Bioacoustics of Cardiodactylus reticulatus

Description. Male ( holotype ): Coloration of body yellowish with following ornament: head with a few small dark brown spots on face, dark brown area behind each eye, rather numerous dark brown spots on dorsum ( Fig. 6G ), small brown spots on scapes and palpi (including almost dark brown apex of apical segment of maxillary palpus), light brown proximal part of antennal flagellum, and brown middle and distal parts of this flagellum; pronotum with dark brown most part of lateral lobes and with numerous diverse brown and dark brown spots on dorsal disk ( Fig. 50B–C ); FWs brown (almost dark brown) with rather large spot near mirror and majority of veins and crossveins contrastingly whitish, M and R as well as stock of Sc reddish (R branches and crossveins between Sc and R whitish, and areas between these crossveins brown), a few veins in dorsal field brown and light brown, and small areas near stridulatory vein and at base of dorsal field as well as short humeral stripe in proximal part of this field from whitish to light brown ( Fig. 50D–E ); exposed part of hind wings dark brown with contrastingly yellowish and whitish venation; legs with rather numerous small dark brown spots on femora and coxae (and on pleurites near them), less numerous and larger dark brown spots on tibiae and tarsi (hind tibiae also with brown ventral part), and dark brown apical part of hind femora; abdomen with numerous dark brown and brown spots on tergites and supra-anal plate, small dark brown spots on cerci, light brown median band on subgenital plate, and brown lateral edges of this plate. Structure of body typical of Cardiodactylus ; rostrum between antennal cavities about 1.2 times as wide as scape; tegmina reaching abdominal apex, with mirror almost 2.2 times as long as wide and with Sc having 8–9 branches ( Fig. 50E ); hind wings significantly longer than FWs; fore tibiae with moderately large and oval outer tympanum and with rather short and slit-like inner tympanum. Male genitalia: Epiphallus moderately long, rather narrow, slightly asymmetrical, with almost parallel lateral edges ( Fig. 50H–K ), with high parts of dorsal ridges rather long (approximately equal to more distal part of epiphallus in length) as well as not contacted to each other and not curved aside, and with proximal corners of these parts angular in profile and separated from dorsoproximal lobes of epiphallus by rather deep notches. Female: General appearance similar to that of male, but FW dorsal field dark brown with 11 almost parallel light brown longitudinal veins moderately convex, and numerous (but not very dense) whitish crossveins ( Fig. 50F–G ); lateral field with Sc having 5–6 straight branches, sometimes with stock of R and M yellowish. Subgenital plate uniformly light. Ovipositor rather short (hind femur 1.45 times as long as ovipositor). Juvenile: Unknown. Measurements. Length in mm. Body: male 17, female 18–19; body with wings: male 23, female 23–25; pronL: male 2.4, female 2.5–2.7; FWL: male 12.5, female 13–14; FIIIL: male 14, female 14.5–16; ovipositor: 10–11. Habitat and life history traits. Cardiodactylus reticulatus was found in disturbed primary forest, on leaf or bush, at night. Behavior. Unknown.
