Remarks

• Systematics: The most conspicuous diagnostic character of the species is the wide truncate conical spines on the dorsum. The closest species is A. devoniensis (Greem, 1896) which lives on several species of Ericaceae. The new species differs from A. devoniensis by having 6-segmented antennae; dorsal truncate setae much shorter, wider; and the number of setae on last abdominal tergit only about half the number on A. devoniensis. In the Nearctic region, three species seem to be similar to the new species: Acanthococcus arenosus (Cockerell, 1897), A. barri (Miller, 1991) and A. mackenziei (Miller & Miller, 1992). A. arenosus differs from A. thaleri in having 7-segmented antennae; truncate dorsal setae of two distinct sizes, all of them three times longer than wide,larger ones slightly curved and more abundant near the margins; and absence of cruciform pores. A. barri differs from the new species by having 7 segmented antennae; much more abundant dorsal setae in three sizes; absence of cruciform pores; and more robust legs. A. mackenziei differs from A. thaleri in having truncate setae two times longer than wide that are much more abundant on dorsum; absence of loculate pores with more than five loculi; tarsi much longer than tibiae.
• Structure: Female body elongate oval. Labium 3=segmented; basal segment not well developed, but with two setae on each side. Antenna 6 segmented; segment II with 1 sensory pore; all segments with a few hair-like setae. Eyes situation on venter near margin. Legs with a few hair-like setae, and with one sensory pore on tarsus. Multilocular pores distributed in sparse rows on all abdominal and thoracic segments.
• General Remarks: Detailed description and illustration in Szitz et al., 2011.
