Diagnosis.

Recognized among species of Schizoptera (Schizoptera) by fairly uniformly dark brown coloration with contrasting yellow posterior pronotal margin and humeral angle, whitish membrane with apical ½ suffused, and contrasting yellow and brown legs, large posterior process on sternum 6, and subgenital plate with medium-sized finger-shaped lateral process pointing laterad and with distinctive border of stout setae along right margin of subgenital plate (Figure 9G).

Description.

Male (Figure 8): macropterous, length: 1.51-1.67 mm; body ovate. Coloration (Figure 8): general coloration dark brown, posterior margin of pronotum, humeral angles, scutellar margin, and marking distal to apex of clavus yellow, costal and posterior claval margins yellowish brown, membrane white with apical 1/2 slightly suffused, legs with coxae and femora brown, trochanters yellow, tibiae brown proximally and yellow distally, (Figure 8). Surface and vestiture: long and moderately dense on head, pronotum, and forewing veins. Structure: Head: triangular in frontal view, distinctly wider than high (Figure 8), synthlipsis slightly more than twice width of eye. Thorax: posterior pronotal margin almost straight, very weakly concave medially, dc1 of similar width throughout, almost as wide as 3. Abdomen: sternum 6 with large posterior process, subgenital plate with medium-sized finger-shaped lateral process pointing laterad and with distinctive border of stout setae along right margin of subgenital plate (Figure 9G). Genitalia (Figure 9 G–I): right conjunctival appendage with two spines, longer apically, beset with small tubercles, left conjunctival with two lobes (Figure 9I), right paramere long and slender, with gently curving apex (Figure 9H), left paramere roughly triangular with broad apex (Figure 9I,H), vesica looping, very slender, with more than four coils (Figure 9H).

Female: Unknown.

Etymology.

Named in honor of Dr. Thomas Henry on the occasion of his 70th birthday and in recognition of his outstanding contributions to heteropterology. We also thank Tom for advancing our understanding of the little-studied Schizopteridae in the United States by keeping his dedicated eye open for these tiny bugs and publishing updated distribution records. A noun in genitive case.

Distribution.

Known from Tamaulipas and Veracruz in Mexico and Cameron County in Texas in the U.S.

Notes.

This species is unique among Schizoptera in the U.S. in having brown and yellow contrasting legs, in addition to the distinctive features of the male abdomen and genitalia.
