Etymology
Specific name for Miss Emma J. Ingram, for her continued support and encouragement during the writing of this paper.
Description
Based on 20 whole mounts. With features of genus. Body slightly notched at male genital pore. Anterior testis originating posterior to intercaecal field, but anterosinistral to distal termination of right posterior caecum, margins lobed. Posterior testis ovoid to spherical. Cirrussac tearshaped. Internal seminal vesicle spherical, occupying ventral region of cirrussac; ejaculatory duct sinuous; prostatic cells not seen. Ovary obovate, posterior to posterior margin of anterior testis. Oviduct originating at centre of posterior margin of ovary, passing posteriorly dorsally, entering oötype posterodorsally. Vitelline duct forming anterior to anterior margin of cirrussac, passing posteriorly sinuously, dextral to cirrussac, convoluted distally, entering oötype posterodextrally. Oötype ovate. Mehlis’ gland extending anteriorly to posterior margin of cirrussac, extending posteriorly to anterior margin of posterior testis. Uterus extending from oötype, ventral to oviduct. Uterine chamber forming laterally to posterior margin of ovary, straight, narrowing posteriorly, passing dorsally to female genital pore. Vitelline follicles extending anteriorly past intestinal bifurcation, extending posteriorly to posterior margin of uterine chamber, filling intercaecal field, ventral to ovary, oviduct and uterus.
Remarks
This species shows close affinity with the characters differentially diagnostic of the genus Phthinomita and is here identified as a new species in that genus. Phthinomita ingramae n. sp. is immediately distinguished by the combined possession of a body 2317–2983 (2645) long, an anterior testis that is positioned posterior to the intercaecal field but anterosinistral to the distal termination of the right posterior caecum, an anterior testis 5.4–11.3 times longer than wide and 4.9–10.7 times longer than the posterior testis, a tearshaped cirrussac and a uterine chamber that is 174 long on average.
There are in addition, 10–38 base differences (2.8–11.7% sequence divergence) between the ITS2 rDNA sequence of P. ingramae and the remaining Phthinomita species sequenced here. Sequences from Phthinomita ingramae (three replicates) from S. punctatus off Lizard Island differ by 10 bases from those of Phthinomita sp. A (two replicates) from S. virgatus of Ningaloo Reef.
