Key to genera of Luciolinae View in CoL View at ENA using males
Keys to genera of the Luciolinae , beginning with Ballantyne & McLean (1970), addressed increasing numbers of genera as the taxonomy expanded, but have never included either Luciola cruciata or L. owadai (see review in Ballantyne et al. 2019). It is possible to distinguish Nipponoluciola gen. nov. from other Luciolinae genera by the following, without the need for a complicated generic key.
Of those Luciolinae genera with LL visible at the sides of the ML, only two genera have a narrow base to the elytral epipleuron such that the elytral humerus is visible from beneath if the specimens are held horizontally ( Fig. 3 View Fig ), Missimia and Nipponoluciola gen. nov. Missimia ( Figs 4E‒H View Fig ; Table 1 View Table 1 ) is a rare genus known from four specimens collected in the New Guinea highlands, distinguished most obviously from Nipponoluciola by its pale brown dorsal colouration, its distribution in the New Guinea highlands, the acute posterolateral corners of the pronotum in males, the inflexible nature of the clypeolabral suture, the absence of a median notch in the aedeagal basal piece, and the presence of a well-defined and depressed area on the outer margins of the lateral lobes of the aedeagus bearing setae ( Ballantyne & Lambkin 2009: figs 21–22, 27, 29–30, 32‒34, 246‒254). The two species of Nipponoluciola have black elytra, are known only from Japan including the Ryukyu Islands, the posterolateral corners of the pronotum are rounded, the clypeolabral suture is flexible, most aedeagi examined have a median notch in the basal piece, and there is no depressed setae bearing area on the outer margins of the lateral lobes of the aedeagus ( Figs 1 View Fig , 2G‒H View Fig , 5 View Fig ).
List of genera of Luciolinae having aquatic larvae
Fu et al. (2010) noted that verified records of aquatic firefly larvae are rare, and given that original descriptions rarely give any indication of any larval associations or accurate habitat data, that adults are often described without knowledge of the larval types. It is thus possible that the incidence of aquatic Luciolinae will ultimately be shown to be wider than the range we address here.
Fu et al. (2012b) defined aquatic larvae as possessing either gills along the sides of the abdomen*, or having spiracles only at the end of the abdomen # (metapneustic). Those marked with superscript J are from Japan.
The following list includes genera and species for which confirmation of aquatic larval status exists.
A. hydrophila ( Jeng et al., 2003)
A. lateralis (Motschulsky, 1860) J
A. leii (Fu & Ballantyne, 2006)
A. wuhana Fu & Ballantyne, 2010
S. aquatilis (Thancharoen, 2007)

Key to aquatic larvae in the Luciolinae
Fu et al. (2012b) keyed the genera listed above from larvae. They addressed five species of Aquatica ( Fu et al. 2012b: figs 1‒24, 61–62, 67–68, 73‒80, 91), two species of Sclerotia which were still attributed to Luciola ( Fu et al. 2012b: figs 31‒42, 70, 83‒86), and two species of Nipponoluciola gen. nov. which were also still attributed to Luciola ( Fu et al. 2012b: figs 25‒30, 69, 81–82). See also Fu et al. (2010: figs 25–26, 30–31, 44‒49) for Aquatica larvae.
