Key to larvae of Crassabwa View in CoL View at ENA /g1

1. Larva of Baetidae View in CoL with the following combination of characters: Claw shallowly bent, with 2 rows of denticles ( Figs 19 View FIGURES 17–27 , 70 View FIGURES 69–77 ). Labial palp «chelate», i.e. with inner-apical projection of 2nd segment ( Figs 5 View FIGURES 5–9 , 69 View FIGURES 69–77 ). Hind protoptera present, i.e. winged stages have hind wings....................................................................................... 2

- Some of these characters absent: either claw sharply bent and/or with 1 row of denticles, or labial palp non-chelate (i.e., without inner-apical projection of 2nd segment), or hind protoptera absent or vestigial (i.e. winged stages have no hind wings)............................................................................................ other Baetidae View in CoL .

2. Outer side of each femur, besides a row of stout setae, with 2 stout subapical setae brought together ( Kluge 2016: Figs 21, 25, 26 View FIGURES 17–27 ). This combination of characters is present in the following taxa: (1) New World genus Paracloeodes Day 1955 View in CoL , belonging to Baetovectata (in larva patella-tibial suture on fore leg present, in adult fore wing with 2 marginal intercalaries per space); (2) Old World genus Cheleocloeon Wuillot & Gillies 1993a View in CoL , belonging to Anteropatellata-non-Baetovectata (in larva patella-tibial suture on fore leg present, hind protoptera only in male, in adult fore wing with 1 marginal intercalary per space); (3) Afrotropical genus Bugilliesia Lugo-Ortiz & McCafferty 1996c View in CoL , belonging to Protopatellata (in larva patella-tibial suture on fore leg absent, in adult fore wing with 1 marginal intercalary per space); and (3) poorly known species Delouardus djabala Lugo-Ortiz & McCafferty 1999 View in CoL in Madagascar. - Outer side of each femur, besides a row of stout spatulate setae, with 1 stout spatulate subapical seta ( Fig. 18 View FIGURES 17–27 ). Members of Protopatellata: in larva patella-tibial suture on fore leg absent ( Figs 13–15 View FIGURES 10–16 ), in adult fore wing with 1 marginal intercalary per space ( Fig. 50 View FIGURES 47–51 ). Claw with two most distal denticles of each row enlarged ( Figs 19 View FIGURES 17–27 , 70 View FIGURES 69–77 ) ( Crassabwa View in CoL /g1)................. 3

3. Tergalius I in proximal half with anal margin concave and armed by slender rib, without portion bent ventrally ( Figs 20 View FIGURES 17–27 , 72 View FIGURES 69–77 ). Abdominal terga II–VI either without denticles, or with irregular denticles alternating with scales ( Fig. 37 View FIGURES 34–40 ) ( Susua View in CoL )........ 4

- Tergalius I in proximal half with anal margin convex, not bordered by rib; in last larval instar its anal portion usually bent ventrally ( Kluge et al. 2017: Figs 23 View FIGURES 17–27 , 84 View FIGURES 78–86 ). Abdominal terga I–X with regular row of pointed denticles on posterior margin ( Kluge et al. 2017: Fig. 20 View FIGURES 17–27 ) ( Crassabwa View in CoL )......................................................................... 5

4. Tergalius I as long as tergalius II ( Figs 20–21 View FIGURES 17–27 ). Mesonotum with sharply projected median ridge ( Fig. 41 View FIGURES 41–46 ). Pronotum with 1 pair of tufts of spatulate setae, mesonotum with 2 or more pairs of tufts of spatulate setae ( Figs 28–31 View FIGURES 28–33 ). Legs relatively slender ( Figs 13–15 View FIGURES 10–16 ).............................................................................. Susua sigiensis

- Tergalius I much longer than tergalius II ( Figs 72–73 View FIGURES 69–77 ). Mesonotum without prominent median ridge ( Fig. 78 View FIGURES 78–86 ). Pronotum and mesonotum without tufts of spatulate setae ( Fig. 87 View FIGURES 87–90 ). Legs relatively thick ( Figs 91–93 View FIGURES 91–96 )............... Susua niandanensis View in CoL

5. In last instar larva, cuticle of fore protopteron with dark lines corresponding to convex longitudinal veins only ( Kluge et al. 2017: Fig. 4 View FIGURES 1–4 ). Mola of left mandible with even row of denticles ( Kluge et al. 2017: Fig. 8 View FIGURES 5–9 )............... Crassabwa flava View in CoL

- In last instar larva, cuticle of fore protopteron with dark lines corresponding to convex, concave and cross veins ( Kluge et al. 2017: Fig. 62 View FIGURES 62–68 ). Mola of left mandible with tubercles bearing denticles ( Kluge et al. 2017: Fig. 81 View FIGURES 78–86 )..................... 3

6. Claw relatively short, with portion from distal denticle to apex shorter than portion from distal denticle to base ( Kluge et al. 2017: Figs 66 View FIGURES 62–68 , 95 View FIGURES 91–96 )..................................................................... Crassabwa ludmilae

- Claw relatively long, with portion from distal denticle to apex longer than portion from distal denticle to base ( Kluge et al. 2017: Fig. 126)........................................................................ Crassabwa ameliae
