“…The feeding on pith parenchyma and the consequent overdifferentiation of new cells are not exclusive aspects of E. minutanus and have been reported for Tortrimosaica polypodivora Brown & Baixeras, 2004 (Lepidoptera: Tortricidae) feeding on Microgramma squamulosa (Kaulf.) de la Sota (Polypodiaceae) (Kraus et al, 1993; Brown et al, 2004; Santos et al, 2019). Plant cells that redifferentiate, such as those of parenchyma and pericycle in galls induced by E. minutanus and the phellogen of galls from C. eremita galls, are very responsive to the stimuli of galling herbivores, especially in young stems (Barnewall and De Clerk‐Floate, 2012; Dias et al, 2013a; Ferreira and Isaias, 2013; Ferreira et al, 2019), and are highly involved in cell, tissue, and organ neoformation during the induction and development of their globoid gall morphotypes.…”

Premise Gall‐inducing organisms change the development of their host plant organs, resulting in ontogenetic patterns not observed in the non‐galled plants. Distinct taxa induce galls on Schinus spp., manipulating meristematic patterns in the host plant in distinct ways. Here we report ontogenetic novelties induced in the lateral buds of S. engleri by Eucecidoses minutanus, a Cecidosidae, whose galls have been poorly understood. Methods The anatomy, histochemistry, and histometry of galls in distinct phases of development, non‐galled buds, and stems of Schinus engleri were analyzed in parallel with the instars of E. minutanus to detail the morphogenetic changes in the host with each larval stage. Results Ontogenetic phases of the galls were intricately associated with larval development. First and second‐instar larvae induced pericycle and pith cells to dedifferentiate into the gall inner meristem, where hyperplasia and cell hypertrophy characterized the growth and development phase of the gall. The innermost layers were lipid‐rich nutritive cells that lined the larval chamber. Additional vascular bundle rows were produced in young galls. Third and fourth instar‐larvae were associated with the gall maturation phase: centripetal lignification of the outer parenchyma cell layers, epidermal stratification, and activation of a cambium‐like meristem (CLM). The CLM activity resulted in new layers of nutritive cells that differentiated inward as the first layers of nutritive cells were consumed by E. minutanus larvae, and, also, in more parenchyma cell layers that formed outward. All tissues between the innermost layer of nutritive tissue that surround the gall chamber and the outermost layer of the dermal system that externally covers the gall form the gall wall, and increased in thickness until the end of gall maturation. Conclusions E. minutanus induces a structurally complex globoid stem gall, modifying all host plant tissues and stimulating a novel meristematic pattern in S. engleri. The gall developmental stages are each related to specific gall‐inducing instars, as gall development progresses according to the development of E. minutanus.

The taxonomic boundaries of many Neotropical ant species of the genus Tapinoma are still unclear. Tapinoma atriceps and T. atriceps breviscapum are two morphologically similar taxa which occur sympatrically in the southern Atlantic Forest of Brazil. Some characters such as the scape length and head shape suggest that these taxa may be different species. We used DNA analysis and morphological evidence, including scanning electron microscopy, to evaluate the taxonomic validity of these taxa. We found distinct morphological characteristics that allow separating them as two different species, Tapinoma atriceps and Tapinoma breviscapumstatus novo, and this decision is supported by the DNA results, where Tapinoma atriceps was recovered as a lineage independent of T. breviscapum.

“…These new habitats might persist on plants and can be later used as shelter by other arthropods in a facilitative interaction process (Vieira and Romero 2013, Cornelissen et al 2016, Zuo et al 2016, Novais et al 2018). Particularly, ants can take advantage of the abandoned shelters made by other insects for nesting, such as wood‐boring beetle abandoned cavities (Tschinkel 2002, Satoh et al 2016, Novais et al 2017), senescent galls (Fernandes et al 1988, Mehltreter et al 2003, Almeida et al 2014, Santos et al 2017, 2019), and empty cocoons (Raath et al 2017).…”

Arthropod facilitation mediated by abandoned dead domatia

et al. 2021

In ant-plant mutualistic interactions, plants provide shelter (domatia) and/or food to ants and in exchange, and ants provide protection against herbivores. After plant tissue senescence, ants are expected to abandon dead domatia, leaving these empty spaces available for other arthropods. In this study, we tested for the role of the mutualistic interaction between Cordia alliodora and Azteca pittieri in promoting new habitats for arthropods through abandoned dead domatia. We predicted that species richness, abundance, and colonization frequency of secondary arthropods would be greater in dead branch domatia (dead domatia) compared with live branch domatia (live domatia). During March 2019, we selected 38 C. alliodora trees in a Mexican tropical dry forest. For each tree, we collected five live and five dead domatia, for 380 domatia in total. We found six morphospecies of secondary arthropods colonizing live domatia, while 42 were present in dead domatia. Ants were the most species-rich group (10 species) in abandoned dead domatia and utilized them as nesting sites (25 nests). Secondary arthropod species richness, abundance, and colonization frequency were greater in dead domatia compared with live domatia. We concluded that the Azteca-Cordia mutualistic interaction is an important habitat facilitator by promoting new habitats for arthropods through abandoned dead domatia.
