- Key to species and species groups of Hecaloidella (excluding H. brunifasciata) 1 Vertex with distinct longitudinal or oblique striations at least to anterior transverse sulcus; pronotum with distinct transverse striations; forewing with outer subapical cell tapered basally (Figs. 2B, 3D); aedeagus disassociated from connective ( H. nitida species group )....................................................................................... 2 - Vertex and pronotum smooth or with indistinct striations; forewing with outer subapical cell tapered posteriorly (Fig. 1I); aedeagus associated or disassociated from connective.......................................................... 6 2 Vertex without brown anterior spots................................................................. H. nitida - Vertex with pair of brown anterior spots................................................................... 3 3 Vertex spots large (Fig. 1A); rest of vertex uniformly yellow (Fig. 2A)................................. H. bimaculata - Vertex spots small (Fig. 1B) to moderately large (Fig. 1E); rest of vertex orange anteriorly........................... 4 4 Vertex spots extending to fore margin; forewing dark with inner margin of clavus variably yellowish (Figs. 1E–F); aedeagus with a basal ventral spine-like process (Fig. 4L)..................................................... H. pacifica - Vertex spots not extending to fore margin; forewing not as above; aedeagus with basal ventral process not spine-like...... 5 5 Connective caudal extension with a long basal ventral process (Fig. 4C)............................... H. caudospina - Connective caudal extension without a basal ventral process (Fig. 4H)................................. H. nudapenis 6 Pronotum, mesoscutum and scutellum laterally with one small brown spot (Figs. 1N–S); aedeagus disassociated from connective ( H. quadripicta species group )...................................................................... 12 - Pronotum and mesonotum not marked as above; aedeagus associated with connective ( H. borneoensis species group )..... 7 7 Vertex with a brownish spot each side of midline nearly coalescing basally (Fig. 1M); connective stem not extended caudally, with a pair of apical spines (Fig. 6Q); aedeagus with a long ventral process from preatrium (Fig. 6S)............ H. spinosa - Vertex uniformly brown or with a brick shaped brownish band each side of midline and a smaller brown mark next to each eye (Figs 1H–L); connective stem extended caudally, aedeagus without a ventral process from preatrium................... 8 8 Aedeagus with either a single very small subapical process dorsally or two pair of apical processes.................... 9 - Aedeagus without processes............................................................................ 10 9 Aedeagus with a single small subapical process (Fig. 6F)............................................
