The hymenopteran parasitoid complex (Hymenoptera, Braconidae, Eulophidae, Pteromalidae) of the pine bark beetle Cryphalus fulvus Niisima, 1908 (Curculionidae, Scolytinae) in South Korea

The hymenopteran parasitoid complex from the families Braconidae, Eulophidae and Pteromalidae of Cryphalus fulvus Niisima, 1908 (Curculionidae, Scolytinae) developing on Pinus densiflora Siebold & Zuccarini, 1842 are studied in the Korean Peninsula. Two new chalcidoid species, Aprostocetus (Aprostocetus) tselikhae Kosheleva, sp. nov. (Eulophidae) and Allocricellius minutus Tselikh, Ku & Lee, sp. nov.

(Pteromalidae), are described and illustrated. An updated diagnosis and illustrations of the rare pteromalid monotypic genus Sigynia Hedqvist, 1974 are given; the type species Sigynia ernobii Hedqvist, 1974 is redescribed and illustrated. One species of Eulophidae, Pediobius moldavicus Bouček, 1965, and two species of Pteromalidae, Rhaphitelus maculatus Walker, 1834 and Sigynia ernobii Hedqvist, 1974, are reared from the larvae of Cryphalus fulvus for the first time.

Three pteromalid genera Allocricellius Yang, 1996, Rhaphitelus Walker, 1834 and Sigynia Hedqvist, 1974 are recorded from Korea for the first time.
