Lanthanomyia pardos Heydon , n. sp.

( Figs 19 , 25, 26, 27 )

Diagnosis. Females of L. pardos are medium to large-sized (maximum body length just over 3 mm) with the microsetae of the body dark and reclinate, but more or less straight. The dorsum of the mesosoma is uniformly brownish yellow but the propodeum and pleural regions are black. The antenna has the scape cylindrical and extending to the level of the median ocellus, A1 twice as long as wide, and the flagellum weakly clavate with the basal funicular segments elongate and the terminal segments quadrate or slightly transverse. The occipital foramen is well below the vertex. The wing membrane is clear. The gaster is more than twice as long as wide and as long as the combined length of the head and mesosoma.

Description. Holotype, female (MNNC). Color. Head with face and gena white; frons brownish yellow; vertex brownish yellow with diffuse darker patches laterally above scrobe, with darkly pigmented ring connecting ocelli with occiput ( Fig. 25 ) occiput dark brown. Pronotum with collar and spot on posteriolateral corner black; brown laterally, white dorsally; mesoscutum and scutellum brownish yellow; dorsellum white; pleural region and propodeum brownish black except area below wing base and down mesepimeron paler. Gaster dark brown with T6–7 and ventral parts yellowish brown. Antenna pale brown except scape and F1 darker. Legs pale yellow except for base of hind coxa and median spot on dorsum of hind femur darker. Wing with membrane hyaline; submarginal vein and stigma reddish brown, remainder of venation yellowish white. Body setae dark.

Sculpture. Metapleuron smooth; propodeum with irregular sculpture medially and reticulate laterally with reticulations greatly elongated.

Structure. Body length 3.2 mm. Head pentagonal in anterior view ( Fig. 26 ), width 1.3× height (52:40), 2.1× length (52:25); eye height 1.2× length (24:20), 1.8× malar distance (24:13), length 4.0 × temple length (20:5); ratio of MOD, OOL, POL, LOL as 3.5:5.0:13.0:7.0; occipital foramen in normal place so pronotum touches occiput on vertical surface. Antenna with scape extending to level of median ocellus, cylindrical with anterior edge rounded; length of pedicel plus flagellum 1.2× head width; relative lengths of scape, pedicel, A1–2, F1–6, club as 27.0:12.0:4.0:5.5:5.0:5.5:5.0:4.5:4.5:4.0:9.0; relative widths of F1, F6, club as 2.5:5.0:5.0; both anelli 2x as long as wide; F1–2 appearing elongate, F2–4 quadrate, F5–6 transverse. Mesosomal length 1.8× width (86:49); propodeum with sharp, straight median carina and low broad tubercles laterally just inside of postspiracular sulcus. Fore wing length 2.5× width (200:80); relative lengths of submarginal, marginal, postmarginal, and stigmal veins as 77:29:50:19. Gaster length 2.3× width (102:44), 1.0× combined length of head and mesosoma (102:101).

Variation. The paratype female is similar except it is darker in coloration with the vertex mostly dark and with the spots dorsolateral of the scrobes large and distinct, the ocellar region is dark brown and most of mesoscutum and scutellum is orangey brown. It is also smaller with a body length of only 2.8 mm.

Type material. Holotype ( MNNC) and paratype female ( UCDC) were collected in CHILE, Región X, Oncol Park, Quitaqui Way (39˚42’S 73˚18.6’W), 520m, 10.I.2007 by E. Arias and the Berkeley crew. They were fogging a Saxagotheae conspicua tree.

Etymology. The species name comes from the Greek word pardos , meaning leopard or panther, and continues the cat theme in this genus. It should be considered a noun in apposition.
