“…Dissection and illustration procedures follow Zilberman (2018), with adaptation on specimens mounting on slides, now with glycerin jelly. Terminology follows Jacobson et al (1986) for external and internal morphology and Sawada (1972) for chaetotaxy of sternite VIII, labrum and postmentum, with the following modification to postmentum chaetotaxy: although the three main bristles approached by Sawada were definitely present, it was not possible to have the homology inferred.…”

Fonsechellus Silvestri and Oecidiophilus Silvestri consist of two Neotropical genera of termitophilous rove beetles, which have been poorly characterized due to the scarcity of material for studies. Herein, based on material collected in the seventies and housed in the Museu de Zoologia da Universidade de São Paulo, two new species associated with Atlantitermes guarinim Fontes and Diversitermes sp., are described and illustrated: Fonsechellus heterosetosus sp. nov. and Oecidiophilus cleidecostae sp. nov., respectively. The latter represents the first record of the genus to Brazil. Also, Fonsechellus fragilis and F. fontesi are redescribed, and a key for species identification is provided for the genus. The condition of the membranous wings of Fonsechellus is addressed and discussed, and the definition of both genera is expanded.

“…Although presenting outstanding features to the study of symbiosis in general and termitophily in particular, C. cyphergaster studies regarding Corotoca spp. are still scarce, and most of them are focussed on taxonomy (see Seevers (1957); Jacobson and Pasteels (1985); Zilberman (2018)). In short, the biology of Corotoca is poorly understood, with many questions still open to investigation.…”

Mate finding in a mimetic termitophile amidst its host termites

The awesome variety of organisms using disguises to bypass harmful interactions readily reminds us that Darwin's "struggle for life" concept does not necessarily mean belligerence. Rather than engaging in open contests, these organisms negotiate their eco-evolutionary success copying animate or inanimate "models," thereby concealing themselves from, or deceiving, their potential contenders. The dupes are thence expected to develop ways to unmask their disguising counterparts (the "mimics") and that would set a disguisedetection arms race.The absence of overt hostility, however, does not rule out costs. Among these costs, one can be frequently overlooked:excess resemblance to the model may compromise intraspecific recognition for the mimic. Mimics could hence experience reduced fitness if their transparency affects mate encounters. This sounds particularly problematic for the interlopers of social insects who mimic hosts while obligatorily living and mating within the host nest. In such cases, the host functions as both a model and a dupe, convoluting arms races. Mimics, in their turn, face the need to recurrently balance social integration with the preservation of their own identity.Striking cases are provided by Staphylinidae beetles (Insecta: Coleoptera) closely resembling their ant and termite hosts (Howard et al., 1980;Maruyama & Parker, 2017). Among these, Corotoca spp. (Aleocharinae: Corotocini) are outstanding in morpho-chemical congruence to their termite hosts (Constrictotermes cyphergaster; Blattaria: Isoptera: Termitidae: Nasutitermitinae) and their

“…The search led Schiødte to confirm the viviparity in the three species, although in Spirachtha eurymedusa he found only embryos in the early stages of development. After Schiødte's description of C. melantho and C. phylo, other four species for the genus have been described so far: one species from Guyana, C. guyanae Mann, 1923; two from Brazil, C. araujoi Seevers, 1957, C. fontesi Zilberman, 2018 and one from Brazil and Argentina, C. pseudomelantho Zilberman, 2018(in Zilberman & Casari, 2018. Although none of these papers added knowledge about the viviparous condition of the genus, the phenomenon was often verified throughout history, including by the authors of this paper.…”

Viviparity is characterized by the retention of fertilized eggs in reproductive tract of the female. This condition is very common in vertebrates, but relatively rare in invertebrates, including insects. The present work presents a review on viviparity in Staphylinidae, with special attention on genus Corotoca Schiødte, 1853. The genus is composed by six termitophilous species with neotropical distribution, and together with Spirachtha Schiødte, 1853 are only two genera with species confirmed as viviparous in the family. Some other cases are only supposition. Also, it is presented information and discussion on the life cycle of Corotoca species based on dissection of females in laboratory and field observations. During the dissection of females of four species of Corotoca it was observed that each female carries three eggs at the same time. The embryos present asynchronous development: when one is located at apex of abdomen, the other two are at IV segment, on abdomen curvature. These observations are complementary with those obtained in field observation, when the female deposits a larva outside the nest, on the foraging trail of termite Constrictotermes cyphergaster (Silvestri, 1901). The strategy of Corotoca species focused on the immature as dispersing agent is derived and probably favor the fitnees in relation to a hypothetical condition in which the adult is the dispersive agent.
