“…The family Ammotrechidae Roewer, 1934 occupies the third position in terms of generic diversity within Solifugae, only outrun by Daesiidae and Rhagodidae (Harvey 2003;Iuri et al 2021). This family is currently divided into five subfamilies: Ammotrechinae Roewer, 1934, Mortolinae Mello-Leitão, 1938, Nothopuginae Maury, 1976, Oltacolinae Roewer, 1934, and Saronominae Roewer, 1934.…”

“…Most of its generic diversity is contained in Ammotrechinae and Saronominae, respectively with ten and five genera (Harvey 2003). Mortolinae and Nothopuginae, as recently redefined (see Iuri et al 2021), comprise three genera each, whereas Oltacolinae has remained monogeneric. Until recently, the internal classification of Ammotrechidae was devoid of any phylogenetic structure.…”

“…Until recently, the internal classification of Ammotrechidae was devoid of any phylogenetic structure. Iuri et al (2021) presented the first phylogenetic analysis of the family, wherein some changes to the traditional classification scheme were presented and some important characters were addressed. That work also presented, for the first time, evidence in support of the monophyly of Ammotrechidae and of three of its subfamilies (Mortolinae, Nothopuginae, Oltacolinae).…”

“…For several years, three genera, Chileotrecha Maury, 1987, Eutrecha Maury, 1982, and Xenotrecha Maury, 1982, have remained unclassified within Ammotrechidae (Harvey 2003) -not counting the extinct Happlodontus Poinar and Santiago-Blay, 1989 which will not be addressed here. Iuri et al (2021) proposed that all three belong to a large clade consisting of Ammotrechinae + Saronominae, but they failed to assign them to either of the two subfamilies. Xenotrecha is a monotypic genus, consisting only of its type species, Xenotrecha huebneri (Kraepelin, 1899), and is known by a handful of specimens from Venezuela and Brazil (Maury 1982;Rocha and Cancello 2002).…”

“…Ammotrechinae, the nominotypical subfamily of Ammotrechidae, was proposed in the monumental work of Roewer (1934). It currently comprises ten extant genera, whereas eleven others and the extinct Happlodontus are sorted to other subfamilies or remain unclassified (Harvey 2003;Iuri et al 2021). Up until the recent work of Iuri et al (2021), no efforts had attempted to test the monophyly of Ammotrechinae or evaluated the phylogenetic position of its type genus, Ammotrecha Banks, 1900, into the broad arena of solifuge systematics.…”

The solifuge genera Eutrecha Maury, 1982 and Xenotrecha Maury, 1982 are among the rarest and most elusive groups of camel spiders in the New World. Since their inception, both genera have remained unclassified within the subfamilial scheme of Ammotrechidae, where they belong, and their systematic position and affinities to other genera continue to be unexplored. This contribution addresses the affinities that Eutrecha and Xenotrecha have to the type genus of Ammotrechinae, Ammotrecha Banks, 1900. Based on the taxonomic distribution of characters shared by these genera, it is proposed that the three are closely related and classified into Ammotrechinae. Revised diagnoses are presented for Ammotrechinae s.str., Eutrecha, and Xenotrecha, and redescriptions are presented for species of these genera, when possible. A new species, Eutrecha belenensissp. nov., is described from Colombia, raising to three the number of species in the genus. New material of Eutrecha florezi Villareal-Blanco, Armas and Martínez, 2017 and Xenotrecha huebneri (Kraepelin, 1899) is referenced, thus extending the distribution range of these species in Colombia and Brazil, respectively. Ammotrechinae s.str. is here defined by the presence of a retroventral longitudinal carina on the movable finger of the chelicerae and a cleavage plane basally on the femur of pedipalps, among other characters. The cleavage plane allows the pedipalp to be autotomized, representing the first report of pedipalp autotomy in Solifugae. This work also presents a discussion on the taxonomy of Ammotrechidae and delves into some aspects that affect the current delimitation of some of its subfamilies.

The smallest area shaped a big problem: a revision of the placement of the Ventania sky island in the biogeography of South America

The placement of the southern border of the Neotropical region, called the Subtropical Line, is a long-lasting point of discussion. Its most debatable section runs around the Pampean province, where an isolated mountain system called Ventania has Andean connections surrounded by Neotropical biota. To answer where to place the Subtropical Line, a thorough revision of the biogeography of Ventania is needed. Thus, we characterized Ventania as an area of endemism and conducted a similitude analysis to compare it with surrounding systems using stenoic taxa. Then we compiled the disjunct distributions in Ventania and the phylogenetic information of its endemic taxa to know with which other areas it is related. We also compared the biogeographic differences with Tandilia, the nearest mountain system. We found that Ventania is a small but well-defined area of endemism mostly related to the Andean and South American Transition Zone (SATZ) provinces. Relatedness with the Pampean province is less than had been thought. We suggest that Ventania is a SATZ sky island province, and the smallest continental province of the world. The Subtropical Line should therefore be placed in the southern border of the Pampean province, with Ventania as a SATZ island inside the Neotropical region.

Changes in Male Behavior in Response to Female Chemical Stimulus in an Understudied Arthropod Model

Intraspecific sexual communication, crucial in reproductive interactions, often involves the interchange of signals like vibrations, visual signals, and chemical compounds like sex chemical cues. Within the arachnids, solifuges (“camel spiders”) are an understudied group in terms of the detection of chemical compounds during mate searching and sexual interactions. In solifugids, the malleoli, chemoreceptor structures located on the ventral side of legs IV, are putative structures capable of capturing chemical signals. Our study focused on chemical male perception of female cues in Titanopuga salinarum (Ammotrechidae), examining associated behavioral modifications and the role of malleoli. We analyzed alterations in the motion pattern (activity pulse) and specific behaviors performed by males in association with female chemical stimuli. Using experimental arenas, we exposed males to female chemical cues stimuli similar to those available at the field. Stimuli comprised females (F) and cuticular extracts (CE), with corresponding controls. Males with intact malleoli (N = 26 with F, N = 20 with CE) were compared to those with malleoli removed (N = 21 with F, N = 17 with CE). We found partial evidence that males detect chemical cues of females deposited on the substrate. We observed no differences in the duration and number of the activity pulses spent in the zones with and without stimuli in any of the groups analyzed. However, the males exhibit significant changes in locomotion patterns in response to female chemical cues, suggesting a behavioral response to these stimuli. This finding suggests that the males of this species detect the female chemical cues and modify their behavior, and can quickly gather the necessary olfactory information where the stimulus is located. In addition, we found a possible condition‐dependent regime for the detection of female cues by males, which would be expected from life‐history characteristics of T. salinarum. Our findings prompt discussion from a sexual selection perspective, suggesting the importance of chemical communication in intraspecific interactions in this elusive but fascinating animal model.
