Atyphella is a genus of 'flashing' firefly (family Lampyridae) found in the Australasian region, particularly in the eastern and northern regions of Australia. The genus consists of 23 recognized species,[2] 14 considered to be endemic to Australia.[3]
The larval stage of Atyphella is morphologically similar to the Luciola larval stage, the key difference being that the Atyphella possess a series of flat projections on the sides of the body (known as explanate tergites).[4]
Atyphella antennae are relatively short, shorter than the widest part of the head. This is almost unique among the genera of the subfamily Luciolinae with Bourgeoisia being the only other to feature this.[4]
The adult Atyphella head is concealed under an extended pronotum and recessed into the prothoracic cavity.[5] This effectively eliminates upwards vision when in flight and in a resting state. However, it has been observed that some species can extend the head beyond the pronotum in active searching when on the ground.[4]
Other notable morphological features of the genus Atyphella include a head longer than it is wide and ventrally subcontiguous eyes.
The taxonomic ranking of the Atyphella has been somewhat disputed. It was originally described in 1889 as a separate genus under Lampyridae. This was changed in 1964 when it was grouped under the genus Luciola as a subgenus (along with Pygoluciola).[6] In 2000 it was again distinguished as a separate genus. This is the current accepted taxonomy, sitting as a sister group to Pygoluciola.[3]
