"August 28, 2009."
Includes bibliographical references (p. 12).A new genus and species, Iraponia scutata, are established for the first members of the Caponiidae to be found in Iran. Males of this new genus, the second known from Asia, are unique in the family in having an extensive ventral abdominal scutum, and in having lost the posterior median pair of spinnerets. These caponiids have six eyes, a character shared only with some members of the New World genus Caponina.Published by the American Museum of Natural History, New york, NY
Brignolia.
131 p. : ill. ; 26 cm.
"Issued April 29, 2011."Males of the goblin spider genus Brignolia Dumitresco and Georgesco have palps that are heavily sclerotized, resembling those found in males of the genus Ischnothyreus Simon. Nevertheless, these palps have the dorsal depression ("fenestra") previously considered synapomorphic for the genus Opopaea Simon (plus its likely synonym Epectris Simon), and the female genitalia also correspond closely to those of Opopaea species, with the addition of a posterior tube. Brignolia males lack the inflated and subbasally connected palpal patella characteristic of Opopaea (plus Epectris), and Brignolia is therefore hypothesized to represent the sister group of those taxa. The generic names Lisna Saaristo and Aridella Saaristo, each based on a single species from the Seychelle Islands, are newly synonymized with Brignolia. The type species, B. cubana Dumitresco and Georgesco, has attained a pantropical distribution, and has at least three earlier names; Xestaspis parumpunctata Simon from Sierra Leone, Gamasomorpha perplexa Bryant from the Virgin Islands, and B. recondita (Chickering) from Panama are each placed as senior synonyms of B. cubana. Opopaea ambigua Simon, from Sri Lanka, is transferred to Brignolia. A total of 26 new species are described. Two are from the New World (B. dasysterna from Florida, and B. cobre from Florida and the West Indies), but most are from southern Asia and the Indopacific region: B. sinharaja and B. ratnapura from Sri Lanka, B. rothorum, B. cardamom, B. kumily, B. valparai, B. kaikatty, B. nilgiri, B. kodaik, B. jog, and B. karnataka from southern India, B. bengal, B. sukna, B. assam, and B. ankhu from northern India and Nepal, B. mapha, B. suthep, B. diablo, and B. chumphae from Thailand, B. schwendingeri from Vietnam, B. palawan from the Philippines, and B. gading, B. elongata, and B. kapit from Borneo
Pelicinus.
43 p. : ill. (some col.) ; 26 cm.Although Pelicinus Simon and its type species P. marmoratus Simon were initially described from Saint Vincent in the Lesser Antilles, we hypothesize that Pelicinus is primarily an Old World genus, occurring natively in both southern Asia and Australasia. The type species has attained an anomalously pantropical distribution, and has been described at least eight times, in at least seven different genera; all those synonyms were based on island populations. Myrmopopaea jacobsoni Reimoser from Sumatra, Gamasomorpha minima Berland from the Phoenix Islands, Triaeris pusillus (Bryant) from the Virgin Islands, Scaphiella ula Suman from Hawaii, and P. mahei (Benoit) from the Seychelles are newly synonymized with P. marmoratus, and the species is newly recorded from the Bahama Islands, Brazil, Kenya, and the Marshall Islands. Myrmopopaea Reimoser and Harryoonops Makhan and Ezzatpanah are placed as junior synonyms of Pelicinus. The bulk of the species-level diversity of Pelicinus occurs in Australia. Here we treat only those members of the genus that occur outside that continent; 16 new species are described from Iran (P. sengleti), India (P. lachivala, P. madurai), Thailand (P. deelemanae, P. schwendingeri, P. sayam, P. khao), Laos (P. tham), Vietnam (P. duong), Malaysia (P. penang, P. johor), the Solomon Islands (P. churchillae), Fiji (P. raveni), and New Caledonia (P. monteithi, P. damieu, P. koghis)

Spiders (Araneae) from Swiss hothouses, with records of four species new for Switzerland
Investigations of invertebrates in nine hothouses (tropical gardens) in Switzerland provided some spiders as by-catch. In total, we collected 136 spiders, of which 65 specimens represent 14 species from six families (the rest of the collection consisted of unidentifiable juveniles). Nine species are alien for Europe, one originates from the Mediterranean and four species are native to Central Europe. Four species represent first records for the Swiss fauna: Nesticidae: Nesticella mogera (Yaginuma, 1972), Oonopidae: Diblemma donisthorpei O. , Ischnothyreus peltifer (Simon, 1892) and Prida sechellensis (). These four species are discussed briefly and documented with photos
The goblin spider genus Ischnothyreus (Araneae, Oonopidae) in the New World. (American Museum novitates, no. 3759)
32 p. : ill. (some col.) ; 26 cm. Part of the oonopid PBI project. Cf. acknowledgments.Although originally described from St. Vincent in the Lesser Antilles, the goblin spider genus Ischnothyreus Simon appears to be an Old World taxon that is represented in the New World only by two presumably introduced, pantropical, synanthropic species: I. peltifer (Simon) and I. velox Jackson. Two specific names based on New World specimens (I. barrowsi Chamberlin and Ivie from Florida, and I. indressus Chickering from the Lesser Antilles) are placed as junior synonyms of I. velox, which is newly recorded from Mexico, Panama, Jamaica, Hispaniola, Venezuela, Brazil, Madagascar, the Philippines, the Marshall Islands, Hawaii, the Marquesas Islands, and New Caledonia. A third species, I. browni Chickering, that is supposedly from Costa Rica was apparently based on mislabeled specimens that are actually from the Philippines. The type specimens of I. browni resemble those of the Seychelle species Ischnothyrella jivani (Benoit) in that the dorsal abdominal scutum of males is extremely weak and that of females is either greatly reduced or entirely lost. Both species nevertheless share the synapomorphies of Ischnothyreus, and the generic name Ischnothyrella Saaristo is therefore placed as a junior synonym of Ischnothyreus
The new Southeast Asian goblin spider genus Aposphragisma (Araneae, Oonopidae): diversity and phylogeny
The new genus Aposphragisma (Araneae, Oonopidae, Oonopinae) comprising the new species A. baltenspergerae, A. borgulai, A. brunomanseri, A. confluens, A. dayak, A. dentatum, A. draconigenum, A. hausammannae, A. helvetiorum, A. kolleri, A. menzi, A. monoceros, A. nocturnum, A. retifer, A. rimba, A. salewskii, A. scimitar, A. sepilok and A. stannum is described. It is characterised by very hard bodied, strongly sclerotized species with completely armoured prosoma and strongly sclerotized ventral and dorsal abdominal scuta. Aposphragisma gen. nov. is placed within the Gamasomorpha-group sensu Saaristo (2001). Descriptions and illustrations are given for all new species. A phylogenetic analysis based on 40 characters using Prethopalpus fosuma, Gamasomorpha asterobothros, G. cataphracta, G. seximpressa, Xestaspis biflocci, X. kandy and X. paulina as outgroup-taxa and Cortestina thaleri (Oonopidae, Sulsulinae) as the root is presented and discussed. Furthermore it is shown that females of Aposphragisma gen. nov. possess complex internal genitalia. The members of the new genus are ground-dwelling litter inhabitants restricted to Southeast Asian lowland and montane forests, with more than 60% of the species only known from single localities. They are presumed to be negatively affected by the massive destruction of pristine forest habitats within their range. This work has been conducted within the framework of the Planetary Biodiversity Inventory (PBI) of Oonopidae (see http://research.amnh.org/oonopidae)
