A reappraisal is presented of the taxonomy of three of the four alternate-leaved species of Chrysosplenium occurring in North America, namely C. tetrandrum, C. iowense, and C. Rosendahlii, the latter a new species described for the first time. The investigation demonstrates that the species can be readily separated morphologically even as seedlings. Each morphological entity is characterized by a different chromosome number, C. tetrandrum 2n = 24, C. Rosendahlii 2n = 96. C. iowense 2n = c.120, and a distinctive geographical distribution. C. iowense, which has on occasions been regarded as identical with C. alternifolium var. sibiricum, is retained as a species in the absence of a modern taxonomic analysis of the Old World species C. alternifolium.

The mirine plant bug genus Neolygus Knight is reported from Nepal and North India for the first time, thus representing the first confident distributional record of this genus from the Himalayas. A new species, Neolygus machanensis, is described from Nepal. Two known members, N. bui Lu & Zheng and N. keltoni (Lu & Zheng), newly recognized as occurring in Nepal and/or North India, are diagnosed. Habitus images of live individuals and illustrations of the male genitalia are provided for all treated species. A checklist of the Old World species, and discussion of the systematic position and zoogeography of Neolygus are included. Neolygus partitus (Walker, 1873) [Capsus], N. mjohjangsanicus (Josifov, 1992) [Lygocoris], and Neolygus zebei (Günther, 1997) [Lygocoris] are proposed as new combinations.

Centaurea sanandajensis is described and illustrated as a new species from Kurdestan Province, W Iran. The characters that distinguish the new species from its nearest relative C. longipedunculata are given. In addition, C. elegantissima is reported as new to Iran, and its chromosome number (2n = 2x = 22) is counted for the first time. The description of C. elegantissima is completed with the characters of mature achenes, and its differences from the nearest relative C. kandavanensis are summarized. The geographical distribution of discussed species is presented.

Abstract The description of a new species of an erymid lobster, Stenodactylina beardi, from the Upper Cretaceous Haslam Formation of the Nanaimo Group on Vancouver Island, British Columbia, Canada, brings to fifteen the number of Erymidae in North America. The species are arrayed within five genera based upon configuration of carapace groove morphology, resulting in two new combinations, Stenodactylina bordenensis (Copeland, 1960) and S. foersteri (Feldmann, 1979). The new species exhibits for the first time a male pleopod and accessory structures within Erymoidea. We also provide a list of the North American species of Erymoidea.

Since the publication of the previous paper (Leeson, 1953), additional information has been accumulated on the geographical distribution of some of the Old World ticks of the genus Ornithodoros and two new species (zumpti and arenicolous) have been described. Much of this additional matter has been communicated to me by correspondents who have been kind enough to give permission for its publication here. Their names are enclosed in brackets after the new data to indicate the source and to these workers I tender my sincere thanks.

A new species, Pholis clemensi, referred to the family Pholidae, is named and described from 12 specimens taken in southern British Columbia waters and the Strait of Juan de Fuca. Pholis clemensi is compared with other members of the genus, and a key is given to the North American species.

A remarkable new species, Odonteus gandhara Carpaneto & Mignani, n. sp., is described from northern Pakistan. The holotype (adult male) and the paratype (adult female) are illustrated and compared with O. armiger (Scopoli, 1772) and O. orientalis Mittal, 1998, the only two species of this genus recognized in the Old World. Both O. armiger and O. orientalis have the eye not completely divided by the canthus and have a sensory area on the external side of the last antennomere (this character has never been discussed in the literature until now). These two character states in O. armiger and O. orientalis compel emendations to the definition of the genus. The new species has a great zoogeographical relevance because similar species occur in North America (O. obesus LeConte, 1859 and O. falli Wallis, 1928), and probably represents a relict species endemic to the Himalayan range.

We describe a new species of Gomesa (Oncidiinae, Orchidaceae), Gomesa caatingana, with restricted distribution on caatinga inselbergs in Paraíba and Pernambuco States, Brazil. Morphological and karyological characters of the new species were compared with those of Gomesa flexuosa, which is morphologically the most closely related species. Differences in geographical distribution, habit, flower morphology and chromosome number support description of this new species.

We discuss seven species of tortricid moths that are leafminers at least in early instars. These include Grapholita thermopsidis Eiseman & Austin, new species, which feeds on Thermopsis rhombifolia (Pursh) Richardson (Fabaceae), along with two others for which larval hosts were previously unknown: Catastega triangulana Brown (Ericaceae: Arctostaphylos pungens Kunth) and Sparganothis xanthoides (Walker) (Polemoniaceae: Phlox divaricata L.). Parasitoids of G. thermopsidis include Dolichogenidea sp. (Hymenoptera: Braconidae) and Zagrammosoma mirum Girault (Hymenoptera: Eulophidae). The female genitalia of Epinotia nigralbana (Walsingham), a species that mines leaves of Arctostaphylos throughout larval development, are illustrated for the first time. Rhopobota finitimana (Heinrich), which feeds on Ilex spp. (Aquifoliaceae), is confirmed to mine leaves as has been documented previously in R. dietziana (Kearfott). Talponia plummeriana (Busck), which is known to feed in the developing ovaries of pawpaw (Annonaceae: Asimina spp.), also feeds in leaves before boring in the twigs and stems. Cenopis lamberti (Franclemont), previously reported from Persea sp. (Lauraceae), was reared from Symplocos tinctoria (L.) L’Hér. (Symplocaceae). Apart from the two exceptions noted above, all of these species exit their mines in later instars to feed in leaf shelters.

All macropterous species of Aptilotus Mik are keyed, with descriptions of two new macropterous North American species, Aptilotus pogophallus and A. nigriphallus. New distributional records are given for other North American species, and brachyptery is noted for the first time in A. luctuosus (Spuler). Four new macropterous species of Aptilotus (glabrifrons, spinistylus, rufiscapus, and binotatus are described from Nepal. The relationships between the North American and Nepalese species are discussed. Minocellina Papp is synonomized with Aptilotus, and the two species formerly in Minocellina, A. thaii (Papp) and A. besucheti (Papp), are thus given as new combinations. Limosina carbonicolor Richards, from Ethiopia, is redescribed and transferred to Aptilotus.
