Type material.
Holotype. CHINA • 1 ♂; Hunan Province, Huaihua City, Xupu County, Lingcui Mountain Park; 27.9074 ° N, 110.5778 ° E, el. 214 m a. s. l.; 15. viii. 2019; W. C. Li, J. B. Yang leg. (DNA no. LCS 2020, Prep. slide nos. L 2046 - L 2048). — Paratypes. • 2 ♀♀; same data as the holotype (DNA no. LCS 2008). CHINA • 1 ♂, Hunan Province, Loudi City, Xinhua County, Shizi Mountain Park; 27.7311 ° N, 110.3338 ° E, el. 235 m a. s. l.; 16. vii. 2019; W. C. Li, J. B. Yang leg. (DNA no. SZS 1901, Prep. slide nos. L 19034 - L 19036).
Diagnosis.
Pereonite 1 slightly sinuous on posterior margin of epimeron, postero-lateral corner nearly right-angled; pleopods 1, 3-5 exopods out curved on outer margins; pleopod 1 exopod with outer lobe much longer than inner lobe.
Description.
Body length of males 4.6-6.9 mm, of females 5.51 mm. Color in alcohol blackish brown, dorsum slightly granulated, bearing irregular white muscle spots. Pereonite 1 slightly sinuous on posterior margin of epimeron, postero-lateral corner nearly right-angled (Fig. 6 E). Noduli laterales as in Fig. 10 A. Telson triangular, length about two thirds as long as width, lateral margin concave, apex blunted round; uropod exopodite about two and half as long as basipodite (Figs 6 E, 10 A). — Cephalon with arched median lobe, median lobe slightly longer than lateral lobes (Figs 6 E, 10 A). Antennula with several aesthetascs on distal tip of third article (Fig. 10 B). Antennal flagellum with first segment about third as long as second one (Fig. 10 C). — Pereopod 1 with brush of long setae on carpus and merus (Fig. 10 D). Pereopod 7 ischium with deep depression on rostral surface, carpus slightly expanded on dorsal margin (Fig. 10 E). — Pleopods 1-5 exopod with Protracheoniscus - type pseudotrachea (Fig. 10 F-J). — MALE: pleopod 1 exopod bilobed at posterior tip, outer lobe much longer than inner lobe, endopod with broad basal part, narrowed towards beak-shaped posterior tip (Fig. 10 F); pleopod 2 endopod styliform, a bit longer than exopod (Fig. 10 G).
Etymology.
The new species is named after Dr. Christian Schmidt (Senckenberg Naturhistorische Sammlungen Dresden, Germany), who contributed profoundly to systematic research in woodlice; noun (name) in the genitive case.
Remarks.
The new species is very similar to L. nudus Li, 2017 in having the outer lobe of the pleopod 1 exopod much longer than the inner lobe. But it can be distinguished by the slenderer body shape and less developed epimeron (Fig. 6 E versus 6 F). Furthermore, the molecular data recognized both species as distinct taxonomic entities (Fig. 5).
