Paracloeodes lugoi Randolph & McCafferty 2000

Diagnosis. Male imago. Unknown.

Mature nymph. 1) frons with two convergent keels, fused near clypeus ( Fig. 10 ); 2) labrum with a pair of subapical setae near the middle that are distinguishable from others dorsal setae; 3) one row of five simple setae near distolateral margin of labrum; 4) distal margin of labrum with bifid setae; 5) distolateral margin of labrum with bifid and strong pectinate setae; 6) right mandible incisors cleft; 7) outer incisor of right mandible without vestigial denticle; 8) maxillary palp 1.40× the length of galea-lacinia; 9) apical half of paraglossa without an abrupt decrease in width (rounded condition) ( Figs. 21 and 24 ); 10) angle between inner margin of labial palp segment III and distal margin of segment II greater than 90°; 11) lobe of labial palp segment II relatively angulate ( Fig. 18 ); 12) base of labial palp segment III 0.40× the width of labial palp segment II ( Fig. 18 ); 13) labial palp with length of segment III 0.70× the width of its base ( Fig. 18 ); 14) hind wing pads absent; 15) anterior surface of forefemur with one row of blunt setae near dorsal margin ( Fig. 15 ); 16) medial row of setae on anterior surface of forefemur absent ( Fig. 15 ); 17) anterior surface of forefemur without row of setae near the ventral margin ( Fig. 15 ); 18) fore tarsal claw 0.60× the length of the tarsus, with minute denticles ( Fig. 15 ); 19) abdominal color pattern as in Figure 2 ; 20) length of gills less than 2.0× the subsequent abdominal segment ( Fig. 2 ).
