Catalogue of the world genera and subgenera
of the superfamilies Derodontoidea and Bostrichoidea (Coleoptera: Derodontiformia, Bostrichiformia).
Vidrine (1996) subsequently identified 20 groupings of Unionicola subgenera
based on sets of shared morphological and life-history characters.
Additional support for two subgenera
of Anemia (Schizaeaceae) from data for the chloroplast intergenic spacer region trnL-F and morphology.
The two subgenera
tend to have consistent differences in their gametophytes, with those of the Hippochaete being considerably larger and having more embryos than those of subgenus Equisetum (Campbell, 1928), sometimes reaching 3.
Costa (2011) conceded that the morphological characters had not been fully examined in all species of the subgenus Laimosemion and recognized the monophyly of the set of species included in the subgenera
Laimosemion and Owiyeye revealed by previous published molecular phylogenies.
Another unfortunate tendency is "over-splitting" of taxa, for instance in the Microveliinae, where every specially adapted clade has been described as a new genus, and many clades of Microvelia as new subgenera
, but without any knowledge about the underlying phylogenetic relationships.
This study focuses on cytogenetics of bothriurid scorpions of the genus Brachistosternus, comparing representatives of the subgenera
New classification for the composite genus Aedes (Diptera: Culicidae: Aedini), elevation of subgenus Ochlerotatus to generic rank, reclassification of other subgenera
, notes on certain subgenera
1) Their analysis found that the genus contained two subgenera
, namely Echinacea subgenus Echinacea (containing a single species E.
The number of premental lobes, three on larvae of Guignotites and two on the subgenus Hydaticus, has been presented as a diagnostic character for separation of second and third instars of the two subgenera
of Penaeus (Motoh & Buri 1984, Leelapiyanart 1989) were raised to generic level, namely Marsupenaeus, Melicertus, Penaeus, anal Fenneropenaeus (Perez Farfante & Kensley 1997).
Based on the present morphological phylogeny and previous molecular analyses, seven subgenera
are recognized: Rivulus, Cynodonichthys, Anablepsoides, Benirivulus n.
