( Fig. 3)

Empis macropalpa Egger, 1860: 344 (original description).

Diagnosis. Greyish species with brownish legs, labrum about as long as head height, presutural supraalar seta fine, M 2 abbreviated; male with scape and palpus with numerous rather long setae; female with mid femur with a few short posteroventral pennate setae apically, hind femur with ventral pennation on apical half.

Lectotype designation. The original description is based on both sexes from Sicily but the number of specimens examined was not given by Egger (1860). In the NMW collection, five males and three females are

present and all labelled in the same way: “Mann, 1858, Sicilia; Empis, Alte Sammlung ”. Specimens are conspecific and correspond to the original description and thus here considered syntypes . A male specimen is herewith designated as lectotype of the species and labelled accordingly to fix and stabilize the current concept of the name. The remaining seven specimens become paralectotypes .

Re-description. Male. Head. Occiput dusty greyish, covered with fine, rather long black setae. Ocellar triangle with pair of fine setae. Scape dark brown with numerous long setae, pedicel dark brown, postpedicel black. Labrum dark brown, slightly longer than head height; labium blackish; palpus blackish, long, projected, with numerous distinct setae.

Thorax. Dusty greyish. Antepronotum with a few black setae. Antepronotal lobes with 1 rather fine, long black basal bristle, many other finer, short brownish to pale yellow anteriors. Proepisternum, prosternum with fan of pale yellow setae. Scutum with 3 blackish stripes on acrostichals and dorsocentrals; acrostichals quadrito biserial, fine. Dorsocentrals quadri- to biserial, fine, except for 3-4 strong, long prescutellars. Other strong, long setae as follows: 1 presutural, 1 postsutural supraalars; 3 notopleurals. Laterotergite with fan of long pale yellow setae. Anterior, posterior spiracles yellowish.

Wing. Length about 6.7 mm. Feebly tinted of brown. M 2 abbreviated. Halter yellow.

Legs. Coxae greyish with many pale yellow setae. Fore femur brownish; fore tibia brownish to yellowish basally with anterodorsal row of rather strong setae about as long as tibia depth, finer posterodorsals; fore tarsus dark brown, fore tarsomeres 1–2 with strong apical setae. Mid femur brownish; mid tibia brownish to yellowish basally, with antero- and posterodorsal rows of 3-5 strong, rather long setae, antero- and posteroventral rows of strong, shorter setae on apical half; mid tarsus dark brown with tarsomeres 1–4 with 2 ventral rows of spine-like setae. Hind femur brownish to yellowish apically; hind tibia brownish to yellowish basally, with antero- and posterodorsal rows of setae as long as tibia depth; hind tarsomeres dark brown with 2 ventral spine-like setae.

Abdomen. Tergites brownish to greyish at margins, sternites greyish, covered with rather long pale yellow setae.

Hypopygium ( Fig. 3). Cercus broad, somewhat square. Epandrial lamella somewhat lengthened with many strong, long apical setae. Phallus rather simple, gently curved, not undulated.

Female. Similar to male except for following characters: scape, palpus with shorter setae. All setae on legs short; fore tibia yellowish to brownish apically; mid femur with a few posteroventral short pennate setae apically; mid tibia yellowish to brownish apically, with posteroventral group of ca. 10 very short spine-like setae; hind femur with numerous fine pale yellow ventral setae, ventral pennation on apical half. Wing clear. Abdominal setae short.

Chorotype. W-Mediterranean. Empis macropalpa is known from Sicily, but not mentioned in the on-line checklist of the Italian fauna ( Raffone 2003).
