Molecular sampling. LDG 371 ( Warren et al. 2019)

Etymology. Species named after the Creole expression “fer le gro”, meaning “showing off”, in relation to the large size of the cricket. Noun in apposition.

Diagnosis. In addition to generic characters. Size large for the genus (Body L ≥ 20 mm). Coloration: on the face ( Fig. 14B View FIGURE 14 ), a faint brown longitudinal line under each antennal pit, prolonged on the mandibles; a brown, faint longitudinal median line, fading near preclypeus; a brown faint longitudinal line below the eyes. Male FW large for the genus, exceeding the middle of abdominal tergite 1; weakly narrowing toward apex ( Fig. 14H View FIGURE 14 ); covering sides of metanotum ( Fig. 14E View FIGURE 14 )

Description. In addition to the characters of the genus:

Fastigium with small black tubercle posterior to median ocellus. TIII inner serrulation: no spine before isa1; no spine between isa1 and isa2; 3–5 spines between isa2 and isa3, in both male and female; 4–6 spines between isa3 and isa4; 23–24 in males, 15–19 in females, above isa4. TIII outer serrulation: no spine before osa 1 in both male and female; 2–3 spines in males and females, between osa1 and osa2; 5–6 spines in males and females, between osa2 and osa3; 7 spines in males and females, between osa3 and osa4; 18–21 spines in male, 15–17 spines in female, above osa4. Basitarsomeres III without dorsal inner spine in both male and female; with 7 in male, 3–5 in female, dorsal outer spines, in addition to apical spines.

Coloration (from male holotype and female allotype). Head light brown with dark brown patterns ( Fig 14B, E View FIGURE 14 ): on the face ( Fig. 14B View FIGURE 14 ), a faint brown longitudinal line under each antennal pit, prolonged on the mandibles; a brown, faint longitudinal median line, fading near preclypeus; a brown faint longitudinal line below the eyes. Cheeks brown in posterior half ( Fig. 14E View FIGURE 14 ). Maxillary palpi: articles 1 and 2 light brown; article 3–5 darker near apices. Sockets white dorsally. Vertex and occiput with four weakly distinct longitudinal dark lines. Fastigium brown between ocelli; ocelli white. Scapes yellow with black spots on inner side; antennae brown; apical margins of basal articles yellowish, flagellum otherwise light brown. LL brown with a dark pattern on posterior margin and lighter anterior margin ( Fig. 14E View FIGURE 14 ); DD brown with light patterns ( Fig. 13B View FIGURE 13 ). Abdomen spotted light and dark brown ( Fig. 13B View FIGURE 13 ); cerci light brown with darker apex. Legs light and dark brown, with dark rings and stripes: FI with three incomplete dark rings and dark lower margins; TI brown with two small yellow rings, one median and one below the knee; FII as FI; TII as TI; FIII striated with dark brown on outer side and with three dark rings in filiform part, including one apical on the knee ( Fig. 15B View FIGURE 15 ); TIII as TI and TII, but with five dark rings; spurs yellow with black tip. Basitarsomeres brown with lighter base; tarsomeres 2 light brown; tarsomeres 3 brown.

Male. FW in males exceeding the middle of abdominal tergite 1 ( Fig. 14H View FIGURE 14 ).; weakly narrowing toward apex ( Fig. 14H View FIGURE 14 ); covering sides of metanotum ( Fig. 14E View FIGURE 14 ).

Male genitalia. As on figure 16D–F.

Female. Ovipositor straight, shorter than FIII, without terminal enlargement ( Fig. 15D View FIGURE 15 ).

Female genitalia. Copulatory papilla sclerotized, not forming a closed chamber ( Fig. 15E View FIGURE 15 ).
