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