TL;DR: Idiosomal and leg chaetotaxy (including solenidiotaxy) are studied in Cheyletidae and a system of nomenclature is proposed, basically similar to that already used for Ereynetidae and Myobiidae.
Abstract: Idiosomal and leg chaetotaxy (including solenidiotaxy) are studied in Cheyletidae s. lat. A system of nomenclature is proposed for the idiosomal chaetotaxy. This system is basically similar to that already used by the author for Ereynetidae and Myobiidae.

TL;DR: In this paper, a chemically defined diet for ternal Tetranychus urticae females and males was used to achieve an increase in the fertility rate and an overall reproductive effectiveness.
Abstract: Teneral Tetranychus urticae females and males reared on a chemically defined diet initially achieved an oviposition rate of 0.4 eggs per female per day and an egg viability of 12 to 15% hatch. Reproduction was improved by making the following changes in the diet: decreasing total amino acids from 2% to 0.88% and total sugars from 4% to 1%; formulation of an amino acid mixture based on the analysis of sodium caseinate, a protein source superior to the initial amino acid mixture; decreasing major salts from 67.4 mgs to 33.7 mgs and increasing minor salts from 1.70 mgs to 3.40 mgs per 100 ml of diet. The final chemically defined diet did not increase the oviposition rate but gave a 56.68% egg hatch and an overall reproductive effectiveness 2.5 x as great as the initial diet.

TL;DR: A new genus and type species, Ophthalmodex artibei, are described from Artibeus lituratus, a Surinam bat, and this is the first demodicid discovered in the lacrimal gland complex.
Abstract: A new genus, Ophthalmodex, is characterized and erected, and a type species, Ophthalmodex artibei, described from Artibeus lituratus, a Surinam bat. These turtle-shaped mites are members of the family Demodicidae. They are remarkably modified for survival on the corneal surface and in the eyelid fornixes of the host mammal. In this latter locus, they consume epithelial cells. They also invade the lacrimal duct, plugging the lumen, destroying the epithelial cells and occasioning leucocyte infiltration in surrounding tissue. This is the first demodicid discovered in the lacrimal gland complex.

Laminosioptes hymenopterus Jones and Gaud, 1962 from Corvus-brachyrhynchos brachyrhynchos is transferred to Calamicoptes Lukoschus and Lombert, 1979 and redescribed. The new species are Fainocoptes zenaidurae ex Zenaidura macroura, Calamicoptes fringillae ex Pooecetes gramineus and Podicipedicoptes americanus ex Podilymbus podiceps.

TL;DR: Demodex cafferi n. sp. is described from the African buffalo and population studies of this new species suggests arrhenotoky (1:31, male: female), survivorship of Type III and plausible r-selection as mentioned in this paper.
Abstract: Demodex cafferi n. sp. is described from the African buffalo. Population studies of this new species suggests arrhenotoky (1:31, male: female), survivorship of Type III and plausible r-selection. A marked similarity, for mite morphology and pathogenesis, prevails between this species and D. bovis Stiles. Deposited ova are often in early division stages of embryo-genesis with occasional 2,4, and 8 cell holoblastic cleavage; these last are somewhat unusual departures from a typical meroblastic arthropod pattern.

TL;DR: All motile instars (larva, nymph, and adult) of three Parasitengona families, Erythraeidae, Trombidiidae, and Trombiculidae, were taken from pheromone traps designed to catch male southern pine beetles.
Abstract: All motile instars (larva, nymph, and adult) of three Parasitengona families, Erythraeidae, Trombidiidae, and Trombiculidae, were taken from pheromone traps designed to catch male southern pine beetles. All but one of 14 specimens were parasitic or attached to flying adult beetles. The larvae rode on all body areas and were active only during the warm months. One trap caught most of the mites. Although these mites occur infrequently during certain seasons? they may have a limited local impact.
