Resumen:
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 planatus is characterized by the presence of additional
campaniform sensilla (pores) on the frontoclypeus, representing a unique character
state within the tribe Colymbetini (Colymbetinae). A phylogenetic analysis
based on 42 first-instar characters using the program TNT reinforces the
hypothesis of monophyletic origin of the Colymbetini and suggests a placement of
Hoperius Fall, 1927 as sister to a clade comprised of Neoscutopterus J.
Balfour-Browne, 1943, Meladema Laporte, 1835, and Bunites Spangler, 1972.
Members of this clade are uniquely characterized within the Colymbetini by the presence
of a large number of additional spiniform sensilla on the urogomphus.
