Asteliaphasma distribution

Asteliaphasma is a genus of stick insects (order Phasmatodea) belonging to the family Phasmatidae. [1] The genus is endemic to New Zealand and the species were first described by Salmon in 1991 [2] and later moved to the genus Asteliaphasma. [3] [4] Members of this genus are found in the forests of the North Island, where they have been collected at elevations up to 900 meters above sea level. [5] [6] Asteliaphasma are nocturnal, apterous (wingless), arboreal stick insects that feeds on Astelia and rātā species. [7] [6] [8]

Species: [9]

As of 2014, both species are considered not threatened by the New Zealand Department of Conservation (DOC). [4]

Taxonomy and phylogeny

The genus is named from the plant genus Astelia (family Liliaceae), combined with the suffix "phasma" meaning "phantom" or "insect" (reference to stick insects). [6] The species is so far only known from Astelia species and the Astelia-like Freycinetia banksii (Pandanaceae) and climbing rātā. [6] [8]

One species, Asteliaphasma naomi, for a long time was known from a single specimen, but has now been collected a number of times. [10] [11]

Early classifications suggested that Asteliaphasma was a sister group to Spinotectarchus ; however, recent molecular data indicate that they are not sister taxa. [10] [6] Instead, phylogenetic analysis indicates that A. jucundus is more closely related to Niveaphasma and Micrarchus species. [10] [7] [12]

Morphology

Asteliaphasma are small, slender and completely wingless stick insects. [6] Until 2005 only female A. jocunda had been recorded [8] so reproduction of some populations might be parthenogenetic, a pattern consistent with that observed in other New Zealand stick insects. [6] [7] Adult female A. jucundus range from 64 to 88 mm in body length and males are thiner and shorter (5mm). [6] [8]

The following key features are used to identify this genus: [6]

Asteliaphasma eggs are elongated, cylindrical, finely pitted and lightly rugose with minute spine-like setae restricted to the anterior and dorsal regions. [6]
