Posted - 18/03/2017 : 09:28:48Dialeges pauper Pascoe, 1857 has been described from "Borneo" & "Malacca"
Dialeges pauperoides Holzschuh, 1984 has been described from "Malaysia, Kg. Sahom ; Taiping ; Cameron Highlands"
Both species have the same range, which is not helpful.
In this post, Francesco tell us, by reading Holzschuh description, that the differences between the 2 species are really unclear.
- For some people, it is a matter of body size, but ... - For some people, it is a matter of hairs on antennomera, but... - For some people, it is a matter of pronotum sculpture, but...
Who is able to confirm or affirm something for all subsequent post ?
Who is able to prove that 2 species exist, rather than one ?

Posted - 04/07/2017 : 07:40:03 Small update: I have just received a female of D. pauperoides (antennae as long as body, large postmedian black spot) from Sabah measuring 23 mm.
Thus, the updated sizes are:
pauperoides Body size: 23-44
pauper Body size: 14-37

Posted - 18/03/2017 : 13:07:16 Thank you , If it is ok for females (antennae shorter vs as long as), I do not see any strong difference in males for the shape of pronotun, neither for elytral pubescence.

Posted - 18/03/2017 : 11:56:55 In my opinion, this Beckey's photo is very helpful:
pauperoides (left) and pauper (right)
pauperoides shows more rounded pronotum and more uniform elytral pubescence. Females show antennae shorter than body Body size: 28-44
pauper shows more squared pronotum and elytral pubescence making two sharp "squares" linked by a longitudinal dark strip Females show antennae as long as body Body size: 14-37
