Holocnemus pluchei View in CoL (misidentification) – Roewer 1960: 40 (all specimens except juvenile from Rig- Revan, which is a Pholcus View in CoL ).

Diagnosis

Easily distinguished from geographically close species ( C. maculipes , C. srinagar sp. nov., C. surobi sp. nov.) by male chelicerae with single pair of apophyses in lateral position ( Fig. 543 View Figs 541–549 ) and corresponding pockets on female epigynal plate far apart ( Figs 548 View Figs 541–549 , 551 View Figs 550–554 ); from some very similar species on the Arabian Peninsula (especially C. sahtan sp. nov., C. tiwi sp. nov.) by details of male palp ( Figs 542, 545 View Figs 541–549 ; ventral sclerite at tip of procursus long, much longer than dorsal element; distal bulbal sclerite with distinctive prolateral ridge and single apophysis) and by medially light epigynal plate with distinct semicircular internal median structure ( Fig. 551 View Figs 550–554 ).

Etymology

The name honors Ibn Sina (also known as Avicenna; ~980–1037), a Persian polymath, physician, astronomer, and thinker.

Description

Male (holotype)

MEASUREMENTS. Total length 4.0, carapace width 1.6. Distance PME–PME 55 µm; diameter PME 100 × 130 µm; distance PME–ALE 30 µm; diameter AME 90 µm; distance AME–AME 30 µm. Leg 1: 35.8 (10.2 + 0.7 + 9.6 + 12.9 + 2.4), tibia 2: 6.8, tibia 3: 5.6, tibia 4: 6.4; tibia 1 L/d: 56; femora 1–4 diameters: 0.26, 0.22, 0.21, 0.22.

COLOR (in ethanol). Carapace ochre-yellow, anteriorly in median pit with distinct brown mark; sternum brown with dark brown radial marks; legs ochre-yellow, without darker rings, with small black lines on femora only; abdomen gray, with whitish internal marks, with few and indistinct dorsal marks; ventrally with broken dark band, with indistinct parallel longitudinal marks behind gonopore.

BODY. Habitus similar to C. sahtan sp. nov. (cf. Fig. 391 View Figs 391–398 ). Ocular area slightly raised. Deep thoracic pit and pair of shallow furrows diverging from pit toward posterior margin. Clypeus unmodified, only rim more sclerotized than in female. Sternum wider than long (1.2/0.7), unmodified. Abdomen slightly elongated, dorso-posteriorly angular to conical.

CHELICERAE. As in Figs 543–544 View Figs 541–549 (very similar to C. moqal sp. nov.), with pair of latero-distal apophyses provided with one large modified cone-shaped hair each; distance between tips of modified hairs: 430 µm; lateral stridulatory ridges clearly visible in dissecting microscope.

PALPS. As in Figs 538–540 View Figs 538–540 ; coxa with rounded retrolateral hump; trochanter barely modified; femur distally strongly widened, with rounded ventral protrusion, proximally with prolateral stridulatory pick, with indistinct retrolateral transversal line, without retrolateral proximal process but retrolateral-ventral ridge with some slightly stronger hair-bases; femur-patella joints shifted toward prolateral side; tibiatarsus joints shifted toward retrolateral side; tarsus without macrotrichia; procursus ( Figs 541–542 View Figs 541–549 ) straight, narrowing distally, with low prolateral hump proximally set with numerous long hairs, followed distally by thick ridge, long dorsal hairs mostly straight or weakly curved, procursus tip with long ventral sclerite and two distinctive prolateral sclerites; genital bulb ( Figs 545–547 View Figs 541–549 ) with simple basal sclerite connected to distal (main) sclerite, sperm duct opening not seen; distal sclerite with retrolateral ridge, with distinctive prolateral transversal ridge and small apophysis on ventral semitransparent flap.

LEGS. Femur 1 with single row of ~20 ventral spines; without curved hairs; few vertical hairs; retrolateral trichobothrium of tibia 1 at 3%; prolateral trichobothrium absent on tibia 1, present on other leg tibiae; tarsal pseudosegments indistinct and irregular, only at distal tip ~3–4 regular pseudosegments.

Male (variation)

Tibia 1 in seven males (incl. holotype): 7.2–9.7 (mean 8.8). Some males with distinct dark and whitish marks on abdomen; dark lines sometimes also on leg tibiae.

Female

In general similar to male but without spines on legs, apparently without stridulatory files on chelicerae, and with stridulatory organ consisting of pair of weakly sclerotized but distinct processes posteriorly on carapace and pair of small but distinct light brown plates anteriorly on abdomen. Tibia 1 in 21 females: 6.3–10.3 (mean 8.6). Epigynum as in Figs 550–551 View Figs 550–554 , main epigynal plate semicircular, barely protruding, medially posteriorly light, laterally heavily sclerotized with pair of large but narrow pockets (distance 560 µm); internal median structure visible in uncleared specimens; posterior plate light brown, short but wide. Internal genitalia ( Figs 548–549 View Figs 541–549 , 552–554 View Figs 550–554 ) with large elongate pore plates converging anteriorly, dorsal arc slender, ventral arc with median pouch-like modification.

Distribution

Widely distributed In Central Asia ( Uzbekistan, Tajikistan, Turkmenistan, Kazakhstan, Afghanistan) ( Fig. 352 View Fig ).
