receptaculum

Hexamermis cochlearius, a parasite found in orthopterans, can be distinguished by having spicules slightly curved with a concavity in the internal face of the tip forming a receptaculum. Six rows of genital papillae; a double row of ventrolateral papillae, the external row with 10 papillae and the internal one with 6; median ventral rows with a single preanal papilla, two single ones situated in each side of the anus and 7 pairs of postanal papillae.

One of the anatomical features of the female that may allow this remarkable reproductive output is her highly specialized pallial oviduct, which includes the seminal receptaculum, the albumen gland (AG), and the capsule gland (CG), all embedded in a single mass of parenchymal tissue (Hayes et al., 2012).

A large flower motif, arranged mostly with four (main) petals around a circular center; the latter being the characteristic feature of this decoration that represents the spiritually important receptaculum of the common lotus flower illustration in Borneo (see below "Significance of these decorations").

Receptaculum with off white reticulate pileus head and stipe; Pileus up to 30 mm in height A- 25 mm in diam.

In cross-section, vascular bundles arranged in three levels can be seen in the receptaculum: approximately 46 peripheral vascular bundles with sclerenchyma sheath, surrounding the sepals and petals (Figure 3h); three central vascular bundles that will form the pistilodium, and six intermediary vascular bundles surrounding the anthers (Figure 3i).
