M. Baehr, LELEUPIDIINI FROM THE ORIENTAL REGION - 2 - THE GENUS GUNVORITA LANDIN (INSECTA, COLEOPTERA, CARABIDAE, ZUPHIINAE), Revue Suisse de Zoologie, 105(2), 1998, pp. 261-318
The genus Gunvorita Landin is revised and the following 13 new species
from Nepal and northeastern India are described and illustrated: Gunv
orita angusticeps, G. besucheti, G. depressipennis, G. hamifera, G. in
ermis, G. laeviceps, G. minor, G. nepalensis, G. ovaliceps, G punctipe
nnis, G. schawalleri, G. smetanai, and G. uncinata. The male genitalia
of G. indica Darlington are described and figured. A key to all 16 kn
own species is provided. Scenario's of the possible evolution and biog
eographic history of the Oriental-Australian Leleupidiini are presente
d, even though the phylogenetic relations of and within the three gene
ra occurring in the Oriental region are not yet settled. Striking gaps
in distribution of Leleupidiini in the Oriental region and some phylo
genetic evidence indicate at least two, or even more probably, three i
ndependent colonization events of Leleupidiini in southern Asia: namel
y the genus Paraleleupidia to southern India, the ancestral stock of C
olasidia to Malaysia, and the ancestral stock of Gunvorita to the pre-
Himalayan area of Nepal to northeastern India. But another scenario is
also conceivable with colonization of the ancestral stock of Colasidi
a and Gunvorita to Malaysia and with later spreading of Colasidia to t
he southeast and Gunvorita to the northwest. The immigration is believ
ed to have occurred by drifting on the Indian plate (Paraleleupidia) a
nd on terranes of the so-called ''Sundaland'' (Colasidia and Gunvorita
). Consequently, the Oriental-Australian Leleupidiini are derived from
ancestors that were formerly distributed in the part of Gondwanaland
situated east to Africa. Therefore, Leleupidiini most probably are of
pre-Cretacious age, and they are a further example of rather recent im
migration of an old Gondwanan element into the Australian region from
the north.
