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 View FIGURES 425 – 431 ), from A. bronx by their short lamella characteristica ( Fig. 425 View FIGURES 425 – 431 ), elongated in the latter ( Fig. 432 View FIGURES 432 – 438 ). Females are differentiated from all species by conspicuous divering copulatory ducts visible on the proximal part of scape ( Fig. 429 View FIGURES 425 – 431 ). Whereas in A. bronx the copulatory ducts are converging on the proximal part of scape ( Fig. 436 View FIGURES 432 – 438 ).

Description: Male: Total length 1.98; carapace length 0.87, width 0.73.
