Dioxys lanzarotensis Tkalcu

Dioxys lanzarotensis Tkalcu, 2001: 49-50.

Diagnosis.

Small species very similar in morphology to D. atlanticus (Fig. 9A ) but differs by sparser punctures on metasomal terga (Fig. 9B ) and on clypeus. Only a single male (holotype) was recorded from the island Lanzarote of the Canary Islands (Spain) ( Tkalcu 2001). The holotype should be deposited in Übersee-Museum Bremen, Germany, but was discovered in the collection of Francisco La Roche in San Cristóbal de La Laguna, Tenerife, Spain. According to the studies of the holotype, this species is very similar to males of D. atlanticus but differs by the above reported characteristics, as well as several others (length and position of toothlike processes on S4 (Fig. 9D ), shape of head). It is certainly a separate species; however, its distribution area is restricted to one island.

Distribution.

Lanzarote, Canary Islands, Spain (Fig. 10 ) ( Tkalcu 2001).

Biology and hosts.

Unknown.

Conservation status.

Nieto et al. (2014) classified this species as DD - data deficient. It is the only category in which this species can be classified because we know only one specimen, the type.
