Abstract: |
|
| |
|
The
opilionid fauna of Dobrudzha is not well studied, and Northern and
Southern Dobrudzha have not been studied equally. For example, only 15
species have been reported from Northern Dobrudzha, while from Southern
Dobrudzha they are three times less. As a result of this study and the
summarized data from literature, 17 harvestmen species (about 285 of the
Bulgarian harvestmen fauna) were found in the area of Southern
Dobrudzha. Twelve of them (Nemastoma bidentatum sparsum,
Carinostoma elegans, Mitostoma gracile, Trogulus tricarinatus, T.
closanicus, Dicranolasma giljarovi, Phalangium opilio, Zachaeus cf.
anatolicus, Egaenus convexus, Lacinus horridus, Odiellus lendli,
Astrobunus laevipes) are new for the Southern Dobrudzha. From the
territory of its adjacent regions 18 opilionid species were recorded,
four of them (Trogulus closanicus, Dicranolasma thracium, Rilaena
buresi, Eudasylobus beschkovi) being new to these regions. Notes on
expected species, endemism and conservation status of the recorded
harvestmen species are given. The similarity of the harvestmen faunas of
Northern and Southern Dobrudzha, its adjacent regions, and the Sofia
Kettle is illustrated by a dendrogram of faunistic data from the
investigated regions. |

Resumen: |
|
| |
|
La fauna de opiliones de
Bobrudzha está escasamente conocida. Lo mismo ocurre con las zonas
septentrionales y meridionales adyacentes. Por ejemplo, solo 15 especies
se han señalado del Norte de Dobrudzha, mientras que en el sur su
conocimiento es mucho menor. Como resultado de este estudio, junto con
los datos previos existentes en la literatura, se señalan 17 especies
(cerca del 285 de la fauna de opiliones de Bulgaria) del área meridional
de Dobrudzha. Doce de ellas representan nuevas citas para esta zona (Nemastoma
bidentatum sparsum, Carinostoma elegans, Mitostoma gracile, Trogulus
tricarinatus, T. closanicus, Dicranolasma giljarovi, Phalangium opilio,
Zachaeus cf. anatolicus, Egaenus convexus, Lacinus horridus, Odiellus
lendli, Astrobunus laevipes). De esta zona y de sus regiones
adyacentes se han registrado 18 especies de opiliones, cuatro de ellas (Trogulus
closanicus, Dicranolasma thracium, Rilaena buresi, Eudasylobus beschkovi)
son nuevas citas para esta región. Se aportan datos sobre el número de
especies esperadas, el número de endemismos y su estado de conservación.
Mediante un dendodrama se ilustra la similitud faunística de Dobrudzha
Septentrional y Meridional, así como de sus regiones adyacentes y de
Sofia Kettle. |
