Treatment

Kuncosa gen. nov.

Type species.

Arctosa ningboensis Yin, Bao & Zhang, 1996 .

Etymology.

The generic name is a compound noun derived from the ancient Chinese mythical creatures ‘ kun’ (鲲) and ‘ - cosa’, a common ending for Lycosidae genera. The gender is feminine.

Diagnosis.

Kuncosa gen. nov. is similar to Loongcosa gen. nov. in having 2 pairs of spines in male palp tibia, a developed retrolateral tegular apophysis (Figs 4 A, B View Figure 4 , 5 A, B View Figure 5 , 8 A – E View Figure 8 , 10 A – E View Figure 10 , 12 A – E View Figure 12 , 14 A – E View Figure 14 ), a broad septum (Figs 4 C, D View Figure 4 , 5 C, D View Figure 5 , 9 C, D View Figure 9 , 11 C, D View Figure 11 , 13 C, D View Figure 13 , 15 C, D View Figure 15 ), but differs from the later by tibia as half-length of cymbium (Figs 4 A, B View Figure 4 , 5 A, B View Figure 5 , 8 A – C View Figure 8 , 10 A – C View Figure 10 ) (vs 1 / 3 length, figs 12 A – C, 14 A – C), the thin embolus lacking pars pendula (Figs 8 F View Figure 8 , 10 F View Figure 10 ) (vs broad with pars pendula, Figs 12 B, D, F View Figure 12 , 14 B, D, F View Figure 14 ), the comma-shaped basoembolic apophysis (BEA, Figs 8 F View Figure 8 , 10 F View Figure 10 ) (vs bifurcated, Figs 12 A – F View Figure 12 , 14 A – F View Figure 14 ), the strong and triangular terminal apophysis (TA, Figs 8 F View Figure 8 , 10 F View Figure 10 ) (vs thin, and finger-shaped, Figs 12 F View Figure 12 , 14 F View Figure 14 ), the tegular apophysis present (TeA, Figs 4 A, B View Figure 4 , 5 A, B View Figure 5 , 8 A – E View Figure 8 , 10 A – E View Figure 10 ) (vs absent), the bifurcated retrolateral tegular apophysis (RTeA, Figs 4 A, B View Figure 4 , 5 A, B View Figure 5 , 8 A – E View Figure 8 , 10 A – E View Figure 10 ) (vs strong sclerotized and grooved, Figs 12 B – E, G View Figure 12 , 14 B – E, G View Figure 14 ), truncated posterior margin of septum (Figs 4 C, D View Figure 4 , 5 C, D View Figure 5 , 7 View Figure 7 , 9 C, D View Figure 9 , 11 C, D View Figure 11 ) (vs with a tongue like apophysis, Figs 13 C, D View Figure 13 , 15 C, D View Figure 15 ).

Description.

Carapace brown with light median band. Eyes region black. Fovea vertical. Cervical groove and radial furrows indistinct. Chelicerae elongate, brown, with 3 teeth on both margins. Labium yellow brown, with dark base. Endites yellow brown. Sternum brown and scutellate, with sparse black setae. Legs brown, with black pigmentation. Leg formula: 4132. Opisthosoma oval. Dorsum dark brown, with lanceolate cardiac mark in anterior half, and black irregular markings in posterior half. Venter brown.

Palp (Figs 4 A, B View Figure 4 , 5 A, B View Figure 5 , 8 View Figure 8 , 10 View Figure 10 ): Tibia with 2 pairs of spines, and rounded disto-dorsal edge. Cymbium asymmetric, with short tip and lacking claws. Sperm duct weavy. Tegulum with long tegular apophysis (TeA) and short bifurcate retrolateral apophysis (RTeA). Conductor and median apophysis lacking. Embolic division complex, palea absent, terminal apophysis (TA) triangle- or fingernail-like, Basoembolic apophysis (BEA) strongly sclerotized Embolus needle-shaped, originated from proventral side, lacking pars pendula and with abrupt tip.

Epigyne (Figs 4 C, D View Figure 4 , 5 C, D View Figure 5 , 7 View Figure 7 , 9 C, D View Figure 9 , 11 C, D View Figure 11 ): Epigynal plate wider than long, fovea indistinct, covered by broad septum and oval. Stalk of spermatheca (SS) C- or S-shaped, head of spermatheca (HS) suboval.

Composition.

Kuncosa fujiii ( Tanaka, 1985) , K. hikosanensis ( Tanaka, 1985) , K. kwangreungensis ( Paik & Tanaka, 1986) , K. ningboensis ( Yin, Bao & Zhang, 1996) and K. zhui ( Yu & Song, 1988) .

Distribution.

China (Anhui, Chongqing, Guizhou, Hubei, Hunan, Jiangxi, Jiangsu, Zhejiang), southern part of Japan and Korea. (Fig. 16 View Figure 16 )

Remarks.

Although the types of Arctosa kwangreungensis Paik & Tanaka, 1986 were not examined, it is clear from the descriptions in Paik and Tanaka (1986) that this species belongs to the Kuncosa .
