Background: The redescription of Platymeris rhadamanthus Gerstaecker, 1873 as
well as the designation of lectotype and paralectotype, plus the
prediction of the potentially suitable habitat was the main goal of
this study. Our research were based on 262 specimens of museum
collections of P. rhadamanthus
species and a set of 23 environmental predictor variables, all recorded
in a 1x1 km grid covering Africa. Ecological niche modelling was
performed using the MAXENT analyses to produce predictive potential
distribution maps for this species and its colour forms separately.
Results: The results suggested the most suitable
areas of distribution of P.
rhadamanthus, both for species as a whole and also for the
colour forms. A jackknife test showed that the precipitation of coldest
quarter and herbaceous vegetation were the most important environmental
variables affecting the distribution of P. rhadamanthus. After analyzing
the climatic preferences, this species seems to be related mainly to
the tropical savanna climate, subtropical highland variety of the
oceanic climate and humid subtropical climate. An analysis of
environmental variables also showed that this species prefers areas
with herbaceous vegetation, with a small participation of trees, which
is probably caused by food preferences of its victims.
Conclusions: P. rhadamanthus so far was only
known that it occurs in widely understood tropical Africa. On the base
of the museum data on the occurrence of the species and ecological
niche modelling methods we provided new and valuable information of the
potentially suitable habitat, the possible range of distribution of the
species and its climatic preferences.
Key words: Africa; Ecological niche
