Lampromyia bellasiciliae

sp. nov.

Lampromyia bellasiciliae sp. n.

( Figs 1–3, 5–9, 11 View FIGURES 1 – 8. 1 View FIGURES 9 – 13. 9 , 14, 17 View FIGURES 14 – 19. 14 , 20, 22–24 View FIGURES 20 – 25. 20 )

Differential diagnosis. Superficially, L. bellasiciliae sp. n. closely resembles L. pallida . Males of both species can be separated from L. iberica by the partly or entirely yellow hind coxa and metakatepisternum (black in L. iberica , Fig. 4 View FIGURES 1 – 8. 1 ) and by the dark lateral markings on tergites 2 and 3 (black transverse stripes in L. iberica ). Compared to L. pallida , L. bellasiciliae sp. n. has an evenly convex dorsal margin of the epandrium (sharply uneven in L. pallida , Figs 9–10 View FIGURES 9 – 13. 9 ), a narrowly bilobed apex of the epandrium (broadly bilobed in L. pallida , Figs 11–12 View FIGURES 9 – 13. 9 ), shorter and slimmer gonostyli and apical guides ( Figs 14–15 View FIGURES 14 – 19. 14 ) and a rectangular dorsomedial projection on the upper margin of the synsternite (rectangular projection including an apical fingerlike process in L. pallida , Figs 17–18 View FIGURES 14 – 19. 14 ). Further useful features are blackish palpi (yellowish in L. pallida ), and hind coxae lacking any conspicuous dark markings. Females of L. iberica differ from L. bellasiciliae sp. n. and L. pallida by their black hind coxae ( Fig. 4 View FIGURES 1 – 8. 1 ) and metakatepisternum and by their tiny (or absent) posterolateral glossy spots on the scutum. Unlike L. pallida , L. bellasiciliae sp. n. has blackish palpi (yellowish in L. pallida ), a predominantly black sternite 3 (anterior half yellow in L. pallida ), entirely pruinose postpronotal lobes and scutellum (upper half of postpronotal lobes and entire scutellum glossy in L. pallida , Figs 20–21 View FIGURES 20 – 25. 20 ), reduced glossy spots on scutum ( Figs 20–21 View FIGURES 20 – 25. 20 ), and lacks distinct paired median swellings on sternite 8 (present in L. pallida , Figs 23–25 View FIGURES 20 – 25. 20 ). No morphological differences are present in the genital furca of the two species ( Fig. 22 View FIGURES 20 – 25. 20 ).

Description. MALE. Head. Face projecting prominently ( Fig. 8 View FIGURES 1 – 8. 1 ), leading edge almost straight in lateral view, silver pruinose except narrowly along posteroventral margin; ground colour yellow but a dark median horizontal stripe may be present that reaches ventrally to the posterolateroventral corners; gena dark brown, small triangular, weakly silver pruinose; proboscis black, 5.6–6.8 mm, posteriorly reaching middle/end of S5 ( Fig. 2 View FIGURES 1 – 8. 1 ); palpus entirely black or somewhat yellowish beneath; frons and occiput with dark brown ground colour, thickly silvergolden pruinose, occiput with yellow-golden setulae about as long as pedicel; ocellar tubercle shining black to dark brown; antennae ( Fig. 6 View FIGURES 1 – 8. 1 ) silvery pruinose, yellow except dark brown from flagellomere 2 onwards; scape about as long as pedicel and flagellomere 1; pedicel 1/3 to 1/4 length of scape; flagellomere 1 almost straight dorsally, ventrally tapering in distal half; flagellomere 2 and 3 distinguishable, third flagellomere twice length of second but only half its width; terminal stylus with individual segments not distinguishable.

Pronotum and postpronotal lobes yellow, thinly silvery pruinose; prescutum and scutum thickly silvery pruinose, except for five small glossy spots in posterior half ( Fig. 8 View FIGURES 1 – 8. 1 ; two laterally in supra-alar area, two posterolaterally, one median just before scutellum); ground colour (mostly concealed by pruinosity) yellow with three broad longitudinal brown stripes ( Fig. 7 View FIGURES 1 – 8. 1 ), lateral ones not reaching anterior, lateral or posterior margin, median one reaching anterior margin; separated posteromedian glossy dark spot lies in continuation of median stripe and extends onto scutellum; the latter otherwise yellow, silver pruinose but shiny along posterior margin; mediotergite on upper half yellow and silvery pruinose, on lower half brown but laterally yellow and largely not pruinose especially laterally; pleura ( Fig. 8 View FIGURES 1 – 8. 1 ) mostly yellow, dark brown on greater part of anepisternum, anterodorsal region and lower half of katepisternum, lower half of meron, along anterior margin of anepimeron (especially in upper half), and with some small brown patches at other regions; pleura mostly thinly silver pruinose, glossy area mostly confined to posterior half of anepisternum and anterior half of anepimeron. Legs. Virtually entirely yellow and thinly silver pruinose; hind femur dorsally with small dark brown marking just before apex ( Figs 1–2 View FIGURES 1 – 8. 1 ), occasionally also brownish-yellow dorsally in basal 3/4; hind tibia with dark brown ring at apex; apical three tarsomeres darkened; fore tibia with one, mid and hind tibiae with two apical spurs; pulvilli minute; claws black. Wing. As in Fig. 5 View FIGURES 1 – 8. 1 ; length 7.4–8.1 mm, conspicuously shorter than body; wing membrane hyaline; veins mostly brown, darker where adjacent membrane is faintly patterned; weak pattern of dark brown areas along apices of veins R2+3, R4 and R5 (can also be along other apical veins), and at apices of cells br and bm; vein CuP present; apical flexure of R2+3 abrupt, forming almost a right angle to costal vein; halter yellowish with darkened knob. Abdomen. As in Figs 1–2 View FIGURES 1 – 8. 1 ; weakly petiolate between tergites 2–4; tergite 1 may be entirely yellow but usually with small black lateral marks that may narrowly extend onto dorsum; tergites 2–4 (sometimes also tergite 5) yellow, with black triangular lateral marks that may meet on dorsum; tergites 6–7 (sometimes also tergite 5) yellow, or dark yellowish, narrowly or broadly black along entire lateral margins; tergite 8 normally visible as narrow stripe ( Fig. 9 View FIGURES 9 – 13. 9 ); tergites 1–7 silver pruinose along anterior and posterior margins (occasionally entirely glossy); sternites 1–2 and 6–8 almost entirely black; sternites 3–4 yellow with large median black transverse stripe (occasionally almost entirely black); sternite 5 yellow with minute black central spot (occasionally almost entirely black); sternite 1 silver pruinose; sternite 2–8 glossy.

Type locality. The type locality is known as “Cave della Castellana” or “Cave di via Castellana Bandiera” ( Todaro 2004) and is situated within the city limits of Palermo, between “Via Castellana Bandiera” and “Via Cardinale Rampolla Mariano” ( Figs 26–28 View FIGURES 26 – 28 ). The site was used as a calcarenite mine until the early 20th century. Today, various adits reach 3–4 m into the rock. Within the cave, Lampromyia larvae colonise the fine sand resulting from the degradation of the calcarenite.

Etymology. The specific epithet bellasiciliae means ‘from beautiful Sicily’, and is treated as a noun in apposition.

Remarks. In the checklist of the species of the Italian fauna ( Contini et al. 1995; Stoch 2003) as well as in the FaunaEuropaea database ( Pape & Beuk 2004), L. pallida is listed as a doubtful record for Sicily. Although the primary source of this reference could not be traced, it is likely that the citation is of historic origin and refers to L. bellasiciliae sp. n.
