Agosti, Moog & Maschwitz, 1999
This species has been collected from Drypetes longifolia and Ryparosa fasciculata. Cladomyrma nudidorsalis seems to be much less common than the syntopic Cladomyrma petalae, but this is based on the eclectic set of field collections and existing specimen records gathered for this study. (Agosti et al. 1999)
Agosti et al. (1999) placed Cladomyrma species into two groups based on the shape of the queen's petiole, raised (an erect node or scale) or depressed (dorsally truncate and low). Cladomyrma nudidorsalis belongs to the depressed petiole group.
This species is easily recognized in the queen by the lack of erect hairs on the dorsum of the alitrunk and the very short hairs on the gastral tergites, unique characters within the genus. However, other queen characters are very similar to those of Cladomyrma petalae (e.g., size, body color, petiole, pubescence), and the distinction from C. petalae is mainly based on the difference of the distribution of setae, a rather variable character in C. petalae. Another trait may prove to be of importance: the workers of C. nudidorsalis tend to be of a lighter body color than C. petalae, but a larger sample size is needed to assess possible variation.
