Paratypes, 1 male, 2 females, same data as for holotype (1M, 1F in MNHN; 1 F in PBZT). Diagnosis. Body wide, with costal area biseriate, the areolae large and subquadrate, paranota forming a huge cyst concealing the head and pronotum, including the hood but not the posterior process. Description. Female (N=1): body length, 5.00; width, 3.00; pronotum width, 3.00; Male (N=1): body length, 4.50; width, 2.50; pronotum width, 3.00. Body glabrous. Body and legs light brown. Head, antennae, transverse veinlets on paranota, main hemelytral veins and transverse costal veins, and body beneath dark brown. Head armed with five long, spiny tubercles directed upwards, frontal tubercles separated by twice their base width; antennae long and slender, first antennal segment stouter and twice as long as second, third very long, fourth fusiform and relatively short, antennal segment measurements: I, 0.20; II, 0.10; III, 1.67; IV, 0.47; bucculae short and narrow, meeting in front; rostrum long reaching posterior margin of metasternum. Pronotum with three raised narrow long carinae, median carina continuous from posterior end to hood, uni- seriate, areolae rectangular and large; lateral carinae shorter, ending at base of calli, curved outwardly, uniseriate, areolae as large as on median carina; collar narrow erected on top, forming an upwardly elongate cyst, five areolae high, areolae coarse, polygonal and large, front edge straight, not surpassing collar base, extended posteriorly; paranota strongly developed, extending much higher than hood, reflexed inward as to partly cover pronotum, meeting in front, open at top and behind, nine areolae wide, areolae larger than on carinae and hood, polygonal, with tiny denticles on margins; rostral sulcus narrow, laminae uniseriate, straight and parallel, open posteriorly. Hemelytra longer than abdomen, slightly raised anteriorly and slightly widening posteriorly; costal area irregularly uni- to biseriate, areolae of irregular form and size; subcostal area sloping downward, narrower than costal area, with three row of areolae, two inner rows of large areolae, areolae round and much smaller than on costal area, outer row of areolae smaller than on inner rows; discoidal area oval and elongate, with areolae same size as inner rows of subcostal area, R+M and Cu veins keel-like; sutural area six areolae wide, areolae same size as on discoidal area. Small and round subgenital plate present on ninth female abdominal tergite. Etymology. The species name refers to its size, which is much larger than C. aliwalana Duarte Rodrigues Comments. Caffrocysta previously contained only a single species occurring in South Africa, C. aliwalana (Duarte Rodrigues, 1981). This species differs from C. aliwalana by its general habitus, and particularly by the much higher hood and the paranota, the costal area mostly biseriate which is mostly uniseriate in C. aliwalana. The genus Caffrocysta resembles Calotingis Drake by the general habitus but differs by the much narrow and elevated hood, the much developed paranota and concealing the hood, the wider lateral carinae, the shorter hemelytra. In addition, Calotingis is known only from Australia, Mexico and the USA (Texas).Published as part of Guilbert, Eric, 2020, New species of Tingidae (Insecta: Heteroptera) from Madagascar, pp. 391-404 in Zootaxa 4759 (3) on pages 392-393, DOI: 10.11646/zootaxa.4759.3.5, http://zenodo.org/record/374123

Etymology: The name refers to the smaller hood of this species than those of its congeners. Comments: The two adult specimens were caught in different places, and the female is darker than the male. This species has a small hood, unlike the other Penottus Distant species. This is the first fifth instar of a Penottus species described. The fifth instar was collected in the same place as the female (allotype) but a day after.Published as part of Guilbert, Eric, 2007, Tingidae (Hemiptera: Heteroptera) from Laos: new species and new records, pp. 1-18 in Zootaxa 1442 on pages 9-10, DOI: 10.5281/zenodo.17602

Paranota bi- to triseriate, reflexed, mostly resting on pronotum, but outer margins and parts at opposite humeri elevated, anteriorly armed with very few tubercle-spines; areolae depressed deeply, ridges of areolae covered with many tubercle-hairs (tubercle apically armed with a curved hair), tubercle small (Fig. 7 b). Distance between outer margin of paranotum and lateral carina narrow anteriorly; posteriorly, this distance widening and distinctly wider than that between lateral and median carinae. Distance between lateral and median carinae on posterior pronotal process quadriseriate. Hemelytra long, wider than pronotum, boundary veins raised. Costal area bi- to triseriate, mostly triseriate (Fig. 7 a). Subcostal area narrow, erected, nearly as wide as 1 / 2 of costal area, biseriate. Discoidal area extending backwards, nearly as long as 2 / 3 of hemelytra, nine areolae broad at widest part. Sutural area eight to nine areolae wide at widest part. Hypocostal area narrow, uniseriate, areolae small, and round. Measurements. Males (N = 5) and females (N = 5) respectively. Body length: M, 2.64–2.72 (2.67), F, 2.68– 2.92 (2.82); width: M, 1.18–1.24 (1.22), F, 1.26–1.38 (1.33). Length of pronotum: M, 1.35–1.46 (1.43), F, 1.44– 1.56 (1.50); width: M, 0.96–1.04 (0.99), F, 1.02–1.08 (1.06). Length of hemelytra: M, 1.84–1.92 (1.87), F, 1.88– 2.04 (1.94).

These type specimens were deposited at NKUM. Etymology. The name of the species refers to the fact that it is very similar to its congener Trachypeplus fulgoris (Drake, 1937) Comments. The new species is similar to T. fulgoris (Drake, 1937) in sharing the bi- to triseriate paranota. However, it differs from the latter by its ridges of areolae on its paranota covered with many small tubercle-hairs, and its costal area mostly triseriate at its length (costal area of T. fulgoris biseriate at its length, cf. Figs. 7 a–b, 8 a–b). In addition, Trachypeplus parafulgoris sp. nov. differs from T. guinaicus Drake, 1960 (New Guinea) by its smaller size (2.67–2.82 VS. 3.20 in T. guinaicus), its frontal and median spines slender (Fig. 13) but stout and blunt in T. guinaicus, and its discoidal area wider (nine areolae vs. six to seven areolae in T. guinaicus). The median carina of T. parafulgoris sp. nov. is uniseriate in its length, and the paranota is relatively narrower with two to three areolae broad, whereas T. guinaicus has its median carina partly biseriate and four to five areaolae broad on paranota (based on the type deposited in National Museum of Natural History (NMNH), Washington D.C., observed by the co-author E. Guilbert).Published as part of Dang, Kai, Guilbert, Eric & Bu, Wenjun, 2013, New species and records of the genus Trachypeplus Horváth (Hemiptera: Tingidae) from China, pp. 531-550 in Zootaxa 3669 (4) on pages 536-538, DOI: 10.11646/zootaxa.3669.4.7, http://zenodo.org/record/24784
