Claw Shape

Claws may be the most common biological attachment devices in animals but relatively few studies have examined the ecological and evolutionary significance of their morphology. We performed the first geometric morphometric investigation of arthropod claws using 15 intertidal oribatid mite species from two different families living in three different habitat types to determine if claw shape is correlated with ecology. Our results show that species living on rocky shores show remarkably high and strongly curved claws while species from mangrove habitats show significantly lower and less curved claws. Euryoecious species are able to dwell in a wide range of habitats and show an intermediate claw type. These results indicate a strong relationship between claw shape and microhabitat and the best predictors of microhabitat use seem to be claw height and curvature. Claw length varied to some degree among the species but without any noticeable ecological pattern. A comparison with terrestrial and freshwater aquatic oribatid mite species, on the other hand, confirms that their claws are only half as long as that of intertidal mites and it is suggested that tidal flooding and wave action strongly selects for long claws. In this microarthropod group which occupies a vast array of microhabitats, claw morphology may play an important role in niche separation and hence demonstrate the importance of ecomorphological studies.

Four new oribatid mite species of the superfamily Galumnoidea, Pergalumna paradecoratissima sp. nov., Pergalumnaparalongisetosa sp. nov., Pergalumna ecuadorensis sp. nov. and Galumnopsis lanceosensilla sp. nov., are described fromEcuador. The genus Galumnopsis is recorded for the first time for the Ecuador. Pergalumna paradecoratissima sp. nov.is very similar in having the combination of foveolate prodorsum, striate notogaster, setiform sensilli, interlamellar setaeshorter than lamellar and rostral setae, absence of anterior notogastral margin and three pairs of notogastral porose areas,to Pergalumna decoratissima Pérez-Íñigo & Baggio, 1986 from Brazil, however it differs from the latter by morphologyof rostrum, body size, surface of anal plates and length of epimeral setae. Pergalumna paralongisetosa sp. nov. is verysimilar in having the combination of setiform sensilli, long prodorsal setae, absence of anterior notogastral margin, threepairs of notogastral porose areas and long adanal setae ad 1 and ad 2 to Pergalumna longisetosa Balogh, 1960 from CentralAfrica, however it differs from the latter by body size, lengths of sensilli and interlamellar setae, absence of medial pore,length of epimeral setae. Pergalumna ecuadorensis sp. nov. can be distinguished from all similar species by having theround rostrum, setiform sensilli, long and setiform prodorsal setae, absence of anterior notogastral margin, smooth bodysurface and three pairs of oval notogastral porose areas, and by the very long interlamellar setae. Galumnopsis lanceosen-silla sp. nov. can be distinguished from all similar species (with smooth body surface) by the morphology of sensilli which are lanceolate, with tooth in distal part.

Two new oribatid mite species viz. Papillacarus (Vepracarus) acaciensis sp. nov. and Licneremaeus indicus sp. nov. belonging to the respective oribatid families, Lohmanniidae and Licneremaeidae are described and illustrated. Specimens of both species were collected from litter of Acacia auriculiformis Benth. (Leguminosae) growing in different localities of the Calicut University Campus, Malappuram Dt. of Kerala. The family Licneremaeidae is recorded for the first time from India. Identification keys to all known species of the nominative subgenus Vepracarus and the genus Licneremaeus are also provided.

A new oribatid mite species of the genus Pilobates (Oribatida, Haplozetidae) is described from Madagascar, based on material collected from litter in Andasibe-Mantadia National Park, eastern Madagascar. Pilobates longiprocessus sp. n. differs from Pilobates africanus Ermilov and Starý, 2020 in the presence of simple notogastral setae and leg trochanters IV with triangular process distodorsally. An identification key to known species of Pilobates is provided.

Oribatid Mite Species

In the literature there is much confusion about the identity and taxonomic position of two common oribatid mite species in the family Ceratozetidae: Oribates setosus C.L. Koch, 1839, and Murcia trimaculata C.L. Koch, 1835. Related to these problems, there are contrary opinions about the validity of two ceratozetid genera, Murcia Koch, 1835 and Trichoribates Berlese, 1910, and the identity of their type species. Important conclusions on these issues have been proposed in the past (Jacot 1929; Pérez-Iñigo 1993) but these were not followed in an important recent catalog (Subías 2004). In the following, we summarize and comment on the history of these problems, and argue in the context of the current ICZN rules to preserve nomenclatural stability.
