Type material: Microneta llanoensis Gertsch & Davis 1936, 3 HOLOTYPE from Llano, Texas, Dec., 1934, L. Irby Davis (AMNH). EXAMINED.
Diagnosis: Males are diagnosed from all Agyneta by their large, squared dorsal and elongated ventral cymbial tubercles (Fig. 426), from A. bronx by their short lamella characteristica (Fig. 425), elongated in the latter (Fig. 432). Females are differentiated from all species by conspicuous divering copulatory ducts visible on the proximal part of scape (Fig. 429). Whereas in A. bronx the copulatory ducts are converging on the proximal part of scape (Fig. 436).
Description: Male: Total length 1.98; carapace length 0.87, width 0.73.
