description: Lenkothrips kaminskii sp. n.
(Figs 13–19)
Female. Body dark brown, head and pronotum darker (Fig. 13); femora uniformly brown, tibiae brown medially; all tarsi yellow; antennal segments largely brown, I & II darker; basal half of III and basal third of IV yellow (Fig. 14); fore wing brown with a pale sub-basal area (Fig. 16).
Head about 1.3 times wider than long, with no long setae, ocellar setae minute, pair III inside ocellar triangle, just in front of posterior ocelli (Fig. 15), ocellar area weakly reticulate; three pairs of postocular setae arising near inner margin of eyes and three additional pairs close to outer margin. Antennal segment III longer than segment IV, both with a long and continuous sensorial area extending laterally to the basal fifth. Pronotum with strong sculpture; about 30 discal setae and 7–8 pairs of short posteromarginal setae (Fig. 15). Mesonotum closely striate, distance between striae less than 4 microns medially (often narrower than discal setal pore); metanotum with concentric lines bearing many microtrichia (Fig. 17). Fore wing with two complete rows of strong, brown setae; clavus with 7–8 setae and one discal setae.
Abdominal tergites I–VIII with independent fringe of posteromarginal microtrichia, well developed laterally on I–V but bearing only few teeth medially; lateral thirds covered with dense rows of fine microtrichia (Fig. 18). Sternites with 6 pairs of posteromarginal setae arising well in front of posterior margin.
Measurements (holotype female in microns). Body length about 1300 (–1165). Head, length 117; width 160. Pronotum, length 160; width 230. Hind tibia length 195; width 33; hind tarsus length 57; width 17, Fore wing length 745. Antennal segments I–IX length (width), 25 (30), 35 (25), 82 (22), 70 (22), 20 (16), 22 (12), 15 (10), 17 (8), 20 (5), respectively.
Male. Smaller and paler than female; sternites IV–VIII each one with a relatively small oval pore plate at antecostal ridge (Fig. 19).
Measurements (paratype male in microns). Body length about 915. Pronotum, length 127; width 182.
Material examined.
Holotype female (UFRGS), Brazil: Rio de Janeiro: Paraty (23º20’36”S, 44º42’47”W), 29.xii.2010, from Stigmaphyllon? auriculatum flowers (Malpighiaceae), A. Cavalleri.
Paratypes: 1 female, 1 male collected with holotype.
Comments. This species shares many characters with L. guaraniticus described above. In both species, the pronotum is sculptured with distinct lines and the antennal morphology is similar with long sensoria on segments III & IV. However, in L. kaminskii, the basal half of antennal segment IV is yellow, not brown, and segments VII–IX are distinctly longer than in L. guaraniticus. In contrast to the other Lenkothrips species, the mesonotum is closely striate and the male pore plates are relatively small and oval. This species was found co-existing with Scutothrips nudus (Moulton) in the yellow flowers of climbing Stigmaphyllon shrubs only a few meters from the coast.
