NEW SAWFLIES FROM SPAIN (HYMENOPTERA, TENTHREDINIDAE)

Dolerus varispinus Hartig, 1837; Nematus respondens Förster, 1854; Pristiphora kamtchatica Malaise, 1931 and Pristiphora nievesi sp. n. are recorded from Spain for the first time. The description of Pristiphora nievesi sp. n. is given and compared to P. subbifida (Thomson, 1871); P. carpentieri Konow, 1903 and P. parnasia Konow, 1902.


Introduction
In February 2004, the author studied the sawfly material of the Museo Nacional de Ciencias Naturales, Madrid under the grant of a BIODIBE-RIA project.Two subfamilies of the real sawflies (Tenthredinidae) were selected to process, namely Nematinae and Dolerinae.
According to the interpretation of Zombori, (1982), the subfamily Nematinae, consisting mainly of small sawflies, 3.0-7.0mm, is characterised by a complete radial cell, which is not divided by a radial cross vein.Their cuticle is weekly sclerotised, soft.The Nematinae fauna is poor in the Mediterranean region, reaching its greatest diversity in the Scandinavian and Siberian regions.
The characteristic feature of the subfamily Dolerinae is the missing 2nd cubital cross-vein resulting in a very elongated second cubital cell.
The first check-list of Spanish sawflies was published by Ceballos, (1956).Liston also referred to Spanish sawflies in the Compendium of European Sawflies in 1995.He enumerated 245 sawfly species from Spain which is relatively poor compared to northern countries.On the other hand, the Iberian peninsula is rich in endemic species.32 species (including the new species described in this paper) are known to occur only in the Iberian Peninsula.

Matherial and Methods
Approximately 600 specimens of subfamilies Dolerinae and Nematinae were identified.For the identification of Nematinae, the most useful and comprehensive handbook is that written by Zhelochovtsev (1988) which includes about 95% of the total European fauna.For the identification of the Dolerinae fauna, papers by Llorente (1988), Haris (2000) and the revision of Blank and Taeger (1992) were used.The genitalia dissection and study, especially in males, is inevitable in these groups.The necessary genitalia figures are available in the above mentioned papers.The sawsheath structure of females is clearly visible without any dissection.The saw preparation can easily destroy specimens, and was therefore not used.The following features were studied during the identification process: colour, sawsheath-structure, penis valve-structure, surface sculpture, teeth of claws and relative ratios of the body.
COMMENTS.The new species is related to Pristiphora subbifida (Thomson, 1871); P. carpen- tieri Konow, 1903 andP. parnasia Konow, 1902.All of these species have bifid or subbifid claws which is a very special feature of the genus.Abdomen extensively or entirely yellow above and beneath.Most of them are richly coloured with yellow on the mesopleuron or if the mesopleuron is black at least their pronotum -partly-, tegulae and orbits are yellow, except in the new species, which has an entirely black thorax and head.All of them have a deeply emarginated sawsheath (Fig. 1) except the new species in which the sawsheath is truncate, subtruncate apically (Fig. 2).For a comparison of females see in the key below.

Key of females of Pristiphora subbifida group
Pristiphora subbifida group: claws always bifid, subbifid, abdomen yellow above and beneath, sometimes black spots may occur on the tergites.Hind legs are at least partly light coloured.Stigma black or dark brown.
