Karl coll. [CSCA]. Hosts. Rhamnaceae: Redberry (Rhamnus crocea, R. ilicifolia). Characterization. Field Characteristics. Puparium markedly oblanceolate, with medial area of dorsum depressed and pronounced caudal protuberance, black, with a narrow lateral ring of white wax around true margin (Figs 23, 24). Slide-mounted characters. TMS ending at apparent margin, lined with tubercles medially; longitudinal molting suture lined with tubercles from TMS to submargin (Figs 168 –170); eyespots absent; Ce setae absent; T2 and T3 setae present, T3 setae arising well behind anterior margin of metanotum; medial area of head and thorax devoid of tubercles (Figs 168 –170); medial area of abdomen of abdominal segments A1–A6 with large tubercles adjacent to anterior margins (Figs 168, 169); anterolateral depressions on abdomen insinuated, usually with pores and microsetae on each side of submedial area of head (4), T2 (2–3), T3 (2–3), A1 (2), A2 (0), A3 (2), A4 (0), A5 (2), A6 (0), A7 (2), and A8 (2); lateral areas of dorsal disc with large and small tubercles except for head, lacking pores or microsetae between dorsal disc and submargin; dorsal submargin with transverse double rows of tubercles turning into crescent-shaped imbrications towards apparent margin, not reaching it (Fig. 172); deflexed submargin lacking microsetae and pores, with a few small granulations distributed uniformly (Figs 173); marginal glandular teeth subquadragular with tips serrate (Figs 171, 173); VO subcordate, inset from posterior margin by about its own length to slightly more than its own length; operculum cordate, its dorsal surface with longitudinal wavy ridges branching distally, with microspinulae across distal third to fourth; lingula concealed by operculum; VO ring subquadrate, wide, slightly wider anteriorly (Figs 174, 175), with dorsal setae of A8 arising on anterior margin, anterior to anterior margin of operculum (Figs 174, 175); with two membranous ventral sacs medially to bases of mesothoracic legs (Fig. 171); bases of caudal setae close together, within level of operculum lateral margins (Fig. 169); venter smooth except for groups of spinulae medially to leg bases (Fig. 171). Measurements (values of neotype in square brackets). Puparium length: 667 ± 46 [696]; maximum width (at level of TMS): 384 ± 27 [392]; length/maximum width: 1.7 ± 0.1 [1.8]; width at level of anterior margin of operculum: 165 ± 20 [165]; maximum width/width at anterior margin of operculum: 2.3 ± 0.2 [2.4]; deflexed submargin/body radius: 0.5 ± 0.1 [0.5]; Ce setae: absent; T2 setae: 6 ± 1 [7]; T3 setae: 8 ± 2 [10]; dorsal A8 setae: 8 ± 1 [not visible]; caudal setae: 28 ± 5 [missing]; anterior marginal setae: 9 [not visible]; posterior marginal setae: 10 ± 3 [not visible]; ventral A8 setae: 15 [not visible]; VO ring length: 55 ± 3 [56]; VO ring width: 50 ± 5 [56]; VO ring length/width: 1.1 ± 0.1 [1]; caudal seta/VO ring length: 0.5 ± 0.2 [NA]; caudal seta/operculum length: 0.9 ± 0.4 [NA]; VO length: 35 ± 3 [40]; VO width: 36 ± 4 [44]; VO length/width: 1 ± 0.1 [0.9]; operculum length: 32 ± 3 [33]; operculum/VO length: 0.9 ± 0.1 [0.8] (see Table 1 for ranges). Similar species. Tetralicia lantanae in California, and T. granulata, T. pseudogranulata, and T. sampsoni in Mexico share an oblanceolate shape and dorsal disc extensively covered with large tubercles. Diagnosis. It can be recognized from all the species mentioned above (characters for other species in square brackets) by tubercle-shaped ornamentations on submedian area of A1–A6 present only across anterior margin (Figs 168, 169) [across both anterior and posterior areas to almost entire surface of A1–A6, Figs 134, 135, 137, 210, 211, 216]. Remarks. The original description of T. oblanceolata (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: "Silverado Canyon, Orange County, California. Collected at the upper end of the canyon road by E.A. Drews, December 19, 1953." 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, which we selected from among specimens collected at its type locality with the following data: Orange County, Silverado Canyon, on Rhamnus sp., i.1954 [ex W.W. Sampson Coll., CSCA]; the neotype is here illustrated (Figs 168, 170, 172, 174) and measured (see under Measurements). In the key in Valencia & Evans (2024: 211), this species is considered to lack T2 setae. However, all the specimens we examined do have T2 setal sockets (Figs 168 –170), and in several of these setae are not missing or broken off (see Table 1 for measurements). Biology. Found on underside of leaves in relatively few numbers, from 10 to 20 per leaf (Drews & Sampson 1958). Distribution. Common on its preferred host in Orange, Los Angeles, Riverside, San Bernardino, San Diego, Santa Clara, and Yolo Counties in California.
