Holotype. Most certainly a juvenile or pre-adult.Considering the general morphology and, in particular the size and structure of the pectines teeth, the specimen is most certainly a female. The specimen is trapped in a very clear block of pale-yellow amber which measures 19x18x 3 mm. The specimen is represented by an exuvia which was totally twisted and dislocated inside the resin; some inclusions and bubbles prevent a 100% observation of all characters. Insects, Coleoptera and Hymenoptera (wasp) are also present.

Diagnosis. – General morphology globally similar to that of other species of fossil and extant chaerilids. The juvenile or pre-adult exuvia has a total length of 14.78 mm. General coloration yellow to reddish-yellow with a few zones slightly darker. Carapace very weakly narrowed toward the anterior edge; anterior margin with a weak concavity; almost acarinate and weakly granulated; furrows shallow. Metasomal carinae weak; only dorsal are better marked; no spinoid granules present on any carinae. Telson incomplete but with a possible pear-like shape. Chela slender and long; dentate margins of fixed and movable fingers with 9 - 10 rows of granules. Pectinal tooth count 9 - 9 in female. Genital operculum not well observable, possibly composed of two sub-oval plates. Trichobothriotaxy of type B, possibly orthobothriotaxic.

Type locality and horizon. – Myanmar ( Burma), Kachin; precise locality unknown; Lower Cretaceous .
