Throughout the second situation, i therefore you can expect to differentiate both main patches and ?step 1 area for each area of the membranous muscle ( Profile step 1 and you can Dining table step one)
During the Yards. seminigra queens, i observed one another single couple and you may numerous pairs of melanized patches ( Profile step one and Second Contour S4 ), and in addition we never discovered permanent mating plugs in this species. This new shipping away from multiple spots varied anywhere between step 3 and seven customized section, with different style of plans. On 33 Meters. seminigra specimens assessed, fifteen showed solitary paired spots development, a dozen demonstrated just one coordinated spots in conjunction with a central spot, and you will six specimens exhibited a parallel spot trend ( Supplementary Contour S4 ). Throughout these arrangements, this new central melanized spots matched the new inferred status of the spatha-the new central design on the mating plug ( Shape 2E,I). It’s value discussing that we captured an extra recently mated M. seminigra queen, which was carrying dos mating plugs: 1 is affixed in her own vaginal chamber, whilst the most other is actually on the exterior epidermis out-of the lady instinct, ranging from sterna IV and you can V ( Second Figure S4A ). It recently mated wasn’t totally physogastric, which means that wasn’t found in our very own chief dataset.
Men vaginal tablet and you may vaginal sternum of Meters. fasciculata. Ventral view of vaginal supplement, metasomal sternum S-VIII, and you may metasomal sternum S-IX, once the found inside virgin boys (A). Ventral view of metasomal sternum S-VIII (B) and you will metasomal sternum S-IX (C).

Genital medicine from inside the dorsal view, presenting this new spatha and you may a pair of dick valves (E). Genital tablet in the ventral examine, showing into the sequence, new rotation of the knob regulators, before gonocoxites lateral compressing (F–H). Vaginal product with caused manhood valves and you will gonocoxites compressed sideways, inside dorsal (I) and you can ventral check (J).
Male genital capsule and vaginal sternum regarding M. fasciculata. Ventral view of genital medicine, metasomal sternum S-VIII, and you will metasomal chatrandom mobile site sternum S-IX, once the discover in to the virgin males (A). Ventral look at metasomal sternum S-VIII (B) and you can metasomal sternum S-IX (C). Vaginal tablet in ventral take a look at, demonstrating new gonocoxites and a pair of gonostyli (D). Genital supplement when you look at the dorsal look at, to present brand new spatha and you may a set of manhood valves (E). Genital tablet during the ventral check, proving for the series, the fresh rotation of the dick regulators, in advance of gonocoxites lateral compressing (F–H). Genital product that have brought about dick valves and gonocoxites compacted sideways, from inside the dorsal (I) and you will ventral consider (J).
Functional morphology of one’s men genital product
The male genitalia of Meters. fasciculata keeps step 3 components: dos overlapping metasomal sterna (S-VIII and you will S-IX) and you can a genital capsule ( Shape 2). The latest genital tablet keeps a pair of nearly triangular gonocoxites, in which a couple of much time gonostyli and pair of sharp penis regulators is actually articulated; dorsally there was a slim gonobase and you may an average spatha ( Figure 2E,I). These types of sclerites is actually strongly kept together with her from the a series of walls that allow their 100 % free articulation. All areas was firmly sclerotized, apart from the putatively painful and sensitive setae to the distal 3rd out of gonostyli; and generally are arranged ventrally on the male human body.
The female genitalia out of Meters. fasciculata is positioned into the an effective chamber formed from the tergum and sternum of one’s 6th intestinal part ( Contour step three). The last portion of the female person is membranous, poorly sclerotized, stored because of the pairs off lateral hemitergites (T-VIII and T-IX). Remarkably arising from the latest membranous tail, we come across a pair of quick setose gonostyli, a central bulb (brand new gonopore area), and a pair of narrow, horizontal rami. Between this type of formations as well as the sternum S-VI beneath, just below the newest gonopore urban area, there are large membranous pouches-muscle pouches with just minimal sclerotization-to that male mating connect is actually attached inside mating ( Contour 3A,J) and you can copulatory scratches are located ( Additional Profile S5 ). Membranous pouches try portrayed because of the a light area below the gonopore within the Profile step 3. These membranous structures get inside the Profile step one for everyone types, both in virgin and you can mated queens, even when their cousin size and you will positioning can be looked at in more detail during the Additional Figure S5 .
