Genus Storozhenkoa Gorochov View in CoL , gen. nov.

Type species: Storozhenkoa sergeyi Gorochov , sp. nov., designated here.

Diagnosis. Rather small crickets with general appearance typical of this subfamily, but also with distinctly spotted coloration, moderately long legs ( Figs 1–3 View FIGURES 1–3 ) and some characteristic features listed below. Head roundly triangular in front; rostrum between antennal cavities approximately as wide as scape; eyes very large, slightly higher than long, moderately convex; ocelli developed but very small and located in corners of transverse triangle; apical segment of maxillary palpus clearly widening towards apex, distinctly longer than subapical one, and almost equal to third segment of this palpus in length ( Figs 1–3 View FIGURES 1–3 , 4 View FIGURES 4–13 ). Pronotum almost as wide as head; its anterior and posterior parts slightly narrower; anterior and posterior edges of disc almost straight; lower lobes moderately low, roundly turning into disc and with slightly concave ventral edges ( Figs 1–3 View FIGURES 1–3 ). Fore tibia with only oval inner tympanum; fore and middle tibiae also with a pair of ventral apical spurs on each; hind femur distinctly widened, well adapted to jumps; hind tibia with rather short dorsal spines having short and not very dense hairs, and with only five apical spurs (ventral inner apical spur absent) which more or less similar to above-mentioned spines (but dorsal inner and middle inner spurs longer and with denser hairs); hind basitarsus with only a pair of small dorsal subapical spines near a pair of longer apical spurs. Male tegmina distinctly shortened, with developed stridulatory apparatus in dorsal fields and a few longitudinal and almost parallel Sc branches in lateral fields; aforementioned apparatus almost without mirror as well as with long and distinctly S-shaped oblique vein ( Figs 1, 2 View FIGURES 1–3 , 5 View FIGURES 4–13 ); female tegmina extremely small, lobule-like ( Figs 3 View FIGURES 1–3 , 11 View FIGURES 4–13 ); hind wings absent in both sexes. Metanotal gland absent; abdominal tergites and sternites as well as paraprocts and cerci also without specializations, but last sternite of female somewhat enlarged (longer than previous abdominal sternites; Fig. 12 View FIGURES 4–13 ); anal plate in both sexes lobe-like, with thin transverse fold in middle part of dorsum and with almost lamellar and rounded distal part directed more or less downwards ( Fig. 6 View FIGURES 4–13 ); male genital plate approximately as long as wide but distinctly longer than anal plate, with almost truncated posterior part ( Fig. 7 View FIGURES 4–13 ); female genital plate much shorter, slightly wider than long, with rather wide but not deep and more or less angular posteromedian notch as well as with short and almost rounded posterolateral lobules ( Fig. 12 View FIGURES 4–13 ). Male genitalia ( Figs 8–10 View FIGURES 4–13 ) rather short and wide; epiphallus somewhat semitubular, slightly flattened dorsally, almost rectangular from above but with large angular anteromedian notch and a pair of rather wide anterolateral lobes ( Figs 8, 10 View FIGURES 4–13 ); rami indistinct (fused with these lobes or even including in their bodies); ectoparameres large, well separated from epiphallus, stick-like but with widened proximedial parts which divided by carinae into medially vertical and laterally horizontal plates ( Figs 9, 10 View FIGURES 4–13 ); rachis very wide, short and membranous, slightly projecting behind epiphallus, and with a pair of short longitudinal sclerotized stripes on ventromedian surface ( Figs 8, 10 View FIGURES 4–13 ); endoparameres also rather short and articulated with these stripes but having long and thin endoparameral apodemes ( Figs 8, 9 View FIGURES 4–13 ); formula located near bodies of endoparameres, consisting of a pair of rather large semimembranous plates ( Fig. 9 View FIGURES 4–13 ). Ovipositor very long for this subfamily, thin and almost straight, with narrow and acute apical parts of valves lacking denticles and other relief ( Fig. 13 View FIGURES 4–13 ).

Included species. Only type species.

Comparison. This genus is more or less similar to representatives of the tribe Marinemobiini , as it lacks an inner ventral apical spur of the hind tibia and has long endoparameral apodemes in the male genitalia, but it is distinguished from Marinemobiini by the presence of tegmina in male and at least of one tympanum on the fore tibia. From the tribe Burcini , also having similar structure of the hind tibia, the new genus differs in the male genitalia having long endoparameral apodemes (these apodemes are absent in Burcini ). From the tribe Pteronemobiini , Storozhenkoa gen. nov. differs in the absence of glandular spine (spines) on the hind male tibia; from the tribe Lissotrachelini , in the presence of an oblique vein (absent in Lissotrachelini ) in the male tegminal stridulatory apparatus and of distinct sclerotized ectoparameres in the male genitalia, as well as in the absence of inner ventral apical spur in the hind tibia and of all dorsal spines (except for a pair of apical spurs) on the hind basitarsus; and from the tribes Nemobiini and Grylliscini as well as from some other genera with unclear tribal position, in the loss of one of the apical spurs in the hind tibia, short and weakly pubescent spines and spurs of this tibia, a characteristic shape of the oblique vein in the male tegmen, a longer ovipositor without denticles in the distal part, and/or the above-mentioned details of the male genitalia.

Etymology. This genus is named after the family name of the well-known Russian orthopterist S.Yu. Storozhenko in honor of his seventieth birthday.
