Description

Male. Colouration generally brown to dark brown (Due to being preserved in alcohol, the colours in the specimens appear faded in the photograph). Head pale yellow with black marking covering ocellar area (Fig. 1 A). Antennae and palpi dark brown. Pronotum dark brown with darker rugosities, anterior margin and stripes along median suture darker. Legs yellow brown with dark knees. Wings membrane grey, veins brown.

Tergum 1–8 unmodified (Fig. 1 B). Tergum 9 centre with sensilla basiconica. Hemitergal lobe slender, hook-like, apex slightly re-curved and nearly reaching the posterior margin of tergum 9.

Penis membranous (Fig. 2 ), with a ring-shaped group of large spines at the tip, interrupted by a spongy membranous projection in the middle. The base of the penis on the dorsal side is densely covered with small dot-like spines.

Female, egg and nymph: Unknown.

Etymology

The specific name refers to the type locality, Liyang City.

Distribution

This species is known only from the type locality, Liyang City of Jiangsu Province.

Taxon discussion

The penis of the new species is similar to that of K. hainana, Li, Wang & Yu, 2012 (see figs. 2–10 in Li et al. (2012)). Both species possess a spiny-free membranous region at the apex of the dorsal side of the endophallus, while the base is densely covered with small spines. Additionally, the ventral side of the endophallus features a spiny-free membranous area. However, in K. hainana , the basal spinule patch is divided by a funnel-shaped area on the dorsal surface, terminating subapically. The spines on the two lobes form a heart-shaped ring when viewed from the ventral side. In K. liyangensis , the dorsal side of the penis base is densely covered with small, dot-like spines. In the ventral view, there is a ring-shaped group of large spines at the tip, interrupted in the centre by a spongy, membranous projection. Currently, this new species is only known to inhabit Liyang City, Jiangsu Province, China. This discovery marks the first record of the Kamimuria in Jiangsu Province, enriching the study of insect diversity in the region.
