Acta entomologica serbica, 2015, 20: 59-66 UDC 595.773.1(497.11) NEW RECORDS OF THE GENUS CALLICERA PANZER, 1806  (DIPTERA: SYRPHIDAE) FROM SERBIA ZORICA NEDELJKOVIĆ1*, MARIJA MILIČIĆ2, LAURA LIKOV2,  SNEŽANA RADENKOVIĆ2 and ANTE VUJIĆ2 1 BioSensе Institute - Research Institute for Information Technologies in Biosystems Dr Zorana Đinđića 1, 21000 Novi Sad, Serbia *E-mail: zoricaned14@gmail.com 2 University of Novi Sad, Faculty of Sciences, Department of Biology and Ecology Trg Dositeja Obradovića 2, 21000 Novi Sad, Serbia Abstract Only one species of the genus Callicera Panzer, 1806, Callicera aenea (Fabricius, 1777), has been recorded in Serbia so far. In addition to the recurring detection of this species, the first records of Callicera aurata (Rossi, 1790) and Callicera spinolae Rondani, 1844 are documented. Based on the collected and studied material, the distribution maps and identification key for Serbian species are provided. KEY WORDS: Callicera aurata, Callicera spinolae, distribution, Serbia, identification key. Introduction With about 6000 described species, hoverflies (Diptera: Syrphidae) represent one of the most species-rich dipteran families. About 1800 species were recorded in the Palaearctic region (Van Veen, 2004). Hoverflies are significant pollinators of many plant species, and 19% of all insect pollinators are from the family Syrphidae (Rotheray & Gilbert, 2011). The genus Callicera Panzer, 1809 belongs to the subfamily Eristalinae, tribe Callicerini (Thompson & Rotheray, 1998). Callicera comprise robust bee-mimicking species, with very long antennae with arista posted at the apex of the third antennal segment. DOI: 10.5281/zenodo.4538960 Z. NEDELJKOVIĆ et al.  The distribution of Callicera species is limited to the Holarctic and Indomalayan regions. Most Palaearctic Callicera species inhabit southern (mainly Italy) and central Europe (Zimina, 1987). Zimina (1987) has revised the Palearctic species of this genus and recorded 10 species.  In the revision of the European species of this genus, Speight (1991) recognized six species: Callicera aenea (Fabricius, 1777), Callicera aurata (Rossi, 1790), Callicera fagesii (Guerin-Menéville, 1844), Callicera macquartii Rondani, 1844, Callicera rufa Schummel, 1842 and Callicera spinolae Rondani, 1944.  Smit (2014) described two new species of this genus, Callicera exigua from Altay Mountains (Russia) and C. scintilla from Jordan. So far, only one species from the genus, Callicera aenea, has been recorded in Serbia (Nedeljković et al., 2009).  Larvae of species from the genus Callicera are saproxylic and their development is connected to ancient Fagus/Quercus forests (Speight, 2014). Callicera adults prefer the same habitats, as well as Pinus forests with over-mature trees (Speight, 2014). Species are typically arboreal, but descend occasionally to drink water and feed (Speight, 2014).  The aim of this study was to complete the faunistic knowledge of the genus Callicera in Serbia by examining newly collected specimens deposited in the collection of Department of Biology and Ecology of University of Novi Sad (FSUNS).   Material and Methods  The examined material comprises adult specimens collected by sweeping net in the period 2009-2015. The material is deposited in the entomological collection of the Department of Biology and Ecology, University of Novi Sad, Serbia (FSUNS).  Identification was based on morphological characters of adults according to the key of Speight (1991). The identification key and distribution maps for Serbian species are provided. Maps were obtained using DivaGis software, version 7.5 (Hijmans et al., 2012a, b).   Results  The study of the collected material resulted in the identification of three Callicera species in Serbia − C. aenea, C. aurata and C. spinolae, with the findings of the last two species representing the first records for Serbia.  All Callicera species recorded in Serbia share the following morphological characters: antennal segment 3 about as long as segments 1+2 together; antennal segment 2 not less than 3/4 the length of antennal segment 1 (Fig. 1a, b).

Distribution: So far, the species was reported from Norway, Sweden, Poland, Czech Republic, France and different parts of Germany through central Europe into the Jura Mountains, the Alps (Switzerland, Austria) and Serbia (Speight, 2014). Zimina (1987) also reported its occurrence from European parts of Russia, south to the Crimea and east into Siberia and on to the Pacific (Sakhalin).

Discussion  The results of the present study confirm the occurrence of the species C. aenea and reveal for the first time the existence of two other species of the same genus (C. aurata and C. spinolae) in Serbia.  Callicera aenea has been recorded only at one locality, Popovica in the Fruška Gora National Park. This area is characterized by ancient Quercus/Fagus forests. Fruška Gora is very rich in hoverflies, with more than 210 registered species (Šimić et al., 2009). The relatively high number of recorded saproxylic species − 36 (Radenković et al., 2013), indicates that forests are well preserved in this national park. Larvae of this species breed in rot-holes on Fagus (Rotheray, 1993).  Callicera spinolae has been recorded in the Đerdap (Iron Gate) National Park and in southern parts of Serbia (natural landscape Pčinja), while Callicera aurata has so far been found only on Mt. Kopaonik. The presence of species of this genus at only a few localities in Serbia, all of them belonging to protected areas, is a strong indicator that species from this genus are rare and that they should be added to the list of protected and strictly protected species of hoverflies in Serbia (Strictly Protected Wild Species of Plants, Animals and Fungi, Official Gazette of RS, no. 5/2010 and 47/2011). a b The genus Callicera Panzer, 1806 in Serbia 65  The protection of Callicera species could be an additional argument for the conservation of some localities in national parks in Serbia. These species are typically connected to old trees (Speight, 2014) and their presence could be considered as an indicator of the well-preserved status of forests.  In light of the above, further studies of species of the Callicera genus, as well as a revision of the list of protected and strictly protected species, are much needed.
