Yasunaga, Tomohide, Yamada, Kazutaka & Artchawakom, Taksin, 2013, New or little known taxa of the plant bug tribe Hallodapini (Hemiptera: Heteroptera: Miridae: Phylinae) from Thailand, with descriptions of three new species of the genus Acrorrhinium Noualhier, Zootaxa 3647 (3), pp. 429-442 : 435-437

Alloeomimus muiri Schuh

( Figs. 3 A–B, 4–7)

Diagnosis. Recognized by the characters mentioned in generic diagnosis, macropterous female (see Remarks), two distinctive white maculae on the corium (anterior larger, triangular macula continuing to the clavus and posterior, wedge-like macula), small genital capsule with the apically tapered phallotheca ( Fig. 4 ), slender, simple male endosoma ( Figs. 5–6 ), and narrow bursa copulatrix ( Fig. 7 ).

Measurements. 3/Ƥ: Total body length 3.0/ 3.3; length from apex of clypeus to cuneal fracture 2.16/ 2.40; head width across eyes 0.60/ 0.62; vertex width 0.30/ 0.41; lengths of antennal segment I–IV 0.27, 1.20, 1.05, 0.84/ 0.24, 1.32, 1.14, 0.75; labial length 1.56/ 1.53; basal pronotal width 0.75/ 0.75; width across hemelytron 0.74/ 0.90; and lengths of metafemur, tibia and tarsus 1.35, 2.10, 0.57/ 1.41, 2.13, 0.59.

Biology. No information is currently available, as all specimens used in this study were collected at light in March.

Specimens examined. THAILAND: Nakhon Nayok Prov.: 13, Sarika (lodge), N14°18'39" E101°18'00", at light, 5 Mar 2009, T. Yasunaga (AMNH_PBI 00379623) (TYCN); 1Ƥ, same data except for date 14 Mar 2009 (00379624) ( SUT); 131Ƥ, Sarika, N14°18'07" E101°18'09", at light, 21–23 Mar 2010, T. Yasunaga & K. Yamada (00379625–00379626) (TYCN).

Remarks. Although all specimens examined during this study correspond in overall appearance to the original description, the male endosoma is somewhat longer than that described and illustrated by Schuh (1984). Because the hallodapine endosoma may be sometimes variable in length and shape, the Thai population is herein regarded to be conspecific with typical muiri (the holotype male from Java). Both of two female adults examined in this study are macropterous ( Fig. 3 B); however, Schuh (1984) mentioned that the paratype females (from Java) are brachypterous.

Clapmarius Distant

Diagnosis. Recognized by the elongate-oval body (nearly conventional form of the Miridae ); brown-castaneous basic coloration; a mesal, longitudinal sulcus on vertex; lamellate, somewhat flattened antennal segment I; Cshaped, short but thick endosoma apically furnished with several sclerotized appendages ( Figs. 5–6 ); and basically toughened bursa copulatrix with distinct sclerotized ring (Fig. 8).

Discussion. Clapmarius is currently represented by four species, known from Peninsular Malaysia, East Malaysia (Borneo), Sri Lanka and Thailand, respectively, and two undescribed species additionally exist in Kuala Lumpur and Sabah (East Malaysia) (Schuh, 1984).

Schuh also commented that the affinities of Clapmarius within the Phylinae can be determined by the flattened pronotal collar and sulcate vertex which may relate this genus to the group of genera including Acrorrhinium within the Hallodapini . However, the exact systematic position of Clapmarius remains unclear, and requires further broader observations on larger numbers of specimens. On the basis of the form of the male endosoma and female bursa copulatrix, Clapmarius is assumed to have the closest relationship with Cleotomiroides Schuh , currently placed in the tribe Auricillocorini (Yasunaga, 2012a) .
