Melanesobasis corniculata was used as the outgroup in these analyses (see main text and Table 1 for details) but, for the purposes of illustration, only the ingroup (i.e. Nesobasis) is shown here.

Tests of search image and learning in the wild: insights from sexual conflict in damselflies
<p><a name="_Hlk52373699">Search image formation, a proximal mechanism to maintain genetic polymorphisms by negative frequency-dependent selection, has rarely been tested under natural conditions. Females of many non-territorial damselflies resemble either conspecific males or background vegetation. Mate-searching males are assumed to form search images of the majority female type, sexually harassing it at rates higher than expected from its frequency, thus selectively favoring the less common morph. We tested this and how morph coloration and behavior influenced male perception and intersexual encounters by following marked <i>Ischnura elegans</i> and noting their reactions<i> </i>to conspecifics. Contrary to search image formation and associative learning hypotheses, although males </a>encountered the minority, male-like morph more often, sexual harassment and clutch size were similar for both morphs. Prior mating attempts or copulas with morphs did not affect a male's subsequent reaction to them; males rarely attempted matings with immature females or males. Females mated early in the day, reducing the opportunity for males to learn their identity beforehand. Once encountered, the male-like morph was more readily noticed by males than the alternative morph, which, once noticed was more likely to receive mating attempts. Flexible behavior gave morphs considerable control over their apparency to males, influencing intersexual encounters. Results suggested a more subtle proximal mechanism than male learning maintains these color polymorphisms and call for inferences of learning to be validated by behavior of wild receivers and their signalers.</p>

FIGURE 7. Ventral and lateral views of the genital ligula of the four Megaloprepus species. M. caerulatus, M. latipennis and M. brevistigma show significant differences in the inner process of the third segment (s3), M. diaboli sp. nov. constitutes an intermediate position. The scale bar indicates 100 μm.

FIGURE 10 in The damselfly genus Megaloprepus (Odonata: Pseudostigmatidae): Revalidation and delimitation of species-level taxa including the description of one new species
FIGURE 10. Phylogenetic relationships and the character-based barcodes for the mitochondrial CO1 sequence marker gene for the four species of the genus Megaloprepus (M. diaboli, M. latipennis, M. brevistigma and M. caerulatus) from several populations*, the close sister species Mecistogaster linearis, and Coryphagrion grandis as outgroup. A) The phylogeny reconstructed using maximum likelihood in RaxML (1,000 bootstrap replicates), places Megaloprepus brevistigma as a sister clade to the three mostly Central American species: M. diaboli spec. nov, M. latipennis and M. caerulatus. The present tree reconstruction further identifies M. caerulatus and M. latipennis as the closest relatives. B) Selection of single pure character attributes for the investigated species. Hereby a red line stands for A (adenine), blue for T (thymine), green for G (guanine) and yellow for a C (cytosine). Please see File S1 for the complete barcode. *Abbreviations of sample sites are as follows: RBLT = Biosphere Reserve Los Tuxtlas, Mexico; GuLL = National Park Laguna Lachua, Guatemala; GuCSG = Natural Reserve Cerro San Gil, Guatemala; GuRB = Rio Bravo, Guatemala; HnPb = Pico Bonito National Park, Honduras; NiBa = Biological Reserve Indio Maíz, Nicaragua; LS = Biological Research Station La Selva, Costa Rica; CNP = Corcovado National Park, Costa Rica; BCI = Barro Colorado Island, Panama; CO = Pacific Region and West Cariban, Colombia; PhPE = Pampa Hermosa Lodge, Peru.
