Comments: MALE: COLOR: Carapace with a median longitudinal yellow band beginning at second eye row. Band slightly invaded by black pigment at level of third eye row, expanded slightly behind middle of carapace and straight from middle to posterior margin. Thoracic groove dark. A submarginal yellow band as wide as median extends from posterior lateral angles of carapace to anterior eye row. Eyes ringed with black; tuft of gray hairs between eyes of second row. Labium and endites yellow. Sternum yellow, with a thin median longitudinal black line and three small black spots on each side between coxae. Abdomen with a median light band tapering to a point at posterior end of abdomen; anteriorly the band includes a pair of longitudinal dark lines which extend posteriorly to about the middle of the abdomen where they unite and continue a short distance as a single line. Sides of abdomen becoming lighter ventrally. Venter yellow, with a pair of irregular black lines extending from the genital furrow posteriorly and approaching each other in the region of the spinnerets. Distal two-fifths of tibia I with a brush of jet black hairs; distal tip of metatarsus IV dark. All other leg segments yellow. FEMALE: COLOR: As in male except for absence of brush on tibia I.
Total Length: MALE: Total length, 7.50 mm. Carapace, 3.92 mm. long, 3.00 mm. wide. Sternum, 1.78 mm. long, 1.35 mm. wide. Abdomen, 3.57 mm. long. FEMALE: Total length, 8.07 mm. Carapace, 4.07 mm. long, 2.85 mm. wide. Sternum, 1.71 mm. long, 1.28 mm. wide. Abdomen, 4.00 mm. long.
Structural Features: MALE: STRUCTURE: First eye row moderately procurved. Anterior medians closer to anterior laterals than to each other and separated by a little less than their diameter. Eyes of third row separated by two and onehalf times their diameter. Sides of head moderately steep. Carapace almost horizontal to posterior end of thoracic furrow, after which there is an even slope to the posterior margin of the carapace. Spination as usual in the genus. Leg ratio: 4:1:2:3. Palpal organ with almost one-half of cymbium extending above alveolus. Details as figured. FEMALE: STRUCTURE: As in male. Epigynum with narrow lateral guides; details as figured. The median apophysis of this species is similar to that of Schizocosa duplex Chamberlin, and the distal division of the bulb has a very small horn. However, the brush of hairs present in the male of this species is lacking in S. duplex, and the female epigynum has much narrower lateral guides, with the division barely evident.
