Two new species of Iridoteuthis (Cephalopoda: Sepiolidae: Heteroteuthinae) from the southwest Pacific, with a redescription of Stoloteuthis maoria (Dell, 1959)

Examination of the Stoloteuthis maoria (Dell, 1959) type specimens held in the Museum of New Zealand, Te Papa Tongarewa revealed that the two female paratypes were not conspecific with the S. maoria holotype male and belong to the genus Iridoteuthis Naef, 1912. Based on this finding, Stoloteuthis maoria is redescribed here to properly define the male and female characters. Its occurrence in Australian waters is formally recognised for the first time; the species was known previously only from New Zealand. The Iridoteuthis taxon was found to be new and is described as I. merlini, n. sp. Like S. maoria, this new species occurs in New Zealand and southern Australia. A second new Iridoteuthis from New Zealand was also discovered among the Te Papa collection and is described here as I. lophia, n. sp. The sucker pedicels in males of this latter species are highly and uniquely modified.

Description of a new species of Platyparadonus Etzler and Ivie, 2019 (Coleoptera: Elateridae), with an updated key to species

A new species of the genus Platyparadonus Etzler & Ivie, 2019, is described from St. John (United States Virgin Islands). Taxonomic and diagnostic remarks are provided along with a map of distribution and a key to the species. The misinterpretation of female paratypes belonging to P. marleyi Etzler & Ivie, 2019 from St. John is also clarified.

Anopheles (Kerteszia) lepidotus (Diptera: Culicidae), not the malaria vector we thought it was: Revised male and female morphology; larva, pupa, and male genitalia characters; and molecular verification

The name Anopheles (Kerteszia) lepidotus Zavortink, commonly used for an important malaria vector in the eastern cor-dillera of the Andes, is here corrected to An. pholidotus Zavortink. We discovered that An. (Ker.) specimens from Peru,and reared-associated specimens from Ecuador, had unambiguous habitus characters that matched those on the male ho-lotype of An. lepidotus. However, the specimens do not exhibit characters of the female allotype and female paratypes ofAn. lepidotus, which are actually An. pholidotus. Our specimens are the first correctly associated females of An. lepidotus,which allow us to provide a new morphological interpretation for the adult habitus of this species. This finding is alsocorroborated by molecular data from a portion of the Cytochrome Oxidase I (COI) gene and ribosomal DNA Internal Tran-scribed Spacer 2 (rDNA ITS2). The pupal stage of An. lepidotus is described for the first time, and additional larval char-acters are also noted. Diagnostic morphological characters for the adult, pupal, and larval stages of An. pholidotus areprovided to separate the two species. All stages of An. lepidotus are easily separated from other currently known speciesin subgenus Kerteszia and a new key to the females of An. (Kerteszia) is given. Previously published distribution, bionomics, and medical significance data are corrected and enhanced.

A new species of Axiopsis (Axiopsis) (Thalassinidea, Axiidae) from the Pacific coast of Colombia

Axiopsis (Axiopsis) baronai is a new species of Thalassinidea (family Axiidae) from the Pacific coast of Colombia in depths of 5–9 m with soft mud substrate. A male holotype and three female paratypes are deposited in the Smithsonian Institution, Washington. D.C. Compared with other species of the genus it is large, reaching 94 mm total length (35 mm cl (measurement from the orbit to the posterior edge of the carapace in the midline dorsally)) in six specimens examined. It resembles A. (A.) consabrina but major differences include the similarity in size of first chelae. more spines on carinae of gastric region and only two or three spines laterally on the telson.

ON SOME NEARCTIC SPECIES OF AGABUS, WITH THE DESCRIPTION OF A NEW SPECIES. (COLEOPTERA: DYTISCIDAE)

The possibility of the above synonymy was suggested in a letter from Mr. W. J. Brown of Ottawa. Through the kindness of Dr. K. G. Blair and Mr. J. Balfour-Browne of the British Museum, I have been able to study a male and a female of A. elongatus (Gyllenhal), and to compare them with two male and two female paratypes of A. bryanti Carr.
