Species: Indosialis bannaensis Liu, Yang & Hayashi, 2006
Phylum: Arthropoda
Class: Insecta
  Order: Megaloptera
   Family: Sialidae
    Genus: Indosialis

 Female: The adult female has striking yellow-orange body coloration with smoky-black wings. Terminalia are most readily distinguished by the heavily sclerotized, diamond-shaped 8th gonapophysis with an emarginated posterior edge and the 8th gonocoxite divided into a pair of partially sclerotized subtriangular lobes. The body is strongly setose (Bowles and Contrearas-ramos, 2016).
 Larva: One large and one small subapical mandibular teeth, yellow-orange body coloration with weak maculation, and the configuration of the fused mentum and submentum that bears a small oval sclerite on the posterior margin appear to be strong diagnostic characteristics for this genus (Bowles and Contrearas-ramos, 2016).
