- <p><b><i>Gnathocinara boi</i> Wang & Zolotuhin, <i>in</i> Wang <i>et al.,</i> 2015</b></p><p><i>Gnathocinara boi</i> Wang & Zolotuhin, 2015; Wang <i>et al.</i>, 2015, <i>Zootaxa</i>, 3989 (1): 49.</p><p>Type locality: Dongzhong Forest Farm, Shangsi County, Shiwandashan National NR, Fangchenggang City, Guangxi Zhuang Autonomous Region, China.</p><p><b>Taxonomic note.</b> The original description of the male genitalia presented by Wang & Zolotuhin <i>in</i> Wang <i>et al.</i> (2015) is demonstrably inconsistent with the established generic morphology, necessitating a revised interpretation. Firstly, the dorsal processes of the uncus, which are typically observed as distinct, laterally positioned lobes or processes in this genus, were incorrectly characterized as a bifid uncus. Secondly, the valva was erroneously identified as the costal process and thirdly, the vincular process, a feature arising from the vinculum, was mislabelled as the sacculus of the valva. These misidentifications reflect a significant deviation from the standard morphological understanding of the genital armature in this genus. Furthermore, a critical error was detected in the illustration of the 8th sternite. Specifically, the image provided for the newly described species (Wang <i>et al.</i> 2015, Figure 18F) appears to be an incorrect substitution. Comparative analysis reveals that this image closely resembles the 8th sternite of <i>G. situla</i> (Wang <i>et al.</i> 2015, Figure 18D or 18E), suggesting a potential transposition of figures during publication. While the associated textual description of the 8 th sternite in Wang <i>et al.</i> (2015) aligns with our observations, the corresponding illustration is clearly erroneous.</p><p>Efforts to resolve these discrepancies through direct communication with the first author of Wang <i>et al.</i> (2015) yielded no response. Consequently, given the observed inconsistencies and the lack of clarification from the original authors, we present herein a detailed redescription of the male genitalia for this species, incorporating accurate morphological interpretations and providing corrected illustrations. This redescription aims to rectify the errors in the original publication and provide a reliable foundation for future taxonomic and phylogenetic studies.</p><p><b>Redescription.</b> Male genitalia with uncus long, digitate with two latero-dorsal horn like processes; gnathos thin, short; valva simple, long, curved; vinculum with two caudad directed strong processes with toothed ends, ventrally fused up to midway; saccus well developed, swollen basally; aedeagus slender and long with bifid arms at base, apical area with small hook like structure, vesica with minute cornuti. The 8 th tergite goblet-shaped, anterior margin with two long, thin, laterally directed bars. The 8 th sternite broad, posterior margin medially invaginated, Ushaped, apically with two pairs of processes, the outer bifid, broad and apically blunt, the inner longer, curved and sharply pointed; anterior margin with two long processes, apically curved outward and uniformly expanded.</p>
