Squat Lobsters

Seven species of chirostyloidean squat lobsters are reported from the Galapagos Rift zone and Galapagos platform: Eumunida subsolanus n. sp. (Eumunididae), Heteroptychus galapagos n. sp., H. nautilus n. sp. (Chirostylidae), Uroptychus bellus Faxon, 1893, U. compressus n. sp., U. occidentalis Faxon, 1893 (Chirostylidae), and Sternostylus defensus (Benedict, 1902) (Sternostylidae). All new species are described and illustrated, and the two species previously known from the Galapagos Islands, Uroptychus bellus and U. occidentalis, are re-illustrated from respective lectotypes, herein designated, since both original descriptions were only brief. Both the species of Heteroptychus and Eumunida subsolanus are the first representatives of their respective genera in the eastern Pacific and the latter is also the first record for the family Eumunididae in the region.

A New Species

Coleophora darwini sp. nov., is described from the Galápagos Islands. This is the first record of the family Coleophoridae for the Galápagos. Adults were reared from larvae found mining leaves of Amaranthus andersonii Howell (Amaranthaceae) on Pinzón Island. Adults of the species also were collected at light on the islands of Española and Pinta. Coleophora darwini is similar to C. intexta Meyrick, 1917 from Peru. Adults, and male and female genitalia of both species, as well as the larval case of C. darwini, are illustrated and morphological characters distinguishing the two species are presented. A lectotype is formally designated for C. intexta.

Gulf Of Tehuantepec

In the Tropical Eastern Pacific region, the gammaridean amphipods of the families Maeridae and Melitidae are represented by 28 species and 11 genera; the genus Elasmopus is the richest, with 13 species. The examination of approximately 3,250 specimens resulted in 12 new records from the Gulf of Tehuantepec, belonging to four genera, Elasmopus, Maera, Quadrimaera and Melita. All species are illustrated and described. Seven new species are described as: Elasmopus bastidai n. sp., Elasmopus karlae n. sp., Elasmopus lecroyae n. sp., Elasmopus marcelae n. sp., Elasmopus oaxaquensis n. sp., Maera umarae n. sp., and Melita bousfieldi n. sp. With these new species the genus Elasmopus from the Tropical Eastern Pacific is increased to 18 species that corroborates the hypothesis of Barnard (1979) “on the Pacific there are (sic) a mark of speciation of genus Elasmopus”. In addition, there are five new records from the Gulf of Tehuantepec: three species of Elasmopus and two of Quadrimaera. Also, the range distribution of Elasmopus temori Barnard and E. zoanthidea Barnard, is increased to the north from the Galapagos Islands to the Gulf of Tehuantepec; for E. tubar Barnard, Quadrimaera chinarra Barnard, and Q. reishi Barnard, there are new intermediate records between the Gulf of California and the Galapagos Islands. With the exception of the species of Quadrimaera, all known species represent the second record in the region after their first descriptions.

A New Species

The small, monogeneric family of polychaetes known as Trochochaetidae has been exclusively collected in the northern hemisphere, mainly in temperate–cold environments. Nine species have been described so far including Trochochaeta mexicana sp. nov. described herein, while one species remains unnamed. Only two species had previously been recorded in the eastern Pacific, so T. mexicana sp. nov. is the first record for the family in the tropical Mexican Biogeographic Province. The new species is characterized by having a pair of eyes, acicular neurochaetae on chaetigers 2 and 3, a small knob-like antenna and a nuchal crest projecting through chaetiger 1. Trochochaeta mexicana sp. nov., together with Trochochaeta kirkegaardi, Trochochaeta diverapoda and Trochochaeta cirrifera are the only trochochaetids that have been found exclusively in warm environments.

Ptilocrinus atlanticus sp. nov. belongs to the family Hyocrinidae (Echinodermata, stalked Crinoidea). That new species is the first record of the genus Ptilocrinus in the Atlantic Ocean. Skeletal organization of the arms suggests that it has a taxonomic place halfway between the genus Ptilocrinus (especially Ptilocrinus pinnatus from N.-E. Pacific) and the genus Anachalypsicrinus, only recorded from N.-E. Atlantic. Such a discovery confirms the phylogenic affinities between large hyocrinids of the eastern Pacific and those of the northern Atlantic. Geographic isolation of these two deep-sea provinces since the Uppermost Cretaceous took place after the differentiation of the two genera Ptilocrinus and Anachalypsicrinus.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

Two New Species

This study presents the first records of the subfamily Lestremiinae and the genus Insulestremia Jaschhof in Brazil. Insulestremia, a previously monotypic genus described from the Galapagos Islands, has three species in Brazil: I. sinclairi Jaschhof, I. amorimi sp. nov. and I. amenti sp. nov. The new species are described, the generic concept is reviewed, and a key to the species of Insulestremia is provided.
