al. (1989) have mentioned following species of Aglaonema in India:
Scrutiny of names in The Plant List 2013 indicates some as synonyms.

As per efi thread :
Aglaonema….Leaf with less than 10 pairs of lateral veins
Dieffenbachia….Leaf with more than 10 pairs of lateral veins
Yes the two genera can be separated on the basis of lateral veins easily. There are other characters which can be seen when flowers appear, but as we now these foliage plants rarely come to flower in pots. If the plant is in flower these things can further help:
1. The spathe (large sheath surrounding the inflorescence) is persistent in Dieffenbachia, falls off soon in Aglaonema
2. Female flowers in Dieffenbachia have staminodes (sterile stamens), these staminodes are absent in Aglaonema
3. Stamens are united in Dieffenbachia, free in Aglaonema
4. Ovary is 2-3 celled in Dieffenbachia, 1-2 ceeled in Aglaonema.

Aglaonema (Araceae) : 1 post by 1 author.
I have updated eFI (efloraofindia) page on Aglaonema (Pl. click).
Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.
Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.
If someone can provide complete list of Indian species with source references it will be wonderful.
Any comments/ corrections are welcome.
I have added list of Indian species based on Karthikeyan et al (1989).

Pl. go through Aglaonema page (Amaryllidaceae) with images of species in efloraofindia (done by …).
If you find any mis-identification, pl. let us know.
If anybody can send images of other species of this genera (for incorporation in the website), it will be really nice. Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
