What I hope is a reasonable translation reads:

75 Cremastogaster sordidula bogojawlenskii nov. sbsp.
Worker. The colour of the body is light, brownish-yellow with the occiput, the end of the flagellum, the transverse bands on the segments of the gaster and the apex of the gaster brown. The constriction between the middle and posterior alitrunk is very weak. Thin lateral, keel-shaped medulla of the middle back directly pass to the propodeum which has a wide base, short, rapidly tapering toward the end, sharp propodeal spines. The tooth on the underside of the 1st segment of the pedicel is very small. Gaster thick, convex from below. The whole body is more subtle and slender in comparison with the type. The distal hairs are very rare on the alitrunk dorsum, head, scape and legs. Head is rounder and smaller. Flagellum uniformly and gradually thickens toward the apex, forming a 2-segmented club. The length is 2.8-3 mm.
Male. The second segment of the pedicel is continuous, without a transverse furrow, convex from above. The cheeks are thin, narrow, with 2 denticles. Very sparse distal hairs, long on the gaster and short on the alitrunk and head. Alitrunk with longitudinal lateral rugae. With a black-brown head and alitrunk, with light yellowish mustache, mandibles and legs; gaster light brown with dark posterior border of segments. The veins on the non-coloured wings are largely atrophied. Antennae with 11 or 12 segments, of the same shape as the type. The length of 2.6 - 2.8 mm.
Location. Eastern Bukhara on the border with the Pamirs. The Darvaz Ridge, the village of Chil-Dara-Ishtiyon, along the Khingou River (the headwaters of the Amu-Darya River). Males and females, 14.VI.1898. (Bogojavlenskiy).
This is a typical mountain form. Makes nests under rocks.
I dedicate it to N.B.Bogojavlenskiy, an assistant professor of zoology at Moscow University who delivered a very interesting myrmecological collection from the Pamirs and their Eastern Bukhara.
This race is close to var. osakensis For. (from Japan), which was also distinguished by a light pale yellow body with a brownish-yellow crown and a posterior half of the abdomen; the head of osakensis is less rounded and more oblong than that of bogojawlenskii.
The type Cremastogaster sordidula is very close Madagascar view of Cremast. rasoherinae For., differing mainly by the special form of the segments of the pedicel (Forel 285, p. 194) and the Australian Cremast. pallidipes Mayr (= Cr. pallipes Mayr 512. p. 120, 516, p.107), in which the second segment of the pedicel has a longitudinal groove, as in Cr. scutellaris.

The synonymy of kosti perhaps is questionable as Ruzsky gave it as a variety sordidula whereas he described bogojawlenskii as a subspecies.

There are no type images of Cr. sordidula on Antweb. Cr. rasoherinae can be seen at  https://www.antweb.org/specimenImages.do?code=casent0101836. Cr. pallipes (uniformly yellow-brown) can be seen at https://www.antweb.org/specimen.do?name=casent0919692
