Bioacoustics of Brontostoma doughertyae

Description. Female (Figs. 47–48; 51–55). Dimensions (in mm) – Total length: 25.0–26.0; Head length: 3.6–4.2; head width: 3.0–3.2; interocular distance: 1.7–1.8; antennal segments: I: 3.1; II: 3.4; III: 1.7; IV: 1.0; V: 1.0; VI: 0.5; VII: 0.5; rostrum segments: I: 1.9–2.3; II: 1.3–1.7; III: 0.7. Thorax: pronotum: anterior lobe: length: 2.1–2.3; width: 4.8–5.3; posterior lobe: length: 2.6–2.7; width: 6.3–6.9. Fore legs: femur: 4.5–5.4; tibia: 4.8–5.6; tarsus: 1.6; middle legs: femur: 4.4–5.0; tibia: 5.0–5.5; tarsus: 1.8; hind legs: femur: 7.2–7.5; tibia: 7.9–8.5; tarsus: 2.1–2.3. Abdomen: length: 14.5–16.5; width: 9.5–10.3. Head, thorax, coxae, femora, and sternites black to brownish black; corium of hemelytra whitish to yellow whitish with red markings in basal and distal corial margins, or as large reddish lateral fasciae; apical portion of corium blackish as adjoining membrane; basal portion of veins in membrane yellowish (Figs. 47–48). Antennal segments I and II blackish; III brownish with yellowish apex; IV yellowish, apex brown; V and VI yellowish and VII brownish. Tibiae yellowish; fore pair with basal and half of distal portion blackish; middle pair with basal and one-third distal portion blackish; hind pair almost entirely yellowish, with only basal and distal portions blackish. Tarsal segments I and II brighter; III brownish. Connexivum partly yellowish in external portion or almost entirely darkened (Figs. 47–48). Integument almost complete glabrous and shiny. Antennal segments I and basal third of II glabrous; remainder with yellowish to brownish long and short fine hairs. Lateral portions of stridulatory sulcus, mesosternum, internal face, and apices of tibiae and tarsi with yellowish, fine, long and short hairs. First and third segments of rostrum with very sparse erect hairs. Head with short neck; interocular space somewhat prominent (Fig. 51); rostrum thick; antenna seven-segmented. Pronotum surface smooth; longitudinal sulcus well marked in the distal and proximal middle portions in anterior and posterior lobes respectively; interlobar sulcus well marked, sinuous, interrupted in central portion Scutellum triangular, prongs short. Anterior and median trochanters and femora with patches of short stiff hairs; anterior and median femora incrassate, armed with almost imperceptible tubercles (Figs. 52–53). Fore and mid tibiae dilated and pilose in apical portion with spongy fossae occupying little more than one-third of their length; hind tibiae with slight preapical dilation (Figs. 52–53). Hind leg simple, with tuft of hairs and setae at apex (Fig. 54). All tarsi well developed, hairy. Terminal segments as represented in Figure 55. Male (Figs. 49–50; 56–64). There are few differences between the male and female of this species. The objective ones are the absence of hairs in the first and basal part of the second antennal segments in the female, better developed eyes in the male (Fig. 56), and an abdomen that is somewhat larger in the female as observed in both other Ectrichodiinae and in particular Brontostoma spp. ( Dougherty 1995 ). Male genitalia remarks: Pygophore sub-pentagonal (Figs. 57–58). Parameres almost imperceptible in situ ; apices close in resting position (Figs. 57–58). Median portion of posterior process of pygophore short and subtriangular (Fig. 59). Parameres curved; apices truncate with tooth in inferior margin of rounded and somewhat dilated appearance (Figs. 60–61). Phallus simple (Figs. 62–63); phallosoma well sclerotized, specially in the margins; sinuous in anterior margin (Fig. 62); endosoma process united in median portion, subrectangular with middle third thinner (Fig. 62); support for phallosoma and gonopore process as in Figure 64.
