Differential diagnosis

Orphnus parvus is similar to O. bicolor in having the pronotum without a tubercle on base medially and endophallus with a few groups of spinules. It differs from the latter in having the parameres in dorsal view without notches basad of lateral teeth ( Fig. 5G View Fig ), shorter parameres (about 0.5 length of phallobase [ Fig. 5E View Fig ] as opposed to 0.7 length of phallobase in O. bicolor [ Fig. 4E View Fig ]), and abdominal sternite 8 medially as long as sternites 4–7 combined (as opposed to sternite 8 medially distinctly longer than sternites 4–7 combined in O. bicolor ).
