Genital useful morphology, hypothesized plugging strategies, and you may mating ranking

Throughout the latter situation, i therefore you may identify both main patches and you may ?step one spot for each region of the membranous tissue ( Profile step one and Dining table step one)

During the M. seminigra queens, i observed both single couples and you can several sets out-of melanized spots ( Profile step one and Additional Profile S4 ), therefore we never found long lasting mating plugs within variety. This new distribution out-of several patches ranged between 3 and eight personalized section, with different style of plans. From the 33 Meters. seminigra specimens assessed, fifteen demonstrated unmarried coordinated spots development, several presented one matched spots in conjunction with a main area, and you can 6 specimens exhibited a simultaneous area development ( Additional Contour S4 ). On these arrangements, the brand new main melanized patches matched the inferred position of your spatha-the newest central construction about mating connect ( Profile 2E,I). It is worth bringing up that people grabbed a supplementary recently mated Yards. seminigra queen, that was carrying dos mating plugs: step one is attached in her own vaginal chamber, although the almost every other try on the exterior body of the lady abdomen, anywhere between sterna IV and you can V ( Second Profile S4A ). It freshly mated wasn’t fully physogastric, which means wasn’t included in the head dataset.

Men genital capsule and genital sternum out of M. fasciculata. Ventral view of vaginal medicine, metasomal sternum S-VIII, and you can metasomal sternum S-IX, once the discover into the virgin guys (A). Ventral look at metasomal sternum S-VIII (B) and you will metasomal sternum S-IX (C). Vaginal product in ventral have a look at, exhibiting the fresh gonocoxites and you can a couple of gonostyli (D). Vaginal capsule inside dorsal have a look at, to provide brand new spatha and you will a couple of cock regulators (E). Vaginal tablet in ventral look at, showing inside the sequence, brand new rotation of your manhood valves, in advance of gonocoxites horizontal compression (F–H). Vaginal pill having caused manhood valves and you can gonocoxites compacted sideways, within the dorsal (I) and you will ventral evaluate (J).

Male genital supplement and genital sternum out of Meters. fasciculata. Ventral view of vaginal tablet, metasomal sternum S-VIII, and you may metasomal sternum S-IX, because discover to the virgin boys (A). Ventral look at metasomal sternum S-VIII (B) and you can metasomal sternum S-IX (C). Vaginal capsule inside the ventral take a look at, indicating the newest gonocoxites and you will a pair of gonostyli (D). Vaginal pill within the dorsal evaluate, presenting the fresh spatha and you may a couple of dick regulators (E). Genital tablet within the ventral consider, showing from inside the series, the newest rotation of your own dick valves, in advance of gonocoxites lateral compressing (F–H). Vaginal medicine with brought about penis valves and you may gonocoxites compressed sideways, into the dorsal (I) and you can ventral look at (J).

Functional morphology of one’s men vaginal pill

A man genitalia off M. fasciculata has step three parts: dos overlapping metasomal sterna (S-VIII and S-IX) and you will a vaginal tablet ( Figure dos). The vaginal product keeps a couple of almost triangular gonocoxites, in which a couple of long gonostyli and the set of piercing cock valves was articulated; dorsally there is certainly a slim gonobase and you may an average spatha ( Figure 2E,I). These sclerites are strongly held together with her from the get redirected here several membranes that enable the 100 % free articulation. All of the parts was highly sclerotized, apart from the newest putatively sensitive setae with the distal third of gonostyli; and they are arranged ventrally regarding male human anatomy.

The female genitalia off M. fasciculata is positioned to the a beneficial chamber designed of the tergum and sternum of your 6th abdominal part ( Shape 3). The past part of the female body is membranous, defectively sclerotized, kept because of the pairs out of lateral hemitergites (T-VIII and you may T-IX). Interestingly due to the brand new membranous rear-end, we come across a set of brief setose gonostyli, a central bulb (the newest gonopore urban area), and you can a pair of slim, lateral rami. Anywhere between such structures while the sternum S-VI beneath, just below the latest gonopore urban area, discover higher membranous pouches-muscle pouches with just minimal sclerotization-to which the male mating connect are attached from inside the mating ( Contour 3A,J) and copulatory scratching can be found ( Second Shape S5 ). Membranous purse are represented of the a white room beneath the gonopore when you look at the Shape step three. These membranous structures are provided inside Shape step 1 for everybody varieties, in both virgin and you can mated queens, even in the event their cousin dimensions and you will direction can be looked at in detail inside Supplementary Profile S5 .
