Asiodiplatys speciousus had cerci that were more bead-like, or filiform, than the thicker cerci, specifically known as forceps, of most other earwigs.[3] From the fossil, it can be noted that Asiodiplatys speciousus's cerci were thin, almost identical to their antannae,[3] while Forficula auricularia's cerci are the opposite.[5] One of the key characteristics of the Forficulina suborder is the existence of large, thick, basally broadened and crenulate-toothed forceps, which is notably absent on Asiodiplatys speciousus. The only species of earwigs with these uncharacteristically-thinner cerci are earwigs in the suborders Arixeniina and Hemimerina, which are rare and contain few individuals.[6] In order to open their wings, extant species of Forficulina use their cerci because their wings fold into a "package" due to internal elasticity.[7] While Asiodiplatys speciousus had such a wing package, like other earwigs in the Archidermaptera suborder,[3] they also had long segmented cerci, as mentioned above. This means that the unsegmented cerci of 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] PhylogenesisAccording to the research of Dr. Fabian Hass, an entomologist who specializes in earwig biology,[8][9] the relative age of this species compared to other genera in the suborder Archidermaptera can be approximated based upon the research of Dr. R. Willmann.[10] According to Willmann, the genus Asiodiplatys, and therefore also the species Asiodiplatys speciousus, existed longer ago than the genera Dermapteron and Turanovia, but around the same time period as 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.[10] 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.[10] References1. ^{{cite web|title=Taxa display - Asiodiplatys speciousus |url=http://dermaptera.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=2873 |archiveurl=https://www.webcitation.org/5g6b6LvPQ?url=http://dermaptera.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=2873 |work=Dermaptera Species File |publisher=speciesfile.org |archivedate=2009-04-17 |accessdate=2009-04-17 |deadurl=no |df= }} 2. ^{{cite web|title=Taxa display - Asiodiplatys |url=http://dermaptera.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=2872 |archiveurl=https://www.webcitation.org/5g6bAxa7o?url=http://dermaptera.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=2872 |work=Dermaptera Species File |publisher=speciesfile.org |archivedate=2009-04-17 |accessdate=2009-04-17 |deadurl=no |df= }} 3. ^1 2 3 4 {{cite web|author=Dr. A.P.
