Lohmannia jornoti Mahunka, 1985

Mahunka 1985a: 124, f. 11-15; Balogh and Balogh 1987: 334, pl. 8 A; 1988: 53, pl. 33 F; 2002a: 65; 2002b: pl. 116:12; Schatz 1993: 70, figs. 1-6.

Dimensions: adult 800 – 840 x 380 – 460 µm, deutonymph 540 x 335 µm.

Sensillus with 12 branches in adult, 10 branches in deutonymph, posterior exobothridial setae wide, size 45 x 30 µm in adult, 35 x 15 µm in deutonymph. Medial notogastral setae phylliform with serrated margins, narrow. Posterior medial genital setae setiform and ciliate.

Remarks: A direct comparison with specimens from Galapagos was possible. The specimens from Bermuda correspond to those and the original description ( Mahunka 1985a) in most respects and are considered conspecific. The body size of the specimens from Bermuda is in the range of the population from Guadeloupe (length 794 – 826 µm) but considerably smaller than the population from the Galapagos Islands (930 – 1020 µm, Schatz 1993). Also the deutonymph is smaller than in specimens from Galapagos (680 – 725 x 355 – 380 µm, Schatz 1993). The species is very similar to L. banksi Norton et al., 1978 . It differs mainly in having smaller posterior exobothridial setae, smaller and differently shaped notogastral setae, and setiform posterior medial genital setae.

Records from Bermuda: BE 124: 1 adult. BE 310: 1 adult, 1 deutonymph .

General distribution: Antilles, Guadeloupe: un- der shrubs near the sea ( Mahunka 1985a); Ecuador, Galapagos Islands: under Sesuvium shrubs in the littoral zone on Santa Cruz Island, in leaf litter of a dense elfin-forest on VolcAEn Alcedo (Isabela Island), in fern litter and moss near a fumarole on Fernandina Island ( Schatz 1993); Central America: Belize Light House Reef: Half Moon Cay, in leaf litter ( Schatz 1994b: 276; Schatz 2006); Cuba Ciudad de La Habana, Santiago de las Vegas, sugar cane ( Saccharum spp. ), leaf litter and soil ( Prieto and Calderón 1992); first record for Bermuda.
