Spinodares jenningsi

The females reach 42.5 to 46 millimetres (1.67 to 1.81 in) in length. The body and legs are colored medium to dark brown. Lighter shades of brown are mainly found in raised areas of the body. In the Pelagus River specimens, an orange-brown line is described running along the 8.5 millimetres (0.33 in) long meso-, the metanotum, the median segment, which together are about 6.5 millimetres (0.26 in) long, and the anterior half of the abdomen. This line was not observed in the females from Mulu. The body is almost parallel-sided, narrowing slightly only in the posterior half of the abdomen. A central ridge (carina) runs across the mesotum, metanotum and abdomen. Near it, the otherwise wrinkled and warty upper surface of the body is relatively smooth. The underside of the body is slightly bumpy in places. On the almost square, 3.5 millimetres (0.14 in) long head are large anterior occipital. The 17.5 millimetres (0.69 in) long antennae consist of 25 segments. The mesonotum is three times longer than the pronotum and almost rectangular. A rising area at the front edge leads to two extremely large spines at the front. They point forward and their tips are almost level with the concave anterior edge of the pronotum. There are two supraoxal spines on the mesopleura, one small, mediolateral, and one very large above. There are two tubercles at its base. …

Spinodares jenningsi is documented from several localities scattered across Borneo. For example, females were found in a logging camp on the Pelagus River and near the Batang Baleh River. Both rivers flow into the Rajang River and are located in the central part of the Malaysian state of Sarawak. Further females have been found in Mulu in northern Sarawak. A male was collected at Bukit Raya at an altitude of about 1,400 metres (4,600 ft) in the Schwaner mountain range in the north of the Indonesian province Central Kalimantan.
