KEY TO THE INSULAMON View in CoL SPECIES
Proper identification without comparative material should be based on adult males.
1. Carapace not broader than 1.29 times length, and G1 with long distal part (tip) of terminal segment as long as or longer than dilated proximal base ( Figs. 3D View Fig , 7F View Fig ) .................................... 2
– Carapace at least, but usually more than 1.29 times as broad as long, and G1 with short distal part (tip) of terminal segment always shorter than dilated proximal base ( Figs. 5 View Fig F–K, 9F, 11F) ....................................................................................... 3
2. Male telson less than 1.2 times as broad as long ( Fig. 2C View Fig ). Tip of G1 sharply tapered ( Fig. 3 View Fig C–E). (Calamian Islands) ........ ................................................................................. I. unicorn View in CoL
– Male telson more than 1.2 times as broad as long ( Fig. 6C View Fig ). Tip of G1 not sharply tapered, rather clubbed or hooked ( Fig. 7 View Fig D–H). (Palawan) .................................................. I. magnum
3. Male sixth abdominal somite not broader than 1.9 times length, and tip of G1 distinctly hooked, perpendicular to the longitudinal axis ( Fig. 9 View Fig D–H). (Palawan) .................... I. johannchristiani View in CoL
– Male sixth abdominal somite at least, but usually broader than 1.9 times length; tip of G1 more or less straight, not hooked, pointing somewhat in the direction of the G1 longitudinal axis, not perpendicular ( Figs. 4 View Fig A–C, F–K, 11D–H). (Palawan) .. 4
4. Distal portion of G1 terminal segment corkscrew-like, curly at its base; proximal portion of terminal segment slender, not inflated subproximally and appearing evenly tapered ( Fig. 11 View Fig D–H). Terminal segment of mandibular palp most narrow medially, not evenly tapering. (Palawan) ........... I. porculum View in CoL
– Distal portion of G1 terminal segment not corkscrew-like at its base, only slightly twisted or bent at its base and proximal portion of terminal segment at least slightly, usually distinctly inflated subproximally and not evenly tapered ( Fig. 4 View Fig A–C, F–K). Terminal segment of mandibular palp evenly tapering towards apex. (Palawan) ................................ I. palawanense View in CoL
