Diplospinula Siqueira & Souza-Dias, 2024 gen. nov.
Type species. Diplospinula serrana sp. nov.
Etymology. The name is a combination of the Latinized Greek word diplous (= double) and the Latin word spinula (= small spine). It refers to the presence of two small hook-shaped spines on the ninth male tergite.
Diagnosis. Diplospinula gen. nov. can be distinguished from other Gryllacridinae genera by the following combination of characters: both sexes apterous; stridulatory apparatus present laterally on the tergites II and III, two stridulatory pegs on each segment, first shorter; spurs of TI and TII shorter than tibia width; posterior margin of male tergite IX with pair of structures small, spine-shaped, apex slightly curved downward; subgenital plate without styli.
Description. Both sexes apterous ( Figs 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 ). Coloration. Body yellow ochre uniform, with slight variations in shades of yellow and brown ( Figs 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 ); ocelli whitish. Head. Face elongated, smooth ( Figs 3A, D View FIGURE 3 ). Lateral ocelli small, rounded, almost indistinct, median ocellus absent ( Figs 3A, D View FIGURE 3 ). Maxillary palpi article 4 slightly longer than 3, article 5 apex rounded ( Fig 2A View FIGURE 2 ); labial palpi article 5 dilated, apex rounded ( Fig. 2A View FIGURE 2 ). Pronotum. Pronotum disc subrectangular, glabrous ( Figs 1 View FIGURE 1 , 2 View FIGURE 2 ); lateral lobes with distinct furrow V-shaped ( Figs 1B View FIGURE 1 , 2A, B View FIGURE 2 ). Legs. Coxa I armed with dorsal spine ( Figs 1A, B View FIGURE 1 ; 2A, B View FIGURE 2 ). Spurs of TI and TII shorter than tibia width ( Figs 1A, B, D View FIGURE 1 ); TII with inner apical spine ( Figs 1B, D View FIGURE 1 ). FIII robust, ventrally armed with 1-7 spines on each face. TIII dorsally armed with 4-6 spines on each face; without pre-apical ventral spine; apical spurs: 3/3. Abdomen. Stridulatory apparatus on tergites II and III, two stridulatory rows on each segment, first shorter ( Figs 2A, B View FIGURE 2 , 3B, E View FIGURE 3 ). Cerci conical, covered with small setae ( Figs 3C, F View FIGURE 3 ). Male. IX tergite without longitudinal furrow or thinner area on dorsal region ( Fig. 3C View FIGURE 3 ); central area of posterior margin with small process, slightly projected forward; posterior margin laterally with pair of structures small, spine-shaped, apex slightly curved downward ( Fig. 3C View FIGURE 3 ). Subgenital plate without styli ( Fig. 3C View FIGURE 3 ). Female. Subgenital plate semicircular, base straight, posterior margin rounded, with setae ( Fig. 3F View FIGURE 3 ). Ovipositor as long as FIII, margins smooth, sharp ( Figs 1D View FIGURE 1 , 2B View FIGURE 2 ).
Distribution. This genus is recorded for the Atlantic Forest of the Serra dos Órgãos (Órgãos Mountain Range), a mountain range located in the state of Rio de Janeiro and part of the larger Serra do Mar Mountain Range.
