Key to genera of Borralinae

1 Carapace without obvious patterning (with uniform light grey to fawn hair cover in life), profile arched, usually highest midcaput; eyes relatively small; MA unipartite; epigynum often with a large scape projecting over the epigastric groove (sometimes reduced or absent) (Gray & Smith, 2002, figs 1, 4) ............................................................................ Therlinya View in CoL

—— Carapace patterned with a pair of longitudinal grey-brown stripes, profile in males typically slopes up to fovea, weakly arched to flattish in female; eyes relatively larger; MA bi- or unipartite; epigynum without scape, fossa divided or undivided (the “striped group” genera) .................................................................................................................. 2

2 Males .............................................................................................................................................. 3

—— Females .......................................................................................................................................... 9

3 RVTA with a long, thick stalk and “crochet-hook” like head; epigynal fossa undivided .................................................................................................................... 4

—— RVTA with stalk short or absent; epigynal fossa divided or undivided ........................................................................................................................................... 5

4 RTA large, deeply bifurcate (Gray & Smith, 2004, fig. 11a) ............................................... Pillara View in CoL

—— RTA large, not bifurcate (Gray & Smith, 2004, fig. 4a) ..................................................... Borrala View in CoL

5 Conductor with a ventral process (VCP). MA unipartite ( Figs 16a View Fig , 17a View Fig ) ............................................................................................................................. Elleguna View in CoL

—— Conductor without a ventral process, MA bi- or unipartite ........................................................... 6

6 Conductor with a smoothly curved anterior margin, lacking processes ............................................................................................................................................. 7

—— Conductor with anterior margin modified by flange-like processes ............................................... 8

7 Lateral MA process weakly sclerotized and entire (not bifurcate); RDTA long, keel-like (“keel” shorter and notched in A. hayllari View in CoL ) ( Figs 18a,b View Fig – 21a,b View Fig ) ................................................................................................................ Asmea View in CoL

—— Lateral MA process strongly sclerotized and bifurcate spiniform; RDTA not keel-like ( Figs 9a,b View Fig – 12a,b View Fig ) ............................................................................ Jamberoo View in CoL

8 TL area indistinct; MA lateral process large, sclerotized and spiniform, with a flap-like basal spine ( Figs 13a,b View Fig , 14a,b View Fig ) ....................................................... Karriella View in CoL

—— TL large; MA lateral process not as above ( Figs 6a,b View Fig , 7a,b View Fig ) ........................................... Couranga View in CoL

9 Epigynum with a large, median, knob-like process placed anteriorly; fossa absent. (Gray & Smith, 2004, fig. 13c–e) ............................................. Pillara View in CoL (part)

—— Epigynum not as above; knob or knobs, if present, smaller and posteriorly placed; fossa present ........................................................................................................ 10

10 Fossa not divided (an indistinct median line may be present) ..................................................... 11

—— Fossa divided by a distinct median septum ................................................................................. 15

11 Fossa a small, in-sloped pit sometimes partially hooded by the anterior fossa margin; spermathecae posterior to fossa (overlap- ping in P. karuah View in CoL ) (Gray & Smith, 2004, figs 10c, 11c, 12c) ..................................... Pillara View in CoL (part)

—— Fossa larger, not as above; spermathecae posterior to or level with fossa ............................................................................................................................................. 12

12 Fossa elongate, open posteriorly; a pair of rounded knobs on the posterolateral epigynal plate (knobs may be damaged) (Figs 13d–f, 14d) ........................................................................................................................ Karriella View in CoL

—— Fossa margin entire, knob-like processes absent ......................................................................... 13

13 Fossa large, floor with conjoined socket-like recesses posteriorly; lateral fossa margins flanged inwards over copulatory openings
