Panteniphis

Family: Digamasellidae Evans

Panteniphis Willmann (=Lindquistoseius Genis, Loots & Ryke)

Diagnostic characters:

• Female with 3-4 pairs of setae on the sternal shield (st1 in membranous or st4 off shield)

• Dorsal shield entire in female (entire or divided in male; divided in deutonymph); setae j1, z1 and j2 minute; scleronoduli absent

• Tibia I and genu I each with 5/3 or 5/2 dorsal/ ventral setae 12 or 11 setae total); genu IV with 6 setae

• Sperm induction pore usually on leg III.

• Tectum with or with median subdorsal process and a pair of lateral tines

• Deutonymphs phoretic on insects.

Similar taxa.  Species of Panteniphis appear to be aberrant Rhodacaroidea referable to Digamasellidae because of their reduced leg setation and sperm induction pore on leg III.  Adults are strongly hemispherical in shape, but unlike somewhat similar Dendrolaelaspis species, lack posterior horn-like processes and have an entire dorsal shield.

Ecology & Distribution.  Deutonymphs are phoretic on carabid beetles.  Adults are free-living in soil,  Known distribution: Europe, North America, and Africa.
