Species Guides
1- Chilacis typhae(bulrush bug)
Chilacis is a of true bugs in the Artheneidae, established by Fieber in 1864. The genus contains at least two described , including the extant Chilacis typhae (bulrush bug) and the fossil species †Chilacis univestis. Members of this genus are associated with bulrush (Typha) and possess a distinctive symbiotic relationship with an obligate intracellular bacterium housed in a specialized structure termed a "mycetocytic belt."

More Details
Symbiotic Bacterium
Chilacis typhae possesses an obligate intracellular bacterium in the epithelium, located at the end of the first section of the midgut. This structure consists of circularly arranged, strongly enlarged midgut epithelial forming a "mycetocytic belt," which may represent an evolutionarily intermediate stage of symbiotic structures in stink bugs. The bacterium belongs to Gammaproteobacteria and is phylogenetically related to a secondary endosymbiont of Cimex lectularius and free-living plant such as Pectobacterium and Dickeya. The is rod-shaped and transmitted vertically via detection at the poles of developing .
Fossil Record
The includes one fossil , †Chilacis univestis Statz & Wagner, 1950.
