Roubikia latebrosa Klimov and OConnor 2007

Roubikia latebrosa Klimov et al., 2007: 118, Figs 1,5,6; Klimov et al., 2007a: 1371 (included in morphological phylogenetic analysis); Klimov & OConnor, 2008: 103 (included in key)

Material (show database records). Holotype. HDN - PERU: Loreto, Iquitos, ex Tetrapedia sp., (1st metasomal tergite), 13.ii.1989, D.W. Davis, USNM, BMOC 96-0510-213; deposited in USNM. Paratypes. 5 HDNs - same data as holotype; 7+4 HDNs - 20 km from Ucayali on Rio Calleria, Colonia Calleria, ex Tetrapedia sp., (metasomal acarinarium on 1st metasomal tergite + lateral mesosoma), 10-30.ix.1961, B. Malkin, FMNH, BMOC 03-1008-052. Paratypes in USNM, FMNH, UMMZ.

Description. Deutonymph. Gnathosomal setae present, well-developed. Dorsal extensions of apodemes I-II not completely surrounding setae scx. Setae si about twice as long as se or longer, usually as long or longer than distance from lateral edge of prodorsal shield to base of si + distance between si. Genual setae mG I slightly pectinate. Setae mG II nearly as long as leg II (with claw). Other characters as in Roubikia panamensis (Baker, Roubik & Delfinado-Baker 1987).
Diagnosis. This species can be distinguished from other species of Roubikia by the relatively long internal scapular setae si that are twice as long as se or longer (si less than twice as long as se in all other species of Roubikia known to us).
Variation. One supracoxal seta scx is enlarged (30), solenidion-like (length of the other scx is 7) (BMOC 96-0510-213#6).
Hosts. Tetrapedia sp.
Distribution (show map). Peru.
Etymology. Latebrosus (= here hidden) is a Latin adjective.
Note. Phoretic in the acarinarium situated on the 1st metasomal tergite.
