Type Specimens and identity of the described species of Conus II. The species described by Solander, Chemnitz, Born, and Lightfoot between 1766 and 1786

Twenty-three species of Conus were described by authors other than Linnaeus between 1766 and 1786. Of these, 3 are Eocene species from England described by Solander in Brander (1766), and the remainder are Recent. Chemnitz (1777) described one valid species. Of the 10 species described by Born (1778), 7 are valid, 2 are junior synonyms of Linnaean species, and 1 is a nomen dubium. Solander in [Lightfoot] (1786) described 5 species, of which 3 are valid and 2 are junior synonyms of Linnaean species. Lightfoot (1786) described 4 species, of which 1 is valid and 3 are junior synonyms of Linnaean species.
Holotypes of 7 species and lectotypes of 3 species exist, and representatives of lecto-types of 10 species have been selected. All of these types are illustrated photographically.
Between 1758 and 1786, 60 species of Conus were described, of which 45 are now considered valid. Of these, 42 are Recent.     

Ephemeroptera from Central and South America: New Species of the Farrodes bimaculatus Group with a Key for the Males

The genus Farrodes was recently revised, and two species groups were delimited: Farrodes caribbianus and Farrodes bimaculatus. In that paper the species of the F. caribbianus species group were described or redescribed. In the F. bimaculatus species group eight undescribed species were treated but not described. In the present paper, these new species of the F. bimaculatus species group are described and discussed and a key for the separation of all the species known from male imagines in this group is provided.     

Some American Austrolimnius (Coleoptera: Elmidae)

A key is given to the North American species of Austrolimnius, one of which is described as new. A new species from Venezuela is described, and new locality records in North and South America are listed for previously described species.     

Tropical fungus-feeding Thysanoptera of the genus Macrophthalmo thrips

The genus Macrophthalmothrips is redefined from a study of all the described species. One new species is described from Jamaica, five species are placed in synonymy, and a key is provided to the thirteen species now recognised. Variation in colour and antennal structure is discussed, and notes are given on the biology and distribution of the species.     

New species of Septobasidium from southern Costa Rica and the southeastern United States

New species are described in Septobasidium, a genus of urediniomycete parasites on scale insects. One new species, S. gomezii, is described from Costa Rica, and another, S. meredithiae, is described from Louisiana. S. gomezii is most similar to S. septobasidioides, but macroscopic and microscopic differences support it being a distinct species. S. meredithiae is similar to S. alni and S. castaneum but differs from these species in several macroscopic and microscopic characters, especially when the species are observed on the same host tree and insect species. Another species collected only once in Costa Rica is listed with observations but it is not formally described here. This Septobasidium species shares some key characteristics with S. ramorum but combines a dense, compact, nearly black thallus and pigmented probasidia-like structures with spindle-shaped haustoria. Implications for taxonomy, morphological evolution and host specificity in Septobasidium are discussed.     

First record of Balcha Walker (Hymenoptera,Eupelmidae) in South Korea with the description of one new species

The genus Balcha Walker (Eupelmidae) is recorded for the first time in South Korea, with one newly described species and one newly recorded species. Both sexes of Balcha opaca Fusu sp. n. are described, and the presumed male of B. dictyota Gibson is described for the first time. The newly described species is peculiar in having a comparatively darker and less shiny mesoscutum. In other species of the genus the mesoscutum has brilliant metallic colours that contrast with dorsal dark bands along areas of much finer sculpture.
