Diagnosis.

Paridris dnophos may be strikingly similar to Paridris nayakorum in coloration and shape of the body. Females may easily be separated by having only 1 basiconic sensillum on A8, versus 2 in Paridris nayakorum ; by the absence of striation on T1; and the linear form of the posterior notaulus. The presence of an externally visible metascutellum serves well to separate Paridris dnophos in most cases, but this character should not be used alone given that a few specimens of have a large horn on T1 and reduced metascutellum. Etymology. The Greek epithet “dnophos” means “darkness” and is given to this species for the color of its body. The name is treated as a noun in apposition.

Comments.

Morphological variation within Paridris dnophos occurs primarily in color and density of setation and punctation on the head and mesosoma. The antennae, legs, T1, and anterior T2 range from black to yellow; the head, mesosoma and remainder of the metasoma vary from black to brown. The setation of the head and dorsal mesosoma varies from white to golden yellow and may be extremely sparse to dense. The density of punctation and setation of the lateral pronotum are similarly variable.
