Material Examined. Holotype: CHINA: Yunnan: Gongshan Co. Dulongjiang Township, Haban Falls 0.5 airkm from Qinlangdang village along Dulong Jiang , 27.67934°N, 98.27291°E, 1265 m, 1 September 2006, subtropical evergreen broadleaf forest, sifting leaf litter, J.A. Miller, D.H. Kavanaugh, JM06090105 (CASENT 9024389, HNU), 1 ♀.

Etymology. Formed from the Chinese words for fire (huǒ) and dog (gǒu), referring to the element and animal of the Chinese zodiac when this species was collected.

Diagnosis. Distinguished from M. nujiang by the shape of the spermathecae, transversely ovoid in M. huogou ( Fig. 43I ), bulbous in M. nujiang ( Fig. 43G ), by the separation of the membranous copulatory ducts in the posteromedial region ( Fig. 43I ; justaposed in M. nujiang , Fig. 43G ), and by the presence of a posterior abdominal tubercle in M. nujiang , absent in M. huogou .

Description. Carapace brown. Sternum dark gray with lighter patches down midline and anterolaterally. Legs light brown, darker distally on tibiae, metatarsi, and tarsi. Abdomen dark gray with tan and white spots; posterior tubercle absent.

Vulva: Spermathecae transversely ovoid, copulatory duct adjacent to spermathecae less strongly sclerotized than spermathecae. Fertilization ducts run posteromesally then turn anteriorly. Membranous copulatory ducts in posteriomedian region separated ( Fig. 43I ).

Female (holotype): Total length 0.92, carapace 0.44 long, 0.39 wide, clypeus 0.09, sternum 0.26 long, 0.27 wide, coxa IV separated by 2.08 times their width. Macrosetae: Leg I: patella d1, tibia d1; Leg II: patella d1, tibia d1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.31; TmII: 0.31; TmIII: 0.33. Leg measurements: see Appendix A.

Male unknown.
