Brescovit leg. (MCN-21438) . Etymology. The specific name refers to Drogon, one of Daenerys’ three dragons, a fictional creature in R.R. Martin’s book series “A Song of Ice and Fire”. Noun in apposition. Diagnosis. The male of Myrmecotypus drogon spec. nov. resembles those of M. rubrofemoratus and M. formicus comb. nov. by the tibia I ventral spination 3-3 and the presence of a tegular process in the male palp; they differ from those of both species by the curved embolus, longer than the RTP and tegular process (compare Fig. 15D with Fig. 14D, I ).
