Biological notes. In late September 2014, tens of longicorn beetle larvae from Daiyunshan National Nature Reserve (Fujian, China) were found in the phloem of a plant ( Fagaceae Dumortier ) and reared in a laboratory, most of adults emerged in December 2014, but some in November 2014 (Mr. Shou-Ping Cai, personal communication).

Type specimens examined. Syntype: sex unknown ( BPBM), P. des jarres, 28. 3. 64 (handwriting on a rectangular white label with black border in black ink)/ Paracanthocinus laosensis , mihi typ, Breuning dét. (“ Paracanthocinus laosensis , mihi typ” handwriting and “Breuning dét.” printed on a rectangular white label in black ink; “mihi typ” is the abbreviation of “mihi typus ”, which means “my type ” in Latin).

Distribution. China (Fujian, Guangxi); Laos (Xieng Khouang).

Remarks. This species was originally reported from Laos ( Breuning, 1965a), and later reported from Fujian, China ( Hua, 1987); it is newly recorded from Guangxi, China. Breuning (1965a) described this species with lower lobes of eyes two times longer than genae, however, the first author found the lower lobes of eyes of this species distinctly longer than genae, but lower lobes of eyes not two times longer than genae after examining the specimens from China (Fujian and Guangxi).
