JENNIFER M. BOSCO & ANGELA CHUANG (2018) A new species of grass spider, Agelenopsis
riechertii, from the Southwestern USA, with notes on its courtship behavior (Araneae: Agelenidae).
Zootaxa, 4442: 579–583.
We made changes in the description of a new Agelenopsis spider species, Agelenopsis riechertae. Firstly, we
declare the male holotype and a type repository to validate the species description, which was previously omitted.
The original Latin name has been feminized from Agelenopsis riechertii to Agelenopsis riechertae.
The holotype has been assigned to a male specimen, DMNS ZA. 38751. Three paratypes have been declared, one
male (DMNS ZA.38752), and two females (DMNS ZA.38753, DMNS ZA.38754), all collected with the holotype
at the Balmorhea location at 30.94° N, 103.79° W. All specimens have been lodged at the Denver Museum of
Nature & Science.
The species is renamed to Agelenopsis riechertae, which is latinized for a female, given that it is being named after
Dr. Susan Riechert.
“Agelenopsis lisa Gertsch, unpublished materials” should be removed from the taxonomic section.
The following images are omitted from the manuscript.

FIGURE 27. We recorded male A. riechertae on the webs of females with a Laser doppler vibrometer to document their court-
ship sequences, which involved waveforms of a) a web pulse; b) a period of abdomen waggling which are performed through-

out courtship prior to web flexing; c) and a series of web flexes which usually occur immediately after abdomen waggling.
