Fig. 266–269  
 This species is close to H. sabronensis Kimmins from the Cyclops Mts., Papua New Guinea, and here also recorded from Wau in the Morobe Province. Both species have fulvous forewing with pale, spotted reticulation. Hydropsyche carolae is distinguished by its broader segment IX, more excavated intersegmental depression, and the oviform, sclerous endothecal process of the phallic apparatus.   
Male. Body and forewings pale fulvous, with golden pubescence. Forewing membranes with numerous pale hyaline spots, or reticulation of spots, covered by pale pubescence compared to short golden pubescence surrounding the spots. Sternite V with a slightly posteriorly oblique, upward directed flap-like process on both sides anteriorly of basodorsal margin. Maxillary palp formula I-(II, III, IV)-V, segment V shorter than segment III and IV together. Head dorsum fulvous, with 9 fulvous warts. Swollen setal wart present on proepisternum. Pretarsal claws asymmetrical, not laterally flanked by setal bundle. Spur formula 244. Protibiae with posteroapical spur shorter than anteroapical spur.  
Wings. Venation typical for the genus. Forewing crossveins m-cu and cu separate. Sc and R separate before costa. Cu2 and A1 separate before costa. Hind wing Sc and R meeting before costa apically of r by a length equal to length of r; r located apically of s by 0.2 times the length of r. Stem of M and Cu1 situated closely. Crossvein m present, that is median cell closed. Fork 1 present. Forewing length 10.2 mm.  
Male genitalia. Abdominal segment IX fused annularly. Median keel dominating entire dorsum (Fig. 267); long, regularly triangular; base very broad, apex pointed in dorsal view; anterior margin almost regularly arciform, sloping deeper in dorsum than in ventrum; ventrum short; dorsum 2 times longer than ventrum (Fig. 266). Antecosta on each side well developed, narrowing before margins. External groove of antecostal sutures present. Apical lobe on posterolateral margins short, triangular, located immediately above gonocoxites (Fig. 266). Posterior spine row almost continuous, with short interruptions, present on keel slope and apical lobes. Depression between segments IX and X broad, deeply sinuous in lateral view. Body of segment X long; dorsal margin short with dorsal hump at mid-length; ventral margin long, convex, nearly quadrangular in lateral view (Fig. 266). Lateral setose areas (preanal appendages) present centrally on segment X; forming compact, circular setose area fused with another setose area, remnant of reduced apicoventral setose lobe. Apicoventral setose lobe representing setose area at apical margin coalescent with preanal appendages (Fig. 266). Dorsal interlobular gap narrow, shallow, V-shaped in dorsal view (Fig. 267). Apicodorsal setose lobes forming apex of segment X, turning dorsad, obtuse (Fig. 266). Smooth cavity on anterolateral area of segment X less developed. Transverse suture oriented obliquely horizontal, located above setose, preanal appendages on each side of segment X. Longitudinal sutures running below setose surfaces of preanal appendages, meeting transverse sutures at basis. Coxopodites short, robust, dorsal margin slightly sinuous; straight in ventral view, with characteristic incision at dorsal margin (Fig. 266); nearly straight in ventral view (Fig. 268). Harpagones digitiform, parallel-sided, slightly curving dorsad in lateral view, with clavate apex (Fig. 266); straight, slightly broader at basis in ventral view (Fig. 268). Phallic apparatus forming regular tube, with almost right-angled, ventrad curving basal section and straight horizontal section; ventral margin convex before apex (Fig. 269). Endophallus cylindrical, slightly broadening at middle, running through horizontal section, narrowing anterad, ending in gonopore at downwardly curving section of phallotheca. Sclerotized endothecal process long, oviform. Pair of large, rounded, darkly sclerotized phallotremal sclerites present at apex of endophallus. Ventral membranous endothecal process absent.
