Intraspecific diversity of Myrmecophilus acervorum (Orthoptera: Myrmecophilidae) indicating an ongoing cryptic speciation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Myrmecophilus acervorum, previously considered a parthenogenetic species widely-distributed in Europe, has been observed to have both sexes in populations inhabiting the central part of the distribution range. Specimens from those heterosexual populations have been found being infected with Wolbachia. New mitochondrial data (COI and 16S markers) revealed the well-supported differentiation of M. acervorum populations inhabiting western Polesie (Poland) and southern Europe. In turn, analyses of EF1α marker support the hypothesis on the unfinished lineage sorting at the nuclear DNA level. Interestingly, we found that parthenogenetic populations inhabiting western Polesie are infected with Wolbachia belonging to supergroup A, while endosymbionts occurring in sexual populations of M. acervorum observed in Romania belong to supergroup B. Furthermore, new and potentially diagnostic characteristics in the external structures of the eyes of M. acervorum were identified. The surface of ommatidia in specimens occurring in southern Europe was smooth. In contrast, the ommatidia surface of individuals collected in Poland was visibly sculptured. To sum up, the significant genetic variability found in the present case, and the differentiating morphological character, are almost certainly effects of cryptic species being present within M. acervorum. This is indicative of ongoing speciation within the populations of this insect, and of simultaneous unfinished lineage sorting at the nuclear DNA level.
