Remarks.
Bates (1889)
originally described
Trigonopeltastes nigrinus
as a variety of
Trigonopeltastes geometricus
, and
Howden (1968)
later gave
Trigonopeltastes nigrinus
full species status.
Howden (1968)
and
Howden and Joly (1998)
gave diagnostic characters for each species involving the size, indentation of pronotal triangle, elytral coloration, and pygidial markings but commented that these were based on the examination of "very few specimens" and that further study was needed. In examining longer series of
Trigonopeltastes geometricus
, I have observed that the diagnostic characters used by
Howden (1968)
to separate
Trigonopeltastes geometricus
and
Trigonopeltastes nigrinus
break down with a number of individuals exhibiting a blend of the supposed diagnostic characters used.
Bates (1889)
originally described
Trigonopeltastes carus
as a distinct species, which
Howden (1968)
synonymized with
Trigonopeltastes nigrinus
. Specimens that fall under any of the three preceding names all share the diagnostic characters used in the key and have significant lateral portions of the pygidium covered with yellow, cretaceous markings. Since I could find no justification for maintaining
Trigonopeltastes nigrinus
as a separate species, I am here synonymizing this name and
Trigonopeltastes carus
under
Trigonopeltastes geometricus
. Further study involving molecular data is desirable to test the hypothesis that
Trigonopeltastes geometricus
is a single, variable species that is distributed from Mexico to Bolivia.
Distribution.
Trigonopeltastes geometricus
and its synonyms were previously recorded from Mexico, Belize, Guatemala, El Salvador, Nicaragua, Costa Rica, Panama, Venezuela, Colombia, Ecuador, and Bolivia (
Howden 1968
,
Cave 1983
,
Maes et al. 1997
,
Howden and Joly 1998
). The specimens detailed below represent a new country record for Honduras.
