Chemical acaricides such as permethrins and fipronil, widely used in veterinary medicine for mite and tick control, are contraindicated in scorpions. Since mites and scorpions both belong to the class Arachnida, even minimal exposure can result in severe toxicity or death. Neem oil ( Azadirachta indica ) has been widely recognized for its acaricidal, antibacterial, and antifungal properties. Its main compound, azadirachtin, interferes with mite development and reproduction, leading to reduced infestations and egg viability. This study evaluated the efficacy and safety of a 1...

On Some Rare Mygalomorph from Ecuador, with the Description of 16 New Species in Five Families (Mygalomorphae: Actinopodidae, Barychelidae, Halonoproctidae, Idiopidae, and Theraphosidae)

Abstract

This study on Mygalomorphs from Ecuador revealed an amazing unknown diversity, including the first record of the families Actinopodidae and Halonoproctidae. Here, 16 new species and one new genus are described in five families: in Actinopodidae, Actinopus saraguro n. sp. (♀); in Barychelidae, Paracenobiopelma vesca n. sp. (♀), Strophaeus pacificanus n. sp. (♀), S. real n. sp. (♀), S. elongata n. sp. (♂♀), S. josefita n. sp. (♂♀), S. peronii n. sp. (♂♀), S. kaiae n. sp. (♀), S. subterraneus n. sp. (♂), S. spiculum n. sp. (♂), and S. kawsay n. sp. (♀); in Halonoproctidae, Ummidia pupulae n. sp. (♂); in Idiopidae, Idiops clepsydra n. sp. (♀); and in Theraphosidae, Pululahua gen. n., Pululahua kunukyaku gen. n., n. sp. (♂♀), and Pululahua winku gen. n., n. sp. (♂♀); and Thalerommata yasuni n. sp. (♂). Furthermore, images of the type specimens of Actinopus nattereri (Doleschall, 1871) and Actinopus piceus (Ausserer, 1871) are presented. Finally, the synonymy of Idiops fulvipes under Idiops argus is rejected.
