Remarks

Systematics: http://zoobank.org/2FCC872E-35E0-4BCF-88F1-FC47316422B5 Adult females of L. sealakeensis are most superficially similar to those of L. maculosus; both species occur under bark, have an invaginated anus, and relatively robust, subconical marginal setae. Adult females of L. sealakeensis can be readily distinguished from those of L. maculosus by (i) the lack of dorsal macrotubular ducts (two size-classes present in L. maculosus); (ii) dorsal microtubular ducts with sclerotic surrounds (these are unique among Sphaerococcopsis and Lachnodius spp.); (iii) capitate dorsal setae (lanceolate in L. maculosus); and (iv) the ventral surface of abdomen with macrotubular ducts with the shaft constricted distally (not constricted distally in L. maculosus). Capitate dorsal setae like those of L. sealakeensis are also present on adult female of Sphaerococcopsis platynotum Beardsley and S. umbilicus Beardsley. These differ mfro L.sealakeensisin having (i) 6-segmented antennae (7-segmented in L. sealakeensis); (ii) hind legs much larger than fore and mid legs (all legs subequal in L. sealakeensis); and (iii) venter much larger than dorsum (venter and dorsum subequal in L. sealakeensis). (Hardy, et al., 2019)

Structure: Adult female body outline oval; length 0.84–1.45 mm, greatest width 0.70−1.28 mm. Eyes not apparent. Antennae seven-segmented; length. Dorsum with dermal orifice of each microtubular duct surrounded by sclerosis; marginal fringe of truncate setae; dorsal setae capitate; anal ring invaginated. (Hardy, et al., 2019)
