Summary 1. Growing recognition of the ecological significance and biodiversity of groundwater fauna in Australia has led to statutory requirements for monitoring these communities prior to resource development. However, the efficiency of methods for assessing community composition and taxa richness remains untested, hampering the collection of reliable data for compliance. 2. We assessed the efficiency of two commonly‐used methods to sample groundwater fauna (net hauls and pumping) in bores in two contrasting regions (Dubbo and upper Hunter Valley) of eastern Australia. Repeated sets of seasonal samples from the upper Hunter Valley bores were used to test whether once‐off sampling was sufficient for compliance purposes. 3. All taxa collected by the net method were also captured in pump samples. In addition, pumping yielded more taxa, higher total abundances, and higher numbers of the two most common taxa (syncarids and copepods) than the net. Ten net hauls in the upper Hunter Valley bores collected, on average, 64% of the taxa and 44% of total abundance. When combined with the first 100 L from pumping, cumulative totals rose to 92.5% and 74.5% respectively. Similar trends occurred in bores near Dubbo, indicating that net hauls alone under‐sampled groundwater faunal communities. Multivariate analyses revealed substantial differences in community composition as each incremental subsample was added. 4. Temporal changes in community composition in the Hunter Valley aquifer were marked yet inconsistent across the bores. Initial once‐off sampling collected 30–87% of the total taxa from each bore and new taxa were still being collected after four sampling periods in over half the bores. This shows that more than one sampling occasion is needed for comprehensive assessments of groundwater biodiversity. 5. Successful compliance monitoring of groundwater fauna requires cost‐effective sampling that will not overlook potentially vulnerable taxa or miss ecologically relevant changes in community composition. Currently, a lack of suitable bores seems to be the main constraint on accurate assessment of groundwater invertebrate community composition in these two areas of eastern Australia.

“…The different environmental conditions in groundwater favor radiation which leads to the formation of the cryptic species [3]. The 'crassicaudis' species complex was also frequently reported from groundwater in Central Spain [44], Germany [45,46], Austria [39], USA [47][48][49], Japan [50], and Australia [51]. It also occurs in the groundwater of the mountain regions of Poland [6], while it was rarely recorded in the surface water bodies in Poland.…”

Our results are the first insight into groundwater copepods of the Polish Lowland. The sampling was conducted in 28 wells in north-eastern Poland, and Copepoda were present in 16 wells. We have identified six Copepoda species and one Cladocera. We have classified four species as stygophiles—Eucyclops serrulatus, Diacyclops bisetosus, Diacyclops crassicaudis, and Cyclops furcifer. These species were frequently found in studied wells of different regions of north-eastern Poland, often in high numbers, and females with egg sacs were observed. We present a detailed morphological description of these species, together with molecular characteristics based on mitochondrial DNA markers (COI gene) for E. serrulatus, D. bisetosus, and D. crassicaudis, and 12S ribosomal RNA for C. furcifer. We also present the development of abnormal structures in one specimen of D. crassicaudis, where the upper part of furcal rami was fused to form a single plate.

“…Barr & Reddell (1967) reported the occurrence of epigean species of Eucyclops and Acanthocyclops in the adjacent Carlsbad Caverns. Hence, karstic aquifers usually harbour both epigean and hypogean species (Rouch & Danielopol, 1997;Bruno et al, 2003). In the Rustler formation aquifer recharge takes place by flow from deeper aquifers and percolation of surface water (Powers et al, 2006); thus, it was expected that this mixed pattem (i.e., epigean -|-hypogean forms) would be observed in the copepod fauna of these caves.…”

A new species of the freshwater cyclopine copepod genus Diacyclops is described from a North American cave system in SE New Mexico, U.S.A. The new species, D. nikolasarburni n. sp., differs from its congeners by its having of a unique combination of characters including: 17-segmented antennules, three-segmented rami in legs 1-4, a basic 2333 spinal formula with a highly variable pattern, naked inner margin of caudal rami, but dorsal surface with spinules, subequal terminal spines of leg 4 endopod, and inner spine of fifth leg about as long as bearing segment. This species has also a variable length/width ratio of the caudal ramus (4.6-6.0, average 5.0); the lateral caudal seta is inserted on the distal one-quarter of ramus. The 2333 spinal formula was dominant (55%) in the population but other patterns were also present. The new species belongs to Group 1 species of Diacyclops (sensu Reid & Strayer, 1994). The local population of this stygobiotic species probably resulted from radiation-stranding processes of epigean forms of widely distributed Diacyclops and is probably endemic to this cave system.
