Indocryphalus suongmu sp. n. was described from northern Vietnam. A cladistic analysis of all nine species based on 22 morphological characters found I. suongmu and I. machili Wood as sister species. Species relationships, character evolution and patterns of ecology/geography were discussed in context of the cladogram. A modification of Beaver’s (2000) key was presented to accommodate I. suongmu and I. machili. A new country record was reported for I. sordidus (Blandford).

Numbers above branches indicate unambiguous character state changes (character number: state number to state number), see text for character and state details. Numbers below branches are bootstrap values. H, horizontal; V, vertical; in reference to the orientation of the mycangium.
