“…In addition, the specimens used by Brtek to complete the original description of P. stygia came from Slovakia and not from the type locality of the species; thus, they could correspond to a different species. Due to this taxonomic uncertainty, Dancau and Serban (1963) decided to describe a new species, P. motasi (detailed redescription by Serban 1972). The descriptions of the latter two species are very thorough and are used here to establish comparisons.…”

Three new species of Parabathynellidae (Crustacea: Bathynellacea) are described using morphological and molecular data, and additional populations identified as Texanobathynella cf. bowmani are placed within a molecular phylogeny for the group. The finding of Montanabathynella pecosensis sp. nov. entails a southern range expansion of over 1500 km for the genus, previously thought to be restricted to Montana, USA. Montanabathynella pecosensis sp. nov. displays a unique combination of morphological features, including eight main teeth on the labrum; four and six teeth on the pars incisiva and pars molaris of the mandible, respectively; eight teeth on the distal endite of MxI; epipod present on ThII and III; four teeth on the first segment of female ThVIII; and an unpronounced anal operculum. The other two new species described here belong to the genus Texanobathynella Delamare Deboutteville et al., 1975, previously consisting of only two species. Both species, Texanobathynella aaronswinki sp. nov and T. coloradoensis sp. nov., display combinations of morphological features distinct from the other two previously known species of the genus. Mitochondrial (COI) and nuclear (18S) markers support the validity of the new species and enable us to place them, along with T. cf. bowmani, within a larger phylogenetic framework of the Parabathynellidae.

“…So, we can clarify here that the epipods, given their well-known branchial function in other malacostracans (see Grindley and Hessler, 1971;Burnett and Hessler, 1972), should always remain unarmed. However, the converse is true in primitive parabathynellids such as Parabathynella stygia Chappuis, 1926, andParabathynella motasi Dancau andSerban, 1963, in which the female Th VIII is armed with two and three setae, respectively.…”

Indobathynella prehensilis n. gen., n. sp., an Aberrant Species of Bathynellacea (Eumalacostraca) from India

A B S T R A C TA new bathynellacean, Indobathynella prehensilis n. gen., n. sp., is described from farm bores in southeastern India. This is an aberrant species, possessing such a unique combination of plesiomorphic and apomorphic characters that it cannot be assigned outright to any of the three known families of the order Bathynellacea, viz., Bathynellidae, Parabathynellidae, and Leptobathynellidae. And yet, it is provisionally placed in Bathynellidae pending reconstruction of the phylogenetic relationships within Bathynellacea. This decision is based mainly on the following plesiomorphies: 1) antennule is 7-segmented; 2) antenna has exopodal segment; 3) mandibular palp is 3-segmented; and 4) male thoracopod VIII has a basal penile lobe. The new taxon also displays some close apomorphic affinities with Parabathynellidae such as a 3-segmented prehensile maxilla, a lobe-like female thoracopod VIII, and a 1-segmented pleopod I. The other spectacular apomorphies of the new species, some of them suggesting its possible neotenic origin, are unique to Bathynellacea as a whole, and these include: 1) antenna is 4-segmented, with extremely reduced armature; 2) gnathobase consisting of 5 distinct teeth is fused with the first segment of mandibular palp; 3) thoracopods I-VII have 2-segmented exo-and endopod, except for 3-segmented endopod on thoracopod I, and with only a single endopodal seta on thoracopods II-VII; and 4) male thoracopod VIII is greatly reduced and uncinate, with exopod being fused with basis and having only two setae. All in all, the new taxon seems to be a crucial phylogenetic link between Bathynellidae and Parabathynellidae. A note on the ecology and biogeography of the new species is also added.

Montanabathynella salish gen. nov. sp. nov., of the family Parabathynellidae, from Montana, USA, is described. The new species displays several exclusive characters: distal endite of the maxillule with nine claws and a very large and distinctive male thoracopod 8 with four lobes in the basal penial region and a long recurved exopod without setation. It also presents a unique combination of characters: antennule seven-segmented; antenna six-segmented; labrum with 18 teeth; exopod of thoracopods three-to six-segmented, endopod with one dorsal seta on the first and second segments and epipod only present on thoracopods 4 to 7; pleopods absent; endopod of thoracopod 8 male with two setae and exopod without setae; female thoracopod 8 having two segments, first segment with two groups of denticles and the second one with three long barbed setae; 15 spines on sympod, four spines and spinous process on endopod and 12 setae on exopod of uropod.
