Diagnosis. Sphingius rama sp. nov. can be recognized by the peculiar shape of the median apophysis ( Figs 12– 14 View FIGURES 12 – 16 ) and by the greatly elongate conductor on the male palp ( Figs 12–13 View FIGURES 12 – 16 ), in combination with the enlarged epigynal atrium ( Fig. 15 View FIGURES 12 – 16 ) and the strongly convoluted insemination ducts of female internal genitalia ( Fig. 16 View FIGURES 12 – 16 ).
Etymology. The specific epithet is an eponymous patronym (nominative form of a noun), to commemorate the anniversary of a royal visit of His Majesty King Chulalongkorn, King Rama V to Nam Tok Pliu Waterfall in 1876.
Description. Male (holotype): Total length 3.64. Prosoma 1.68 long, 1.38 wide. Opisthosoma 1.96 long, 1.36 wide. Spination: femora I–III 1 d, IV 1-1 d; tibia I–III 1 -0v, 1p, IV 2- 2v, 1-1r; metatarsi III–IV 1 pv, 2v. Eye size and interdistances: AME 1/2 d of ALE; PME 2/3 d of PLE; AME-AME their d apart; AME-ALE 1/5 d of AME; PME- PME 1/3 d of AME; PME-PLE 1/3 d of AME; PME-PLE 1/2 d of AME; ALE-PLE 4/5 d of AE. MOQ longer than wide, narrower in front than behind.
Prosoma orange-brown; lateral margin serrated, provided with numerous triangular denticles, posterior margin slightly excavated, rebordered; carapace integument punctated. Fovea obsoleted. Sternum orange-brown, distinctly convex, surface smooth and shiny. Chelicerae, labium and gnathocoxae orange-brown. Legs bicolored: coxae ornage-brown, other segments yellowish.
Opisthosoma elongate-ovoid. Dorsal scutum occupying entire length of opisthosoma, orange-brown, distinctly paler posteriorly, covered with black pubescence. Epigastric scutum extending anteriorly, represented by groove collar in dorsal view. Ventral scutum smaller than dorsal one, tightly fused with epigastric scutum, its surface with 2 parallel longitudinal grooves.
Palp ( Figs 12–14 View FIGURES 12 – 16 ): RTA triangular, broad at base, gradually narrowing towards its apex, reaching half length of cymbium. Embolus filiform, elongated; embolic base digitiform, originating posterior medially. Conductor subulated, very long, extending posteriorly. Median apophysis excavated mesoprolaterally, provided with thin, sharply pointed retrolateral process directed mesad and broader, digitiform posterior process directed anteriad.
Female (paratype, MHNG, 3-Sph): Total length 3.74. Prosoma 1.72 long, 1.40 wide. Opisthosoma 2.02 long, 1.46 wide. Spination: femora I–III 1 d, IV 1 -0-1d; tibia I–III 1 -0- 1 v, IV 1-1 -2v, 1-1r; metatarsi III–IV 1 pv, 1-0- 1 v. Eye size and interdistances: AME 1/2 d of ALE; PME 2/3 d of PLE; AME-AME their 1/2 d apart; AME-ALE 1/3 d of AME; PME-PME 1/2 d of AME; PME-PLE 1/3 d of AME; PME-PLE 1/2 d of AME; ALE-PLE 3/4 d of AE. MOQ longer than wide, narrower in front than behind.
General appearance as in male except prosoma slightly wider posteriorly; carapace and sternum smooth; dorsal and ventral scuta on opisthosoma absent; opisthosoma creamy white, sparsely covered with black pubescence.
Genitalia ( Figs 15–16 View FIGURES 12 – 16 ): Epigynal plate weakly sclerotized, occupying almost entire width of opisthosoma. Atrium broad, deep, situated medially, posterior margin indistinct. Copulatory orifices situated on posterior lateral border of epigynal atrium. Insemination ducts greatly elongated, strongly convoluted. Bursae small, spherical, with few pores of ductules, originating on middle portion of insemination ducts. Spermathecae spherical, situated posteriorly. Fertilization ducts falcated.
Natural history. Types of S. rama sp. nov. were collected from humid habitats in lowland semi-evergreen forests.
Distribution. Eastern Thailand ( Fig. 40 View FIGURE 40 ).
