Description

Both sexes. Head elongated dome-shaped ( Figure 4a View Figure 4 ), lateral margins of preantennal area convex, frons rounded. Marginal carina narrow, much displaced and widened at osculum. Ventral anterior plate small, roughly oval. Head chaetotaxy as in Figure 4a View Figure 4 . Preantennal nodi small, not bulging. Pre-ocular nodi large, post-ocular nodi moderate. Marginal temporal carina with very irregular median margin. Gular plate lanceolate. Thoracic and abdominal segments as in Figure 3a–b View Figure 3 . Head and thorax medium brown, darker at head carinae, gular plate, and area anterior to antennal socket; sternal and subgenital plates and antero-lateral section of tergopleurites medium brown, posterior and median sections of tergopleurites pale, giving a striped appearance; pigmentation of abdomen darker in female than in male.

Male. Thoracic and abdominal chaetotaxy as in Figure 3a View Figure 3 ; ss absent from tergopleurite V; tps absent from tergopleurites II–VII; aps present on tergopleurites VI–VII; ps present on segment III. Basal apodeme narrowing anteriorly ( Figure 4b View Figure 4 ). Proximal mesosome long, broad, roughly trapezoidal ( Figure 4c View Figure 4 ). Mesosomal lobes unlike any other in Brueelia , with slender lateral thickenings, no rugose area, and 1 lateral pmes microseta on each side. Gonopore wide, flattened crescent-shaped with antero-lateral projections on each side; median section of gonopore slightly rugose. Penile arms minute, not reaching distal margin of mesosome. Parameres short, not elongated distally, pst1–2 as in Figure 4d View Figure 4 . Measurements ex Chondestes grammacus strigatus (n = 2): TL = 1.19–1.42; HL = 0.32–0.35; HW = 0.24–0.26; PRW = 0.15–0.16; PTW = 0.22–0.25; AW = 0.30–0.33. Measurements ex Ch. g. grammacus (n = 6): TL = 1.36–1.63; HL = 0.34–0.37; HW = 0.24–0.26; PRW = 0.15–0.17; PTW = 0.23–0.25; AW = 0.32–0.41.

Female. Thoracic and abdominal chaetotaxy as in Figure 3b View Figure 3 ; ps absent on segment III. Lateral margins of proximal subgenital plate more or less parallel ( Figure 4e View Figure 4 ), narrow connection to cross-piece. Vulval margin gently rounded ( Figure 4e View Figure 4 ), with 3 short, slender vms and 3–4 short, thorn-like vss on each side; 4–5 short, slender vos on each side of subgenital plate; distal 1 vos median to vss. Measurements ex Chondestes grammacus strigatus (n = 5): TL = 1.41–1.63; HL = 0.34–0.38; HW = 0.25–0.28; PRW = 0.16–0.18; PTW = 0.24–0.27; AW = 0.32–0.41. Measurements ex Ch. g. grammacus (n = 6): TL = 1.59–1.73; HL = 0.37–0.41; HW = 0.27–0.30; PRW = 0.17–0.19; PTW = 0.26–0.29; AW = 0.38–0.41.

Material examined

Ex Chondestes grammacus (subspecies unknown). 1♂, 1♀, 25 December 1935, EWS ( UMSP) .

Ex Chondestes grammacus grammacus . 4♂, 4♀, Red River , near Idabel, McCurtain County, Oklahoma, United States, 13 April 1958, G .M. Sutton, GMS-13,566 (PIPeR); 2♂, 2♀, same data ( NHML) .

Ex Chondestes grammacus strigatus . 2♂, 4♀, North Skull Valley , Tooele County, Utah, United States, 11 June 1964, E . & E. Branch, 5360, one slide PIPeR #126 (PIPeR); 1♀, Dugway Area , Tooele County, Utah, United States, May-Jun . 1966, E. & E. Branch (PIPeR). Remarks

Carriker’s (1902) original illustration appears to be drawn from an individual with a laterally compressed head, which results in the differences in head shape between his illustrations and ours.
