ETYMOLOGY: This specific name is a patronym in honor of Alison Robyn Mellor, née Bagley, so her maiden name may live on in a manner that reflects her love of nature.

DIAGNOSIS: Males of C. bagleyae resemble those of C. barthorum , with the sternal concavity occupying the whole sternal length (fig. 10) and the epigastric scutum not protruding. In males of C. bagleyae , the cheliceral fangs are shorter, directed medially, and the ventral patch of sternal setae is more rectangular anteriorly (fig. 10).

MALE: Total length 1.11. Carapace 0.50 long, 0.39 wide; abdomen 0.61 long, 0.28 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow. Sternum longer than wide with field of clavate setae covering about 4 = 5 of sternal length and about K of sternal width, bare median band elongate oval, anterior margin rectangular (fig. 10). Cheliceral fangs short, not reaching labium, directed medially, tips not distally widened. Abdomen cylindrical, epigastric scu-

72. Male (PBI_OON 04906), leg I. Scales: 10 m m. tum not protruding. Cymbium-bulb complex ovoid with slim, medially bent embolus incised at base retro- and prolaterally (figs. 84–86).
