Etymology. Named for Barb Andrews, who helped guide the 2006 expedition to Kawakarpushan, including a stop at the type locality of this species.

Diagnosis. Female similar to O. pullus Bösenberg & Strand, 1906 , distinguished from this species by the shape of the posterior lip of the epigynum in dorsal view, convex in O. pullus ( Brignoli 1981: fig. 1), concave in O. barbandrewsi ( Fig. 3D View Figure 3 ); by the posterolateral margins in ventral view, nearly straight and flush with abdomen in O. pullus ( Chikuni 1989) , bowed out from abdomen in O. barbandrewsi ( Fig. 3C View Figure 3 ).

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 O. pullus (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 View Figure 4 ).

Description. Carapace, sternum, legs orange. Abdomen light gray mottled with dark purple, with dark purple dorsomedian stripe with uneven margins ( Fig. 4 View Figure 4 A-D).

Male palp: Palpal tibia with one trichobothrium. Paracymbium oblong with filiform projection distally ( Fig. 5D View Figure 5 ). Tegulum squamate ( Fig. 5E View Figure 5 ). Median apophysis with apex oriented distodorsally ( Fig. 5C View Figure 5 ). Conductor semitransparent ( Fig. 4E View Figure 4 ). Embolic apophysis long and filiform (typical for genus; Fig. 4G View Figure 4 ).

Vulva: Epigynum with transverse ridge near lip ( Fig. 6A View Figure 6 ), posterolateral margins bowed out from abdomen ( Fig. 3C View Figure 3 ). Spermathecae juxtaposed ( Fig. 3D View Figure 3 ). Copulatory ducts wide at entrance ( Fig. 3D View Figure 3 ).

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 View Figure 6 B-D).
