I'd like to thank Graham for these nice images of an otherwise obscure taxon seen and recognized by few. Please continue photographing and submitting images.

Diceroprocta biconica
Another image of D. biconica.

Although T. davisi has been recorded in the Florida Keys, I have not personally seen it that far south. Additionally, based on personal communications with others, T. davisi seems rather sparse in its distribution across the southern most parts of the state.

Typically, T. davisi does not have strong pruinose markings on the dorsum of the abdomen, if at all - in fact, none of the many 100's I have seen or collected through the years possess such pruinose markings at all.

In contrast, Diceroprocta biconica is characterized by a broad pruinose band at the anterior of the abdomen (as seen in D. cinctifera) - which the cicada in this pic clearly possesses!

Also note the following in this specimen:
1) Broad pruinose band at the anterior of the abdomen (a strong characteristic of D. biconica!)
2) Locality - Florida Keys, where D. biconica is well recorded and COMMON! (NOTE: There are 2 or more defined Cuban populations/subspecies of D. biconica and they are not identical in appearance to populations occurring in the FL Keys - however, they are very similar!!)
3) It is important to note that in some individuals of Diceroprocta spp. head width can be highly variable in its proportions to the thorax and may exceed those dimensions.
