“…Berdasarkan beberapa penelitian sebelumnya, ordo Aranea memang menjadi salah satu penyumbang keanekaragaman tertinggi di ekosistem gua (Kurniawan et al, 2018b;Kurniawan et al, 2018c). Kelompok ini tergolong adaptif di ekosistem gua dan cukup banyak spesies troglobit yang hanya dapat hidup di dalam gua (cave obligate species) merupakan anggota dari ordo ini (Bertani et al, 2013;Candia-Ramírez & Valdez-Mondragón, 2014;Miller & Rahmadi, 2012).…”

AbstrakAraknida merupakan kelompok fauna yang umum dijumpai di gua dan berperan penting menjaga keseimbangan ekosistem gua. Kelompok fauna ini dapat ditemukan di seluruh zona gua baik terang, remang, maupun gelap. Penelitian ini bertujuan untuk mengetahui perbedaan keanekaragaman dan kelimpahan araknida berdasarkan zonasi gua. Pengambilan data dilakukan di 3 gua yang terletak di kawasan Karst Tasikmalaya, yaitu Gua Sarongge, Liang Boeh, dan Liang Seungit. Pencuplikan araknida dilakukan dengan teknik hand collecting, sedangkan penghitungan individu dengan direct counting. Selain itu, dilakukan pengukuran parameter abiotik yang terdiri dari suhu udara, suhu tanah, kelembapan udara, kelembapan tanah, dan intensitas cahaya. Data dianalisis dengan uji indeks similaritas Jaccard, one-way ANOVA, Kruskal Wallis, dan Canonical correlation analysis. Terdapat 311 individu araknida tergolong dalam 3 ordo dan 7 morfospesies yang berhasil dikoleksi. Mayoritas araknida tergolong kategori adaptasi troglofil. Terdapat kemiripan komposisi spesies yang tinggi antara zona remang dan gelap (indeks similaritas 0,833) dibandingkan kemiripan keduanya dengan zona terang (0,571 dan 0,429). Kelimpahan individu araknida antar zona tidak berbeda secara signifikan. Mayoritas spesies memiliki preferensi habitat dengan kondisi intensitas cahaya rendah dan kelembapan tinggi.AbstractArachnid is one of the cave-adapted fauna with diverse cave representatives and plays a vital role in maintaining ecosystem balance. This group is widely distributed in all cave zonation, namely entrance, twilight, and dark zones. This study aimed to reveal the difference in diversity and abundance of arachnids in different caves zonation. The study was carried out in three caves situated in Tasikmalaya karst region, namely Sarongge, Liang Boeh, and Seungit. Arachnids were sampled through hand collecting, while abundance was estimated through direct counting. Air and soil temperatures, relative humidity, soil moisture, and light intensity were also measured. Data were analysed through Jaccard’s similarity index, one-way ANOVA, Kruskal Wallis, and CCA. In total, 311 individuals belonged to 3 orders and 7 morphospecies were identified. Most observed morphospecies were categorized as troglophiles. There was a great degree of similarity in species composition between twilight and dark zones (similarity 0.833) compared to entrance zone (0.571 and 0.429, respectively). Meanwhile, abundance was relatively similar. Most species prefer habitats with low light intensity but high humidity.

World experts of different disciplines, from molecular biology to macroecology, recognize the value of cave ecosystems as ideal ecological and evolutionary laboratories. Among other subterranean taxa, spiders stand out as intriguing model organisms for their ecological role of top predators, their unique adaptations to the hypogean medium and their sensitivity to anthropogenic disturbance. As the description of the first eyeless spider (Stalita taenaria), an array of papers on subterranean spider biology, ecology and evolution has been published, but a comprehensive review on these topics is still lacking. We provide a general overview of the spider families recorded in hypogean habitats worldwide, we review the different adaptations of hypogean spiders to subterranean life, and we summarize the information gathered so far about their origin, population structure, ecology and conservation status. Finally, we point out the limits of the knowledge we currently have regarding hypogean spiders, aiming to stimulate future research. BackgroundReceiving poor energy inputs and being light-deficient, caves are generally considered extreme environments, characterized by low abundance and diversity of organisms. Because of their extraordinary adaptations, cave-dwelling animals offer unique study opportunities for pushing forward our current understanding of evolutionary and ecological processes [1,2]. Among other subterranean taxa, spiders are distinctive for their ecological role of top predators [3][4][5], and for the variety of functional adaptations [6], therefore representing undervalued models for the understanding the evolution of life in extreme habitats. Accordingly, subterranean spiders have served as models for physiological [7][8][9], ecological [4,5,[10][11][12], ethological [13,14] and biogeographic studies [15][16][17], among others.However, compared with other animal groups, the potential of spiders as model organisms is still under-expressed. It is possible that the paucity of studies is related to the difficulty of working in subterranean habitats and to the rarity of most subterranean species, which pose major impediments to data collection and analysis. In addition, the general lack of a state of the art on subterranean spider biology, ecology and evolution conceivably hinders advances in knowledge. In this review, we present a collection of information about spiders colonizing subterranean habitats-especially caves-and discuss their relevance in the understanding of cave life evolution and the ecology of subterranean animal communities. (a) Terminology and acronymsWe use the term troglobiomorphism to distinguish the suite of adaptations, especially morphological, to subterranean life [18]. Despite the fact that ecological categorizations often oversimplify real cases and boundaries between categories can be vague, for the sake of this review, we use the traditional speleobiological nomenclature [19] to indicate ecological distributions of species:(1) a troglobiont is strongly bound to hypogean habitats...

A new species of the spider genus Ochyrocera Simon, 1891 is described from southern Mexico. Males and females of Ochyrocera marialuisae sp. nov. were collected from a cave in Oaxaca, Mexico. With the description of the new species herein, the species diversity of the genus from Mexico increases to eight species. In addition, biogeographical comments about the distribution of the species, an updated taxonomic identification key, and a distribution map for the Mexican species are provided.
