Hoploclonia abercrombiei is aspecies of ghost horror knownfrom the northwest of the island of Borneo , more precisely from only one site in the Malay state of Sarawak .
features
In this species, the males are 35 to 40 millimeters and the females 45 to 55 millimeters long. The head, thorax and the second and third segments of the abdomen are covered with paired thorns. In adult males, the thorny areas and especially the thorns themselves are dark brown and therefore usually a little lighter than the rest of the body, which is black-brown in color. At the edges of the tergites of the meso- and metathorax there are two beige to orange-yellow, species-typical marginal ridges. When viewed from above, they appear as two curved lines that converge closer to the rear. The base of the rails is also noticeably yellowish. The females, which are also very dark in color, have shorter thorns, but these are arranged in the same way as those of the males. The end of the abdomen forms a short laying spine for laying the eggs in the ground.
Way of life and reproduction
During the day the animals hide in the leaves or vegetation near the ground. At night they climb up the food plants, and they also never climb areas that are far from the ground. The eggs, which are 3.3 to 3.9 millimeters long and 2.5 to 3.0 millimeters wide, are laid in the ground by the females with the laying stinger. They have a bulging, protruding dorsal area and, as a result, a cover that slopes down towards the ventral side (see also the structure of the phasmid egg ). The nymphs need an average of six months to hatch, but depending on the climate it can be three to eight months. Again, it takes at least six months until the imaginal moult.
Dissemination, Discovery and Systematics
The first male of this species was discovered in 1992 by Philip Bragg in the Niah National Park in Sarawak near the Great Cave of Niah . However, Bragg initially thought it was a male of Hoploclonia cuspidata , from which it differed mainly in the missing pair of spines on the fourth abdominal segment and the slightly different coloration. After a closer examination, he and Ian Abercrombie decided to look again in 1994 at the same site, where three more males and three females were found, two of them copulating . In the following year Bragg described the species and dedicated the species name to Ian Abercrombie. A female is deposited as a holotype in the Natural History Museum in London .
Terrariums
The breeding lines found in the terrariums of lovers go back to the animals found by Bragg and Abercrombie in 1994. Abercrombie successfully bred a pair of these animals. Only small terrariums are needed to keep them. It is important to have permanently high humidity and a layer of substrate at least three centimeters high on the terrarium floor that is suitable for laying eggs. With the leaves of blackberries , strawberries , hazel , oak or rhododendrons , the animals are easy to feed.
For Hoploclonia abercrombiei , the Phasmid Study Group assigned PSG number 165.
