Two new species with peculiar pigmentation of the genus Homidia from Guangdong Province, Southern China are described here, Homidia chroma sp. nov. and Homidia leniseta sp. nov. H. chroma is characterized by chrome pigmentation on lateral side of terga, two macrochaetae on medial abdominal segment (Abd.) III and six macrochaetae on postero-medial Abd. IV, up to 68 sensory chaetae present on Abd. IV, and five apical smooth chaetae on posterior face of ventral tube. H. leniseta is easily identified by unique colour pattern, smooth labial chaetae l2, G1–4 and H1–3, and short trichobothria on Abd. II–IV. Illustrations of adults of this two new species, chaetotaxy of the first instar larvae of H. chroma and subadults of H. leniseta are provided herein.

Two New Species

Based on morphological and phylogenetic analyses (16S rRNA mtDNA), two new species of the genusLeptobrachellaare described from southern China, namelyL.yunkaiensisWang, Li, Lyu & Wang,sp. n.from Dawuling Forest Station of Guangdong Province andL.wuhuangmontisWang, Yang & Wang,sp. n.from Mt. Wuhuang of Guangxi Province. To date, the genusLeptobrachellacontains 68 species, among which 13 species are known from China. The descriptions of the two new species further emphasize that the species diversity of the genusLeptobrachellafrom China is still highly underestimated and requires further investigations.

This study describes two new species of freshwater crab of the genus Heterochelamon Türkay & Dai, 1997 from southern China, H. huidongense from Guangdong Province and H. jinxiuense from Guangxi Zhuang Autonomous Region. The two new species can be differentiated from congeners by characters derived from the shape of the epibranchial tooth, external orbital angle, cheliped proportions and structure of the male first gonopod. The present study brings the number of Heterochelamon species to seven. We used the mitochondrial 16S rRNA gene for a molecular analysis and the results are consistent with the morphological features that support the recognition of two new taxa.

Two New Species

Two new species of Macrostomum (Platyhelminthes: Macrostomorpha), M. shiyanensis n. sp. and M. lankouensis n. sp. are described from Shiyan Reservoir and Lankou Town. Morphological characteristics of the penis stylets and sperm, as well as the phylogenetic analysis using concatenated sequences of 18S and 28S rDNA genes support the establishment of these two new species and indicate that they are closely related to M. sinensis and M. heyuanensis described from different regions of Guangdong province. Finally, the progress of molecular phylogenetics of Macrostomum worldwide is also discussed.

Morphological Differences

Two new species of Lactarius from Dinghu Mountain, Guangdong Province in southern China were described based on both morphological characters and phylogenetic analysis of internal transcribed spacer (ITS) sequences. Lactarius verrucosporus sp. nov. is characterized by reddish brown pileus with white and decurved margin, pale cream lamellae, globose to subglobose basidiospores with isolated warts, thin pileipellis composed of globose subterminal cells and inflated terminal elements. Lactarius nigricans sp. nov. is recognized by greyish brown pileus, beige lamellae, amyloid basidiospores with high ridges, subcylindrical to subfusiform caulocystidia, thick pileipellis with long terminal cells. Both molecular and morphological analysis consistently confirm that L. verrucosporus and L. nigricans belong to Lactarius subgenera Russularia and Plinthogalus, respectively, and both species are distinct from all described species of these two subgenera. The morphological differences of these two novel species with their closely related taxa are discussed.

Two New Species

Two new nemourid species, Amphinemura meizhouensis sp. n. and A. tulipa sp. n., are described from Guangdong Province and Guangxi Zhuang Autonomous Region, respectively. Four larvae of the stonefly subfamily Amphinemurinae, A. bifascia Mo, Wang, Yang & Li, 2020, A. hamiornata Li & Yang, 2008, A. yao Mo, Yang, Wang & Li, 2017, and Indonemoura scalprata (Li & Yang, 2007) are described and illustrated on the basis of recently collected specimens from southern China. The female adult of A. hamiornata is also described from the type locality. Both new species are typical members of the A. sinensis (Wu, 1926) species group and the taxonomic relationships are discussed with related congeners.

Two morphologically distinct new species of Nanhaipotamon Bott, 1968, are described from Huizhou, Guangdong Province, southern China. The smooth carapace and lack of flagellum on the third maxilliped exopod immediately separate N. incendium n. sp. from all other known Nanhaipotamon. It is also the first species of this genus to be recorded from a relatively high altitude of 700 m a.s.l. Nanhaipotamon aureomarginatum n. sp. is externally much more typical of species of its genus but can be distinguished from congeners by its unique male first gonopod. The two new species are more or less sympatric with a morphological disparate congener, which we tentatively assign as N. aff. aculatum Dai, 1997 and N. aff. hongkongense (Shen, 1940), respectively, but with different habitats. A genetic analysis using the mitochondrial cytochrome oxidase subunit I shows that while the two new species are sufficiently distinct from other known species of Nanhaipotamon, they have extraordinarily close relationships with their respective sympatric congeners, which calls for further investigation. The ecology of these two new species are also noted.
