Dytiscidae (commonly known as "predaceous diving beetles") are the most speciose water beetle family, with over 4,400 known species. They are distributed world-wide, being more common in tropical and subtropical areas. In ...

Here we provide evidence that confinement in Robinson Crusoe Island (located about 660 km west of continental Chile) over evolutionary time leads to strong morphological modifications in diving beetle (Dytiscidae) larvae. ...

Larval morphology of the monogeneric subfamily Coptotominae (Coleoptera: Dytiscidae) is described and illustrated in detail, with particular emphasis on morphometry and chaetotaxy. Larvae of Coptotomus Say are unique within ...

The second and third instars of Laccornellus lugubris (Aubé) are described and illustrated for the first time, including detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last ...

The first instar of Hoperius planatus Fall, 1927 is described and illustrated for the first time with an emphasis on the chaetotaxy of the head capsule, head appendages, legs, last abdominal segment, and urogomphi. Hoperius ...

The phylogenetic position of Hydrovatus Motschulsky was investigated based on a cladistic analysis of 18 hydroporine taxa and 69 characters from larval morphology. For this purpose, the three larval instars of H. caraibus ...

Larval morphology of the Neotropical endemic dytiscid genus Amarodytes Régimbart is investigated. All three larval instars of A. duponti (Aubé) are described and illustrated with particular emphasis on morphometry and ...

The second and third instars of Yola wraniki Wewalka, 2004 are described and illustrated for the first time, with detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal ...

Generic keys for the identification of larvae of Dytiscidae from Argentina are presented. A total of 27 dytiscid genera are recognized in Argentina, included in 16 tribes and seven subfamilies. Twenty-two of the 27 genera ...
