REMARK
The most informative characters given by Saussure (1878) to separate Lerneca inalata (Saussure, 1874) from L. fuscipennis (Saussure, 1878) are the shape of the pronotum (trapezoidal, twice as wide as long, against more quadrangular in L. fuscipennis), the shape of the FWs (very wide, against little widened in L. fuscipennis), the shape of the stridulatory file (transverse and straight, against short and oblique in L. fuscipennis) and the slender shape of the legs. These characters are similarly well-contrasted between L. inalata inalata and Lerneca mitarakensis n. sp. (see Figs 13, 14). All the subspecies recently described in L. inalata differ from the description given by Saussure for pronotum, FW and file shapes, as shown by figures in original papers (Gorochov 2007, 2014; Lima et al. 2016). The taxonomic status and relationships of these taxa will have to be reconsidered with the analysis of the type of L. inalata, and through molecular studies
TYPE MATERIAL. — Holotype by original designation. Suriname • 1 ♂ (ZMUH, not examined).
MATERIAL EXAMINED. — French Guiana • 1 ♂; Monts Tumuc-Humac, Massif du Mitaraka, Savane roche; 54.4347 O 2.2387 N; alt. 390 m; 23.II.-10.III.2015; F. Legendre & S. Hugel leg.; fn. SH206, de nuit; MNHN • 1 ♂; Roche de Kourou; MNHN.
Venezuela • 3 ♂ 9 ♀, identified Diplacustes varipes Walker, 1869 by A. Finot, ex coll. Finot; MNHN.
DIAGNOSIS. — See Saussure (1874) and Saussure (1878) for general morphology and coloration, and Desutter-Grandcolas (1992a) for characters of male and female genitalia.
HABITAT. — During the Mitaraka expedition, L. inalata has been found de nuit in bedrock grown savannas, i.e., in dryer and more open areas than the surrounding forest.
COMPLEMENT TO DESCRIPTION
General morphology
TIII serrulation as on Table 9. HWs longer than FWs in both males and females by 4-5 mm.
Male
Stridulatory file with 175 – 200 teeth (see Table 10).
Male genitalia
As in Desutter-Grandcolas (1992a, figures 28-29) and on Fig. 15 E-G.
Female (after specimens from Venezuela)
Ovipositor straight, shorter than FIII and TIII. Subgenital plate short and transverse; distal margin almost straight.
Female genitalia
Copulatory papilla elongate and plicate, as in all the species of the genus; abruptly narrowed distally as in Lerneca inalata beripocone Lima, Martins & Lhano, 2016; widened before apex (Fig. 9K).
Measurements (in mm)
See Table 10.
REMARK
The specimens from French Guiana (Mitaraka, Kourou) and Venezuela correspond to Saussure’s 1874 description of L. inalata except for their larger size (Table 9). The specimens originating from Venezuela are also lighter in coloration and their HWs go well beyond FW tip by a mean length of 4.4 mm. HWs are absent or rudimentary in the type of L. inalata according to Saussure’s description, while they are shorter than FWs in Guianese specimens, showing a possible polymorphism for wing length, as documented in other cricket species. All observed specimens have very similar male genitalia (compare Desutter-Grandcolas 1992a, figures 28, 29 and Fig. 15 E-G); female genitalia are known for Venezuelan specimens only (Fig. 9K).
