Abstract--A detailed morphology of the male and female copulatory organs of the Australian ground spider Hemicloea sundevalli Thorell, 1870 is presented.
Gutierrez and Suriano (1992) added generic characteristics and Kritsky and Gutierrez (1998) proposed an emended diagnosis which characterizes Demidospermus as species having: tandem gonads; counterclockwise coiled male copulatory organ; sinistral vaginal aperture; U-, W-, or V-shaped haptoral bars; subspherical eye granules and a sheath like accessory piece serving as a guide for the male copulatory organ.
For example, the penis is the copulatory organ in males, whereas the clitoris is not necessary for the female to copulate.
She also showed that a petasma, the male copulatory organ, was not formed in parasitized male shrimp.
In treated females, the arrangement of these male copulatory organs was similar but differed in the distance between the penis sheath and the penis: the penis sheath in females was located at the edge of the ctenidium at the mantle skirt, at a distance from the penis.
Testis bilobate, 117-188 (141) long, 94-118 (106) wide; deferent duct long, not overlooped intestinal ceca; seminal vesicle 117-141 (133) long, 61-70 (67) wide, prostatic and accessory reservoirs well developed; sclerotized copulatory organ (Fig.
In aphallic species, two sexual morphs co-occur in natural populations: regular hermaphrodites (euphallic individuals), and aphallic individuals that lack the male copulatory organ (Larambergue 1939).
1983), characterized by the occurrence of two sexual morphs at various ratios in natural populations: regular euphallic individuals and aphallic individuals that lack a male copulatory organ (Larambergue 1939).
Sclerotized male copulatory organ (MCO), tubular, 59 (45-70; n = 10) long, with proximal muscular sheath, and seminal vesicle and prostatic reservoir at the base; accessory piece sclerotized, with irregular shape, at the base of MCO, 29 (18-40, n = 12) long.
Then the males voluntarily remove their copulatory organ and continue in a sterile, and more agile state, to mate-guard the female from competing suitors (Robinson & Robinson 1980).
Aphanoblastella Kritsky, Mendoza-Franco et Scholz, 2000 is mainly characterized for tandem gonads (testis posterior to germarium); male copulatory organ (MCO) nonarticulated with sinuous accessory piece; a sinistral vaginal pore; a nonsclerotized vaginal tube and ventral bar with medial process.
The copulatory organ is a mass of richly vascularized tissue, with intense pigmentation from the base to the extremity of the penis, which is eversible through the cloaca by the action of erector muscles and blood inflow.
