Remark.

Pitfall catches collected on Mt. Dikti at a site above the Limnakaro plateau trapped a total of 127 specimens of Eupholidoptera which at first glance were identified as E. forcipata . Closer examination however revealed differences with E. forcipata based on which a species new to science is described here.

Description.

Male. General appearance (Figs 236 View Figures 236–239 , 237 View Figures 236–239 ) as type species E. chabrieri , more compact. Pronotum hardly widening posteriorly, metazona relatively short, hind margin slightly convex. Legs short and thick, hind femur 1.7-1.9 × as long as pronotum (2.0-2.2 in E. chabrieri ), mid and hind femur ventrally unarmed.

Stridulatory file with 211-216 teeth (including proximal and distal ones), density of teeth in middle two thirds of the file 37-42 teeth per mm.

Anal tergite (Figs 81 View Figures 69–82 , 95 View Figures 83–96 , 109 View Figures 97–110 ) in dorsal view narrow in the middle, laterally widening, in the middle folded downward, centrally forming large pale coloured hairy patch in the centre, laterally with striae, hind margin somewhat swollen, from the ventro-lateral corner folded around cerci, extending straight down- and inward, toward the middle forming two wide downward pointing lobes with teethlike tip separated by a wide excision.

Cercus (Figs 124 View Figures 111–125 , 138 View Figures 126–139 ) compact, unarmed, conical, weakly and gradually curved inward in basal half, in profile slightly upturned, 4 × as long as the greatest width.

Subgenital plate (Figs 152 View Figures 140–153 , 166 View Figures 154–167 ) very compact, 1.5 × wider than long, widest at one third of the length, proximal margin slight concave; in profile compact, lower margin straight ca. halfway bent upward, hardly narrowing apically, apical part pointing upward in situ covering last abdominal segment; ventral surface with a strong median keel, proximal half depressed next to the keel, halfway transversely depressed, apical half divided into two flattened triangular lobes, tip straight truncated, without a spine, surface irregularly gibbose, laterally with straight rod-like protuberances; lateral margin in ventral view a folded back rim, thickened near the base, apically disappearing under the rod-like protuberances, in profile straight with a proximal nod; posterior margin with a very wide V-shaped median excision along more than half the total length, edges straight toward the middle weak convex. Styli (Fig. 180 View Figures 168–181 ) short, 2 × longer than wide, conical, inserted at the tip of the apical lobes pointing backward and upward.

Titillator (Figs 196 View Figures 182–197 , 211 View Figures 198–212 ) symmetrical, apical arms in dorsal/ventral view in lower half narrow, almost stalk-like apically widening, swollen, two apical arms diverging into two very long and slender hooks, smooth except for some wrinkles, near the apex curved inward; in profile stalk like basal half weakly S-curved, transition with apical half distinct, apical hooks evenly curved backward and upward, reaching or extending above the anal tergite.

General colouration (based on specimens kept in alcohol) yellowish brown. Head with the frontal part below antennae and eyes pale with two black dots (Fig. 23 View Figures 11–24 ), the lower part frons and upper part clypeus with large transverse black patch, upper part around the eyes and antennal sockets black, occiput behind the eyes and in the middle with black patches. Pronotal disc (Fig. 37 View Figures 25–38 ) pale yellowish with central black markings at best resembling an open “W” or frontal half with large central black patch forming transverse or V-shaped border with pale rear half; lateral lobes with wide black dorsal fascia, not sharply delineated ventrally, posteriorly narrowing not reaching the hind margin. Elytra black. Fore and middle legs with few black dots and stripes, concentrated around the knee. Hind femur dorsally with black basal patch and apical black stripe, outer side near the base with or without a series of transverse stripes, pre- and post-genicular part black. Anal tergite black, subgenital plate laterally below the dorsal margin black.

Female. General appearance (Figs 238 View Figures 236–239 , 239 View Figures 236–239 ) as male. Elytra clearly visible in profile. Cercus conical, hairy, bent inward, narrowing in apical fifth, apex pointed. Subgenital plate (Figs 51 View Figures 39–52 , 65 View Figures 53–66 ) shiny, smooth with very few hairs, 1.5 × wider than long, greatest width in proximal third; in ventral view, convex with a median ridge, proximally with two distinct, dark coloured concavities, apically flattened, hind margin with a wide acute V-shaped median excision along one third of the length, corners obtuse rectangular; in profile oblong, ventrally with a distinct basal depression and more shallow apical depression, lower edge convex, distally upturned, tip obtuse angular. Ovipositor 2.0-2.4 × as long as pronotum, straight, in apical quart weakly upturned. Colouration as the male, transverse black patch at the transition between frons and clypeus more pronounced; elytra pale; first abdominal segment black.

Bioacoustics.

The song of this species has not yet been recorded.

Differential diagnosis.

Males differ from congenerics in the pointed back- and downwardly extended widened lobes of the anal tergite (Figs 81 View Figures 69–82 , 95 View Figures 83–96 , 109 View Figures 97–110 ) with tips pointing downward and slightly outward, in the wide upturned, spineless subgenital plate (Figs 152 View Figures 140–153 , 166 View Figures 154–167 ) with a very wide V-shaped excision, in the short, apically inserted styli (Fig. 180 View Figures 168–181 ) pointing backward, in the stout, weakly inward curved cerci (Figs 124 View Figures 111–125 , 138 View Figures 126–139 ) and the symmetrical apical arms of the titillator (Figs 196 View Figures 182–197 , 211 View Figures 198–212 ), in basal half fused and narrow, in apical half strongly diverging hooks. Females differ from congenerics in the very wide subgenital plate (Figs 51 View Figures 39–52 , 65 View Figures 53–66 ), proximally with two concavities, tips rounded with U-shaped excision along quarter of the length. Eupholidoptera marietheresae sp. nov. closely resembles E. forcipata but differs in the male by the thin, apically incurved apical arms of the titillator, the compact weakly incurved cercus lacking the subtle bulge halfway the inner side and the anal tergite with wider downward expansion combined with a narrower excision and in the female in a more elongated subgenital plate, with the proximal pits being close together. In colouration, E. marietheresae sp. nov. differs from all Cretan congenerics except E. pallipes in the large transverse black patch on the lower part of the frons. For more details differentiating E. marietheresae sp. nov. from other Cretan Eupholidoptera see Table 5 View Table 5 .

Distribution.

Only known from a single location on Mt. Dikti above the Limnakaro plateau where the species was trapped in pitfall traps (Fig. 255 View Figures 254, 255 ). For a complete list of localities, specimens and repositories see Suppl. material 1.

Habitat.

Mountain slopes at 1700 m in phrygana vegetation.

Phenology.

Pitfall traps in which the species was found were checked irregularly. Based on the three catching periods, adults can be found prior to early August up to at least early October.

Etymology.

The species is named in honour of Marie-Therèse Willemse-Dresen (1929-2017) wife and lifelong companion of Fer Willemse who contributed a large part of his entomological career to the study of the Orthoptera fauna of Greece, describing 40 species new to science from Greece, including four Cretan species of Eupholidoptera . In his last, and most challenging, paper on Chorthippus (Glyptobothrus) from Greece ( Willemse et al. 2009) he wrote in the acknowledgements:

" This publication would not have been possible without help from my family. My wife’s patience and tolerance to my single-minded enthusiasm was almost boundless. Both the long hours spent during our travels in seemingly dull and uninteresting areas, as well as at home recording and studying have been accepted without much ado. For that I owe her an enormous amount of gratitude. "

It is in this spirit that we pay a tribute to Marie-Therèse. The fact that E. marietheresae sp. nov. is found on the same mountain and in the vicinity of E. feri , a species named after Fer Willemse, is making it even more appropriate.
