Type locality California , United States . Other hosts Spizella passerina passerina ( Bechstein 1798 ) – chipping sparrow. Diagnosis Brueelia cassiopeia sp. nov. is most similar to B. angustifrons ( Carriker 1902 ) and B. hesperides sp. nov. , with which it shares the following characters: tps absent from male tergopleurite VII ( Figures 3a , 5a , 13a ); aps present on male tergopleurites VI–VII ( Figures 3a , 5a , 13a ); ps absent from female abdominal segment III ( Figures 3b , 5b , 13b ). Brueelia cassiopeia is more similar to B. hesperides , with which it shares the following characters not found in B. angustifrons : ps absent from male abdominal segment III in B. cassiopeia ( Figure 13a ) and B. hesperides ( Figure 5a ), but present in B. angustifrons ( Figure 3a ); gonopore with antero-lateral extensions in B. angustifrons ( Figure 4c ), but without such extensions in the other two species ( Figures 6c and 14c ); rugose area present on mesosome in B. hesperides ( Figure 6c ) and B. cassiopeia ( Figure 14c ), but absent in B. angustifrons ( Figure 4c ). Brueelia cassiopeia can be separated from B. hesperides by the following characters: ss present on male tergopleurite V in B. cassiopeia ( Figure 13a ), but absent in B. hesperides ( Figure 5a ); proximal mesosome rounded in B. cassiopeia ( Figure 14c ), but flat in B. hesperides ( Figure 6c ); parameres elongated in B. hesperides ( Figure 6d ), but short in B. cassiopeia ( Figure 14d ); gonopore roughly rectangular with shallowly concave posterior margin in B. cassiopeia ( Figure 14c ), but broadly crescent-shaped, with deeply concave posterior margin in B. hesperides ( Figure 6c ). Description Both sexes. Head elongated drop-shaped ( Figure 14a ), lateral margins of preantennal head flat to slightly convex, in some specimens longer than illustrated, and with distal section slightly concave, frons flat to slightly concave. Marginal carina slender, deeply displaced and widened at osculum. Ventral anterior plate elongated. Head chaetotaxy as in Figure 14a . Preantennal nodi slender, not bulging. Pre- and postocular nodi moderate. Marginal temporal carina with irregular median margin. Gular plate lanceolate. Thoracic and abdominal segments as in Figure 13a–b . Base pigmentation pale brown; marginal and marginal temporal carinae, margins of antennal sockets, proepimera, metepisterna, and lateral margins of tergopleurites dark brown; sternal and subgenital plates and lateral section of tergopleurites medium brown. All pigmentation darker in female than in male. Male. Thoracic and abdominal chaetotaxy as in Figure 13a ; ss present on tergopleurite V; tps absent on tergopleurites II–VII; aps present on tergopleurites VI–VII; ps absent on abdominal segment III. Basal apodeme narrowing slightly anteriorly ( Figure 14b ). Proximal mesosome elongated, rounded, lateral margins concave ( Figure 14c ). Mesosomal lobes wide, rugose area extensive; 2 pmes sensilla on each side of gonopore. Gonopore broad, roughly rectangular, distal margin shallowly concave. Penile arms short, not reaching distal margin of mesosome. Parameres broad, not elongated, pst1–2 as in Figure 14d .

(a) male head, dorsal and ventral views; (b) male genitalia, dorsal view (C) male mesosome, ventral view; (d) male paramere, dorsal view; (e) female subgenital plate and vulval margin, ventral view. Female. Thoracic and abdominal chaetotaxy as in Figure 13b ; ss absent on abdominal segment III. Lateral margins of proximal subgenital plate concave to roughly parallel ( Figure 14e ), with narrow connection to cross-piece. Vulval margin gently rounded to slightly flattened medianly ( Figure 14e ), with 4–5 short, slender vms and 3–4 short, thornlike vss on each side; 3–4 short, slender vos on each side of subgenital plate; distal 1 vos median to vss . Measurements ex Spizella passerina arizonae (n = 16): TL = 1.63–1.79 (1.71); HL = 0.37–0.40 (0.38); HW = 0.25–0.27 (0.26); PRW = 0.16–0.17 (0.17); PTW = 0.25–0.27 (0.26); AW = 0.3–0.38 (0.35). Measurements ex S. p. passerina (n = 6 except TL and AW where n = 5): TL = 1.53–1.73; HL = 0.36–0.38; HW = 0.25–0.26; PRW = 0.15–0.17; PTW = 0.22–0.26; AW = 0.31–0.39. Etymology Brueelia cassiopeia is named after Queen Cassiopeia of Ethiopia , who was considered very beautiful, an attribute that applies equally well to the host of B. cassiopeia sp. nov. , as well as to the louse itself.
