Worker. Length 3.5mm The head is longer than wide, very convex posteriorly, weakily narrowing, with sides slightly convex. Eyes very large situated behind the posterior 1/3 of the head. The frontal carinae are very distinct,the distance between them is greater than the distant from the edge of the head. No frontal groove, it is replaced at the front by a weak line or carina. Frontal area and clypeus very poorly margined. Clypeus carined. Antennae are articulated well behind the posterior angles of the clypeus (as in the genus Camponotus) to the side of the middle of the frontal carinae. Clypeal pits are small, a long way from the antennal pits. Pronotum and mesonotum form together a strong almost hemispherical vault. The suture between mesonotum and metanotum is very deep, much deeper than in all other species and at the same time as wide at the bottom as the distance between the two stigmata which it encloses. The metanotum (= propodeum) is very elevated and cut vertically in front and behind. The basal face is very convex and a little longer than wide. The declivity is vertical even slightly concave, forming an angle a little more than 90o (although rounded in transition) to the basal face. The node is high, thick, vertical, flat behind, strongly convex at the front, entire or slightly indented at the summit. Abdomen strongly convex above as in the case of the other species. Limbs and antennae of moderate size (about like P obscura); length of scape about 1mm. Shining, weakly wrinkled or reticulate wrinkled. On the metanotum (= propodeum) the wrinkles or reticulation are a little stronger , concentric and a microscopic sculpture appears to exist at intervals that diminishes the luster. The whole body including the limbs and antennae quite particularly the scapes and tibias are provided with a very abundant fine pilosity rather long and pointed which is entirely different from the rigid and obtuse setae of most of Prenolopsis. Flat-lying pubescence is almost lacking. Black to dark brown. Mandibles clypeus, extremities of the antennae and of the tarsi also some articulations and sutures of a more or less light brown.

This curious species is so aberrant one would be tempted to make it a different genus. However its general appearance,its abdomen even its antennae a long way from the clypeus make it a Prenelopsis It appears ,because of its pilosity to be close to Prenolopsis sumatrensis Mayr of which only the male and female are known from which she differs considerably.
