In the analyses shown in Figs 2, 4, this taxon appeared within the Xyloryctidae clade but not within the Ptochoryctis clade. In this taxon, M 3 and CuA 1 are stalked in the forewing and in the male genitalia there is a large, basally curved, strongly setose saccular process and the valva has a setose costal ventral membrane. None of these characters are consistent with Ptochoryctis . All of these characters are consistent with the current concept of Metathrinca, as it has been expanded, and this taxon is combined accordingly.</p></div>	https://treatment.plazi.org/id/9450FAC951C25002BF750ECD1DD47AD3	Public Domain	No known copyright restrictions apply.

Accordingly, we combine this taxon as Ptochoryctis corticivora (Meyrick, 1934), comb. nov. and it is transferred from the Depressariidae to the Xyloryctidae . Bradley (1959) correctly notes the superficial similarities between this species and P. chalazopa . However, these two species are 9.6 % pairwise divergent by DNA barcode and they do not form a sub-clade within Ptochoryctis, so there is currently no basis to suggest that they are closely related species.</p></div>	https://treatment.plazi.org/id/0E0A506F5DC15631A662C18753C780ED	Public Domain	No known copyright restrictions apply.

P. flavalbella and P. persicotincta are externally somewhat similar but are brighter in appearance and lack the scattered ochreous scaling and the obscure medial spot present in fresh specimens. The male genitalia of P. eremopa are somewhat similar to those of P. fuscilinea and P. persicotincta . However, in P. fuscilinea the lateral posterior projections of the medial plate of the gnathos are broadly rounded, the emargination of the posterior margin of the gnathos is shallower and the postero-distal thickened membranous extension of the sacculus is more elongate. In P. persicotincta, the posterior apex of the uncus is more rounded and the apical area of the valva is broader.</p><p>Male (Figs 5, 6). Forewing length 7.0–8.0 mm.

Thorax: whitish ochreous, tegulae whitish ochreous; foreleg with femur pale ochreous, tibia and tarsus brown, narrow tibial epiphysis, mid and hindlegs whitish ochreous, long thin whitish scale tufts on femur of mid and hind legs. Forewing broad, costa slightly arched towards termen, otherwise straight, apex broadly pointed, termen angled substantially inwards, tornus obtusely rounded, forewing off white, iridescent, unmarked except for a line of dark brown scales at edge of base of costa to ~ 1 / 5 and scattered scales tipped darker ochreous, a thicker patch of darker tipped scales on dorsum, and, in fresh specimens, darker tipped scales forming an obscure medial spot, cilia with a faint ochreous line at ~ 1 / 3 and a very faint ochreous terminal band.

Type species Deloryctis corticivora Meyrick by original designation. syn. nov.</p><p>Diagnosis.</p><p>Very small to medium sized xylorycytid species. Adults have a strongly tectiform resting posture (Figs 32–34) and the antenna in the male is bipectinate or serrate (Figs 82, 83). The combination in the forewing of R 3 absent and M 3 and CuA 1 separate (or in a single case connate) is diagnostic (Figs 43, 84). In the male genitalia, the thickened membranous postero-distal extension of the sacculus, which is unarticulated, appressed to the valva and without setae or bristles (Figs 101, 104–110), is diagnostic, as is the valva with short sparse setae (Fig. 101). Also, the absence of an articulated saccular process distinguishes the Ptochoryctis from other Xyloryctidae . In addition, in many species, there is a small apical process on the valva. The female genitalia, insofar as they are known, are diagnostic at the species level but there are currently no characters which are diagnostic at the generic level.</p><p>Description.</p><p>Adult. Head: External ocelli absent. Frons with appressed scales, vertex with tufts of long scales projecting laterally from sides of occiput, a ruff of long thin scales on posterior margin of occiput projecting posteriorly, overlaying a collar of broad lamellate scales on anterior margin of prothorax, pointing posteriorly. Pilifers small with short bristle tufts. Maxillary palps small. Labial palps short (&lt;2 × diameter of eye) in anguillaris and chalazopa groups, otherwise long (exceeding 2.5 × diameter of eye), strongly recurved, second segment longer than third. Haustellum with basal portion scaled, usually silver white. Antenna ¾ length of forewing, scape without pecten, pedicel short and broad. Flagellum of male antenna bipectinate or serrate for over ½ to ¾ of length, pectinations / serrations covered in short sensillae, apical portion filiform, dark but with but with white or coloured scaling usually present on at least basal portion and sometimes for most of length. Flagellum of female antenna filiform throughout. Thorax: Thorax with appressed lamellate scales, tegulae short. Tibial spurs 0–2 – 4. Mid and hind legs generally white, hind legs with a thin tuft of long scales. Frenulum of male a single bristle from base of hindwing coupling with retinaculum under a scaled flap of variable length towards the base of Sc on the forewing. Forewing venation: R 1 from just prior to ½ to 2 / 3 discal cell, R 3 absent, R 4 and R 5 stalked, R 4 pre-apical (in one case apical), R 5 post-apical (in three cases apical), M 1, M 2 and M 3 present, M 3 and CuA 1 separate (or in one instance connate), CuP present. Hindwing venation: Rs and M 1 originating from a common stem, M 3 and CuA 1 stalked. Forewing broad, sometimes slightly elongate, costa of forewing straight or gently arched, apex rounded to somewhat pointed, termen often angled substantially inwards, tornus obtuse, cilia long, often very long towards tornus, sometimes producing a dorsal crest (Fig. 34). Forewing generally without line of dark scaling at edge of base of costa, strongly patterned in anguillaris and chalazopa groups and in P. corticivora, unpatterned or weakly patterned otherwise.</p><p>Male genitalia. Uncus short and broad anteriorly, posterior apex variable, anterior margin of dorsal surface usually strongly emarginated. Gnathos with lateral arms, medial plate of gnathos with lateral or medial posterior projection (s) or sometimes a curved band. Tegumen band broad, arched, lateral extensions of tegumen approximately same length as width of tegumen band. Vinculum generally U-shaped, robust, not projecting substantially beyond base of valvae. Saccus small. Base plate of juxta variable, anellus lobes broad, generally extending as far as costal margin of valva. Valva short and broad, ventral surface generally with patch of sparse fine setae in distal half, weak sclerite ventrally, small apical process or nodule often present. Sacculus indistinct with thickened membranous postero-distal extension (visible in preparations towards centre of valva) which is unarticulated, appressed to the valva, and without setae or bristles (Figs 101, 104–110). Aedeagus small and simple, generally slightly curved, often with small posterior projection. Bulbus ejaculatorius slightly longer than aedeagus, not coiled, hood rounded.</p><p>Female genitalia. Papillae anales generally short and broad, apophyses posteriores slightly longer than apophyses anteriores, ostium generally small and circular, sclerotised lamella sometimes present, antrum generally short, lightly sclerotised, ductus bursae membranous, corpus bursae often with single signum.</p><p>Early stages and biology.</p><p>Larvae of the four species for which data is available feed on bark, making webs which incorporate pieces of refuse and bark. They have been found on Hevea ( Euphorbiaceae), Schleichera ( Sapindaceae), Thea (now Camellia) ( Theaceae) and Coffea ( Rubiaceae). There is a further record of a Ptochoryctis sp. on leaves of Phyllanthus pectinatus ( Phyllanthaceae) (Robinson et al. 2001: 345). The larva of P. simbleuta is recorded as feeding on the bark of shoots, eating right through to the cambium and thus killing the branch or plant. P. chalazopa and P. corticivora have been found in association with rubber plantations, the latter recorded as feeding on the outer bark of rubber trees (Bradley, 1959). P. caputanatis and P. sundarbanica have been found in degraded mangrove and secondary forest habitats. Adults of a number of species have been found at light at night.</p><p>Distribution.</p><p>The genus Ptochoryctis is known from India, Bangladesh, Sri Lanka, Myanmar, China (Hong Kong), Thailand, Brunei, Indonesia (Java), Peninsular Malaysia and Malaysian Borneo (see Fig. 113).</p><p>Status and conservation.</p><p>The only verifiable records of described species of this genus post- 2000 are of P. caputanatis and P. sundarbanica . Anon (1958) describes an infestation of larvae of the outer bark of rubber trees in Selangor, Malaysia identified by Bradley (1959) as P. corticivora . Ptochoryctis sp. BOLD: ADJ 0350 has been identified by a neighbor-joining search using P. fuscilinea on BOLD and a small number of images of specimens posted on iNaturalist can be properly identified to this genus or, in one or two cases, to the chalazopa group. P. caputanatis has been found commonly in one restricted area of mangrove forest in the World Wildlife Fund Reserve at Mai Po Marshes in Hong Kong, China and has been sporadically recorded elsewhere in Hong Kong. The quality of the mangrove forest in the Mai Po Marshes, which is clearly a stronghold for this species, has deteriorated and management is needed to improve the quality of the mangrove at this reserve. Further work is required to determine the status and conservation needs of other species.</p><p>Note on Meyrick’s etymology.</p><p>Ptochoryctis Meyrick 1894 – ptochos (Gr.), strictly means a beggar but is sometimes also used to mean poor. In modern Greek it is the legal term for a bankrupt. oryctes (gr.) is one who digs. This is a reference to Meyrick’s recently created family Xyloryctidae, the diggers of wood. The somewhat plain genotype, P. eremopa, is certainly a poor relation to some of the strikingly marked and iconic Australian species which Meyrick placed in his newly established Xyloryctidae (Meyrick, 1890) . It is evident from Meyrick’s endings that he intended its gender to be female.</p></div>	https://treatment.plazi.org/id/796B467563445BDA925420A03753A0B0	Public Domain	No known copyright restrictions apply.

It can be distinguished from the former by the absence of R 3 in the forewing and the latter by the separation of M 3 and CuA 1 in the forewing. It can also be easily distinguished in the male genitalia from these two species by the lack of an articulated saccular process.</p></div>	https://treatment.plazi.org/id/04B91555DE1455DF9965B96E4D19048B	Public Domain	No known copyright restrictions apply.

Sacculus indistinct, postero-distal thickened membranous extension long, broad at base, slightly tapering distally. Aedeagus almost straight with slight posterior projection.</p><p>Female genitalia (Fig. 77). Papillae anales short and broad. Apophyses posteriores slightly longer than apophyses anteriores. Posterior margin of S 8 straight with row of bristles posteriorly. Ostium small, circular. Two thin lateral lamellae running almost perpendicular to ostium for 1 / 3 rd length of sclerotised part of antrum. Antrum narrow, parallel sided, sclerotised section slightly shorter than apophyses posteriores. Ductus bursae thin, membranous. Corpus bursae elongate with large elliptical signum medially.</p><p>Biology and early stages.</p><p>According to Meyrick’s original description, the larva is brick red. It feeds beneath a web covered with refuse and pieces of bark on bark of shoots of tea-plant ( Thea L., now Camellia L.), eating right through to the cambium and thus killing the branch or plant. Eight specimens bred. Found in March and April. It has also been recorded as feeding in branches of Camellia sinensis (Maxwell-Lefroy &amp; Howlett, 1910) .</p><p>Distribution.</p><p>Assam, India.</p><p>Note on Meyrick’s etymology.</p><p>simbleuta Meyrick, 1907 – from simblos (gr.), a beehive. The cloudy, fuscous suffusion referred to by Meyrick in his description together with the fuscous irroration on the forewings resembles a beehive with bees buzzing round it.</p></div>	https://treatment.plazi.org/id/3D8EC2396B285F89BA86819CD96651E5	Public Domain	No known copyright restrictions apply.

Forewing length 8.0 mm, wingspan 17.5 mm. Head: Frons with thick white broad appressed scaling, vertex with tuft of long white scales on posterior margin of occiput pointing forwards and remains of long white scales pointing posteriorly, overlaying remains of collar of broad flat white scales on anterior margin of prothorax. Pilifers with small tufts of bristles; maxillary palps greyish. Labial palps long (2.5 × length of diameter of eye), strongly recurved, principally white, basal segment with a small tuft of golden ochreous scales, second segment substantially longer than third, strongly curved, thickly scaled white with some pale ochreous scaling near base, third segment long, thickly scaled white. Haustellum with silver white scaling on basal portion. Antenna ¾ length of forewing, bipectinate, mainly dark; scape thickly covered in white scales, dorsal surface of basal half of flagellum thickly scaled white, remainder brown, pectinations moderately short, brown, covered with short white sensillae, apical portion filiform. Thorax: pale golden mixed white, tegulae largely missing, white at base; forelegs pale brown, mid legs and hind legs missing. Forewing broad, costa very slightly arched, apex rounded, termen angled inwards, tornus angle almost 90 °; iridescent white, a line of dark fuscous scales at base of costa to ~ 1 / 5, dorsum with fuscous scaling for most of length with a small blotch sub-basally and a larger subquadrate marking post-medially to tornus, a few scattered brown tipped scales post-medially and an interrupted dark brown terminal line, cilia white, very long with a dark brown internal line and remains of a greyish terminal line. Hindwing slightly less broad than forewing, apex rounded, white, scaled brown along veins and with some thin brown scaling between veins, cilia long and white with an indistinct brown line at 1 / 3. Ventrally, forewings dark brown, hindwings white, scaled brown on veins.</p><p>Female. Unknown.</p><p>Pre-genital abdomen. White with white anal tuft. Patches of tergal spines on posterior parts of T 2 – T 7; T 8 and sternites unsclerotised. Apodemes slightly curved, venulae straight.</p><p>Male genitalia (Fig. 65 A, B). Uncus short and broad, medially slightly emarginate, posterior apex bifid, posterior margin with shallow emargination, anterior margin of dorsal surface weakly emarginate. Gnathos with short lateral arms, medial plate with two large rounded, slightly elongate, lateral posterior projections. Tegumen band broad, moderately arched, lateral extensions of tegumen longer than width of tegumen band. Vinculum short and robust, V-shaped, base projecting slightly beyond base of valvae. Saccus short and broad. Juxta with shallow V-shaped basal plate, anellus lobes broad, terminating level with base of costal margin of valva. Valva broad throughout, costal and ventral margins slightly sinuate, apex rounded, fairly sparse fine setae on ventral surface in costal region, extending to apex, long sclerite medially towards ventral margin. Sacculus indistinct, as broad as valva, extending to 1 / 3 valva, thickened postero-distal membranous extension short and broad. Aedeagus slightly curved, almost uniform width.</p><p>Biology and early stages.</p><p>Early stages unknown.
