Dares murudensis is a relatively small species of stick insect. Like most other members of the genus Dares, the species is native to Borneo.

Characteristics

The species is the smallest of the genus Dares. The females are only 26 to 35 millimetres (1.0 to 1.4 in) long. The males remain even smaller with about 25 to 30 millimetres (0.98 to 1.18 in) length.

habitus
.

The females have a raised, square area on the head on which there are differently pronounced front, central and rear occipital

abdomen there is a longitudinal ridge (carina) that is indistinct in the first two segments and more distinct in segments three to six. The lateral edges of segments four and five are enlarged by indistinct tubercles. There are no tubercles on the edges of the second and third segments. The posterior tubercles of segments three to six are very small and paired. The middle longitudinal ridge is forked at the rear on the eighth segment. Likewise on the ninth segment, where it is tall and narrow. Segment ten contains a pair of tubercles near the anterior margin and short lateral ridges near the posterior margin. Its tip is straight and has no indentations. The femura of all legs are covered with tubercles at the edges. The meso- and metafemures have a pair of small spines or pointed tubercles at the tips of the ventral edges. All tibiae
are free of tubercles.

The body surface of the males is dull and colored red to black-brown. Clearly developed spines on the thorax, as they are present in other representatives of the genus, are absent. In the rear area of the upper side of the meso- and metanotum there is only one pair of elevations each, which culminate less in a point than in a larger tubercle. Similar structures are found in the rear area of the metapleura above the rear coxae. In contrast to Dares philippinensis they are missing on the mesopleurs. On the back of the head, the two pairs of the anterior and posterior coronals form a crown of four short spines, similar to those found in other species.[2][3][4][5]

Distribution area

Dares murudensis is known from various localities in northern Borneo. The female on which the first description is based was found on

Crocker Range Mountains, which separate the east from the west coast of Sabah. The species was found there in 2006 near Keningau and later also near Tambunan. Based on the findings so far, there are indications that the animals living in higher altitudes remain smaller than those from lower ones.[3]

Way of life

As food plants are Rosaceae such as (Rubus moluccanus), Myrtaceae such as Eugenia species and Psidium guajava known.[1] In its nocturnal way of life and the phytomimesis used for camouflage during the day, it is similar to the other Dares species. The eggs are about 3.2 millimetres (0.13 in) long, but only a good 2 millimetres (0.079 in) wide and, due to the large lid (operculum), not quite spherical. They are dark brown in color and marked with light brown spots around the few bristles. One of the three arms of the micropylar plate reaches the edge of the lid, the other two run circularly around the egg. The nymphs, which hatch from the eggs after about 4 months, are then about 10 millimetres (0.39 in) long. It takes about 10 to 12 months until they are adult.[5]

Discovery and taxonomy

Philip Edward Bragg described Dares murudensis in 1998 on the basis of an adult female, which Eric Georg Mjöberg was collected at the eponymous Mount Murud. This holotype, from which Bragg was able to remove an egg from the abdomen, is deposited in the Naturalis Biodiversity Center in Leiden. When this female was collected is not known.[2] Bragg himself and Paul Jenning collected live specimens of this species on December 25, 2006, near Keningau in the Crocker Range National Park in Sabah, about 170 kilometers north of Mount Murud. Without realizing that the species had already been described, it was successfully bred as Dares sp. 'Crocker Range'. Their affiliation to Dares murdensis was first recognized by Thies H. Büscher in 2014.[3][6]

Terraristic

Dares murudensis has been the fourth and smallest species of the genus since 2007 in European

bramble and other Rosaceae as well as hazel are eaten. The species has been listed under PSG number 332 by the Phasmid Study Group since 2013.[5][7][8]
