Key to species of Trichoceridae View in CoL View at ENA known from Korea

1. Relatively small in size, wing 4–6 mm long, D-cell pentagonal, first tarsal segment very short, only about 1/10 of the second segment............................................ Subfamily Paracladurinae , Paracladura rasnitsyni Krzemińska View in CoL

- Larger in size, wings mostly 7–9 mm long; D-cell more triangular, first tarsal segment long, up to twice as long as the second segment........................................................................ Subfamily Trichocerinae , 2

2. Wing patterned, dark areas over the base of vein Rs, cross-veins r-m, r-r, around D-cell, over the radial vein area and medial veins, at the end of A2 ( Fig. 1–6 View FIGURES 1 – 9 )......................................... T. (S.) maculipennis punctipennis Brunetti

- Wing unpatterned ( Fig. 7 View FIGURES 1 – 9 ), or at most with a spot over cross-vein r-m ............................................ 3

3. Gonostylus with one or more conspicuous processes at mid-length.............................................. 4

- Gonostylus without processes at mid-length; at most with an inconspicuous basal tubercle........................... 6

4. Gonostylus with one triangular, acute process at mid-length; apex of gonostylus hooked ( Fig. 20 View FIGURES 20 – 30. 20 )..................................................................................................... T. (T.) sakaguchii Alexander

- Gonostylus with two or three processes....................................................................5

5. Gonostylus with one long, straight process at base and one smaller process closer to apex ( Fig. 24 View FIGURES 20 – 30. 20 )... T. (T.) sibirica Edwards View in CoL

- Gonostylus with one long, slightly bent process at base and two processes at apex, forming a “V” shape ( Fig. 25 View FIGURES 20 – 30. 20 ). Distal wing cells with macrotrichia............................................................ T. (T.) mirabilis Alexander View in CoL

6. Pleuron with setae on both anepimeron and metepisternum ( Fig. 23 View FIGURES 20 – 30. 20 ).................. T. (S.) sparsa Starý & Martinovský View in CoL

- Pleuron bare or rarely with one or two setae either on anepimeron or metepisternum.................................7

7. Ventrobasal lobes of gonocoxites not fused, with a clear gap (i.e. gonocoxal bridge incomplete, Figs. 22, 23 View FIGURES 20 – 30. 20 )............. 8

- Ventrobasal lobes of gonocoxites fused, forming a complete bridge ( Figs. 17–21 View FIGURES 10 – 19. 10 View FIGURES 20 – 30. 20 )...................................9

8. Ventrobasal lobes of gonocoxites rather narrow, forming a high arc ( Fig. 22 View FIGURES 20 – 30. 20 ). Usually a clear spot is visible on r-m, tarsal claw only slightly shorter than the last tarsal segment...................................... T. (S.) regelationis (Linnaeus) View in CoL

- Ventrobasal lobes wide, they form a rather low arc ( Fig.26–27 View FIGURES 20 – 30. 20 ). Wings clear, tarsal claw equals half of the last tarsal segment ( Fig. 29 View FIGURES 20 – 30. 20 )........................................................................... T. (S.) latipons View in CoL sp. nov.

9. Gonostylus longer than gonocoxite, slightly bent at mid-length, slightly sinuous, without basal tubercle ( Fig. 19 View FIGURES 10 – 19. 10 ); one of the

largest species, wing length 8–9 mm ...................................................... T. (T.) major Edwards View in CoL - Gonostylus approximately equal in length to gonocoxite, with tooth-like or smaller triangular tubercle at base.......... 10

10. Basal tubercle of gonostylus thin and acute, tooth-like ( Fig. 18 View FIGURES 10 – 19. 10 ). Sternite IX with an outgrowth at median, directed toward the bridge (not clearly visible in all specimens)............................................. T. (T.) hiemalis (De Geer) View in CoL

- Basal tubercle triangular and blunt ( Fig. 17 View FIGURES 10 – 19. 10 ). Sternite IX lacking median outgrowth.................................................................... T. (T.) tuberculifera Alexander View in CoL ( T. latilobata View in CoL ( Fig. 21 View FIGURES 20 – 30. 20 ) should key out here as well).
