Panesthia lata, the Lord Howe Island wood-feeding cockroach or Lord Howe Island cockroach, is a large, wingless cockroach species endemic to the Lord Howe Island Group in the Tasman Sea. [1] [2]

Contents

Appearance and diet

Panesthia lata is reasonably large, growing between 22–40 millimetres (0.87–1.57 in). [3] [4] [5] It is metallic in colour, with general black to reddish colouration. [3] [4] It can be distinguished from other related species by its shape and the markings on its thorax. [6]

The species feeds on rotting wood and leaf litter, and has micro-organisms in its digestive system to help break down cellulose. [3] [5] It stays in the ground during the day and feeds at night. [5]

Population

While once widespread across the archipelago, it was removed from Lord Howe Island proper by rats introduced in 1918, and none have been found for over 60 years. [1] [3] [4] Today, the only known populations occur on nearby islets, including Blackburn Island, Roach Island and Ball's Pyramid. [1] [5] The species is classified as "Endangered" under the New South Wales Threatened Species Act, and a plan exists to eventually reintroduce a population to Lord Howe Island. [7]

Taxonomy

Panesthia lata was first described in 1868 by Francis Walker in his "Catalogue of the specimens of Blattariæ in the collection of the British Museum". [4] [8] [6] It is in the subfamily Panestheiinae, which is distributed across Southeastern Asia and Oceania.

Rediscovery on Lord Howe island

After not having been observed on Lord Howe Island for over 80 years, a biology student at the University of Sydney rediscovered them on the island in late 2022. [3] [5]

Lord Howe Island is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies 600 km (320 nmi) directly east of mainland Port Macquarie, 780 km (420 nmi) northeast of Sydney, and about 900 km (490 nmi) southwest of Norfolk Island. It is about 10 km (6.2 mi) long and between 0.3 and 2.0 km wide with an area of 14.55 km2, though just 3.98 km2 of that comprise the low-lying developed part of the island.

<span class="mw-page-title-main">White swamphen</span> Extinct species of rail from Lord Howe Island

The white swamphen, also known as the Lord Howe swamphen, Lord Howe gallinule or white gallinule, is an extinct species of rail which lived on Lord Howe Island, east of Australia. It was first encountered when the crews of British ships visited the island between 1788 and 1790, and all contemporary accounts and illustrations were produced during this time. Today, two skins exist: the holotype in the Natural History Museum of Vienna, and another in Liverpool's World Museum. Although historical confusion has existed about the provenance of the specimens and the classification and anatomy of the bird, it is now thought to have been a distinct species endemic to Lord Howe Island and most similar to the Australasian swamphen. Subfossil bones have also been discovered since.

<span class="mw-page-title-main">Lazarus taxon</span> Taxon that disappears from the fossil record, only to reappear later

In paleontology, a Lazarus taxon is a taxon that disappears for one or more periods from the fossil record, only to appear again later. Likewise in conservation biology and ecology, it can refer to species or populations that were thought to be extinct, and are rediscovered. The term Lazarus taxon was coined by Karl W. Flessa and David Jablonski in 1983 and was then expanded by Jablonski in 1986. Paul Wignall and Michael Benton defined Lazarus taxa as, "At times of biotic crisis many taxa go extinct, but others only temporarily disappeared from the fossil record, often for intervals measured in millions of years, before reappearing unchanged". Earlier work also supports the concept though without using the name Lazarus taxon, like work by Christopher R. C. Paul.

The Lord Howe long-eared bat was a vespertilionid bat known only by a single specimen, a skull found on Lord Howe Island in 1972. A mammalian insectivorous species resembling the long-eared Nyctophilus, with an elongated head that is comparatively larger, about which almost nothing is known. The bat may have been casually observed in flight during the twentieth century, but is likely to have become extinct since the island's discovery and occupation. The demise of N. howensis is possibly the result of shipwrecked rats and the owls introduced to control them.

The Lord Howe Island skink is a part of the native Australian reptiles’ classification. The Lord Howe Island Skink is a species of skink in the family Scincidae, located on Australia's Norfolk Island and Lord Howe Island. The Lord Howe Island skink population is uncommon to be found on Lord Howe island, however the majority of their population is located on the Norfolk Island complex.This skink is metallic bronze in colour and has flecks for defining features. It can grow up to 8cm in length, making them medium in size. Its taxonomy is diverse, the skink is a part of the Scincidae family, Oligosoma genus. This skink population is protected and considered vulnerable under the Environment Protection and biodiversity conservation act 1999.

<span class="mw-page-title-main">Lord Howe gerygone</span> Extinct species of bird

The Lord Howe gerygone or Lord Howe gerygone flyeater was a small bird in the family Acanthizidae, brown and greyish in color. Its head was brown apart from a pale grey eye-ring and a grey throat and chin, many parts of the animal varied to the colour of yellow, this being apparent in its bright yellow belly. It made its home in the canopies of the island's forest until the early 20th century. The bird has had a variety of monikers: locally, it was known as the "rain-bird" due to its activity after the rains, or the "pop-goes-the-weasel", due to the similarity of its song to the well-known tune. The bird was endemic to Lord Howe Island in the Tasman Sea. There have been no records of the species since 1928, and it is considered to be extinct. Its extinction is almost certainly due to predation by black rats which were accidentally introduced to the island in 1918 following the shipwreck of the SS Makambo there.

Dryococelus australis, commonly known as the Lord Howe Island stick insect or tree lobster, is a species of stick insect that lives on the Lord Howe Island Group. It is the only member of the monotypic genus Dryococelus. Thought to be extinct by 1920, it was rediscovered in 2001. It is extirpated in its largest former habitat, Lord Howe Island, and has been called "the rarest insect in the world", as the rediscovered population consisted of 24 individuals living on the small islet of Ball's Pyramid.

Spots of various colours occur on its sides. After a dramatic population decline in the late 20th century, the fish was thought to be locally extinct in several areas, but was rediscovered both in South Australia and Victoria in the 21st century.
