Description

Colonies quite variable in shape. Most colonies examined uniplanar, consisting of irregularly dichotomous, non-anastomotic branching (e.g., the holotype, Fig. 5B). The opposite extreme is multilobate and multiplanar colonies (Fig. 5H), composed of thin blades of corallum set in a three dimensional arrangement. Virtually all intergrades in colony shape were observed, including some having both large flattened lobes and slender branches (Fig. 5G). Tallest colony examined (USNM 96252) 21 cm in height with a basal branch diameter of 3.5 cm, but a broken colony having a basal diameter of 4 cm (USNM 1123516) implies an even larger size. Although distal branches often circular in cross section, more often they are somewhat compressed in branching plane. Parasitic spionid polychaete worms often form tubes along axis of branches, Fig. 8 in cross section. Coenosteum reticulate-spinose, the narrow strips only about 60 µm wide and bordered by slits of equal width, each strip bearing irregularly unilinearly arranged spines, altogether producing a porous or rough coenosteal texture. Coenosteum light orange to light pink.
Dactylopore spines isolated or arranged in transverse to oblique rows on distal branches, their dactylotomes facing upward (abcauline), their edges often fusing with edges of adjacent dactylopore spines. On more proximal branches and the basal branch, dactylopore spines fewer in number, and arranged in pseudocyclosystems, short rows, isolated, or as circles around small islands of 2–5 gastropores. Dactylopore spines strongly favor one face of corallum, and are much less common on opposite face. Dactylopore spines relatively small, only about 0.4 mm in maximum height and 0.30-0.35 mm in width, the dactylotome occupying middle third. Small (40–115 µm in diameter) secondary dactylopores flush with coenosteum common. Outer surface of dactylopore spines prominently ridged; inner surface bears a moderately robust dactylostyle (40–50 µm in width, Fig. 10J–K) composed of elements up to 18 µm tall and 7 µm in diameter.
Gastropores circular and flush with coenosteum, 0.15-0.44 mm in diameter, the average about 0.20 mm. Gastropore tube cylindrical, without a ring palisade. Gastrostyles lanceolate, up to 0.55 mm in height, bearing spinose longitudinal, sometimes anastomosing, ridges that themselves bear small spines up to 32 µm long and 8 µm in diameter. Smaller secondary gastropores, lacking gastrostyles, also present, these 0.11–0.19 mm in diameter.
Female ampullae (Fig. 10C) large hemispheres 1.1–1.8 mm in diameter, occurring fairly densely and equally on both corallum faces. Dactylopore spines often occur on female ampullae. Efferent pores rarely observed, but are lateral and up to 0.5 mm in diameter. Male ampullae smaller mounds 0.4–0.7 mm in diameter, clustered, and somewhat irregular in shape. Both types of ampullae porous, like the coenosteum.

Remarks

Errinopora nanneca is one of three species in the genus having a predominantly unilateral arrangement of dactylopore spines in which only one row of laterally fused spines (usually proximal to gastropores) have their dactylotomes facing a gastropore or gastropore row, the other species being Errinopora zarhyncha and Errinopora dichotoma (see Dichotomous Key and Table 1). Errinopora nanneca is distinguished from Errinopora zarhyncha in the account of the latter species, but differs from Errinopora dichotoma in having shorter dactylopore spines and smaller gastropores, uniplanar colonies, and prominently ridged dactylopore spines. Of the 126 specimens examined, 58 are female, 42 male, and 26 indeterminate in gender. The corallum was found to be 100% calcitic according to Cairns and Macintrye (1992)[5].

Distribution

Aleutian Islands from eastern Rat Islands to Islands of Four Mountains, including Petrel Bank; 40-517 m.
