Mirollia carinata abnormis Otte 1997, Orthoptera Species File 7: 179 Mirollia abnormis Gorochov 2008, Euroasian Entomol. J. 7: 319 Material studied: East Malaysia, Sabah: 1 male, Bergil (fogg tree Nr. 7), 5°57'N, 37°55'E, leg. A. Floren (ZFMK); 2 females, Sandakan District, Rumidi Estate, River Labuk [5°54'N, 117°30'E], 15–45 m, 14–30.ix.1973, leg. C.J.M. Pruett (BMNH).
Discussion. M. abnormis was recently raised to full species status by Gorochov (2008). This is confirmed. Additional information on stridulatory apparatus and abdomen is given.
Description. Fastigium verticis furrowed; step-like descending anteriorly (Fig. 11A). Pronotum with medial carina interrupted by second transverse sulcus; posterior margin weakly convex, almost truncate in middle; disc with rounded lateral angles; paranota little longer than deep.
Male. Stridulatory file on underside of left tegmen concave and little curved; 2.04 mm long; teeth in basal third extremely dense, towards centre and apex dense; with 156 teeth, equating 76 teeth per mm; at base with 17.6, in middle to apical area with 4.0 teeth per 0.1 mm (Fig. 13B). Mirror on right tegmen roughly oval with anterior margin straight; at end of basal quarter with incomplete cross-vein in outer area and curved weak depression in inner area; posterior bordering vein with minute teeth on top; 2.61 mm long, 1.91 mm wide; index length: width 1.36 (Fig. 12B). Second abdominal tergite in middle densely covered with long hairs, to which some secretionary substance was sticking in the specimen studied (Figs. 9H–I). Cerci with S-curved apical part (Fig. 14E). Subgenital plate with narrow parallel-sided posterior area; at apex divided into two angular lobes (Fig. 14D). Phallus provided with three pairs of sclerites (Figs. 16C–D): a central pair with straight basal and curved dentate apical half, a very short, straight, intermediate pair with two large denticles at apex, and a lateral pair with narrow basal and very wide apical half, and with broad, little sinuate, dentate apical margin.
Female. Subgenital plate transverse; apex in middle widely excised with little projecting triangular bottom and obtusely projecting short lateral lobes (Figs. 20A, 21A). Cerci rather thin; in apical area strongly curved mediad and subacute.
Coloration. Yellowish brown, probably green when alive. Scapus and pedicellus with black band on dorsal surface. Pronotum with two black dots on disc between first and second sulcus. Tegmen with piles of little distinct dark dots along hind margin and with two rows of little larger black dots (Fig. 2B); stridulatory area of left male tegmen with stridulatory vein and surrounding area brown (Fig. 12A). Fore tibia with dark lines at both sides in tympanal area. All tarsi with third segment dark brown. Hind femur with a row of red dots along dorsal margin in narrow posterior area. Hind tibia with ventro-external spines sitting on black dots. Antennae annulated.
Measurements (1 male, 2 females). Body w/wings: male 29.5, female 29–30; body w/o wings: male 20, female 16.0–17.5; pronotum: male 3.8, female 4.0–4.2; tegmen: male 21, female 21.5; hind wing: male 25, female 25; hind femur: male 11.8, female 11.5; ovipositor: female 5.8 mm.
