laeta ( Nixon, 1954; Pachysema )

Group: 2d.

Literature: Nixon 1954 -265; Griffiths II-565, III-802 (K III-895); Tobias (128, 179); Gaal (1996); Papp (2007b, p. 31).

Hosts: Hypothesis— Parasitoid of leaf-mining Agromyzidae though precise associations unclear. Evidence— Records from Phytoliriomyza melampyga on Impatiens ( Balsaminaceae ), Griffiths (5), NMS (5); Phytomyza spp. on Ranunculaceae, Griffiths (19); Agromyza spiraeoidearum ( = arunci ) and A. idaeiana ( = spiraeae ) on Roseaceae, Griffiths (2). Comment —Further research is needed to understand this restricted but disjoint host range.

DNA Barcode: cluster of specimens in BOLD but no BIN assigned.

Similar species: D. groschkeana .

laevipectus Thomson, 1895

Synonymy: nox (Morley, 1924, Rhizarcha ).

Group: 1a. Literature: Nixon 1937 -67; Nixon (K 1948-219); Griffiths III-839 (K III-894); Tobias (48, 66). Hosts: Hypothesis— Parasitoid of Phytomyza spp. , chiefly attacking species feeding on Ranunculaceae & Apiaceae , though also P. glechomae on Glechoma ( Lamiaceae ). Evidence— Griffiths (170); NMS (659). DNA Barcode: Yes; large number of specimens in BOLD with a single individual assigned to a sister BIN but morphologically indistinguishable from laevipectus ; several DNA sequences in GENBANK mislabeled D. sibirica . Notes: Very common species. Haviland (1922) provides a detailed description of the larval development of a species she calls Dacnusa areolaris but which from the host association is almost certainly this species.

liopleuris Thomson, 1895 Group: 2c. Literature: Griffiths V-25 (III-826), not keyed; Tobias (111, 195). Hosts: Hypothesis— Parasitoid of Campanulomyza gyrans mining Campanula persicifolia ( Campanulaceae ) and Liriomyza scorzonerae mining Scorzonera humilis ( Asteraceae ). Evidence— Griffiths (7). Comment— Disjunct host range needs further research. Similar species D. veronicae .

lissos ( Nixon, 1954; Pachysema ) Group: 2d. Literature: Nixon 1954 -268; Griffiths III-813 (K III-898) [VII-352]; Tobias (146, 197). Hosts: Hypothesis— Phytomyza spp. mining Ranunculaceae . Evidence— Griffiths (12). Comment— Recorded hosts: P. abdominalis on Hepatica spp. , P. aconitophila on Aconitum , P. anemonantheae on Anemone sylvestris .

lithospermi Griffiths, 1967 Group: 2d. Literature: Griffiths III-810 (K III-899); Tobias (148). Hosts: Hypothesis— Phytomyza lithospermi feeding on Lithospernum officinale ( Boraginaceae ). Evidence— Griffiths (1).

longicauda Thomson, 1895 Group 1b. Literature: Nixon 1954 -211; Griffiths I-890. Notes: Nixon synonymised with D. stramineipes . Griffiths examined two Thomson specimens under this name and concluded they “represent two different species in the Dacnusa stramineipes group” which he did not revise. Status currently unclear.

longiradialis Nixon, 1937 Group: 1a. Literature: Nixon 1937 -68; Nixon 1948 -220; Griffiths (K III-894); Tobias (41, 72). Hosts: Hypothesis— Parasitoid of Phytomyza milii feeding on Poaceae . Evidence— NMS (28). DNA Barcode: Yes. Similar species: D. longithorax .

longithorax ( Tobias, 1962) Group: 1a. Literature: Tobias (1962); Tobias (73). Similar species: D. longiradialis .

lonicerella Griffiths, 1967 Group: 2d. Literature: Griffiths III-819 (K III-896); Tobias (122). Hosts: Hypothesis—Parasitoid of Aulagromyza cornigera (= Paraphytomyza lonicerae ) on Lonicera xylosteum ( Caprifoliaceae ). Evidence—Griffiths (1).

lugens (Haliday, 1839; Alysia ) Group: 1c. Literature: Nixon 1937 -69; Nixon 1948 -224; Griffiths (K III-892); Tobias (36, 54). Similar species: D. arctica .
