Diagnosis:
Basal half of maxillary palpomere 2 yellow. Pronotum with lateral margins almost straight. Elytra dark brown, primary costae yellow in basal 2/3 (
Fig. 4
). Aedeagus with phallobase with short lateroapical thorns, suspensorial arms thin, elongate (
Fig. 11
C-D). Basal 1/6 of phallus is considerably narrower than phallus medially (
Fig. 11A, C
).
Description
: Maxillary palpi brown, basal half of palpomere 2 yellowish. Pronotum yellow with median brown subtriangular patch (
Fig. 4
). Elytra dark brown with primary costae yellow at basal 2/3, forming a striate pattern (
Fig. 4
).

1. Male antennae of
Currhaeus ruschii
sp. nov.
; 2. Terminal maxillary palpi of
C. ruschii
sp. nov.
; 3. Pronotum of
C. striatus
sp. nov.
Scales: 0.5 mm (Figs. 1, 3); 0.25 mm (Fig. 2).
Eye diameter 1.5× longer than interocular distance. Antennomeres 3–5 almost of the same length. Maxillary palpomere 2 twice to 2.8× longer than 3 and 1.3–1.6× longer than 4. Pronotum subpentagonal, lateral margins almost straight, widest at basal margin, median longitudinal carina bifurcating medially forming thin areola at posterior half (
Fig.3
). Prosternum triangular, mesosternum trapezoidal. Elytra 3.8–3.9× longer than humeral width, intercostal intervals with irregular subrectangular cells. Hind femora 3× longer than trochanter length. Aedeagus with basal 2/5–3/5 widened and apex bent almost in right angle to right in dorsal aspect, narrowing before distal spherical expansion (
Fig. 11A, B, D
). Phallobase ladle-shaped, lateroapical thorns short, suspensorial arms thin, elongate, as long as half of phallobase, almost reaching base of phallic expansion.
Junction between base of phallus and phallobase elongate and narrower than phallus width (
Fig. 11A
, C-D). Body length:
6.8–7.2 mm
, humeral width:
1.5–1.6 mm
.
Etymology
: the species name refers to the striate color pattern of elytra.
