Participle Formation
The standard way of listing participles is by aspect, as we do here: progressive, future, future perfect, aorist, and perfect. Then each aspect is divvied into voice: active, middle, and passive, when it differs from the middle. This standard presentation makes sense because we learn participles by aspect, and we think in terms of aspect when analyzing and composing words.
There is, however, another way to think about participles, and that is by their formation: thematic, sigmatic, and athematic. In this way we see morphological patterns more clearly and simplify the available paradigms for forming participles.
Perhaps the most confusion with participle formation concerns whether the masculine nominative singular is marked by lengthening or /ς. For this reason, the charts below list the nominative singular and genitive singular of the masculine, feminine, and neuter. Where paradigms differ (and all the ways they are the same) should be clearer this way.

…are “thematic” and “athematic” the right terms here? That is, where does the perfect active fit?

perfect*
* The formation of the perfect active participle is so peculiar it may be best to consider it separately from the others.
