Supplementary description.
Male
(
Fig. 8
). For full description see
MIYATAKE (1965)
. Measurements. Male (n = 4): EyW: 0.20–0.26 (0.24) mm; EyD: 0.48–0.58 (0.53) mm; BL: 3.17–4.83 (4.13) mm; PL: 0.87–1.33 (1.12) mm; PW: 0.55–0.90 (0.76) mm; EL: 2.30–3.50 (3.01) mm; EW: 0.73–1.15 (1.00) mm. Approximate length ratio of antennomeres (n = 1): 3.1: 1.0: 3.8: 3.8: 4.4: 4.2: 4.2: 4.0: 4.6: 4.0: 6.9. Relative length ratio of rami of antennomeres III–X (n = 1): 1.0: 2.1: 2.4: 2.5: 2.5: 2.4: 2.2: 1.9. EyD/EyW: 2.00–2.40 (2.25); PL/PW: 1.40–1.58 (1.47); EL/EW: 2.78–3.14 (3.02); EL/PL: 2.55–2.98 (2.70); EW/PW: 1.28–1.33 (1.32). Metendosternite with extended furcal arms anterolaterally; furcal laminae distally extended; process extending anteriorly from base of furcal arms. Unguis with basal denticles; pro- and mesotibiae stout, gently widened apically; metatibiae stout, dilated towards basal half, thence slightly curved inwardly.
Pygidium (
Fig. 30
) broadly rounded posteriorly; pygidial struts short, stout. Sternite VIII (
Fig. 36
) weakly pigmented in medial portion; apical margin emarginate in middle. Spicular fork (
Fig. 42
) without lateral plates.
Connecting membrane between tegmen and phallus in fully extended condition (Figs 53–54) vested with fine spines; tegmen shorter than phallus; phallobase cylindrical without phallobasic struts, membranous in ventral view; phallobasic apodeme elongate, rounded at apex; phallus divaricate in apical 1/6, dorsally with median orifice, roundly pointed at apex.
Female
(
Fig. 9
). Measurements (n = 1): EyW:
0.16 mm
; EyD:
0.64 mm
; BL:
4.02 mm
; PL:
1.21 mm
; PW:
0.91 mm
; EL:
2.81 mm
; EW:
1.16 mm
.
Similar to male, but EyD/EyW: 4.00; antennae crenate, about half as long as in males (
Fig. 18
); pronotum rounded on lateral sides; hind tibiae not swollen. Approximate length ratio of antennomeres (n = 1): 2.0: 0.9: 1.6: 1.3: 1.3: 1.3: 1.3: 1.3: 1.4: 1.4: 2.3. Relative width ratio of antennomeres (n = 1): 1.8: 1.5: 1.0: 1.3: 1.8: 2.0: 2.0: 2.0: 2.0: 1.8: 1.8. PL/PW: 1.33; EL/EW: 2.42; EL/PL: 2.32; EW/PW: 1.28. Pygidium (
Fig. 59
) rounded posteriorly; pygidial struts stout. Sternite VIII (
Fig. 60
) rounded posteriorly.
Differential diagnosis.
Paracladiscus atricolor
can be distinguished from
P. choui
sp. nov.
by antennomeres VII–X uniramous in males (
Fig. 17
); females with antennae shorter than total length of head and pronotum combined; punctation of head and pronotum sparse; elytral striae not reaching to apex; tibiae stout in male.
