Delia sanctijacobi (Bigot, 1885:296; Anthomyia ). Lectotype male, UMO. Type-locality: “Chile”.

Diagnosis.

Male. First tarsomere of midleg with a brush of long setulae (longer than tibia width) on its dorsal surface. Row of 32-45 pv setae on hind tibia longer than tibia width. Sternite 5 processes each with 2-3 truncate spinules on inner apical corner. Cercus approximately 3 times as long as wide with 6 long apical setae. D. sanctijacobi genitalia is quite similar to D. platura , except postgonite slightly longer than in D. platura (similar to postgonite length) and distally narrowed in lateral view. Surstylus 1/3 more enlarged than D. platura .

Redescription.

Measurements: Male. Body length 4.5-5.0 mm; wing length 4.7-5.3 mm (Fig. 3B ). - Head: Eye sparsely and shortly setulose; frontal vitta dark brown; eyes separated by less than width of anterior ocellus (Fig. 3A ); frontal setae 5-8 pairs; short interfrontal setae usually present; fronto-orbital plate and parafacial brownish or yellowish-orange, with gray pruinosity; antenna dark-brown, postpedicel approximately 2.0 times longer than wide; arista short pubescent; gena with gray pruinosity, genal height approximately 3 times the pedicel length (Fig. 3B ); anterior margin of gena with 2-4 upcurved subvibrissal setae; palpus dark-brown. - Thorax: Light-brown with gray pruinosity; scutum distinct with 3 black vittae visible at acrostichals region and among dorsocentral and intra-alars (Fig. 3C ); acrostichal setae 3+6-9, dorsocentral setae 2+3, intra-alar setae 1+2, prealar seta about half length of posterior notopleural seta; scutellum light-brown, ventral margins with white hairs apically, basal scutellar setae and apical scutellar setae developed; notopleuron with two same length setae and without covered setulae; prosternum, anepimeron, meron and katepimeron bare; katepisternal setae 1+2. - Legs: Entirely dark-brown; fore tibia with 1 medial pv, preapical d with half-length of first tarsomere, and apical seta on v; mid femur with a row of setae on ad and av, a row of long (longer than femur width) pv in basal half; mid tibia with 1 pd, 1-2 pv and 1 submedian ad, long (longer than tibia width) apical setae on a, d, pv, v, first tarsomere of midleg with a brush of long setulae (longer than tibia width) on its dorsal surface; hind femur with a complete row on ad becoming long apically, a basal half row on pv, an apical half row on av and d; hind tibia with 3-5 av, 7-11 ad, 4 pd, becoming longer apically, 32-45 pv with slightly bent tips in largely duplicated rows, a preapical d, apical setae on av. Claws black and pulvillus white. - Wing: Veins bare, except costal; costal with all spinules short (pair before distal break twice longer), ventrally bare; dm-m slightly sinuate; calypteres yellow, marginal hairs long and light yellow, lower calypter developed, but smaller than upper; halter yellow. - Abdomen: Slender, with gray pruinosity and a dark stripe dorsally, dense and long setulose, marginal setae longer (approximately 1/3 of abdomen length) (Fig. 3C ); sternite 1 with long dense setulae (longer than sternite length); sternite 4 with a pair of long setae (longer than sternite length); sternite 5 processes projecting, with outer lateral setae becoming longer distally, each with 2-3 truncate spinules on inner apical corner (Fig. 4A ). - Terminalia: pregonite with 2 setae; postgonite with 1 seta; cercus approximately 3 times as long as wide, elongate-ovoid (broadest on distal half) with 6 long setae distally and 4 long lateral setae on each side; surstyli slender and almost twice longer than cercus, phallapodeme straight; epiphallus short, similar to postgonite length; distiphallus long, three times longer than pregonite, bifurcate distally (Figs 4C ; 5A, B ).

Similar to male, except: Frons approximately 1/3 of head width (Fig. 3D ); frontal vitta approximately 5 times as wide as fronto-orbital plate; a pair of interfrontal setae; region among interfrontal setae and lunula yellowish-orange; 5 pairs of frontal setae; outer vertical seta long and divergent; inner vertical seta long and convergent; ocelar, outer vertical seta and inner vertical seta with similar length; fronto-orbital plate and parafacial with brownish-gray pruinosity; body with brownish-gray pruinosity (Fig. 3E, F ); fore tibia with 1 medial ad; mid tibia with 2 median ad, pd and pv; pre-apical setae on ad, av, pd and pv; hind tibia with 2-3 av and 5-7 ad; pv bare; abdomen not slender (Fig. 3E, F ). - Terminalia: tergites 6-8 reduced to pairs of lateral plates; spiracles 6 and 7 situated on posterior half of segment 6; sternite 6 and 7 long and narrow, bearing a pair of long and few shorter setae posteriorly; sternite 8 represented by a pair of small plates, each bearing 5 setae; epiproct trapezoid, with a long distal pair of setulae; hypoproct triangular covered by setulae; cerci setulose, twice longer than epiproct; three round spermathecae (Figs 4E, F ; 5C-F ).

Remarks.

The female of D. sanctijacobi is morphologically indistinguishable from D. platura . Their identity must be confirmed by DNA barcoding. The ultrastructural morphology of male and female genitalia revealed a high similarity between the species. No difference was observed in the SEM images of D. sanctijacobi presented here (Fig. 3 ) and the images of D. platura presented by Wang et al. (2014), except that the D. sanctijacobi epiphallus is twice as long as that of D. platura (Fig. 3B ).

Life history.

According to the label information, some specimens were found in soy, onion and broccoli. Here, we report some larvae feeding on the roots of broccoli ( Brassica oleracea L. var. italica ( Brassicaceae ).

Distribution.

Alaska (Cold Bay and Unalakleet), Argentina (Jujuy, Tucumán, Córdoba, Santa Fe, Mendoza, Neuquén and Río Negro), Brazil ( Paraná, Santa Catarina, Rio Grande do Sul), Chile (Juan Fernández Islands, Los Lagos, Valparaíso and Araucanía), Peru (Cuzco) and Uruguay.
