214. Dactylobiotus ambiguus ( Murray, 1907c) sensu lato [F]

Macrobiotus ambiguus Murr. 1907 ( Rahm 1931, 1932) Macrobiotus ambiguous - type ( Montoya et al. 2010) Terra typica: Hungary (Europe)

Argentina:

• 37°20′S, 59°08′W; 200 m asl: Buenos Aires Province, lagoon in Tandil (Lago del Fuerte), sample of plant ( Potamogeton ferrugineus Hagström ). Rossi & Claps (1991)

Brazil:

• 23°51′S, 46°29′W; 750 m asl: São Paulo State, between São Paulo and Santos, in the primary forest, in bromeliads. Rahm (1931, 1932)

Venezuela:

• 08°45′N, 70°49′W; 4,150 m asl: Region Los Andes, Mérida, Mucuñuque Mt., surface samples from peat bog. Montoya et al. (2010)

Record numbers: Argentina: 1, Brazil: 1, Venezuela: 1; total: 3.

Remarks: With a largely Palaearctic or high latitude Holarctic distribution ( McInnes 1994a) the limited South American reports appear anomalous. Dactylobiotus species require careful analysis of both adults and eggs for confident identification (e.g. Kaczmarek et al. 2012b). We suggest these South American reports require further investigation.
