Key to the species of
Hirsutopes
currently known from the Andaman Islands
The distribution of the three known species of
Hirsutopes
is shown in
Fig. 14
. All of them are endemic to the Andaman Islands.
H. andamanensis
and
H. megaoculatus
occur on the main archipelago from North Andaman Island (historical data) down to South Andaman Island (recent data), and
H. pajnii
sp. n.
seems to be restricted to
Havelock Island. The three species can be separated as follows:
1 Pronotum irregularly and coarsely punctuate, elytral intervals strongly vaulted, intervals 1–4 glabrous and generally deprived of green scales, these mainly scattered along striae and on lateral intervals, so that elytra appear dark (or brownish, depending on the body colour) and greenish striped (
Fig. 12
). Penis broad, apex broadly triangular with sharp tip (
Figs 6–7
) .. ....................................................

– Pronotum with regular and fine punctuation, elytral intervals weakly vaulted, intervals 1–4 not glabrous, green scales arranged other than above: either homogeneously green or pattern less contrasting and not in stripes ............................................. 2
2 Vestiture homogeneous, consisting of green-bluish scales (
Fig. 13
). Penis narrow, apex acutely angular and regularly pointed to tip (
Figs 8–9
) ........

Pajni, 1990
– Vestiture greenish with dark spots on first five and last two intervals, intervals 6and 7and most of suture entirely set with green-bluish scales (
