Description
TABLE 1. Most useful diagnostic characters for separating the four species described in detail—*found in all or most other known species in the genus.
| character | Heliocypha biseriata | Aristocypha fenestrella | Sundacypha petiolata | Llibellago hyalina |
|---|---|---|---|---|
| subocular spines on genae | relatively short, mainly blunt and numerous, anterior two spines somewhat longer and more acute | two long anterior acute spines with remainder sparse and mostly acute In ventral view | strong acute anterior spine with sparse, upturned spines seemingly blunt in ventral view | weakly acute cluster of small short spines, without longer anterior spine |
| Prementum | elongate, flared distally with convex margins; median cleft open | elongate, flared distally with convex margins; median cleft mostly fused | strongly elongate, flared distally with straight margins; median cleft mostly fused | *weakly elongate, *margins with recurved spines in distal half; median cleft fused |
| Antenna | ca 1.50 times head width; * tip of pedicel dark; * numerous short recurved setae on scape | ca 1.45 times head width; * tip of pedicel dark; *setae on scape long, straight | ca 1.63 times head width: tip of pedicel dark | *ca 1.11 times head width; * tip of pedicel pale, unmarked |
| Female genital apophyses | inner apophyses long, reaching up beyond tip of epiproct; tip of outer apophysis a thin spine deflected downward away from inner | Unknown | inner apophyses very long, reaching up beyond tip of epiproct; tip of outer apophysis broadly tapered to a point directly backward away from inner | inner apophyses shorter, reaching tip of epiproct; tip of outer apophysis broadly tapered upwards in line with inner, almost reaching tip of latter |
| Caudal spikes | Long (ca 55% body length) and broad: * tapered smoothly to point from about midway | Medium length (ca 40% body length); * relatively broad until just before apex, where abruptly tapered to point | Very long (ca 65% body length), thin and tapered gradually to a point | Very long (ca 65% body length); *slightly swollen basally then very thin and tapered gradually to a point |
