Genital practical morphology, hypothesized plugging strategies, and mating positions

Throughout the second circumstances, i thus you will identify each other main patches and ?step 1 plot on every area of the membranous tissue ( Figure 1 and you will Table step 1)

In the Yards. seminigra queens, i seen one another solitary partners and numerous sets of melanized spots ( Contour step one and you can Supplementary Contour S4 ), and now we never ever located permanent mating plugs within this types. New distribution of numerous patches ranged anywhere between step three and you will eight customized elements, with various brand of preparations. On the 33 M. seminigra specimens analyzed, 15 displayed unmarried paired patches development, 12 displayed an individual coordinated spots in conjunction with a central area, and you may 6 specimens shown a simultaneous patch development ( Supplementary Profile S4 ). Within these arrangements, the new central melanized patches matched up the new inferred condition of one’s spatha-the new central design about mating plug ( Contour 2E,I). It’s worth discussing that people captured an additional recently mated Yards. seminigra king, that was holding dos mating plugs: 1 are connected in her vaginal chamber, even though the most other try onto the external surface away from the woman abdomen, between sterna IV and you will V ( Second Profile S4A ). Which freshly mated wasn’t completely physogastric, for example wasn’t utilized in all of our main dataset.

Men vaginal tablet and you will genital sternum regarding M. fasciculata. Ventral view of genital medicine, metasomal sternum S-VIII, and you can metasomal sternum S-IX, just like the located inside virgin boys (A). Ventral view of metasomal sternum S-VIII (B) and you can metasomal sternum S-IX (C). Genital capsule when you look at the ventral consider, appearing the new gonocoxites and you will a pair of gonostyli (D). Genital product from inside the dorsal have a look at, presenting the newest spatha and you may a couple of dick valves (E). Vaginal medicine into the ventral examine, demonstrating when you look at the series, this new rotation of the dick regulators, ahead of gonocoxites horizontal compressing (F–H). Genital product which have caused dick valves and you may gonocoxites compacted sideways, within the dorsal (I) and ventral look at (J).

Men genital medicine and you may vaginal sternum out-of M. fasciculata. Ventral look at genital tablet, metasomal sternum S-VIII, and you will metasomal sternum S-IX, once the receive into the virgin guys (A). Ventral look at metasomal sternum S-VIII (B) and you may metasomal sternum S-IX (C). Genital product within the ventral check, showing the fresh new gonocoxites and you can a couple of gonostyli (D). Genital capsule inside dorsal take a look at, to present new spatha and you may a couple of dick valves (E). Vaginal product into the ventral consider, demonstrating within the succession, new rotation of the cock regulators, just before gonocoxites horizontal compression (F–H). Vaginal supplement which have triggered knob valves and you will gonocoxites compacted laterally, when you look at the dorsal (I) and ventral examine (J).

Practical morphology of the male genital product

The male genitalia out of Yards. fasciculata features 3 areas: 2 overlapping metasomal sterna (S-VIII and you will S-IX) and a vaginal product ( Shape 2). The newest vaginal product enjoys a pair of almost triangular gonocoxites, where a pair of a lot of time gonostyli as well as the collection of striking knob regulators is actually articulated; dorsally there clearly was a slim gonobase and you may a median spatha ( Figure 2E,I). These sclerites is actually firmly held together with her from the a few walls that allow the 100 % free articulation. All portion was highly sclerotized, apart from brand new putatively sensitive and painful setae into the distal third away from gonostyli; and are generally arranged ventrally throughout the male looks.

The feminine genitalia from Meters. fasciculata is found into the a good chamber molded because of the tergum and you will sternum of sixth abdominal section ( Figure step 3). The final portion of the women person is membranous, poorly sclerotized, stored of the sets off horizontal hemitergites (T-VIII and you will T-IX). Surprisingly as a result of the fresh membranous rear end, we see a couple of quick setose gonostyli, a besthookupwebsites.org local hookup Chilliwack Canada main light bulb (the fresh new gonopore area), and you may a couple of slim, lateral rami. Ranging from these types of structures as well as the sternum S-VI below, underneath the gonopore urban area, discover higher membranous pockets-cells purse with reduced sclerotization-to which the men mating plug are affixed in the mating ( Contour 3A,J) and you will copulatory marks are observed ( Secondary Figure S5 ). Membranous pockets try depicted from the a white space below the gonopore for the Profile step 3. These membranous formations are given inside Figure step one for all variety, both in virgin and mated queens, in the event the cousin proportions and you will orientation can be looked at in more detail in the Secondary Shape S5 .
