Diagnosis
Philopteroides holosternus sp. nov. does not appear particularly close to any other species of Philopteroides known from bulbuls. It can be separated from all other species in the genus known from bulbuls by the following characters: male sternal plates III–VI entire, with no lateral accessory sternal plates present ( Fig. 112 View Figs 112–113 ); dorsal sclerite of mesosome with elongated, bifid proximal end ( Fig. 115 View Figs 114–117 ); distal basal apodeme with central ridge that appears to lie dorsal to dorsal sclerite and bear one sensillum on each side ( Fig. 115 View Figs 114–117 ); gonoporal complex unique among species known from bulbuls ( Fig. 116 View Figs 114–117 ).
Etymology
The species name is derived from the Greek words ‘ holos ’ for ‘whole’, and ‘ sternon ’ for ‘chest’, referring to the broad sternal plates and uninterrupted sternal plate of male abdominal segment III.

Description
Both sexes
Head shape as in Fig. 114 View Figs 114–117 , lateral margins of preantennal area shallowly concave, frons deeply concave, with central sclerotization medianly continuous. Dorsal anterior plate as in Fig. 114 View Figs 114–117 . Ventral anterior plate rounded triangular, anterior margin concave. Lobes of ventral carina trapezoidal, widening medianly. Head chaetotaxy as in Fig. 114 View Figs 114–117 . Thoracic and abdominal segments as in Figs 112–113 View Figs 112–113 ; sternal plates broad. Pigmentation differs between sexes, with female much darker than male. Tergopleurites III–VIII with translucent fenestrae around spiracular openings.
Male
Thoracic and abdominal chaetotaxy as in Fig. 112 View Figs 112–113 . Metanotum with 8–9 setae on each side. Base pigmentation light brown, except posterior elongation of dorsal anterior plate, temporal carinae, and proepimera medium brown. Sternal plate II medianly continuous; sternal plates III–VI broad, long, not divided into central and accessory plates. Subgenital plate large, with small irregular accessory plate on segment IX+X. Basal apodeme broad ( Fig. 115 View Figs 114–117 ), narrowing markedly in anterior end, with slightly convex anterior margin. Distal end of basal apodeme with arched, medianly convergent dorsal ridges ( Fig. 115 View Figs 114–117 ). Dorsal thickening of mesosome with bifid anterior extension. Gonopore wide, crescent shaped, distally with wide, blunt nodes ( Fig. 116 View Figs 114–117 ); 1 sensillum on each lobe. Parameres simple ( Fig. 116 View Figs 114–117 ), 2 sensilla on lateral margin of basal paramere, and 2 sensilla on lateral margin in distal half of each paramere. Measurements as in Tables 1–2 View Table 1 View Table 2 .
Female
Thoracic and abdominal chaetotaxy as in Fig. 113 View Figs 112–113 . Metanotum with 7–9 setae on each side. Base pigmentation pale brown, except marginal carina, dorsal anterior plate, preantennal nodi, temporal and temporal marginal carinae, proepimera, prosternal plate, lateral and posterior sections of metanotum, and lateral sections of tergopleurites medium brown. Sternal plate II short but wide ( Fig. 113 View Figs 112–113 ), medianly continuous, and with small lateral accessory plate on each side; sternal plates III–VI wide, with small lateral accessory plates on each side. Subgenital plate as in Fig. 117 View Figs 114–117 . Surface between subgenital plate and vulval margin with faint reticulation. Vulval margin more or less straight ( Fig. 117 View Figs 114–117 ), with 4–5 long and 4–5 short setae on each side. Subvulval plates broad, distal end widely pointed. Measurements as in Tables 1–2 View Table 1 View Table 2 .
