Brasidas foveolatus is a species of stick insects from the family Heteropterygidae. Next to Brasidas samarensis it is one of the most famous representatives of the genus Brasidas .
Josef Redtenbacher described this species as Obrimus foveolatus in 1906 based on a male originally deposited in the Muséum national d'histoire naturelle. James Abram Garfield Rehn and his son John William Holman Rehn transferred the species in 1938/39 along with another species to the newly established genus Brasidas. In this they not only described four more new species, but with Brasidas foveolatus asper also a new subspecies of Brasidas foveolatus based on a single male. This male has been deposited as holotype in the National Museum of Natural History. It differs from the type specimen of the nominate subspecies, which has meanwhile been regarded as missing, in particular by the structuring on pro- and mesonotum, e.g. in the expression of spines and tubercles. [1] [2]
In habitus the species corresponds to typical representatives of the Obrimini e.g. Trachyaretaon or Obrimus species. As with all Brasidas species, Brasidas foveolatus also has a pair of characteristic holes in the metasternum. At around 80 to 95 millimetres (3.1 to 3.7 in) in length, the females are significantly larger and plump than the approx. 55 to 65 millimetres (2.2 to 2.6 in) long males. In both sexes, brown, more rarely olive-brown colors dominate. The more vividly drawn and more variable females can show light, mostly greenish areas, especially on the lateral and rear edge of the metanotum. Furthermore, numerous black tubercles on the head and the thorax are clearly differentiated from the brown base color. Often there is also an almost white area that extends from the middle of the sixth to almost the entire width of the seventh abdominal segment. There is almost always a pair of black spots on the eighth segment. With this combination of colors, the end of the abdomen, together with the ovipositor, is reminiscent of a head, more precisely a bird's head. Occasionally there are also females who wear a wide, white longitudinal band over the entire body on a brown background, which is then also supplemented by the black spots on the eighth segment of the abdomen. Adult males are mostly monochrome brown and like the females only slightly prickly. [3]
Brasidas foveolatus is native to the Philippine archipelago Mindanao. [1]
The 4 to 5 millimetres (0.16 to 0.20 in) long and 2 to 3 millimetres (0.079 to 0.118 in) wide eggs are laid in the ground as with all Obrimini by means of the ovipositor at the end of the abdomen. Their eggshell (exochorion) is gray and becomes darker when the humidity is higher and lighter again when it is dry. The dorsal area is bulging and the lid (operculum), which is always dark gray sits on the egg, sloping towards the ventral side, so that an opercular angle of about 10 degrees is created. The nymphs hatch from the eggs after about four months and then need another four months to grow. [4]
The first representatives of this species found their way into the terrariums of enthusiasts in 2008. They came from Mindanao and were collected there in Nabunturan and at Lake Agko near Mount Apo. The species is listed under PSG number 301 by the Phasmid Study Group.
Brasidas foveolatus can easily be fed with leaves of bramble and other Rosaceae, as well as oak, ivy or Hypericum . Occasionally the forage plants should be sprayed with water. In order to enable eggs to be laid, the floor of the terrarium should be covered a few centimeters high with a slightly moist soil substrate. [3] [5]

The Obriminae are the most species-rich subfamily of the Phasmatodea family Heteropterygidae native to Southeast Asia. It is divided into two tribe.
Hoploclonia is the only genus of the tribe Hoplocloniini and brings together relatively small and darkly coloured Phasmatodea species.
Mearnsiana is a monotypic genus of stick insects, containing Mearnsiana bullosa as the so far only described representative.
Aretaon is a genus of stick insects native to Borneo and the Philippine island Palawan.
Trachyaretaon is a genus of stick insects native to the Philippines.
Brasidas is a genus that is native to the Philippines and is named after the Spartan general Brasidas
Obrimus is a stick insect genus native to the Philippines. It is type genus for the tribe and the subfamily in which it is listed.
Aretaon asperrimus is a species of insect in the Aretaon genus of the Phasmatodea order. The sometimes used common name thorny stick insect is a bit misleading, since the species does not correspond to the typical stick-like habitus and many other species are thorny as well.
Dares murudensis is a relatively small species of stick insect. Like most other members of the genus Dares, the species is native to Borneo.
Dares verrucosus is a species of stick insects. Like most other members of the genus Dares, the species is native to Borneo, more precisely in the north of the island.
Trachyaretaon carmelae is a species of stick insects. Even if there was no formal synonymisation, Trachyaretaon brueckneri is generally used as its synonym.
Tisamenus deplanatus is a stick insect species native to the Philippine islands Luzon and Mindanao occurs.
Brasidas samarensis is stick insect species from the family Heteropterygidae. Occasionally it is named Samar stick insect according to their origin. In addition is the type species of the genus Brasidas, which was named after the Spartan officer Brasidas.
Hoploclonia cuspidata is a stick insect species native to the north of Borneo and is also called Brunei Hoploclonia stick insect.
Hoploclonia abercrombiei is a stick insect species known from the northwest of Borneo, more precisely from only one place in the Malay state Sarawak.
Trachyaretaon echinatus is a species of the order of the stick insects native to various Philippine islands.
Haaniella scabra is a species of stick insect native to Borneo and a typical representative of the subfamily Heteropteryginae. The occasionally used common name Small Haaniella refers to the size of this.
The genus Euobrimus is a Philippines-native stick insect genus that is very similar or synonymous with the genus Brasidas.
Euobrimus cavernosus is a representative of the stick insects native to the Philippines. It is considered one of the largest species in the subfamily Obriminae.
