Libellago lineata

Habitus: The exuvia studied resembles closely the specimen depicted from Malaysia (Fig. 19 a). It is impossible to determine the coloration due to adhering detritus but living specimens from Malaysia (Figs 19 b, c) are both very similar to L. hyalina in the form of the head, antennae and caudal spikes but the legs are obviously shorter, the hind femur reaching the middle of S 6 (mid S 7 in L. hyalina), and the abdomen slightly more elongate. The caudal spikes are about 55 % of the body length, significantly shorter than in L. hyalina, but of nearly identical form. The coloration is unusually dark, especially on the mid and hind tibiae, but the tip of the pedicel is unmarked, as in L. hyalina.

Mouthparts: prementum (Fig. 9 e) similar to that of L. hyalina (Fig. 9 d) but distinctly shorter and broader; Lateral margins with slightly more extensive recurved spines interspersed with short setae; Anterior median lobe less produced and median cleft shorter terminating in a small, open nearly circular aperture, as in H. biseriata and also illustrated for L. lineata by Fraser (1919). Labial palps very similar to L. hyalina but inner (lower) branch of palpal lobe not strongly hooked. Maxillae and mandibles not noticeably different from L. hyalina.
