Description
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
The only male documented to date measures 324 millimetres (12.8 in). A lighter line along the middle of the body on an otherwise brown coloration was also described in this male. The head is 3.5 times as long as it is wide. The supratennals are formed as spines. On the back of the head is a crown consisting of three coronal spines on both sides. The anterior coronals are the smallest and point forward, the middle ones are prominent and thick, while the posterior ones are long and pointed. On the pronotum there are short spikes in front behind the anterior edge, more in the middle and a third pair just before the rear edge. Two large triangular spines are present on the mesonotum in front, the tips of which are connected by a concave bulge. The light midline is elevated and extends from the mesonotum through the metanoum to far into the abdomen. On the mesonotum, this divides backwards and is surrounded by a triangular area. On the metanotum it is indistinctly forked backwards. On the second to fourth abdominal segments it is bifurcated forwards and backwards, with the anterior bifurcation becoming increasingly indistinct from segment to segment. The rear furcation is sharply raised on the fifth segment and progressively round rather than triangular on the sixth through ninth.[4][5]
The eggs are dark brown, cuboid and unique among the Datamini due to the three concave dents on both lateral sides. With a height of 2.2 millimetres (0.087 in) and a width of 1.6 millimetres (0.063 in), they are 3.7 millimetres (0.15 in) long and twice as long as they are wide. The surface is covered with numerous hairs, most numerous in the pole and lid area, while very few are found on the lateral surfaces. The lid is oval.[2][3][4]
Distribution area
Spinodares jenningsi is documented from several localities scattered across Borneo. For example, females were found in a logging camp on the Pelagus River
