New Species of the Genus Allopsontus Silv. (Archaeognatha, Machilidae) from the Caucasus and Tajikistan

Аннотация

Two new bristletail species of the family Machilidae are described: Allopsontus tyrnyauzi sp. n. from the Caucasus and A. zinchenkoi sp. n. from the Pamir-Alai Mountain system. The former species belongs to the subgenus Kaplinilis Mendes, 1990. Among the species described within this subgenus, numerous short, pigmented, appressed setulae on the underside of the 5-7th maxillary palpomeres and the 3rd labial palpomere in males are found only in A. tyrnyauzi sp. n. and A. bifarius (Wygodzinsky, 1970), the latter known from western Mongolia and Tuva. Allopsontus tyrnyauzi sp. n. differs from A. bifarius in the relatively short eye contact line, more dilated paired ocelli, urosternites with a right apical angle, the narrower sensory fields on the fore femora in males, and fewer paramere segments. Allopsontus zinchenkoi sp. n. belongs to the subgenus Anisopsontus Mendes, 1990 and differs from the other consubgeners in the color of the compound eyes, the width to length ratio of the paired ocelli, longer abdominal styli, larger sensory fields on the fore femora in males, and the relatively short ovipositor.
