Echinovelleda guoliangi ( Huang, Huang & Liu, 2020) comb. nov.

( Figs. 2 , 17 , 24 , Map 1 )

Propedicellus guoliangi Huang, Huang & Liu, 2020: 525 . Type locality: Pingbian, Yunnan, China.

Material examined. China (Yunnan): 1 male, China, Yunnan, Malipo , Xiajinchang , Laoshan , 1,630 m, 2022. VIII.10, leg. Wen-Xuan Bi (CBWX); 1 female, ditto except 1,700 m, 2022.VIII.8, leg. Wen-Xuan Bi ( CBWX) ; China (Guangxi) : 1 male, China, Guangxi, Fangchenggang, Naliang, 2020.VI, local collector ( CMC) .

Complementary description. Male ( Fig. 2 ). Endophallus ( Fig. 18 , distal part slightly broken) smoothly Sshaped, moderately long and slender; MPH subdivided into MT+CT and PB; MT+CT roughly straight, moderately constricted near it midlength, provided with one ltc at each side distally; PB cylindrical in basal half, with moderately developed anterior bulb; APH subdivided into ab and bb; ab conical shaped; bb weakly developed, provided with a small ventral appendix; gn situated at apex of bb.

Distribution ( Map 1 ). China: Yunnan (Pingbian County; Malipo County), Guangxi (new Province record, Fangchenggang City).

Remarks. Some diagnostic characters employed by Huang et al. (2020) to separate this species from E. vitalisi , are observed to be intraspecifically variable, such as the shape of pronotal discal maculae, the punctures on head and pronotum and the number of elytral tubercles, or usually applied for a higher classification instead of specific, i.e., the veinal characters ( Kukalová-Peck & Lawrence 1993, 2004). Therefore, this species is merely accepted to be distinguished from E. vitalisi by the pronotal lateral spines mostly covered with dense light colored pubescence, instead of absent, subapical dorsolateral carinae of elytra (as “marginated portion” in Huang et al. 2020) less prominent, not covering elytral lateral margins in dorsal view. It can be further recognized among the congeners (except for E. mumuae or E. yanziae ) by the male endophallus with ab pronounced and provided with a small ventral appendix.
