Abstract: |
|
| |
|
A new genus,
Iberesia, is formed to receive species endemic to the Iberian
Peninsula tratitionally included in Nemesia Audouin, 1826, but to
be distinguished by the absence of posterior median spinnerets.
Iberesia includes I. machadoi sp. n., the type species which
is widely distributed in Portugal as well as two species transferred
from Nemesia: I. brauni (Koch, 1882) comb. n. from the
Balearics and I. castillana (Frade & Bacelar, 1931) comb. n. from
Avila, central Spain. We group Iberesia with Nemesia and
Brachythele in the tribe Nemesiini Raven, 1985. The characters on
which this grouping is based are discussed. Also discussed is the
taxonomic confusion about the identity of Nemesia hispanica (L.
Koch, 1871) in relation to that of I. machadoi sp. n. The type of
Nemesia hispanica is considered to be and adult female. |

Resumen: |
|
| |
|
Se describe un nuevo
género que agrupa especies endémicas de la Península Ibérica que
tradicionalmente estaban incluidas en el género Nemesia Audouin,
1826, aunque carecen de las hileras medianas posteriores. El género
Iberesia incluye I. machadoi sp. n. especie ampliamente
distribuida en Portugal, y dos especies más transferidas del género
Nemesia: I brauni (Koch, 1882) comb. n. de Avila. Se propone
la agrupación de Iberesia, Nemesia y Brachythele dentro de
la tribu Nemesiini Raven, 1985, y se discuten los carácteres utilizados
para esta agrupación. Así mismo se comenta la confusión taxonómica sobre
la identidad de Nemesia hispanica (L. Koch, 1871) e I.
machadoi sp. n. Se considera que el Tipo de Nemesia
hispanica es una hembra adulta. |
