CENTROMERIA INFLATA SP. NOV.

FIGS 2D , 17A – I

Type specimens. Holotype: ♂, Philippines, Camarines Sur, Mount Isarog , 500 – 1200 m a.s.l., 27.iv.1963, H.M. Torrevillas ( BPBM).

Paratype: Philippines, 1♂, Camarines Sur, Mount Iriga , 500 – 600 m a.s.l., 1.iv.1962, H.M. Torrevillas ( BPBM) .

Etymology. This new species name is derived from the Latin ‘ inflatus ’, referring to its distinctly apically inflated and bulbous frons.

Diagnosis. This species can be distinguished from other known Centromeria species by its cephalic process being inflated and bulbous apically.

Description. BL, ♂ 17.8 – 18.6 mm; HL, 2.7 – 2.9 mm; HW, 1.8 – 1.9 mm; TL, 13.4 – 14.0 mm.

Cephalic process in lateral view elongate, distinctly longer than length from anterior margins of eyes to posterior margin of vertex; moderately upturned and ascending at about 30° ( Fig. 17B ); apex not narrowed in front of eyes ( Fig. 17A ) and differing from other Centromeria species because of apex of frons inflated ( Fig. 17C ). Vertex relatively broad, posterior margin nearly as wide as transverse diameter of eyes; in dorsal view ratio of length to width between eyes about 3.3: 1 ( Fig. 17A ); lateral carinae moderately constricted and moderately upturned in front of eyes ( Fig. 17A ). Frons ( Fig. 17C ) with apex distinctly inflated and bulbous, clearly visible in dorsal view ( Fig. 17A ). Fore femora with a distinct minute spine near apex; hind tibiae with seven or eight lateral spines; hind tarsomeres I with ten apical teeth and tarsomeres II with between ten and 12 apical teeth.

Male genitalia with pygofer in lateral view broad and high, with ratio of ventral to dorsal width about 2.0: 1; posterior margin with a small, narrow, and straight process near middle, apex obtuse ( Fig. 17E ). Gonostyles ( Fig. 17E ) with upper process large and stout, slightly acute apically. Aedeagus ( Fig. 17G – I ) moderately large, with one pair of long and stout endosomal processes extended posteriorly and curved dorsally ( Fig. 17H ); phallobase sclerotized and pigmented at base, membranous and inflated apically, with two pairs of ventrolateral lobes covered with numerous small and short spines ( Fig. 17H, I ), and one pair of ventral lobes narrow and long, directed posteriorly, without spines ( Fig. 17I ). Segment X in dorsal view large and broad, nearly rounded, with ratio of length to width near middle about 1.3: 1 ( Fig. 17D ).

Distribution. Philippines (Camarines Sur).

CENTROMERIA INSPINATA HAUPT, 1917

FIGS 2E , 18A – C

Centromeria inspinata Haupt, 1917: 307 ; Metcalf, 1946: 37.

Material examined. Indonesia, 1♀, Celebes [Sulawesi], Paleleh , 15.xii.1930, G. Heinrich ; 1♀, Celebes [Sulawesi], Ile-ile , 500 – 800 m a.s.l., Anf. xii.1930, G. Heinrich ( MFNB) .

Distribution. Indonesia (Sulawesi).

Remarks. This species was described by Haupt (1917) based on two female specimens from Minahassa, Celebes. We could not examine its types and identified it in the present samples based on similar external morphology and locality. The species is very similar to C. speilinea , but can be distinguished from the latter by the fore femora without spine near apex ( Haupt, 1917).

CENTROMERIA LONGIPENNIS ( WALKER, 1851)

FIGS 2F , 19A – I

Dictyophora [sic] longipennis Walker, 1851: 316 . Holotype: ♂, Philippines (BMNH) (examined).

Centromeria longipennis (Walker) : Stål, 1870: 745; Melichar, 1912: 43; Metcalf, 1946: 37.

Dictyophora [sic] surgens Walker, 1870: 101 . Holotype: ♀, Indonesia (Amboina) (BMNH) (examined). Synonymized by Melichar, 1912: 43. (Error)

Dictyophara nigroapicata Lethierry, 1888: 467 . Holotype: ♂, Indonesia (Nias) (MNHN) (examined). Synonymized by Melichar, 1912: 43. (Error)

Centromeria bicolorata Bierman, 1910: 14 . Holotype ♂, Indonesia (Java) (NCB Naturalis) (examined). Synonymized by Melichar, 1912: 43. (Error) Redescription. BL, ♂ 15.8 mm; HL, 2.1 mm; HW, 1.5 mm; TL, 12.3 mm.

Male genitalia with pygofer in lateral view narrow and high, with ratio of ventral to dorsal width about 2.4: 1; posterior process near middle elongate, slender, and straight, obtuse apically ( Fig. 19E ). Gonostyles ( Fig. 19E ) relatively large, upper process elongate, acute apically. Aedeagus ( Fig. 19G – I ) small, endosomal processes extended posteriorly and curved dorsoanteriorly, apical one-third membranous, acute apically ( Fig. 19H ); phallobase sclerotized and pigmented at lateral sides, membranous and moderately inflated dorsally and ventrally, with one pair of ventral lobes short and small, without spines ( Fig. 19H, I ). Segment X in dorsal view large and elongate, with ratio of length to width near middle about 1.6: 1 ( Fig. 19D ).

Type material examined. Holotype ♂ of Dictyophora longipennis Walker, 1851 , [ Philippines], Phil Isla, Type, Dictyophora longipennis (BMNH) .

Other material examined. Philippines, 1♂, P.I., Misamis Or., Mount Empagatao , 1050 – 1200 m a.s.l., Rain forest, 19 – 30.iv.1961, H. Torrevillas ( BPBM) .

Distribution. Philippines (northern Mindanao).

Remarks. The locality for this species was given only as ‘Philippine Islands’ by Walker (1851). Melichar (1912) listed it also from Indonesia (Nias, Sumatra, and Amboina), but our results show that C. longipennis redescribed by Melichar (1912) was a misidentification. This species is similar to C. nigroapicata , but can be separated from the latter by the tegmina without fuscous spot on the apical region and the posterior process of the pygofer slender and straight, obtuse apically.
