Miktoniscus medcofi Lemos de Castro, 1953: 529 , fig. I; Lemos de Castro, 1971: 10, fig. 3; Souza-Kury, 1998: 668; Araujo & Bueno, 1998: 186; Leistikow & Wägele, 1999: 7; Schmalfuss, 2003: 166.

Material examined

Brazil, Pará: three ♂ (one in micropreparations) , four ♀, two specimens without pleon, Canaã dos Carajás, SB karst area, 6°17′S, 49°59′W, undated, leg. R . Bessi ( UFRGS 5374 ) .

Remarks

At present Miktoniscus includes 15 species distribut- ed in the USA, Mexico, Brazil, and western Europe ( Schmalfuss, 2003). Miktoniscus medcofi ( Van Name, 1940) was described from specimens collected in glasshouses in Illinois, USA. Four species ( Trichoniscus veracrucensis Mulaik, 1960 ; Miktoniscus humus Mulaik & Mulaik, 1942 ; Miktoniscus alabamensis Muchmore, 1964 , and Miktoniscus ohioensis Muchmore, 1964 ) are considered junior synonyms of M. medcofi (see Schultz, 1976). This species has been recorded from several localities in southern and central USA, Vera Cruz in Mexico, and in the Brazilian states of Amapá, Pará, Rio de Janeiro, São Paulo, and Rio Grande do Sul, where it is most probably introduced. The species is fully re-illustrated herein ( Figs 1–4 ) with the material from Canaã dos Carajás to allow for future diagnosis.
