A new quill mite species Neoaulonastus grewlingi sp. nov. parasitizing Australian endemic Falcunculus frontatus (Latham) (Passeriformes: Falcunculidae) is described. This new species differs from N. caligatus Skoracki by the following characters: apunctate pygidial shield and coxal fields I–IV, setae c1 1.4 times longer than d1, and lengths of setae ve 20, si 15–25, se 155–175 and c2 145–155. This is the first record of syringophilid mites from hosts of the family Falcunculidae and first register of Neoaulonastus genus in Australian region.
Mites of the family Syringophilidae are small and uniformly shaped arthropods, inhabiting feather quills of many birds species. Anomalies of setae arrangement are frequently observed in this mite group. Detailed investigation of nymphs and adults Torotrogla merulae Skoracki et al., 2000, reveals the most considerable variability of chaetotaxy aspect in this family. The purpose of our examination is to document anomalies in number and configuration of setae and to hypothesize the possible factors inducing them. As an explanation, a theory based on ‘fluctuating asymmetry’ is proposed.
A new quill mite species Neopicobia hepburni sp. nov. is described from the Ecuadorian Piculet Picumnus sclateri Taczanowski (type host) and the Olivaceous Piculet Picumnus olivaceus Lafresnaye (Piciformes: Picidae) from Peru. Females of N. hepburni are distinguishable from most similar species N. ea Skoracki et Unsoeld by the propodonotal shield divided into 3 sclerites, the pygidial shield with a vertical furrow and wing-like appendages, the presence of the genital lobes, setae f2 2.7 times longer than f1 and length ratio of ag1:ag2:ag3 equals 2:1:2. In females of N. ea, the propodonotal shield is entire, the pygidial shield is oval, without vertical furrow and appendages, the genital lobes are absent, setae f2 are 4.5–5.5 times longer than f1 and length ratios of ag1:ag2:ag3 are 2.2–2.7:1:3–3.2.
A new quill mite species Syringophilopsis davidi sp. nov. (Prostigmata, Syringophilidae) parasitizing Greater Short-toed Lark Calandrella brachydactyla (Leisler) (Passeriformes, Alaudidae) in Egypt is described. This new species is distinguishable from S. tyranni Bochkov and Galloway by 10–13 chambers of the peritremal lateral branches, setae se located slightly anterior to c1, and by setae ag2 about twice longer than the genital setae. This is the first record of this genus from the hosts of the family Alaudidae and in the Arab Republic of Egypt.
Two new quill mite species parasitizing sunbirds (Nectariniidae) are described: Aulobia nectariniae sp. nov. from the Olive-backed Sunbird Cinnyris jugularis (L.), from the Black Sunbird Leptocoma sericea (Lesson), and Aulobia anthreptes sp. nov. from Plain-throated Sunbird Anthreptes malacensis. The family Nectariniidae is a new host group for syringophilid mites.
