Descriptive notes. This record (see below) of O. haigi represents a southern extension of the species’ range. It was previously known from Curry Co., Oregon and Del Norte Co., California.

Ochrogramma haigi males have the typical modifications in this genus of the mandible (mf, Fig. 32 View Figures 32–37 ) and pregonopodal legs. The first leg telopodites (t1, Fig 32 View Figures 32–37 ) are somewhat reduced, as are those of the second legs (t2, Fig. 32 View Figures 32–37 ) and long gonapophyses (g, Fig. 32 View Figures 32–37 ) curve forward from the second coxae, with prominent vas deferens openings at their bases (vd, Fig. 33 View Figures 32–37 ). At least in this preserved specimen the gonapophyses are carried in front of the male’s “face.” Third leg coxae (cx3, Fig. 34 View Figures 32–37 ) are elongate with prominent terminal lobes (cl, Fig. 34 View Figures 32–37 ). The recumbent setae of the third leg coxal lobes ( Fig. 35 View Figures 32–37 ) have bulbous bases and are striated; the filament of the seta seems to arise beneath the bulbous base.

While the arborescent processes of the anterior angiocoxites are present in O. haigi , they are less extensive than in O. bentona as well as less regular in form ( Fig. 36 View Figures 32–37 ). The gonopods are much more simple and apparently lack both the telopodite and the posterior angiocoxite; the flagellocoxites (f, Fig. 36 View Figures 32–37 ) are tightly appressed to the posterior side of the anterior angiocoxite (aac, Fig. 36 View Figures 32–37 ). The ninth legpair ( Fig. 37 View Figures 32–37 ) has bulbous coxae (c9, Fig. 37 View Figures 32–37 ) with a bifid coxal process (cp, Fig. 37 View Figures 32–37 ) and a small pore (p, Fig. 37 View Figures 32–37 ).
