CSS last-child selector: select last-element of specific class, not last child inside of parent?

Question

<div class="commentList">
   <article class="comment " id="com21"></article>
   <article class="comment " id="com20"></article>
   <article class="comment " id="com19"></article>
   <div class="something"> hello </div>
</div>

I want to select #com19 ?

.comment {
    width:470px;
    border-bottom:1px dotted #f0f0f0;
    margin-bottom:10px;
}

.comment:last-child {
    border-bottom:none;
    margin-bottom:0;
}

That does not work as long as I do have another div.something as actual last child in the commentList. Is it possible to use the last-child selector in this case to select the last appearance of article.comment?

:last-child only works when the element in question is the last child of the container, not the last of a specific type of element. For that, you want :last-of-type

As per @BoltClock's comment, this is only checking for the last article element, not the last element with the class of .comment.

body {
  background: black;
}

.comment {
  width: 470px;
  border-bottom: 1px dotted #f0f0f0;
  margin-bottom: 10px;
}

.comment:last-of-type {
  border-bottom: none;
  margin-bottom: 0;
}

<div class="commentList">
  <article class="comment " id="com21"></article>

  <article class="comment " id="com20"></article>

  <article class="comment " id="com19"></article>

  <div class="something"> hello </div>
</div>
