New and rare Schizomida (Arachnida: Hubbardiidae) from South America

One new genus and eight new species of Schizomida are described from South America: Adisomus duckei n.g., n.sp. from Brazil, Rowlandius sul n.sp. from Brazil, Surazomus arboreus n.sp. from Brazil, S. manaus n.sp. from Brazil, S. mirim n.sp. from Brazil, and S. rodriguesi n.sp. from Brazil; Hansenochrus guyanensis n.sp. from Guyana; and Surazomus boliviensis n.sp. from Bolivia. New records of Surazomus brasiliensis (KRAUS) are included and the female genitalia are illustrated

Re-description of Togwoteeus biceps (Arachnida, Opiliones, Sclerosomatidae) with notes on its morphology, karyology and phenology.

The harvestman genus Togwoteeus Roewer 1952 is monotypic. Its only species, T. biceps (Thorell 1877), is known from throughout western Canada and USA and is newly recorded from California, Nebraska, Nevada, Oregon, South Dakota, and Utah. This species occurs below 500 m and at the highest elevation (4100 m) of any recorded harvestman in North America. It ranges from about 33-54° N and exhibits considerable variation in its morphological measurements. Twenty-seven such measurements are summarized for 80 males and 74 females. Ultrastructural details of the integument, appendages and genital organs are presented. The karyotype is 2n = 22 for both sexes. All chromosomes are metacentric and obvious sex chromosomes were not detected. Immature T. biceps overwinter and reach adulthood in late spring or early summer. Adults die by late fall

Schizomida/Zwerggeißelskorpione (Arachnida): eingeschleppt nach Europa - ein Aufruf

Jüngst (2004 bis 2006) wurden noch zu bestimmende Schizomiden in zwei Gewächshäusern in Deutschland gefunden. Da derartige Fälle sehr selten zu sein scheinen, möchten wir solche Meldungen zusammentragen und bitten hiermit um Literaturhinweise und Vermittlung/Zusendung von eventuell weiteren vorhandenen Exemplaren

A new Schizomus from the Indian state of Maharashtra, with additional comments on eyed Schizomids (Arachnida: Schizomidae)

A new species of Schizomus is described from the Indian state of Maharashtra. It is the fourth described schizomid to possess convex ocelli. New information is given regarding some old records attributed to S. cambridgei (Thorell), species inquirenda. The female spermathecae of S. bagnallii (Jackson) and S. biocellatus Sissom are described and illustrated, and other characters of the two species are discussed

Redescription of Schizomus crassicaudatus (Pickard-Cambridge) and Diagnoses of Hubbardia cook, Stenochrus chamberlin, and Sotanostenochrus new genus, with Description of a New Species of Hubbardia from California (Arachnida: Schizomida: Hubbardiidae)

Schizomus crassicaudatus from Sri Lanka is redescribed from the type series, and lectotypes of Nyctalops crassicaudata and N. Tenuicaudata are designed. Hubbardia Cook, previously considered a synonym of Schizomus Cook, is considered valid and rediagnosed to include species from California and Arizona. The family Hubbardiidae Cook has priority and therefore is used rather than Schizomidae Hansen and Sorensen. Additional descriptive notes and records are provided and a lectotypes is designated for Hubbardia pentapeltis Cook. Hubbardia idria new species is described from San Benito County, California. Additional records are included for H. briggsi. A key for identification of males of Hubbardia is presented. The native (introduced elsewhere) North and Central American genus Stenochrus Chamberlin is rediagnosed for most species of the Schizomus mexicanus, pecki, and goodnightorum groups. Sotanostenochrus, new genus, is described for Schizomus mitchelli Rowland, and Schizomus cookei Rowland and is known only from caves in San Luis Potosi and Tamaulipas, Mexico.Texas Memorial Museu

The occurrence of ecto-parasitic Leptus sp. mites on Africanised honey bees

Honey bee-mite-pathogen associations have led to the widespread collapse of Apis mellifera colonies in various parts of the world. The global trade in bees continues to expose honey bees to new pests and pathogens. Here we highlight to the beekeeping community a potential new mite-pathogen association. In South America ecto-parasitic Leptus mite larvae have been recorded parasitising adult honey bees and these mites are known to transmit Spiroplasma bacteria the causative agent of 'Mays disease' in bees. Here we provide new data and review past studies on Leptus mites and discuss the potential risk to A. mellifera this mite may pose in the future

First record of invasive Stenochrus portoricensis Chamberlin, 1922 (Arachnida: Schizomida: Hubbardiidae) from the Southern region of Brazil

Herein we report for the first time a schizomid for the Southern region of Brazil, Stenochrus portoricensis Chamberlin, 1922 (Schizomida: Hubbardiidae), found in association with termite nests. This is the southernmost record of any schizomid for the Neotropical region. We hypothesize that the species was recently introduced by the sudden population growth of Florianópolis – along with the intense touristic activity – which might have contributed to the inadvertent transportation of this species

Overview of Arachnids and Arachnology in Iran

An overview of the Arachnida and their study in Iran is provided. Besides ancient poetry, relics (going back to 5,000 YBP), and early medical observations (at least 2,000 YBP), the first published taxonomical observations of arachnids from Iran were in 1807 about scorpions. The superorders Parasitiformes and Acariformes (mites and ticks) have received by far the most attention among all of the Arachnida thanks to their economic and medical/veterinary importance. Occurrences have been noted for over 1,733 species in four orders: Ixodida, Mesostigmata, Sarcoptiformes, and Trombidiformes. The first tick of the Ixodida was described in 1818. The first mite species described from Iran was of the Mesostigmata in 1982. The first member of the Sarcoptiformes named from Iran is uncertain, but the first Iranian species of the Suborder Oribatida was described in 1984 and was likely the first for the order. The first species described from Iran of the Order Trombidiformes were named in 1995. Studies on spiders started in 1874. Spiders are recorded by the occurrences of 764 species. Scorpions number 68 species in Iran and receive a lot of study and are better known compared to mites and spiders on a percentage basis, because scorpions have such a small diversity worldwide. The first Iranian species of Solifugae was described in 1895. The camel spiders are known from 67 species. Pseudoscorpions are recorded by 65 species. The Opiliones are known by 22 named species. The Amblypygi are recorded from Iran by one species described in 2018. </p
