(Figs 2−14, 19−23)
Diagnosis. The current species of Hemipsocus are similar to H. africanus Enderlein, 1907; H. parallelicus Li, 1996 and H. roseus (Hagen, 1859) in terms of forewings with smoky hyaline and phallosomes. However, Hemipsocus mockfordi sp. nov. differs from the aforementioned species, as well as all other known species of this genus, primarily by the female subgenital plate ending with two apical lobes, which are absent in other species, i.e., posterior margin of subgenital plate broad and medially with narrow indentation and pigmented portion parallel and ‘8’ shaped in H. parallelicus (Fig. 24); posterior margin of subgenital plate broad and medially with broad indentation and two eye shaped sclerites in the anterior portion in H. massulatus (Fig. 25); posterior margin of subgenital plate broad and medially with narrow indentation and two eye-shaped sclerites in the anterior portion in H. africanus (Fig. 26).
Males also differ from the species referred above: the hypandrium is covered with setae on both the anterior and pigmented portions and triangular posterior margin; the epiproct has median denticular fields situated in the anterior portion, and a straight, heavily chitinized paraproct tip. However, it can be differentiated by paraproctal tip circular in H. ornatus, deeply curved in H. parallelicus, H. africanus and H. massulatus (Figs 17, 18, 40, 41). The posterior margin of hypandrium with medially outdent in H. parallelicus and H. africanus, rounded in H. massulatus and triangular in H. ornatus (Fig. 16). The phallosome of present species is similar to the above mentioned species, however endophallic sclerite oval in shape and ½ of the sclerite present outside of the paramere in H. ornatus (Fig. 15).
Description. Male. Color (in 70% ethanol). Head creamy white with pinkish brown markings present as follows: longitudinal bands on the clypeus, the anterior margin of the frons just below the clypeus, two oblique bands on either side of the genae, bands in front of the eyes on either side, and a U-shaped band around the ocelli. Eyes have a transverse black band and a small black spot. Maxillary palpi are yellowish-brown, antennae are ferruginous brown, the thoracic pleural region is creamy yellow with patches of brownish pink. Wings are smoky-hyaline, and veins are dark yellowish with black dots running through them, except for CuP. Legs have a creamy yellowish, claw with a black base and a hyaline tip. Abdomen is creamy white with transverse pinkish brown bands (Figs 2−3).
Morphology. Head: The head is broad and oval-shaped, and its surface is covered with long, shaggy hair. The eyes are hemispherical, and the cornea lacks pubescence. Antennae with a shorter scape and pedicel compared to the flagellar segments. The flagellar segments are long and cylindrical, covered with somewhat close-set long bristly hairs. Maxillary palpi with a stout seta on the distal end of second and third segments (Fig. 5). Lacinia with well-defined inner and outer tines, the outer tine tridentate at the apex (Fig. 6). Thorax: The prothorax is much reduced, and the meso and metathorax is well developed. Forewing: well developed, with rounded apices; with one row of long hairs on the veins except CuP and the margins; hairs on the veins with dark spots; Sc not distinct; subcosta very short; stigmasac well demarcated; pterostigma long and narrow, Rs and M meeting at a point (Fig. 7). Hindwing: hairless margin, Rs-M fused for a distance, R2+3 is short, and slanted; the membrane of the wings is minutely punctate (Fig. 8). Legs: trochanter with setae, femora flattened, tibiae long and cylindrical, tarsi are two-segmented, with the first tarsal segment containing a row of 29 ctenidiobothria, claw with a preapical tooth, a basal setiform process, and a cushion-like pulvillus. Hypandrium: The hypandrium (Fig. 11) is covered with setae on both the anterior and pigmented portions and triangular posterior margin. Phallosome (Fig. 12): the external parameres is open, and narrow phallobase. The endophallus is strongly sclerotized and features a row of 23 teeth in an umbrella-shaped arrangement. The aedeagus is fully membranous, with the inner margin of the phallobase adorned with two narrow sclerites. The epiproct (Fig.13) is sub-triangular and has three long terminal setae, a pair of small lateral setae, and three subapical setae. It possesses well-developed scales at the anterior portion and has a couple of heavily chitinized curving spines in the anterior corners. The paraprocts (Fig. 14) are somewhat tilted with a field of 8 trichobothria on basal rossets and a lack of basal rosset, the paraproctal "horns" are straight and heavily chitinized.
