Two New Species

Recent efforts have been taken to survey and describe the ascidian fauna of the Pacific and Atlantic coasts of Panama; however, the genus Pyura still remains poorly known. Sampling events have been occurring since 2003. In this research, we describe two new species from the Atlantic coast of Panama: P. longispina sp. nov., P. lopezlegentilae sp. nov., and two new species from the Pacific Coast of Panama: P. carmanae sp. nov. and P. imesa sp. nov. We also supply a tabular key for all the Pyura species found in Panama.

Intertidal Fish

Microcotyle is one of the most diverse and controversial genera within the family Microcotylidae. To date, 131 species have been described in Microcotyle; however, more than half have been transferred to other genera, and several others have poor descriptions. Therefore, less than half of all Microcotyle species may be considered valid. In Chile, two species have been recognized, and unidentified Microcotyle have been found on several littoral fish, but there has been no effort to properly identify them. In this study, two new species of Microcotyle are taxonomically described from intertidal fish of the central (33°S) and south-central (36°S) regions of Chile. In this study, Microcotyle sprostonae n. sp. (collected mainly from Scartichthys viridis in central Chile) and M. chilensis n. sp. (collected mainly from Calliclinus geniguttatus in south-central Chile) were identified based on morphological and molecular analyses (ITS2 and 18S genes). Both species of Microcotyle principally differed from one another and from other valid species in the number of testes and clamps. The two new species also differed from one another by one base pair in the ITS2 and 18S genes and differed from other species of Microcotyle by several base pairs of both genes. Intertidal fish are mostly endemic to the Pacific coast of South America, and they have a limited geographical distribution that does not overlap with the type hosts of other Microcotyle species. Therefore, the two new species described here are distinguished from other congeneric species by morphological, genetic, and biological characteristics.

Pacific Species

The genus Platyrhina from the northwestern Pacific was reviewed, including a redescription and neotype proposal for Platyrhina sinensis (Bloch and Schneider 1801), and the description of two new species. Platyrhina limboonkengi Tang 1933 is relegated to the synonymy of P. sinensis, both species having two rows of hooked thorns on the mid-dorsum of the tail. Specimens previously widely identified as P. sinensis, but characterized by one row of such hooked thorns, represented an undescribed species, herein named Platyrhina tangi Iwatsuki, Zhang and Nakaya sp. nov. Platyrhina hyugaensis Iwatsuki, Miyamoto and Nakaya sp. nov., known from specimens limited primarily to the Hyuga Nada Sea, off Miyazaki, the Pacific coast of southern Japan, is similar to P. tangi in having one row of hooked thorns on the mid-dorsum of the trunk and tail, but differs in having larger hooked thorns, not encircled by light yellow or white pigment on the orbital, nape and scapular regions, and a pair of hooked thorns (absent in P. tangi) anteriorly on the scapular region. Nominal species are discussed and key to northwestern Pacific species of Platyrhina is provided.

Two new species of hydroids, Halopteris enersis sp.nov. and Halopteris schucherti sp.nov., from the Pacific coast of southern Chile are described and figured. Measurements and nematocyst data are provided for each species. Their morphological features are compared with those of other members of the genus, and comparative tables listing their peculiarities are presented.

Two New Species

Two new species of the actiniid genus Epiactis, Epiactis lisbethae and Epiactis fernaldi, are described from the intertidal zone of the San Juan Islands, Washington, U.S.A. The sea anemone genus Cnidopus is synonymized with Epiactis, and its type species, C. ritteri, is restored to the genus in which it was originally described. Thus, four species of Epiactis are known on the Pacific coast of North America: external brooders E. prolifera (type species of the genus) and E. lisbethae, which differ in sexuality and brooding periodicity; and internal brooders E. ritteri and E. fernaldi, which differ in cnidae, sexuality, and histology. These bring the number of nominal species in the genus Epiactis to 19.
