Introduction There were no reports of mites belonging to the families Erythraeidae and Trombidiidae from Samos. Mites of these families from Sporads Islands were known only from Rhodes. On this island nine species were found: Charletonia dalegori Haitlinger, C. glifadaensis Haitlinger, C. kaliksti Haitlinger, C. krendowskyi Feider, Leptus monolithosicus Haitlinger, L. andae Haitlinger, L. gennadicus Haitlinger, Erythraeus rutgeri Haitlinger and Rudaemannia rudaensis (Haitlinger) (Haitlinger, 2003a, b). Moreover, C. bucephalia Beron (mentioned as C. tamarae Haitlinger) and Phanolophus oedipodarum (Frauenfeld) (as P. nasica Andre) (Haitlinger, 1984, 1993) are known from the continental part of Greece. In this paper six new species of larval mites are described. Four species (Hauptmannia silesiacus Haitlinger, Grandjeanella multisetosa Zhang & Goldarazena, Leptus josifovi Beron and Allothrombium triticium Zhang) are reported for the first time from Greece. The species found on Samos are different from those on Rhodes and no species common for both islands were found.
Material and methods During a visit by the author to Samos between 26 May and 2 June 2003, larval erythraeid and trombidiid mites were collected from herbaceous plants, Orthoptera and Opiliones. The specimens were preserved in ethanol and then mounted in Berlese's medium. The terminology and abbreviations are adapted from Haitlinger (1999, 2003a). The holotypes are deposited at the Museum of Natural History (MNHWU). All measurements are given in micrometers (µm).

Hauptmannia silesiacus Haitlinger, 1986 Material. 2 larvae, 30.05.2003, Petalides n. Karlovassi, 1 larva, 30.05.2003, ~3 km to east from Marathokambus, Samos; all specimens were collected from herbaceous plants. Distribution: Poland, Slovakia, Slovenia, Croatia, Samos (Greece). Rare species. Specimens were collected from all countries in very small numbers (Haitlinger, 1986, 1987, 2000a, 2002, 2003c, 2004). First record from Greece.
Grandjeanella multisetosa Zhang & Goldarazena, 1996 Material. 1 larva, 30.05.2003, Petalides n. Karlovassi; 2 larvae, 31.05.2003, Kastania; 3 larvae, 29.05.2003, Pondrosso; 1 larva, 28.05.2003, 4 km to west from Pagondas; 1 larva, 30.05.2003, Agios Isidoros n. Kalithea, Samos; all specimens were collected from herbaceous plants. Distribution: Spain, Turkey, Croatia, Samos (Greece). This species may occur in the whole Mediterranean Region because recently G. multisetosa was collected from Croatia and now from Samos. Common species on Samos (Zhang & Goldarazena, 1996, Goldarazena et al., 1999, 2000, Haitlinger, 2004). First record from Greece. Leptus josifovi Beron, 1975 Material. 3 larvae, Agios Ioanni n. Votsalakia, Samos, 30.05. 2003, from undetermined Orthoptera. Larvae collected from tarsus I and basifemur I. Distribution: Bulgaria, Croatia, Samos (Greece). Not long ago this species was known only from Bulgaria. Recently it was collected many times in South Croatia, especially on various islands and sea-coast of Dalmatia. It is associated with different species of Orthoptera. Most specimens were found on legs (Beron, 1975, Haitlinger, 2004). First record from Greece.
