[1].Item On the Chilean spiders of the family Prodidomidae (Araneae, Gnaphosoidea), with a revision of the genus Moreno Mello-Leitão. American Museum novitates ; no. 3499(New York, NY : American Museum of Natural History, 2005) Platnick, Norman I.; Shadab, Mohammad Umar.; Sorkin, Louis N.Although no members of the spider family Prodidomidae have previously been described from Chile, that country has a substantial, and largely endemic, prodidomid fauna. The Argentine genus Moreno Mello-Leitão is transferred from the Gnaphosidae to the Prodidomidae. Moreno was previously known only from the female holotype of its type species, but two additional species from Argentina and three from Chile are newly described, including the first known males of the genus. Three new genera are described: Chileomma, containing seven new six-eyed species from northern and central Chile; Chilongius, containing five new species from northern Chile; and Chileuma, containing three new species from northern and central Chile. A newly discovered feature on the tarsal claws is hypothesized to be a synapomorphy uniting Moreno and Chilongius with the other South American tricongiine Theuminae.Item A review of the pirate spiders (Aranae, Mimetidae) of Chile.

American Museum novitates ; no. 2672(New York, N.Y. : American Museum of Natural History, 1979) Platnick, Norman I.; Shadab, Mohammad Umar."Anapisona is redefined to include those anapids with a single distal apophysis on the male palpal femur, a dorsally elongated male palpal tibia, and distal bristles on the cymbium; and Pseudanapis those with a coarsely punctate carapace and sternum, a pattern of two apophyses on the male palpal femur, one or two on the patella, and none on the tibia, and subequally long legs I and IV. Keys, diagnoses, and supplementary illustrations are provided for the 10 known species of Anapisona, found from southern Mexico and the lesser Antilles south to Ecuador and Brazil, and the six known species of Pseudanapis, found in Indonesia, New Guinea, Melanesia, Hawaii, Middle and South America, and Central Africa. The suggested synonymy of Pseudanapis with Chasmocephalon is disclaimed, but of the 18 species previously assigned to Pseudanapis only P. aloha and P. wilsoni are congeneric with the type species, P. paroculus (the remainder being more closely related to Chasmocephalon); true Pseudanapis are newly recorded from America and Africa. Eight new species are described: A. kethlyi from Mexico and Costa Rica, A. ashmolei and A. pecki from Ecuador, A. bordeaux from the Virgin Islands, A. aragua from Venezuela and Colombia, A. schuhi from Brazil, P. benoiti from Zaire, and P. domingo from Ecuador.

American Museum novitates ; no. 2663(New York, N.Y. : American Museum of Natural History, 1978) Platnick, Norman I.; Shadab, Mohammad Umar."The presence of an anterior labral spur is suggested to be synapomorphic for the Anapidae. Anapis is redefined to include those anapids with a procurved posterior eye row, medially excavate chelicerae bearing a distal plate, a ridged palpal conductor, and a recurved retrolateral apophysis on the male palpal patella; at least some species build orb webs. The genera Epecthina Simon and Epechthinula Simon are newly synonymized with Anapis. A key, diagnoses, and supplementary illustrations are provided for the 21 known species, found from southern Mexico and Jamaica south to Peru and Brazil. Because more than half the species are known only from one sex, males and females were subjected to separate cladistic analyses; despite the availability of only an extremely small sample of characters, the resulting cladograms are compatible. A technique developed to combine their information generated eight specific predictions about the morphology of unknown specimens that can serve as tests of the hypothesized relationships. Fifteen new species are described: A. heredia and A. monteverde from Costa Rica, A. anchicaya, A. saladito, A. calima, A. digua, A. felidia, A. atuncela, A. guasca, A. meta, and A. amazonas from Colombia, A. choroni from Venezuela, A. chiriboga from Ecuador, and A. castilla and A. caluga from Peru.

The male of the Cuban species C. elegans is described for the first time and the species is newly recorded from Florida, many Caribbean islands, Hawaii, the Marshall Islands, and Angola. The female of the Brazilian species C. pulcher is newly described, and the species is recorded from Alabama; the males of C. pedestris and C. arguta (Simon) are also described for the first time. Twenty-nine new species are described"--P. [1].Item A revision of the American spiders of the genus Drassyllus (Araneae, Gnaphosidae). Bulletin of the AMNH ; v. 173, article 1([New York] : American Museum of Natural History, 1982) Platnick, Norman I.; Shadab, Mohammad Umar."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 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.

American Museum novitates ; no. 2560(New York, N.Y. : American Museum of Natural History, 1974) Platnick, Norman I.; Shadab, Mohammad Umar."The bispinosus and bicolor groups of Trachelas, and the 29 species from North and Central America and the West Indies placed in them, are diagnosed and described. In both groups the male embolus is not a separate sclerite but merely the pointed tip of the tegulum, and the lateral ducts of the internal female genitalia are generally not folded anteriorly. As defined, the bispinosus group includes those species in which the male endites have lateral spurs and the bicolor group those species in which the male endites lack spurs. Insular evolution in the bicolor group and the use of the scanning electron microscope in studying genitalia are discussed. Fourteen new species are described: prominens from Central America, trifidus from Panama; digitus and planus from Costa Rica; parallelus from Nicaragua; rotundus from Chiapas; dilatus and erectus from Hispaniola; tomaculus, oculus, contractus, and inclinatus from Cuba; giganteus from Jamaica; and triangulus from the Canal Zone.

On the basis of shared derived characters it is concluded that the Actinopodidae and Migidae are sister groups and that of the three known genera of Actinopodidae, Actinopus and Missulena together constitute the sister group of Neocteniza. The genitalia of Neocteniza, particularly of the male, are of extraordinary complexity for mygalomorph spiders, and suggest that males can mate only once and females only once during each adult instar. Five new species are described: N. pococki from Venezuela, N. fantastica from Colombia, N. osa from Costa Rica, N. subirana from Honduras, and N. paucispina from Guatemala. Genitalic and somatic characters of the group are illustrated in detail for the first time"--P. [1].Item A revision of the neotropical spider genus Apodrassodes (Araneae, Gnaphosidae).
