We describe Bythaelurus giddingsi sp. nov. based on 7 specimens collected using the submersible Johnson Sea-Link fromdeepwater (428–562 m depth) areas of the Galápagos Islands. It is presumed to be endemic to the archipelago. The newspecies differs from its congeners in its coloration, the length of its anal-fin base, and in other morphological characters. The disjunct distribution of species of the widely-distributed Indo-Pacific genus Bythaelurus is discussed.

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.

AbstractThe endemic Galápagos’ genus Neoryctes Arrow has had a confused nomenclatorial and taxonomic history. Evaluation of morphological variation in the 41 specimens now available confirms the distinctiveness of the genus and establishes the existence of four species, each restricted to a single island. The original Darwin specimen, named Oryctes galapagoensis by G.R. Waterhouse in 1845, is shown to be from Isla Santiago. Two other names are valid: N. linelli Mutchler for the population on San Cristobal and N. moreti Dechambre for the one on Santa Cruz. The population on Floreana is named as a new species, N. williamsi. Neoryctes most likely originated from a Pentodontini dynastine ancestor from lowland South or Central America. The ancestor first dispersed to Isla San Cristobal, one of the oldest islands. It is hypothesized that before hindwing reduction occurred, which is now characteristic of all members of the genus, individuals from San Cristobal spread to the other islands. Subsequently, possibly during periods of Pleistocene aridity, each population became restricted to its present range in the moist highland zone of an individual island.
