Data Mini is the only tribe within the subfamily of Dataminae from the order of Gespenstschrecken (phasmatodea). The representatives of this subfamily are on average not as large as those of the other two subfamilies belonging to the Heteropterygidae family.

features

The Datamini species remain relatively small for ghosts. In females, the body length varies between 2.5 and 5 cm, depending on the species. The males remain somewhat smaller with a body length of less than 2 to 4 cm. All species are wingless in both sexes. The females lack the pointed laying spine at the end of the abdomen, which is typical in the other subfamilies and which surrounds the actual ovipositor . Your abdomen ends bluntly. In adult females, the abdomen is enlarged and significantly increased towards the middle due to egg production. Males have a rounded central abdomen area, which is thinnest here. Pointed spines can be found in many species, especially in the males. Alternatively, the body can be covered with wart-like tubercles. The latter is more common in females. Most of the species are monochrome beige, brown or black-brown colored or patterned in these colors.

Distribution and way of life

Many representatives of the Dataminae are native to Borneo . There are also species on the islands of Sumatra , Java and Palawan . There are also other representatives from Japan , South China , Hong Kong , Vietnam , Laos and Thailand via Sulawesi to New Guinea . The way of life of the nocturnal animals, as well as the defense strategy, is based on mimetics . The animals often move only slowly or not at all when touched for a long time. During the day the ghosts usually hide in the leaves and at the foot of plants. To eat, they often only climb a few centimeters on the food plants. The females usually lay only a few, but relatively large eggs on the ground or in the leaves. It takes between two and six months for them to hatch. The nymphs always grow very slowly. Adults can live between one and five years.

Systematics

The names of the subfamily and tribe go back to the genus Datames established by Carl Stål in 1875 , which he named after the Persian official and general Datames . In 1904, James Abram Garfield Rehn established Datames oileus, which was described by John Obadiah Westwood in 1859 and was the earliest described species as a type species . In 1939, JAG Rehn and John WH Rehn summarized some genera in the Tribus Datamini, which Klaus Günther raised to the rank of subfamily in 1953. It was only in 1998 that it emerged that the type species Datames oileus belongs to the genus Pylaemenes . The genus Datames was synonymous , while the names for the subfamily and the tribe were retained. The species of the subfamily Dataminae, which at the same time all belong to their only tribe Datamini, are divided into the following seven genera:
