Characterization of insect galls from a vegetation area in Altinópolis, São Paulo State, Brazil

Herein, we studied the occurrence of insect galls from natural vegetation around the Itambé Cave, Altinópolis, SP, Brazil. A sampling effort of 7.5 hours resulted in 41 gall morphotypes on 21 host plant species from 14 families. The richest families of host plants in morphotypes were Fabaceae (N = 11), Euphorbiaceae (N = 7), and Malpighiaceae (N = 5). Copaifera langsdorffii Desf. (N = 8), Croton floribundus Spreng. (N = 7), Diplopterys pubipetala (A. Juss.) W.R. Anderson & C.C. Davis (N = 5), and Bauhinia holophylla (Bong.) Steud. (N = 4) were the super host plant species. Among the gall makers obtained, cecidomyiids were reared in 81% of cases and Hemiptera (Diaspididae), Hymenoptera (Eurytomidae), Coleoptera (Apion sp./Apionidae), and Lepidoptera in 4.5% of cases, each. The parasitoids belong to the Chalcidoidea superfamily (Hymenoptera). One new species of Camptoneuromyiia (Cecidomyiidae) was found in Smilax oblongifolia Pohl ex Griseb. (Smilacaceae) as inquiline and a new species of Lestodiplosis in Diplopterys pubipetala (Malpighiaceae) was a predator. We also present the first register of Bauhinia holophylla as host plants of Cecidomyiidae. We also present the first register of Bauhinia holophylla as host plants of Cecidomyiidae, and we expand the occurrence of Rochadiplosis tibouchinae Tavares, Lopesia spinosa Maia and Couridiplosis vena Maia to São Paulo State. The results of this paper are a continuation of the description of gall morphotypes from the vegetation in Northeastern São Paulo State, and they also increase knowledge about the diversity of host plant and gall-maker associations in the Neotropical region.(AU)

Taxonomic revision and molecular phylogenetics of the Idarnes incertus species-group (Hymenoptera, Agaonidae, Sycophaginae).

Sycophaginae is a group of non-pollinating fig wasps considered closely related to the fig pollinators (Agaoninae, Tetrapusiinae, and Kradibiinae) in the most recent phylogenetic analyses. They occur in all tropical regions and are associated with Ficus subgenera Urostigma and Sycomorus. There are six described genera of Sycophaginae, and two are native and confined to the Neotropics, namely Idarnes Walker, 1843 and Anidarnes Boucek, 1993. Genus Idarnes is divided into three morphologically distinct groups that were proven to be monophyletic by recent molecular phylogenetic analyses. In this paper we reviewed the Idarnes incertus species-group and provide detailed morphological descriptions and illustrations for the species belonging to this group. Three previously described species were redescribed: I. brasiliensis (Mayr, 1906) comb. nov., I. hansoni Boucek, 1993, and I. incertus (Ashmead, 1900). Seventeen new species are described by Farache and Rasplus: I. amacayacuensissp. n., I. amazonicussp. n., I. americanaesp. n., I. badiovertexsp. n., I. brevissp. n., I. brunneussp. n., I. comptonisp. n., I. cremersiaesp. n., I. dimorphicussp. n., I. flavicrussp. n., I. flaviventrissp. n., I. gibberosussp. n., I. gordhisp. n., I. maximussp. n., I. nigriventrissp. n., I. pseudoflavussp. n. and I. ramirezisp. n. We provided keys for the identification of the species as well as for recognising the different species-groups of Idarnes and a closely related genus (Sycophaga Westwood, 1840). Additionally, phylogenetic relationships among 13 species of the I. incertus species-group were inferred using four molecular markers and discussed in the light of Ficus taxonomy and host specificity.

Conidarnes, a new oriental genus of Sycophaginae (Hymenoptera, Agaonidae) associated with Ficus section Conosycea (Moraceae).

The sycophagines are strictly associated with two subgenera of Ficus L. (Moraceae), namely Sycomorus and Urostigma. They mostly oviposit through the fig wall and lay their eggs within the fig flowers, being either gall-makers or parasitoids of other fig wasps. In this contribution, a new genus of Sycophaginae, Conidarnes Farache & Rasplus, gen. n., is described with seven new species: Conidarnes achterbergi Farache & Rasplus, sp. n.; Conidarnes bergi Farache & Rasplus, sp. n.; Conidarnes laevis Farache & Rasplus, sp. n.; Conidarnes santineloi Farache & Rasplus, sp. n.; Conidarnes subtectae Farache & Rasplus, sp. n.; Conidarnes sulcata Farache & Rasplus, sp. n.; and Conidarnes sumatranae Farache & Rasplus, sp. n. Illustrations, morphological diagnoses, dichotomous keys and multi-entry online keys to species are provided. Conidarnes species strictly occur in the oriental region, and their distribution does not overlap with the distribution of the two other genera belonging to the same clade. Due to their relative rarity, we encourage extensive sampling of Conosycea figs to improve our knowledge of the genus.

Thirty-six morphologically different types of galls were obtained in leaves, leaflets, veins, petioles, stems, tendrils and flower buds from twenty-five species of plants in the Pé-de-Gigante Reserve, municipality of Santa Rita do Passa Quatro, state of São Paulo, Brazil. The host plant species belong to the closely related families Anacardiaceae, Annonaceae, Asteraceae, Bignoniaceae, Caryocaraceae, Erythroxylaceae, Fabaceae, Malpighiaceae, Melastomataceae, Myrtaceae, Ochnaceae, Polygalaceae, Sapindaceae, Sapotaceae, and Smilacaceae.

Occurrence and characterization of entomogen galls in plants from natural vegetation areas in Delfinópolis, MG, Brazil

In the present work we aimed to register the occurrence of galls, inductors, inquilines, and parasitoids in plants of three natural vegetation areas in Delfinópolis, MG, Brazil. Results obtained showed 22 types of galls collected from leaf, vein leaf, petioles, stem, and inflorescence of nineteen species belonging to fifteen distinct families. Concerning gall morphology, the following were collected: globoid, conicle, discoidal, fusiform, shell-shape, indefinite, and one substituition of an ovary by an immature. As principal inducers were found insects of the families Cecidomyiidae (Diptera), Psyllidae, and Diaspididae (Sternorrhyncha/Hemiptera). As parasitoids the most common are of the Chalcidoidea superfamily (Hymenoptera) and, as occasional inquilines, Polyxenidae (Diplopoda) and Psocodea (Psocoptera). The results of this study contribute to existing of knowledge host-plant diversity and gall-associated insects in rocky fields, cerrado, and gallery forests.

Neste trabalho registramos a ocorrência de galhas, galhadores, inquilinos e parasitóides em plantas de três áreas de vegetação natural em Delfinópolis, MG, Brasil. Como resultado foram obtidas galhas coletadas em folhas, nervuras de folhas, pecíolos, ramos e inflorescências de quinze famílias distintas. Quanto à morfologia, foram coletadas galhas globóides, cônicas, discóides e fusiformes, em forma de concha, uma sem formato definido e uma substituição do ovário pelo imaturo. Como principais indutores foram obtidos insetos das famílias Cecidomyiidae (Diptera), Psyllidae e Diaspididae (Sternorrhyncha/Hemiptera). Os parasitóides são da superfamília Chalcidoidea (Hymenoptera) e, como inquilinos ocasionais, Polyxenidae (Diplopoda) e Psocodea (Psocoptera). Os resultados deste trabalho contribuem para aumento do conhecimento sobre a diversidade de plantas hospedeiras e insetos galhadores associados à vegetação de campo rupestre, cerrado e mata de galeria.
