Named in honour of the well known Bulgarian zoologist Dr Dimo Bozhkov; name in genitive case.</p> <p> <b> <i>Diagnosis</i>.</b> The new species fits well to the <i>campestris</i> species group. Closely related to <i>M. rilaensis</i> (Deltshev, 1993) and <i>M</i>. <i>montana</i> (Deltshev, 1993). The three species can be clearly distinguished by the following characters. The palpal organ is the smallest in <i>T. montana</i> and most massive in <i>M. bozhkovi</i>. Furthermore, there are differences in the shape of tibial and tegular apophysis and in the relief and size of the conductor (Figs 1–4). It resembles also the species <i>M</i>. <i>parvula</i> (Thorell, 1875) and <i>M. ramblae</i> (Barrientos, 1978) but differs from them distinctly by the tibial apophysis, absence of tibial kiel (well developed in <i>M. ramblae</i>) and differences in the form and size of the conductor. Females of the regarded species differ mainly by their genital plate wider than high (quadratic by <i>M</i>. <i>parvula</i>). Genital openings are slant by <i>M. bozhkovi</i> <b>sp. nov.</b>, horizontal by <i>M. rilaensis</i>, situated on transversal narrow furrow by <i>M. montana</i>, and situated in quadratic atrium by <i>M. ramblae</i> and <i>M</i>. <i>parvula</i>. There are also differences in the position and number of windings of genital ducts (Barrientos 1978, Barrientos & Ribera 1992, Deltshev 1993).</p> <p> <i>Description</i>.

Borderline distinct, with some dark markings diffusing inwards. Anterior eyes touching, median eyes smaller that laterals. Posterior eyes almost equally spaced.

All these taxa are phenetically similar, they have limited ranges (West Rhodopy, Pirin, Rila) and probably, represent the descendants of a common ancestor.</p>Published as part of <i>Deltshev, Christo, 2008, Two new spider species, Malthonica bozhkovi sp. nov. and Tegenaria paragamiani sp. nov. from Rhodopy Mountains (Bulgaria and Greece) (Araneae: Agelenidae), pp. 37-44 in Zootaxa 1872</i> on pages 38-40, DOI: <a href="http://zenodo.org/record/183972">10.5281/zenodo.183972</a>

Tegenaria paragamiani Deltshev, 2008, sp. nov.
No full textTegenaria paragamiani sp. nov. Figs 9–16 Type material. Holotype male, Greece, East Rhodopy Mts, Maronia vill, Maronia Cave, 250 m, 1 male and 1 female paratype, 7.– 13.02.2004, leg K. Paragamian, all SMF. Etymology. Named in honour of the well known Greek biospeleologist Kaloust Paragamian; name in genitive case. Diagnosis. The new species fits well to the domestica species group, closely related to Tegenaria angustipalpis Levy, 1996 (Levy 1996). The male palps of both species are very similar, characterised by slender and elongated cymbium and tibia. The cymbium of T. angustipalpis is distinctly longer. Differences are present also in the shape of dorsal and lateral apophysis of tibia. The conductor of M. paragamiani sp. nov. is more slender and rounded, terminal apophysis and embolus seems to be longer. Females of both species are well discernible. The epigyne and vulva of T. paragamiani sp. nov. are characterised by simple atrium and two rounded spermathecae while by T. angustipalpis the genital openings are slanting provided with long and folded ducts. Description. Male holotype: Total length 7.12; prosoma length 3.37, width 3.00; sternum length 1.87, width 0.75; opisthosoma, length 3.75. Dorsal shield of prosoma similar in both sexes, brown to yellow brown. Anterior median eyes close, less of one diameter apart from laterals. Posterior eyes almost equally spaced. Chelicerae brown, anterior (posterior) margin with 3 (4) teeth. Sternum grey with light median line. Opistosoma also grey. Spinnerets yellow. Legs yellowish, leg measurements as in Table 3. Leg formula: I/IV/II/III. Male palp (Figs 9–14): Cymbium and tibia slender and strongly elongated. Dorsal apophysis developed as sharp tooth, lateral aphophysis also well developed as rotund outgrowth. Tegular apophysis with wide base. Conductor slender and rotund. Embolus short and thick, pointed. Female: Total length 6.37; prosoma length 3.00, width 2.32; sternum length 1.65, width 1.50; opisthosoma, length 3.37. All characters as described for male.

Holotype ♂, FYR Macedonia, Skopje, Maxari (240 m a.s.l.), grass vegetation, 02.X. 2004. Paratypes: 1 ♀, same data as for the holotype; 1 ♂, 19.IX. 2004, also from Maxari; 1 ♂, Skopje, Karpoš (253 m a.s.l.), grass vegetation, 23.VI. 2004 (all leg. D. Stefanovska). Etymology. Derived from the Roman name of the city of Skopje - Scupi. Diagnosis. Somatic characteristics of the new species correspond to those of the genus, but the genitalia differ from all other known species of the genus. Morphologically, the new species most closely resembles A. hodna Bosmans, 1999 and A. lineata (Simon, 1878), but the male is distinguished by the slender embolus, median apophysis with well-defined hook apically and thicker tibial apophysis (Figs 4, 5, 10, 11); the female can be distinguished by the median septum strongly narrowing posteriorly, and the distinct curved and oblique spermathecae (Figs 8, 9, 12, 13). Description. Male holotype: Total length 4.68; prosoma, length 2.16, width 1.80; sternum length 1.36, width 1.08; opisthosoma, length 2.52. Carapace yellowish, with anastomosing, radiating stripes (Fig 2). All eyes subequal, except ALE whose diameter is about 30 % larger than that of other eyes. AME almost touching, separated from ALE by 1 / 2 their diameter. Clypeus slightly larger than diameter of AME. Chelicerae yellow, with three teeth along promarginal cheliceral rim, middle one largest, two teeth on retromarginal rim. Abdomen grey to pale grey (Figs 2, 3). Legs yellowish to yellow-brown (Figs 2, 3).

Leg formula 4123, measurements as in Table 1. Male palp (Figs 4, 5, 10, 11): Tibial apophysis well presented, pointed. Median apophysis with long apical part curved as hook. Embolus oblique, long, thin. Female paratype: Total length 5.04; prosoma, length 2.52, width 2.16; sternum length 1.26, width 1.08; opisthosoma, length 2.52. All characters as described for male (Figs 6, 7). Leg measurements as in Table 2. Epigyne and vulva (Figs. 8, 9, 12, 13): with well-defined median septum, greatly narrowing posteriorly. Copulatory openings wide, sperm ducts arcuate, spermathecae curved and oblique. Distribution.
