Misidentification
Hoplopholcus scotophilus – Tomić et al. 2000: 35P (specimens from near Velja cave; see S. montenegrinus).
Diagnosis
Distinguished from other species in the ‘northern clade’ (S. absoloni; S. montenegrinus) by bulb measures Aand C (Fig. 158; smaller than other species, no overlap), by bulb measure D (Fig. 159; larger than other species, with little overlap), and by epigynal measure F (Fig. 164; larger than other species, with little overlap); from S. absoloni also by fewer hairs on male cheliceral base (Figs 51, 162; with little overlap), by smaller, weakly sclerotized prolateral sclerite on procursus (arrows in Figs 45–46), by straight procursus (rather than curved toward ventral; Fig. 44), by longer procursus (Fig. 161; with little overlap), by shape of retrolateral bulbal process in retrolateral view (Fig. 47; large notch on ventral side), and by bulb measures Band E (Figs 157, 160; larger than in S. absoloni, with little overlap); from S. montenegrinus also by wider prolateral sclerite on procursus (arrows in Figs 45–46);
Type material
MONTENEGRO – Kotor • 1 ♂, 1 ♀ (without epigynum), 5 juvs, 1 prosoma (juv.?), 1 damaged abdomen (juvenile?), one complete juvenile abdomen, putative syntypes (see Remark below), examined; Pećina u Ivici; 42.5384° N, 18.6207° E [Naumova et al. 2019: 42.569° N, 18.662° E]; date and collector unknown; NMP.
Remark
According to Růžička et al. (2005), the type vial originally contained two labels saying “ Stygopholcus skotophilus sp. n. ” and “Pećina u Ivici, č. III”. This agrees with other labels in Kratochvíl’s handwriting in the NMP Stygopholcus material. Both labels are lost. Růžička et al. (2005) further state that the vial contained “ 1♂ 3♀ (one of them without epigyne) 4 juv. ”, suggesting that there were two epigyna. However, the vial does not contain any epigynum.

Possible record (not examined)
The following record in Kratochvíl (1940) is dubious because he assigned his specimen(s) to S. absoloni, but specimens from the closest caves we examined (Debelin pećina, Kali pećina, Špilja za Gromačkom vlakom) were all unambiguous S. skotophilus. We thus assume that Kratochvíl misidentified his specimen(s) from this cave.
BOSNIA AND HERZEGOVINA • ♂ ♀ (?), material apparently lost; near Grebci, Grabovica pećina; 42.733° N, 18.081° E; 1932(?); J. Kratochvíl leg.(?) [Kratochvíl 1940].
Material assigned tentatively
The material listed here originates from caves around Sedlari in Bosnia and Herzegovina. This material has been studied before by Kratochvíl (1940) and Senglet (2001), and both authors assigned most of the specimens to S. skotophilus (only the female from Medja pećina was assigned to S. absoloni by Kratochvíl 1940). However, both males and females from these caves show some small but consistent differences to S. skotophilus (see section on variation below) so the material is here listed apart to draw attention to this potential separate species (of which no fresh material is available).

BODY. Habitus as in Fig. 2. Ocular area slightly raised. Carapace with deep median pit (Fig. 61) and pair of very shallow indistinct furrows diverging from pit to posterior margin of carapace. Clypeus unmodified. Sternum wider than long (1.50/1.05), unmodified. Abdomen oval, pointed at spinnerets; gonopore with six epiandrous spigots (Fig. 62); ALS with two spigots each (Fig. 69).
CHELICERAE. As in Figs 51–52, with pair of large frontal apophyses set with 2 modified hairs each, with 12 and 13 modified hairs each on frontal face (Figs 63–64); with stridulatory ridges (Fig. 71).
PALPS. As in Figs 6–8; coxa with low retrolateral hump; trochanter barely modified; femur with distinct retrolateral process proximally, with stridulatory pick (modified hair) proximally on prolateral side (Fig. 65); femur-patella joints shifted towards prolateral (arrows in Fig. 6); tibia very large, with two trichobothria; tibia-tarsus joints shifted towards retrolateral (arrows in Fig. 8); tarsus with exposed tarsal organ (Fig. 66); procursus dorsally with curved hairs (distal third curved ‘upwards’), with strong hump on prolateral side; procursus tip with projecting dorsal sclerite, strong hinged ventral sclerite, and membranous central part with brush of hair-like processes on retrolateral side (Figs 67–68), with weakly sclerotized cylindrical process on prolateral side bordering ventral sclerite (arrow in Fig. 45). Genital bulb (Figs 47–50) with basal sclerite connecting to tarsus, small transparent dorsal process, and main sclerite consisting of retrolateral process and dorsal process; retrolateral process with bifid tip, distal part on ventral side thickened and heavily sclerotized; dorsal process with two finger-shaped tips, ventral tip simple, retrolateral tip with additional strong protrusion on ventral side.
LEGS. With short spines ventrally on femur 1 in two rows (Fig. 73), prolateral row ~23 spines, retrolateral row ~28 spines; without curved hairs; few vertical hairs; retrolateral trichobothrium of tibia 1 at 4%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with irregular platelets rather than with distinct pseudosegments.
Male (variation)
Males from most other localities paler, without lateral dark marks on abdomen, with fewer median dark marks (restricted to area above spinnerets), rarely without abdominal marks. Tibia 1 (N = 35): 11.1–14.7 (mean 12.8); tibia 2 (N = 37): 8.1–10.8 (mean 9.6); spines on femur 1: 32–58 (mean 52); modified hairs on each cheliceral basis (N = 74): 9–16 (mean 12.3); modified hairs on each cheliceral apophysis (N = 74): 1–5 (mean 2.7); chelicerae maximum width (N = 36): 0.74–0.86 (mean 0.80); procursus length (N = 37): 1.28–1.48 (mean 1.39); bulbal measures A–E: A (N = 20): 0.28–0.31 (mean 0.30); B (N = 20): 0.08–0.10 (mean 0.09); C (N = 20): 0.13–0.15 (mean 0.14); D (N = 20): 0.28–0.33 (mean 0.31); E (N = 15): 0.82–0.90 (mean 0.87); epiandrous spigots (N = 26): 5–8 (mean 6.1).
Males from near Sedlari differ slightly in bulbal measure Asmaller (0.25–0.28) and bulbal measure B smaller (0.07–0.08); in addition, the smaller wart on the retrolateral bulbal process (arrow in Fig. 48) is more strongly developed.
Female
In general similar to male, but femur 1 without spines, with pair of indistinct processes posteriorly on carapace and pair of opposing poorly visible plates on abdomen; distance between processes/plates: 1.1. Tibia 1 (N = 36): 10.4–14.3 (mean 12.4); tibia 2 (N = 36): 7.2–10.3 (mean 9.0); epigynum width (N = 36): 1.02–1.46 (mean 1.21); epigynum length (N = 36): 0.54–0.68 (mean 0.61); epigynal measure F (N = 36): 0.42–0.58 (mean 0.47). Epigynum anterior plate semicircular, weakly protruding, with weak transversal furrows (Figs 55–58, 76), with internal structures visible in uncleared specimens: round anterior structure, short and indistinct parallel sclerites posteriorly wide apart; posterior plate short but wide. Internal genitalia (Figs 53–54, 147–148) with distinctive ventral arc (Fig. 154; approximately as long as wide), with large pore plates (Fig. 54).
Females from near Sedlari differ in having the parallel sclerites posteriorly in the female internal genitalia closer together (epigynal measure F: 0.32–0.36; Figs 59–60) and slightly more distinct.
Distribution
Known from the southern border area separating Bosnia and Herzegovina from Montenegro, and from the southernmost tip of Croatia (Fig. 168).
