Obrimus (phasmid)
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. Characteristics. The species of this genus correspond in the habitus to the other representatives of the Obrimini, appear somewhat longer-legged compared to these and also have longer antennae than these. Like almost all other Obrimini, they are wingless in either sex. They are similar in size and appearance to the species of the genera "Brasidas". As with these, the females have a relatively long and straight ovipositor that surrounds the actual ovipositor . Most Obrimus species have more and more pointed spines, which, however, are often thinner than those of most other Obrimini species. Compared to the representatives of "Brasidas" and "Euobrimus" there are only poorly or partially barely recognizable, flat slits or pits and none holes at the outer edge of the metasternum. The shape of the eggs also differs significantly from that of other genera. The eggs are long and wide. The micropylar plate has three arms and is located on the dorsal area, which is bulging. The egg shape is reminiscent of that of "Sungaya" eggs. However, behind the tip  at the lower pole there is another blunt pole, so that the eggs below, more or less clearly recognizable, have two blunt ends. The lid (operculum) sits diagonally on the egg and falls off sharply to the ventral side. Taxonomy. The genus "Obrimus" was established in 1875 by Carl Stål. The generic name is borrowed from Greek mythology. As the only species, and thus type species, Stål named "Obrimus bufo", which until then was listed in the genus "Acanthoderus". Other species were later transferred to the genus or described in it. In the meantime most of them have been transferred  to the younger genera "Aretaon", "Trachyaretaon", "Brasidas" and "Euobrimus". Remaining in the genus are: Distribution. Of the representatives known so far, only the occurrence of the two species described by Rehn and Rehn is known in more detail. Both appear on Luzon. While "Obrimus bicolanus" comes from the southeast of the island, more precisely from the Bicol region, "Obrimus uichancoi" was collected in the north in the province Apayao. Only the Philippines are given as location of the two other species. Terraristic. A single representative of the genus is currently in the terrariums of lovers. The stock goes back to  specimens that Thierry Heitzmann collected in 2010 on Luzon and bred for the first time. The species was brought to Europe in 2011 by Bruno Kneubühler, also distributed as "Obrimus" sp. 'Pulog'. The Phasmid Study Group lists the species under the name "Obrimus bicolanus" (?) and PSG number 324.
