“…The new classification of Dermaptera proposed by Engel and Haas (2007) placed four families (Forficulidae, Spongiphoridae, Arixeniidae, and Chelisochidae) as part of a superfamily Forficuloidea. It is clear that Forificuloidea is not monophyletic based on this analysis, confirming suspicions of paraphyly for this group based on a series of morphological characters associated with ovariole structure (Bilinski et al, 2014). Our work supports the monophyly of Forificulidae and Chelisochidae, but the remaining free-living families appear paraphyletic.…”

Dermaptera is a relatively small order of free-living insects that typically feed on detritus and other plant material. However, two earwig lineages - Arixeniidae and Hemimeridae - are epizoic on Cheiromeles bats and Beamys and Cricetomys rats respectively. Both of these epizoic families are comprised of viviparous species. The monophyly of these epizoic lineages and their placement within dermapteran phylogeny has remained unclear. A phylogenetic analyses was performed on a diverse sample of 47 earwig taxa for five loci (18S rDNA, 28S rDNA, COI, Histone 3, and Tubulin Alpha I). Our results support two independent origins of the epizoic lifestyle within Dermaptera, with Hemimeridae and Arixeniidae each derived from a different lineage of Spongiphoridae. Our analyses places Marava, a genus of spongiphorids that includes free-living but viviparous earwigs, as sister group to Arixeniidae, suggesting that viviparity evolved prior to the shift to the epizoic lifestyle. Additionally, our results support the monophyly of Forficulidae and Chelisochidae and the paraphyly of Labiduridae, Pygidicranidae, Spongiphoridae, and Anisolabididae.

“…semiflavus, ovarioles are greatly shortened and contain only one developing egg in the basal-most part at a time. Similar conditions were reported for C. borneensis (Bilinski et al 2014). For M. arachidis, Ramamurthi (1956) reported that each ovary has a single ovariole.…”

“…semiflavus and C. borneensis (Y. K., unpublished data). Bilinski et al (2014) found the opposite ovarian structure (i.e., longer ovarioles attached to shorter lateral oviducts) in Irdex chapmani Brindle, 1980 (Spongiphoridae: Spongiphorinae). The discovery of C. borneensis-type ovaries in two ovoviviparous spongiphorine earwigs strongly supports their apparent adaptation for the retention of large-sized eggs and ovarian fertilization, similar to a specialized lateral oviduct wall for the passing of large, fully developed eggs (Tworzydlo 2015).…”

Ovoviviparity and viviparity have evolved independently multiple times in animals. Although females exhibit extensive parental care of their eggs, (ovo)viviparity has only been reported in a few species of free-living, nonepizoic earwigs. In contrast, to date, all the studied members of families Arixeniidae and Hemimeridae, which live on mammals, are viviparous. We herein report ovoviviparity in the tropical earwig species, Spongovostox semiflavus (Bormans, 1894) (Forficuloidea: Spongiphoridae: Spongiphorinae). We observed that females of this species retain well-developed embryos within the ovaries and then lay them with complete egg envelopes just before hatching. An average of 9.4 embryos concurrently developed in a female's body. A similar condition has been reported for only one other species Marava arachidis (Yarsin, 1860), in the subfamily Spongiphorinae. Without additional mating, Spo. semiflavus females produced at least three clutches, consisting of an average of nine offspring within a period of 14-27 d. Both Spo. semiflavus and M. arachidis males are characterized by elongated male genitalia that are more than twice as long as their body lengths. Interestingly, elongated male genitalia are also present in the two other spongiphorids for which (ovo)viviparity has been reported. We discuss the causes of the potential convergence of the evolution of the male genital structure and the development of (ovo)viviparity in females.
