The original diagnosis of Coineau (1974a: 279) stated that mites of the genus Andocaeculus corresponds to caeculids with trichobothria present on all leg tarsi, with claws unequally sized, and having dorsal plates without intensive neotrichy. To these characters, we could add: gnathosoma not visible from above; only one seta Po (short or long); palpal femur with at most two setae; anal plate with two setae; femora divided into telofemur and basifemur on all legs; ω solenidion dorsally located, ε antiaxial and hidden, famulus κ” regressive; eupathidia of the typical ‘baguette de tambour’ of most of the genera of the family (Coineau 1974a) and (st) absent on tarsus II.</p></div>	https://treatment.plazi.org/id/2C0487DFFFA6FFC1F7FF5AB9076DF9EF	Public Domain	No known copyright restrictions apply.

The best fit models for each codon were SYM+G4 for COI1, GTR+F+G4 for COI2, and HKY+F+G4 for COI3. In the resulting tree (Fig. 60) the family, the genus Andocaeculus and the A. weyrauchi species group (only A. weyrauchi and A. burmeisteri sp. nov.) were recovered as monophyletic with high posterior probabilities (p=1, 0.99 and 1, respectively). In contrast to our previously published morphological phylogeny for the family (Porta et al., 2019), Neocaeculus did not occupy a derived position with respect to the clade [ Caeculus + Andocaeculus]. These results are, however, preliminary and will be tested using more terminals in the following part of the revision of the genus. The five exemplars assigned, on the basis of their morphology, to the species A. weyrauchi were recovered as a monophyletic group, which allows us to study the variation of morphological characters at the intraspecific level.</p><p>Remarks</p><p>On the d series setae of the legs and other characters of the A. weyrauchi species group</p><p>Under the optical microscope, leg setae of the series d in the A. weyrauchi species group resemble eupathidia by their shape and size. However, under inspection with SEM, the tarsal eupathidia present the typical ‘baguette de tambour’ shape (see for example Figs. 9I, 15, 43G), which clearly differ both in shape and size to the setae of the d series on other leg segments. In contrast, some setae on the larval stages (see Figs. 55–58) are similar, both in shape and size, to the d series setae on legs of the adults. Moreover, in the ontogeny of A. beatrizrosso sp. nov. and A. weyrauchi, some of these leg setae with typical regressive morphology become, in later stages, normal shaped setae (e.g. l’ on basifemur I), precluding any possibility that these setae were originally eupathidial. These facts reveal that these setae are regressive in the adult stage as consequence of a neotenic processes present in the group. A similar regressive process has been described for some setae of the same series for Microcaeculus hispanicus (Coineau, 1974a) .</p><p>Other neotenic processes present in this group are the morphology of aspidosomal setae, the presence of only one seta on the palpal femur and the presence of only 3 eupathidia on the palp tarsus of A. beatrizrosso sp. nov. In contrast, the low count of eupathidia on the legs could be the result of other process that have a wider occurrence within the genus (Ott &amp; Ott, 2014, AOP pers. obs.).</p><p>On the absence of (st) pair on tarsus II</p><p>About the (st) pair of setae on tarsus II, Coineau (1974a: 204) stated: “ Celles-ci [p’ p” setae] existent aux tarses I et II des Caeculidae (nous les notons st’ st”) et aux trois premiers tarses chez Anystis Granjean (1947 c, p. 88) alors qu’elles ne subsistente généralement qu’aux tarses I de la plupart des Acariens actinochitineux ”. [“These [p’ p” setae] exist on tarsi I and II of the Caeculidae (we denote them st’ st”) and on the first three tarsi in Anystis Grandjean (1947 c, p. 88) whereas they generally only subsist on the tarsi I of most actinochitinous mites”]. In contraposition to the Coineau statement, our examination of species of the genus Andocaeculus (all the described and several undescribed species) revealed that they all lack the (st) pair on tarsi II in all life stages. As this characteristic is not shared by other genera of caeculids, our preliminary phylogenetic analysis suggests that this is a synapomorphy of the genus Andocaeculus .</p><p>On the presence of solenidion φ on leg IV on A. weyrauchi .</p><p>The presence of a solenidion on tibia IV of species of the genus Neocaeculus from Oceania and South Africa has was used by Coineau (1967, 1974b) and Coineau &amp; Enns (1969) to support the genus Neocaeculus, which occurs in Oceania and South Africa. Outside Neocaeculus, it has only been registered in Microcaeculus (?) pica Otto, 1997 and, as a variation, on left tibia IV of the holotype of Microcaeculus sabulicola Franz, 1952 (Coineau, 1969) . As consequence of our phylogenetic analysis the presence of a solenidion on tibia IV of A. weyrauchi (Fig. 60, filled circles) is a primitive condition for the family Caeculidae, that was lost in the clade Caeculus + Andocaeculus (empty circles), and re-gained in A. weyrauchi . It is possible that the presence of the same derived condition in A. beatrizrosso sp. nov. could be conditioned by the psammophylous habits of both species, and, in consequence, further studies could bring some light on the function of these solenidia.</p><p>On the high variability of some characters on A. weyrauchi</p><p>Although our sampling of A. weyrauchi is restricted to type locality, we found remarkable variability in morphological characters in adults that are conserved in other species of the group: in dorsal chaetotaxy, the idiosomal setae b2 and c2 may be present or absent with almost equal probability; and some exemplars exhibit presence of neotrichy on the d2 sector. Likewise, some morphometric characters, such as the idiosomal and segment dimensions (Table 2), exhibit relatively high variability in their ranges. This variability can be illustrated using the quotient of the length of interval of the range over the midpoint of that interval. For example, in females of A. weyrauchi, for idiosomal length, where the range is 840–1110, this quotient is of 27.69%; and, for length of tibia III, where the range is 142–230, the quotient is 47.31%. In contraposition for females of A. burmeisteri these quotients values are of the order of 5 and 7%, for the lengths of the idiosoma and the tibia III, respectively. Variabilities of these characters, both idiosomal chaetotaxy and linear measures, have been used to distinguish species in another genus of the family (see keys for Caeculus on McDaniel &amp; Boe (1990), Bernard et al. (2020) and discussion on Porta &amp; Vazquez (2020)). In A. weyrauchi these characters are correlated in such a way that bigger females have, in general, more idiosomal setae that smaller ones. With the objective to study at least the variability of dorsal chaetotaxy we sequenced five exemplars showing different combinations of absence/presence of b2 and c2 setae and of neotrichy on the d2 sector, and incorporated their sequences in the phylogenetic analyses. The resulting tree (Fig. 60) as well as the intraindividual variation of gene sequences (intraspecific distance in A. weyrauchi max 5.18%, mean 2.17%; interspecific distance in Andocaeculu s min 12.1%; mean 22.09%) are consistent with the hypothesis that morphological variability could be assigned to intraspecific variability.</p></div>	https://treatment.plazi.org/id/2C0487DFFF8AFF8FF7FF594C015CF964	Public Domain	No known copyright restrictions apply.
