Amblypygi (whip spiders) are terrestrial chelicerates inhabiting the subtropics and tropics. In morphological and rRNA-based phylogenetic analyses, Amblypygi cluster with Uropygi (whip scorpions) and Araneae (spiders) to form the taxon Tetrapulmonata, but there is controversy regarding the interrelationship of these three taxa. Mitochondrial genomes provide an additional large data set of phylogenetic information (sequences, gene order, RNA secondary structure), but in arachnids, mitochondrial genome data are missing for some of the major orders. In the course of an ongoing project concerning arachnid mitochondrial genomics, we present the first two complete mitochondrial genomes from Amblypygi. Both genomes were found to be typical circular duplex DNA molecules with all 37 genes usually present in bilaterian mitochondrial genomes. In both species, gene order is identical to that of Limulus polyphemus (Xiphosura), which is assumed to reflect the putative arthropod ground pattern. All tRNA gene sequences have the potential to fold into structures that are typical of metazoan mitochondrial tRNAs, except for tRNA-Ala, which lacks the D arm in both amblypygids, suggesting the loss of this feature early in amblypygid evolution. Phylogenetic analysis resulted in weak support for Uropygi being the sister group of Amblypygi.

ABSTRACT Amblypygids are among the main predators in the ferriferous caves in Carajás National Forest, state of Pará (Amazon region of Brazil). One of the most common amblypygid species in this region is Heterophrynus longicornis (Butler 1873), and its most frequent prey are crickets of the family Phalangopsidae, which are abundant in the caves of Pará. Because they are primarily predators, necrophagy by amblypygids is not frequent in nature, and there are only two literature records of necrophagy of bats by Amblypygi. On December 11th, 2013, we observed an individual H. longicornis eating a bat carcass in a Pará ferriferous cave. The amblypygid exhibited considerable interest in the bat’s carcass, and it did not interrupt its meal even when lamps or a camera’s flash were pointed in its direction. The availability of nutrients in the carcass must promote this opportunistic behavior in caves, especially considering the habitual scarcity of trophic resources in underground environments when compared to epigean environments.

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.timorensissp. 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.

While the unique sensory system and neuroanatomy of amblypygids suggest that olfaction is important in their lives, to date no behavioral data exist to support this suggestion. To gain insight into amblypygid ecology and behavior, an individual markrecapture study was conducted on the Costa Rican amblypygid Phrynus parvulus. Within two 50 by 25 m plots, the distribution and movement patterns of individual amblypygids were recorded for over 2 months. A total of 88 adult individuals (60 males and 28 females) were marked, with an average 51% resighted. Females were resighted more frequently than males (75% females, 40% males). The sexes did not differ in their frequency or movement distance, but females were more likely to be seen on the same tree over time. While both sexes potentially wander in search of mates, females may also be searching for a good crevice, or diurnal hideout. Once a female has mated and laid eggs, she likely remains stationary. Movement patterns and tree choice seem to be dictated by both the presence of conspecifics and environmental factors such as tree surface area, moss cover, and the presence of buttressing. Cumulative observational data collected over 3 years suggest that the main breeding season for this species is October-January. Both mate attraction and navigation may be facilitated by the olfactory capabilities of amblypygids, while their giant interneurons may be involved in their foraging behavior.

ABSTRACTThe Late Carboniferous whip spiderGraeophonus anglicusPocock, 1911 (Arachnida: Amblypygi), is redescribed on the basis of the holotype and nine other specimens all preserved in sideritic nodules from the British Middle Coal Measures of Coseley, Staffordshire, UK. This species is clearly basal with respect to most living whip spiders, expressing numerous plesiomorphic character states and can be referred to both the suborder Paleoamblypygi and the ‘living fossil’ family Paracharontidae (with one Recent species), the latter based on an explict character of dorsal spination on the pedipalp femur. This suggests that crown-group Amblypygi originated by at least the mid-Palaeozoic.

The subfamily Phryninae (Arachnida: Amblypygi) has not been recently revised, which causes many difficulties for species identification. Thus far, no phylogenetic hypothesis has been proposed for this subfamily. The nomenclature of diagnostic characters is not uniform, and most illustrations are poorly detailed. We reviewed the subfamily Phryninae, redescribed all known species, and described six new species. We proposed a unified nomenclature for teeth of chelicerae and pedipalpal spines. We performed a phylogenetic analysis using total evidence and direct optimization in the program POY. We built a morphological matrix of 92 terminals and 174 characters, and a molecular matrix with 1557 pb (markers COl, 12s and 16s). Both sets of information were analyzed separately to understand their influence over the total evidence analysis. The results of the three analyses were different: the morphological analysis did not recover the subfamily Phryninae as monophyletic, this analysis produced 90 equally parsimonious topologies, however, the strict concensus tree had good resolution. The molecular analysis did not recover the family Phrynidae as monophyletic, but Phryninae was recovered. Total evidence analysis allowed for obtain just one more parsimonious hypothesis which included all species of Phrynidae, and resolved the politomies obtained with the analysis using morphology only, in this hypothesis Phrynidae and its subfamilies are monophyletic. ln all results, the genera of Phryninae were polyphyletic. We selected the tree of total evidence analysis to build a new taxonomic proposal, we decided to keep Acanthophrynus, Phrynus, and Paraphrynus and to create five new genera: Caicedophrynus gen. nov., Cronopiophrynus gen. nov., Gabophrynus gen. nov., Gentiloprynus gen. nov., Girondophrynus gen. novo Accordingly, we proposed 44 nomenclatural changes. Our results showed that the diversity of this group could be greater, therefore, we highlight that populational and phylogeographic studies of Phryninae are important
A subfamília Phryninae (Arachnida: Amblypygi) não possui uma revisão recente. Isso traz muitas dificuldades na identificação das espécies. Nenhuma hipótese filogenética para a subfamília foi proposta. A nomenclatura dos caracteres diagnósticos não é uniforme e a maioria das ilustrações não é suficientemente detalhada. Aqui, nós revisamos a subfamília Phryninae, redescrevemos as espécies conhecidas e seis espécies novas, e propomos uma nomenclatura uniforme para os dentes das quelíceras e espinhos dos pedipalpos. Nós realizamos uma análise filogenética usando evidência total e otimização direta no programa POY. Construímos uma matriz morfológica de 92 terminais e 174 caracteres, e uma matriz molecular usando 1557 pb (marcadores COI, l2S e 16S). Os dois conjuntos de informação foram analisados separadamente para perceber a influência de cada um deles na análise de evidência total. Os resultados das três análises foram diferentes. A análise morfológica não recuperou a subfamília Phryninae como monofilética, resultando em 90 topologias igualmente parcimoniosas, Porém, a árvore de consenso estrito teve uma boa resolução. A análise molecular recuperou Phryninae como monofilética, embora não tenha recuperado a família Phrynidae. A análise de evidência total permitiu obter uma única hipótese mais parcimoniosa a qual inclui todas as espécies de Phrynidae, e permitiu resolver as politomias obtidas na análise morfológica. Nesta hipótese, tanto Phrynidae como suas subfamílias se mantiveram monofiléticas. Em todos os resultados, os gêneros de Phryninae são polifiléticos. A árvore da análise de evidência total foi selecionada para elaborar uma nova proposta taxonômica. Mantivemos os gêneros Acanthophrynus, Phrynus e Paraphrynus e criamos cinco gêneros novos: Caicedophrynus gen. nov., Cronopiophrynus gen. nov., Gabophrynus gen. nov., Gentilophrynus gen. nov., e Girondophrynus gen. novo Propusemos 44 mudanças nomenclaturais, Nossos resultados sugerem que a diversidade do grupo é maior do que a conhecida. Isso nos faz considerar importante análises populacionais e filogeográficas em Phryninae

A new genus and a new amblipygeal species are described here based on an almost complete specimen from the limestone of Crato Member (Aptian) of the Santana Formation, the eastern portion of the Araripe Basin in southern Ceará. It is attributed to the Charinidae (Holocene) family, although it presents four pairs of spines arranged in two rows and distally growing in the tibia of pedipalpo, which can be an ancestral feature, sharing with the referred family all other diagnostic features. Tafonomically, the specimen must have undergone a little post-mortem transport, being deposited in the probably anoxic bottom of a lake, thus allowing its preservation. The species of the specimen described should have been troglophile for possessing pulvilli on the legs, so living in rocky crevices in emerged lands near by water bodies, under warm and arid climate. The specimen described is the only known fossil representative of the Charinidae family so far known, being the oldest form of this family, which extends its temporal distribution. It can be assessed the importance and rarity of the Amblypygi specimens occurring in Crato Member, Santana Formation, that outcrops in Nova Olinda. There is little fossil occurrence of this order of arachnid in the Mesozoic, if we consider that, all over the planet and in about 300 million years, only some of these fossil specimens are known.
Um novo gênero e uma nova espécie de amblipígeo são aqui descritos com base em um exemplar quase completo proveniente dos calcários laminados do Membro Crato (Aptiano) da Formação Santana, porção leste da Bacia do Araripe no sul do Ceará. Atribuído à família Charinidae (Holoceno), apesar de apresentar quatro espinhos pares dispostos em duas fileiras e distalmente crescentes na tíbia do pedipalpo, o que pode ser uma plesiomorfica, compartilhando com a referida família todas as demais feições diagnósticas. Tafonomicamente, o exemplar deve ter sofrido curto transporte post-mortem, sendo depositado no fundo provavelmente anóxico de um lago, permitindo assim sua preservação. A espécie do exemplar descrito deveria ter sido troglófila por possuir pulvilli nas pernas, portanto vivendo em fendas rochosas em terras emersas bastante próximas a corpos aquosos, sob clima quente e árido. O espécime descrito se constitui no único representante fóssil da família Charinidae até agora conhecido, sendo a forma mais antiga desta família, o que amplia sua distribuição temporal. Pode-se avaliar a importância e raridade dos espécimes de Amblypygi ocorrentes no Membro Crato, Formação Santana, aflorante em Nova Olinda. Pouca ocorrência de fóssil desta ordem de aracnídeo no Mesozoico, se considerarmos que, em todo o planeta e em cerca de 300 milhões de anos, só alguns desses exemplares fósseis são conhecidos.

Karyotype analysis of selected species from arachnid orders Amblypygi and Uropygi Whip spiders (Amblypygi) and whip scorpions (Uropygi) represent relict arachnid orders which has been found already at Upper Carboniferous strata. Although cytogenetic data from amblypygids and uropygids might be important to reconstruct karyotype evolution of arachnids, cytogenetics of these orders is almost unknown. Presented study is aimed in analysis of karyotype and meiosis in 16 species of Amblypygi and 4 species of Uropygi. Both groups are characterized by considerable range of diploid chromosome numbers (2n = 24 - 86 in Amblypygi and 36 - 66 in Uropygi). Analysed species does not exhibit morfologically differentiated sex chromosomes. Differentiation of sex chromosomes on molecular level was revealed in amblypygid Paraphrynus mexicanus by comparative genome hybridization. Obtained data indicate XY/XX sex chromosome system in this species. Comparison of karyotype data indicates reduction of chromosome numbers during evolution of both orders. In Amblypygi, this reduction was accompanied by increase of number of biarmed chromosomes. This trend is not apparent in Uropygi. Karyotypes of most analysed amblypygids and uropygids are also characterized by low amount of heterochromatin. Most studied species exhibit two pairs...
