Clubiona conica View in CoL sp. nov.

( Figures 1D View Figure 1 , 2A–C View Figure 2 , 4A–E View Figure 4 )

Diagnosis

The male of C. conica sp. nov. can be recognized by the long, sickle-shaped retrolateral apophysis on the palpal tibia, and by the very short, spiniform embolus ( Figures 1D View Figure 1 , 4A–C View Figure 4 ). The female is recognized by the thin-walled insemination ducts connected to pyriform spermathecae, and by the membranous bursae with distinct, elongated stalk ( Figures 2A View Figure 2 , 4D,E View Figure 4 ).

Type material

Holotype. ♂, Malaysia, Borneo, Sabah State, Kinabalu National Park, Poring Hot Spring , 500 m, 8 May 1987, D. Burckhardt & I. Löbl leg. (MHNG, 16H).

Paratype. One ♀, same data as for holotype (MHNG, 16H) .

Etymology

The specific epithet is derived from the Greek (κωΝΟϛ = conus = cone-shaped), alluding to a conical base of embolus.

Description

Male (holotype). Total length 5.8; prosoma 3.1 long, 2.8 wide; opisthosoma 2.7 long, 1.3 wide. Prosoma ovoid, pars cephalica broad, almost as wide as carapace width, anterior margin straight, in profile flat; integument smooth; fovea shallow, longitudinal; carapace orange brown, with distinctly brown anterior margin; chelicerae dark brown, with three promarginal and four retromarginal teeth; labium and gnathocoxae brown; sternum pale yellow, bordered with brown margin. Eye sizes and interdistances: AME 0.10, ALE 0.10, PME 0.22, PLE 0.20, AME–AME 0.10, AME–ALE 0.10, PME–PME 0.62, PME–PLE 0.30; MOQ: 0.40 long, 0.30 anterior width, 0.80 posterior width. Legs uniform pale yellow; scopulae on tarsi and metatarsi I–II distinct, in III–IV sparse. Leg formula 4213. Leg measurements: leg I 5.3 (1.6, 0.8, 1.4, 1.1, 0.4); leg II 6.6 (2.0, 0.8, 2.1, 1.2, 0.5); leg III 6.0 (1.5, 1.4, 1.2, 1.4, 0.5); leg IV 7.9 (2.2, 0.7, 2.0, 2.2, 0.8). Opisthosoma ovoid, pale, without colour marking; dorsal scutum lightly sclerotized, located on cardiac region, extending half length of opisthosoma, followed by pair of muscle apodemes.

Palp ( Figures 1D View Figure 1 , 4A–C View Figure 4 ). Palpal tibia short, approximately half length of cymbium; dorsal surface with blunt tubercle; ventro-prolateral surface with broad, triangular, sclerotized VTA; RTA sickle-shaped, greatly elongate, extending anteriorly then curving backwards, tapering towards sharply pointed apex; cymbium with apicodorsal excavation, covered with thick patch of hairs; small, blunt tubercle located on meso-retrolateral side of cymbium; tegulum oblong, apical region weakly sclerotized; sperm duct U-shaped; embolic base dark, conical, situated medially on apical surface of tegulum; embolus spiniform, minute, apex sharply pointed, directed retrolaterad, emerging on apex of embolic base.

Female (paratype). Total length 6.9; prosoma 3.5 long, 3.0 wide; opisthosoma 3.4 long, 1.8 wide. General appearance as in male, but entire body pale yellow, dorsal scutum on opisthosoma absent. Eye sizes and interdistances: AME 0.10, ALE 0.10, PME 0.20, PLE 0.20, AME–AME 0.10, AME–ALE 0.10, PME–PME 0.64, PME–PLE 0.32; MOQ: 0.46 long, 0.30 anterior width, 0.86 posterior width. Legs uniform yellow; scopulae on tarsi and metatarsi I–II distinct, in III–IV sparse. Leg formula 4213. Leg measurements: leg I 5.9 (1.8, 0.8, 1.6, 1.2, 0.5); leg II 7.3 (2.2, 0.8, 2.2, 1.4, 0.7); leg III 6.4 (1.6, 1.6, 1.2, 1.5, 0.5); leg IV 8.4 (2.4, 0.9, 2.0, 2.3, 0.8).

Genitalia ( Figures 2A–C View Figure 2 , 4D,E View Figure 4 ). Epigynal region weakly sclerotized, posteriorly with heavily sclerotized, oval depression situated near epigastric furrow; copulatory orifices circular, separated from one another by their diameter apart, located at centre of epigynal depression; insemination ducts thin-walled, ascending anteriorly, turning outwards and connected to dorsal surface of pyriform spermathecae; spermathecae ventrally with obliquely located falcate projection ( Figures 2B View Figure 2 , 4D View Figure 4 ), apically with digitiform glandular head ( Figures 2C View Figure 2 , 4D,E View Figure 4 ); fertilization ducts ribbon-shaped, distinctly elongate ( Figure 2B,C View Figure 2 ); bursae membranous, with tubular stalk originating on dorsal surface of spermathecae.
