Elimaea (Rhaebelimaea) pseudochloris Ingrisch, 1998: 81

Material examined. Peninsular Malaysia, Pahang, Bukit Fraser , coll. M. K. Tan & S. T . Toh : 1 male, behind Shahzan Inn , shrub, N03.71137, E101. 73701, 1272 ± 9 m, stridulating, 23 December 2012, 2230 hours ; 2 males, along Mager Road , tall grasses, N03.70802, E101.73979, 1277 ± 7 m, 26 December 2012, 1957 hours ; 1 female, along Ledegham Road , shrub and tall grasses, N03.71806, E101.73991, 1280 ± 5.3 m, 20 May 2013, 2029 hours (all ZRC) .

Discussion. This species was described based on a single holotype male specimen from South Thailand. The male was sufficiently described in Ingrisch (1998). New material from Bukit Fraser allowed the description of the female for the first time. The new material also represents the first recording of this species outside Thailand, even though current knowledge suggests that species of the subgenus are highly restricted in distribution ( Ingrisch, 1998). Rhaebelimaea species tend to inhabit forest habitats but specimens collected from Bukit Frasers were also found on forest edge among shrub and tall grasses.

Diagnosis. Similar to Elimaea (Rhaebelimaea) bengkulu Gorochov, 2009 from Sumatra but differs by little or no spots on tegmen; less densely spaced teeth on stridulatory file of left tegmen; a longer and more curved male cerci, terminating into a long twisted cone and acute apex; conchate sclerite less elongated and more rounded; female subgenital plate elongated with apical margin roundly emarginated; gonangulum of ovipositor with a small nodular projection. Similar to Elimaea (Rhaebelimaea) viridula Gorochov, 2009 from Thailand but differs by wider and less elongated epiproct; conchate sclerite denticulate only in dorsal (proximal) half.

Description. Male is sufficiently described in Ingrisch (1998). Brown form exists, previously unknown ( Fig. 1A ).

Female. Abdominal apex as shown in Fig. 1B–1D . Tenth abdominal tergite with hind margin truncated, barely convex. Epiproct elongated tongue-shaped, apical half slightly bent dorsally, with apex obtusely rounded ( Fig. 1B ). Cerci curved internally and dorsally, conical; apex pointing ( Figs. 1B, C ). Subgenital plate elongated, 3.9 times longer than wide (n = 1); basal margin roundly truncated, apical margin very strongly (to apical third) and roundly excised, on each apical angle prolonged into a straight spinose projection ( Figs. 1C, D ). Ovipositor short sabreshaped; ventral margin roundly curved dorsally, dorsal margin bent dorsally; margins in about apical half denticulate; gonangulum of ovipositor with a small nodular projection posterior-ventrally ( Fig. 1C ).

Measurements. See Table 1.
