INTRODUCTION In recent years, from 2000 to 2015, there has been an increasing number of entomologists collecting and studying Hymenoptera in Portugal. The main record- ers have been Alain Livory, Roselyne Coulomb and David Baldock; all the other colleagues are mentioned in the acknowledgements. Thanks to this teamwork, about 1200 species of Hymenoptera and 70 species of Chrysididae have been recorded in Portugal, raising the number of known Portuguese species and subspecies to 162 (Mingo, 1994; Kuhlmann, 1996; Tussac & Zumeta, 2004; Oliveira, 2009; Rosa & Soon, 2012; pers. data). The new chrysidid records for Portugal will be dis- cussed in a separate paper, but one species is worthy to be mentioned apart, because it has not been found pre- viously from Europe and it is one of the most outstand- ing species in the West Palearctic. Chrysis monticola Linsenmaier, 1999 was recently described for northern Africa (Morocco and Algeria); Alain Livory and Rose- lyne Coulomb collected some specimens for the first time in Europe from 2009 to 2012. �fter this discovery, the number of chrysidid European species is raised from 483 (Mitroiu et al., 2015) to 484. MATERIALS AND METHODS The terminology follows Kimsey & Bohart (1991), and the classification of species and species groups fol- low Fauna Europaea (Rosa & Soon, 2012), Linsenmaier (1959, 1999). �bbreviations used in the text are as fol- lows: F1, F2, etc. = flagellum 1, flagellum 2; l/w = length versus width; MOD = midocellus diameter; OOL = oculo-ocellar line; POL = postocellar line; S2 = second metasomal sternite; T1 = first metasomal tergite; T3 = third metasomal tergite; TFC = transverse frontal carina. Photographs of the specimens were taken with a Nikon D80 camera connected to a Togal SCZ stereomi- croscope and stacked with Combine ZP software. The white calibration of the camera was applied to reduce the blue effect of the neon light of the Togal micro- scope. RESULTS Examined material Chrysis monticola Linsenmaier was collected in Por- tugal in Algarve and Baixo Alentejo by A. Livory and R. Coulomb (Fig. 1). �lgarve: 1♀, Carrapateira, vii.2009 (Fig. 2�) (P. Rosa collection); 1♂, Odeceixe (�ljezur), 90 vii.2009 (Fig. 2B) (P. Rosa collection); 1♂, id., vii.2009; 1♀, id. 26.vii.2009; 1♀, id. 26.vii.2009 (�. Livory and D. Baldock collections). Baixo �lentejo: 1♂, Zambujeira do Mar, 17.vii.2012 (�. Livory collection). Description of Chrysis monticola Linsenmaier, 1999 Female: 7-8 mm (6-7 mm in the original description) (Fig. 3A). Colouration: head metallic blue, frons and vertex in ocellar area greenish; pronotum, scutellum, meta- notum mesopleuron, metapleuron and partially propo- deum metallic red to golden-red; metasoma metallic red, T1 anteriorly metallic blue to greenish; antennae blackish, with very feeble blue metallic ref lections on pedicellus and base of F1. Head: malar spaces more subparallel than in Linsenmaier line drawing (Linsen- maier, 1999: 170, fig. 224) and about 1.1 MOD long (Fig. 3B); subantennal space a little longer than 1 MOD; OOL: 2.3 MOD; POL: 2.2 MOD; TFC distinct and vaguely M-like; scapal basin medially micro- punctate, with punctures conf luent and forming trans- versal lines; clypeus medially slightly incised. Meso- soma: with large punctures and smooth intervals (Fig. 3C), propodeal tooth narrow and pointing downward. Metasoma: apical teeth elongated (Fig. 3D) and spini- form, the median pair close together and the lateral well developed and pointed; pit row with relatively large and deep pits, the two median pits larger, later- ally partially fused; black spots on S2 large (Linsen- maier, 1999: 170, fig. 227). Male: 7-8 mm (Fig. 4). Differs from female by col- ouration: the red and golden parts of mesosoma are Fig. 1 - Map of the collecting localities of Chrysis monticola in south- ern Portugal. Fig. 2 - Chrysis monticola Linsenmaier, 1999. European specimens: A) female, B) male. greenish, contrasting with the rest of head and mes- onotum. In both sexes there are two greenish to bluish rounded spots laterally on pronotum. Malar spaces evi- dently convergent and about 1.1 MOD long; TFC dis- tinctly M-like; scapal basin micropunctated, with long whitish hairs; apical teeth shorter and smaller, with sub- equal intervals. Variation and species group placement The European female (Fig. 2A) differs from the northern African female by narrower apical teeth and larger black spots on S2. The male (Fig. 2B) differs by pale femur and enlarged black spots on S2. Despite these small differences, the genital capsule match the genitalia of the allotype from Morocco and therefore we consider the discrepancies as intraspecific variations between dif- ferent populations. Future molecular systematic analysis will possibly confirm this interpretation. The Algerian paratype housed in the Linsenmaier collection is truly a little different, as already noticed by Linsenmaier (1999). In particular, the very reduced black spots on S2 are remarkably different. However, this vari- ation could be related to the different environmental con- ditions, whereas the genital capsule matches the genital capsule of the Moroccan allotype. Linsenmaier (1999) noticed that C. monticola could be included in the C. viridula group. We maintain the place- ment of C. monticola in the C. aestiva group for its gen- eral habitus, the shape of the genital capsule and other diagnostic characteristics of the species group despite its unusual and unique body colouration.

CHRySIS MONTICOLA LINSENM�IER, 1999 (HyMENOPTER�, CHRySIDID�E), � NEW SPECIES FOR THE EUROPE�N F�UN� 92 Distribution Chrysis monticola Linsenmaier, 1999 is known from northern Africa (Morocco and Algeria) and Portugal. Based on the known records, C. monticola is a euryther- mic and euryzonal species living in high mountains (it was collected at 1900 m) and deserts (Tamanrasset). Phenology Chrysis monticola in Portugal was recorded only in July, although field research was carried out throughout the season between March and the end of September. It is likely that July is the optimal period of flight of C. monti- cola in Portugal. In northern Africa, it has been recorded in the High Atlas and Anti-Atlas mountains in Morocco (Tizi-n-Test, Timahdite, Ijoukak, Ait Saoun) from June to July, and in Algeria (Tamanrasset) at the end of March. Biology and habitat Chrysis monticola Linsenmaier was collected in three localities from North to South of the coast between Cabo de Sines and Cabo de Sao Vicente, in the Parque Natu- ral do Sudoeste Alentejano e Costa Vicentina, the larg- est protected coastal area in Europe, more than 100 km long. The landscapes consist of rocky capes, steep or broken cliffs, interspersed with immense dunes or estuar- ies. These habitats conceal many endemic plants and the fauna is extremely rich. One specimen was collected on the cliffs of Zambujeira do Mar in Alentejo (Fig. 5), in a habitat of dunes and scrubland. Most of the specimens were collected further south, on the banks of the Ceixe estuary at Odeceixe, together with many other rare Hy- menoptera species. Here the dunes perched on cliffs offer a diversified network of scrubland and mobile sands that is extremely attractive to aculeate Hymenoptera. Lastly, one specimen was collected at the extreme south of Al- garve, in the immense stretch of dunes of Carrapateira (Fig. 6) with its enormous clumps of Eryngium mariti- mum. The specimens were collected on the ground or on flowers but possible hosts were not observed. The only ci- tation (Linsenmaier, 1959) in this species group for Medi- terranean species is Pseudoanthidium lituratum (Panzer) (Megachilidae), as a possible host for Chrysis interjecta du Buysson.

PAOLO ROSA, ALAIN LIVORY, DAVID BALDOCK 93 Diagnosis of the C. aestiva group Chrysis monticola Linsenmaier, 1999 belongs to the C. aestiva group. The Chrysis aestiva group was origi- nally established by Linsenmaier (1959) and it is charac- terised by: rather long F1 (l/w in male: 2˗2.8, in female: 2.4˗2.8), face usually microridged medially, in some species basomedially polished in female; TFC partial, with an M-like form, usually strongest medially; malar space long, in male about 1.2 MOD, in female about 2 MOD (less than the measures given in Kimsey & Bohart, 1991); propodeal angle short, stout, blunt, straight or gently incurved behind; last tergite not saddled, pit row developed, but usually simple, without large pits; apical margin of T3 with four short teeth, usually the median pair a little longer and closer together, lateral pair weak or absent; S2 with two large black spots, sometimes fused or nearly so. Members of the Chrysis aestiva group are found in the western Palearctic region (15 species and 8 subspecies), and in the Afrotropical region (2 species). They are most- ly distributed around the Mediterranean countries, Middle East and West Asia. At present: - six species and two subspecies are known for the European fauna: Chrysis aestiva aestiva Dahlbom, 1854 (= C. quadrimaculata Bischoff, 1910), C. interjecta inter- jecta du Buysson (in �ndré), 1895 (= C. rosina Balthasar, 1953), C. interjecta hemichlora Linsenmaier, 1951, C. maderi Linsenmaier, 1959, C. martinella patrasensis Lin- senmaier, 1968; C. mixta Dahlbom, 1854; C. monticola Linsenmaier, 1999 (Rosa & Soon, 2012); - nine species and three subspecies are known for Middle East and West Asia: C. aestiva aestiva Dahlbom, 1854, C. aestiva moczari Linsenmaier, 1959, C. andreevi Semenov, 1954, C. antakyensis Linsenmaier, 1968, C. au- relia aurelia Balthasar, 1953, C. aurelia palmachinensis Linsenmaier, 1987, C. gusenleitneri Linsenmaier, 1968, C. iocosa Linsenmaier, 1968, C. martinella martinella du Buysson, 1900 (= C. satunini Semenov, 1967), C. mar- tinella solox Semenov, 1954 (= C. klapperichi Balthasar, 1957), C. mirifica Balthasar, 1953, C. sardarica sardarica Radoszkowski, 1890; - five species and three subspecies are known for north- ern Africa (C. caudex Linsenmaier, 1968, C. denticula Linsenmaier, 1999, C. interjecta mediana Linsenmaier, 1987, C. monticola Linsenmaier 1999, C. sardarica per- recta Linsenmaier, 1959, C. sardarica lepidula Linsen- maier, 1959); - two species are recorded from South Africa and Madagascar (C. grootdermensis Koch, 2006 and C. ma- decassa Mocsáry, 1908). Chrysis amurensis Semenov, 1967 was included by Kimsey & Bohart (1991) in the C. aestiva group but, after type examination, it does not share the diagnostic charac- teristics of the species group and we transfer it into the C. splendidula group. The Iberian species of the C. aestiva group Before this study, only two species of the C. aestiva group were known from the Iberian Peninsula: Chrysis in- terjecta du Buysson and C. mixta Dahlbom (Mingo, 1994). However, C. interjecta is not yet recorded for Portugal, whereas C. mixta seems to be very common in central and southern Portugal (Mingo & Gayubo, 1985; Oliveira et al., 2009). Except for an old record from Sines (Lisbon) 15.viii.1956, leg. N. F. d’�ndrade (Natur Museum, Lu- zern, CH), all the records of C. mixta are recent and from Costa Vicentina: �lgarve: Guia, 17.v.1999, 1♂, leg. Bald- ock; 1♀, �ljezur, Odeceixe, 1.ix.2008, 1♀, vii.2009, and 1♂, 27.v.2011, leg. �. Livory & R. Coulomb; 1♂, Pera, Vila do Bispo, 25.ix.2014, leg. I. Cross; 2♀♀, Carrap- ateira, 14.ix.2014; 2♀♀, 19.ix.2014, leg. �. Livory & R. Coulomb; �lentejo: 1♂, Zambujeira do Mar, 17.vii.2012; 1♂, leg. �. Livory & R. Coulomb; 1♀, Vila Nova de Mil- fontes, 20.ix.2014, leg. �. Livory & R. Coulomb. The distributional range of C. mixta is SW European, being distributed only in southern Portugal, Spain, south- ern France and northwestern Italy (Linsenmaier, 1959; Rosa & Soon, 2012). Other citations outside this range are referable to other similar species (e.g. Chrysis maderi Linsenmaier, 1959). Chrysis monticola Linsenmaier is easily recognizable within this species group, and more generally, within the European chrysidid fauna by its unique body colouration combined with diagnostic characteristics of the group. A similarly coloured European species is Chrysis judaica du Buysson (scutellaris group), known only from Cyprus, whereas in northern Africa and Middle East other species share a similar colour pattern, but belong to different spe- cies groups (e.g. C. moriceana du Buysson – scutellaris group; C. convexianalis Linsenmaier – facialis group).

C. interjecta DISCUSSION AND CONCLUSIONS Chrysis monticola Linsenmaier was recently described by Linsenmaier (1999) from northern �frica based on a type series of seven specimens. Until now, no other specimens have been found from the main European col- lections. Therefore, we cannot evaluate if this species has CHRySIS MONTICOLA LINSENM�IER, 1999 (HyMENOPTER�, CHRySIDID�E), � NEW SPECIES FOR THE EUROPE�N F�UN� 94 recently dispersed to Portugal from northern Africa or if its original distributional range has been wider in west Mediterranean countries and is now limited to the west Iberian Peninsula and North Africa. It is very likely that C. monticola could be also distributed along the coast of Andalucia, Spain.
