Key to species of Agrionympha based on adult maculation (Figs. 2 A–I)

Although a highly conservative genus, the species can be confidently diagnosed from FW maculation and certain other colour differences. In the key, the nomenclature for the 4 band marks follows that outlined in the generic diagnosis.

NOTE: males are not yet known for vari, jansella, and pseudovari; while sexual dimorphism in wing pattern is minimal or non-existent in the great majority of micropterigids, it does occur in a few taxa, and its possible occurrence here must always be kept in mind.

1 Claval mark confluent with median band (e.g. Fig. 2 A or F)................................................... 2 Claval mark discrete or absent (e.g. Fig. 2 B or G)............................................................ 3 2(1) Median band complete, forming with the claval mark an arrowhead-like figure (Fig. 2 F)............... sagittella sp. nov. Median band interrupted in middle: anterior part forming a broad L-shape with the claval mark; posterior part appearing dis-

tally displaced, forming a discrete spot on dorsum (Fig. 2 A).............................................. capensis 3(1) Median band complete from costa to dorsum (e.g. Fig. 2 C), postmedian band either complete (e.g. Fig. 2 B) or incomplete (e.g. Fig. 2 C............................................................................................. 4 Median band represented by only a spot on dorsum, postmedian band complete from costa to termen (Fig. 2 E).................................................................................................. kroonella sp. nov. 4(3) Claval mark absent (Fig. 2 G)............................................................... jansella sp. nov. Claval mark distinct (e.g. Fig. 2 D)........................................................................ 5 5(4) Apical band a distinctive, usually dark-edged spot or short transverse band (e.g. Fig. 2 H)........................... 6 Apical band exceedingly reduced, represented by a few light scales, or completely absent (Fig. 2 D)... fuscoapicella sp. nov. 6(5) Postmedian band interrupted i.e. not a continuous band from costa to termen (e.g. Fig. 2 C)........................... 7 Postmedian band complete from costa to termen (Fig. 2 B).......................................... karoo sp. nov. 7(6) Postmedian band interrupted in middle, but present as distinctive spots on both costa and termen (e.g. Fig. 2 C).......... 8 Postmedian band present only as a narrow band from costa to the middle of the wing (Fig. 2 H)............... pseliacma 7(6) All silvery bands distinctly edged with black scales; costal part of postmedian band almost circular (Fig. 2 C).................................................................................................. pseudovari sp. nov. Silvery bands not edged with black scales; costal part of postmedian band nearly 3 times longer than wide (Fig. 2 I)..... vari Key to species of Agrionympha based on male postabdomen & genitalia (Figs. 7–10) Note: males unknown for A. vari, A. jansella and A. pseudovari .

1 Specialized hair-sensilla present on membranous dorsum between tergum VIII and tergum X lobes; valvae length:width ratio 4.0 or less.......................................................................................... 3 Hair-sensilla absent in said area; valvae length:width ratio 4.0–5.7............................................... 2

2(1) Hair-sensilla present on anterior border of tergum VIII; valvae elongate, length:width ratio greater than 5 (Fig. 10 C).................................................................................................... sagittella Tergum VIII devoid of hair-sensilla; length:width ratio of valvae 4.0 (Fig. 7 B)............................... capensis

3(1) With less than 45 hair-sensilla; median plate narrow, tapered anteriorly, at least 3x longer than wide; phallus without conspicuous internal sclerotised body........................................................................... 4 With about 80 hair-sensilla; median plate broad and rectangular, approx. 2x longer than wide; ductus ejaculatorius thickening just inside gonopore conspicuous, roughly textured and somewhat sclerotised (Fig. 9 E)....................... kroonella

4.(3) Gonopore small, less than half the width of the Phallus between lappets; ‘neck’ of phallus constricted in dorsal view..... 5 Gonopore large, well over half width of aedeagus between lappets; ‘neck’ of phallus not constricted.. undescribed ‘species 1’ NOTE: while pseliacma will run to this couplet, the unique slide preparation made by Janse does not allow observation of the phallus character used here; the species has more than 30 hair-sensilla like both ‘species 1’ and fuscoapicella .

5(4) More than 30 hair-sensilla on dorsum IX; gonopore plain, without a dorsal prominence (Fig. 8 C)............ fuscoapicella Fewer than 20 hair-sensilla on dorsum IX; gonopore with its proximal margin raised on a prominence (Fig. 9 C)....... karoo
