Two new species of Lepidocyrtus Bourlet s. lat.

. Two new species of the genus Lepidocyrtus Bourlet, 1839 from southern China are described here: L. ( Acrocyrtus ) huizhouensis sp. nov. from Guangdong Province and L. ( Setogaster ) wanningensis sp. nov. from Hainan Province. Lepidocytus ( Acrocyrtus ) huizhouensis sp. nov. is the fourth species of the subgenus reported from China and L. ( Setogaster ) wanningensis sp. nov. is the first report of the subgenus from China.


Introduction
Lepidocyrtus Bourlet, 1839 s. lat., the second largest genus of the subfamily Lepidocyrtinae Wahlgren, 1906, is characterized by having four-segmented antennae, 8+8 eyes, a bidentate mucro with a basal spine, finely ciliate scales and often the absence of dental spines.It contains eight subgenera (Cipola et al. 2018) and their main differences are listed in Table 1.
The subgenus Acrocyrtus Yosii, 1959 is characterized by the presence of pointed basal tubercles on the dentes and of ciliate scales on body (Xu et al. 2013).Among the 28 species of the subgenus, 18 were described or reported from Southeast Asia, including Malaysia, Singapore, Indonesia and Vietnam.Five are from India and three from Oceania.Three are from China: L. (A.) heterolepis (Yosii, 1959) from Taiwan and Hongkong, and L. (A.) finis Xu et al., 2013 and L. (A.) zhujiensis Xu et al., 2013 from Zhejiang Province.
The basal dental tubercles of the subgenus Setogaster Salmon, 1951 are rounded and scales are often absent on antennae I and II and the legs (Cipola et al. 2018).Among the 15 species of the subgenus, five were described from Singapore and Indonesia.Four are from Brazil and Peru, three from India, two from America and one from Rwanda (Bellinger et al. 1996(Bellinger et al. -2019)).No reports exist for China.In this paper, two new species of the genus Lepidocyrtus are described from southern China: L. (Acrocyrtus) huizhouensis sp.nov.from Guangdong Province and L. (Setogaster) wanningensis sp.nov.from Hainan Province.

Material and methods
Specimens were cleared and mounted under a coverslip in Marc André II solution and were studied with a Leica DM2500 microscope.Photographs were taken with a mounted Leica DFC300 FX digital camera and enhanced in Photoshop CS2 (Adobe Inc.).The nomenclature of the dorsal chaetotaxy of the head follows Jordana & Baquero (2005) and that of the interocular chaetae follows Mari-Mutt (1986).Labial chaetae are designated following Gisin (1967) and the labial papillae and maxillary palp following Fjellberg (1999).Tergal chaetae of the body are designated using the system of Szeptycki (1979) and specialized chaetae (S-chaetae) using Zhang & Deharveng (2015).

Subgenus
Dental tubercle

Scales on
Ant. I-II Scales on legs Apical bulb on Ant.IV  SCALES.Scales ciliate, oval to circular, present on Ant.I-II, both sides of head, thoracic and abdominal tergites, femora and tibiotarsi, and ventral side of furcula.Other appendages without scales.
SCALES.Scales lightly ciliate, oval to circular, present on Ant.I, both sides of head, thoracic and abdominal tergites, femora and tibiotarsi, and ventral side of furcula.Other appendages without scales.

Remarks
The new species is most similar to the species Lepidocyrtus (Setogaster) merapicus Yoshii & Suhardjono, 1989 and L. (S.) sotoi Bellini & Godeiro, 2015 in colour pattern since no blue pigment is present on their body tergites, but the colour pattern on the antennae, scales on Ant.I, femora and tibiotarsi, as well as the shapes of the prelabral and labial chaetae and the inner teeth on the unguis are different (Table 3).
DiagnosisBlue pigment distrubuted on antennae, head, body tergites, manubrium, femora and tibiotarsi.Irregular patches present on Th.II-III.Scales present on Ant.I-II, femora and tibiotarsi.Ant.III with 6 to 11 rods distally.Labial chaetae M and R ciliate, m, e, l 1 and l 2 smooth.Frontal area of dorsal head with several clubbed chaetae.C1 on Abd.IV smooth mic.Subapical tooth of mucro much smaller than apical tooth.
DiagnosisScales present on body; mucro bidentate and accessory spinelet may be present; pointed tubercles present and spines absent on dens.
DiagnosisDark blue pigment present on Ant.III-IV and Ant.II distally.Scales present on Ant.I, femora and tibiotarsi.Labial chaeta M 1 ciliate, r reduced, others smooth.C1 on Abd.IV ciliate mac.Dental tubercle rounded.
