Diagnosis. This species can be recognized by the following combination of characters: pronotum and hemelytron brown with pale brown to whitish brown markings ( Fig. 1A ); middle and hind coxae whitish, fore- and middle femora mostly pale brown, hind femur mostly brown with large whitish band in apical half; segment I of hind tarsus shorter than segment II ( Fig. 4D ), setae on antennal segment II mostly adpressed, shorter than segment II width ( Fig. 4L ); genital capsule with narrow and short outgrowth apically, and with outgrowth near opening on right side ( Fig. 5C ), right paramere rounded basally ( Fig. 5D ), endosoma voluminous, with three elongate sclerites, one of them placed horizontally at base, second one placed vertically in the middle, and third one with teeth placed apically ( Fig. 5A, B ).

Description. Male. Body size 3.1–3.3. Coloration ( Fig. 1 ). Background coloration brown with pale brown to whitish brown markings; head whitish brown to pale brown with brown markings dorsally and laterally; antennal segments I–II yellow, segments III–IV brown to dark brown; labium pale brown; pronotum whitish brown to pale brown with brown markings; mesoscutum brown; scutellum whitish brown with anterior angles and medial stripe brown; pleura brown with whitish metathoracic scent gland evaporative area; hemelytron brown with marking on corium anteriorly, medially and along cuneus whitish, clavus basally and apically whitish; cuneus mostly reddish brown, whitish apically; forecoxae brown, middle and hind coxae whitish; fore- and middle femora pale brown with brown bands and basal and apical parts; hind femur mostly brown with large whitish band in apical half; tibiae mostly pale brown, dark brown at very base; tarsi pale brown; abdomen brown. Surface and vestiture. Setae on antenna, pleura, legs, and abdomen adpressed and mostly shorter than antennal segment II width ( Fig 4 K-M). Structure and measurements. Body ca. 2.6–3.1× as long as wide, ca. 3.0–3.2× as long as pronotum width; head ca. 1.3–1.7× as wide as long, in lateral view head as long as high; distance between buccula and pronotum as long as buccula length; antennal segment I ca. 1.1–1.3× as long as vertex, ca. 0.4–0.5× as long as head width; antennal segment II ca. 3.3–3.9× as long as segment I, ca. 1.6–1.7× as long as head width, ca. 0.9× as long as pronotum width, antennal segment III subequal to half of segment II, segment IV as long as segment III; labial segment III subequal to segment II, segment IV subequal to 2/3 of segment III; pronotum ca. 1.8–2.0× as wide as head, ca. 2.1–2.3× as wide as long; tarsal segment I slightly shorter than segment II ( Fig. 4D ). Genitalia. Genital capsule wider than long, with narrow and short outgrowth apically, and with outgrowth near opening on right side ( Fig. 5C ); right paramere rounded basally ( Fig. 5D ); phallotheca strongly sclerotized at base dorsally; endosoma voluminous, with three elongate sclerites, one of them placed horizontally at base, second one placed vertically in the middle, and third one minutely toothed placed apically ( Fig 4A, B ).

Female. Body size 3.5–3.6. Coloration ( Fig. 1A ). Similar to male, medial stripe on scutellum sometimes pale brown or very faint. Body ca. 2.9–3.0× as long as wide, ca. 3.2–3.4× as long as pronotum width; head ca. 1.4–1.6× as wide as long; antennal segment I ca. 1.0–1.2× as long as vertex, ca. 0.4–0.5× as long as head width; antennal segment II ca. 3.7–4.0× as long as segment I, ca. 1.6–1.8× as long as head width, ca. 0.9× as long as pronotum width, antennal segment III slightly longer than segment II, segment IV as long as segment III; labial segment III subequal to segment II, segment IV subequal to segment III; pronotum ca. 1.8–2.0× as wide as head, ca. 2.3× as wide as long. Genitalia. Dorsal labiate plate wider than long; sclerotized rings present, acute posteriorly, twice as long as wide, distance between rings 4× as long as sclerotized ring width; spermathecal gland placed in anterior half ( Fig. 6A ); posterior wall mostly sclerotized, with paired membranous areas at sides ( Fig. 6B ); vulva surrounded by paired rounded sclerites at sides, and single elongate sclerotized area posteriorly ( Fig. 6C ).

Distribution. Known from three localities in Queensland in the coastal area between Abbot Bay and Shoalwater Bay ( Fig. 1B ).

Etymology. This species is named after Mount Dryander, where the holotype was collected.
