It has a unique character of genital papillae in transverse patches in both spermathecal and male pore regions (Figure 1A,B). It is endemic to the Central Mountain Range in southern Taiwan at elevations of 2000–2700 m. The body lengths and the number of genital papillae in the postclitellar region show a V-shaped cline with elevation; both peak at 2100–2300 m and decrease with the increase and the decrease in the elevation (Table 1). To date, there have been more than 100 species reported in the corticis - group. However, only Amynthas evansi (Beddard, 1900) from the Malay Peninsula was found to have numerous genital papillae. It has a row of eight papillae on each side in the intersegmental furrow of 7/8 (Beddard 1900). The position and arrangement of genital papillae are distinctively different between A. pavimentus and A. evansi.</p> <p>Amynthas pavimentus is easily distinguishable from the other three earthworms with multiple genital papillae reported from Taiwan, namely, Amynthas papulosus sauteri (Michaelsen, 1922), Amynthas tessellatus Shen et al., 2002 and Amynthas polyglandularis (Tsai, 1964). The former two species are sexthecate with three pairs of spermathecae in segments VI–VIII, whereas A. polyglandularis is quadrithecate with two pairs of spermathecae in segments VII and IX. The four species also vary in their geographical and altitudinal distributions in Taiwan: A. papulosus sauteri is distributed at elevations of 100–1000 m in northern, central and southern Taiwan, A. tessellatus is found at 700–3200 m in central Taiwan (Shen et al. 2002), and A. polyglandularis at 100–1000 m in northern Taiwan (Table 2).</p> </div>	https://treatment.plazi.org/id/03AC301E2A6DFFD0FED2DD86FCE5FA44	Public Domain	No known copyright restrictions apply.

A. libratus is distinguishable from A. pavimentus in the arrangement of genital papillae: the papillae of A. libratus are arranged in a single horizontal row at one side or both sides of setal lines or intersegmental furrows and no papilla around male pores (Figure 2A,B), whereas the genital papillae of A. pavimentus are patched between setal lines and intersegmental furrows, and often a few papillae are near the male pores (Figure 1A,B). The arrangement of genital papillae along setal lines and intersegmental furrows of A. libratus is fairly similar to that of the quadrithecate Amynthas kinfumontis (Chen, 1946) of China.</p> </div>	https://treatment.plazi.org/id/03AC301E2A69FFDCFEE6DD93FD2BFDA6	Public Domain	No known copyright restrictions apply.

It belongs to the diffringens (= corticis) species-group of the genus Amynthas (Sims and Easton 1972), and is closely related to A. uvaglandularis which is found at elevations of 1800–2300 m in central Taiwan (Tsai et al. 2004) and also at 1300–2300 m (this trip) in southern Taiwan. Amynthas biorbis differs from A. uvaglandularis by having no genital papilla in the preclitellar region, and only a pair of large and round papillae in XVIII located posterior to setal line and closely adjacent to male porophores (Figure 3A). Amynthas uvaglandularis has genital papillae in VIII, IX and XVIII, whose number and positions are highly variable (Shen et al. 2003).</p> <p>Amynthas biorbis is also fairly similar to A. corticis. However, the former is smaller, with a pair of large papillae medio-posterior to male pores and no genital papilla in the preclitellar region. These characters are consistent among the A. biorbis individuals and distinctly different from the variable papillae arrangements in the preclitellar and male pore regions of A. corticis (Table 3). Gates (1959) and James et al. (2005) reported A. corticis (= A. diffringens) specimens from Pingtung, southern Taiwan with fully developed reproductive organs showing no signs of male sterility (Table 3). Nevertheless, these authors are not quite sure whether their specimens are indeed the so-called A. corticis or a form closely related to A. corticis. The second author of this study has examined the A. corticis specimens described by James et al. (2005), and we have also collected specimens fairly similar to A. corticis but with fully developed reproductive organs from southern Taiwan (unpublished data). More specimens and further study are needed to solve this question.</p> </div>	https://treatment.plazi.org/id/03AC301E2A65FFDBFEFADA33FE0CFDFE	Public Domain	No known copyright restrictions apply.

(2005).</p> <p>Description</p> <p>External characters. Total length (clitellates) 140–195 mm. Weight 2.64–4.06 g. Segments numbering 87–136. Clitellum XIV–XVI, setae and dorsal pores absent, length 5.35–6.33 mm and width 5.28–5.42 mm. Prostomium epilobous. Three annulets (secondary segments) per segment in VII–XIII. Setal number 52–57 in VII, 65–78 in XX, and 12–14 between male pores in XVIII. First dorsal pore in 11/12. Spermathecal pores three pairs, small, buried deeply in intersegmental furrows of 6/7–8/9 (Figure 4A), distance between paired pores 0.26–0.29 body circumference ventrally apart. Genital papillae absent in the preclitellar region. Female pore single, midventral in XIV.</p> <p>Male pores paired in XVIII, 0.23–0.24 body circumference ventrally apart. Each pore on a round, white porophore 0.55–0.8 mm in diameter, surrounded by one or two shallow skin folds. Two pairs of large, round genital papillae, each 0.6–0.85 mm in diameter, slightly larger or as large as the porophore, with depressed centre 0.3– 0.45 mm in diameter, located slightly medially to the porophore at the presetal portions in XVIII and XIX (Figure 4B), and an additional pair in XX for paratype.</p> <p>Preserved specimens purple brown on head and dorsum, light brown on ventrum, and dark purple brown around clitellum. Setal ring white, distinctive.</p> <p>Internal characters. Septa 5/6–7/8 and 10/11 thick, 11/12–13/14 muscular. Nephridial tufts thick on anterior faces of 5/6/7. Gizzard in VIII–X, large, yellowish in colour. Intestine enlarged from XVI. Intestinal caeca paired in XXVII, extending anteriorly to XXIII or XXIV, each simple, slender, slightly wrinkled (Figure 4G). Oesophageal hearts in XI–XIII.</p> <p>Spermathecae three pairs in VII–IX, ampulla large, oval or peach-shaped, surface wrinkled, each 2.66–3.65 mm long and 1.63–2.54 mm wide, with a short, stout spermathecal stalk 0.35–0.57 mm in length. Diverticulum with an oval-shaped seminal chamber and a slender stalk 1.2–1.65 mm in length that are about twofold to more than threefold of the spermathecal stalk length (Figure 4C).</p> <p>Holandry. Testes large, two pairs in ventrally joined sacs in X and XI. Vas efferens connected in XII on each side to form a vas deferens. Seminal vesicles two pairs in XI and XII, large, occupying the full compartment, anterior pair larger, each vesicle with a round, finely folliculated dorsal lobe, darker in colour (Figure 4D). Prostate glands large, lobed, folliculated, in XVII–XX. Prostatic duct long, U-shaped in XVII–XVIII (Figure 4E). Accessory glands sessile, each oval-shaped, about 0.55 mm long, corresponding to its external genital papilla (Figure 4F).</p> <p>Etymology</p> <p>The name hongyehensis is given to this species with reference to the nearest village of its type locality.</p> <p>Remarks</p> <p>Amynthas hongyehensis sp. nov. is found on the east slope of the Central Mountain Range at elevations of 950–1000 m in southern Taiwan. It is a sexthecate earthworm belonging to the sieboldi species-group of the genus Amynthas (Sims and Easton 1972), and morphologically fairly similar to peregrine Amynthas hupeiensis (Michaelsen, 1895). Amynthas hongyehensis is distinguishable from A. hupeiensis in that it has paired presetal genital papillae between the setal line and intersegmental furrows in XVIII and XIX (or an additional pair in XX), whereas A. hupeiensis has paired genital papillae in the intersegmental furrows of 17/18 and 18/19 (Chen 1933; Tsai 1964). Furthermore, A. hupeiensis has a much higher setal number than A. hongyehensis with 100–121 in VIII and 79–88 in XX for the former (Tsai 1964) and 52–57 in VII and 65–78 in XX for the latter. Amynthas hupeiensis has a very long diverticulum (Chen 1933, p. 253, fig. 19E), while that of A. hongyehensis is much shorter than its ampulla.</p> </div>	https://treatment.plazi.org/id/03AC301E2A62FFC6FE1BDA11FE1FFA3B	Public Domain	No known copyright restrictions apply.
