Male. Black with anterior margin of head orange-brown. Pronotum usually with one or more sordid yellow fascia, sometimes entirely sordid yellow or black. Forewings dark brown, rarely orange-brown, with fine yellow tessellate spots and a subapical greyish spot on outer claval margin, paler specimens with dark brown patches on wing including apex of clavus and adjacent area of corium, darker specimens with claval suture and distal part of outer margin edged with yellow.

Female. Venter black with dorsal area of face orange-brown to pale sorded yellow extended onto pronotum and scutellum. Forewings marked as in male but with subapical greyish spot on outer claval margin less conspicuous.

Male genitalia. Connective with stem twice longer than arms, lateral margins of arms strongly pigmented. Style broad medially, with well developed preapical lobe, apical apophysis fingerlike, curved laterally, apex truncate. Aedeagus with dorsal apodeme tapered to apex in lateral view, expanded laterqally in ventral view; preatrium reduced; shaft short and robust, cylindrical, curved caudo-anteriorly with well developed median ridge ventrally; gonopore apical on ventral surface, large.

Length. Male 4.0– 4.2mm. Female 4.4–4.7mm.

Type material examined. INDIA: Tamil Nadu: lectotype ♂ P. quadrinotata (here designated), ‘Type H.T’, ‘ Penthimia quadrinotata Dist. type’, ‘Kodaikanal’, ‘S. India, T. V. Campbell’,‘S. India, E. A. Butler 1915-60 ’,‘C4’; paralectotype ♂ Penthimia quadrinotata , without determination label but with same data as lectotype (BMNH); lectotype ♀ P. alba replacement name for P. thoracica (here designated): ‘Type H.T’ [red type disc], ‘ Penthimia thoracica Dist. type’, ‘Kodaikanal, S. India, Campbell’, ‘KK 4.14 53 4‘ [hand written on reverse of specimen mount], ‘S. India, E.A. Butler, 1915-60 ’ (BMNH).

Other material examined. INDIA: Tamil Nadu: 1♀, ‘ Kodai Kanal, S . India, T.V. Campbell’, ‘ Brit. Mus. 1926: 171’, ’38 9’, ‘KK 5 16 38 9’; 1♀, same except B.M. 1928-478 ; 1♀, same except ‘KK 6.17 1192 10; 1926-171’ ‘C 50’‘ Penthimia quadrinotata Dist. [hw] C4’; 1♂, 1♀, same except ‘KK 6.17 1192 10’; 1♀, ‘S. India, Madras, Kodaikanal, T.V. Campbell’ ‘KK 5.14 53 4’; 5♂, 2♀, same except ‘KK 6.17’; 1♂, same except 'KK 6‘18’; 2♂, same except ‘KK 5.14’. All BMNH with KK code numbers hand written under specimen card.

Remarks. Both senior and junior synonyms were originally described from an unknown number of specimens (syntypic) with the following data: ‘South India; Kodaikanal (T. V. Campbell)’. Although the specimens from Kodaikanal (BMNH) listed under ‘Other material examined’ are topotypical we cannot be sure of their status (see Material and Methods). This species can be distinguished by the orange-brown fore margin of the head (continued onto remaining vertex, pronotum and scutellum in female) and subapical greyish spot on the outer margin of the clavus. In the male genitalia it has a very distinct aedeagal shaft with well developed median ridge on the ventral margin and by its slender, elongate apophysis of the style. Although the specimens listed under ‘Other material examined’ are topotypical we cannot be sure of their status (see Material and Methods).

This species and P. montana can be distinguished by their relatively pale dorsum with yellow tessellate spots on the forewings but the latter species is larger, has dark brown markings on the vertex and lacks the greyish subapical spot on the outer margin of the clavus.
