Taxonomy

G. algarum shares several characteristics with both G. fucorum and G. gracilis, leading some to believe that the three are a single polytypic species consisting of highly individual subspecies. G. algarum is differentiated from the other two centipedes by having two labral teeth, a clear clypeal area, 8–12 prehensorial teeth, three ventral (posterior) and one dorsal coxal pore, and a well-developed claw of the anal leg.^[3]
