New records of Muscidae (Diptera) from Mediterranean countries.

New records are provided for Muscidae from four different Mediterranean countries, with new distribution records for species in ten different genera. Seven species are newly recorded for Croatia, four species for Montenegro and one species for Bosnia & Herzegovina. In this paper we give the first confirmation of an aquatic larval stage for Lispocephalabrachialis (Rondani, 1877), Lispocephalaspuria (Zetterstedt, 1838) and Lispocephalamikii (Strobl, 1893). A first record of the species Coenosialyneborgi Pont, 1972 since its original description is also provided.

Introduction

Muscid flies are one of the largest groups of in Europe, with approximately 600 species (Oosterbroek 2006). The family comprises seven subfamilies among which the subfamily , commonly known as “hunter flies”, is entirely predaceous in both the larval and adult stages. Larvae of the other subfamilies may be predaceous or saprophagous in decaying organic matter, while most adults feed on nectar. Some adults feed on blood or on the tissues of wounded animals (flies of the PageBreaksubfamilies and ) and they are facultative vectors of diseases (Oosterbroek 2006, Gregor et al. 2002).

In this paper new records of various genera of collected from a number of different localities in the eastern Mediterranean and from localities in the Sierra Nevada, Spain, are offered. The fauna of from the Mediterranean countries and especially from the eastern Mediterranean is poorly known and has not been sufficiently explored. Apart from the papers by Coe (1960, 1962a,b, 1968a,b) on the countries of the former Yugoslavia, the only recent paper involving the Balkan Peninsula is that by Pont and Ivković (2013) that deals with the genus Robineau-Desvoidy from some sites in Croatia. “Rearing” records from emergence traps are exclusively from Croatia, while the net-collected records are from different countries, including Croatia. The majority of records are of “hunter flies” as many of them have aquatic larvae and, as all the collecting took place around streams and river banks, the preponderance of these flies was to be expected.

Material and methods

In the course of various ecological and taxonomic projects and surveys by M.I., many muscid flies were collected by means of emergence traps set in streams and small rivers at five sites in Plitvice Lakes National Park and at two sites at Krka National Park, both in Croatia. Traps were emptied once a month, at the end of each month. Each trap had a surface area of 45 × 45 cm (and height 50 cm), was fixed in the sediment of the stream, and contained 2% formaldehyde; six traps were placed at each location (Fig. 1) and for additional details see Ivković et al. (2014). Each trap was recorded with the initial “P” and a number, e.g. “P5" is pyramid emergence trap no. 5. All flies were collected from March 2007 to October 2014. The occasional presence in the emergence traps of a species that does not have aquatic or semi-aquatic larvae is an anomaly that we cannot explain at present. It may be the result of fluctuations in the water level, allowing an adult fly or a drifting puparium to enter the trap. Such anomalies have been discussed by Malicky (2002).

Additional sampling using an aspirator and a sweep net took place between March 2011 and June 2014 at various localities in the eastern Mediterranean part of Europe and from April to June 2013 in the Sierra Nevada, Spain (western Mediterranean). All specimens were placed in 80% ethanol and sent to A.C.P. for identification. They were passed through 2-ethoxyethanol (24 hours) and ethyl acetate (24 hours), and then dried, mounted and labelled. Inevitably, many were freshly emerged and not fully hardened, but nevertheless almost every specimen could be identified to species. The monographs by Hennig (1955–1964), Gregor et al. (2002) and Pont and Ivković (2013) were used for identification. All the material listed here is deposited in the Natural History Museum, London, UK (BMNH) and the Oxford University Museum of Natural History, Oxford, UK (OUMNH). GPS coordinates and altitudes for the localities where specimens were trapped and/or collected are given in Table 1.

Tribe

Robineau-Desvoidy, 1830

Remarks.

A large genus, found in all biogeographic regions. There are 27 species in Europe of which 13 are known from the Balkan Peninsula. Species of the genus are usually associated with clean water courses (Rozkošný and Gregor 2004) although Skidmore (1985) writes that (Fallén) can tolerate high levels of pollution. Both adults and larvae are predaceous (Werner and Pont 2006). The larvae of many species are found among aquatic mosses in streams and rivers (Rozkošný and Gregor 2004). A key to Croatian species, with four new records and one new species, was given by Pont and Ivković (2013).

Adults are predaceous and can be found around standing and running water, where they actively hunt other small invertebrates even in hot, sunny, open habitats (Werner and Pont 2006). Larvae are semi-aquatic and also predaceous, living in organic sand and mud (Skidmore 1985).

A small genus in Europe with only 12 species, six of which are known from the Balkan Peninsula. Adults are predaceous on other small insects. No larvae of the European species have been described, but it was suspected that they would be aquatic as the adults are usually found in the vicinity of running water. This is confirmed by the records of the three species given here, all of which were caught in emergence traps set in the water.

This species was described from Croatia and is a Mediterranean and Afrotropical species. This is the first confirmation of an aquatic life-cycle for this species.

(Zetterstedt, 1838)

CROATIA: spring of Bijela rijeka, Plitvice Lakes, vii.2012, emergence trap P6, 1♀.

Throughout the Palaearctic region, but an uncommon species. This is the first confirmation of an aquatic life-cycle for this species. New for Croatia.

Stein, 1919

Only two species of are known, and an Afrotropical species doubtfully referred to this genus.

(von Roser, 1840)

CROATIA: Roški Slap, Krka River, 6.xi.2013, emergence trap P4, 1♀.

Nothing is known of the biology of this species but the present rearing indicates that the larvae are aquatic. Throughout Europe, and also in East Africa. New for Croatia.

Discussion

The PageBreakFauna Europaea site for the family (Pont 2005) has not been updated since it first went online, and over the past decade a number of new records have been published, new material has been identified by A.C.P., and records in some of the older publications have been re-assessed. For this reason some of the records presented in this paper are not actually new even though they do not appear on the Fauna Europaea site. Moreover, the Fauna Europaea website did not separate Serbia and Montenegro (Pape et al. 2015).

Including the new records given here, current totals for the countries of the former Yugoslavia are as follows:

Bosnia-Herzegovina: 45 (11 in Fauna Europaea)

Croatia: 91 (79 in Fauna Europaea)

Slovenia: 93 (85 in Fauna Europaea)

Macedonia: 39 (39 in Fauna Europaea)

Serbia: 45

Montenegro: 17 (89 in Fauna Europaea for Serbia and Montenegro combined)

For comparison, 138 species are known from the Greek Mainland and 258 from Spain. It is evident from these figures that much remains to be discovered about the muscid fauna of the Balkan Peninsula, and areas of mountainous and/or temperate broad-leaf forest should prove to be particularly rich in biodiversity.
