Differential diagnosis.
Scymnomorphus
is similar to
Pharellus
Sicard, 1928 and
Paraphellus
Chazeau, 1981. From
Paraphellus
it can be easily separated by club consisting of two or three antennomeres, in contrast to one antennomere in
Paraphellus
. From
Pharellus
it differs in the following characters: maxillary cardo broad, visible externally (very narrow, partially visible in
Pharellus
), submentum distinctly narrower than mentum (submentum and mentum equally broad in
Pharellus
), mentum deeply emarginate apically (mentum truncate apically in
Pharellus
), male genitalia with parameres bearing setae (parameres reduced, without setae in
Pharellus
).
Diagnosis.
Body minute, round to oval, convex, dorsum pubescent (
Figs 1A–L
). Head transverse with clypeus and frons usually produced, sometimes rostrate, clypeus bordered laterally (
Figs 4G, J
). Eyes small, convex, coarsely faceted. Antenna consisting of 10 antennomeres, two (sometimes three) terminal antennomeres forming distinct club (
Figs 2B, J
,
3A
). Maxillary cardo broad and clearly visible externally (
Fig. 4C
). Terminal palpomere elongate-conical (
Figs 3D
,
4G, J
). Submentum distinctly narrower than mentum, mentum deeply emarginate apically (
Figs 3D
,
4C
). Pronotum with line separating anterior corners from pronotal disc. Prosternum strongly reduced, prosternal process reduced to narrow carina (
Fig. 4F
). Mesoventrite short and broad, fused in mid part with metaventrite (
Figs 4F, I
,
5B
). Elytra punctured (
Figs 4A
,
5A
), epipleuron incomplete apically with carina not reaching elytral base (
Fig. 4D
), associated with pits and pores (
Figs 4F, I
). Metaventrite without visible discrimen, usually densely punctured with postcoxal lines descending laterally, associated with pits and pores (
Figs 4F,I
,
5B
). Abdomen with six ventrites in both sexes. Abdominal postcoxal lines incomplete or reaching lateral margin, divided into two lines, usually associated with pits and pores (
Figs 2A, H, I, P
,
3C
). Tarsal formula 4-4- 4. Male genitalia asymmetrical, with parameres reduced, always bearing setae.
