Petrolisthes
porcelain crabs
Petrolisthes is a genus of marine porcelain crabs in the family Porcellanidae, containing approximately 50 extant species distributed across temperate and tropical coastal regions of the Pacific Rim and warm Western Atlantic. These small, flattened crabs occupy intertidal and subtidal zones, often forming dense aggregations under rocks and within crevices. Multiple species have been subject to intensive behavioral and ecological study, revealing complex patterns of intraspecific competition, thermal adaptation, and settlement behavior. Two species (P. cinctipes and P. manimaculis) have been sequenced, providing genomic resources for studying physiological responses to climate change.
Quesada gigas
Giant cicada, chichara grande, coyoyo, coyuyo, coffee cicada
Quesada gigas is a large cicada species native to North, Central, and South America, with the widest geographic range of any cicada in the Western Hemisphere. It is a significant agricultural pest, particularly of coffee (Coffea) in Brazil and paricá (Schizolobium parahyba var. amazonicum) in the Amazon region, where nymphal feeding on roots can cause substantial yield losses or tree mortality. The species exhibits low selectivity in oviposition site choice, with females documented laying eggs in dry branches of non-host plants such as Conyza spp. weeds, which cannot support complete nymphal development due to their annual life cycle.
