It is used primarily to mean “to understand” or “to suspect,” so “cachai” is equivalent to “got it?” The most popular meaning in the Hispanic world is “holding any object,” which is close to the literal meaning of the English “to catch.” DIAGNOSIS: Males of O. cachai resemble those of O. pandeazucar by having an additional apophysis in copulatory bulb, but in this species the apophsis is sinuous, whereas it is straight and short in O. cachai . Also, the course of the sperm duct is slightly different in both species (figs. 159A, B, E, F, 168D, F, 173B, 174B), and males of O. pandeazucar have basal conical projections on the endites, absent in O. cachai (compare fig. 164A, C). Females of O. cachai can be distinguished by the short and straight anterior apodemes, epigastric ridges closer to each other, and lumen of anterior receptaculum with three chambers (figs. 161A, B, 170G, 172G, 175F). MALE (PBI_OON 14826): Total length 1.15. Habitus as in figure 155A, B. CEPHALOTHO- RAX (fig. 155C, D): Carapace as in figure 156A– C. Eyes as in figure 156B, D. Sternum as long as wide (figs. 156D, 156E). Chelicerae as in figure 157A–F. Labium rectangular. Endites converging (fig. 164A). ABDOMEN: Dorsum soft portions white, round, setae as in figure 156F. Spinnerets (fig. 157G, H): ALS with one major ampullate gland spigot and three piriform gland spigots seemingly without bases; PMS with one minor ampullate gland spigot; PLS with two aciniform gland spigots. LEGS: Yellow. Leg spination, metatarsi: IV d0-0-1; p0-0-1; r0-0-1. Metartarus I with modified setae on prolateral side (fig. 158B, C); claws, trichobothria, tarsal organs, setae as in other species (figs. 158A, D–F, 160A, B). GENI- TALIA: Cymbium as in figure 159C, tarsal organ as in figure 159D; bulb yellow, tapering apically, with one spine-shaped apophysis; embolus long; sperm duct slightly coiled (figs. 159A, B, E, F, 168D, F, 173B, 174B). FEMALE (PBI_OON 14826): Total length 1.39. Habitus as in figure 155E–G. CEPHALOTHO- RAX: Sternum longer than wide. ABDOMEN: Ovoid. Spinnerets: PMS with two minor ampullate gland spigots (SEM not provided). LEGS: Spination, metatarsi: IV d0-0-1; p0-0-1; r0-0-1. GENITALIA: External pockets placed almost over ridge on epigastric fold, epigastric ridges on median line, comma-shaped (asterisks fig. 170G); internal pockets absent; anterior receptaculum with straight anterior apodemes, lumen formed by three chambers; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 161A, B, 170G, 172G, 175F).
