Abstract
Here a new subgenus of Lepidocyrtus Bourlet from South America is proposed. Fractocyrtus
subgen.n. differs from other subgenera by tergal polychaetosis, dental tubercle truncate and dentes with numerous spine-like chaetae. Four new species of Lepidocyrtus are described, two of Setogaster Salmon and two of Fractocyrtus
subgen.n.
Lepidocyrtus (S.) amazonicus
sp.n. and L. (S.) multisensillatus
sp.n. are similar to L. nigrosetosus Folsom by basomedian field with chaetae smooth and dental tubercle rounded, but differ in dorsal chaetotaxy. Lepidocyrtus (F.) americanus
sp.n. and L. (F.) mateosi
sp.n. are similar by presence of numerous dental spines, but differ in chaetotaxy. Due to inconsistencies concerning scales on appendages of Lepidocyrtus subgenera, four synonyms are proposed, and the characteristics diagnostic to subgenera are shape and presence of dental tubercle, dental spines, mucronal spinelet and apical bulb of fourth antennal segment. An identification key to subgenera is also provided.
期刊介绍：
Insect Systematics & Evolution (ISE) publishes original papers on all aspects of systematic entomology and the evolutionary history of both extant and extinct insects and related groups. Priority is given to taxonomic revisions and phylogenetic studies employing morphological and molecular data. ISE also welcomes reviews and syntheses that can appeal to a wide community of systematic entomologists. Single species descriptions, regional checklists, and phylogenetic studies based on few taxa or single molecular markers will generally not be accepted.
