Scorpions Of The Genus Diplocentrus (Diplocentridae) From Sonora, Mexico, With Description Of A New Species, W. David Sissom, Anne L. Wheeler

Insecta Mundi

To date, only two references place members of the genus Diplocentrus in Sonora, Mexico. The first was a passing comment by Francke (1975) that D. spitzeri Stahnke occurs in northeastern Sonora. The specimens he examined and used in his systematic studies on that species are the same as the ones reported here for the first time from a specific Sonoran locality. The second reference was by Sissom and Walker (1992) listing a single record of D. gertschi Sissom and Walker from Libertad on the northern coast.

Purification And Characterization Of A Midgut Lectin-Trypsin Complex From The Tsetse Fly Glossina Longipennis, E. O. Osir, L. Abubakar, M. O. Imbuga

All Peer-Reviewed Publications

A blood-meal-induced lectin (agglutinin) with proteolytic activity was isolated from midgut extracts of Glossina longipennis by a two-step procedure involving anion-exchange chromatography. It is a glycoprotein [native molecular weight (Mr, 61000±3000 da) composed of two noncovalently-linked subunits designated α (Mr, ∼27000 da) and β (Mr, ∼33000 da). The trypsin activity and the glycosyl residues were present on the α- and β-subunits, respectively. The native protein was capable of agglutinating both bloodstream-form and procyclic trypanosomes as well as rabbit red blood cells. This activity was strongly inhibited by D-glucosamine and weakly inhibited by N-acetyl-D-glucosamine. Similarly, soybean trypsin inhibitor abrogated agglutination of …

Properties Of A Blood-Meal-Induced Midgut Lectin From The Tsetse Fly Glossina Morsitans, L. Abubakar, E. O. Osir, M. O. Imbuga

All Peer-Reviewed Publications

The properties of a blood-meal-induced lectin (agglutinin) from the midgut of Glossina morsitans capable of agglutinating Trypanosoma brucei were studied in vitro. The midgut homogenate from flies that had been fed twice had the highest agglutination activity, followed by that from the once-fed flies and that from the unfed insects. As compared with the bloodstream-form trypanosomes, a much lower concentration of the midgut homogenate was required for agglutination of the procyclic parasites. Furthermore, the agglutination process was specifically inhibited by D-glucosamine. Soybean trypsin inhibitor abrogated agglutination of the bloodstreamform parasites, whereas the procyclics were unaffected. The agglutination process was temperature-sensitive, …

Book Review: Rare And Endangered Biota Of Florida, Volume Iv. Invertebrates., Ross H. Arnett Jr.

Insecta Mundi

Of all of the Florida invertebrates that exist, or may have existed (one estimate claims 50,000 species) only descriptions of 350 species are included in this book. These are species that are thought to be, according to the many individual authors who wrote the accounts of these species, in decline or in danger of extinction. Final acceptance to be included in this book, and others in the series, is made by the Florida Committee on Rare and Endangered Plants and Animals. They believe, as do the various authors and editors, that there is enough information available to show that these …

News And Views

Insecta Mundi

The Center for Systematic Entomology plans to publish four Newsletters each year, but these are usually not kept as permanent records by libraries. Therefore, some information is printed in Insecta Mundi concerning primary changes in our journal as well as matters of records concerning the CSE.

Requirements For Publication In Insecta Mundi

Insecta Mundi

The quarterly journal, Insecta Mundi, is among the very few journals that have no page charges. However, since the Center for Systematic Entomology is entirely financed through dues, subscriptions, and cash donations, we have certain requirements for publication in the journal. (See also information on front inside cover of the journal.)

Hydrellia Bicarina, N.Sp. (Diptera: Ephydridae), A Leafminer In Southern Watergrass, D. L. Deonier

Insecta Mundi

The species Hydrellia bicarina, n.sp. originally misidentified and described as Hydrellia spinicornis Cresson by Deonier (1971) is redescribed and illustrated. This species was first collectedon and reared from Southern Water Grass Luziola fluitans (Michaux) growing in shallow baytree swamps of southern Mississippi by Deonier (197 1). Based on the male and female genitalia and its natural history, this species is a member of the Hydrellia griseola species group.

North American Members Of The Hydrellia Crassipes Species Group (Diptera: Ephydridae), D. L. Deonier

Insecta Mundi

The known members of the Hydrellia crassipes species group in North America are described or redescribed, including H. crassipes Cresson, H. procteri Cresson, H. saltator Deonier, H. amplecta n.sp., H. bryani n.sp., H. ocalae n.sp., and H. tibiospica n.sp. Adults of these species exhibit the following synapomorphies: dilated male metafemur and expanded (and flange din some) male metatibia and striate (fibrillate) distiphallus. Only a single species (H. tibiospica n.sp.) was reared from its host-plant species, Juncus debilis Gray, but there are associated habitat data to indicate that the entire species group may have sedges andrushes as host plants.

A Report On A Collection Of Ceratopogonidae (Diptera) From Rondonia (Brazil) And Iquitos (Peru) 1. Tribes Palpomyiini And Stenoxenini, Andrea Dippolito, Gustavo R. Spinelli, Willis W. Wirth

Insecta Mundi

Examination of two large collections of Ceratopogonidae from Rondonia, Brazil, and Loreto, Peru, resulted in records of 15 species in the tribes Palpomyiini and Stenoxenini, including three previously undescribed: Bezzia schmitzorum Dippolito & Spinelli, Palpomyia pseudolacustris D. & S., and Stenoxenus aductus D. & S. from Rondonia. The hitherto unknown male of Palpomyia versicolor Macfie is described and figured.

Nueva Especie De Trientoma (Coleoptera: Tenebrionidae: Trientomini) Para Cuba Con Consideraciones Sobre Otras Especies, Orlando H. Garrido, Esteban Gutierrez

Insecta Mundi

Segun Marcuzzi (1984), hay seis especies de Trientoma en Las Antillas, pero olvidó incluir T. wickhami Casey de Las Bahamas. De esas siete especies, sólo una, se encontraba reportada para Cuba, T. varvasi Solier, 1835. Por lo tanto este género era muy poco conocido y con escasos especímenes depositados en colecciones.

Gundlach, en su colección actualmente depositada en el Instituto de Ecología y Sistemática de la Academia de Ciencias de Cuba, posee solamente tres ejemplares. Con el numero 1567 tiene a Trientoma sp., pero en realidad este ejemplar coincide con el género Trimytantron descrito por Ardoin en 1977. Con el …

Nueva Especie De Loxostethus (Coleoptera: Tenebrionidae: Diaperini) Para Cuba, Orlando H. Garrido, Esteban Gutierrez

Insecta Mundi

El género Loxostethus fue descrito por Triplehorn (1962), describiendo las especies fasciatus y opacifrons para Cuba, jamaicensis para Jamaica, y unicolor para Puerto Rico. Todas fueron halladas en hongos, y si bien no han sido reportadas de la Isla de Santo Domingo no es de extrañar que eventualmente aparezcan. Zayas (1989) describió L. quadrimaculata para Trinidad, Cuba-sin embargo, esta última especie cae dentro de la variación individual de L. fasciatus de acuerdo a la descripción de Triplehorn. Por consiguiente, L. quadrimaculata es sinonimizado bajo Loxostethus fasciatus. Gundlach tiene representado en su colección estos dos taxa bajo el género Cyphiscus …

Bibliography On Hydrellia Griseola Fallen (Diptera: Ephydridae) And Review Of Its Biology And Pest Status, Louis S. Hesler

Insecta Mundi

A bibliography is presented on Hydrellia griseola (FallBn), a cosmopolitan species of shore fly that is an agricultural pest throughout much of its range. The literature review includes 195 references and spans 180 years: from 1813, when H. griseola was first described (as Notophila griseola), to 1993. My review updates and extends by 110 years a previous review of this species. The host plant associations, bionomics, distribution, pest status, and control of this species are reviewed. The known host plants of larval H.griseola are listed. My survey of the literature supports the hypothesis that H. griseola is increasing its …

A Status Report On The Species Of Timarcha (Coleoptera: Chrysomelidae), Pierre Jolivet

Insecta Mundi

The species of Tirnarcha are unique living fossils among the leaf beetles. They walk very slowly, cannot escape by flight, and their majestic bearing can be compared to the Athenian judges, the Timarches. Unfortunately, they are vulnerable to habitat disturbance, insecticides, and environmental changes. Some of the European such as Timarcha tenebricosa and T. goettingensis are becoming more and more rare because of these same habitat changes.

New Locality Records For Bruchidae Of Florida And The West Indies (Coleoptera), John M. Kingsolver

Insecta Mundi

Recent collections have resulted in provisional extensions of distributional ranges of 4 species of Bruchidae. All species of plants listed belong to the Leguminosae (Fabaceae).

Acanthoscelides obvelatus Bridwell was recently intercepted at the Miami, Florida, International Airport infesting Phaseolus spp. beans grown in Haiti and Cuba. Previous records for this bruchid include mainland localities in Mexico, Guatemala, and Colombia. No precise localities in the West Indies are known. These collections indicate that this bruchid is probably established on Hispaniola and Cuba.

Two New Species Of Kermes (Homoptera: Coccinea: Kermesidae), With A Key To The Young Adult Females Of Known Species Of Kermes From China, Yongjie Liu, Yuliang Shi

Insecta Mundi

Two new species of Kermesidae, Kermes orientalis Liu and Shi and K. flavus Liu, are designated. Morphological characters of post-reproductive and teneral young adult females, as well as the first instars (crawlers) are described and illustrated. A key to the young adult females of the genus from China is given. Type materials are deposited in the Insect Collection, Section of Entomology, Department of Entomology, Shandong Agricultural University, Shandong; Insect Collection, Institute of zoology, Chinese Academy of sciences, Beijing, China; and British Museum (Natural History), London, England.
