Cladoxerini ( Syn . : Baculini) is a tribe of rod-shaped ghosts (Phasmatodea) within the family of Phasmatidae .

features

The Cadoxerini show the typical habitus of stick insects . They differ from the other tribes of the Cladomorphinae by the serrated upper edges of the fore legs ( Profemora ) and the relatively short antennae , which have no more than 30 segments (antennas). Overall, the antennae are slightly shorter than the fore legs. Their limbs are somewhat elongated in the males. Females are wingless and have a very elongated, lanceolate, spatula or boat-shaped subgenital plate ( apical sternite ). Males are winged, often only with scale-shaped forewings formed as tegmina and well-developed hind wings (alae), the anal fields of which are transparent. All in all, the species are rather larger, with the females of some representatives including the subgenital plate reaching lengths of up to 24 cm.

distribution

The representatives of the genera Cladoxerus and Wattenwylia are native to the southeast of South America , more precisely in southeast Brazil , Paraguay , Uruguay , Argentina and Bolivia . The only species of the genus Parabactridium was described by Josef Redtenbacher on the basis of females, which are said to come from Madagascar . Their membership of the Cladoxerini has been questioned several times. Since the type material is considered lost, a clarification is currently not possible. Due to some features found in the description, such as a body length of only 9 cm, relatively short legs, a thorn on the head and others, an assignment to the Antongiliinae or the Achriopterini native to Madagascar is discussed.

Systematics

The tribe goes back to the subfamily Cladoxerinae described by Heinrich Hugo Karny in 1923 . While the subfamily was drafted in 1982 by Douglas Keith McEwan Kevan , the tribe first mentioned by Klaus Günther in 1953 with the type genus Cladoxerus is still valid. Since in 2016 by Frank Hennemann et al. Even the last five representatives of the genus Baculum, established by Henri de Saussure in 1861, including the Baculum ramosum listed as a type species , were transferred to the genus Cladoxerus , since then the Baculini tribe has also been considered a synonym for Cladoxerini.

The following species are assigned to the three genera:
