Lucañas, Cristian C., 2017, Some new brachypterous cockroaches (Blattodea: Blaberidae: Epilamprinae) from the Philippines, Zootaxa 4294 (1), pp. 130-136 : 132-135

Species Cyrtonotula maquilingensis sp. nov. [ Figure 2 A–G]

Material Examined. Holotype: 1 male, Philippines: Luzon, Laguna, Los Baños, Mt. Makiling , 16.ii.2016 (CCLucañas, UPLBMNH BLA-00677 ♂) . Paratypes: 2 male, 4 female: same locality as holotype, 16.ii.2016 (CCLucañas, UPLBMNH BLA-00678 ♂), 20.v. 1967 (AVReyes, UPLBMNH BLA-00679 ♂; 00680—00681 ♀), 20.v.1967 (JJWalawala, UPLBMNH BLA-00682 ♀), 20.v.1967 (ASVarca, UPLBMNH BLA-00683 ♀) .

Distribution. Philippines: Luzon, Laguna (Mt. Makiling; Mt. Banahaw)

Diagnosis: Brachypterous. Vertex exposed. Pronotum subelliptical, slightly produced posteriorly. Tegmina reaching only up to the fourth abdominal tergite in males and third abdominal tergite in female. Wings lobiform. Forefemur type B1. Hind metatarsus distinctly longer than the remaining segments combined. Pulvilli small, apical. Tarsal claws simple, symmetrical. Arolium present. Abdominal tergites unspecialized.

C. maquilingensis differs from C. lata Hanitsch 1929 in terms of the coloration of the face (black anteriorly and brown posteriorly in C. maquilingensis while testaceous in C. lata ) and the length of hind basitarsomere (distinctly longer than the other tarsomere in C. maquilingensis while similar in length with the remaining tarsomeres combined in C. lata ). Unfortunately, C. lata is described only from a single female specimen, which limits the available characters to compare.

Meanwhile, C. maquilinguensis differs from C. secunda Mavropulo, Anisyutkin, Zagoskin, Zagoskina, Lukyantsev , & Mukha in terms of facial coloration (medially black with brown patches on vertex and around the compound eyes in C. secunda ), forefemur armament (type B 1 in C. maquilingensis while B 2 in C. secunda ), an structure of male genital phallomeres ( C. maquilingensis with R3 expanding anteriorly, apex truncate; caudal part of R1 distinctly rounded basally; L2d basally truncate, tapering posteriorly, posterior half curved; L3 hook posteriorly truncate; while R3 thick, apex rounded; caudal part of R1 subrectangular; L2d straight slightly expanding to slightly rounded apex; L3 hook slightly rounded posteriorly in C. secunda ).

On the other hand, C. maquilinguensis differs from C. tertia in terms of facial coloration (entirely black in C. tertia ), armament of forefemur (Type B 2 in C. tertia ), shape of subgenital plate and male genital phallomeres (R3 broad, apex rounded; cpR1T subrectangular; L2d nearly straight, apically rounded; L3 hook tapering posteriorly in C. tertia ).

Description. Size (mm): Holotype. Male: TL: 12.00; Pn: 4.0 x 5.5; Tg: 6.0 x 4.5.

Paratypes. Males: TL: 12.25 ± 0.35; Pn: 4.25 ± 0.35 x 5.75 ± 0.35; Tg: 5.75 ± 0.35 x 4.00. Female: TL: 16.88 ± 0.63; Pn: 5.13 ± 0.25 x 7 ± 0.41; Tg: 7.0 ± 0.41 x 4.88 ± 0.48.

Male ( Fig. 2 A): Mottled brown throughout. Vertex slightly exposed. Head black from vertex to the ocellar spots, brown towards the labrum. Ocellar spots present, slightly below antennal socket ( Fig. 2 B). Pronotum subelliptical, slightly produced posteriorly, with numerous punctations. Tegmina reduced, greatly punctated, apically rounded, reaching only upto the fourth abdominal tergite. Portion of mesonotum exposed even if tegmina are at rest. Wings greatly reduced, not reaching beyond the first abdominal segment when at rest. Forefemur type B1, anteroventral margin armed with four proximal spines followed by a row of piliform spinules terminating in a large apical spine ( Fig. 2 C). Mid femur with a genicular spine; anteroventral margin with three spines and one apical spine; posteroventral margin with three spines and one apical spine. Hind femur with a genicular spine; anteroventral margin armed with three spine and one apical spine; posteroventral margin with one spine. Hind metatarsus distinctly longer than the remaining tarsomeres combined, armed with 2 rows of spine ( Fig. 2 D). Pulvilli small, apical. Tarsal claws simple, symmetrical. Arolium present. Abdominal tergites unspecialized, with several knobs from T3–T7. Supra-anal plate almost entire, with shallow mesal indentation ( Fig. 2 E). Cerci elongate. Subgenital plate asymmetrical. Style similarly sized. Male genitalia as illustrated ( Fig. 2 F): caudal part of R1 distinctly rounded, covered with bristles; R3 elongate broadening apically, tip nearly truncate; apical portion of L2d hammer-like, basal portion covered with chetae; folded structure of L3 distinct, with bristles. L3 terminally blunt, subapical groove and basal sclerite absent, folded structure distinct, bristles present.

Female ( Fig. 2 G): Similar to male but larger. Subgenital plate entire, rounded.

Etymology. Named after the type locality, Mt. Makiling, Los Baños, Laguna.

Remarks. Recently collected specimens from Mt. Makiling were observed on leaf litter and vegetation on areas with trickling water. Despite abbreviation of tegmina and reduction of wings, these cockroaches were noted to jump from low vegetation to another.
