Eotmethis aguitiensis sp. nov. ( Figs. 1 View FIGURES 1–10 –11)
Holotype. ♂, Mongolia, Southgobi province , Khanbogd sum, near the Khaalga spring, 42°40’ N 107°53’ E altitude 1110 m, 2013-VIII-23, collected by Myagmar. GoogleMaps
Male. Body medium in size ( Fig. 1 View FIGURES 1–10 ). Antennae filiform, 19 segmented (include pedicel), almost reaching to the hind margin of pronotum, length of the middle segments 1.7-1.8 times as long as wide ( Fig. 2 View FIGURES 1–10 ). Dorsal side of head depressed, with granular tubercles and wrinkles ( Fig. 3 View FIGURES 1–10 ). Frontal ridge apparent, whole length with a groove, length of process between the antennae of frontal ridge shorter than 1.5 times transversal diameter of eyes ( Fig. 6 View FIGURES 1–10 ). Between eye and base of antennae with distinct ridge in lateral view ( Fig. 6 View FIGURES 1–10 ). Median ocellus placed in the ventral slope surface of projection, but visible in frontal view ( Fig. 4 View FIGURES 1–10 ). Preocellar foveola stretched and more distinct visible than supraocellar foveola ( Fig. 3 View FIGURES 1–10 ). Pronotum rough, with relatively small subuliform projections, anterior and posterior margin angled protruding; median carina elevated into lamellate, its hind transverse sulcus incised deeper than fore and mid transverse sulci; length of prozona slightly longer than metazona. Prosternum with a strong lamellate process on the anterior margin which undulated by several small tubercles ( Fig. 7 View FIGURES 1–10 ). Interspace of mesosternum lateral lobes trapezoid, wider and the width of the narrowest part 1.4 times larger than width of broadest part of lateral lobes.
Tegmina well developed, the apex reaching to distal third of hind femur ( Fig. 5 View FIGURES 1–10 ). Hind wings R vein with two branches, M and Cu veins without branches. Hind femur wide and compressed, its median carina on upper side serrated. Hind tibia with 9 spines on outer side and inner side (including apical spine), apex of its spines dark. Subgenital plate short, its apex broadly rounded (from above). Epiphallus wide larger than length shown in fig. 10.
Coloration. Body and tegmen browny with distinct dark spots. The dark stripe of the hind wing does not reach the 6th disc and the widest part of the dark stripe on the 3rd wing disc ( Fig. 5 View FIGURES 1–10 ). Hind femur with a distinct dark band on outer side ( Fig. 8 View FIGURES 1–10 ). Inner lower marginal area of hind femur has reddish orange strip that starts at its base but disappears before half way to its tip ( Fig. 9 View FIGURES 1–10 ). Inner side of hind tibia in base and apical part red, remaining part dark blue. First tarsomere reddish from inner and dorsal view (Fig. 11).
Male. Measurement (in mm): Length of body: 23.0; Length of tegmina: 9.8; Length of pronotum: 6.8; Length of hind femur: 14.0. Female: unknown.
Diagnosis. The new species is different from most of known species by the next characters: However, posterior margin of pronotum without distinct row of subuliform projections, color of hind femur, tibia and tarsus, shape of lamellate process of prosternum, preocellar and supraocellar foveolar but most similar to E. nasutus Bei-Bienko, 1948 , and the major differences were mentioned in below ( Table 1 View TABLE 1 ).
1948.
Female unknown.
Etymology. The species is named Aguitiensis, the name derived from the mountain name “Aguit”.
