Two new genera of Zodariidae, belonging to the Zodariinae and strongly related to Mallinella Strand, are reported from evergreen forests in Thailand and Malaysia. Euryeidon gen. n. is represented by six species, all of which are new: E. monticola sp. n. (the type species; ♂ ♀), E. musicum sp. n. (♂ ♀), E. anthonyi sp. n. (♂ ♀), E. sonthichaiae sp. n. (♂), E. consideration sp. n. (♀) and E. schwendingeri sp. n. (♀). The genus is characterized by its strongly reticulate carapace and widely spaced eyes. Heradion gen. n. is represented by five new species, all known from both sexes, which can be clustered in two species groups on the base of somatic characters. The first group, found in Thailand, consists of Heradion naiadis sp. n. (the type species) and H. peteri sp. n. The second group is restricted to Malaysia and consists of three smaller, long-legged species: H. pernix sp. n., H. damrongi sp. n. and H. luctator sp. n. Heradion is characterized by: carapace smooth, domed; chilum drawn out into a point, pointing forward; sternum with anterior concavity accommodating labium; sclerotized field in front of the spinnerets with rows of hairs; femora inflated dorsally near proximal dorsal spine; coxae I and IV elongated. Keys to the genera of Zodariinae in Southeast Asia and to the species of Euryeidon and Heradion are provided.
