They point forward and their tips are almost level with the concave anterior edge of the pronotum.

Two pairs of large tubercles are on the posterior edge of the mesonotum, surrounded laterally by three to four smaller ones.

At the posterior edge of the eighth segment, the longitudinal crest forms a small triangular pyramid.

Two large triangular spines are present on the mesonotum in front, the tips of which are connected by a concave bulge.

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.

[4] 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.

The holotype of Spinodares jenningsi is a female found in a logging camp on the River Pelagus and deposited at the Natural History Museum in London.

One female survived at Paul Jennings for about one year and laid eggs during this time, from which nymphs hatched, which were fed with bramble leaves.

The originally collected specimens, as well as eight nymphs from Jennings offspring and some eggs laid by the holotype are deposited as paratypes in the Natural History Museum, the Oxford University Museum of Natural History, the Naturalis Biodiversity Center in Leiden and in Jennings' private collection.

[2][3] In 2004, Oliver Zompro described the previously unknown male based on a specimen from the Zoological Museum in Hamburg that had originally been stored in alcohol.
