First record of the family Issidae (Hemiptera, Auchenorrhyncha: Fulgoroidea) from the Hawaiian Islands

Euroxenus vayssieresi (Bonfils, Attie & Reynaud, 2001) (Issinae, Sarimini) was described (in the genus Borbonissus Bonfils, Attie & Reynaud, 2001) from Réunion Island, in the Indian Ocean and previous to this report has not been recorded elsewhere. Euroxenus vayssieresi is here illustrated and redescribed to improved taxonomic diagnosis. Euroxenus vayssieresi is recorded for the first time from the island of Hawaii in the Hawaiian Archipelago. This is first record of the family Issidae from the Hawaiian Archipelago.

Better educational signage could reduce disturbance of resting dolphins

Spinner dolphins on Hawai‘i Island’s west coast (Stenella longirostris longirostris) rest by day in protected bays that are increasingly popular for recreation. Because more frequent interactions of people with these dolphins is likely to reduce rest for dolphins and to explain recent decline in dolphin abundance, the National Oceanic and Atmospheric Administration (NOAA) proposed stricter rules regarding interactions with spinner dolphins near the main Hawaiian Islands and plans to increase enforcement. Simultaneous investment in public education about both interaction rules and their biological rationale has been and is likely to be relatively low. To test the hypothesis that more educational signage will reduce human-generated disturbance of dolphins, a paper questionnaire was distributed to 351 land-based, mostly unguided visitors at three dolphin resting bays on Hawai‘i Island’s west coast. Responses indicated that visitors wanted to see dolphins, were ignorant of interaction rules, were likely to read signs explaining rules and their biological rationales, and were likely to follow known rules. Therefore, investment in effective educational signage at dolphin resting bays is recommended as one way to support conservation of spinner dolphins on Hawai‘i Island’s west coast and similar sites in the Hawaiian archipelago.

Bright Sunshine, Dark Shadows

Lindsay Wilhelm, “Bright Sunshine, Dark Shadows: Decadent Beauty and Victorian Views of Hawai‘i” (pp. 495–526) Inspired by the recent global turn in aestheticism and decadence studies, this essay considers how late-Victorian discourses surrounding beauty, pleasure, and morality inform contemporary literary representations of Hawai‘i as both supremely inviting and dangerously languorous. The essay begins with a short overview of the broader geopolitical and historical circumstances that helped shape nineteenth-century understandings of Hawai‘i—a place renowned abroad for its beauty and hospitality, but nonetheless still notorious as the site of James Cook’s death in 1779. Next, the essay traces the peculiar ambivalence with which travel memoirs such as Isabella Bird’s The Hawaiian Archipelago (1875) and Constance Gordon-Cumming’s Fire Fountains (1883) describe their authors’ experiences in the islands. In these memoirs, Hawai‘i evidences the same convergence between beauty and decay that undergirds the controversial aesthetics of Algernon Charles Swinburne, Oscar Wilde, and other adherents of the creed of “art for art’s sake.” Focusing particularly on Robert Louis Stevenson’s fairy tale “The Bottle Imp” (1891), the essay then examines the ways in which Victorian writers utilize Hawai‘i’s leprosy epidemic as an occasion for exploring the perils of aesthetic hedonism. The essay concludes by briefly turning to the work of nineteenth-century Hawaiian historian Samuel Kamakau, whose own depictions of the decaying Hawaiian village reveal, by contrast, how these British accounts enlist the language of decadence in the service of empire.

A taxonomic reassessment of the genus Sticta (lichenized Ascomycota: Peltigeraceae) in the Hawaiian archipelago

The taxonomy of the genus Sticta in Hawaii is reassessed, based on a separately published molecular phylogeny using the fungal barcoding marker ITS. Based on Magnusson and Zahlbruckner's treatment from 1943 and Magnusson's catalogue from 1955, seven species of Sticta and three infraspecific taxa had been reported from the archipelago, all widespread except the putative endemic S. plumbicolor. Here we provide a taxonomic treatment of 13 taxa, 12 species and one subspecies, distinguished in a previous phylogenetic analysis: S. acyphellata, S. andina, S. antoniana, S. emmanueliana, S. flynnii, S. fuliginosa, S. hawaiiensis, S. limbata, S. plumbicolor, S. scabrosa subsp. hawaiiensis, S. smithii, S. tomentosa and S. waikamoi. All taxa are described, discussed and illustrated and a dichotomous key is presented. The implications of revised species taxonomies for studies in other fields such as ecology, ecophysiology, biogeography, biochemistry, and applications such as environmental monitoring are discussed. We also propose a protocol to use Sticta lichens to monitor the environmental health of Hawaiian ecosystems.

Range-Wide Population Structure of 3 Deepwater Eteline Snappers Across the Indo-Pacific Basin

Deep-sea habitats may drive unique dispersal and demographic patterns for fishes, but population genetic analyses to address these questions have rarely been conducted for fishes in these environments. This study investigates the population structure of 3 tropical deepwater snappers of the genus Etelis that reside at 100–400 m depth, with broad and overlapping distributions in the Indo-Pacific. Previous studies showed little population structure within the Hawaiian Archipelago for 2 of these species: Etelis coruscans and E. carbunculus. Here we extend sampling to the entire geographic range of each species to resolve the population genetic architecture for these 2 species, as well as a recently exposed cryptic species (Etelis sp.). One goal was to determine whether deepwater snappers are more dispersive than shallow-water fishes. A second goal was to determine whether submesophotic fishes have older, more stable populations than shallow reef denizens that are subject to glacial sea-level fluctuations. Both goals are pertinent to the management of these valuable food fishes. A total of 1153 specimens of E. coruscans from 15 geographic regions were analyzed, along with 1064 specimens of E. carbunculus from 11 regions, and 590 specimens of E. sp. from 16 regions. The first 2 species were analyzed with mtDNA and 9–11 microsatellite loci, while E. sp. was analyzed with mtDNA only. Etelis coruscans had a non-significant microsatellite global FST, but significant global mtDNA Ф ST = 0.010 (P = 0.0007), with the isolation of Seychelles in the western Indian Ocean, and intermittent signals of isolation for the Hawaiian Archipelago. Etelis carbunculus had a non-significant microsatellite global FST, and significant global mtDNA Ф ST = 0.021 (P = 0.0001), with low but significant levels of isolation for Hawaiʻi, and divergence between Tonga and Fiji. Etelis sp. had mtDNA Ф ST = 0.018 (P = 0.0005), with a strong pattern of isolation for both Seychelles and Tonga. Overall, we observed low population structure, shallow mtDNA coalescence (similar to near-shore species), and isolation at the fringes of the Indo-Pacific basin in Hawaiʻi and the western Indian Ocean. While most shallow-water species have population structure on the scale of biogeographic provinces, deepwater snapper populations are structured on the wider scale of ocean basins, more similar to pelagic fishes than to shallow-water species. This population structure indicates the capacity for widespread dispersal throughout the Indo-Pacific region.

A new distributional record of the black coral Antipathes cf. griggi in Mactan Island, Philippines

The black coral Antipathes cf. griggi was reported for the first time outside the Hawaiian Archipelago. This short report provides details and short description of the newly recorded species in Mactan Island, Philippines.
