“…Twelve characters for female individuals and eleven characters for males were analyzed. Cephalic size (CS) is considered to be a fair indicator of overall body size in ants (Seifert, 2002;Cső sz et al, 2007), hence (CS) was used as covariate. Parasitogenic phenotypes and uninfected individuals of females and males were compared in two independent analyses.…”

Entomo-pathogen parasites typically induce alternative "parasitogenic" phenotypes in ants and other insects. However, the basis of generated developmental changes is poorly understood. Parasitic mermithid nematodes also cause the formation of three discrete and aberrant morphologies within Myrmica ants. These have been called "worker-like" ("mermithergate"), "intermorphic" ("gynaecoid mermithergate") and "gyne-like" ("mermithogyne") and their formation has been attributed to infection of worker-and queen-presumptive larvae, respectively. In order to better understand the developmental mechanisms that lead to the formation of these alternative parasitogenic phenotypes we observed allometric patterns of parasitogenic Myrmica gallienii phenotypes in comparison with uninfected workers and gynes from the same nests. It was revealed that the three discrete morphologies of parasitogenic female phenotypes did not differ significantly from each other in their scaling indicating that these were trapped in the same developmental pathway. Infected individuals scaled according to basically gyne-like allometry, however significantly differed from workers in their scaling. Based on the observed scaling patterns we herein raise an alternative explanation according to which both "mermithergate", "gynaecoid mermithergate" and "mermithogyne" Myrmica phenotypes develop from the same type of larvae, namely from the queen-presumptive larvae and their formation, therefore, is rendered as a diverging process. According to the mechanism we propose effect of nematodes may turn out to be the determining factor in the formation of alternative parasitogenic morphologies.

“…Several of the names are poorly known, have not been revised since the original description, and are considered to be incertae sedis. Only Tetramorium chefketi and Tetramorium ferox groups have been recently revised and six other species have been lately redescribed in detail (Csösz and Markó 2004, Güsten et al 2006, Csösz et al 2007, 2014, Csösz and Schulz 2010, Steiner et al 2010, Borowiec and Salata 2014, Espadaler and Goméz 2014) and molecular data suggests that some widely distributed species represent groups of cryptic taxa (Schlick-Steiner et al 2006). …”

What is Tetramorium semilaeve André, 1883? (Hymenoptera, Formicidae)

Tetramorium semilaeve André, 1883 is redescribed based on the type series and new material from terra typica (Pyrénées-Orientales). Lectotype worker is designated. Detailed descriptions of gyne and male are given. A review of material from the Mediterranean area suggests that in the past the name Tetramorium semilaeve has been applied to more than one species and the true Tetramorium semilaeve is common only in the western part of the Mediterranean basin. The structure of the male genitalia is the most reliable set of characters allowing a proper distinction of species in Tetramorium semilaeve species group. All names attributed to the former name “semilaeve” are discussed.

“…These works provided an excellent foundation for the many later revisions or treatments of species groups/complexes or regions/subregions (e.g. Csösz et al 2007; Csösz and Schulz 2010; Hita Garcia et al 2010; Hita Garcia and Fisher 2011, 2012a, 2012b, 2013, 2014a, 2014b; Bharti and Kumar 2012; Sharaf et al 2012; Vásquez Bolaños et al 2011). The Malagasy Tetramorium fauna was first monographed by Bolton (1979), who treated eight species groups with 36 species (29 of these endemic to Madagascar).…”

In this study we provide an update to the taxonomy of the ant genus Tetramorium Mayr in Madagascar. We report the first record of the Tetramorium setigerum species group in Madagascar and describe the only Malagasy representative as Tetramorium cavernicola sp. n., which is known only from a cave in Ankarana. In addition, we provide an overview of the 19 proposed Malagasy species groups, and discuss their zoogeography and relationships to other groups and larger lineages within the hyper-diverse genus Tetramorium. At present, we recognise a highly unique Malagasy Tetramorium fauna with 113 species endemic to the island of Madagascar out of a total of 125 translating into an endemism rate of 93%. We hypothesise that this fauna is based on one or a few colonisation events from the Afrotropical region, with subsequent adaptive radiation in Madagascar. Furthermore, we present an updated and illustrated identification key to the Tetramorium species groups in the Malagasy region.
