Vaginal useful morphology, hypothesized plugging methods, and you may mating positions

Regarding the second case, i therefore could separate one another central patches and you may ?1 plot on every side of the membranous cells ( Shape step one and you will Table step one)

When you look at the Yards. seminigra queens, we seen both solitary couple and numerous sets off melanized patches ( Contour step one and Additional Contour S4 ), and now we never ever located permanent mating plugs within variety. The fresh delivery regarding numerous patches varied anywhere between step 3 and you will 7 individualized components, with different form of arrangements. From the 33 Yards. seminigra specimens reviewed, 15 shown solitary matched up spots development, 12 exhibited an individual matched patches in conjunction with a central spot, and you will 6 specimens demonstrated a simultaneous patch trend ( Second Profile S4 ). Within these plans, the newest main melanized patches matched up the new inferred reputation of your own spatha-the main structure on mating plug ( Contour 2E,I). It’s well worth bringing up that people captured a supplementary newly mated Meters. seminigra king, which was carrying dos mating plugs: 1 are affixed in her own genital chamber, while the most other are onto the exterior body away from the girl instinct, ranging from sterna IV and you will V ( Supplementary Contour S4A ). That it freshly mated wasn't fully physogastric, meaning that was not used in our very own head dataset.

Male genital tablet and you will genital sternum away from Yards. fasciculata. Ventral view of genital medicine, metasomal sternum S-VIII, and you may metasomal sternum S-IX, once the found in to the virgin people (A). Ventral look at metasomal sternum S-VIII (B) and metasomal sternum S-IX (C). Vaginal supplement into the ventral examine, exhibiting this new gonocoxites and you may a couple of gonostyli (D). Vaginal tablet within the dorsal check, to provide the fresh spatha and you will a couple of dick regulators (E). Vaginal pill inside the ventral evaluate, proving into the succession, the brand new rotation of the manhood regulators, in advance of gonocoxites lateral compressing (F–H). Genital pill with triggered penis regulators and you will gonocoxites compressed laterally, during the dorsal (I) and you may ventral look at (J).

Men genital capsule and you may vaginal sternum out of Yards. fasciculata. Ventral look at genital tablet, metasomal sternum S-VIII, and you may metasomal sternum S-IX, because the receive into the virgin guys (A). Ventral look at metasomal sternum S-VIII (B) and you can metasomal sternum S-IX (C). Genital medicine within the ventral consider, indicating the brand new gonocoxites and you will a couple of gonostyli (D). Genital medicine during the dorsal have a look at, to present the fresh spatha and a set of knob valves (E). Genital medicine from inside the ventral have a look at, exhibiting inside sequence, brand new rotation of your dick valves, in advance of gonocoxites horizontal compressing (F–H). Vaginal product having triggered cock regulators and gonocoxites compacted laterally, into the dorsal (I) and you may ventral consider (J).

Practical morphology of one's male vaginal medicine

A man genitalia off Yards. fasciculata has actually step 3 portion: 2 overlapping metasomal sterna (S-VIII and you can S-IX) and a vaginal product ( Shape dos). The fresh new genital medicine has actually a couple of nearly triangular gonocoxites, in which a pair of much time gonostyli and the set of piercing penis valves was articulated; dorsally there was a narrow gonobase and you can an average spatha ( Contour 2E,I). These types of sclerites try strongly kept together with her from the some membranes that allow their free articulation. All the portion are strongly sclerotized, except for the fresh putatively delicate setae to your distal 3rd off gonostyli; and tend to be positioned ventrally regarding men human anatomy.

The feminine genitalia out of M. fasciculata is situated inside good chamber shaped by the tergum and you will sternum of sixth abdominal part ( Figure 3). The last part of the girls body is membranous, poorly sclerotized, held because of the sets away from lateral hemitergites (T-VIII and T-IX). Remarkably as a result of the newest membranous rear-end, we come across a couple of brief setose gonostyli, a main bulb (the fresh new gonopore area), and you will a couple of thin, horizontal rami. Anywhere between these formations together with sternum S-VI beneath, following next the gonopore town, you will find highest membranous pockets-muscle pouches with reduced sclerotization-onto that the male mating connect is affixed into the mating ( Contour 3A,J) and you may copulatory scratches are observed ( Supplementary Contour S5 ). Membranous pockets is actually represented from the a light space below the gonopore in Shape step three. These membranous structures are provided when you look at the Shape 1 for everyone types, in both virgin and you may mated queens, even in the event the cousin dimensions and you will direction can be seen in more detail inside the Additional Profile S5 .
