“…This form of famulus has been reported in species of Crossacarapis (Ochoa and OConnor 1996), Flechtmannus (Moraes Lindquist and Lofego 2002), and Pseudacarapis trispicula Ochoa and Pettis . Three of these species are associated with bees, but adult females of Flechtmannus homalinotus Moraes, Lindquist and Lofego are found under the elytra of the curculionid beetle Homalinotus coriaceus (Gyllenhal).…”

Observations were made of cryo-preserved honey bee tracheal mites Acarapis woodi (Rennie) using scanning electron microscopy. We describe various new morphological attributes of A. woodi based on the ability of the cryo-technique to capture live mites in natural positions and observe the Low-Temperature Scanning Electron Microscopy (LT-SEM) photographs under a 3-D viewer. Most striking was the observation that each leg has the ability to independently twist its segments with the ambulacrum rotating a minimum of 180 degrees during locomotion; this is a more sophisticated form of locomotion than has been proposed for the Acari. Adult daughter mites are known to be the dispersal instar moving from the tracheal tube to the thoracic hairs of the bee and then transferring to a new bee. We hypothesize that adult tarsal claws and setae on the legs play a role in attachment to hairs during dispersal. However, our evidence is that none of the life stases use their tarsal claws within the tracheal tubes. Larvae were observed to be 'freely moving' within the tracheal system, their tarsal claws rendered inoperative due to an enlarged swollen pulvillar pad. The solenidia of leg I are now known to have striations and the famulus is bifurcated. The bifurcated famulus, solenidial striations, and segmentation of leg IV of females may have taxonomic implications in the family Tarsonemidae. The body and leg setae of adults appear to be used as a tactile tool to sense the amount of space within the tracheal tubes; most of the setae are oriented distally and may help the mite to measure the space or radius of the tracheal tubes. The modified caudal region of the male revealed remnants of the h1 and h2 setae and a smooth clean surface, void of a film, supporting that pharate nymphs are not attached in this species.

“…One important group is the family Tarsonemidae (Lindquist, 1986;Lin and Zhang, 2002), several species of which are known to be associated with bees (De Jong et al, 1982;Eickwort, 1988Eickwort, , 1994Ochoa and OConnor, 1996). The most economically important beeassociated tarsonemids are in the genus Acarapis, since all species are parasitic on honey bees, Apis mellifera L. Commensal associations include species such as Tarsonemus apis Rennie, 1921, on Apis spp.…”

“…These include Crossacarapis eickworti Ochoa and OConnor (1996) on Euglossa sp., Tarsonemus xTlocopae Magowski (1986) on Xylocopafrontalis (Olivier, 1789) and Pseudacarapis indoapis (Lindquist, 1968) on Apis cerana Fabricius (1793). Recently males and immatures of P. indoapis were recorded from 14 localities of Kerala and southern parts of Tamil Nadu, India in A, cerana hives (Sumangala, 1999).…”

A new tarsonemid mite, Pseudacarapis trispicula Ochoa and Pettisn. sp,, is described and illustrated from females phoretic on Apis mellifera L. collected from intercepted honey comb from Mexico. This is the first record of this genus in the Americas and the distribution and impact of this mite species in honey bee colonies remain unknown. The only other known species, Pseudacarapis indoapis Lindquist, has a host-specific association with Apis cerana Fabricius. RESUMEN-Una especie nueva de acaro tarsonemido, Pseudacarapis trispicula Ochoa & Pettis, es descrito e ilustrado de hembras foreticas en Apis mellifera L. recolectadas de panales con miel interceptados de Mejico. Este es el primer informe de este genera en el continente americana, la distribucion e impacto de esta especie acarina en eolonias de abejas domesticas no es conocida. La otra especie conocida, Pseudacarapis indoapis Lindquist, ha sido associada a Apis cerana Fabricius.
