The original description ( Bey-Bienko 1969 ) to be supplemented with the following details: General color light reddish brown, ocellar spots and anteclypeus yellow. Head wide and rounded, slightly longer than wide ( Fig. 6A ); epicranial sutures absent; eyes small; ocellar spots small, but distinct; distance between eyes 1.2 times eye length; distance between antennal sockets 2.1 times of the scape length (about 0.5 mm ); approximate length ratio of 3rd–5th maxillary palpomeres 1.1: 1.0: 1.2. Pronotum campaniform, with caudal margin slightly angulate ( Fig. 6B ). Tegmina reduced to lateral flaps, with traces of venation, marginated laterally and rounded apically ( Fig. 6B ). Wings absent. Mesonotum and metanotum transverse, with weak medial impressions and caudal margins slightly angulate ( Fig. 6B ). Thoracal tergites and abdominal tergites II–VI marginated laterally ( Fig. 6B ). Anterior margin of fore femur armed as in the type A, with 14–15 spines, including 2 apical ones. Fore tibiae not thickened distally. Tibial spines well developed. Tarsi of mid and hind legs broken off. Fore tarsi: Basal tarsomere of fore tarsi (metatarsus) shorter than other segments combined, with 2 more or less equal rows of spines along lower margin; all euplantulae absent or vestigial; claws symmetrical, simple; arolium vestigial. Abdomen without visible glandular specializations; posterolateral angles of tergites attenuate caudally; tergite VI with caudal margin sinusoidally curved ( Fig. 6B ); tergite VII roundly projected caudally, with small median incision ( Fig. 6C ). Anal plate (tergite X) caudally protruded, with distinct median incision on caudal margin ( Fig. 6D ). Cerci broken off. Hypandrium weakly asymmetrical, wide, antero-lateral parts (lateral sternal apodemes or apophyses) elongated; caudal margin angulate between styli ( Fig. 6E ); styli broken off. FIGURE 6.

Male genitalia ( Figs. 3 I–L, 7A–E): left phallomere ( Fig. 3 I–L) with sclerite L4C (L2D) long and narrow, caudally terminating in bulky process ( Fig. 3J, K, b.p .); elongated field densely covered with teeth situated along L4C ( Fig. 3I , K, t.f .); sclerite L3 (L3d) robust, curved in apical part, with directed downward tooth; sclerite L4E, plate-like and curved; sclerite L4F weakly sclerotized, caudally fused with caudal process of sclerite L2; sclerite L4D (L 3v ) large ( Fig. 3I , J ); sclerite L2 (L 2v ) large, widened cranially ( Fig. 3K, L ), terminating in apically curved partly membranous caudal process ( Fig. 3K, L, a.p .); 2 partly sclerotized lobes situated above L2: ventral lobe ( Fig. 3K, v.l .) with short toothed outgrowth at caudo-ventral angle and dorsal lobe ( Fig. 3K, d.l .), dorsally with setal brush; sclerite L1 small. Ventral phallomere L4G (VP) large, as in Fig. 7D, E . Right phallomere complex in shape, as in Fig. 7 A–C; basal sclerite (R2) large; sclerite R1H plate-like, with 2 medially directed spines and narrow cranial outgrowth ( Fig. 7A, c .out.); sclerite R1G large, with single curved apical tooth ( Fig. 7 A–C, a.t. ); sclerite R3 large, plate-like. Measurements (mm). Head length: 4.8, width 4.5, pronotum length 6.5, width 8.9, mesonotum length 3.0, tegmina length 4.8, width 3.2, metanotum length 2.4, width 9.8. Notes . This species was described from the basis of two damaged specimens (male holotype and female paratype ) and provisionally ascribed to the genus Duchailluia (see Bey-Bienko 1969 ). The structure of the male genitalia were not studied. The structure of the male genitalia of N . yemenica is dissimilar to those of the genera Duchailluia and Distylopyga (see above). On the contrary, the structure of the male genitalia of N . yemenica generally resembles N . rhombifolia , the type species of the genus Neostylopyga . There are mutual characters in N . yemenica and N . rhombifolia : left phallomere with sclerite L4C long and narrow, sclerites L4E and L4F separated, sclerite L2 widened cranially, terminating in caudal process, 2 partly sclerotized lobes situated on inner side of phallomere (compare Fig. 3 I–L and Fig. 5 –8 in Anisyutkin 2010 ); right phallomere with sclerite R1H plate-like, with 2 spines and narrow cranial outgrowth (compare Fig. 7 A–C and Fig. 4 in Anisyutkin 2010 ). Taking into consideration the aforesaid, we herewith transfer N . yemenica to the genus Neostylopyga . The sclerites R1H and R1G of Neostylopyga are similar to those of Deropeltis erytrocephala ( Fabricius, 1781 ) , the type species of the genus Deropeltis Burmeister, 1838 , and Afrostylopyga angolensis Anisyutkin, 2014 , the type species of the genus Afrostylopyga Anisyutkin, 2014 , ( Anisyutkin 2014 ).
