Aiteng
Scientific classification
Domain:	Eukaryota
Kingdom:	Animalia
Phylum:	Mollusca
Class:	Gastropoda
Family:	Aitengidae Swennen & Buatip, 2009^[1]
Genus:	Aiteng Swennen & Buatip, 2009^[1]

Aiteng is a genus comprising three species of sea slug, A. ater and A. mysticus being found in intertidal zones while A. marefugitus is fully terrestrial.^[1]^[2]^[3] Aiteng is the only genus in the family Aitengidae. The generic name Aiteng is derived from the name of a black puppet Ai Theng, which is one of the shadow play (Nang yai) puppets in southern Thailand.^[1]

Taxonomy

Swennen & Buatip (2009)^[1] tentatively classified Aitengidae within the Sacoglossa,^[1] but they noted that some characteristics of the nervous system are similar to those of the Cephalaspidea and Acochlidioidea (mentioned as Acochlidea).^[1]

Aitengidae clusters within the Hedylopsacea as sister group to Pseudunelidae and Acochlidiidae or basal within Hedylopsacea.^[4] Philippe Bouchet (2010)^[5] classified Aitengidae within the superfamily Hedylopsoidea.^[5]

Species

Species in the genus Aiteng include:

Aiteng ater Swennen & Buatip, 2009^[1]
Aiteng mysticus Neusser, Fukuda, Jörger, Kano & Schrödl, 2011^[2]^[6] – This species was found in Hisamatsu, Miyako Island, Okinawa, Japan.^[4] Morphologically it clearly belongs to the Aitengidae, but shows differences to Aiteng ater at genus or species level.^[4] Its affinity to Aiteng ater is confirmed by comparison of the mitochondrial 16S rRNA sequences.^[4]
Aiteng marefugitus Kano, Neusser, Fukumori, Jörger & Schrödl, 2015 - species of sea slug that, remarkably, became terrestrial during the Cenozoic.^[3]

Distribution

The distribution of Aiteng ater includes Thailand.^[1] The distribution of Aiteng mysticus includes Japan.^[4] The distribution of Aiteng marefugitus includes Palau.

Ecology

Aiteng ater lives "amphibiously" in mangrove forests in the intertidal zone, on the mud.^[1]
