Treatment

Aphelinus paluscolus sp. nov.

Description: Holotype ♀. Length of body 1.29 mm, excluding ovipositor 1.2 mm.

Head completely dark brown; antenna yellow. Thorax dark brown with metallic reflection. Tegula dark but not as dark as thorax. Gaster basal 1/3 yellow or light brown and rest brown. Forewings hyaline. Legs yellow, only hind coxae slightly infuscated.

Mesoscutum with short silver setae and a pair of long setae at the apex, scutellum with 2 pairs of long setae. Forewings with delta region proximal to linea calva with 1–2 complete and 1–2 incomplete lines of setae.

Head slightly shiny. Ocelli forming an angle of about 100°. Antenna with apex of clava more or less pointed ( Figure 5 View Figures 1–6 ). Eye reaching occipital margin; upper temple rounded in facial view. Eye margins on the face curved. Scrobes moderately deep, U-shaped. Antennal torulus separated from mouth margin by about its own length.

Relative measurements on slides: HW 33, FV 11, POL 6, AOL 4, DPO 2, DAO 2, OOL 1.5, OCL 1, EL 15, MSL 10.

Paratypes ♀ (length including ovipositor 1.24–1.36 mm, without ovipositor 1.14–1.29 mm). Forewing venation as in Figure 6 View Figures 1–6 .

Material examined: Holotype: NORWAY, AKERSHUS [AK], Oslo: ØstensjØvannet, Northern shore [N59.89732°, E10.83020° ± 10 m; 99 m a.s.l.], 1♀ 1–30 Sept. 1996, Malaise trap, leg. Morten Falck & Lars Ove Hansen GoogleMaps . Paratypes: 2♀♀ [locality as holotype]; 1♀ NORWAY, AKERSHUS [AK] , SØRUM: SØrlilØkka, Dammyra [N60.00523°, E11.17698° ± 50 m; 193 m a.s.l.], 28 August 2011, leg. Ove SØrlibråten GoogleMaps .

Holotype and paratypes deposited at the Natural History Museum, University of Oslo, Norway; designated to the NHM, Oslo, Norway. One paratype deposited at the collection of Agricultural University of Georgia, Tbilisi, Georgia.

Biology: Unknown, but both localities are boggy or swampy sites with reeds ( Pragmites australis ), particularly the ØstensjØvannet locality where the Malaise trap was situated in a huge population of reeds. It is thus thought that the host species is associated with reeds.

Distribution: Norway.

Etymology: From New Latin palus, meaning marsh, swamp, bog, and colus from Latin meaning inhabiting, dwelling.

Comments: The new species is similar to A. certus , but differs by the following morphological characters: legs yellow, only hind coxa slightly infuscated ( certus : only femura and fore tibia yellow); clava 2.2× as long as broad ( certus : 2.5×); F 3 transverse ( certus : longer than broad); F 1 – F 3 together not longer than pedicel ( certus : F 1 – F 3 together longer than pedicel); costal cell almost as long as marginal vein ( certus : costal cell clearly much longer than marginal vein).
