Malay Hesperiidae for ID

[DJHiker]

Some confusing Hesperiidae, all from Malaysia, observed Feb.-March 2019.
I think 1, 2 and maybe 3 could be Potanthus.
4 and 5 Telicota?

1. Kuala Selangor
25840

2. Kuala Selangor
2584125842

3. Raub, Pahang
25845

4. Kuala Tahan
25843

5. Cameron Highlands
25844

Would very much appreciate your opinion.

#1. Potanthus sp. Uncertain . Since FW spot 8 is reduced in size could be P. juno.

2; Potanthus juno: FW spot 8 absent (ie only 2 subapical spots) ; Abdominal end black ;often FW spot 5 is smaller than spot 4 but not here.

A female P. juno.Note FW subapical 8 absent (may be vestigial) spot 5 smaller than spot 4;

3. Ampittia dioscorides.

4. Female Telicota colon ;Note spot 4 detached from spot 3 ; spot 4 & 5 not fully overlapping; HW no spot 7 (both sides) All Potanthus should have spot 7.

Potanthus are very difficult without both upperside & undersides.
There are far more species in Vietnam.

1. More orange; HW veins not darkened. Probably P. ganda.

2. Yellower; HW veins not darkened; abdominal end dark. Probaly P. mingo

3 , 4, & 5. Taractrocera archias ;antennal club without apiculus (tip) HW with hockeystick mark.

6 HW veins not dark ;FW band without overlap to subapical spots; HW band's outer spot just shifted out a little.
Probably P. nesta.
