Diagnosis.--Key characters: Ommatidial size coarse (Fig. 39b); prosternal process between procoxae expanded apically (Fig. 18); mesal antennal spines present (Figs. 8b, 9b); pronotum with impunctate regions present; femoral carinae absent; procoxal cavities closed laterally (Fig. 24); pronotum without transverse sculpturing; pronotum without peripheral pronotal calli; protibial carinae absent; meso- and metatibial carinae present (Fig. 22); femoral apices rounded (Fig. 26); femora gradually enlarged (Fig. 37c); spine on antennomere three acute (Fig. 45a, b); antennomere three about one-half length of pronotum or less (Fig. 46a); antennomere 3+4 about length of pronotum or longer; antennomeres strongly widened at apices or appendiculate (Figs. 13a, 45c); elytra without apicolateral spine (Fig. 41b-e) and with strong sutural spine. Length: 11-19 mm.

Distribution and Diversity.--Southwestern United States to México. Two species.

Discussion.--Neaneflus fell as the sister-group to the rest of the clade of primarily North-American genera in Fig. 56. Neaneflus is very similar in appearance to Aneflomorpha and Aneflus species. It differs from Aneflomorpha in having greatly expanded antennal apices laterally and apically (Aneflomorpha has only slightly expanded antennal apices), and a very short third antennomere (less than half length of pronotum (in Aneflomorpha it is at least three-fourths the length of the pronotum. From Aneflus, it differs in lacking apicolateral elytral spines (strongly developed in most species of Aneflus).
