From the second circumstances, we therefore you’ll distinguish one another central patches and you can ?1 patch for each side of the membranous tissues ( Figure step one and you may Desk step one)
During the M. seminigra queens, we observed one another unmarried partners and you may several sets from melanized spots ( Shape step 1 and you will Supplementary Shape S4 ), so we never ever located long lasting mating plugs within this types. The new shipment off multiple patches varied between step three and you can eight individualized elements, with various brand of arrangements. Throughout the 33 M. seminigra specimens reviewed, fifteen displayed single matched up spots trend, twelve demonstrated one coordinated patches in conjunction with a main patch, and you can 6 specimens showed a simultaneous plot trend ( Supplementary Shape S4 ). Throughout these plans, the brand new main melanized spots matched the newest inferred position of spatha-the fresh central construction throughout the mating plug ( Shape 2E,I). It’s well worth discussing we caught an extra newly mated Meters. seminigra queen, that was carrying 2 mating plugs: step 1 is attached in her vaginal chamber, as the almost every other is actually on the additional skin away from their instinct, anywhere between sterna IV and you may V ( Additional Figure S4A ). It newly mated wasn’t totally physogastric, and thus wasn’t used in all of our head dataset.
Men genital pill and genital sternum away from M. fasciculata. Ventral view of vaginal product, 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 will metasomal sternum S-IX (C). Genital pill during the ventral take a look at, proving the fresh new gonocoxites and you will a set of gonostyli (D). Genital pill for the dorsal view, to provide new spatha https://besthookupwebsites.org/sexfinder-review/ and you can a couple of manhood valves (E). Genital product into the ventral have a look at, proving in succession, brand new rotation of manhood regulators, just before gonocoxites lateral compressing (F–H). Genital tablet with brought about penis valves and you may gonocoxites compacted laterally, during the dorsal (I) and you may ventral take a look at (J).
Male genital medicine and vaginal sternum from Meters. fasciculata. Ventral look at vaginal tablet, metasomal sternum S-VIII, and you may metasomal sternum S-IX, while the found inside virgin boys (A). Ventral view of metasomal sternum S-VIII (B) and you will metasomal sternum S-IX (C). Genital product for the ventral examine, demonstrating this new gonocoxites and a pair of gonostyli (D). Vaginal supplement for the dorsal have a look at, to present the new spatha and you will a couple of manhood regulators (E). Genital pill when you look at the ventral have a look at, demonstrating inside the sequence, this new rotation of your knob valves, in advance of gonocoxites lateral compressing (F–H). Genital product that have triggered penis regulators and you may gonocoxites compacted laterally, from inside the dorsal (I) and you can ventral see (J).
Functional morphology of one’s male vaginal capsule
The male genitalia away from Meters. fasciculata have step 3 components: dos overlapping metasomal sterna (S-VIII and you can S-IX) and you will a genital medicine ( Figure dos). The vaginal capsule features a couple of nearly triangular gonocoxites, in which a couple of a lot of time gonostyli and the collection of sharp penis valves is actually articulated; dorsally there is a thin gonobase and you can a median spatha ( Figure 2E,I). These types of sclerites was firmly kept along with her from the a number of walls that allow the totally free articulation. Most of the components are strongly sclerotized, with the exception of the newest putatively delicate setae towards distal third of gonostyli; and are also positioned ventrally from the male body.
The feminine genitalia away from Yards. fasciculata is located in to the a beneficial chamber molded of the tergum and you may sternum of sixth intestinal portion ( Profile step 3). The very last portion of the people person is membranous, badly sclerotized, held from the pairs from horizontal hemitergites (T-VIII and you can T-IX). Remarkably due to the brand new membranous rear end, we see a pair of small setose gonostyli, a main light bulb (the gonopore city), and you will a pair of slim, lateral rami. Between such formations plus the sternum S-VI underneath, following next the new gonopore town, you can find high membranous purse-structure purse with reduced sclerotization-onto that the men mating plug try attached into the mating ( Contour 3A,J) and you will copulatory scratching can be found ( Secondary Contour S5 ). Membranous purse try illustrated of the a light space below the gonopore inside Shape step 3. This type of membranous structures receive in Profile step one for everyone types, in both virgin and you can mated queens, although its relative dimensions and you can direction can be seen in detail in Additional Profile S5 .
