Vaginal functional morphology, hypothesized plugging procedures, and you can mating positions

In the latter instance, we ergo you may distinguish each other main spots and ?step 1 spot for each side of the membranous cells ( Profile step 1 and Table step 1)

During the Yards. seminigra queens, we observed each other solitary partners and you can multiple pairs away from melanized spots ( Profile step one and you may Secondary Shape S4 ), and we never ever discovered long lasting mating plugs within this variety. The newest shipments from numerous spots varied ranging from step three and you may eight custom elements, with various types of preparations. Throughout the 33 M. seminigra specimens reviewed, 15 exhibited unmarried coordinated spots trend, a dozen demonstrated one paired patches in conjunction with a central spot, and you can 6 specimens demonstrated a simultaneous area development ( Secondary Profile S4 ). Within these agreements, new main melanized patches coordinated the newest inferred condition of the spatha-the newest central structure regarding the mating connect ( Shape 2E,I). It is worth bringing up that individuals captured an extra recently mated M. seminigra king, that has been holding 2 mating plugs: step 1 is connected within her genital chamber, whilst the almost every other was on the additional surface out-of the woman gut, ranging from sterna IV and V ( Additional Figure S4A ). It newly mated wasn’t totally physogastric, meaning that wasn’t included in the fundamental dataset.

Male vaginal capsule and you can vaginal sternum regarding Meters. fasciculata. Ventral view of vaginal pill, metasomal sternum S-VIII, and you will metasomal sternum S-IX, as receive in to the virgin boys (A). asian dates login Ventral view of metasomal sternum S-VIII (B) and you may metasomal sternum S-IX (C). Genital pill in the ventral evaluate, showing this new gonocoxites and a pair of gonostyli (D). Vaginal tablet within the dorsal view, to present the fresh spatha and a set of manhood regulators (E). Genital supplement into the ventral view, proving during the succession, the latest rotation of cock regulators, in advance of gonocoxites lateral compressing (F–H). Genital tablet which have brought about cock valves and gonocoxites compacted sideways, in the dorsal (I) and ventral take a look at (J).

Men genital capsule and you may genital sternum from Yards. fasciculata. Ventral view of genital product, metasomal sternum S-VIII, and metasomal sternum S-IX, since found in to the virgin people (A). Ventral look at metasomal sternum S-VIII (B) and metasomal sternum S-IX (C). Vaginal capsule inside ventral look at, indicating new gonocoxites and you may a couple of gonostyli (D). Vaginal pill in dorsal check, to provide the brand new spatha and a set of manhood valves (E). Vaginal capsule within the ventral check, demonstrating within the sequence, the fresh new rotation of your own dick regulators, ahead of gonocoxites horizontal compressing (F–H). Vaginal supplement that have brought about dick valves and you can gonocoxites compressed laterally, in dorsal (I) and you may ventral consider (J).

Practical morphology of one’s male genital pill

The male genitalia away from Meters. fasciculata provides step three components: 2 overlapping metasomal sterna (S-VIII and you may S-IX) and you can a vaginal capsule ( Contour dos). The brand new vaginal tablet provides a couple of almost triangular gonocoxites, where a pair of a lot of time gonostyli while the group of sharp dick regulators is actually articulated; dorsally you will find a narrow gonobase and you can an average spatha ( Shape 2E,I). These sclerites was firmly stored together with her from the several membranes that allow its totally free articulation. Every parts are firmly sclerotized, with the exception of this new putatively painful and sensitive setae with the distal third of gonostyli; and are arranged ventrally throughout the men muscles.

The female genitalia out of M. fasciculata is situated into the good chamber molded by tergum and you may sternum of one’s 6th abdominal sector ( Profile 3). The very last part of the lady body is membranous, badly sclerotized, stored of the pairs out of horizontal hemitergites (T-VIII and you can T-IX). Amazingly as a result of new membranous buttocks, we come across a set of small setose gonostyli, a main bulb (the gonopore urban area), and a pair of slim, horizontal rami. Anywhere between such formations and also the sternum S-VI below, below the fresh gonopore area, you’ll find high membranous pouches-tissues pouches with reduced sclerotization-on to which the male mating plug is attached into the mating ( Shape 3A,J) and you can copulatory scratching are located ( Additional Profile S5 ). Membranous purse is illustrated by the a light room beneath the gonopore inside the Contour 3. This type of membranous formations are provided in the Contour step 1 for everyone types, in virgin and you will mated queens, even though its relative dimensions and you may orientation can be seen in detail inside the Additional Figure S5 .
