Mictlana plana (Goodnight & Goodnight, 1973) n. comb.

Hoplobunus planus Goodnight & Goodnight, 1973: 88 . — Reddell 1981: 165. — Rambla & Juberthie 1994: 218. — Kury & Cokendolpher 2000: 155. — Kury 2003: 238. — Cruz-López & Francke 2017: 322. — Aguiñaga & Cruz-López 2019: 2.

MATERIAL EXAMINED. — Holotype. Mexico. ♂; San Luís Potosí: Aquismón, Cueva de San Nicolas, 10 Km SW Aquismón; 16.VII.1968; J. Fish leg; AMNH.

DIAGNOSIS. — Mictlana plana n. comb. can be differentiated from M. inops by the shape of lateral clear areas of scutum: these are small and rounded in M. plana n. comb., while they are large and digitiform in M. Inops .

REMARKS

During the revision of stygnopsid types deposited at the AMNH, penises of some of them were found lost. Even though the penis of Hoplobunus planus is quite damaged, penial morphology was clear, with two pairs of short MS C and A on lateral margins, remarkably similar to those on M. inops . Also, both lobes on prosoma are present, but in M. plana n. comb the middle one is barely noticeable.
