Key to males of Caloca

1 Antennal scape without a finger-like process on the anterior surface 2

– Antennal scape with a finger-like process on the anterior surface (see figs 101-b and 105-b in Mosely and Kimmins, 1953) 3

2 (1) Segment X longer than wide, gently tapering towards posterior, with anterolaterally directed spines on each lateral margin (see fig. 41-b in Mosely and Kimmins, 1953) C. saneva

– Segment X about as wide as long, with two pairs of stout spines (see fig. 463 in Neboiss, 1977) C. ascita

3 (1) Segment X lateral margins produced distally to form a triangular process at about halfway along length of lateral margin, a single pair of spines dorsally on each process (see fig. 102-b in Mosely and Kimmins, 1953) C. straminea

– Segment X lateral margins not produced distally, with more than one spine on either the dorsal or lateral surfaces 4

4 (3) Inferior appendages with large spine-like, pointed projections arising from inner surface subapically (figs 19, 20, 23, 24) 5

– Inferior appendages either without large, strong spines or with spines not subapical on segment 6

5 (4) Segment X very narrow in apical two-thirds, with dark spines restricted to basal portion (figs 23–25) C. gippslanda sp. nov.

– Segment X broad, blade-like, with dark spines dorsally along lateral margins (figs 18, 19) C. sica sp. nov.

6 (4) Inferior appendages each with at least one large spine-like projection medially (figs 7, 14) 7

– Inferior appendages without any large spine-like projections medially (figs 19, 24, 29) 8

7 (6) Inferior appendages each with one large medial spine-like projection; segment X lateral margins slightly divergent towards posterior until apical third, then angled in, with about six long setae dorsolaterally along length of segment, and a pair of strong setae on dorsal face at about mid length (figs 13–15) C. lata sp. nov.

– Inferior appendages each with one ventral and three large medial spine-like projections; segment X lateral margins slightly converging towards posterior then rounded in apical third, without spines dorsally but with a row of lateral spines in distal half (figs 6–8) C. kiandra sp. nov.

8 (6) Segment X elongate and tapered, with medial incision greater than half the length of the segment (figs 1, 33) 9

– Segment X broad, with medial incision less than half the length of the segment (fig. 28) 12

9 (8) Segment X with spines restricted to apical one-third (figs 33, 34) 0

– Segment X with at least some spines around half the length of the segment (figs 1, 2, 28) 11

10 (9) Segment X with one large, stout ventral spine and two slender lateral spines; inferior appendages broad in ventral view (figs 33, 34) C. disparala sp. nov.

– Segment X with three dorsal spines and one ventral spine; inferior appendages, in ventral view, much narrower in apical half (see fig. 105-d and e in Mosely and Kimmins, 1953) C. eba

11 (9) Segment X with one very long anterolaterally directed spine on lateral margin at about halfway along length, one very long laterally directed spine on lateral margin at about two-thirds length, one long spine on ventral margin, directed laterally from the segment but bent halfway to face posteriorly, and a small spine on the dorsal margin subapically; inferior appendages without medial projections (see fig. 106-c and d in Mosely and Kimmins, 1953 C. fallia

– Segment X with three or four spines laterally about halfway along length of segment; apices of inferior appendages broadly incised, inner process stout, pointed and shorter than outer process (figs 1–3) C. ungula sp. nov.

12 (8) Segment X with row of dark spines on lateral margins, a pair of dark spines on dorsal surface at about two-thirds length of the segment, and no spines apically; inferior appendages without medial processes (figs 28, 29) C. ada sp. nov.

– Segment X with dark spines apically; inferior appendages each with medial process (see fig. 104-c and e in Mosely and Kimmins, 1953) C. tertia
