Vaginal practical morphology, hypothesized plugging measures, and you will mating ranks
On the latter case, we ergo could differentiate each other central spots and ?step one plot on every side of the membranous cells ( Figure step one and you will Desk step 1)
For the Meters. seminigra queens, i observed one another solitary couple and multiple pairs out-of melanized patches ( Profile step one and you can Secondary Shape S4 ), and now we never discover permanent mating plugs within this variety. The brand new shipping regarding multiple spots ranged ranging from step three and you may eight custom components, with assorted kind of arrangements. From the 33 Meters. seminigra specimens assessed, 15 presented solitary matched up patches trend, a dozen showed a single paired patches in combination with a central patch, and you can 6 specimens showed a parallel plot development ( Supplementary Profile S4 ). Within these preparations, the newest main melanized spots matched this new inferred updates of your spatha-the central framework throughout the mating connect ( Profile 2E,I). It’s worth discussing we caught an extra newly mated Meters. seminigra king, which had been holding dos mating plugs: step 1 is actually connected inside her vaginal chamber, whilst the almost every other is actually onto the exterior body off their gut, anywhere between sterna IV and you will V ( Second Shape S4A ). Which recently mated was not totally physogastric, and therefore wasn’t used in our very own head dataset.
Male vaginal supplement and genital sternum regarding M. fasciculata. Ventral view of genital supplement, metasomal sternum S-VIII, and you will metasomal sternum S-IX, as discovered inside virgin males (A). Ventral view of metasomal sternum S-VIII (B) and you may metasomal sternum S-IX (C). Genital medicine in ventral have a look at, indicating the gonocoxites and you may a set of gonostyli (D). Vaginal tablet from inside the dorsal have a look at, presenting the new spatha and you will a set of penis valves (E). Vaginal tablet from inside the ventral check, exhibiting for the series, this new rotation of penis valves, in advance of gonocoxites lateral compressing (F–H). Genital pill with caused penis valves and you may gonocoxites compacted sideways, inside dorsal (I) and you may ventral have a look at (J).
Men genital medicine and you may genital sternum out of Yards. fasciculata. Ventral view of vaginal medicine, metasomal sternum S-VIII, and you may metasomal sternum S-IX, once the located into the virgin guys (A). Ventral view of metasomal sternum S-VIII (B) and metasomal sternum S-IX (C). Vaginal pill inside ventral glance at, demonstrating the gonocoxites and you may a pair of gonostyli (D). Vaginal tablet when you look at the dorsal glance at, presenting the fresh spatha and you may a pair of dick regulators (E). Genital product inside ventral view, appearing within the succession, the brand new rotation of your own cock regulators, before gonocoxites horizontal compression (F–H). Vaginal tablet with caused cock valves and you will gonocoxites compacted sideways, inside the dorsal (I) and you may ventral examine (J).
Functional morphology of the male genital capsule
A man genitalia of M. fasciculata enjoys step three components: dos overlapping metasomal sterna (S-VIII and S-IX) and you can a vaginal capsule ( Shape dos). The latest vaginal tablet features a set of nearly triangular gonocoxites, in which a pair of a lot of time gonostyli and the group of striking cock valves are articulated; dorsally discover a thin gonobase and you may an average spatha ( Shape 2E,I). Such sclerites was highly stored with her of the a few walls that allow its totally free articulation. Every areas is highly sclerotized, except for the newest putatively delicate setae towards the distal third out-of gonostyli; and are usually positioned ventrally regarding the men muscles.
The female genitalia off M. fasciculata is situated in to the an excellent chamber molded by the tergum and you can sternum of the 6th abdominal section ( Figure 3). The last part of the female person is membranous, improperly sclerotized, held because of the pairs out-of lateral hemitergites (T-VIII and you can T-IX). Remarkably due to the newest membranous buttocks, we see a pair of quick setose gonostyli, a central light bulb (the new gonopore city), and you can a set of narrow, lateral rami. Ranging from this type of formations and sternum S-VI beneath, below the fresh gonopore city, discover highest membranous dating for seniors price pockets-structure pockets with just minimal sclerotization-to that the men mating connect are affixed for the mating ( Contour 3A,J) and copulatory scratching are observed ( Secondary Contour S5 ). Membranous purse are illustrated of the a white area below the gonopore within the Figure step 3. These types of membranous structures are offered inside the Contour step one for everyone variety, both in virgin and you will mated queens, though its relative dimensions and you can direction can be viewed in detail when you look at the Additional Figure S5 .
