Two boverfly species {Diptera, Syrphidae) new to the province of Barcelona

Dos especies de sirfidos (Diptera, Syrpbidae) nuevas para la provincia de Barcelona

The first records of Callicera aura/a (Rossi, 1790) and Sy1phus torvus Osten-Sacken, 1875 from the province of Barcelona (Spain) arc provided. A female of C. azu-ata and 11 specimens of S. torvus (71313, 4 ~~ ) were collected in Santa Fe, El Montseny Biosphere Reserve, Fogars de Montclus, with cross traps (Econex® model) to sample saproxylic beetles (Coleoptcra), by Eduard Piera i Pallas. Callicera aura/a was collected between 14/07/2018 and 01 /08/2018, whileS. torvus between 0110612018 and 13/07/ 2018. DMS coordinates and altitude (m asl) of sampling localities are as follows: for Callicera aura/a, l) 41° 46' 41.9" N, 02° 27' 24.3" E, 1171; for torvus: 2) 41° 46' 41.7" N, 02° 27' 23.9" E, 1170; 3) 41" 46' 42.2" N, 02" 27' 25.0" E, 1170; 4) 41" 46' 46.7" N, 02° 27' 25.5" E, 11 76; 5) 4 1" 46' 42.8" N, 02" 27' 23.9" E, 1170; 6) 41" 46' 45.8" N, 02" 27' 25.2" E, 1178; 7) 4 1" 46' 41.9'' N, 02° 27' 24.3" E, 1171. Other hoverny species collected in El Montscny, between June-August 2018, in the same sampling as C. aurMc1 and S. torvus arc: Episyrphus balteaws (de Gccr, 1776) (l o : 4 1° 46' 43.7" N, 02• 27' 30.1 '' E, 1161), Eristalis tenax (Linnaeus, 1758) (I d': 41" 46' 43.7" N, 02" 27' 30.1 " E, 11 61), Myatllropaflorea (Linnacus, 1758) (3

Boln Asoc. esp. Ent., 42 (3 -4): 457-459, 26-12-20 18 458 ANTONIO RICARTE and EDUARD PIERA I PALLAS from Cabaiieros National Park, Ciudad Real, Spain. QU INTO et al. (2014) reported again C. aurata in mixed woodlands of Quercus pyrenaica Willd. and Q. faginea at the same locality of Ciudad Real. The species is not re­ corded from Portugal {VAN ECK, 20 I I, 20 16). Callicera auraw together with Callicera fagesii Guerin-Meneville, 1844, which is only known from Cadiz too (SPEIGHT, 1991), are the two most poorly recorded species of Ca!licera in Spain (RI CARTE & MARCOS-GARCiA, 20 I 7). Our record o f C. aurata is the f irst from the northern half of the Iberian Peninsula. This Calli cera species might be separated from the other European species of the gen us by the following combination of characters: length of second ante nna! segment at least three quarters the length of first antenna! segment; third antenna! segment about as long as first plus second; femora extensively black (females); thoracic scutum with two vittae of pollinosity medially; pile on scutellum nowhere as long as the scutellum; tarsomeres 3-5 of all legs black or nearly so (SPEIGHT, 199 1). Syrphus torvus is recorded from Andorra and from 11 of the 50 Spanish provinces. After Syrplws nitidifrons Seeker, 1921, which is recorded only from Lleida, S. torvus is the Syrphus species present in the lowest number of Spanish provinces (RI CARTE & MARCOS-GARCiA, 2017). Furthermore, S. torvus is not recorded from Portugal so far (VAN ECK, 2011, 2016). This species can be readily separated from the other European species of Syrplws by the second basal cell of its wing being entirely microtrichose and its distinctly pilose eyes, which, however, have shorter hairs in females than in males (SPEIGI-IT & SARTHOU, 2017). The province of Barcelona had I 07 hover species recorded (RI CAR­ TE & MARCOS-GARCiA, 2017) and now the number increases to 109. Callicera aurata is a species with larvae living in rot holes of trees such as beech (Fagus sp) in ancient forest (ROTHERAY, 199 1), whileS. torvus has larvae preying mainly on (Hemiptera: Aphididae) feeding on many plant species such as Rubus idaeus L., in Poland, and Abies saclwlinaensis (F.Schmidt) Mast., in Japan (ROJO et al. , 2003). The vegetation in our study area is an acidophilus beech forest (Fagus sylvatica L.) mixed with Abies alba Mill. and other trees, and some clearings domi nated by plants such as Rubus sp. (SAEZ et al., 2017). The presence of the saproxylic C. Clurc1ta indicates ancient beech forest or at least old Fagus trees in the sur­ veyed area of El Montseny, and the larvae of S. torvus may be feed ing on aphids of Abies and Rubus. A good knowledge of the species requirements enhances both species and habitat conservation.
