Abstract
A new genus and species of digamasellid mites is described based on adult females and males. Bulbolaelaps bossei n. gen., n. sp. was collected from the fruiting bodies of gilled fungi on a tree trunk in Zanjan province, Iran. The new genus can be distinguished from the other genera of Digamasellidae by having a bulbous swollen protuberance on the venter of the palptrochanter; corniculi weakly formed and epistome weakly sclerotised; hypostomal setae h1 and h2 positioned more or less transversely; deutosternal groove narrow with limited number of denticles; ventral base of female cheliceral digit with a spine-like projection; and setae ad1 and pd1 tarsi II–IV narrowly lanceolate apically.
Highlights
The family Digamasellidae was first erected by Evans (1957) and fully defined by Lindquist (1975) based on a limited number of genera
The purpose of this study is to described a new genus and species of digamasellid mite found in association with gilled fungi from Iran
Type species: Bulbolaelaps bossei Diagnosis Podonotal and opisthonotal shields separated in both sexes; in males, opisthonotal shield fused with opisthogastric shield; scleronoduli present; almost all dorsal shield setae barbed, most of them apically bulbous; sternal seta St3 migrated inwards; palps with bulbous swollen protuberance on the venter of the palptrochanter; corniculi weakly formed and epistome weakly sclerotised and fimbriated dorsally; hypostomal setae h1 and h2 aligned more or less transversely; deutosternal groove narrow; ventral base of female cheliceral digit with a spine-like projection; setae ad1 and pd1 on legs II–IV narrowly lanceolate apically
Summary
The family Digamasellidae was first erected by Evans (1957) and fully defined by Lindquist (1975) based on a limited number of genera. Castilho et al (2012) listed 13 genera considering Dendrolobatus Shcherbak, 1983 and Lindquistoseius Genis, Loots & Ryke, 1968 as valid genera. They briefly defined the family Digamasellidae as: With two-tined palp tarsal claw; most genera with podonotal and opisthonotal shields separated; generally with scleronoduli; without desclerotised punctae bands on dorsal and ventral shields; with seta St4 on sternal shield; tibia I with 5 dorsal setae; and genu and tibia IV with 6 to 8 setae each
