The genus Scolopendrellopsis Bagnall, 1913 is recorded from China for the first time and Scolopendrellopsisglabrussp. n. is described and illustrated. The new species is characterized by the short central rod on head, third tergite complete, four kinds of sensory organs present on antenna, and the cerci rather short and covered with a low number of straight setae.

Symphylella minutasp. nov. and Symphylella communasp. nov. from China are described and illustrated. Symphylella minutasp. nov. is characterized by the delicate and minute body, a well-developed and thin central rod with a vestige of a transverse suture in the middle, eight setae on the first tergite, pointed processes on the tergites, and short cerci with sparse setae. Symphylella communasp. nov. is characterized by the chaetotaxy of the first tergite with 4+4 setae, processes of the tergites somewhat longer or the same length with broad, most of lateromaginal setae long, anterolateral setae of tergites 2–4, 6, 7, 9, and 10 distinctly longer than other lateromarginal setae, approximately as long as the process of the same tergite, and cerci with numerous subequal and slightly curved setae. In addition, the chaetotaxic variation on the tergites, the distribution, the habitat, and the feeding habit of the genus Symphylella are discussed.

The Symphyla of Tibet are studied for the first time. Symphylellamacroporasp. n. and Symphylellazhongisp. n. from southeastern Tibet are described and illustrated. Symphylellamacroporasp. n. is characterized by large, elongated oval openings of the Tömösváry organ with its inner margins covered by minute irregular teeth, rudimentary spined sensory organs present on the dorsal side of most antennal segments, and cerci with numerous long and slightly curved setae. Symphylellazhongisp. n. is characterized by a globular Tömösváry organ with a small and roundish opening, mushroom-shaped sensory organs present on apical antennal segments, and by having tergal processes longer than their basal width with ovoid swollen ends. The newly described species are compared to the morphologically closest congeners: S.javanensis, S.asiatica, S.multisetosa, and S.simplex. A key for 43 species of the genus is also provided.

The genus Millotellina is recorded from China for the first time. Two new species, Millotellina centralis sp. n. and Millotellina bambusinus sp. n., from Guangxi Province of Southwest China are described and illustrated. Millotellina centralis sp. n. is characterized by the presence of single median ventral processes posterior to the coxal sacs of legs 4–10, half-way between successive pairs of legs and located in the center, and a thick frontal seta on the first leg. Millotellina bambusinus sp. n. is characterized by the single median ventral processes inserted between the coxal sacs of legs 5–10, palp of the first maxilla with three pointed branches, and cerci narrowed abruptly in the distal part. An updated key to the species of the genus is also provided.

Symphylella macrochaetasp. nov. and Symphylella longispinasp. nov. from China are described and illustrated. Symphylella macrochaetasp. nov. is characterized by 10 extremely long macrosetae arranged as 4/4/2 on the frons, tergites with broad triangular processes, and 4+4 setae on the first tergite. Symphylella longispinasp. nov. is characterized by a thick and prominent labrum, distinctly long proximal spines on the mandible, eight macrosetae arranged as 4/2/2 on frons, 3+3 setae on first tergite, and narrow triangular processes on the tergites. Detailed comparisons of the new species with similar species are presented. In addition, the frons chaetotaxy of Symphylella is illustrated and discussed for the first time and proposed as a significant diagnostic character for the taxonomic study of the genus.
