Stoev, Pavel & Enghoff, Henrik, 2005, A new cave-dwelling millipede of the genus Bollmania Silvestri, 1896 from Yunnan, China, with remarks on the reduction of the second female leg-pair (Diplopoda: Callipodida: Caspiopetalidae), Journal of Natural History 39 (21), pp. 1875-1891 : 1881-1884

Caspiopetalum nodifrons Lohmander 1931, p 5 , Figure 2 , nomen nudum.

Bollmania nodifrons Lohmander 1933, p 49 , Figures 45–47.

Material examined

Six adult males, three subadult males, four adult females, one subadult female (adult male and adult female– NMNHS), Tajikistan, Hodzha-Moston Ridge, 1700 m alt., 13 April 1985, V. Dolin leg. ( ZMMU) .

Remarks

The examined specimens correspond well with the original description of the species, which was probably based on a not fully mature male. Having further material at our disposal we can improve the species diagnosis with the following characters: adult males with 58–60 pleurotergites+telson; females composed of 60 pleurotergites+telson; subadult males without a knob on the head; inner gonopodal coxal process (ip) longer than that illustrated by Lohmander (1933), sharpened, and apically curved as in B. oblonga . Female second leg-pair reduced ( Figure 14 ). The new locality is situated south of the town of Kurgan-Tyube, about 60–80 km east of the type and so far only known locality: Babatag Mt, SW Tajikistan.

Bollmania oblonga Golovatch, 1979

( Figure 15 )

Bollmania oblonga Golovatch 1979, p 990 , Figures 13–15 .

Material examined

Five adult males, 16 females (two males and three females – NMNHS), Tajikistan, Gazi- Malek, Isambai, 1600 m alt., 17–18 April 1985, V. Dolin leg. ( ZMMU) .

Remarks

This species is close to B. nodifrons , both species being characterized by the absence of a basal process of the solenomere, and in having a similar shape to the anterior part of the gonopod (compare Figures 13–15 in Golovatch 1979 with Figures 45–47 in Lohmander 1933). However, B. oblonga was distinguished by Golovatch by the absence of a knob on the head, the long antennae in males, comparatively small gonopods, a much longer distal process of the solenomere (e in Golovatch 1979, Figures 13–15 ), a much longer, S -shaped and apically swollen ip (hs in Golovatch 1979, Figure 13 ), and the existence of small swellings on the coxae of leg-pair 9 ( Golovatch 1979). Although the subadult B. nodifrons males are without a knob on the head, and the ip in adults is longer than that described by Lohmander (1933), both species are well distinguished by the size of the gonopods, the length of the distal process, the shape of the apical part of the gonofemur (with two small denticles in B. nodifrons ), and the shape of ip. The female second leg-pair is modified ( Figure 15 ). This species was hitherto known only from its type locality near Kondary Gorge, north of Dushanbe. Our material comes from Gazi-Malek, a mountain located about 150 km further south and very close to the known range of B. nodifrons .

Bollmania orientalis ( Silvestri, 1895)

Callipus orientalis Silvestri 1895, p 180 .

Bollmania orientalis: Silvestri 1896, p 150 .

Material examined

One adult male, Turkmenistan, Central Kopetdagh, ca 20 km south of Geok Tepe, Dushak Mt, towards Chuli, ca 2000 m alt., 21 April 1989, K. Mikhailov leg.; one adult male, three adult females (males and females– NMNHS), near Ashgabat, Firyuza Gorge , 14 March 1966 ( ZMMU) ; two adult males, three adult females, Kara Kala , 12 April 1984 .

Remarks

This species is confined to the region of Kopetdagh Mts, Turkmenistan. The new locality at Kara Kala is situated ca 190 km north-west of Ashgabat, thus extending the species range some 80–100 km to the north-east, but still within the limits of the mountain.
