Anadolua schwarzi autumnalis Ünal, ssp. nov.

( Figs. 159–160, 163–174 )

Type locality. Turkey: Bolu Prov., Feruz Köyü , 1340 m .

Description. Male (Holotype). Fastigium of vertex as wide as antennal scape, 2.6 times wider than frontal groove. Pronotum ( Figs. 165, 166 ) long, cylindrical in prozona; metazona distinctly widened, flattened and extended posteriorly and moderately raised in lateral view; shoulder incision distinct; 1.7 times longer than high, and 1.1 times longer than fore femur; first transversal groove distinct; anterior margin slightly concave, posterior margin convex, with a weak and small incision in the middle; without median and lateral carinae. Tegmina ( Figs. 165, 166 ) reaching slightly beyond the middle of second abdominal tergite; 1.3 times shorter than pronotum. Hind femur long, 2.8 times longer than pronotum, slightly shorter than body length, with 5 outer and 4 inner ventral spines; inner and outer apical lobes with a very small spinule. Prosternum with two small triangular projections. Last abdominal tergite ( Fig. 167 ) short and wide, with 2 tongue-shaped posterior lobes, and with a very deep posterior incision reaching almost the previous tergite. Subgenital plate ( Fig. 168 ) as wide as long, but it was compressed laterally during the preparation process; therefore, it is wider in natural forms; with a longitudinal swelling behind the stylus, and with a distinct median carina between them; posterior incision almost absent, very slightly concave; styli shorter than the distance between them. Cercus ( Figs. 159, 167 ) very short, proximal part cylindrical up to inner tooth, with an inner tooth in the middle of cercus, with slightly recurved apical denticle; distal part after inner tooth strongly narrowed; apex truncate with a very indistinct tubercle (not a spine or tooth), in the inner corner of truncate apex, makes this corner weakly pointed. Titillators ( Fig. 160 ) with long and thin apical arms, compressed laterally, with 3–4 sharp outer teeth apically; basal arms long and flattened like a narrow plate, strongly upcurved, reaching 1/3 of apical arms, apical part distinctly curved forward in lateral view.

Female (Allotype). Fastigium of vertex 1.1 times narrower than antennal scape; 2.6 times wider than frontal groove. Pronotum ( Figs. 171, 172 ) as in male, 1.8 times longer than high, 1.2 times longer than fore femur. Tegmina reduced, scale-like laterally, fully concealed under pronotum. Legs as in male, slightly larger. Hind femur 2.6 times longer than pronotum and 1.1 times shorter than body, with 2–3 outer and 3 inner ventral spines. Prosternum as in male, but with less distinct projections. Last tergite very short and wide, divided into two lateral parts with very deep posterior incision as in male; this incision is part of supra anal plate just below it. Cercus simple, narrow, conical, pointed at apex. Subgenital plate ( Fig. 173 ) 1.1 times wider than long, with a wide and shallow triangular posterior incision; ventral view with a longitudinal bow tie-shaped depression along the middle axis; posterior part of this depression with transversal ridges; basal 1/3 part with a median carina. Anterior margin of 7 th sternite ( Fig. 173 ) narrowed and slightly inflated as in the nominotypical subspecies. Ovipositor ( Figs. 169 , 174 ) straight, very long and narrow, as long as body; in some paratypes longer; distinctly longer than hind femur.

Colouration. Body ground milky or greyish brown, marbled with irregular and small black, brown spots, stains and marks. Antennal scapes with partly brown marks, between them (just upper and lower parts of frontal groove) black, which form a narrow dark band between eyes in both sexes, but in 2 females body unicoloured milky brown and the dark band between the eyes absent. Antennae light brown. Pronotum with poorly visible, typical X-shaped darkening on dorsal surface. Male tegmina brown.All legs just before the knees with a transversal and irregular dark band (ring); knees milky brown. Hind femur with a large black spot at the base dorsally.

Discussion. This new subspecies is easily separated from A. schwarzi Ramme, 1939 s. str., A. burri Karabağ, 1952 and A. davisi Karabağ, 1952 by the male cercus ( Figs. 157, 159, 161 and Fig. 227 of Ünal 2018), titillators ( Figs. 158, 160, 162 ), female subgenital plate (from A. burri and A. davisi ), ovipositor (from A. burri and A. davisi ) and pronotum in both sexes. It is naturally most similar to the nominotypical subspecies in the general appearance of the body, colouration, male last tergite, female subgenital plate and ovipositor. But, inner tooth of male cercus is in the middle [in A. schwarzi schwarzi , ( Fig. 157 ) inner tooth much smaller, clearly in proximal part near to base of cercus, and its base not projected), the shape of pronotum in both sexes which longer, more slender, extended posteriorly and raised; with distinct shoulder incision [in A. schwarzi schwarzi pronotum ( Figs. 213, 214 of Ünal 2018) short, stout, not extended posteriorly; shoulder incision very weak; dorsal margin straight in lateral view, not raised in metazona], the male subgenital plate without or with very weak posterior incision (in A. schwarzi schwarzi , male subgenital plate with a deep rounded posterior incision) separate from the nominotypical subspecies (compare with all the figures of Anadolua spp. in Ünal 2018 which includes the type specimens). This new species is separated from A. moli Şirin, Sevgili et Taylan, 2024 as in A. schwarzi s. str. (see A. schwarzi schwarzi above).

Length of body: male 19.6–22.3, female 21–23.7; pronotum: male 6.4–6.6, female 7.2–7.7; tegmina visible: male 4.9–5.2; hind femur: male 17–17.6, female 20.2–21; male cercus 1.5–1.6; ovipositor: 23–24.1.

Material examined. Turkey: Bolu Prov., Mudurnu Yolu, Feruz Köyü , 1340 m, 40°34.342´N, 31°20.799´E, 25.10.2022, 1 female; 1.11.2022, 3 males (including holotype), 4 females, 2 females in alcohol; 27.10.2023, 3 males, 6 females in alcohol (leg. M. Ünal ) ( AİBÜEM) .

Etymology. This new taxon has not been observed during the summer, despite numerous field trips to the type locality conducted by the author. The most recent attempt to find it was in August 2024. However, it was discovered at the end of September and the beginning of October, indicating that it is an “autumn” insect.

Remarks. Geographically, this is the first member of the genus Anadolua found in the Black Sea Region of Turkey, which is within the Euro-Siberian phytogeographical region. The genus Anadolua is mainly a Mediterranean element.
