Combined description (morphology with DNA barcode data) of a new quill mite Torotrogla paenae n. sp. (Acariformes: Syringophilidae) parasitising the Kalahari scrub-robin Cercotrichas paena (Smith) (Passeriformes: Muscicapidae) in Namibia.

ABSTRACT: A new quill mite species Torotrogla paenae n. sp. (Acariformes: Syringophilidae) parasitising the Kalahari scrub-robin Cercotrichas paena (Smith) (Passeriformes: Muscicapidae) in Namibia is described based on the external morphology and DNA barcode data (the mitochondrial cytochrome c oxidase subunit 1 sequences, cox1). Females of T. paenae n. sp. morphologically differ from the most similar species T. lusciniae Skoracki, 2004 by the total body length (780-830 vs 645-715 µm in T. lusciniae) and the presence of hysteronotal shields (vs absence), apunctate propodonotal and pygidial shields (vs punctate), apunctate coxal fields (vs punctate), the fan-like setae p' and p" of legs III-IV provided with c.10 tines (vs 14-15) and the length of setae si (140-180 vs 190-210 µm) and se (160-185 vs 210-225 µm). The male of T. paenae n. sp. morphologically differs from T. lusciniae by the lateral branch of peritremes composed of 4 chambers (vs 7-8 chambers) and lengths of setae ve (45 vs 70-75 µm) and se (120 vs 165 µm).

Project description:BackgroundThe microbiome is an integral component of many animal species, potentially affecting behavior, physiology, and other biological properties. Despite this importance, bacterial communities remain vastly understudied in many groups of invertebrates, including mites. Quill mites (Acariformes: Syringophilidae) are a poorly known group of permanent bird ectoparasites that occupy quills of feathers and feed on bird subcutaneous tissue and fluids. Most of the known species have strongly female-biased sex ratio, and it was hypothesized that this is caused by endosymbiotic bacteria. Previously, Anaplasma phagocytophilum (Foggie) and a high diversity of Wolbachia strains were detected in quill mites via targeted PCR screens. Here, we use an unbiased 16S rRNA gene amplicon sequencing approach to determine other bacteria that potentially impact quill mite biology.ResultsWe performed 16S rRNA gene amplicon sequencing of 126 quill mite individuals from eleven species parasitizing twelve species (four families) of passeriform birds. In addition to Wolbachia, we found Spiroplasma as potential symbiont of quill mites. Consistently, high Spiroplasma titers were only found in individuals of two mite species associated with finches of the genus Carduelis, suggesting a history of horizontal transfers of Spiroplasma via the bird host. Furthermore, there was evidence for Spiroplasma negatively affecting Wolbachia titers. We found no evidence for the previously reported Anaplasma in quill mites, but detected sequences of high similarity to the potential pathogens Brucella and Bartonella at low abundances. Other amplicon sequence variants (ASVs) could be assigned to a diverse number of bacterial taxa, including several that were previously isolated from bird skin. Further, many frequently found ASVs were assigned to taxa that show a very broad distribution with no strong prior evidence for symbiotic association with animals. We interpret these findings as evidence for a scarcity of resident microbial associates (other than inherited symbionts) in quill mites.
