The genus Tisamenus native to the Philippines combines small to medium-sized species of stick insects.
They created an identification key for the Philippine species and divided them into four subgroups according to morphological aspects.
[5] In 2004 the two genera were separated again and the Filipino species were transferred back to the genus Tisamenus.
The short side of this isosceles triangle runs parallel to the leading margin of the mesonotum.
Spines are often found on the lateral margins of the thorax, in pairs on the pronotum, and in the middle of the meso- and metanotum.
As is typical for the representatives of the Obriminae, they have a secondary ovipositor at the end of the abdomen for laying the eggs in the ground, which is rather short in Tisamenus females.
[10][11] Many of the breeding stocks found in the terrariums of enthusiasts initially came into circulation under different names.
The first animals of the genus to be bred in Europe were collected in 2009 by Joachim Bresseel and Thierry Heitzmann in the province of Quezon on the island of Luzon.
[12][13] At the end of November 2008, Heitzmann collected a female in the Quezon National Park, from which another breeding stock can be traced back.
Bressell, Bollens and Mark Bushell also found other animals on Luzon in the province Aurora near the city of San Luis in Cunayan.
Although these have more or more pronounced spines, particularly along the middle of the body, they are also classified as the very variable Tisamenus lachesis.
The resulting breeding strain was long referred to as Tisamenus deplanatus 'Pocdol' and was given the PSG number 399 by the Phasmid Study Group.
[7][11][12][13] At the beginning of June 2014, Albert Kang brought animals from the island of Sibuyan that were initially named and distributed as Tisamenus sp.
Another breeding stock goes back to two very differently colored females that Heitzmann and Kang collected on November 5, 2014 in a protected area near the Callao Cave in the province of Cagayan.
A sexual breeding stock was established from the eggs laid by these females, which was initially distributed as Tisamenus sp.
The adult females are characterized by a longitudinal orange stripe and the males have an almost orange-red body coloration.
Heitzmann found specimens on July 22nd at Mount Bagacay and on August 4th, 2015 at Mananap Waterfall in the province of Camarines Norte that were initially bred as Tisamenus cf.
'Ifugao', which was collected in October 2013 by Heitzmann and Kang, and Tisamenus hebardi, which was collected in April 2014 by Heitzmann, Bresseel and Jérôme Constant in the cloud forest on Mount Polis and was initially called Ilocano hebardi 'Sagada'.
They willingly feed on various forage plants such as bramble, hazel, firethorn, ivy and Hypericum.
