The earliest known members of the Thais clade of rapanine muricid neogastropods comprise four species from the Cantaure Formation (early Miocene: Burdigalian) of Venezuela; three of these species are new. Neorapana rotundata Gibson-Smith et al., 1997, is most closely related to the Recent Pacific Mexican N. tuberculata (Sowerby, 1835), and represents the only known Atlantic occurrence of the genus. Thais brevicula new species is closest to T. callaoensis (Gray, 1828) from the Recent of northern Peru and the Galápagos. A review of the genus Thais indicates that the typical members of this group occur in the South Atlantic, West Africa, and eastern Pacific, but not in the Recent fauna of the southern Caribbean. Stramonita bifida new species is a large species related to the Recent S. haemastoma floridana (Conrad, 1837), which occurs throughout the Caribbean. A review of American species of Stramonita indicates that the taxon S. biserialis (de Blainville, 1832) from the Recent fauna of the eastern Pacific, and the taxon S. h. haemastoma (Linnaeus, 1767), may each be composed of more than one species despite the teleplanic dispersal of their larvae. Stramonita semiplicata new species is closely related to the Recent S. bicarinata (de Blainville, 1832) from the South Atlantic, and represents a lineage that occurred in the Caribbean region until at least the late Miocene. It may have given rise to the eastern Pacific genus Acanthais. The higher diversity and greater antipredatory specialization of eastern Pacific as compared to western Atlantic members of the Thais clade may have resulted from higher post-Miocene rates of speciation and lower extinction rates in the eastern Pacific.

Abstract A description is provided for Meliola trichostroma. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Meliola trichostroma parasitizes a cultivated plant very frequent in tropical America, but without the production of evident symptoms of any disease in the host. HOSTS: Psidium araca, P. guajava, P. guineense, P. pomiferum. GEOGRAPHICAL DISTRIBUTION: Brazil, British Guiana, Colombia, Costa Rica, Cuba, Ecuador, Honduras, Jamaica, Nicaragua, Panama, Paraguay, Puerto Rico, Dominican Republic, Surinam, Trinidad & Tobago, Venezuela. TRANSMISSION: By air-borne ascospores.

Dentalion gen. nov. (Hymenoptera: Eulophidae: Entedoninae), is described from the northern part of the Neotropical region, from Costa Rica to Ecuador and Brazil, and the Caribbean (Trinidad & Tobago). It comprises eleven new species: D. alveum, D. ambonatum, D. apertum, D. apon, D. crassicornis, D. jimenezi, D. mischum, D. noyesi, D. pinguicornis, D. pnigaliae, D. quadrifer. These species are diagnosed, described and illustrated, and a key for their identification is provided. Dentalion is characterized by two putative autapomorphies and two synapomorphies. The phylogenetic implications of these apomorphies are discussed briefly.

First Time

Cornugon gen. nov. (Hymenoptera: Eulophidae: Entedoninae) is described from the Neotropical region, including ten new species from Costa Rica, Ecuador, Honduras and Mexico: C. albicoxa, C. anais, C. bicornis, C. diabolos, C. diceros, C. gibberum, C. leios, C. petiolatum, C. reticulatum, and C. unicornis spp. nov. The monophyly of the genus is demonstrated through two putative morphological autapomorphies. One of the autapomorphies is in a recently discovered character system, wing interference colour patterns (WIPs). WIPs are used here for the first time at the generic level for the classification of insects. Cornugon is compared to Pediobius Walker with which it shares the most apomorphies.

A New Species

Gammaropsis elvirae sp. nov. is described and illustrated here, as a new species of the family Photidae Boeck, 1871, occurring on sites widely distributed in the soft-sediment habitats from the Yucatan shelf, southern Gulf of Mexico. This new species differs from all other congeners by a unique set of characteristics: lateral cephalic lobes rounded; outer lobes of lower lip with one cone on each lobe; gnathopod 1 propodus longer than carpus; gnathopod 2 propodus enlarged with small convoluted processes on posterior margin and palmar angle undefined; gnathopod 2 dactylus short, less than one half in length of propodus; dense setation on basis, carpus, and propodus of gnathopod 2; epimeral plates 1–3 rounded; inner ramus of uropods 1–3 longer than outer ramus; and telson emarginated. Ecological comments on spatial distribution and associated environmental variables are included, as well an identification key to the genus in tropical America.

A New Species

A new species, Stropharia acanthostipitata, is here described from the Dominican Republic and French Guiana based on morphological and molecular ITS/LSU analyses. It is distinguished by a dry, smooth and hygrophanous pileus with minute and fugacious velar remnants at the pileus margin, exannulate stipe, brown lamellae, presence of chrysocystidia on both edge and face of lamellae, and the occurrence of acanthocytes all over the stipe surface.
