Previous records: Coimbra (BACELAR, 1928;BACELAR, 1932); Guarda, Setúbal, Cabo Espichel, Sagres, Lagos, Faro, Tavira, Castro Marim (FRADE, BACELAR, 1931;BACELAR, 1932); Ramalhais, Fátima (MACHADO, ...

... The genus Iberesia was created to receive species from Nemesia that lack the posterior median spinnerets and, therefore, have only the posterior lateral spinnerets. Iberesia is currently composed of four species that show different regional distributions: Iberesia machadoi Decae & Cardoso, 2005, the type species, is found in Portugal and southwestern Spain (Cardoso 2000;Decae & Cardoso 2005;Decae, Cardoso & Selden 2007); I. brauni (Koch, 1882) occurs in the Balearic Islands (Koch 1882;Decae 2005); I. castillana (Frade & Bacelar, 1931), described from a single male specimen, was found in the northern sub-plateau of the Iberian Peninsula (Frade & Bacelar 1931, Decae & Cardoso 2005, and I. barbara (Lucas, 1846), senior synonym of Nemesia vittipes Simon, 1911, occurs in Morocco and Algeria (Lucas 1846;Simon 1911;Zonstein 2016). This work describes a new species, I. valdemoriana n. sp., that occurs in the southern sub-plateau and in the southeast of the Iberian Peninsula. ...
... However, it is necessary to be cautious again, since the sample of I. brauni studied in this work shows some variation in both the embolus base width and in the number and development of subdistal denticles (2−3 teeth ranging from barely visible to clearly visible). As in other nemesiids, spine patterns in these species are highly variable, even within the same individual, so it is not a useful diagnostic character (Blasco 1986;Cardoso 2000;Decae 2005). Nevertheless, patellar formulae, characters of recognized diagnostic value in Nemesia (Decae 2005;Decae & Cardoso 2005;Decae, Cardoso & Selden 2007), are useful to differentiate the males of I. valdemoriana n. sp. ...

The entire structure is uniformly covered by glandular tissue, except for the part that connects the collar to the receptacle (Cardoso 2000 covered with dense glandular tissue and less densely in the receptacles.

This paper describes a new species of trapdoor spider from the
Spanish mainland, Iberesia valdemoriana n. sp., and provides
some data about its natural history. The presence of both I.
brauni (L. Koch, 1882) and I. barbara (Lucas, 1846) is reported
for the first time in the south-east and south of the Iberian
Peninsula, respectively. An update of the key to the species
currently described of the genus based on the previous literature
and the results of present work is proposed.
... CLASPER-FIELD: zone with specialised short setae, often in species specific setting, on the ventral metatarsus I of males (Fig. 6). DESCRIPTIVE FORMULAE AND RATIOS Spine patterns are variable and difficult to interpret unambiguously in Nemesiini, and have therefore been of minor use in systematic descriptions of this group (Blasco, 1986;Cardoso, 2000;Decae, 2005). However, the patellar spine patterns can be interpreted relatively unambiguously and therefore are of taxonomical value, particularly if the observed variation can be summarised in a short formula. ...

The occurrence of the trapdoor spider family Nemesiidae in Portugal is reviewed on the basis of recently collected material. The new sample of well over a hundred specimens (of which 97 were used for description) collected from locations throughout the country, contains six different species, five of which we classify in the genus Nemesia, and one species that we place in the recently erected genus Iberesia. Three species, N. athiasi, N. fagei and N. unci-nata, could be recognised from descriptions in the literature although no type material was found. New information and figures of these species are provided. Two species, N. bacelarae sp. n. and N. ungoliant sp. n. are newly described and illustrated. A description of the female of N. uncinata and extended information on Iberesia machadoi are presented for the first time. The Portuguese species list is discussed and updated.
