Eupholidoptera gemellata Willemse & Kruseman, 1976: 136.

Eupholidoptera gemellata Morphological description. Willemse and Kruseman 1976: 137.

Remark.

The species was described after a single male was collected in 1973. Pitfall catches made in 2000-2001 at Mt. Psiloritis at 1950 m above Lochria and Agia Marina caught 11 males and 8 females. Opportunity is taken here to describe the female and illustrate important morphological structures with stacked images.

Examined specimens.

Holotype, 3 ♂, 2 ♀ (for details see Suppl. material 2).

Diagnostic features.

Frontal part of head (Fig. 12 View Figures 11–24 ) pale with two larger and two smaller dark dots; pronotal disc (Fig. 26 View Figures 25–38 ) pale with irregular small or large black patches or largely blackish, posterior quarter to third pale; narrow band along anterior margin fourth to ninth abdominal tergites black. Male - stridulatory file with 101 teeth (including proximal and distal ones), density of teeth in middle two thirds of the file 22 teeth per mm; anal tergite (Figs 70 View Figures 69–82 , 84 View Figures 83–96 , 98 View Figures 97–110 ) wide, distally bend downward centrally forming two inward pointing, overlapping, spines separated by short circular excision; cerci (Figs 112 View Figures 111–125 , 127 View Figures 126–139 ) 4-5 × longer than wide, conical, straight in profile and dorsal view, armed with inward curved inner sub-basal rectangular sidetooth; subgenital plate (Figs 141 View Figures 140–153 , 155 View Figures 154–167 ) ca. as wide as long, proximally widest, sides rimmed except in apical quarter, in profile, narrowing, straight, pointing backward, tip apical lobes widely truncate with a protuberance on the inner margin and strong upward and backward pointing curved spine at base of stylus, with V-shaped excision along one third of total length; styli (Fig. 169 View Figures 168–181 ) long, more than half as long as cerci, 3 × longer than wide, conical, inserted at tip of apical lobe, pointing backwards; titillator (Figs 183 View Figures 182–197 , 199 View Figures 198–212 ) symmetrical, weakly sclerotised, basal arms short, apical arms fused, in apical quart widened and split, tip truncate, unarmed in profile S-shaped from base to tip equally wide.

Description.

Female. Examined specimens. 2 ♀: RETHIMNO: Psiloritis, above Lochria, FC1602 1♀ RMNH.INS1141844 (RMNH) 1♀ 2000.095.02 (CT). For more details, see Suppl. material 2.

General appearance and size as male (Figs 232 View Figures 224–235 , 233 View Figures 224–235 ). Colouration as male. In dorsal view wings covered by pronotum, in profile hardly visible, light coloured. Cercus short, conical, slightly more than half as long as subgenital plate, straight in profile and in dorsal view, conical, tapering in apical third toward a pointed tip, densely covered with pale short and long hairs. Subgenital plate (Figs 50 View Figures 39–52 , 54 View Figures 53–66 ) wider than long, in profile triangular, in ventral view trapezoid, basally widest, hind margin medially with wide shallow excision; surface basally and centrally convex, laterally flattened, thinly covered with hairs; ovipositor proximal two thirds straight, apical third slightly curved upward, 1.4-1.9 × longer than pronotum.

Bioacoustics.

The song of this species has not yet been recorded.

Differential diagnosis.

Males differ from congenerics in the stout, straight cercus (Figs 112 View Figures 111–125 , 127 View Figures 126–139 ) with sub-basal rectangular side-tooth, in the subgenital plate (Figs 141 View Figures 140–153 , 155 View Figures 154–167 ) narrowing into a truncate tip with upward and backward pointing spines, the inner margin of the excision with a protuberance, in the long, apically inserted styli (Fig. 169 View Figures 168–181 ) pointing backward, in the anal tergite (Figs 70 View Figures 69–82 , 84 View Figures 83–96 , 98 View Figures 97–110 ), medially bent downward forming a small circular excision adjoined by two partly overlapping, inward pointing spines and in the titillator (Figs 183 View Figures 182–197 , 199 View Figures 198–212 ) with short basal arms and fused and adjoined apical arms with widened and truncated tip. Females differ in the wide, convexly rounded subgenital plate (Figs 50 View Figures 39–52 , 54 View Figures 53–66 ), hind margin centrally with wide shallow excision. Eupholidoptera gemellata closely resembles E. pallipes but males differ in the apical arms of the titillator apically not being fused in E. gemellata (Fig. 183 View Figures 182–197 ) and fused with small lateral spinelets in E. pallipes (Fig. 184 View Figures 182–197 ). Females of both species differ in the shape and the hind margin of the subgenital plate (compare Fig. 40 View Figures 39–52 with Fig. 41 View Figures 39–52 ). In colouration E. gemellata is easily recognisable by the head with larger frontal black dots, the extensive blackening of the pronotal disc and narrow anterior transverse black band in the abdominal tergites. For more details differentiating E. gemellata from other Cretan Eupholidoptera see Table 5 View Table 5 .

Distribution.

The holotype was collected on Mt. Idi at 1650 m near the spring of Skaronero. Additional specimens collected in pitfall traps at a site northwest of Skaronero at 1950 m above Lochria between 15 September 2000 and 12 June 2001 (Fig. 255 View Figures 254, 255 ). For a complete list of localities, specimens, and repositories see Suppl. material 1.

Habitat.

Rocky mountain slopes with phrygana.

Phenology.

The holotype was collected at 1650 m on 28 July. The pitfalls that trapped the species were positioned at 1910 m and emptied on 15 September and 30 October 2000, and again on 12 June 2001.
