New and redescribed species ofLedermuelleriafrom North America (Acarina: Stigmaeidae)

Abstract

UDEMANS (1923) 4 created the genus Ledermuelleria (originally Ledermiilleria) for seven species which he transferred from Caligonus, Raphignathus, and Stigmaeus. Additional species have been referred to the genus since then. The genus thus comprises a substantial array of species, which are very uniform in their generic features. Problems in identification arise because the species have been described one or two at a time by various authors. The consequence is that generic rather than specific characters are emphasized in their descriptions and illustrations. Hence it has seemed desirable to emend the prior descriptions of segnis, clavata, rhodomela, ottavii, lacuna, pectinata, and plumifer, and to prepare a key for the identification of females for the eleven species, including four new ones, considered in this paper. The following named species not described herein complete the roster of species for the genus. The list includes also several species originally described in other genera which are believed to be appropriate to Ledermuelleria.

Eustigmaeus segnis (Koch) (Acari: Stigmaeidae)’in deutonimf deri altındaki farat dişisinin bulgusu

“…Farklı olarak, ergine ait yeni deri üzerindeki dorsal ve ventral vücut kılları deutonimf evresine göre daha uzun ve güçlüdür. Normalde bu türün ergin olmayan evrelerinde coxal-sternal plaklar bölünmüş yapıda iken, ergin evrede bütün haldedir (Dilkaraoğlu 2016, Dilkaraoğlu et al 2016, Doğan 2005, Summers 1957, Summers and Price 1961. Ancak bu plaklar her iki faza ait deride ayrık olarak gözlenmiştir.…”
