Diagnosis.
Among its relatives within
Pholcus
(see the remark of
P. clavatus
), this species is very similar to
P. huberi
sp. nov.
,
P. songxian
sp. nov.
,
P. parayichengicus
sp. nov.
(all
Henan Province
) and
P. yichengicus
(
Shanxi Province
) in the shapes of the palpal bulb and epigynum, all with a biforked ventral apophysis of trochanter (
Figs. 15I
,
17I
,
33I
,
46I
and
60I
) and a long teat-shaped epigynal apophysis (
Figs. 15A
,
17A
,
33I
,
46A
and
60A
). It can be distinguished from them by the shape of the tip of the procursus and the appendix (
Figs. 15G–I
); also from
P. huberi
sp. nov.
by the branched appendix centrally (
Fig. 15H
), also from
P. songxian
sp. nov.
and
P. parayichengicus
sp. nov.
by the cephalic region with brown central marks (
Fig. 15C
) and also from
P. yichengicus
by the pair of large pore plates (
Fig. 15B
).
Etymology.
The specific name is a patronym in honor of Dr. Mark S. Harvey, a well known arachnologist from
Australia
.
Description.
Male (
holotype
): total body length 4.8: cephalothorax 1.4 long, 1.6 wide; abdomen 3.4 long, 1.4 wide. Leg I: 36.3 (9.3+0.7+9.0+14.9+2.4), tibia II: 8.2, tibia III: 4.4, tibia IV: 7.3; tibia I L/D: 64. Prosoma shape as in
Fig. 15C
. Carapace short, broad and almost circular, ochre, with brown mark broadly connecting to ocular area. Cephalic region raised, with one brown slender central mark, ocular area dark yellow. Clypeus 0.42, ochre, with marks centrally. Distance AME–AME 0.08. Diameter AME 0.09, ALE 0.15, PME 0.14, PLE 0.15. Chelicerae as in
Fig. 15E
, with pair of black apophyses distally, pair of unsclerotized thumb-shaped apophyses proximolaterally and pair of small unsclerotized rounded apophyses proximocentrally. Labium light yellow. Endites gray. Sternum dark gray, with one central marking and three pairs of pale markings along margin as in
Fig.
15F
. Femora, patellae and tibiae ochre, with dark rings, metatarsi and tarsi brown. Abdomen cylindrical, pale ochre, dorsum with several small brown markings as in
Fig. 15C
. Venter pale brown. Palps as in
Figs. 15H and 15I
, bulb with large uncus having numerous teeth along the margin and hoe-shaped appendix. Procursus as in
Fig. 15G
. Tarsal organ capsulate.

Variation.
Tibia I in four other males: 8.4, 8.4, 8.8, 8.9. Body length in four other males 4.4–4.9.
Female: in general very similar to male. Total length of bodies 4.3–5.2. One
paratype
(Mt. Longyuwan), total length 4.5: cephalothorax 1.4 long, 1.5 wide; abdomen 3.1 long, 1.4 wide. Tibia I: 6.7. Distance AME–AME 0.06. Diameter AME 0.08, ALE 0.15, PME 0.13, PLE 0.13. Epigynum roughly dome-shaped as in
Fig. 15A
, with a large necktie-shaped apophysis on the top. Dorsal view as in
Fig. 15B
, with a wavy sclerotized arch anteriorly and a pair of oval pore plates.
