“…They are apparently relatively common and widespread in the Neotropics, all associated with galls, occurring in several plant families including Burseraceae, Fabaceae, Melastomataceae, Polygonaceae, Rubiaceae, and Solanaceae (e.g., Macedo and Monteiro 1989, Marsh et al 2000, Marsh 2002, Penteado-Dias and Carvalho 2008, Chavarría et al 2009, Centrella and Shaw 2010, 2013, Martínez et al 2011, Martínez and Zaldívar-Riverón 2013). However, their biology is largely unknown, and it is still uncertain whether they are primary gall inducers or inquilines.…”

Galls induced by the larval stage of cecidosids (Lepidoptera: Cecidosidae) are complex, multi-trophic systems, still poorly studied. They may be associated with other insect feeding guilds, including inquilines, kleptoparasites, cecidophages, parasitoids, and predators. By causing death of the gall inducer early in life and altering the gall phenotype, inquilines may lead to misidentification of the true gall inducers. Here, we describe through light and scanning electron microscopy Cecidonius pampeanus, a new genus and species of cecidosid moth, from the Pampa biome, south Brazil. It induces unnoticed, small galls under swollen stems of Schinus weinmannifolius Mart. ex Engl. (Anacardiaceae). Such galls are severely attacked early in ontogeny either by unidentified parasitoids belonging to Lyrcus Walker (Pteromalidae) that feed upon the inducer, or by inquiline wasps of the genus Allorhogas Gahan (Braconidae). The inquilines modify the galls into large ones that last longer and promptly call attention. Free-living galls are rare and dehiscent, pupation of C. pampeanus occurring on the ground. Due to these reasons the true inducer has been overlooked in this case for more than a century. Additionally we inferred a phylogeny for Cecidosidae using sequences from mitochondrial and nuclear loci, and characterized genetic variation and gene flow across ten populations. Despite its natural history similarities with the African genus Scyrotis, Cecidonius is a much younger lineage, more closely related to the Neotropical cecidosids. C. pampeanus populations, which are now confined to a few mountain areas within its distribution range due to habitat destruction, are also genetically isolated, requiring conservation measures.

“…Allorhogas is one of the most speciose doryctine genera in the Neotropics perhaps only after Heterospilus and Notiospathius . This neglected genus is currently receiving more attention, and several new species have been described during the last decade (Martínez et al , ; Penteado‐Dias & de Carvalho, ; Chavarría et al , ; Centrella & Shaw, , ; Martínez et al , ; Martínez & Zaldívar‐Riverón, ).

Gall formation is a specialised form of phytophagy that consists of abnormal growth of host plant tissue induced by other organisms, principally insects and mites. In the mainly parasitoid wasp subfamily Doryctinae, gall association, represented by gall inducers, inquilines and their parasitoids, is known for species of seven genera. Previous molecular studies recovered few species of six of these genera as monophyletic despite their disparate morphologies. Here, we reconstructed the evolutionary relationships among 47 species belonging to six gall‐associated doryctine genera based on two mitochondrial and two nuclear gene markers. Most of the Bayesian analyses, performed with different levels of incomplete taxa and characters, supported the monophyly of gall‐associated doryctines, with Heterospilus (Heterospilini) as sister group. Percnobracon Kieffer and Jörgensen and Monitoriella Hedqvist were consistently recovered as monophyletic, and the validity of the monotypic Mononeuron was confirmed with respect to Allorhogas Gahan. A nonmonophyletic Allorhogas was recovered, although without significant support. The relationships obtained and the gathered morphological and biological information led us to erect three new genera originally assigned to Psenobolus: Ficobolus gen.n. (F. paniaguai sp.n. and F. jaliscoi sp.n.), Plesiopsenobolus gen.n. (Pl. mesoamericanus sp.n., Pl. plesiomorphus van Achterberg and Marsh comb.n., and Pl. tico sp.n.), and Sabinita gen.n. (S. mexicana sp.n.). The origin of the gall‐associated doryctine clade was estimated to have occurred during the middle Miocene to early Oligocene, 16.33–30.55 Ma. Our results support the origin of true gall induction in the Doryctinae from parasitoidism of other gall‐forming insects. Moreover, adaptations to attack different gall‐forming taxa on various unrelated plant families probably triggered species diversification in the main Allorhogas clade and may also have promoted the independent origin of gall formation on at least three plant groups. Species diversification in the remaining doryctine taxa was probably a result of host shifts within a particular plant taxon and shifts to different plant organs.

“…Phytophagous braconids primarily produce galls on stems and fruits, from feeding on seeds or fruits, and feed on species of Araceae, Burseraceae, Fabaceae, Melastomataceae, Mimosaceae, Moraceae, Proteaceae, Rubiaceae and Solanaceae. The phytophagic life strategy occurs primarily in the Neotropics, in species of Allorhogas, Bracon, Monitoriella and Psenobolus (Marsh, 1991, Infante et al 1995, Ramirez and Marsh 1996, Marsh et al 2000, Marsh 2002, Flores et al 2005, Centrella and Shaw 2010, Martinez et al 2011, Perioto et al 2011, Shimbori et al 2011, Centrella and Shaw 2013. The number of potential phytophagous species collected in the RLBR are represented in 75% of the genera known with this biological trait and indicate a future need to determine the interactions between host plants and phytophagous braconids, its abundance and its role in the vegetation composition.…”

The species diversity composition and phenological behaviour of four braconid subfamilies (Hymenoptera: Braconidae: Agathidinae, Braconinae, Doryctinae and Macrocentrinae) were monitored in three vegetation communities (dune vegetation, tropical deciduous forest and savannah) of the Ria Lagartos Biosphere Reserve (RLBR) in Yucatan, Mexico. Braconid wasps were collected with Malaise traps every 15 days over one year (June 2008 to June 2009). A total of 2,476 specimens were inventoried comprising 233 species and 63 genera. The composition of braconids and their lifestyles differed among the three vegetation communities studied. Doryctinae was the most diverse and abundant subfamily in RLBR (40 genera, 145 species, 990 specimens) and the tropical deciduous forest recorded the maximum abundance and diversity (H’= 4.1; alpha value= 1.059), with 61 exclusive species. Phenological sequence indicates an influence of the rainy season in braconid diversity, but its effects differed among braconid subfamilies and among the vegetation communities. Finally, the importance of the RBRL as a conservation site for this hymenopterous wasp is discussed.
