Description. Carapace yellow white, with a triangular dark band 
beginning one-third of the distance from the posterior median eyes to 
the cervical groove and which narrows from the anterior to form a 
blunt point at the cervical groove. It is indented anteriorly (Fig. 1). 
There is a black band around the carapace ending at the first coxa, 
continuing in the form of a very thin line with a black spot the 
width of the anterior median eyes in the center of the clypeus. The 
eye region is light. The legs have black spots, and the distal half of 
the tarsi are a very light brown. The size of the two specimens is 
different. The abdomen has two white spots slightly less than their 
diameter apart between the genital groove and spinnerets, with a 
pair of smaller white spots anterior to the spinnerets (Fig. 4). The 
dorsal abdominal pattern is similar to Theridion elli having a wavy 
white band which narrows posteriorly. It is bordered on both sides 
with a dark brown band (Fig. 1). Total length 1.84 mm. Carapace 
0.69 mm long, 0.59 mm wide. First femur, 1.22 mm; patella and
