Asiodiplatys is a

tegmina and hind wings that folded up into a "wing package" that are like modern earwigs.[3] Like Archidermapteron martynovi, the only clear fossil of the species was found in Russia.[4]

Discovery

Like other extinct species of earwig, little is known about how Asiodiplatys speciousus was discovered due to the ambiguity of the reports about it, and the fact that only one fossil of it was ever found.[3] The reason for this is that the environment that most earwigs live in often prevents preservation, because dead organisms in soil and other crevices quickly rot and dissolve away.[3] It is known, however, that the sole fossil of it was found some time in the early 1900s by a team of Russian entomologists.[3]

Characteristics

Unlike its relative, Archidermapteron martynovi, Asiodiplatys speciousus had cerci, or rear appendages similar to antennae, that were less than the length of their abdomen.[4] By contrast, Archidermapteron martynovi had cerci that were not only longer than their abdomen, but longer than their abdomen and thorax combined.[5] The size of Asiodiplatys speciousus's cerci is much more similar to the cerci of modern-day earwigs, such as most male Common earwigs, or Forficula auricularia.[6]

However, the cerci of Asiodiplatys speciousus and Forficula auricularia differ greatly on one major front. Asiodiplatys speciousus had cerci that were more bead-like, or filiform, than the thicker cerci, specifically known as forceps, of most other earwigs.

Hemimerina, which are rare and contain few individuals.[7]

In order to open their wings, extant species of

Forficulina is probably not an adaptation for wing folding. Instead, it is likely that the cerci of Asiodiplatys speciousus served a function similar to that of an insect's antennae: a sense of touch.[3]

Phylogenesis

Forficulina
.

According to the research of Dr. Fabian Hass, an

Archidermapteron, Microdiplatys, and Protodiplatys.[11] He bases this assumption on the shape of the fossils' cerci: Archidermateron, Asiodiplatys, Microdiplatys, and Protodiplatys all had cerci that were long and filiform, while Dermapteron had cerci that were short and more forcep-like.[12]
Therefore, Turanovia would have been in between both groups.

However, this does not necessarily mean that Willmann's hypothesis is correct.[3] According to Dr. V. N. Vishnyakova, in an article written by her in the Paleontological Journal, Willmann could be correct on some fronts, but wrong on others.[13] Although Vishnyakova did not address Willmann specifically (she wrote about it ten years earlier), her paper disagrees with Willmann's on the basis of the ordering of Semenviola, Semenoviolides, and Turanoderma, which are extinct genera in Forficulina. Mainstream science is still unsure of whose chart is more accurate: it all depends on the definitions of certain taxon, which can change from person to person.[3]
