“…Knowledge of the geographical distribution of obligatory subterranean fauna in Brazil is fragmented compared to Europe and Asia, where a higher level of knowledge has been achieved ( Botosaneanu 1986 , Juberthie and Decu 2001 , Deharveng et al 2009 , Stoch et al 2009 , Brancelj et al 2013 ). The first list of obligatory subterranean fauna of Brazil was published in the 1980s and comprised five areas ( Dessen et al 1980 ).…”

The subterranean environment harbors species that are not capable of establishing populations in the epigean environment, i.e., the obligatory subterranean species. These organisms live in a unique selective regime in permanent darkness and usually low food availability, high air humidity in terrestrial habitats, and low temperature range allied to other unique conditions related to lithologies and past climatic influences. The pressure to increase Brazil’s economic growth relies on agricultural/pastoral industries and exporting of raw materials such as iron, limestone, ethanol, soybean, cotton, and meat, as well as huge reservoir constructions to generate electricity. Mining (even on a small scale), agricultural expansion, and hydroelectric projects are extremely harmful to subterranean biodiversity, via the modification and even destruction of hypogean habitats. The Brazilian subterranean species were analyzed with respect to their distributions, presence on the IUCN Red List, and current and potential threats to hypogean habitats. A map and three lists are presented, one with the described obligatory subterranean species, one with undescribed taxa, and one with the current and potential threats to the hypogean environment. To date, 150 obligatory subterranean species have been recorded in Brazil, plus at least 156 undescribed troglomorphic taxa, totaling 306 Brazilian troglobites/obligatory cave fauna. We also analyzed the current and potential cave threats and the conservation actions that are underway to attempt to compensate for loss of these habitats. In according to the Brazilian legislation (Decree 6640) only caves of maximum relevance are fully protected. One strategy to protect the subterranean fauna of Brazil is the inclusion of these species in the IUCN Red List (one of attributes that determines maximum relevance for caves); however, one of the IUCN assumptions is that the taxa must be formally described. It is clear that the description and proposed protection of Brazilian subterranean biodiversity depends on more systematics studies.

“…The origin of the stygofauna of Pha-Ngan Island might as a consequence be related to vicariance and dispersal events, and is complicated by the complex geological history of the island, and by the paucity of information on the harpacticoid biocoenosis from freshwater habitats of the adjacent mainland. In fact, most of the investigations on groundwater-dwelling fauna of Southeast Asia have been conducted in caves (see Brancelj et al 2013 for a review); the only other Parastenocarididae recorded so far are Asiacaris dispar Cottarelli et al (2010) from the interstitial hyporheic habitat of Pha-Ngan Island (see below), Parastenocaris arganoi Cottarelli and Mura, 1982 from a cave in Malaysia, Parastenocaris distincta Berera, 2006 andHorstkurticaris mangyans (Bruno &Cottarelli, 1999) from the interstitial hyporheic habitat in the Philippines. All of these taxa are phylogenetically distant from Kinnecaris.…”

Three new species of hyporheic Parastenocarididae from Turkey and Thailand are described in this paper, based on their morphological features. Kinnecaris xanthi sp. nov. and Kinnecaris draconis sp. nov. were collected in Anatolic Turkey, respectively from one and two rivers; Kinnecaris iulianae sp. nov. was collected from several streams on Pha-Ngan Island (Thailand). The two new species from Turkey both lack the typical pitted integument and their P5 fused with the intercoxal sclerite in both sexes; they share a similar shape of the caudal rami in both sexes and of P4 in male. They differ in the ornamentation of the genital double-somite and the armature of A1 in females; in the ornamentation of the anal operculum; in the shape of P2 endopod of both sexes, and P3 endopod of females; in the ornamentation of the first exopodal segment of P3 in males, and in the armature of P4 endopod in females. Kinnecaris iulianae sp. nov. shares with the other species from the Oriental and Australian Region the presence of a pitted cuticle, the size and shape of caudal rami and the shape and ornamentation of P3 in the males, and is characterized by the ventral ornamentation of the genital double-somite and urosomites of the females, and by the lack of ornamentation at the insertion of the P4 endopod of both sexes. The descriptions of these three new Kinnecaris widen the distribution of the genus which, so far, was considered Gondwanian. In this paper, we also re-examine the diagnostic characters of the genus and their presence and/or variability in the known species of Kinnecaris, discuss the taxonomic position of Kinnecaris lyncaea and emend the genus diagnosis.

“…In Southeast Asia, approximately 42 species of groundwater copepods belong to the genera Asiacaris Cottarelli, Bruno et Berera, 2010, Attheyella Brady, 1880, Boholina Fosshagen et Iliffe, 1989, Bryocyclops Kiefer, 1927, Elaphoidella Chappuis, 1929, Epactophanes Mrázek, 1893, Fierscyclops Karanovic, 2004, Hadodiaptomus Brancelj, 2005, Kinnecaris Jakobi, 1972, Nitokra Boeck, 1865, Onychocamptus Daday, 1903, Parastenocaris Kessler, 1913, and Phyllognathopus Mrázek, 1893. Most of the species are recorded from Thailand, and have been collected from epikarstic habitats (Brancelj et al, 2010(Brancelj et al, , 2013Watiroyram et al, 2012;Watiroyram et al, 2015aWatiroyram et al, , b, 2017Watiroyram, Brancelj, 2016;Karanovic et al, 2017, Как Boonyanusith et al, 2018;Watiroyram, 2018a, b). However, no representative of the genus Parapseudoleptomesochra has been reported from Thailand.…”

A new species of freshwater harpacticoid copepod, Parapseudoleptomesochra phayaoensis sp.n., was found in a sample collected from a cave in northern Thailand. The new species resembles P. italica Pesce et Petkovski, 1980; however, it differs from P. italica by (1) the armature of baseoendopod and exopod of the fifth leg in both sexes, (2) the setal formula on P1 Exp-3 and P3-P4 Enp-3 and (3) by having a long inner accessory seta (seta VI) on the caudal rami in the female. To our knowledge, this is the first species of the genus
