[cittas of] the form sphere.
The consciousness that arises mostly in the “rūpa brahma” world is called “rūpāvacara”. The rūpāvacara citta is basically classified into five according to the five jhāna stages. Then five multiplied by the three types, kusala, vipāka and kriya, comes to 15.
Fundamental Abhidhamma by Dr. Nandamālābhivaṃsa
[cittas of] the supramundane sphere.
Lokuttara is divided twofold: without jhāna and with jhāna. If it arises without jhāna, lokuttara citta is divided into 8. If it arises with jhāna, lokuttara citta is divided into 40.
Magga, the constitution of the Eightfold Noble Path, is classified into four. So, lokuttara citta is classified into four according to magga.
Phala, the effect of magga, is also four, according to magga that is its cause.
path
The magga of sotāpatti completely eradicates the two fetters, wrong view and doubt.
The magga of sakadāgāmi causes reduction of sensual desire and hatred.
The magga of anāgāmi completely eradicates the two fetters, sensual desire and hatred.
The magga of arahatta completely eradicates the five fetters, desire for rūpa jhāna, desire for arūpa jhāna, conceit, mental restlessness, and ignorance.
fruit
The 5 jhānas multiplied by the 4 maggas make 20. The 5 jhānas multiplied by the 4 phalas is 20. Thus, 20 plus 20 becomes 40.
[cittas of] the form sphere.
The consciousness that arises mostly in the arūpa brahma world is called “arūpāvacara”. The arūpāvacara citta is basically classified into four types according to object. Then four multiplied by the three types, namely, kusala, vipāka and kriya, comes to 12.
Fundamental Abhidhamma by Dr. Nandamālābhivaṃsa
The consciousness that has the “infinite space” as its object.
The consciousness that has the “infinite viññāṇa” as its object.
The consciousness that has “non- existence of the first viññāṇa” as its object.
The consciousness that has neither perception nor non-perception based on its object.
Constitution
Each jhāna has associated one or more of 5 Jhānaṅga (jhāna factors) that are particularly characteristic of these jhānas (they don't exclude other factors):
vitakka = initial application, the mental factor that lifts the mind and mental states to its object
vicāra = sustained application, which is sustaining the cultivated [e.g. metta] consciousness continuously onto its object
pīti = joy
sukha = happiness
ekaggatā = one-pointedness
Notes
In the suttas ekaggatā is generally not mentioned as a factor in standard formula for the first jhāna, but is included in MN 43: Mahavedalla Sutta and also MN 111:Anupada Sutta.
It may be viewed as a universal concomitant that brings the mind to a single point.

Actually it's even a prerequisite for jhāna. See MN 19, SN 48.10, MN 117
The first jhāna is accompanied by vitakka, vicāra, pīti, sukha and ekaggatā.
The second jhāna is accompanied by vicāra, pīti, sukha and ekaggatā.
The third jhāna is accompanied by pīti, sukha and ekaggatā.
The fourth jhāna is accompanied by sukha and ekaggatā.
The fifth jhāna is accompanied by upekkhā and ekaggatā.
