Females genitalia of M. fasciculata and you can strategies getting mating connect coupling. (A) Virgin ladies genitalia inside the front evaluate. (B) Men genitalia away from pre-copula male, approaching the feminine genitalia. (C–E) Vaginal medicine, metasomal sterna S-VIII and S-IX. (F) Men genitalia carrying out the latest coupling of your own plug: ventral view of genital product and you may metasomal sternum S-IX projecting from the body of your own male from the an excellent telescopic direction. (G) Men genital pill isolated from male’s human body, with manhood valves brought about, gonostyli up against the exact opposite updates when considering the initial. (H) Metasomal sterna S-VIII and S-IX, where sternum S-IX assumes its unique standing from inside the male’s gut. (I) Mating plug in detail, appearing the brand new horizontal compressing out-of gonocoxites. (J) The fresh new vaginal chamber out of a great plugged women: the new membranous area that features the new mating connect affixed.
From the non-Melipona kinds (F
longipes, S. aff. Postica, and you can P. minima), we observed robust penis valves having intermediary curvature and you will a lower life expectancy spatha ( Figure 1)paring the entire morphology out of cock regulators and you will spatha of M. fasciculata to another learned kinds, we discovered that both Meters. flavolineata and Meters. seminigra possess slim dick regulators which have lowest curvature. Although not, Yards. seminigra has reduced valves than just Meters. flavolineata, and an established spatha when compared with the other Melipona ( Figure step one).
Description off hypothesized plugging tips
The very last updates regarding mating plugs to the mated women matched the latest status of your male’s gut throughout the copulation due to “J” course and you will position not as much as female’s abdomen ( Contour 4C). In most physogastric queens away from Yards. fasciculata, i observed new mating connect attached to the membranous vaginal purse from the dick valves, towards the spatha surface oriented on the feminine ventral piece, placed under the newest gonopore ( Shape 3J). We propose that the fresh new mating connect process is brought about in the event the male genital product was irreversibly protruded away from male’s system, which leads to modified positions of the gonostyli, penis regulators, and you will gonocoxites.
The fresh mating pair of M. fasciculata, predicated on videos number of mating out of an associated kinds. All the way through: (A) men in flight, seeking to standing alone along side women; (B) positioned men, exhibiting pairs regarding foot installing over the woman’s human anatomy; (C) men improving the instinct of your lady; (D) men making the feminine immediately following successful mating, that’s, this new mating plug attachment. In most bits, male wings is portrayed in order to portray its movement through the mating, according to Additional Video S1 .
Brand new mating collection of Yards. fasciculata, according to a video clip listing off mating from a connected varieties. All the way through: (A) male in flight, seeking updates alone along side female; (B) arranged male, indicating pairs off base installing along the woman’s human anatomy; (C) men improving the abdomen of lady; (D) male making the feminine immediately following effective mating, that is, the newest mating connect attachment. Throughout parts, men wings is illustrated so you can portray their direction throughout mating, predicated on Second Films S1 .
According to research by the research between sleeping condition out of genital medications and caused condition away from mating plugs, its functional morphology, as well as in films details to your mating behavior regarding a directly related variety ( Additional Videos S1 ), i recommend that triggering https://besthookupwebsites.org/local-hookup/colorado-springs/ out of mating connect occurs in 5 hypothetical methods ( Numbers step three and 4):
Once immobilizing the feminine human anatomy, the male inserts their metasomal sternum S-VIII within the people tergum T-VI, lifting it ( Contour 4C).
Just like the women genital chamber was started ( Profile 3A), a man gonostyli touches the brand new female’s vaginal part. Immediately following location new sternum S-VIII, a man metasomal sternum S-IX protrudes from the male’s system to the the woman’s genital chamber as well as the genital pill, by a telescopic course ( Contour 3F). The brand new insertion away from men vaginal tablet on the female vaginal chamber is not followed closely by the gonostyli, which move backward inside the processes, remaining beyond your girls vaginal chamber ( Shape 3G).
