Lernanthropus cynoscicola sp.n. (Copepoda: Lernanthropidae), a parasite of sciaenid fish Cynoscion striatus Cuvier from the coast of Argentina, is described and illustrated. The new species resembles five other species of Lernanthropus in general body shape, but it can be distinguished from them by the relatively short and tapered dorsal plate of the 4th leg-bearing segment, the length of the 4th legs being approximately equal to the rest of the body, and other differences. L. trachuri Brian, 1903 is reported for the first time in Argentina on Trachurus lathami from the coast of the Buenos Aires province.
The present paper comprises a systematic survey of the chigger mites (Acarina: Leeuwenhoekiidae) collected from bats and bat guano in Cuban caves in 1965-1985. Wagenaaria similis is recorded for the first time in Cuba. The first hosts known for Ischnothrombium diploctenum are noted. Antrohoekia inexpectala, g.n., sp. n., a parasite of bats, is described.
We describe the course of events during the evolution of the 300 keV, 3B/M7 June 26, 1983, 14:07 UT flare, as observed at the Crimean Astrophysical Observatory. We show directly as they developed a/ preflare microprominence uprise (Fig. 1)
b/ emisslve-surge flare onset c/ flaring arch system during the maximum flare phase (Fig. 2) d/ flaring arch cooling, which dlffers from the proper "post-flare loops" phenomenon (Fig. 3). The maximum rate of the upward surge’s extension, along its
axis, was 360 km s-1.
