A Revision of the American Spiders of the Genus Drassyllus (Araneae, Gnaphosidae)


Book Description

"The genus Drasyllus is redefined to include those gnaphosids with a preening comb on metatarsi III and IV, closely spaced posterior median eyes, and a medially situated, bifid terminal apophysis on the male palp, and is hypothesized to be the sister group of Camillina. The 59 known American species, found from southern Canada to Mexico, are placed in eight species groups. Keys, disgnoses, descriptions, illustrations, scanning electron micrographs, locality records, and distribution maps are provided. Zelotes mexicanus (Banks) is transferred to Drasyllus. Drasyllus novus (Banks) and D. dromeus Chamberlin are removed from the synonymy of D. frigidus (Banks) and D. orgilus Chamberlin, respectively, and considered valid. Fourteen specific names are newly synonymized: D. zelotoides (Worley) and D. moronius (Chamberlin), both with D. lamprus (Chamberlin); D. finium Chamberlin and D. dentelifer Chamberlin, both with texamans Chamberlin; D. sporadicus Muma with D. dixinus Chamberlin; D. virginianus Chamberlin with D. novus (Banks); D. ostegae Chamberlin with D. aprilinus (Banks); D. lutzi Chamberlin and D. devexus Chamberlin, both with D. dromeus Chamberlin; D. monicus Chamberlin with D. proclesis Chamberlin; D. lasalus Chamberlin and Gertsch and D. hubbelli Chamberlin and Gertsch, both with D. mexicanus (Banks); and D. mephisto Chamberlin and D. coahuilanus Gertsch and Davis, both with D. lepidus (Banks). The males of D. eremitus Chamberlin, D. nannellus Chamberlin and Gertsch, D. seminolus Chamberlin and Gertsch, D. lamprus (Chamberlin), D. louisianus Chamberlin, D. orgilus Chamberlin, D. arizonensis (Banks), D. saphes Chamberlin, and D. fractus Chamberlin, and the females of D. socius Chamberlin, D. inanus Chamberlin and Gertsch, D. eremophilus Chamberlin and Gertsch, D. ellipes Chamberlin and Gertsch, and D. prosaphes Chamberlin are described for the first time. Twenty-three new species are described from the southern United States and Mexico"--P. [3].




A Revision of the American Spiders of the Genus Zelotes (Araneae, Gnaphosidae)


Book Description

"The genus Zelotes is redefined to include those gnaphosids with a preening comb on metatarsi III and IV and an intercalary sclerite situated prolaterally between the tegulum and terminal apophysis on the male palp. The 58 known American species, found from Alaska and northern Canada to southern Mexico and Jamaica, are placed in three species groups with 13 subgroups. Cladograms, keys, diagnoses, descriptions, illustrations, scanning electron micrographs, locality records, and distribution maps are provided. The American species Z. fratris is removed from the synonymy of the European Z. subterraneus (C.L. Koch), but three other European species (Z. kodaensis Miller and Buchar, Z. pallidus (O.P.-Cambridge), and Z. nilicola (O.P.-Cambridge)) are newly recorded from America. Apparently introduced populations of the southwestern species Z. reformans Chamberlin are newly recorded from Peru and Hawaii. Eleven specific names are newly synonymized: Z. pallidenotatus Mello-Leitão with Eilica modesta Keyserling; Z. chicano Gertsch and Riechert with Z. lasalanus Chamberlin; Z. inheritus Kaston with Z. pullus (Bryant); Z. pullatus fox with Z. tuobus Chamberlin; Z. calvanisticus Chamberlin and Z. protestans Chamberlin, both with Z. monachus Chamberlin; Z. omissus Chamberlin with Z. perditus Chamberlin; Z. montereus Chamberlin with Z. discens Chamberlin; Z. nannus Chamberlin and Gertsch with Z. nannodes Chamberlin; Z. kodaensis Miller and Buchar with Z. puritanus Chamberlin; and Z. circumspectus (Simon) with Z. pallidus (O.P.-Cambridge). The males of Z. gynethus Chamberlin, Z. discens Chamberlin, Z. mayanus Chamberlin and Ivie, Z. monodens Chamberlin, and Z. reformans Chamberlin, and the females of Z. pullus (Bryant), Z. pseustes Chamberlin, Z. anglo Gertsch and Riechert, Z. petrophilus Chamberlin, and Z. nilicola (O.P.-Cambridge) are described for the first time. Thirty new species are described"--P. 99.







Field Guide to the Spiders of California and the Pacific Coast States


Book Description

"A user-friendly guide to identifying and understanding the spiders of the Pacific Coast. There are 67 families of spiders found in North America, and 59 of them can be found in California. This field guide will cover all 59 of those families, including introduced species and common garden spiders--those will be given extra coverage. Each family is reviewed including details of their identification, taxonomy, distribution, and natural history. There will be a full color plate for each of the families."--
