Heterozerconidae: A comparison between a temperate and a tropical species

The generic classification of millipede associated Heterozerconidae in the Oriental region is revised. The genus Allozercon Vitzthum is re-diagnosed and Asioheterozercon Fain is designated as an subjective junior synonym of Allozercon. Philippinozercon gen. nov., with the type species P. makilingensis sp. nov., is described for all instars. This genus may be endemic for the Philippines, but is quite widespread in that country. All immature instars are described, making this the second species of Heterozerconidae known for all instars. The morphology of the immatures is compared with that of immatures of the temperate species Narceoheterozercon ohioensis and unnamed species from Brazil and Thailand. All immatures were collected from millipede frass and litter, never from millipedes. Adults are associated with millipedes in the family Trigoniulidae (Spirobolida).

A revision of the genus Afroheterozercon (Acari: Heterozerconidae)

Six new species of Afroheterozercon, A. mahsbergi, A. sanghae, A. goodmani, A. gabonensis, A. tanzaniensis and A. madagascariensis, are described from a range of localities in sub-Saharan Africa, bringing the total number of described species in the genus to ten. These mites appear to be common on especially larger millipedes. Distribution data suggest locality, rather than host, specificity. A preliminary analysis of relationships provided relatively weak resolution and no evidence of geographically restricted lineages.

“…Immature life stages are described only for Narceoheterozercon ohioensis Gerdeman & Klompen 2003 and an undescribed Brazilian species (Krantz & de Moraes 2011). The immature stages are free-living and N. ohioensis is predacious (Gerdeman et al 2000;Gerdeman & Garcia 2009(2010; Krantz & de Moraes 2011). The cohort-level relationships are unresolved.…”

A new genus and species of Discozerconidae (Acari: Mesostigmata) from carabid beetles (Coleoptera: Carabidae) in New Zealand

2013

Berzercon ferdinandi gen. nov., sp. nov. (Acari: Mesostigmata: Discozerconidae) is described from carabid beetles in New Zealand. As in all Discozerconidae, Berzercon has large ventrally-directed opisthogastric suckers. However it is distinctive in its long marginal setae, tripartite gnathotectum, fused palp tibia and tarsus, the female's large dome-shaped genital shield and the male's highly modified hypostomal seta h1. This new species also represents the first Heterozerconina from an insect host.
