Ami, a new Theraphosid genus from Central and South America, with the description of six new species (Araneae: Mygalomorphae)

Abstract

A new genus Ami Pérez-Miles is proposed for six new species: A. caxiuana Pérez-Miles, Miglio & Bonaldo, from Caxiuanã National Forest, Pará, Brasil, the type species; A. yupanquii Pérez-Miles, Gabriel & Gallon, from the area of Puyo, Equador; A. bladesi Pérez-Miles, Gabriel & Gallon, from Isla Colón, Panamá; A. pijaos Jimenez & Bertani, from Ibagué, Tolima, Colombia; A. amazonica Jimenez & Bertani, from Leticia, Amazonas, Colombia; and A. weinmanni PérezMiles, from La Azulita, Apure, Venezuela. Avicularia obscura (Ausserer 1875) is transferred to Ami and re-diagnosed. Diagnostic characters of Ami are the modification of Type I urticating hairs, with unusually longer area b, and one or two subconical processes on retrolateral face of male palpal tibiae. Females of Ami differ further from those of other theraphosid genera by their highly characteristic spermathecae: paired ventral receptacles attached to an almost discrete, semicircular, sclerotized back-plate.

Jambu, a new genus of tarantula from Brazil (Araneae, Theraphosidae, Theraphosinae)

“…Palpal bulb terminology follows Bertani (2000), Fukushima et al (2005) and Fonseca-Ferreira et al (2017). Spination description follows Pérez-Miles et al (2008); leg scopula is described as proposed by Pérez-Miles (1994); tibial apophysis are described following Perafán & Pérez-Miles (2014); and urticating setae following Cooke et al (1972) and Bertani & Guadanucci (2013)…”

On three newEuathlustarantulas from Argentina and cladistic analysis of the genus

“…Terminology for tibial apophyses (or spurs) follows the general usage in Theraphosidae. It includes the prolateral apophysis (or apophysis branch) and retrolateral apophysis (e.g., Bertani 2001;Pe ´rez-Miles et al 2008). Spine notation follows Petrunkevitch (1925).…”

Four new species of mygalomorph spiders (Araneae, Halonoproctidae and Theraphosidae) from the Colombian Pacific region (Bahía Solano, Chocó)

“…Urticating setae: types I urticating setae present, subtype I c ( Kaderka et al 2019 ) and I modified ( Pérez-Miles et al 2008 ) / subtype I d ( Kaderka et al 2019 ), located in a dorsoposterior abdominal patch; with a clearly higher proportion of urticating setae subtype I d (100:1).…”
