Diagnosis
This species may be separated from other species of Sarax in Southeast Asia and Oceania by the following combination of characters: lateral eyes very near carapace margin; one dorsal spine on pedipalp tarsus (Fig. 117D); leg IV basitibia with trichobothrium bt situated in distal third; distitibia trichobothrium bc situated closer to sbf than to bf; sc and sf series each with six trichobothria.
The other species of Sarax with one dorsal spine on the pedipalp tibia are S. cochinensis, S. javensis, S. monodenticulatus and S. palau sp. nov., from which S. lembeh sp. nov. can be distinguished by its smaller body size; higher number of trichobothria in the sc and sf series of the leg IV distitibia (six in S. lembeh sp. nov. compared with five in S. cochinensis and S. palau sp. nov.); different number of pseudo-articles on leg IV basitibia (three in S. lembeh sp. nov. compared with four or two in the other species); and the arrangement of spines on the pedipalp femur and patella.
Etymology
Noun in apposition taken from the type locality, Lembeh Island.
Type material
Holotype INDONESIA • ♀; Lembeh Island; [01°25′00.1″ N, 125°13′00.02″ E]; 29 Jun. 1929; Crane, Field Museum Pacific Expedition 1928–1929 leg.; FMNH 3489485.
Description
CARAPACE. Six anterior setae (Fig. 117A); frontal process triangular (Fig. 117C). Median eyes and median ocular tubercle well developed (Fig. 117A, C); pair of setae on median ocular tubercle; lateral eyes well developed, pale, small seta lateral to each lateral ocular triad.
STERNUM. Tritosternum projected anteriorly with typical setation, surpassing base of pedipalp coxae (Fig. 117B); other sternal platelets narrow and projected, with pair of setae anteriorly on plaque and some smaller setae posteriorly; without anterior setae in membranous region and four setae posteriorly.
OPISTHOSOMA. Ventral sacs and ventral sacs cover present.
GENITALIA. Female genital operculum broadly sclerotized between gonopods and posteromedian margin; posterior margin slightly convex, with several setae along margin and on surface. Female gonopod plunger-like, narrower close to apex, tubiform, unsclerotized basally. Male unknown.
CHELICERAE. Retrolateral surface of basal segment without projection opposite to bifid tooth; row of setae on retrolateral surface, basally to dorsally; prolateral surface of basal segment with two parallel, transverse rows of 15 small setae, ventrally to dorsally; claw with four teeth.
PEDIPALPS. Coxae dorsally with round carina; without small setae encircled by carina and with two or three setae on anterior margin. Femur with two distinct setiferous tubercles proximal to dorsal spine 1 (Fig. 117E); primary series with three dorsal spines; three ventral spines (Fig. 117F); setiferous tubercle proximal to ventral spine 1, between spine 1 and proximal margin. Patella with four or five dorsal spines (Fig. 117E); setiferous tubercle distal to dorsal spine I, about one-third length of spine I; three ventral spines decreasing in length (Fig. 117F); setiferous tubercle between ventral spine I and distal margin. Tibia with two dorsal spines, proximal spine two-thirds length of distal spine; ventral spine in distal half of tibia; prominent setiferous tubercle near its base; long setae between spine and distal margin. Tarsus with one dorsal spine, one-fifth length of tarsus (Fig. 117D); ventral row of setae on cleaning organ with 26–27 setae.
LEGS. Tibia of leg I with 23 articles; tarsus I with 41 articles. Leg IV basitibia with three pseudoarticles; trichobothrium bt situated in distal third; distal apex of basitibial pseudo-articles without dark, denticulate projection; distitibia trichobothrium bc situated closer to sbf than to bf; sf and sc series each with six trichobothria. Tarsus with distinct white annulus distally on first article of distitarsus.
