Species-specific ant resemblance in heteronotine membracids (Hemiptera: Membracidae) is reported for the first time, providing evidence for ant mimicry. The shape, integument color and shine of the pronotal process of females of Heteronotus fabulosus Boulard closely resemble workers of the cooccurring giant turtle ant Cephalotes atratus (Linnaeus) (Hymenoptera: Formicidae). The entire membracid appears to mimic a mutualistic relationship between a membracid and a turtle ant.

A new species of ant-mimicking spider of the subfamily Castianeirinae, Myrmecotypus rubrofemoratus Perger and Rubio, new species (Araneae: Corinnidae), is described from the Pre-Andean area of the Bolivian orocline. Adults of M. rubrofemoratus new species resemble the carpenter ant Camponotus femoratus Forel, 1907, which is considered one of the most aggressive ants in the world.
