Key to adult males of the genus Neozavrelia View in CoL View at ENA
1. Antenna with 10 flagellomeres. Anal point covered with microtrichia and short colorless spines. The lateral lobes at the anterior margin of tergite IX are well developed. Digitus well developed, extends beyond the edge of the superior volsella or forms a separate lobe......................................................................................... 2
- Antenna with 13 flagellomeres. Anal point with dark spines of various lengths. The lateral lobes on the anterior margin of tergite IX are absent. Digitus only partially extends beyond the edge of the superior appendage or is located under it......... 8
2. Digitus protrudes beyond the edge of the superior volsella and is located on a separate lobe. Anal point narrow and expanded medially ( Figs 5–6 View FIGURES 1–8 ). Inferior volsella foot-shaped laterally ( Figs 7–8 View FIGURES 1–8 ).................. N. fengchengensis Wang & Wang View in CoL
- Digitus is developed to varying degrees, but does not form a separate lobe. The anal process, if narrow, is not expanded medially. Inferior volsella laterally of a different shape............................................................ 3
3. Total body color light yellow. The last segment of the antenna short (<800 μm) and apically widened ( Fig. 124 View FIGURES 123–126 ). Sensilla chaetica on ta 1 P 2 absent............................................................... N. yakuefea (Sasa & Suzuki) View in CoL
- Total body color yellowish brown or dark brown. Apex of last segment of antenna without widening. Sensilla chaetica on ta 1 P 2 usually present........................................................................................ 4
4. The anal point broadly triangular, rounded apically. The superior volsella is elongated-oval, expanded medially and covers only the base of the digitus ( Figs 89–91 View FIGURES 88–92 , 96–99 View FIGURES 93–99 ). Sensilla chaetica on ta 1 P 2 absent. The apex of the antenna apex slightly widened ( Fig. 94 View FIGURES 93–99 ). AR 0.56–0.61............................................................. N. paramushirica View in CoL sp. nov.
- The anal point parallel-sided. The superior volsella oval-shaped, half covers the digitus. Basitarsus of mid leg with 2–5 sensilla chaetica. The apex of the antenna normal................................................................... 5
5. Inferior volsella reaches 2/3 of the length of the gonostylus. Anterior margin of tergite IX straight. Superior volsella without microtrichia ( Figs 60 View FIGURES 60–64 , 67–70 View FIGURES 65–70 )........................................................... N. nadezhdae View in CoL sp. nov.
- Inferior volsella reaches 1/2 of the length of the gonostylus. Anterior margin of tergite IX triangular. Superior volsella usually with microtrichia...................................................................................... 6
6. Mid tibia with 1 spur ( Fig. 45 View FIGURES 43–48 ). Antenna length <900 μm. Maxillar palp length <500 μm, second palpomere swollen ( Fig. 43 View FIGURES 43–48 ). R with 11–15, R 4+5 with 2 setae, M 3+4 without setae......................................... N. kuzmichikha sp. nov.
- Mid tibia with 2 spurs. Antenna length>900 μm. Maxillar palp length>500 μm, second palpomere narmal. R with 17–29, R 4+5 with 11–25, M 3+4 with 3–16 setae......................................................................... 7
7. Wing length 2.6–2.7 mm. Antenna length about 1200 μm. R 1 with 0–4 setae. Frontal tubercles absent always. Gonostylus 133–150 μm long. Superior volsella densely covered with microtrichia ( Figs. 53–59 View FIGURES 53–55 View FIGURES 56–59 )................ N. minuta (Linevich) View in CoL
- Wing length 1.8–2.4 mm. Antenna length less than 1200 μm. Frontal tubercles are about 2 mm in diameter or absent. R 1 with 8–14 setae. Gonostylus 102–129 µm ( Figs 16–18 View FIGURES 9–22 ). Superior volsella with rare microtrichia or without them ( Figs 13–15 View FIGURES 9–22 )....................................................................................... N. kedrovaya View in CoL sp. nov.
8. Ventral seta on the superior volsella absent. Superior volsella broad, elongated oval-shaped ( Figs 102–103 View FIGURES 100–103 , 134–135 View FIGURES 132–135 )...... 9
- Ventral seta on the superior volsella present. Superior volsella narrow, elongated oval-shaped ( Figs 80–81 View FIGURES 77–81 , 112–113 View FIGURES 110–113 )...... 10
9. Anal point short and broad rounded apically, dorsally with 14–16 dark strong spinulae located in a semicircle in the apical part ( Figs 132–135 View FIGURES 132–135 ). Maxillary palp normal ( Fig. 136 View FIGURES 136–140 )............................................... N. zarya View in CoL sp. nov.
- Anal point sclerotized along the edges, truncated apically, medially with 5 dark spinulae ( Figs 108–109 View FIGURES 104–109 ). The second member of the maxillary palp is longer than the third and fourth ( Fig. 104 View FIGURES 104–109 )................................ N. samarga View in CoL sp. nov.
