Abstract: Ochrogramma haigi Gardner and Shelley, 1989 Ochrogramma haigi Gardner and Shelley 1989: 199. (Fig. 32–37) 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) and pregonopodal legs. The first leg telopodites (t1, Fig 32) are somewhat reduced, as are those of the second legs (t2, Fig. 32) and long gonapophyses (g, Fig. 32) curve forward from the second coxae, with prominent vas deferens openings at their bases (vd, Fig. 33). At least in this preserved specimen the gonapophyses are carried in front of the male’s “face.” Third leg coxae (cx3, Fig. 34) are elongate with prominent terminal lobes (cl, Fig. 34). The recumbent setae of the third leg coxal lobes (Fig. 35) 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). The gonopods are much more simple and apparently lack both the telopodite and the posterior angiocoxite; the flagellocoxites (f, Fig. 36) are tightly appressed to the posterior side of the anterior angiocoxite (aac, Fig. 36). The ninth legpair (Fig. 37) has bulbous coxae (c9, Fig. 37) with a bifid coxal process (cp, Fig. 37) and a small pore (p, Fig. 37).
