Abstract: The whip spider genus Sarax Simon, 1892 is widely distributed throughout Southeast Asia and part of the Indo-Malayan region. The genus is recorded from several Indonesian islands, but no species are known from inside the area that comprises the biogeographical region of Wallacea, despite being recorded from both sides of the area. An expedition to survey the biology of caves in Timor-Leste (formerly East-Timor) discovered populations of amblypygids living underground and including a remarkable new species of Sarax, S. timorensis sp. n., the first Amblypygi known from the island of Timor. The new species is here described bears the unique character state of two pairs of lateral eyes, instead of three or none as in all other living species of Amblypygi, and expands the biogeographic range of the genus. New records of amblypygids are given for two caves in Timor-Leste. A detailed description and a discussion of its distribution and the species characters are also provided.

A new species of Charinus Simon 1892 from Brazil, with notes on behavior (Amblypygi, Charinidae) https://zookeys.pensoft.net/article/9980/ ZooKeys 621: 15-36

DOI: 10.3897/zookeys.621.9980

Authors: Gustavo Miranda, Milena Milleri-Pinto, Thiago Gonçalves-Souza, Alessandro Giupponi, Nikolaj Scharff

Abstract: A new species of Charinus is described and illustrated from the Brazilian Atlantic Forest. Charinus ruschii sp. n. is found in Santa Lúcia reserve, Espírito Santo state, and is sympatric with C. brasilianus and C. montanus. The new species can be easily distinguished from the other species of the genus by the combination of the following characters: number of spines on the pedipalp tarsus, size and shape of the female genitalia, shape of the sternum and number of teeth in the cheliceral claw. The behavioral repertory is also described for this species based on five hours of qualitative and 24 hours of quantitative observations in order to define the behavioral categories. Five behavioral categories were detected and 21 behavioral acts. The most conspicuous category was Immobility, followed by Antenniform leg movement, Environmental exploration, Self-grooming, and Feeding. It was also found that juveniles spend longer time inside the shelter, even during peaks of adult activity, which could be related to a survival strategy.

Description of a new troglomorphic species of Charinus Simon, 1892 from Brazil (Arachnida, Amblypygi, Charinidae) https://zookeys.pensoft.net/article/8580/ ZooKeys 600: 35-52

DOI: 10.3897/zookeys.600.8580

Authors: Ana Caroline Oliveira Vasconcelos, Alessandro Ponce de Leão Giupponi, Rodrigo Lopes Ferreira

Abstract: Charinus taboa sp. n. comprises the twenty-second species of the genus described for Brazil. The new species belongs to the eastern Brazilian group, in which all species have sucker-like gonopods. Charinus taboa sp. n. has a marked sexual dimorphism in the pedipalps as do other members of the genus in the country. The description of Charinus taboa sp. n. offers an opportunity to discuss some aspects of ecology, troglomorphism and conservation within the genus. A key to the eastern Brazilian species of Charinus is provided.

Interaction of the tracheal tubules of Scutigera coleoptrata (Chilopoda, Notostigmophora) with glandular structures of the pericardial septum https://zookeys.pensoft.net/article/5540/ ZooKeys 510: 233-242

DOI: 10.3897/zookeys.510.8644

Abstract: Notostigmophora (Scutigeromorpha) exhibit a special tracheal system compared to other Chilopoda. The unpaired spiracles are localized medially on the long tergites and open into a wide atrium from which hundreds of tracheal tubules originate and extend into the pericardial sinus. Previous investigators reported that the tracheal tubules float freely in the hemolymph. However, here we show for the first time that the tracheal tubules are anchored to a part of the pericardial septum. Another novel finding is this part of the pericardial septum is structured as an aggregated gland on the basis of its specialized epithelium being formed by hundreds of oligocellular glands. It remains unclear whether the pericardial septum has a differently structure in areas that lack a connection with tracheal tubules. The tracheal tubules come into direct contact with the canal cells of the glands that presumably secrete mucous substances covering the entire luminal cuticle of the tracheal tubules. Connections between tracheae and glands have not been observed in any other arthropods.
