    $\begingroup$ It is from Coleoptera (beetle), right? $\endgroup$ – Ahmed Abdullah May 15 '17 at 3:12

This appears to be some species of beetle (order Coleoptera) in the Bostrichidae family.

  • Commonly called auger beetles, false powderpost beetles, or horned powderpost beetles.

Xylopsocus capucinus

Identification to species can be difficult, but fortunately for you Sittichaya et al (2009) created an illustrated key for IDing species associated with South Asia.

Based on their key and visual characteristics of your specimen, my guess is that your specimen is Xylopsocus capucinus

enter image description here

Source: Sittichaya et al 2009 . a. lateral view; b. elytral declivity; c. intercoxal process of the 1st abdominal ventrite; d. dorsal view.

  • Description: 3-5.5 mm long; 1.4-1.7 mm wide. Shape is cylindrical and similar in general appearance to other common species of the family Bostrichidae.

  • Distribution: throughout South and Southeast Asia from India to the Indonesian archipelago.

  • Hosts: apparently polyphagous attacking almost any woody plant in suitable condition.

  • Phenology: adults emerge mainly between May and November.

Like most false powderpost beetles, the head cannot be seen from above as it is downwardly directed and hidden by the thorax:

This appears to be a Powder-Post Beetle (order Coleoptera, family Bostrichidae); a local reference is needed for further identification.

    $\begingroup$ Please provide a reference for your identification if possible. $\endgroup$ – March Ho May 17 '17 at 18:05
  • $\begingroup$ The post by @theforestecologist gives you a good example of how a well-researched answer to a species ID question looks like, even though your ID is also correct - as far as I can tell, and that is the problem: it needs some effort for me to check even though answers should be self-explanatory. Please try to give more comprehensive answers. $\endgroup$ – AlexDeLarge May 18 '17 at 7:41
