Hermatobates palmyra Polhemus & Polhemus

Palmyra Coral Treader (Hermatobates palmyra)

The Palmyra Coral Treader was described in 2012, it appears to live in the waters around the Line Islands, Kiribati.

The species can also be found around the Mariana Islands. [1]

~~~

The coral treaders inhabit the surface of the ocean, where they search for insects that were blown onto the sea etc.. They are thus actually marine species that are not covered by my blog, however, being insects they may not be thought of as usual marine animals; thus I will mention these creatures in my blog as well.

Metrarga elinguis Ashlock

Mute Seed Bug (Metrarga elinguis)

The genus Metrarga currently consists of only five species, all of which are endemic to the Hawaiian archipelago.

~~~

This species was described in the year 1966.

The males are about 0,6 to 0,7 cm long, the females are slightly larger.

The Mute Seed Bug occurs exclusively on the island of Hawai’i, where it can be found on ‘ie’ie (Freycinetia arborea Gaudich.) and probably also on other native Hawaiian plant species.

Iolania koolauensis Giffard

Koolau Iolania Planthopper (Iolania koolauensis)

The Koolau Iolania Planthopper lives on the island of O’ahu, where it can be found in the northern Ko’olau Mountains at an elevation of 600 to 830 m. The habits of this species are nearly unknown.

The male reaches a length of 0,5 to 0,6 cm, the female is up to 0,7 cm long.

The genus Iolania is endemic to the main islands of the Hawaiian chain, and contains six (currently known) species.

Dryadomorpha lais (Eyles & Linnavuori)

Rarotongan Dryad Leafhopper (Dryadomorpha lais)

The Rarotongan Dryad Leafhopper, originally described as a distinct species, is now often regarded as being identical with the Metrosideros Dryad Leafhopper (Dryadomorpha metrosideri (Osborn)).

I personally, however, doubt that these two species are identical.

Nesolyncides io Fennah

Io Delphacid (Nesolyncides io)

This species, the only one in its genus, was described in the year 1958 on the basis of material, which was collected in 1934 by the entomologist Elwood C. Zimmerman on the island of Mangareva.

The Io Delphacid is very probably one of the few, at least historically known, endemic species of the island, however, whether the species is still extant is not known to me. [1]

Coleotichus adamsoni Van Duzee

Adamson’s Shield Bug (Coleotichus adamsoni)

Adamson’s Shield Bug is about 1,5 cm long, and was described in the year 1932 on the basis of several specimens that have been collected on some islands in the Marquesan archipelago.

The species, however, is also occurring on the Society Islands, at least on the islands of Mo’orea and Tahiti.

One of the known food plants of this species is the native tiatia (Dodonaea viscosa Jacq.). [1]

Leialoha cajeta Fennah

Hivaoa Leialoha Planthopper (Leialoha cajeta)

This species was described in the year 1958.

The Hivaoa Leialoha Planthopper lives on the island of Hiva Oa, where it occurs on the Mt. Temetiu at an elevation of about 1120 to 1280 m.

The species is macropterous and volant, the males are up to 0,3 cm, the females up to 0,4 cm long, the species is obviously not specialized to a particular host plant species, as it can be found on a wide variety of native plant species, including Alstonia costata (G. Forst.) R. Br., Cheirodendron bastardianum (Decne.) Frodin, Cyrtandra spp., Metrosideros collina (J. R. Forst. & G. Forst.) A. Gray, Myrsine spp., Reynoldsia marchionensis F. Br., and Weinmannia spp..

~~~

Up to now, only this single species of this genus has been described from the Marquesas, but there is at least one additional, yet undescribed species on the island of Nuku Hiva. [1]

Nesosydne raillardiicola (Muir)

Raillardia Delphacid (Nesosydne raillardiicola)

This species feeds on at least two of the endemic Dubautia species, Dubautia ciliolata (DC.) Keck and Dubautia scabra (DC.) Keck..

~~~

The photo probably shows this species.

Samoafulvius antennatus Gorczyca

Antenna Capsid Bug (Samoafulvius antennatus)

This bug species (and monotypic genus) was described in the year 2004.

It is an only 0,38 to 0,42 cm long animal, whose light brown colored body is covered with small, scale-like silvery bristles. The sexes appear to be mostly identical. [1]

Nesophrosyne aakokohaikea Bennett

Pale-veined Kanawao Leafhopper (Nesophrosyne aakokohaikea)

The Pale-veined Kanawao Leafhopper is a dark colored species with some pale yellow spots and lines on the wings that form a somewhat face-like pattern when the wings are closed.

The males reach a size of about 0,4 cm, the females are about 0,55 cm large.

This species was described in the year 2011.

It is restricted to the south eastern slope of Mauna Loa on the island of Hawai’i, where it can be found on the leaves of its sole host plant, the kanawao (Broussaisia arguta Gaudich.).

Catacanthus taiti Distant

Henderson Island Stink Bug (Catacanthus taiti)

The Henderson Island Stink Bug occurs exclusively on Henderson Island in the Pitcairn archipelago.

The species was described in the year 1913.

It is quite similar to the more widely distributed Vivid Green Stink Bug (Catacanthus viridicatus Distant), but is more bronzy green colored. [1]

Nesophrosyne broussaisiai Bennett

Maui Kanawao Leafhopper (Nesophrosyne broussaisiai)

This new species, that was described in the year 2011, is restricted to the island of Maui, where the animals can be found on the leaves of the kanawao (Broussaisia arguta Gaudich.).

The Maui Kanawao Leafhopper can be assigned to a species group (kanawao species group), that is so far known only from the islands of Hawai’i and Maui, and that currently contains five species, which resemble each other in appearance, and which are adapted to kanawao as their only host plant.

The males are about 0,42 cm long, while the females are slightly larger.

Kamehameha lunalilo Kirklady

Lunalilo’s Capsid Bug (Kamehameha lunalilo)

The genus Kamehameha (currently) contains three species, of which two are each restricted to a single island (Kaua’i, Nihoa).

Lunalilo’s Capsid Bug, however, occurs obviously on all of the Hawaiian main islands, where it can be found among epiphytic mosses and fern, that cover the branches of the rainforest trees.

It is probably a predacious species.

Atylana rarotongae Eyles & Linnavuori

Rarotonga Plant Hopper (Atylana rarotongae)

This species, described in the year 1974, is endemic to Rarotonga, the largest of the Cook Islands.

It is a small, brownish coloured, chubby creature, about 0,5 cm long, its forewings are translucent and show two darker brown, curved bands, which, however, can sometimes be absent.

~~~

There are perhaps additional species on the other islands of the Cook Archipelago still awaiting their discovery.
