FIGURE 26. Parasmittina indigenella sp. nov. : A, portion of colony; B, several zooids with ooecia; C, close-up of distal end of zooid showing avicularia, peristome and oecium; D, close-up of orifice showing bases of six orificial spines; E, primary orifice with broad, low lyrula; F, avicularium with solid cross bar. Scale bars: A, 1 mm; B, 0.5 mm; C, D, 0.1 mm; E, 0.2 mm; F, 0.05 mm. Material examined. Holotype : VMNH no. 70639. Paratype : USNM no. 1283252. Etymology. Latin, indiginus , born in a country, native, plus the diminutive suffix - ella , i.e. the little native Parasmittina . Diagnosis. Parasmittina with a low broad lyrula, 5–6 orificial spines, an ooecium with a larger inner area with scattered, raised pores, a narrow outer layer, and one or two triangular frontal avicularia, oriented toward the orifice peristome. Description. Colony encrusting ( Fig. 26 A). Zooids rectangular to oval in shape with a thickly calcified lowridged frontal shield. Small, but closely spaced marginal areolae forming a double row of pores ( Fig. 26 C). Primary orifice with low, broad lyrula, almost occupying entire proximal rim; rounded lateral and distal rim smooth ( Fig. 26 D). Secondary orifice raised on low peristome ( Fig. 26 C); distal part of peristome bearing 5–6 jointed hollow spines; proximal half with U-shaped pseudosinus ( Fig. 26 D). One or two elongate triangular avicularia near zooid margins, angled toward peristome. Ooecia globular, embedded, with narrow imperforate ectooecium and large entooecium with scattered raised pseudopores ( Fig. 26 B, C). Remarks. This species is similar to species of Parkermavella , except for the presence of a lyrula. It is similar in size and morphology to the Barbadian species Parkermavella salebrosa Winston & Woollacott, 2009 , which, however, lacks a lyrula, has more orificial spines (6–7) and small oval avicularia. Distribution. Florida, Oculina banks.
