replace it

<admin>
    <routers>
        <adminhtml>
            <args>
                <modules>
                    <payment before="Mage_Adminhtml">Mymodule_Payment</payment>         
                </modules>
            </args>
        </adminhtml>
    </routers>
</admin>

Answer 2

Issue1: controller file location is wrong

controller/ConciliationController.php

it should be controller s

 ../Mymodule/Payment/controllers/Adminhtml/ConciliationController.php

As you define class Mymodule_Payment_Adminhtml_ConciliationController

Issue2:

<?xml version="1.0" encoding="UTF-8"?>
<config>
   <menu>
        <mymodule_menu translate="title" module="mymodule">
        <title>PagSeguro</title>
        <sort_order>1000</sort_order>
            <children>
                <mymodule_conciliation translate="title" module="mymodule">
                    <title>Conciliation</title>
                    <action>adminhtml/conciliation</action>
                    <sort_order>2000</sort_order>
                </mymodule_conciliation>
                <mymodule_abandoned translate="title" module="mymodule">

    </menu> 
    <acl>
        <resources>
