Note. Publication and page sometimes misquoted as: “ Zool.Jb.Syst.61: 523.”

Distribution. China (Fuchou, currently Fujian).

Material examined. Hamburg type V6333 non-original label “ Darawida [sic] japonicus [sic] Type material ”, a mature specimen previously dissected and highly coiled in preservation. Hamburg V6196 “ Drawida? japonica ” also inspected being several small, undissected subadults and possibly neither types nor same species.

Description. Uniform buff in alcohol. Size 120 by 2-4 mm with 300 segments “ sehr ungenau!” (very inaccurate, Michaelsen, unmeasured by Gates) my current estimate of the highly coiled type is 110 mm and 333 segments. Setae closely paired (ca. ab=cd). Clitellum 10-13 at least. GMs in type in 7lhs&rhs, 9rhs, 10lhs&rhs, 11lhs plus two under male pores and one in 12 mid-ventral (total nine plus an accessory spermathecal gland; some possibly parasitic). Spermathecal pores in 7/ 8 in bc but closer to c. Male pores in 10/11 as overhanging flaps. Nephropores in cd in anterior. Spermathecal atrium present on long coiled duct but accessory glands only present on 8rhs with its own pore. Six gizzards reported (segments?) and other organs removed, “ otherwise as the typical form ”. The gut contains fine soil (i.e., geophageous).

Remarks. Drawida siemsseni ( Michaelsen, 1910) from Fuchow, China that Michaelsen (1931 b: 7) later said “ seems somewhat questionable ” and which Gates (1939: 414) very briefly redescribed from the Hamburg type [labeled as “V 6333 Drawida japonicus Mich. f. siemsseni . Tiensin, Futschau”] that was incomplete as the internal organs had been removed in the course of the original dissection and lost; he only said it differed in markings and porophores to D. japonica . A similar species from Ootacamund, Naduvatam and Coonoor, India is Drawida uniqua (Bourne, 1887) that was redescribed by Bourne (1894: 363) as unpigmented, 220 mm long with 316 segments and four or five gizzards in some of 15-21. No mention of GMs is made but Bourne (1894) put his long- er Moniligaster papillatus Bourne, 1887 that has long tubular papillae in connection with the pores in 10/ 11 in its synonymy. Note that Michaelsen (1907: 146; 1909: 118, 147) thought his D. nepalensis was similar but it is much shorter at 60 mm and it has markings typically in 7 and 8 but also near the male pores and a long, annulat- ed spermathecal atrium.

This type specimen of D. siemsseni is reinspected and sketched here providing for the first time details and a figure of the body. It is clearly a separate species from D. japonica having male pores in 10/11 and 6 gizzards, plus it is 110 mm long with ~333 segments. Unfortunately DNA results for the type were unsuccessful (iBOLD sample JET006-10), and no new material appears to have been recognized from China in recent times for comparison. The type locality is rather confused: Michaelsen had “Futschou” which is present day Fuzhou (dzNJƜ) in Fujien province (dzüñ) adjacent to Taiwan; but Gates gives “Tiensin, Futschau”which may refer to Tainjin City (RďƜ) in the North; however, since Herr G. Siemssen was the German Consul at Foochow (Fujian (Fukien) dz ü) this is the more likely location.
