Massuria daizong Lin & Li 2023, sp. nov.

Massuria daizong Lin & Li, sp. nov. (Figs 65–67, 69G–H)

Etymology. The species is named after Dai Zong, one of the 108 outlaws in the classical Chinese literature Outlaws of the Marsh; noun in apposition.

Diagnosis. The new species is similar to M. bellula Xu, Han & Li, 2008 and M. ovalis Tang & Li, 2010 by the similar shape of the ventral and retrolateral tibial apophyses and the similar shape of the copulatory ducts and spermathecae. However, the male of the new species can be distinguished from M. bellula by the embolus arising at the clock 6:00 position (vs. clock 9:00 in M. bellula). The female can be distinguished from M. ovalis by the presence of an epigynal hood (vs. absent in M. ovalis).

Description. Male (holotype). Total length 2.99; carapace 1.30 long, 1.36 wide, opisthosoma 1.69 long, 1.34 wide. Eye sizes and interdistances: AME 0.05, ALE 0.06, PME 0.04, PLE 0.06, AME–AME 0.17, AME–ALE 0.11, PME–PME 0.17, PME–PLE 0.22, AME–PME 0.18, ALE–PLE 0.15. Leg measurements: I 5.24 (1.62, 1.84, 1.07, 0.71), II 5.16 (1.63, 1.86, 1.01, 0.66), III 2.71 (0.90, 0.97, 0.49, 0.35), IV 2.72 (0.91, 0.97, 0.46, 0.38).

Coloration (Fig. 69G). Carapace orange, with sparse spines. Chelicerae, endites and labium orange. Sternum paler orange. Legs I and II orange to red, others orange, with sparse spines and black setae. Opisthosoma pentagonal, orange, with sparse spines at edge. Spinnerets orange.

Palp (Fig. 65). Patella almost as long as tibia, with two ventral macroseta. Tibia with two ventral and three prolateral macroseta. Ventral tibial apophysis club-shaped, almost straight. Retrolateral tibial apophysis shorter than ventral tibial apophysis, terminal bifurcation, one club-shaped, other bent at end. Tegulum flat, disk shaped. Embolus spiraled, thin, base arising from clock 6:00 position, ratio of length of embolus to length of embolus base 6: 1.

Female (IZCAS-Ar44015). Total length 6.49; carapace 2.70 long, 2.66 wide, opisthosoma 3.79 long, 3.44 wide. Eye sizes and interdistances: AME 0.07, ALE 0.09, PME 0.05, PLE 0.07, AME–AME 0.17, AME–ALE 0.11, PME–PME 0.24, PME–PLE 0.31, AME–PME 0.24, ALE–PLE 0.20. Leg measurements: I 9.61 (3.04, 3.66, 1.93, 0.98), II 9.73 (3.11, 3.71, 1.90, 1.02), III 5.18 (1.68, 1.98, 0.86, 0.66), IV 5.52 (1.85, 2.05, 0.99, 0.63).

Coloration (Fig. 69H). Carapace white, with sparse spines, base of spines green. Chelicerae white with green spots. Endites, labium and sternum paler orange. Legs white to green. Opisthosoma pentagonal, white, five muscle attachment spots, edge wrinkled. Spinnerets white.

Epigyne (Fig. 66). Epigynal plate oval, with hood anteriorly. Copulatory openings laterally, inconspicuous. Copulatory ducts slightly curved, membranous. Spermathecae kidney shaped, posterior with a membranous tube connected to epigynal plate. Fertilization ducts directed toward clock 3:00 position from spermathecae.
