Malamatidia christae spec. nov.

Figs 64-71, 74

Type material. Holotype: female, LAOS: Luang Nam Tha Province: Vieng Phou Kha, Phou Pasat, Tham Pasat Thia , outside cave, forest, leaf litter, by day, sieving, 4 March 2008, P. Jäger leg. ( SMF, L44) .

Etymology. The species is named in honour of Dr Christa Deeleman-Reinhold for her invaluable contribution to the knowledge of the Southeast Asian spider fauna; name in genitive case.

Diagnosis. The longitudinal, posteriorly diverging rim in the central depression of epigyne is diagnostic for Malamatidia spp. ( Deeleman-Reinhold 2001: 191). The female of M. christae spec. nov. is distinguished by the large and posteriorly pointed membranous posterior parts of the spermathecae (Fig. 65) (round and smaller in other Malamatidia spp .).

Description. Female (holotype). PL 1.8, PW 1.2, OL 2.7, OW 0.9. Eye diametres: AME 0.065, ALE 0.10, PME 0.07, PLE 0.09. Eye interdistances: AME-AME 0.05, AME-ALE 0.35, PME-PME 0.19, PME-PLE 0.08, AME-PME 0.09, ALE-PLE 0.055, clypeus AME 0.03, clypeus ALE 0.03. Leg and pedipalp measurements: pedipalp 1.56 (0.50, 0.23, 0.36, -, 0.47); leg I 4.80 (1.34, 0.62, 1.42, 0.90, 0.52); leg II 5.64 (1.60, 0.71, 1.68, 1.05, 0.60); leg III 4.10 (1.19, 0.50, 0.96, 1.01, 0.44); leg IV 6.35 (1.75, 0.63, 1.62, 1.76, 0.59). Leg formula. 4213. Spination: Pedipalp femur: 130, patella 000, tibia 2012, tarsus 10(1)13; Femur I-IV d001; Patella I v020; Tibia I 22220, II v20200, III p010, r010, v110, IV p011, r011, v110; Metatarsus I-II v200, III p001, d212, r001, v202, IV p111, d012, r111, v213. Metatarsal ventral spines I-II long (I 0.66). Chelicerae length 0.6, with 3 anterior and 2 posterior teeth. Prosoma, opisthosoma including spinnerets and anal tubercle elongated as in M. bohorokensis ( Deeleman-Reinhold 2001: fig. 204).

Copulatory organ as in diagnosis. Epigynal field dark grey, round (Fig. 70). Epigyne with transversal rim distinct, short and slightly undulated. Copulatory ducts short and running in a semicircle into the large membranous posterior parts of the internal duct system. Sclerotised anterior parts spherical and with thick walls. No glandular pores recognisable. Fertilisation duct short and dorsad.

Colour in ethanol. Prosoma and opisthosoma pale yellow with spinnerets and labium light grey and distal leg segments darker (Figs 67-69). Screw-coiled spinning glands visible in ventral view (Fig. 68). Colour of the living holotype female was bright yellow with darker distal leg segments (Fig. 74).

Male: unknown.

Natural history. The holotype of M. christae spec. nov. has been collected by sieving leaf litter in a patch of seemingly primary forest.

Distribution. Known only from the type locality (Fig. 71: 2).
