[i]Conidames[/i], a new oriental genus of Sycophaginae (Hymenoptera, Agaonidae) associated with [i]Ficus[/i] section Conosycea (Moraceae)

The sycophagines are strictly associated with two subgenera of Fit to L. (Moraceae), namely,Slycomo77/S and Urostignza. 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, [i]Conidarnes[/i] Earache & Rasplus, gen. n., is described with seven new species: [i]Conidarnes achterbergi[/i] Earache & Rasplus, sp. n.; [i]Conidarwes beryl'[/i] Farache & Rasplus, sp. n.; [i]Conidarnes laevis[/i] Earache & Rasplus, sp. n.;[i] Conidames santineloi[/i] Earache & Rasplus, sp. n.; [i]Conidarnes subtectae[/i] Earache & Rasplus, sp. n.; [i]Conidarnes sidcata[/i] Farache & Rasplus, sp. n.; and [i]Conidarnes sumatranae[/i] Farache & Rasplus, sp. n. Illustrations, morphological diagnoses, dichotomous keys and multi-entry online keys to species are provided. [i]Conidarnes[/i] 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

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Revision of the Australasian genus <em>Pseudidarnes</em> Girault, 1927 (Hymenoptera, Agaonidae, Sycophaginae)

International audienceThe species of Pseudidarnes are revised, and six species are described: P. acaudus Farache & Rasplus, sp. n.; P. astridae Farache & Rasplus, sp. n.; P. badiogeminus Farache & Rasplus, sp. n.; P. cooki Farache & Rasplus, sp. n.; P. kjellbergi Farache & Rasplus, sp. n.; P. laevis Farache & Rasplus, sp. n. Pseudidarnes minerva Girault, 1927 and P. flavicollis Boucek, 1988 are redescribed. A key to the species is provided as well as illustrations for all females and all known males (except the wingless male of P. minerva). We also provided further discussion on ecology, morphological patterns, and host taxonomy. Online dichotomous and multi-access interactive LUCID keys to all Pseudidarnes species are available at http://www.figweb.org/

Ovipositor morphology correlates with life history evolution in agaonid fig wasps

International audienceThe high adaptive success of parasitic Hymenoptera might be related to the use of different oviposition sites, allowing niche partitioning among co-occurring species resulting in life history specialization and diversification. In this scenario, evolutionary changes in life history and resources for oviposition can be associated with changes in ovipositor structure, allowing exploitation of different substrates for oviposition. We used a formal phylogenetic framework to investigate the evolution of ovipositor morphology and life history in agaonid wasps. We sampled 24 species with different life histories belonging to all main clades of Agaonidae including representatives of all described genera of non-pollinating fig wasps (NPFW). Our results show an overall correlation between ovipositor morphology and life history in agaonid fig wasps. Ovipositor morphologies seem to be related to constraints imposed by features of the oviposition sites since ovipositor morphology has experienced convergent evolution at least four times in Sycophaginae (Agaonidae) according to the resource used. Nongalling species have more distantly spaced teeth with uneven spacing, as opposed to the observed morphology of galling species. Our results suggest that the ancestral condition for ovipositor morphology was most likely the presence of one or two apical teeth. Regarding life history, ovary galling species that oviposit in receptive figs possibly represent the ancestral condition. Different ovipositor characteristics allow exploitation of new niches and may be related to resource partitioning and species coexistence in the fig-fig wasp system

The unknown followers: Discovery of a new species of Sycobia Walker (Hymenoptera: Epichrysomallinae) associated with Ficus benjamina L. (Moraceae) in the Neotropical region

International audienceBiotic invasion in mutualistic communities is of particular interest due to the possible establishment of new relationships with native species. Ficus species are widely cultivated as ornamental plants, and they host specific communities of chalcid wasps that are strictly associated with the fig inflorescences. Some introduced fig species are capable of establishing new relationships with the local fig wasps, and fig wasp species may also be concomitantly introduced with their host plants. Ficus benjamina L. is widely cultivated across the world, but the associated fig wasps are not reported outside of the species native range. We describe for the first time a non-pollinating fig wasp associated with E benjamina inflorescences outside its native distribution. Sycobia hodites Farache & Rasplus, sp. n. is the third known species of the genus and was recorded in populations of E benjamina introduced in the Neotropical region throughout several localities in Argentina, Brazil and Colombia. Sycobia is a gall-inducing non-pollinating fig wasp genus associated with fig trees in the Oriental and Australasian regions. This species competes with pollinators for oviposition sites and may hinder the future establishment of the native pollinator of E benjamina, Eupristina koningsbergeri Grandi, 1916 in the New World. However, the occurrence of a gall inducing species in this host plant may open ecological opportunities for the establishment of species belonging to other trophic levels such as cleptoparasite and parasitoid wasps
