvae of four Antarctoperlinae species that cannot be associated with adults; these new larvae are therefore not named. The larvae of the South American Gripopterygidae are keyed to genus, and some to species.

Phenology and diversity of adult stoneflies (Plecoptera) of a small coastal stream, California.
Richard L. Bottorff and Loren D. Bottorff
Illiesia 2007 3(1):1-9 (9 March 2007)
ABSTRACT
Collections of adult stoneflies over a full year at Irish Gulch Creek, Mendocino Co., California, revealed 23 species. Adults were present at all times of the year. Species number varied from an autumnal low of 2 to a spring peak of 13. Adults of most species were present for less than 3 months, but Malenka depressa adults were present year-round. Hesperoperla hoguei was the only strictly autumnal-emerging species. The report of Suwallia dubia from Irish Gulch Creek represents a new California record. The stonefly faunas of Irish Gulch Creek (low coastal) and Sagehen Creek (high Sierra Nevada) were compared. Both creeks had similar numbers of species, but the species composition differed greatly, reflecting dissimilar environments (elevation, water temperature, thermal accumulation, and discharge). Irish Gulch Creek had uniform warmer temperatures; Sagehen Creek had variable colder temperatures. Peak emergence at Irish Gulch Creek occurred 2 months earlier than at Sagehen Creek.
