Phalangacris sotsote Hugel and Desutter-Grandcolas View in CoL , n. sp.

( Figs 1G View FIGURE 1 , 13C View FIGURE 13 , 14C, F, I View FIGURE 14 , 15C View FIGURE 15 , 16G–I View FIGURE 16 , Table 9)

Type locality. Seychelles, La Digue.

Type material. Holotype male. 29VII2010 Seychelles, La Digue, Nid d’Aigle, sous gros rochers, 29.vii.2010, S. Hugel leg. (2010SEY126), MNHN-EO-ENSIF12121.

Paratype. 1 male, same as holotype (2010SEY123), S. Hugel leg., coll.

Etymology. Species named after the Creole expression “sot sote”, meaning hopping.

Diagnosis. In addition to generic characters. Size large for the genus (BodyL ≥ 20 mm). Coloration: on the face ( Fig. 14C View FIGURE 14 ), a brown longitudinal line under each antennal pit, more marked ventrally, prolonged on the mandibles; a brown longitudinal median line ventrally, forked dorsally forming two paralongitudinal lines between antennal sockets. Male. FWs narrow and short for the genus, hardly reaching the middle of abdominal tergite 1; triangular in shape: narrowing toward apex; not covering sides of metanotum ( Fig. 14F 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; 4 spines between isa2 and isa3; 6–7 spines between isa3 and isa4; 19–21 above isa4. TIII outer serrulation: no spine before osa1; 2–3 spines between osa1 and osa2; 5–6 spines between osa2 and osa3; 8 spines between osa3 and osa4; 18–20 spines above osa4. Basitarsomeres III without dorsal inner spine in both male and female; with 4–5 dorsal outer spines, in addition to apical spines.

Coloration (from male holotype and paratype). Head yellow with dark brown patterns: on the face ( Fig. 14C View FIGURE 14 ), a brown longitudinal line under each antennal pit, more marked ventrally, prolonged on the mandibles; a brown longitudinal median line ventrally, forked dorsally forming two paralongitudinal lines between antennal sockets. Cheeks yellow with a dark posterior margin ( Fig. 14F View FIGURE 14 ). Maxillary palpi: articles 1 and 2 yellow; article 3—5 darker near apices and on carinae. Sockets white dorsally. Vertex and occiput with one longitudinal dark line behind each eye, with two subcircular black patterns between eyes; ocelli white. Scape yellow, darker dorsally and on anterior side; antennae brown; apical margins of basal articles yellowish, flagellum otherwise light brown. LL dark brown with a lighter anterior spot ( Fig. 14F View FIGURE 14 ); DD brown with light patterns, with two dark spots near anterior margin ( Fig. 13C View FIGURE 13 ). Abdomen spotted light and dark brown ( Fig. 13C View FIGURE 13 ); cerci light brown, darker after the middle. Legs yellow and dark brown, with dark rings and stripes: FI with three incomplete dark rings and dark lower margins; inner ventral carina dark brown; 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 two dark rings in filiform part, including one apical on the knee ( Fig. 15C View FIGURE 15 ); TIII as TI and TII, but with six dark rings; spurs yellow with dark basis and black tip. Basitarsomeres brown with lighter base; tarsomeres 2 light brown; tarsomeres 3 brown.
