Long (CASENT 9029335, HNU), 2 &amp;female;, 7 juvs; [same data] (CASENT 9029334, HNU), 1 ♁, 2 &amp;female;, 1 juv. <b>Etymology.</b> Named for Barb Andrews, who helped guide the 2006 expedition to Kawakarpushan, including a stop at the type locality of this species. <b>Diagnosis.</b> Female similar to <i>O. pullus</i> Bösenberg &amp; Strand, 1906, distinguished from this species by the shape of the posterior lip of the epigynum in dorsal view, convex in <i>O. pullus</i> (Brignoli 1981: fig. 1), concave in <i>O. barbandrewsi</i> (Fig. 3D); by the posterolateral margins in ventral view, nearly straight and flush with abdomen in <i>O. pullus</i> (Chikuni 1989), bowed out from abdomen in <i>O. barbandrewsi</i> (Fig. 3C). Diagnosis of male tentative because few (especially Asian) species have been described from the male and some descriptions are extremely limited in detail. Probably most similar to <i>O. pullus</i> (photographs in Chikuni 1989), distinguished from other species without abdominal humps by details of the shape of the median apophysis and embolic apophysis (Fig. 4E,G). <b>Description.</b> Carapace, sternum, legs orange. Abdomen light gray mottled with dark purple, with dark purple dorsomedian stripe with uneven margins (Fig. 4 A-D). Male palp: Palpal tibia with one trichobothrium. Paracymbium oblong with filiform projection distally (Fig. 5D). Tegulum squamate (Fig. 5E). Median apophysis with apex oriented distodorsally (Fig. 5C). Conductor semitransparent (Fig. 4E). Embolic apophysis long and filiform (typical for genus; Fig. 4G). Vulva: Epigynum with transverse ridge near lip (Fig. 6A), posterolateral margins bowed out from abdomen (Fig. 3C). Spermathecae juxtaposed (Fig. 3D). Copulatory ducts wide at entrance (Fig. 3D). Male (CASENT 9024445): Total length 1.24, carapace 0.56 long, 0.50 wide, clypeus 0.12, sternum 0.31 long, 0.34 wide, coxa IV separated by 2.00 times their width. Posterior median eyes separated by about their diameter. Macrosetae: Leg I: patella d1, tibia p1; Leg II: patella d1; Leg III: patella d1; Leg IV: patella d1. Metatarsal trichobothria: TmI: 0.12; TmII: 0.16; TmIII: 0.11. Leg measurements: see Appendix A. Female (CASENT 9024445): Total length 1.57, carapace 0.51 long, 0.52 wide, clypeus 0.11, sternum 0.34 long, 0.34 wide, coxa IV separated by 1.90 times their width. Posterior median eyes separated by at least their diameter. Macrosetae as in male. Metatarsal trichobothria: TmI: 0.09; TmII: 0.13; TmIII: 0.15. Leg measurements: see Appendix A. Spinnerets (Fig. 6 B-D). <b>Natural History.</b> This species builds a sparse orb web (Fig. 7 A-B).
