Characterization.

Field characteristics. Pupal case oval with posterior end truncate, shiny black, surrounded by a fringe of amorphous white wax extending out from true margin up to or slightly beyond apparent margin ( Figs 2, 3 View FIGURES 1–4 ).

Slide-mounted characters. TMS reaching submargin but not extending over it, not reaching apparent margin, not lined with tubercles ( Figs 36 View FIGURE 36 , 38 View FIGURES 37–42 ); longitudinal molting suture lined with tubercles from T2/T3 suture to head submargin; eyespots absent; Ce setae absent; T2 and T3 setae present, T3 setae arising at anterior margin of metanotum; medial area with depressions lacking granulations on each side of head (two), T2 (three) and T3 (one), and abdominal segments (one) ( Figs 36 View FIGURE 36 , 37 View FIGURES 37–42 ); with pores and porettes on each side of submedial area of head (2–4), T2 (1–2), T3 (0–1), A1 (0–1), A2 (0–1), A3 (0–2), A4 (0–2), A5 (1–3), A6 (1–4 single pores), A7 (1), and A8 (1–2); dorsal disc smooth, with anterior margin of A1–A7 sclerotized ( Fig. 36 View FIGURE 36 ); with pairs of pores and porettes along sides of dorsal disc ( Figs 37, 38 View FIGURES 37–42 ); dorsal submargin lacking imbrications or granulations ( Fig. 38 View FIGURES 37–42 ); deflexed submargin with a row of pores and transverse rows of small granulations usually arranged in 1–3 compact clusters across about half to two thirds of its width ( Fig. 40 View FIGURES 37–42 ); marginal glandular teeth subquadrangular with tips bidentate; VO cordate, inset from posterior margin by about its own length; operculum cordate, its dorsal surface with a few longitudinal ridges and with microspinulae across distal third to fourth; lingula concealed by operculum; VO ring very narrow around lateral and posterior sections of VO, with anterior portion wide and rectangular, separated from remainder of ring, and with longitudinal crests ( Fig. 41 View FIGURES 37–42 ), with dorsal setae of A8 arising from sides anterior to anterior margin of operculum ( Fig. 41 View FIGURES 37–42 ); bases of caudal setae close together, within level of operculum lateral margins ( Fig. 42 View FIGURES 37–42 ); with two membranous ventral sacs medially to bases of mesothoracic legs ( Fig. 39 View FIGURES 37–42 ); tegument of venter smooth except for groups of strong spines medially to legs ( Fig. 39 View FIGURES 37–42 ).

Measurements (values of neotype in square brackets). Puparium length: 880 ± 92 [929]; maximum width (at level of A1): 641 ± 67 [669]; length/maximum width: 1.4 ± 0.05 [1.4]; width at level of anterior margin of operculum: 377 ± 60 [393]; maximum width/width at anterior margin of operculum: 1.7 ± 0.1 [1.7]; deflexed submargin/body radius: 0.4 ± 0.03 [0.4]; Ce setae: absent; T2 setae: 16 ± 4 [11]; T3 setae: 11 [11]; dorsal A8 setae: 15 ± 2 [16]; caudal setae 14 ± 1 [missing]; anterior marginal setae [not visible]: 9; posterior marginal setae: 18 ± 7 [not visible]; ventral A8 setae: 15 ± 1 [missing]; VO ring length: 67 ± 6 [70]; VO ring width: 63 ± 7 [63]; VO ring length/width: 1.1 ± 0.1 [1.1]; caudal seta/VO ring length: 0.2 ± 0.004 [NA]; caudal seta/operculum length: 0.4 ± 0.1 [NA]; VO length: 40 ± 4 [39]; VO width: 41 ± 6 [38]; VO length/width: 1 ± 0.1 [1]; operculum length: 33 ± 3 [30]; operculum/VO length: 0.8 ± 0.1 [0.8] (see Table 1 View TABLE 1 for ranges).

Similar species. It shares the combination of marked abdominal depressions, absence of pores along lateral margin of dorsal disc, submedian area of thorax smooth, and deflexed submargin with compact groups of small granulations arranged in transverse rows with Tetralicia nigrans , which is polyphagous and can also be found on Arctostaphylos .

Diagnosis. Puparium shape with posterior end truncate ( Figs 36 View FIGURE 36 , 41, 42 View FIGURES 37–42 ) is unique among species of this genus in California; it further differs from T. nigrans (characters for T. nigrans in square brackets) by: narrow lateral ring of amorphous wax visible dorsally ( Figs 2, 3 View FIGURES 1–4 ) [not visible dorsally; Fig. 21 View FIGURES 21–24 ]; lateral area of dorsal disc smooth ( Figs 36–38 View FIGURE 36 View FIGURES 37–42 ) [with small tubercles; Figs 161, 165 View FIGURES 161–167 ]; dorsal submargin smooth ( Fig. 38 View FIGURES 37–42 ) [with small tubercles; Fig. 162 View FIGURES 161–167 ]; deflexed submargin with 1–3 compact clusters of small granulations arranged in transverse rows across about half to two thirds of its width ( Fig. 40 View FIGURES 37–42 ) [with 7–9 compact clusters of small granulations arranged in transverse rows extending for about three quarters of its width; Fig. 164 View FIGURES 161–167 ]; VO cordate ( Figs 36 View FIGURE 36 , 41 View FIGURES 37–42 ) [subcordate; Figs 166, 167 View FIGURES 161–167 ]; subcordate VO ring closed anteriorly and with anterior portion separated from remainder of ring and sculpted with crests ( Figs 36 View FIGURE 36 , 41 View FIGURES 37–42 ) [cordate, open anteriorly, not separated, lacking crests; Figs 166, 167 View FIGURES 161–167 ]; venter with groups of strong spines medially to legs ( Fig. 39 View FIGURES 37–42 ) [with groups of spinulae medially to legs; Fig. 163 View FIGURES 161–167 ]; and dorsal setae short and hairlike [dorsal setae longer and ribbon-like; see table 1]

Remarks. The original description of T. acaudata ( Drews & Sampson 1958) did not include a type designation, number of type specimens and type depository were not indicated, and only a 'Type locality' ('Mill Creek Canyon Road (400 feet), San Bernardino County, California. Collected on December 21, 1953 by E.A. Drews.') was given. 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; therefore, we believe that its type specimen (s) is (are) lost. To ensure the nomenclatorial stability of the name we consider it necessary to designate a neotype, selected from specimens collected at its type locality with the following data: San Bernardino County, Mountain Home Village, Mill Creek Canyon, 1,220 m a.s.l., on manzanita, 21.iii.1986, R.J. Gill coll. [CSCA], which is here illustrated ( Figs 36–41 View FIGURE 36 View FIGURES 37–42 ) and measured (see under Measurements).

Drews & Sampson (1958) characterized this species as having 'the lateral margin with a narrow translucent band behind the marginal teeth.' However, this 'band' is most likely merely an artifact in their photographed specimen caused by the contrast between the folded deflexed margin (darker) and the thinner (lighter) adjacent medial area comprising only ventral and dorsal tegument.

Biology. Drews & Sampson (1958) found population density to be very low, but the species was found again in higher numbers at its type locality in 1986.

Distribution. Apparently occurs throughout California on manzanita; we have records from Butte, Contra Costa, Colusa, El Dorado, Fresno, Kern, Lake, Marin, Mendocino, Nevada, Riverside, and San Bernardino Counties. Carapia-Ruiz & Sánchez-Flores (2018) listed this species from Mexico without providing locality or host, perhaps referring to the records of Aleuropleurocelus aff acaudatus by Sánchez-Flores et al. (2015, 2016) on Persea americana . Since no images or descriptions were provided in those studies, we are unable to confirm their identifications and possible presence in Mexico.
