Fig. 1

Microphorus albopilosus: Becker 1910: 644 . Type locality: Corsica (Chvála 1986: 444, figs 9, 28–33 ( Microphor )).

Description:

Fully re-described by Chvála (1986: 444). The description of the terminalia of both sexes is updated as follows:

Male terminalia ( Figs 1A–C ). Left epandrial lamella quadrate with short knob-like process posterior to surstylus; right lamella subrectangular. Left surstylus slender, finger-like, bearing some setulae, with hooked tip and expansion near mid-length; right surstylus broadly expanded and rounded with short pointed knob-like process. Hypandrium fused basally to each epandrial lamella; prolonged from broad base, gradually tapered to broad rounded apex, bearing pair of apical setae, less than one-third length of hypandrium; apex one-third of basal width of hypandrium. Phallus sickle-shaped with slender digitiform apex. Left postgonite digitiform, folded medially beyond epandrial lobe; apex rounded, right postgonite long, flat, closely appressed to inner face of epandrial lamella, tapered to point. Cercus short, bilobed, bearing several long setae.

Female terminalia ( Fig. 1D ). Tergite 10 divided medially, bearing 2 pairs of stout setae (acanthophorites); outer pair of setae more slender and pointed, inner setae peg-like with rounded apex. Cercus shorter than width of tergite 10, rounded apically, bearing several slender subapical setae.

Material examined: TURKEY: Antalya Prov.: 15ơ 2^Phaselis , 10 km S Kemer, 0 m, 27.iv.2000, B. Merz & Senay leg.; 9ơ 12^Side (= Selimye), 2.v.2000, 0 m, B. Merz & Senay ( ZFMK) .

Distribution and seasonal occurrence: This species is known from Spain, Corsica, Sicily, Greece and Turkey, from April to June.

Remarks: This species has been collected on a sandy boggy shoreline (in the same place as Epithalassius Mik , Dolichopodidae s.str.) at the end of June ( Corsica). The material examined in this study from Turkey represents a new country record. These specimens were collected on sand dunes covered partly with vegetation, some 100 m behind the beach (Merz, pers. comm. 2006).

Chvála (1986) indicated that the syntypic series of this species is deposited in Becker’s Collection in Berlin, but a lectotype has not been designed .
