description: Neduba longiplutea Cole, Weissman, & Lightfoot, sp. n.
Fig. 9. (distribution), Fig. 14 (male and female habitus, calling song, male and female terminalia, karyotype), Plate 4E (male calling song), Plate 6J (male ventral sclerite), Plate 9F (male titillators), Plate 11E (female subgenital plate).
Common name. Trinity Alps Shieldback.
History of recognition. Apparently confused with N. convexa, 1 male and 1 female from CA, Trinity Co., Big Flat, 15-VIII-1960, PH Benson (Rentz & Birchim 1968).
Type material. HOLOTYPE MALE: USA, CA, Humboldt Co., East Fork Campground, 5.2 mi. W of Willow Creek, Six Rivers National Forest, 40.90582N, 123.7068W, 471 m, 6-VIII-2014, JA Cole, DB Weissman, JAC000002182 [specimen barcode], DNA125 [tissue], SING0458 [DNA extraction], JCT14-2 [karyotype], deposited at CAS, Entomology type #19711.
PARATYPES (n = 10): 5♁, 2♀, same data as holotype, LACM; 2♁, same data as holotype, CAS; 1♁, same data as holotype, JAC.
Measurements. (mm, ♁n = 8, ♀ n = 2) Hind femur ♁18.35–20.00, ♀ 21.41–21.61, pronotum total length ♁8.17– 9.30, ♀ 7.60–7.78, prozona length ♁2.92–3.75, ♀ 3.93–3.96, metazona dorsal length ♁4.73–5.69, ♀ 3.64–3.85, pronotum constriction width ♁1.96–2.90, ♀ 2.21–2.51, metazona dorsal width ♁5.90–6.36, ♀ 5.20–5.40, head width ♁4.08– 4.30, ♀ 4.45–4.81, ovipositor length ♀ 15.68–16.45.
Distribution. Trinity Alps in the North Coast Ranges of California.
Habitat. Forest understory, on ferns, leaf litter, and occasionally arboreal. Some CSCA specimen labels indicate range grass.
Seasonal occurrence. Midsummer through fall, from July (19-VII-1934, EC VanDyke, CAS) to October (17- X-1995, Spadoni, CSCA). Nymphs from May through July.
Stridulatory file. (n = 4) length 3.4–3.9 mm, 114–125 teeth, tooth density 33.7 ± 3.0 (31.0–36.8) teeth/mm.
Song. (n = 4). PTR 2.7 ± 0.3 s- 1, PTF 14.4 ± 2.7 kHz, indistinguishable from topotype N. convexa.
Karyotype. (n = 4) 2n♁ = 26 (2m + 22t + XtYt). T14-25, S14-65, paratopotype.
Recognition. Male genitalia unique: the lateral process is as long or longer than the short, thick shaft. Female subgenital plate longer than wide and has a bifurcate apex. The subgenital plate of N. convexa has similar proportions but the apex is usually entire, rarely bifurcate.
Etymology. l. longi long + plutea barrier, screen, low wall, parapet. Descriptive of the long lateral process of the male ventral sclerite.
Notes. This species replaces N. convexa to the west. Populations may be large and widespread, judging from an 80 km acoustic transect through Humboldt and Trinity Counties, California (JAC and DBW, pers. obs.) and from the number of nymphs in museum collections. The song is identical to that of N. convexa. Color patterns are variable and beautifully match the complex background of the forests of the Trinity Alps.
