Chaussieria domestica (Koch 1847) ♂ (Acari Trombidiformes Anystoidea Anystidæ Erythracarinæ Erythracarini)

Illustration for a comparative ecophylogenetic analysis of local myrmecofaunas, based on r/K selection theory and intra / interspecific parabiosis / lestobiosis, particularly focused on allochthonous and invasive species.

 

[Chaussieria Oudemans 1937: 10 (IT: 1) spp]

 

Chaussieria adults & nymphæ can be distinguished from all other Erythracarinæ by tarsi I-III divided into a basitarsus and an unsegmented telotarsus by a narrow flexible band of wrinkled cuticle; LIII distinctly shorter than LII. Larvæ, nymphæ & adults also have trichobothria sci approximately aligned with setæ sce. C. domestica can be distinguished from its congeners by having a palp tarsus that is longer than the rest of the palp; also diagnostic is the combination of 5-6 setæ on trochanter I, 11 setæ on genu IV, 6 setæ on basifemur IV. Cfr. notes¹ over the above image.

 

NOTES

 

1. TBL 0.8 mm; 2 t-sci aligned with 2 s-sce; 2 postocular subcuticular granular swellings, probably sensory organs or "megaocelli"; LIII distinctly shorter than LII.
