Characterization.
Field Characteristics. Pupal case broadly oval, jet black (Figs 25, 26). Puparia with a small ring of fragmentary, striated white wax around true margin not reaching apparent margin (Fig. 26); dorsum of mature puparia with two pairs of longitudinal white wax bands, a narrow band along each dorsal submargin and a broader band on the submedial area on each side (Fig. 25).
Slide-mounted characters. TMS ending at apparent margin, lined with tubercles medially (Figs 176, 177); longitudinal molting suture lined with tubercles from TMS to level of mouthparts or head submargin; eyespots absent; Ce setae absent; T2 and T3 setae present, T3 setae arising well behind anterior margin of metanotum (Figs 176, 177); medial area with anterolateral depressions on abdomen insinuated to moderately developed, usually with a row of large tubercles along margins of T2/T3 suture and across anterior margin of each A1–A7 (Figs 176, 182), with pores and microsetae on each side of submedial area of head (4), T2 (2–3), T3 (0–3), A1 (2), A2 (0), A3 (2), A4 (0–2), A5 (2), A6 (0–2), A7 (2), and A8 (2); lateral areas of dorsal disc with variable number of large tubercles, with pores and microsetae between dorsal disc and submargin (Fig. 178); dorsal submargin with transverse double rows of small crescent-shaped imbrications (Fig. 178); deflexed submargin with a few pores on head and caudal abdomen (Figs 179, 185), with uniformly distributed granulations along its entire width (Figs 179, 185); marginal glandular teeth subquadragular with tips smoothly rounded, toothed or serrate; VO subrectangular, inset from posterior margin by about its own length or less (Figs 183–186); operculum cordate, its dorsal surface with longitudinal wavy ridges branching distally, with microspinulae across distal third to fourth; lingula concealed by operculum; VO ring subrectangular to subquadrate and narrow (Figs 183–186), with dorsal setae of A8 arising on its anterior margin, anterior to operculum anterior margin (Figs 183–186); with four membranous ventral sacs medially to bases of mesothoracic and metathoracic legs (Fig. 180), although in a few cases posterior pair is not visible; bases of caudal setae close together, at level of operculum lateral margins (Figs 183–186); venter smooth except for groups of spinulae medially to leg bases (Fig. 180).
Measurements (values of neotype in square brackets). Puparium length: 752 ± 81 [766]; maximum width (at level of TMS): 491 ± 52 [504]; length/maximum width: 1.5 ± 0.1 [1.5]; width at level of anterior margin of operculum: 271 ± 30 [310]; maximum width/width at anterior margin of operculum: 1.8 ± 0.1 [1.6]; deflexed submargin/body radius: 0.5 ± 0.1 [0.4]; Ce setae: absent [absent]; T2 setae: 5 [missing]; T3 setae: 5 [missing]; dorsal A8 setae: 10 [missing]; caudal setae: 45 ± 7 [38]; anterior marginal setae: 7 [not visible]; posterior marginal setae: 13 ± 0.9 [not visible]; ventral A8 setae:14 ± 3 [not visible]; VO ring length: 64 ± 5 [63]; VO ring width: 59 ± 7 [56]; VO ring length/width: 1.1 ± 0.1 [1.1]; caudal seta/VO ring length: 0.7 ± 0.1 [0.6]; caudal seta/operculum length: 1.2 ± 0.2 [1]; VO length: 42 ± 5 [40]; VO width: 40 ± 5 [44]; VO length/width: 1.1 ± 0.1 [0.9]; operculum length: 39 ± 5 [39]; operculum/VO length: 0.9 ± 0.05 [1] (see Table 1 for ranges).
Similar species. Wax pattern of mature puparium (Fig. 25) resembles that of T. eriogonum; however, in the latter species there is only one pair of dorsal longitudinal wax bands (Fig. 8). Slide mounted puparia are most similar to T. ceanothi and T. sierrae.
Diagnosis. See under T. ceanothi for a diagnosis from that species. It differs from T. sierrae by its more elongate puparium (Fig. 176) with maximum width at level of transverse arm of TMS [maximum width at level of A 2 in T. sierrae; Figs 201, 202], presence of distinct tubercles across anteromedial section of A1–A7 (Figs 176, 182), and presence of granulations on deflexed margin (Figs 179, 185) [both absent in T. sierrae; Figs 201, 202, 205, 206].
Remarks. The original description of T. ornata (Drews & Sampson 1958) did not include a type designation, number of type specimens and type depository were not indicated, and only a “Type locality” was given: “three miles east of Mentone, San Bernardino County, California. Collected October 3, 1953, by E.A. Drews.” No specimens matching these data were located in any major California collection nor among the portion of W.W. Sampson's collection that was donated to CSCA, and we believe that its type series is lost. To ensure the nomenclatorial stability of the name we consider it necessary to designate a neotype from among specimens from W.W. Sampson's ex collection collected at or near its type locality with the following label data: San Bernardino County, Mentone, on Eriodictyon trichocalyx, #9 [ex W.W. Sampson Coll, CSCA], which is here illustrated (Figs 176, 182, 183, 185) and measured (see under Measurements).
Drews & Sampson description of this species stated “(1958: 122) marginal band and entire median area with large, thick-walled wax pores…” The structures they referred to as pores are however just tubercles, sometimes appearing to be C-shaped (e. g., Figs 176, 182). In the key in Valencia & Evans (2024: 210) this species is treated as having three pairs of setae on mesothorax and two on metathorax, versus one pair in T. laingi. However, both species have one pair of T2 and T3 setae only, and a few microsetae (not always discernible from pores) on these segments.
Biology. Present mostly on lower surfaces of host leaves, and much more abundant in small plants than in older plants according to Drews & Sampson (1958).
Distribution. San Bernardino and Stanislaus Counties in California and Nevada.
