Dares philippinensis is a member of thegenus Dares, which belongs to the ghosts . This species is notnativeto Borneo ,like most of the other members of the genus, but to the Philippine island of Palawan .
features
The wingless animals in both sexes show the habitus typical of the genus . The sensors consist of 24 segments. Your basal phalanx (scapus) is flat and has a tooth on the outside. The 4.3 to 4.5 cm long females have a body surface covered by tubercles . While most of the other females of the genus have no spines, the females of Dares philippinensis can often have relatively clear spines at the widest point of the meso- and metanotum on the lateral edge, with one short sting per segment and side. In this way, four spines can be seen in the top view. The coloration of the females is more contrasting than that of the males. Usually a lighter brown dominates, which often deviates into a reddish shade. There are also darker animals and those with dark brown patterns. The pair of white spots at the base of the abdomen, which is typical for many older nymphs of the genus, is often still to be found as a light area in the adult females of this species. Overall, the females resemble those of Dares verrucosus . This also applies to the 3.4 to 3.5 cm long males. Their basic color is usually a light brown. Black spots or dots can be found especially on the back of the meso- and metanotum and can merge to form lines. In addition, there is usually a black-brown continuous line along the pleura of the meso- and metathorax . There are no distinct spines on the top of the meso- and metanotum. Only on the side are four spines in the same places, where they can also occur in the females. The males also have four distinct spines on their heads. The rails of her legs are colored black. On the upper side of the abdomen there are small processes on the segments that grow larger towards the end of the abdomen.
Occurrence and way of life
So far, Dares philippinensis has only been found on the Philippine island of Palawan .
In their nocturnal way of life and defensive behavior, it is similar to the other Dares species. In Dares philippinensis , too , the defense strategy consists of phytomimetry . This is achieved through color and body shape, but also through behavior in the event of disturbance (dropping and paralysis ). The eggs are almost spherical and dark brown in color with light brown spots and a few thick bristles. One of the three arms of the micropylar plate reaches the edge of the lid, the other two run circularly around the egg.
Discovery, Taxonomy and Systematics
The first specimen of the species, a female nymph, was found by R. Rodriguez in 1974 on Palawan. C. L. Chan found other animals, both adults and nymphs, also on Palawan at Brooke's Point in 1983 . In 1994 he left this to Philip E. Bragg , who recognized it as a representative of a new species and described it in 1998. The specific epithet chosen by him philippinensis indicates the special position of the species in the genus, which is currently the only Filipino Dares species. It also leaves open whether the species, which has so far only been found in Palawan, also occurs on other islands in the Philippines. An adult female has been deposited as a holotype at the Natural History Museum in London . This is one of the animals that Chan collected. Further copies of this collection are also deposited as paratypes at the Natural History Museum. The same applies to the nymph that Rodriguez collected.
Terrariums
Dares philippinensis entered European terraristics as the fifth species of the genus . The first animals were born around 2010/2011 by the Dutch - Belgian Phasma under the name Dares sp. "Philippines" distributed. The species is easy to keep and breed if a higher humidity is maintained and a slightly moist substrate is offered on the ground. The leaves of blackberries and many other rose plants are eaten .
The Phasmid Study Group has listed Dares philippinensis under PSG number 331 since mid-2013.
