(Figs 8 I, 12 A–I, 13 A–H, 17)  
 Phyllodromica subaptera morph #4. —Knebelsberger & Bohn, 2003.   
 Holotype: ♂, Spain, Prov. Granada, Sa. de Baza, ca. 15 km WSW Baza, 1100 m, 20.–23.III.2001, leg. T. Knebelsberger (on two slides, Sp203d/M1); deposited in ZSM.   
 Paratypes: 5 ♂, same data as holotype. Sp 203d/M11 (frozen DNA; parts of body in 98 % ethanol); Sp 203d/M12 (frozen DNA; parts of body in 98 % ethanol); Sp 203d/M2 (on two slides); Sp 203d/M3 (on two slides); Sp 203d/M9 (on two slides).   
Paratype DNA and associated parts of body are stored in the DNATAX collection of ZSM under storage numbers DNATAX02867 (Paratype Sp 203d/M11) and DNATAX02868 (Paratype Sp 203d/M12). The sequences were submitted to GenBank under the accession numbers: AM 600691 (DNATAX02867) and AM 600692 (DNATAX02868). The remaining 3 paratypes (Sp 203d/M2, 3, 9) are deposited in the private collection of T. Knebelsberger.  
 Additional material. Numerous specimens from the following localities: Spain. Sp 191, a, 195, 203, a, b, c, d, 207, a, 472, a, b, 473, a, 493, 495, 497, 498, 499, 500, 501, 502, 504, a.   
 Etymology. The name of the species refers to the presence of only 4 distal tibia spines on the second pair of legs in males.   
 Description. Size. Length of pronotum: ♂ 1.35–1.56 (mean 1.45) mm; ♀ 1.71–1.90 (mean 1.81) mm.   
 Legs. Distal end of mid tibia with only 4 spines (Fig. 14 C), females rarely 5.   
Male  
 Tergites. —Tergite 6. Emargination of the posterior border relatively broad and less deep than in the other species, without torus behind the transversal ridge (Fig. 12 C). Tergite 7. Median lobe long, at least as long as the distance between the bristle fields and the posterior border of the tergite, covered with numerous glandular pores (Figs 12 D, 13 A). Trough very shallow, almost in the plane of the tergite surface. Mound flat, mainly elevated behind the bristle fields. Bristle fields moderately large, in outline broadly oval to circular, immediately adjacent, rarely separated by a very narrow bristleless ridge, posteriorly appearing deepened by the elevating surface of the mound; bristle fields with indistinct borders (Fig. 13 A). The male from locality Sp 504a (Fig. 14 E–G) differs slightly in the morphology of the bristle fields: the bristle fields are somewhat larger and slightly separated by a bristleless ridgelike structure (Fig. 14 F). Tergite 8. Without any sculpturing on the surface, rarely with weak depressions at the base of the anterior processes; membraneous incision between the anterior processes narrow (Figs 12 E). Note: The membraneous incision between the anterior processes appears relatively broad due to an unnatural stretching of the tergite during preparation (Fig. 14 G). Cone completely missing (Fig. 13 C); without median gap in the distribution of the bristles (Fig. 13 B). Tergite 10. Supraanal plate broadly rounded (Fig. 12 G).   
 Sternites. —Paraproct. Medio-anterior process of the right parapoct with a bulge (bu) at the base (Fig. 14 B).   
 Genitalia. — Helmet sclerite. “Frontal” part (fr) broadly rounded, in the “rear” (re) with a relatively long acuminate process (Fig. 14 D) (in P. iberica the anterior part and the acuminate process of the helmet sclerite are reduced (Fig. 8 E)).   
 Colouration. —Tergites 2–5. Dark anterior area often with short posterior extensions (Fig. 12 B). Tergite 6. Dark area broadly reaching the posterior tergite border, behind the transversal ridge often with small lightenings medially and/or along a transversal line at some distance from the ridge (Figs 12 C, 14 E). Tergite 7. As in tergite 6 with dark area broadly reaching the posterior border, central and posterior part darker than the remainder, bristle fields and immediate surroundings not seldom lightly coloured, trough in the middle with a whitish patch (Fig. 12 D) as in the other species. Tergite 8. Dark posterior extensions medio-laterally usually not strongly pronounced, median extension often well developed (Fig. 12 E).   
Female  
 Legs. Distal end of mid tibia usually with only 4 long spines, rarely with a fifth short spine in ventro-posterior position.   
 Genitalia. No additional sclerotization in the angle between intercalary sclerite and the posterior lobe of valvifere II, the latter very broad, egg-shaped (Fig. 13 G).   
 Colouration. Disk of pronotum regularly mottled with variously shaped dark spots; anterior border never with a dark crescent (Fig. 13 D). Transparent margin of the pronotum not well set off, especially anteriorly and in the latero-posterior region with numerous small dots. Meso- and metanotum with dark anterior part ending shortly behind the transversal ridge, from there with 6 to 7 bar-shaped posterior projections, remaining surface quite regularly mottled.   
 Genetic Data. 1597 basepairs of the mitochondrial genome including the complete cytochrome c oxidase subunit I (COI) gene were analysed. in two paratype specimens (Sp203d/M11, Sp203d/M12). The sequences of Phyllodromica quadracantha _ Paratype Sp203d/M11_1585bp and Phyllodromica quadracantha _ Paratype Sp203d/M12_1585bp differ in 19 positions (Appendix 5). The complete sequences are shown in Appendix 4.   
 Geographical distribution (Fig. 17). Relatively small distribution area in the southeast of Spain separated from other bisexual species. One isolated population (Sp 504) has been found further northeast.   
  Other species of the subaptera -group found.  P. subaptera: Sp 191, 195, 203, 207, 472, 473, 493, 495, 498, 504.   
 Remarks. At the locality Sp504 only one male (and some females) has been found. It shows remarkable differences in the structures of tergite 7, which might indicate a taxonomic separation. More material is necessary to clarify the situation.
