Diagnosis: Recognized from other species of the Nearctic erosa group by the following combination of characters:(1) shallow lateral notch, (2) posterior pronotal angle conspicuous and right, (3) very short and blunt frontal process, and (4) flattened anterior pronotal disk that is usually very smooth overall and without raised tubercles along the posterior margin.
Description: Male: Small to medium, total length ~6.59–7.15 mm, width across lateral angles of pronotum: ~2.38–2.66 mm. STRUCTURE: HEAD (Fig. 14A,C,D): distiflagellomere of male shorter than pedicel + basiflagellomere. THORAX (Figs 14A,C,D, 20L): thoracic surface matte; anterior pronotal disk without elongated setaceous granulation; posterior pronotal disk punctate; area between lateral pronotal notch and longitudinal carina of the posterior pronotal lobe usually with a small granulation patch; longitudinal carina without prominent tubercle; lateral margin of anterior pronotal lobe not keeled and inconspicuous; lateral notch shallow; lateral margin of pronotum from lateral notch to lateral angle smooth or with light crenulation; lateral angle small and obtuse; posterior angle prominent and right; lateral surface of forefemur smooth or sparsely granulated; lateral surface of thorax smooth or sparsely granulated; forewing membrane brown, cloudy, never hyaline. ABDOMEN (Fig. 14B): posterior corners of connexiva of abdominal segments 2–4 inconspicuous/subtle; lateral margins of connexiva of abdominal segments 4–5 convex; lateral margins of connexiva of abdominal segments 3–6 with or without fine granulation; connexivum of abdominal segment 5 less than twice as wide as connexivum of abdominal segment 4; connexivum of abdominal segment 6 rhomboidal, anterior and posterior margin roughly the same width. COLORATION (Figs 14A–D): variable; anterior pronotal lobe usually with dark marking; forefemur pale, never darkened; corium with a conspicuous transverse band (usually pink or purple in color); body overall usually pale yellow or greenish with dark brown or black markings. Female: Small to medium, total length: ~6.89–7.94 mm, width across lateral angles of pronotum: ~2.47–2.88 mm. COLORATION (Figs 14A,B,E): very similar to that of males.
Etymology: Named for its resemblance to P. borica Evans, a species native to the Colorado Plateau region of the United States.
Biology: Phymata paraborica has been collected from Eriogonum fasciculatum Benth. (Polygonaceae) and Adenostoma Hook. & Arn. (Rosaceae) in scrublands and chaparral habitats.
Distribution: This species is found along the Transverse Ranges of southern California.
Discussion and identification remarks: This species is sympatric with P. pacifica and can be found on the same host plants (i.e., E. fasciculatum). Phymata paraborica sp. nov. has a more diffuse granulation patch, flatter lateral margin of the anterior pronotal lobe, shallower lateral notch, obtuse or right lateral angle (compare with acute lateral angle of P. pacifica) and is overall much darker than P. pacifica. These additional characteristics help separate P. paraborica sp. nov. from other Californian taxa: (1) the small to medium size, (2) lateral margin of anterior pronotal lobe smooth (compare with crenulated margin of P. luteomarginata), (3) both sexes often with blackened head and pronotum (never black in P. luteomarginata females), and (4) brown forewing membrane (compare with hyaline membrane of P. luteomarginata or P. metcalfi).
Type information: The holotype and allotype of this new species have been deposited in the University of California Riverside Entomology Research Museum, Riverside, CA, USA. In total, 79 specimens, comprising 39 adult males and 40 adult females were designated as types.
