“…Mites of this genus usually occur on the ventral side of vanes of the wing and tail feathers, and most species are associated with passerines (Passeriformes) (Atyeo and Braasch 1966;Mironov 2012Mironov , 2017Mironov and OConnor 2014;Wang et al 2014;Mironov et al 2017). Despite also being found in most other proctophyllodine genera, such as Hadrophyllodes Atyeo, Hemipterodectes Berla, and Tanyphyllodes Atyeo, one of the most conspicuous characteristics of Proctophyllodes is the presence of a pair of lamellar projections at the rear end of males (Atyeo and Braasch 1966;Gaud and Atyeo 1996), which help in holding the couple together by increasing the surface area in contact between the male and female during copulation, or between the male and the tritonymph in precopulatory guarding (Byers and Proctor 2014).…”

A new feather mite species, Proctophyllodes pirangae sp. n. (Acari: Proctophyllodidae) is described from two tanagers of the genus Piranga Vieillot, 1808 (Passeriformes: Cardinalidae) in North America: the Scarlet Tanager, Piranga olivacea (Gmelin) and the Western Tanager, Piranga ludoviciana (Wilson) (Passeriformes: Cardinalidae) from North America. The new species belongs to the anthi species group and differs from the most similar species, Proctophyllodes polyxenus Atyeo and Braasch, by having in males, the aedeagus and genital sheath extending to or slightly beyond the level of setae g, the anterior margin of the opisthogastric shield shallowly concave, and its posterior margin nearly squareshaped, and the lamellae smaller; in females, both the lobar cleft and the transverse band of soft tegument at level of setae h1 are considerably narrower. www.zoobank.org/urn:lsid:zoobank.org:pub:29B3D157-8114-48EC-AF31-61A99F6D0C3B ARTICLE HISTORY

Proctophyllodid feather mites (400+ species) are permanent (full-time) symbionts commonly occurring on passerine birds. Phenotypic evolution of these mites appears to be greatly influenced by characters related to reproduction (>87.5% of a total of 32 taxonomically important discrete characters) and male genitalic characters (21.9%). Because sexual selection could the major evolutionary driver in this system, we test the theoretical expectation that genitalic or sexually dimorphic characters should evolve more rapidly and divergently then other characters. We inferred a time-calibrated molecular phylogeny (6 genes, 8571 nt aligned, no missing data) for 133 taxa of proctophyllodid mites and 40 outgroups. Comparisons of the average number of character state changes inferred on 10,696 Bayesian stationary trees indicate that male genitalic or sexually dimorphic characters do not evolve significantly faster than other characters (p=0.537 and p=0.819, respectively). However, among the male genitalic characters, a trait related to the relative length of the aedeagus experienced extremely fast rates of evolution and was detected as a statistical outlier. In this character, the transitions between short, long, and several intermediate states occurred in both directions. In contrast, the evolution of extremely long aedeagi (nearly as long as the body) occurred unidirectionally and irreversibly. This surprising result may be due to constraints imposed by the female spermathecal canal, which, in species where males have extremely long aedeagi, is also very long and may impede pumping sperm by short aedeagi. In proctophyllodid mites, extremely long aedeagi evolved independently five times in five different monophyletic lineages. Several of these lineages were lumped together by taxonomists to form easy-to-distinguish but apparently artificial species-groups. Male genitalic characters, thus, can introduce false synapomorphies that could affect morphology-based phylogenetic inference. For the most species-rich genus, Proctophyllodes, we develop a predictive classification of species-groups that reconciles molecular and morphological data.

Positive correlations between the shapes of male and female sexual structures can be interpreted as cooperative or as combative. In the feather mite genus Trouessartia Canestrini, 1899, the spermaducts of females range from entirely internal to extending externally for varying lengths, while male primary genitalia range from gracile to massive. Males also possess a pair of adanal suckers used to hold onto the dorsal surface of the female during copulation. In the area of this attachment, females exhibit ornamentation and have strongly developed dorsal setae (setae h1), which we hypothesized serve to weaken the male’s hold during copulation. In male and female Trouessartia from 51 bird species, we compared female external spermaduct length and male genitalic ‘massiveness’ and explored whether patterns of female dorsal ornamentation and/or h1 seta size correlate with male adanal sucker size. Our results indicate that females with longer external spermaducts are associated with males with relatively massive genitalia. However, we found no significant relationship between male adanal sucker size and female ornamentation or h1 seta size. Further information regarding how the genitalia interact during sperm transfer is necessary to interpret correlations in genitalia size and strong intersexual difference in dorsal ornamentation and seta size in Trouessartia.
