Anthicidae (Insecta: Coleoptera) of the Indo-Australian transitional zone
Dmitry Telnov
(The Entomological Society of Latvia, c/o Faculty of Biology, Riga, Latvia)
Anthicidae from the Indo-Australian transition zone (Wallacea, New Guinea,
Solomon Islands) were revised. The study area is among the world richest
regions for Anthicidae with 19 genera, 270 species and subspecies of recorded
on <1% of the world's
dry land area. The most diverse genera are Macratria Newman - 120 species,
Sapintus Casey - 36, and Tomoderus LaFerte-Senectere - 24 species. Species
diversity correlates
with the area of the studied islands. The largest islands, New Guinea
and Sulawesi, have
179 and 65 species respectively. From smaller islands only 1-5 species
were recorded.
Genera peculiar to the Oriental and / or Australian realms, as well as
cosmopolitan
genera, were recorded. The genera Papuanthicus and Pseudoleptaleus are
believed endemic
to the study area. The percentage of regional endemic species reaches 88%.
The
proportion of endemic species is from 85% on large islands to nearly
100% on smaller
and more isolated islands. None of the genera of Australian origin cross
Wallace's Line
to the west. Taxa of supposedly Oriental origin do not cross Lydekker's
Line to the
East. Lowland and lower montane areas are characterized by higher
Anthicidae species
diversity but a lower proportion of endemic species. Upper montane areas
(2,900 m up)
are characterized by low species diversity but up to 100% species endemism
(Patterson
theory of dependence of species richness and endemism on the altitude).
The above mentioned confirms the generally accepted view that the
Indo-Australian
transition zone is the region with highest animal species diversity
in the world and a
very important biodiversity and speciation hotspot.
