Background: The description of Platymeris biguttatus
(Linnaeus 1767) nymphal instars as well as the prediction of the
potentially suitable ecological niche was the main goal of this study.
Our research was based on 258 specimens of P. biguttatus
species of museum collections. A set of 23 environmental predictor
variables covering Africa was used at ecological niche modeling - a
method performed using the Maxent software to prepare potential
distribution maps for this species.
Results: The results suggested the most suitable areas seen as potentially suitable ecological niche for P. biguttatus
in Africa. A jackknife test showed that temperature seasonality and
percentage of tree cover were among the most important environmental
variables affecting the distribution of the species. The analysis of
climate preferences shows that most of the potentially suitable niches
for this species were located in the area of tropical savanna climate,
with a small participation of tree vegetation.
Conclusions: P. biguttatus
was only known to be widely distributed in the tropical part of
continental Africa. Thanks to the ecological niche modeling methods and
the museum data on the occurrence of the species, we introduced new
information about potentially suitable ecological niches and the
possible range of distribution.
Key words: Africa; Comparison of niches; Ecological niche modeling; Habitat suitability; Species distribution.
