New species and records of Microphorella Becker (Diptera: Empidoidea, Dolichopodidae) from the Mediterranean region

Paul GATT 67 Triq Godwin Ganado, Tal Virtu, Rabat RBT 02, Malta. E-mail: paul.gatt @ global.net.mt

New species and records of Microphorella Becker (Diptera: Empi- doidea, Dolichopodidae) from the Mediterranean region. - Two new species of Microphorella Becker, M. ulrichi sp. n. from Morocco and Tunisia, and M. merzi sp. n. from Cyprus, Malta and Turkey are described. Two additional species from Turkey and Israel are not described because of inadequate material. M. curtipes (Becker) is newly recorded from Sardinia, and the genus is newly recorded from North Africa, Sardinia, Malta, Turkey, Cyprus and Israel.

Key-words: Diptera - Dolichopodidae - Parathalassiinae - Microphorella - new species - new records - Mediterranean region.

INTRODUCTION

Microphorella Becker is a little known genus of basal Dolichopodidae which, together with Parathalassius Mik, Amphithalassius Ulrich, Plesiothalassius Ulrich and Thalassophorus Saigusa, has tentatively been placed in a subfamily - Parathalassiinae Chväla 1981 - tentatively only, because the subfamily may be a paraphyletic assem- blage. Originally, the then known genera were included in the former Empididae. They were subsequently transferred to the Microphoridae when the Empididae was divided into four distinct families by Chväla (1981-1988). However, phylogenetic evidence is very strong that the Parathalassinae are more closely related to the Dolichopodidae s. auct. than to the Microphorinae, forming a monophylum with the former, not the latter (Ulrich, 1990, 1991 and in litt.; Cumming & Sinclair, 2000).

The genus, as currently defined, is known from 5 Nearctic (Melander, 1928), 1 Australian (Colless, 1963) and 3 Palaearctic (Chväla, 1988) species. More species, both extant and fossil, doubtlessly occur. Shamshev & Grootaert (2002) recently erected a new genus, Chimerothalassius, for a new species of the Microphorella group from New Zealand.

Likewise, two fossil species of Microphorella-like flies have recently been described from Baltic amber by Cumming & Brooks (2002) who erected a new genus, Electrophorella, for them.

Species of Microphorella are minute flies with inconspicuous habits, and are thus easily overlooked. Consequently, they are not commonly found in collections.

Manuscript accepted 03.06.2003

670 P. GATT

They have been collected by sweeping on sandy beaches, gravel and sand in river beds, and on moist rocks in streams. The small flies are very difficult to spot while resting on sand, and will only be caught if deliberate, slow, sweeping movements are employed, with the mouth of the net held very close to the ground.

The three Palaearctic species have been reviewed by Chväla (1988) who also figured male and female genitalia. They include M. praecox (Loew, 1864) from central and northern Europe, M. beckeri (Strobl, 1910) from Austria and northern Yugoslavia, and M. curtipes (Becker, 1910) from northern Italy and Corsica. The Palaearctic species known so far are therefore exclusively distributed in Europe from the Mediterranean in the south, north to the arctic circle (Chväla 1988, Fig. 1). Only one species, M. curtipes, is known from the Mediterranean (Corsica). Since that time, the genus has received scant attention. No new species have been described, and no new records have been added from the Mediterranean. It is therefore of interest to describe two new mediterranean species, and to record the genus for the first time from the coast of North Africa (Tunisia and Morocco), the mediterranean islands of Sardinia, Malta and Cyprus, and the mediterranean coasts of Turkey and Israel. A further two new species from Turkey and Israel are not described because of lack of adequate material.

MATERIAL AND METHODS

The material available for this study was collected in large part by the author. Valuable material was also contributed by Dr Bernhard Merz (Geneva), Dr Martin Ebejer (Cardiff) and Dr John Deeming (Cardiff).

Dissected specimens on which the drawings are based are stored in glycerine microvials mounted on pins in the author’s collection. Slide mounts of wings, antennae, and legs were prepared in Berlese fluid, as described by Disney (1983). Drawings were made with the aid of a x250 stereomicroscope and drawing tube. For some figures (Figs 2-3, 6-8, 11, 17, 21) a compound microscope with built in ocular grid was employed. Drawings of complex structures made from slide mounts studied in transmitted light (eg. Fig. 7) fail to make a clear distinction between internal and external structures, and cannot show how the various parts are interconnected.

The following abbreviations are used in the figures 1-21:

metrical, sternites reduced; postabdomen beginning with sternite 4, rotated and latero- flexed to the right, as in congeners; tergites 5 and 6 narrowed and excavated on the right hand side, accomodating hypopygium; tergite 7 normal, tergite 8 vestigial; sternite 4 broad, short, depigmented medially and indented at its hind margin. Sternite 5 (Fig. 6) short, brown and lustrous, modified, with a median, robust, keel-shaped process which is bifid in profile and projecting ventrad; sternite 6 (Fig. 6) broad and angular, more heavily pigmented in middle third; sternite 7 large, quandrangular in side view, dusted except for a polished, roughly triangular area on posterior half; sternite 8 large, clothed with long, white hairs.

Female

Resembling male in many respects. Body and wings generally longer; face wider, parallel sided; antennae darker, postpedicel less produced apically, stylus some- what longer; palpi brownish grey; legs more slender, darker, especially coxae; hairs shorter; pigmented spinulated tubercles overlapped by tibial combs present on fore and hind metatarsi as in male, but fore tarsus not dilated. Anteroventral fringe on apical three quarters of hind femur inconspicuous; hind femur without digitiform process. Posterior section (ie. that adjacent to M,) of cross-vein m-m reduced, and therefore cross-vein m-m incomplete, in one wing only, of each of two female specimens exam- ined. Abdomen (Fig. 9 and 10) of the ‘acanthophorous intruded’ type (Chväla, 1986), more dorsoventrally flattened, sparsely brownish dusted, shinier, terminalia shining black; hairs on tergites longer, darker, and more numerous. Segments 1-5 simple, form- ing preabdomen; tergite 5 with a hind marginal fringe of very long black bristles; postabdomen slender, retracted into preabdomen; tergites 6 and 7 butterfly shaped, an- teriorly more pigmented, and posteriorly with a few short spines near apices of lateral margins; tergite 8 completely or incompletely divided by a median cleft, deeply emar- ginate anteriorly, pale and weakly sclerotised posteriorly - when completely cleft, the medial borders of the two halves meet in the median line (as in Fig. 9). Tergite 10 cleft into a pair of hemitergites (acanthophorites), as in congeners, each bearing, at its pos- terior margin, 4 spines with rounded ends; the two medial ones long and thick, the two lateral ones less than half as long and correspondingly weaker. In dorsal view (Fig. 9), the 4 spines look like blunt pegs. In lateral view (Fig. 10) they appear flattened, pointed, and curved dorsad. Sternite 6 narrow, evenly pigmented, with some long, black hairs on posterior margin; sternite 7 longer, heavily pigmented on lateral margins but very pale centrally; ventral plate of segment 8 long, boat shaped, with distinct, short, longitudinal, parallel, pigmented ridges at tip; one spermatheca (Fig. 11).

Length. Body 1.9 mm, wing 2.6 mm

BIOLOGY This species has been collected from the marine coast (beach and dunes). It has also been swept from a wet meadow, a pine forest and an oak forest at altitude (900m)

and is therefore clearly not exclusively coastal in habitat. The spines of the female’s hemitergites 10 are shaped like curved gutters, suitable for digging into sand and sim- ilar soft substrates.

DISTRIBUTION

Hitherto known from the mediterranean coast of North Africa (Tunisia and Morocco).

REMARKS

This species can easily be distinguished from its Palaearctic congeners by the characters given under ‘diagnosis’. Other characters of taxonomic importance include: the black thoracic bristles; the short biserial acrostichals; the bristle-like, uniserial dor- socentrals; the two strong supra-alar bristles; and the conspicuous anteroventral fringe of long hairs on the male hind femur.

Pigmented spinulated tubercles have not hitherto been observed in any species of Microphorella. They are absent in the two Palaearctic species I have examined (M. praecox and M. curtipes). The modified fore tarsi and hind femora in the male of this species are also unique. Melander (1928) described dilated hind, but not fore, tarsi in the males of some Nearctic species of the genus.

Combs of spinules on fore and hind tibiae and on hind metatarsi may be more common in members of this, and related, genera, than has hitherto been appreciated. Melander (1928) and Chväla (1988) make no mention of this character in any of the species that they treat. Colless (1963), however, describes it in M. iota from Australia and Ulrich (1991) records it also in the parathalassiine genera Plesiothalassius and Amphithalassius from South Africa. Combs are present in the two Palaearctic species of Microphorella I have examined (M. praecox and M. curtipes).

Reduction of the base of vein M, is not rare as an individual aberration in species of Microphorella, both recent and fossil in Baltic amber (Ulrich, 2002). The base of M, though always complete, is pale in several specimens of this species. It is speculated that loss of melanization, and perhaps sclerotization, may precede reduction of this section (Ulrich, in. litt.). The development of cross-vein m-m is also subject to individual variation in this species.
