Chaetotaxy and morphometry of the head capsule and head appendages of the genus Derallus Sharp (Coleoptera: Hydrophilidae)
(Magnolia Press, 2020-01)
The primary and secondary chaetotaxy of the head capsule and head appendages of the three larval instars of the water scavenger beetle genus Derallus Sharp are described for the first time based on two species: D. angustus ...
Description of immatures of the genus Tropisternus Solier, subgenus Pristoternus Orchymont (Coleoptera: Hydrophilidae), with emphasis on the chaetotaxy and morphometry of larval forms
(Magnolia Press, 2014-04)
The egg cases, larvae, and pupae of Tropisternus (Pristoternus) latus (Brullé, 1837), T. (P.) ovalis Castelnau, 1840, and T. (P.) laevis (Sturm, 1826) are illustrated and described for the first time. The egg cases are ...
Chaetotaxy and larval morphometry of Cercyon praetextatus (Say) and C. quisquilius (Linnaeus) (Coleoptera: Hydrophilidae: Sphaeridiinae) and their phylogenetic implications
(Senckenberg, 2016-10)
The primary and secondary chaetotaxy of the head capsule and head appendages of the three larval instars of Cercyon praetextatus (Say, 1825) and Cercyon quisquilius (Linnaeus, 1761) are described for the first time. ...
Larval chaetotaxy and morphometry of Oosternum costatum (Coleoptera: Hydrophilidae) including a discussion of larval characters with phylogenetic relevance
(Narodni Muzeum - Prirodovedecke Muzeum, 2018-11-14)
The primary and secondary chaetotaxy of the head capsule and head appendages of the first and third larval instars of Oosternum costatum (LeConte, 1855) (Coleoptera: Hydrophilidae: Sphaeridiinae, Megasternini) are described ...
Comparative analysis of diagnostic and phylogenetic chaetotaxic characters of Berosus Leach and their implications on the relationships of the tribe Berosini (Coleoptera: Hydrophilidae)
(Elsevier Gmbh, 2018-11)
Larvae of water scavenger beetles are found in all types of aquatic and semi-aquatic environments and play an important role in the structure of these communities. Despite their diversity, morphological characters that ...
Description of immatures of Berosus decolor Knisch, 1924 (Coleoptera: Hydrophilidae: Berosini), with emphasis on chaetotaxy and morphometry
(Magnolia Press, 2015-07)
The preimaginal stages of Berosus decolor Knisch, 1924 are described for the first time, including illustrations of the egg case and all larval instars. Larval morphology of this species is studied emphasizing chaetotaxic ...
Going underwater: Multiple origins and functional morphology of piercing-sucking feeding and tracheal system adaptations in water scavenger beetle larvae (Coleoptera: Hydrophiloidea)
(Oxford University Press, 2021-09)
Larvae of water scavenger beetles (Coleoptera: Hydrophiloidea) are adapted to a wide variety of aquatic habitats, butlittle is known about functional and evolutionary aspects of these adaptations. We review the functional ...
Population parameters of two water scavenger beetles: Derallus angustus Sharp and Enochrus vulgaris (Steinheil) (Coleoptera: Hydrophilidae) in permanent ponds: spatial distribution and microhabitat preference
(Centro Studio Faunistica Ecologia Tropicali, 2016-12)
The spatial distribution, temporal variation, and microhabitat preference of two populations of aquatic Coleoptera were analysed in permanent ponds located in the province of Corrientes, Argentina. Samples were collected ...
Larval chaetotaxy and morphology are highly homoplastic yet phylogenetically informative in Hydrobiusini water scavenger beetles (Coleoptera: Hydrophilidae)
(Oxford University Press, 2021-06)
Phylogenetic analyses testing the monophyly of the tribe Hydrobiusini and the relationships among its genera are performed based on a data matrix including characters of larval morphology and morphometrics, larval chaetotaxy ...
