Revision of Paranastatus Masi (Eupelmidae, Eupelminae) with descriptions of four new species.

Paranastatus Masi, 1917 (Eupelmidae, Eupelminae) was originally described based on two species from Seychelles: Paranastatus egregius and Paranastatus violaceus. Eady (1956) subsequently described Paranastatus nigriscutellatus and Paranastatus verticalis from Fiji. Here, four new species of Paranastatus are described: Paranastatus bellus Scallion, sp. n. and Paranastatus pilosus Scallion, sp. n. from Indonesia, and Paranastatus halko Scallion, sp. n. and Paranastatus parkeri Scallion, sp. n. from Fiji. A key to all Paranastatus species based on females is included and lectotypes are designated for Paranastatus egregius and Paranastatus violaceus. Finally, previously unobserved colour variation from newly collected material of Paranastatus verticalis, distribution patterns of species, and possibilities for future research are discussed.
