The leaf-mining agromyzid flies collected from the Republic of El Salvadorand the Republic of Guatemala and preserved in the California Academy of Sciences, San Francisco, were examined. Of the 22 species in eight genera that were identified, seven are new to science: Ophiomyia gracilimentula, Agromyza megaepistoma, Japanagromyza nebulifera, Calycomyza parallela, and Liriomyza pectinimentula from El Salvador, and Melanagromyza dolabrata and Phytobia guatemalensis from Guatemala. The remainder, except for Japanagromyza arnaudi Sasakawa, 1963, are new to the El Salvadoror Guatemala fauna. The species originally described as Agromyza approximata Frost, 1936 is transferred to Japanagromyza.
The Okinawan terrestrial crab Geothelphusa tenuimanus is redescribed and its intraspecific variation is discussed. The geographically isolated Tamagusuku (=southern) population tends to have a more laterally-directed curvature of the anterolateral margins of the carapace and relatively shorter fourth ambulatory legs. However, these differences are not very significant and the diagnostic male first gonopod shows no differences. Therefore, all the populations on Okinawa Island are here regarded as conspecific. Habitats and morphological adaptations of the species are also discussed.
A new species of mysidacean crustacean, Orientomysis calida, is described from the Gulf of Thailand. Orientomysis calida resembles O. leptura (Liu and Wang, 1980) but differs in that the second endopodal segment of the maxilla lacks tiny spines on the lateral margin, the exopod of the fourth male pleopod has two subequal terminal setae, and the uropodal endopod has a single spine on the ventral statocyst region. This is the first record of a species of Orientomysis outside East Asian waters.
Two new cypridinid ostracods, Skogsbergia abei and Paravargula maculosa, are described based upon specimens collected from shallow bottom sands using a baited trap at Shimoda, Izu Peninsula. This is the first record of these genera from Japan.
A new genus, three new species, and three known species of oribatid mite are described from the marine littoral of the Ryukyu Archipelago, southwestern Japan. These taxa are Arotrobates granulatus Luxton, 1992, Rhizophobates shimojanai gen. nov. and sp. nov., Schusteria nagisa sp. nov., S. saxea sp. nov., Alismobates reticulatus Luxton, 1992, and Fortuynia rotunda Marshall and Pugh, 2002. Two African species of the genus Schusteria, S. melanomerus Marshall and Pugh, 2000 and S. ugraseni Marshall and Pugh,2000, are transferred to the new genus Rhizophobates.
